            <abstract>
                <p>This review explores innovative and sustainable strategies for conservation and use of village or indigenous chickens (IC) (
                    <italic toggle="yes">Gallus domesticus</italic>) in Zambia and parts of Sub-Saharan Africa (SSA). Small scale farmers (SSF) have kept IC for hundreds of years to meet their households&#x2019; nutritional needs, incomes, social-cultural and religious uses among others. The commitment exhibited by SSF in keeping IC has made them the major custodians of essential animal genetic resources in low-income regions. Between 1991 and 2012, private breeders invested over US$95 million in Zambia&#x2019;s commercial poultry sector resulting in over 100% increase in annual production of day-old chicks to 65 million. However, high production costs and low market access hindered the participation of SSF, hence their continued dependence on IC. Unfortunately, the future of IC genetic resources is threatened due to the rapid loss and erosion of IC breeds. In the 2015 biodiversity status report, the Food and Agriculture Organisation, an international body of the United Nation highlighted that over 3.5% of IC breeds were extinct, nearly 33% were at high risk and over 67% were of unknown status. Poultry diseases, lack of sustainable conservation strategies and poor use among others have significantly contributed to these losses. For example, in 2012, 60% of IC were diseased in parts of SSA including Zambia. If these challenges are not mitigated, the loss of IC genetic resources and the adverse impact on rural communities are inevitable. Further, future research and breeding programs on commercial chickens may also be limited as a result of erosion of IC genetic resources. Therefore, this paper reviews and contributes to previous studies that demonstrated how researcher-community-stakeholder engagements potentially enhanced sustainability and the adoption of innovative ideas including the potential to increase conservation and sustainable use of local chicken biodiversity in Zambia and parts of SSA.</p>

                <p>Following the reviewer&#x2019;s suggestions and guidance, we made the following changes to version 2 to improve the structure, content, and general organisation of the article: The title was revised and now reads as shown in version 3 to include the wider scope of the value of indigenous chickens to rural communities in Sub-Saharan Africa. The text of the abstract was also revised to relate to the organisation and content of the article. The term indigenous poultry sector was replaced with the indigenous chicken sector The old statistics on the chicken meat and egg tonnages from indigenous chicken were replaced with more recent ones. In the introduction and part of the main body, some paragraphs were moved from one position to the other to improve the sequence and flow of the information in the article. We also added some information and references on community-based interventions. The community-based breeding program was treated as a community-based intervention and thus examples that related to the interventions included other indigenous livestock just to emphasise the point that engaging stakeholders when designing interventions is crucial for adoption and sustainability Some sub-titles were revised in certain parts of the article to reflect the content. We revised the conclusion to make it comprehensive to our readers and consistent with our findings.</p>

            <title>Introduction</title>
            <p>Many countries in Sub-Saharan Africa (SSA) experience varying and distinct agroecological conditions. The region&#x2019;s diverse climate affects individual countries in a variety of ways. In this scenario, Zambia is not exceptional. The country has a total surface area of 752,618 square kilometres (75.3 million hectares), divided into three distinct agroecological regions (I, II and III), each with unique agricultural challenges concerning annual rainfall, vegetation, annual temperatures, soil type and water resources. Agroecological regions I and II occupy 54% of the total national land, mainly in Zambia&#x2019;s Southern, Western, Central and Eastern areas (
                <xref ref-type="bibr" rid="ref43">Phiri and Mukelabai 2010</xref>). Region I and II, on average, receive between 800 mm and 1000 mm annual rainfall. In contrast, region III, primarily in the Northern and North-western, also classified as a high rainfall zone, covers 46% of the national area and receives more than 1000 mm annual rainfall. Despite this climate variability across the country, and over 40% of fresh groundwater in Southern Africa is in Zambia, 90% of small-scale farmers (SSF) practise rain-fed agriculture (
                <xref ref-type="bibr" rid="ref23">Hamududu and Ngoma 2019</xref>).</p>
            <p>Generally, most problems experienced in agriculture are highly associated with climate variations, which may worsen by the next century. Some studies predict that by the end of the twenty-first century, there will be a three degrees Celsius increase in global temperature, 0.6% reduction in annual rainfall, and a 13% reduction in available groundwater due to climate change (
                <xref ref-type="bibr" rid="ref42">Pelletier and Tyedmers 2010</xref>; 
                <xref ref-type="bibr" rid="ref23">Hamududu and Ngoma 2019</xref>). The drastic climate variation will have more adverse effects in low-income countries, especially in SSA. Therefore, small livestock, such as goats, sheep and indigenous chickens (IC) (Gallus domesticus), generally considered low input enterprises, will be essential and expected to contribute substantially to improving livelihoods among rural communities (
                <xref ref-type="bibr" rid="ref51">Simainga et al. 2011</xref>; 
                <xref ref-type="bibr" rid="ref45">Queenan et al. 2016</xref>). Very few SSF have produced broilers and layers in Zambia. Most of them have continued to keep IC because of the low but stable performance under the free-range system (
                <xref ref-type="bibr" rid="ref6">Bagopi et al. 2014</xref>; 
                <xref ref-type="bibr" rid="ref44">PAZ 2021</xref>). Low costs, easiness of rearing and favourable prices of IC encouraged more SSF to consider producing these chickens because they are sustainable and profitable (
                <xref ref-type="bibr" rid="ref39">Okeno et al. 2013</xref>; 
                <xref ref-type="bibr" rid="ref7">Bett et al. 2013</xref>).</p>

                <xref ref-type="bibr" rid="ref19 ref20">Gu&#x00e8;ye (1998, 2000)</xref> highlighted that IC, which comprises the majority of rural poultry farming in SSA, have been kept by SSF for hundreds of years to meet their food and nutritional security, household incomes, poverty reduction and empowerment of women. Some researchers have also documented the significant contribution of IC to farmers&#x2019; adaptation and resilience to climate variations more than larger livestock species such as cattle, which demand more grazing land and water resources (
                <xref ref-type="bibr" rid="ref55">Yayneshet and Treydte 2015</xref>). Studies conducted in various parts of SSA have identified easiness and negligible start-up capital for IC, especially under scavenging or free-range production systems, which are common among rural farmers as motivating factors (
                <xref ref-type="bibr" rid="ref39">Okeno et al. 2013</xref>). Some researchers consider IC an entry point to poverty reduction, as farmers could start with one chicken (
                <xref ref-type="bibr" rid="ref7">Bett et al. 2013</xref>; 
                <xref ref-type="bibr" rid="ref14">Dolberg 2007</xref>;

                <xref ref-type="bibr" rid="ref45">Queenan et al. 2016</xref>).</p>
            <p>Despite these critical roles of IC, rural communities have not achieved significant socioeconomic gains from producing IC. Poultry diseases, poor nutrition, unsupportive policies and low access to markets are partly the causes of the current status of the indigenous chicken sector (IC sector) in SSA. One of the strategies to mitigate the challenges in the sector is to exploit sustainable interventions generated through researcher-community-stakeholder engagements. This approach enables researchers to share information with the rural communities and stakeholders on the benefits of the desired community-based interventions (
                <xref ref-type="bibr" rid="ref48">Rodr&#x00ed;guez et al. 2011</xref>). Several innovations targeting rural communities aimed at promoting sustainable utilization and conservation of AnGR, identifying challenges and exploring opportunities have resulted in increased adoption, enhanced adaptation and socioeconomic gains among rural communities (

            <p>This paper highlights the roles of IC, the main challenges faced by small-scale producers, available opportunities for growth and feasible strategies to mitigate the loss of IC- AnGR and its impact on rural communities in SSA. Further, examples of researcher-community-stakeholder engagements based on IC and other indigenous livestock are highlighted to illustrate the point that community-based interventions are effective tools in promoting sustainable use and conservation of indigenous AnGR and improving rural livehoods in low-income countries. In this paper, the term indigenous chicken refers to chicken breeds, also known as native chickens belonging to a location where they have evolved for thousands of years (

            <p>Agriculture is the main solution to global challenges such as increased cost of living, population growth, poverty, and inequality. Most studies have demonstrated that agriculture provides employment, food and nutritional security, livelihood assets, and gender equality among rural communities, potentially countering the highlighted concerns (
                <xref ref-type="bibr" rid="ref20">Gu&#x00e8;ye 2000</xref>; 
                <xref ref-type="bibr" rid="ref14">Dolberg 2007</xref>; 
                <xref ref-type="bibr" rid="ref12">Boland et al. 2013</xref>). Globally, agriculture contributes 40% to Gross Domestic Product and employs over 1.3 billion inhabitants (
                <xref ref-type="bibr" rid="ref12">Boland et al. 2013</xref>). A majority of SSF in low-income countries consider agriculture as a full-time occupation. For many generations, rural farmers in SSA have grown various crops and kept livestock, including IC, for their livelihoods (
                <xref ref-type="bibr" rid="ref19 ref20">Gu&#x00e8;ye 1998, 2000</xref>). Therefore, as we head towards the year 2050, agriculture is crucial for job creation and meeting the food and nutritional demands in SSA (
                <xref ref-type="bibr" rid="ref26">Klingholz 2020</xref>).</p>
            <p>The Food and Agriculture Organisation (FAO), an international body of the United Nations classifies chickens in the top five crucial animal species, with the other four being cattle, sheep, goats and pigs (
                <xref ref-type="bibr" rid="ref49">Scherf and Pilling 2015</xref>). This international body has made it mandatory for countries to prioritize submitting biodiversity status reports for these farm animal species. Among the chicken species, IC have the highest population and importance for SSF in SSA because most rural farmers produce these chickens at low land, capital and labour requirements (
                <xref ref-type="bibr" rid="ref7">Bett et al., 2013</xref>). Although rural farmers practise low input production systems, there are variations in conditions and environments across the region and within countries based on their socioeconomic status (
                <xref ref-type="bibr" rid="ref19 ref20">Gu&#x00e8;ye 1998, 2000</xref>). Thus far, studies have revealed IC&#x2019;s socioeconomic functions for rural communities in most low-income countries (

Recently, production trends of the IC sector in the region have significantly changed. The proportion of IC compared to the national poultry population from 1989 to 2018 for selected countries in SSA have been reported widely (

            <p>Despite the high percent of IC in the national flock, the IC sector has exhibited varying growth in the past decades compared to commercial poultry sector across the region. The difference in the growth rate between the two poultry sectors is highly associated with the production costs, shortages of feeds and outbreaks of poultry diseases experienced in SSA, mostly affecting SSF (
                <xref ref-type="bibr" rid="ref20">Gu&#x00e8;ye 2000</xref>;

                <xref ref-type="bibr" rid="ref53">Vernooij et al. 2018</xref>). Zimbabwe&#x2019;s case is different, where over 65% contraction in the poultry industry was reported between 2007 and 2018 (
                <xref ref-type="bibr" rid="ref18">FAOstat 2022</xref>). The change may be associated with the country&#x2019;s political and economic difficulties during the Zimbabwean government&#x2019;s 2000-2001 land reforms.</p>
            <p>In Zambia, the socioeconomic contributions of agriculture are equally evident, especially among rural communities. According to the Ministry of Fisheries and Livestock (MFL), nearly 18% of Zambia&#x2019;s Gross Domestic Product is from agriculture, supporting over 12 million people and absorbing over 67% of the labour force (
                <xref ref-type="bibr" rid="ref36">MFL 2017</xref>). Poultry is also a significant component of agriculture in the country. A study conducted in 2012 found that over one million smallholder farmers out of 1,418,000 agricultural households surveyed raised over 12 million IC in Zambia (
                <xref ref-type="bibr" rid="ref29">Lubungu and Mofya 2012</xref>). The study also found that half of the reported chickens were owned by SSF in Eastern, Southern and Central provinces, whereas the other half belonged to SSF in the seven regions. The MFL estimated a 20% annual growth in the Zambian IC sector between 2012 and 2017 (
                <xref ref-type="bibr" rid="ref38">MFL 2019</xref>).</p>
            <p>In the 1990s, the Zambian government made economic reforms in the agriculture sector through a liberalised market system to promote private sector participation in delivering goods and services (

                <xref ref-type="bibr" rid="ref11">Bonaglia 2009</xref>). During this period, privatization of most government-run entities occurred. In 2005, a ten-year plan explicitly for the poultry sub-sector was established (
                <xref ref-type="bibr" rid="ref6">Bagopi et al. 2014</xref>). The plan aimed to increase efficiency and productivity in the commercial poultry sector.</p>
            <p>The agriculture reforms and poultry sector plan led to introduction of new chicken genetics, improved nutrition, enhanced health services and farming practices in the Zambian poultry industry. Within six years, integrated and standalone breeders, such as Zambeef-Rainball, Pioneer-Bokomo, Tiger-Ross, Country bird, Panda and Hybrid, were established (
                <xref ref-type="bibr" rid="ref6">Bagopi et al. 2014</xref>; 
                <xref ref-type="bibr" rid="ref44">PAZ 2021</xref>). Further, a US$95 million investment by Zambeef-Rainball breeders triggered unprecedented growth in the poultry sector. Between 2007 and 2012, the production of day-old chicks rose by over 100%, from 27 to 65 million per annum, and over 50,000 jobs were created (
                <xref ref-type="bibr" rid="ref6">Bagopi et al. 2014</xref>). In contrast, such changes occurred much earlier in highly industrialised nations, as observed in policies that govern the poultry industry and gains made by consumers in those countries (
                <xref ref-type="bibr" rid="ref50">Steinfeld and Gerber 2010</xref>). Generally, changes in Zambia&#x2019;s poultry sector encouraged the involvement of SSF in the commercial poultry sector, defying their conservative nature. However, the participation of SSF was temporal due to the high production costs and anti-competition tendencies they faced in the commercial poultry sector (

            <p>The method used to produce chickens significantly affects productivity and quality. Farmers practise three main chicken production systems. The free-range system, where the chickens scavenge for feed and without health care interventions; the semi-intensive, in which the chickens are partially allowed to scavenge, coupled with feed supplementation; and the intensive, in which the chickens are entirely confined and fed throughout their growth period (

                <xref ref-type="bibr" rid="ref39">Okeno et al. 2013</xref>). Free-range and semi-intensive systems are considered beneficial to SSF, mainly due to negligible start-up costs, i.e. feeds and drugs (

                <xref ref-type="bibr" rid="ref45">Queenan et al. 2016</xref>). However, improving practices on disease control, shelter, marketing, feed supplementing and exploiting available feed resources may increase production, efficiency and profitability among SSF in SSA (
                <xref ref-type="bibr" rid="ref21">Goromela et al. 2006</xref>). Generally, SSF are at liberty to practice any of the three production systems depending on their constraints and socioeconomic status (
                <xref ref-type="bibr" rid="ref20">Gu&#x00e8;ye 2000</xref>). The intensive production system used mainly by commercial chicken farmers is unsustainable for SSF because of the high cost of production, disease prevalence, and the highly oligopolistic market controlled by big breeders and producers (

                <title>Common indigenous chicken breeds</title>
                <p>There are different breeds of IC reared by rural farmers in SSA. The Ministry of Agriculture and Cooperatives (MACO) highlighted various IC breeds that rural communities in Zambia reared. These breeds include the common Zambi, Naked neck, Dwarfs or short-legged, Frizzled feathered, Feathery legged, and Short-tailed, with live bodyweights (BW) range of 1.3-2.0 kg at over 180 days of age (

                    <xref ref-type="bibr" rid="ref44">PAZ 2021</xref>). Studies in Nigeria and Botswana suggest significant differences in live BW between female (0.7-2.1 kg) and male (1.2-3.2 kg) IC (
                    <xref ref-type="bibr" rid="ref20">Gu&#x00e8;ye 2000</xref>). In Benin, some common IC breeds include Koklogbo, Komaloe, Adjagble, Win, and Dingbannon, which are reared by rural communities (
                    <xref ref-type="bibr" rid="ref48">Rodr&#x00ed;guez et al. 2011</xref>). Their fieldwork compared production parameters between IC and exotic breeds and assessed the impact of the NCD vaccination program on the profitability of the two ventures. They reported that IC laid ten eggs per cycle and achieved 2.4 cycles per year, 70% hatchability, 150 days of the growth period at 1.1 kg live BW and 120 days for brooding and maintenance. In contrast, exotic chickens had slightly higher production indicators at 12 eggs per cycle, three cycles per year, 80% hatching rate and a somewhat shorter period of brooding and maintenance at 89 days (
                    <xref ref-type="bibr" rid="ref48">Rodr&#x00ed;guez et al. 2011</xref>). They concluded that IC were more profitable for poor resource farmers compared to exotic. Compared to broilers at 42 days, the growth period for IC is much longer. Recently, Zambia&#x2019;s poultry sector saw the introduction of new chicken breeds. Some improved free-range chicken breeds include the Boschvelds, Kruoillers, Black Australorps and Brahma (

                <title>Food source</title>
                <p>The contribution of IC to food needs for rural households is much more significant than other types of indigenous livestock. Rural families in SSA have met the much-needed animal-based protein by consuming chicken meat and eggs. For example,

There was a significant change in the farmers&#x2019; food and nutritional security and livelihood. Based on production trends between 2009 and 2017, the IC sector has significantly contributed to the poultry meat and egg supply in most countries in SSA (

                    <xref ref-type="bibr" rid="ref53">Vernooij et al. 2018</xref>). In 2016, IC comprised 82.4% of Kenya&#x2019;s 40.4 million chickens (total), and the sector produced over 1,530 million eggs annually. In contrast, in Uganda, 26.6 million (66.5%) were IC, the poultry sector produced 856 million eggs, and Tanzania had 37 million IC (55.2%), producing over 1,780 million eggs annually (

Growth trends for IC were also reported between 2010 and 2020 in Benin at 37.6% from 16.5 million, Nigeria dropped by 13.7% from 192 million IC, and Zambia expanded by 17.4% from 35 million.

                <p>The household consumption levels for IC and related products depend on the productivity and performance of farmers&#x2019; chickens. Communities that experience higher chicken mortalities exhibit low consumption levels for IC meat and eggs, and eggs are solely for hatching and replacement stock, and in contrast, chickens are typically sold to raise household incomes (
                    <xref ref-type="bibr" rid="ref10">de Bruyn et al. 2018</xref>). Global consumption trends for poultry products show that from 2004 to 2012, a 9% increment in chicken meat to 63 million MT and a 20% rise in egg consumption to 55.5 million MT was reported (
                    <xref ref-type="bibr" rid="ref49">Scherf and Pilling 2015</xref>). The number of eggs consumed annually per person varies from country to country. From 2009 to 2017, Kenya, Tanzania and Nigeria experienced reductions at (0.6-0.5), 1.6-1.5) and (1.6-0.9) eggs/person/year, respectively. The egg consumption rates in SSA were significantly low at (2.1) eggs/person/year compared to over 13 eggs, the global average (

                <p>The consumption of IC meat and eggs is highly dependent on the socioeconomic status of the community and, in future, the growth in human populations (

                <title>Loss of indigenous chicken animal genetic resources</title>
                <p>The continued erosion of IC-AnGR and the low socioeconomic gains by rural farmers producing IC are potential threats to rural livelihoods in SSA. These chickens are highly adapted to conditions, able to use scavenged feeds efficiently, incubate and brood naturally making them more sustainable for small-scale scavenging systems in SSA (Riise et al. 2004; 
                    <xref ref-type="bibr" rid="ref48">Rodr&#x00ed;guez et al. 2011</xref>). The 2015 biodiversity status report by FAO revealed that over 3.5% of chicken breeds were extinct, 33% were at high risk, and about 67% were in the unknown status category (
                    <xref ref-type="bibr" rid="ref49">Scherf and Pilling 2015</xref>). In SSA, 80% of SSF keep IC, significantly contributing to the IC sector, making them the primary custodians of IC-AnGR in the region. If there are no measures to stop or reduce the loss of IC-AnGR, the rural communities in low-income countries are likely to suffer.</p>

                <p>The decision by SSF in many parts of SSA to reconsider the rearing of IC is a viable socioeconomic strategy. However, the growth of the IC sector is hindered significantly by poultry diseases (

In Zambia, NCD, fowl pox, typhoid, infectious coryza, Gumboro, worm infestation, and external parasites have significantly contributed to the poor performance and high mortalities experienced in the IC sector (

                <p>In 2012, over 27% of SSF in Zambia relied on traditional medication, and less than 15% used veterinary drugs, resulting in 60% of the IC dying (
                    <xref ref-type="bibr" rid="ref29">Lubungu and Mofya 2012</xref>). The FAO rates poultry diseases and poor disease management at 28%, introducing exotic animal breeds at 22%, uncontrolled cross-breeding at 63% and climate change at 16% as responsible for the loss of chicken breeds globally (
                    <xref ref-type="bibr" rid="ref49">Scherf and Pilling 2015</xref>). Despite the high disease prevalence observed in IC, there are some beneficial adaptability and genetic gains through natural selection.</p>
                <p>Indigenous chickens have evolved in their current and uncontrolled environments evident through developing disease resistance and high adaptation to low-quality diets (

                <title>High cost of inputs and nutritional limitations</title>
                <p>Nutritional problems are mainly due to high feed costs and poor chicken feeding regimes among SSF. The cost of feeds and other live inputs in the Zambian poultry industry generally increased in the past five years. The high costs of poultry feed in SSA are attributed to ever-rising prices for soya beans and maize (
                    <xref ref-type="bibr" rid="ref6">Bagopi et al., 2014</xref>; 
                    <xref ref-type="bibr" rid="ref53">Vernooij et al., 2018</xref>). The Poultry Association of Zambia (PAZ), an affiliate of the Zambia farmers Union, has been publishing weekly reports covering prices for poultry inputs. The association reported price changes for feed, feed ingredients and live inputs for the first quarters between 2016 and 2021; the solvent-extracted soybean meal increased by 27.7% from US$23.50 per 50 kg, and 45.3% increase for broiler starter from US$20.10 per 50 kg. Further, prices for broiler grower increased by 44% from US$19.30 per 50 kg, and finisher increased by 45.9% from US$18.50 per 50 kg, whereas a 49% increase in layer mash from U$14.70 per 50 kg (
                    <xref ref-type="bibr" rid="ref44">PAZ 2021</xref>). Other price increments included day-old chicks for improved free-range chickens, layers and broilers at 87.5%, 83.3% and 125% from US$0.80, US$0.60 and US$0.40 per bird, respectively. Market prices for pullets, broilers, spent layers, and IC increased by 64.8%, 57%, 38.5% and 61.5% from US$8.90, US$3.00, US$2.60 and US$3.90 per bird, respectively (
                    <xref ref-type="bibr" rid="ref44">PAZ 2021</xref>). The high prices for feed and other live inputs have hindered SSF from participating entirely in the commercial poultry sector in SSA (
                    <xref ref-type="bibr" rid="ref53">Vernooij et al. 2018</xref>). The proportinal increment in feeds costs with increased flock sizes observed in exotic or commercial chickens is the major factor contributing to reduced profits compared to IC sector (
                    <xref ref-type="bibr" rid="ref48">Rodr&#x00ed;guez et al. 2011</xref>).</p>
                <p>Limited supplementary feeding and a lower plane of nutrition under the scavenging system lead to mortalities and reduced consistency in chicken (eggs) size and quality (
                    <xref ref-type="bibr" rid="ref45">Queenan et al. 2016</xref>). The majority of the IC are left to roam and scavenge for feed sources, such as insects, termites, vegetables, seeds, grains and earthworms, and in some instances, farmers supplement the chickens with kitchen waste, maize bran, leafy vegetables and other cheap feed sources (
                    <xref ref-type="bibr" rid="ref30">Mwalusanya et al. 2002</xref>;

                <p>There are also fluctuations in the availability of scavenged feed resources between one harvest and the following year&#x2019; in rain-fed farming systems in SSA (
                    <xref ref-type="bibr" rid="ref10">de Bruyn et al. 2018</xref>). In Zambia, the scavenging chickens have access to high-protein insects and earthworms in the rainy season (December to April) and high-energy feed sources during the harvest time from May to August. However, in the hot and dry season, a severe shortage of nutritious feeds leads to poor health, malnutrition and high mortalities (
                    <xref ref-type="bibr" rid="ref45">Queenan et al. 2016</xref>). The dry season requires deliberate feed supplementation to mitigate adverse effects on IC (
                    <xref ref-type="bibr" rid="ref10">de Bruyn et al. 2018</xref>). In some parts of SSA, breeding black soldiers fly larvae and maggots as protein sources are being experimented with and may improve nutrition in the IC sector, especially in periods of scarcity (

                <title>Inadequate policies and regulations to support the indigenous chicken sector</title>
                <p>The existing policies governing the poultry sector are generally inadequate in SSA. Most policies and trade restrictions are in favour of commercial poultry producers. In Namibia, poultry producers legally brine broiler meat at 20%; in Botswana, commercial producers are allowed to supply 75% of poultry meat demand, whereas brined poultry meat is not allowed (
                    <xref ref-type="bibr" rid="ref6">Bagopi et al. 2014</xref>).</p>
                <p>Infrastructure development is more leaned toward larger farms (
                    <xref ref-type="bibr" rid="ref14">Dolberg 2007</xref>). Most governments in SSA allocate more funds to infrastructure development, favouring larger livestock species predominantly run by commercial entities. Furthermore, minimal attention goes to the IC sector, despite SSF being part of the primary data source when designing policies on funding and infrastructure (
                    <xref ref-type="bibr" rid="ref14">Dolberg 2007</xref>; 
                    <xref ref-type="bibr" rid="ref49">Scherf and Pilling 2015</xref>). In Zambia, the livestock infrastructure support project funded by African Development Bank focused on the construction of dairy and beef infrastructure. The Second National Agriculture Policy of 2016 to 2020 did not provide a good roadmap on value addition and market participation for SSF involved in the IC sector (
                    <xref ref-type="bibr" rid="ref36">MFL 2017</xref>). The inadequate policies exacerbate the problems experienced in the IC sector, and rural farmers feel neglected by political leaders and inadequately represented by scientists (

                <p>Low-income countries have witnessed economic growth, particularly in the private sector. The observed changes are motivated by inadequate regulations and policies that negatively affect ecosystems, AnGR and the markets (
                    <xref ref-type="bibr" rid="ref49">Scherf and Pilling 2015</xref>). Poultry products worth millions of dollars are imported overseas to SSA, negatively impacting local poultry sectors. In 2018, South Africa imported frozen poultry products of mixed parts valued at over US$65 million from different sources in Brazil (
                    <xref ref-type="bibr" rid="ref44">PAZ 2021</xref>). These posed a public health threat because they lacked traceability and affected the local poultry sector. In Ghana, over US$60 million of poultry products were imported into the country, flooding the local market in 2018 (
                    <xref ref-type="bibr" rid="ref44">PAZ 2021</xref>). These importations prompted the Ghanaian poultry association to engage the government in introducing quotas on poultry imports to protect local poultry farmers. In Namibia, the government sanctioned the importation of poultry products to mitigate the adverse impact on the local poultry industry. In Zambia, the Poultry Association of Zambia continued to engage the government to promote policies protecting and enhancing farmers in the commercial and IC sectors (
                    <xref ref-type="bibr" rid="ref44">PAZ 2021</xref>). Some policy researchers recommend factoring in some livestock production policies and legislation on consumption to existing environmental management policies that could enrich strategies, enhance community benefits and reduce food wastage (

                <title>Low access to formal and stable markets</title>
                <p>In SSA, farmers in the IC sector face barriers preventing them from accessing organised markets. These obstacles are associated with market standards and requirements, such as selling frozen whole or portions of chickens, packaging, labelling, and selling from standard outlets (
                    <xref ref-type="bibr" rid="ref6">Bagopi et al. 2014</xref>). Producers in the IC sector cannot compete with larger commercial entities because they neither own the required facilities, brands or organised sales outlets (

                    <xref ref-type="bibr" rid="ref45">Queenan et al. 2016</xref>). With many obstacles to the established markets, SSF can only sell their chickens or eggs directly to these markets through groups and intermediaries who manage most market channels (

                    <xref ref-type="bibr" rid="ref45">Queenan et al. 2016</xref>). This way is also full of obstacles.</p>
                <p>In Zambia, SSF sell chickens through informal places, such as the roadside, village markets, the backyards, and direct to consumers (

                    <xref ref-type="bibr" rid="ref44">PAZ 2021</xref>). In many parts of the country, informal markets have recently transformed into essential selling points, making it possible for farmers to organise and meet consumers&#x2019; demands on quality and quantity. For example, &#x201c;Tuesday and Saturday markets&#x201d; have become popular in some parts of the country (
                    <xref ref-type="bibr" rid="ref44">PAZ 2021</xref>). In the Northern part of Zambia, this traditional market is also called Munada, where traders agree on the date and place for the market day.</p>
                <p>Low access to reliable markets generally affects IC sales, prices and consumption dynamics among rural communities. For example, in Tanzania, the SSF sold twice more village chickens and eggs to rural areas than they consumed and sold at US$3.72 per live chicken. In contrast, producers of IC in Zambia consumed more than half of their chickens and only sold 20% to urban areas at an average price of US$3.37 per bird (
                    <xref ref-type="bibr" rid="ref45">Queenan et al. 2016</xref>). The variation in selling points and consumption levels shows how undefined and informal the markets for IC are in SSA.</p>

                <title>Poor housing facilities</title>
                <p>Another constraint is the lack of reliable poultry housing facilities for IC under scavenging systems. Some farmers keep their chickens in undeveloped poultry structures at night to secure them from predators. In many cases, chickens seek shelter in trees, making them vulnerable to predators, such as cats and dogs (

                    <xref ref-type="bibr" rid="ref50">Steinfeld and Gerber 2010</xref>). Globally, from 2000 to 2050, researchers predict an 82% increase in meat consumption, equivalent to 233-271 million MT, of which 88 million MT is poultry and over 183 million MT from bovine, ovine and pig meat combined (

However, the volumes demanded will be substantial, especially in SSA, where the farming population will get older, and a majority will migrate to urban areas as the middle class expands (

These are: (i) enhancing knowledge on the characterisation of local animals, (ii) developing sufficient institutional frameworks for AnGR management, enhancing linkages among livestock farmers and stakeholders concerning policies and programmes, and (iii) Enhance awareness through education, training and research in significant areas of AnGR management, (iv) Enhancing breeding strategies and programs to harness available AnGR and match them with environments of production and requirements of societies and (v) increase diversification of conservation programs and possibly mix some approaches that use existing livestock breeds in the typical production environment and consider gene banks&#x2019; use to store genetic materials. To implement the five areas, FAO required individual countries to undertake various programs toward the stated strategies by forming AnGR conservation committees and submitting biodiversity status reports to the FAO Commission on biodiversity (

                <p>Despite researchers sharing a consensus on the socioeconomic roles of IC in SSA, there are fewer attempts to holistically find solutions to challenges faced in the IC sector, including the continued loss of IC-AnGR and low socioeconomic gains by SSF (

The Poultry Association of Zambia expressed similar concerns regarding obscure solutions for SSF in Zambia&#x2019;s poultry sector. Generally, the problems faced by the IC sector in SSA are also associated with unsustainable use of IC-AnGR, lack of animal management and disease control skills, and absence of value addition, among others (

            <p>
                <xref ref-type="bibr" rid="ref34">Mueller et al. (2015)</xref> outlined the process required when establishing community-based interventions and gave examples of such approaches in developing countries that worked and those that faced challenges. The community-based intervention plans had standard features, including initiators being either the community or government research institutions, well-formulated breeding objectives based on indigenous or local breeds, the existence of institutional support and each of the plans recorded a change (
                <xref ref-type="bibr" rid="ref16">Dumas et al. 2017</xref>;

                <xref ref-type="bibr" rid="ref48">Rodr&#x00ed;guez et al. 2011</xref>).</p>
            <p>Various researchers empirically reported the impacts of community-based interventions in low-income countries. For example, in Vietnam, pork farmers achieved between 40% and 100% increment in pork prices resulting from SSF working with government institutions to identify market and pricing challenges and design solutions (Mueller, 2015). In Kenya, SSF experienced fast growth in the goat population and over 300% increase in goat milk yields from 0.25 litres per day after community-based solutions. In Ethiopia, positive testimonies and knowledge-sharing among SSF led to the widespread adoption of sheep breeding strategies among rural communities (
                <xref ref-type="bibr" rid="ref34">Mueller et al. 2015</xref>). There are also instances of community-based interventions targeting the IC sector.</p>
            <p>In Benin, the researchers mobilised farmers to undertake a vaccination program against NCD and facilitate improved poultry management of IC and exotic chickens. Before the community-based intervention, exotic chickens sold 20% more than IC, whereas IC showed profitability of 58% more (
                <xref ref-type="bibr" rid="ref48">Rodr&#x00ed;guez et al. 2011</xref>). After vaccination, mortality in both flocks was reduced by 5%, and exotic chickens sold 53% more than IC. However, the rapid increase in flock sizes of exotic chickens resulted in increased feed costs by 300% and a reduction in overall profits by 38%. In contrast, feed costs for IC flocks under free-range remained negligible regardless of the change in flock size.</p>
            <p>In Zambia&#x2019;s Luangwa Valley, researchers implemented two community-based programs targeting communities producing IC in Mambwe and Lundazi districts of the Eastern province (
                <xref ref-type="bibr" rid="ref16">Dumas et al. 2017</xref>). Firstly, NCD vaccination programs and workshops provided guidelines on improved flock management. In the second intervention, researchers facilitated and supported the construction of semi-intensive egg production structures in 24 communities, and each group had up to five farmers managing 40 hens. After analysing various data from surveys and other secondary records, they found that the flock sizes increased by over 135% within four years, from 10.9 birds and that annual incomes from poultry rose by 138% from US$16.89 (
                <xref ref-type="bibr" rid="ref16">Dumas et al. 2017</xref>). However, the consumption of chickens and eggs did not change much as farmers mainly sold the birds. Impacts of the second intervention included over 62% increase in egg productivity, average group income was over US$30 monthly, consumption of eggs increased by 118% among producers, 167% from 0.9 eggs per week in women and 263% from 0.8 eggs per week among children (
                <xref ref-type="bibr" rid="ref16">Dumas et al. 2017</xref>). The two interventions not only improved communities&#x2019; livelihoods but also promoted sustainable alternatives to the consumption of bush meat, which was detrimental to the ecology of the protected area.</p>

                <title>Useful lessons from other low-income countries</title>
                <p>Generally, there are issues related to community-based interventions, including instances where particular challenges hindered the progress of these interventions. 
                    <xref ref-type="bibr" rid="ref34">Mueller et al. (2015)</xref> highlighted a lack of trust in financial matters and technical problems that potentially affected the sustainability and continuation of particular interventions. For example, in Bolivia, where the objective of the intervention was to improve the fibre quality of wool from llamas, problems such as politics, financial mistrust, and funding challenges resulted in low sustainability and the eventual collapse of the innovation (
                    <xref ref-type="bibr" rid="ref34">Mueller et al. 2015</xref>).</p>
                <p>Promoting poultry development plans based on exotic breeds instead of IC would be less valuable to resource-poor SSF. The new breeds may not adapt to the uncontrolled environment in rural communities (
                    <xref ref-type="bibr" rid="ref49">Scherf and Pilling 2015</xref>). Some challenges associated with exotic breeds include low literacy, lack of records, diseases, high prices and production costs for SSF (

                    <xref ref-type="bibr" rid="ref48">Rodr&#x00ed;guez et al. 2011</xref>). Therefore, considering the local context, IC breeds, and promoting ownership of the intervention formulated through engagements of stakeholders is crucial to the sustainable conservation of IC-AnGR in SSA. The erosion of IC-AnGR is one urgent challenge which requires immediate interventions to secure the highly adapted chicken breeds and ensure better livelihoods for rural communities in SSA.</p>
                <p>The voices and views of the target rural communities and understanding the local situation are essential in intervention programs (
                    <xref ref-type="bibr" rid="ref41">Patton 2010</xref>; 
                    <xref ref-type="bibr" rid="ref13">Bryman 2016</xref>). Analysis of various community-based interventions in low-income countries showed that research institutions and government support were crucial in achieving the established objectives (

                    <xref ref-type="bibr" rid="ref48">Rodr&#x00ed;guez et al. 2011</xref>). Institutional support motivates farmers to open up to their challenges, work hard and feel a sense of ownership of the program.</p>
                <p>Zambia has strived to adhere to the guidelines of FAO. The country implements planned programs through research and extension services of the Ministry of Fisheries and Livestock. Agendas such as farmer engagements and capacity building with donor support on climate-resilient projects, establishing livestock breeding centres across the country, promoting farmer-driven innovation such as community-based programs on IC, multiplication of IC breeds at Mazabuka research station in the Southern province of Zambia (

                <p>Developing a sustainable IC sector based on understanding the production systems used by SSF, clearly defined roles of stakeholders, and the analysing the value of IC has the potential to strengthen its sustainable conservation and enhance rural livelihoods in SSA.

            <title>Conclusion</title>
            <p>Indigenous chickens are an integral component of agriculture among resource-poor communities in Sub-Saharan Africa. These chickens have the potential to contribute to food and nutritional security, increased household incomes and access to livelihood assets for small-scale farmers in Sub-Saharan Africa. Addressing concerns about the loss of indigenous chicken genetic resources and the low socioeconomic gains among rural communities requires strategies inclusive of the targeted communities. Researchers must consider the context of farming and production systems in which the communities thrive. Researchers and stakeholders would have a consensus on indigenous chickens&#x2019; current and future roles, existing opportunities, common challenges and what interventions would work sustainably. Some notable areas that need urgent attention in the indigenous chicken sector include developing farmer skills in poultry management, productivity, value addition, disease control, and linkages to formal markets. A sustainable indigenous chicken sector will enhance rural livelihood and increase the sustainable conservation and utilization of indigenous chicken breeds in Sub-Saharan Africa.</p>

        <body>
            <p>I have read the revised paper and acknowledge that the authors have addressed some of my previous suggestions. The paper, however, still needs improvement before it can be indexed in an international scientific journal. First, the manuscript needs thorough editing for grammar, tense and punctual errors. These errors are just too many to mention one by one. 
                <bold>I also suggest that, to ensure that ALL comments are addressed, the authors should include a</bold>
                <bold> </bold>
                <bold>response to reviewer&#x00a0;letter that specifies how they addressed each of the comments below</bold>.&#x00a0;</p>
            <p> </p>
            <p> Although there is improvement, I am still concerned about flow of ideas in the manuscript. As I indicated my previous comments, all sentences in a single paragraph should be supporting the main idea of the paragraph. For example, page 5 second last paragraph, what is the main idea of the &#x2018;paragraph&#x2019;? Page 7 Paragraph 1 under &#x201c;Diseases and poor nutrition&#x201d;, diseases and nutrition could be discussed in two different paragraphs. Without well-written paragraphs that flow logically from one idea to the next, the manuscript will be difficult to comprehend.</p>
            <p> </p>
            <p> There is repetition in the document. For example, the section on &#x201c;diseases and poor nutrition&#x201d; briefly highlights nutritional challenges faced by the indigenous poultry sector in sub-Saharan Africa but there is also another section on &#x201c;nutritional challenges&#x201d;.</p>
            <p> </p>
            <p> Paragraphs 2 and 4 on page 5 also have repeated information. There is more information which I think is repeated in the document, try to rectify this.</p>
            <p> </p>
            <p> Page 3 paragraph 2 - Why are small stock important in the face of climate change? In this paragraph or the next one (I think these two paragraphs should be combined &#x2013; see comment on paragraphing), authors should justify why the focus is on indigenous chickens.</p>
            <p> </p>
            <p> Page 4 Paragraph 1 - &#x201c;This paper highlights the role of indigenous poultry&#x2026;&#x201d;. Shouldn&#x2019;t it be &#x201c;indigenous chickens&#x201d;? These terms are used interchangeably throughout the document. This should be corrected. The same applies to the terms IC-AnGR and AnGR.</p>
            <p> </p>
            <p> I think the section on &#x201c;roles of agriculture and the value of indigenous chicken genetic resources in low-income countries&#x201d; should be replaced by something like &#x201c;The Sub-Saharan poultry industry&#x201d; or &#x201c;The Zambian poultry industry&#x201d;. The section should mainly discuss the structure of the poultry industry including statistics, need be.</p>
            <p> </p>
            <p> Page 5 Paragraph 1 - The statistics given here are just too old. Some over thirty years ago. Do they still hold value? Just like I emphasized in my previous comments, it is important that authors use young literature throughout the review.</p>
            <p> </p>
            <p> Page 6 paragraph 2 - The topic is on chickens, but authors discuss guinea fowls in this section. Digression.</p>
            <p> </p>
            <p> The section &#x201c;Zambia&#x2019;s poultry industry&#x201d; can be merged with section on &#x201c;roles of agriculture and the value of indigenous chickens&#x2026;&#x201d; and renamed &#x201c;The Sub-Saharan poultry industry&#x201d; or &#x201c;The Zambian poultry industry&#x201d;. See comment above.</p>
            <p> </p>
            <p> More literature should be covered on the indigenous chicken breeds found in Zambia. Which breeds are common? Their performance?&#x00a0;Are there pure breeds?...etc.</p>
            <p> </p>
            <p> Page 9 - I suggest you include a subtopic on strategies to improve indigenous chicken production in Sub-Saharan Africa or Zambia. Maybe this can replace &#x201c;research innovation and application&#x201d;?</p>
            <p> </p>
            <p> Is &#x201c;increased consumer demand for indigenous chickens&#x201d; a strategy to increase indigenous chicken production?</p>
            <p> </p>
            <p> I am failing to understand how subtopics such as &#x201c;increased consumer demand for indigenous chickens&#x201d;, &#x201c;population growth and food demand&#x201d;, &#x201c;food consumption patterns&#x201d; fit under &#x201c;research innovation and application&#x201d;</p>
            <p> </p>
            <p> Page 9 paragraph 4 - The statistics in the last sentence is outdated, from 21 years ago.</p>
            <p> </p>
            <p> Page 9 paragraph 5 - what is the meaning of the phrase &#x2018;period under review&#x201d;? this should be corrected throughout the document. The sentence &#x201c;&#x2026;US$1 was equivalent&#x2026;&#x201d; should be deleted. In this paragraph, authors highlight an important point that there is a market gap for indigenous chickens. So how can this market gap be addressed? Are indigenous chickens producers aware of this gap? I think the creation of market linkages can be a very useful strategy in promoting sustainable productivity of indigenous chickens in SSA. Authors might want to comment on this</p>
            <p> </p>
            <p> Page 10 - Maybe the subtopic &#x201c; Farmer mobilisation and sustainable interventions&#x201d; can be changed to &#x201c;intervention strategies for&#x2026;&#x201d; &#x00a0;</p>
            <p> </p>
            <p> Page 10 paragraph 1 - Authors highlight the issue of loss of IC-AnGR. IC-AnGR should be defined on first mentioning in text. This should be the case with all abbreviations and acronyms. The&#x00a0;loss&#x00a0;of indigenous chicken breeds and strains is a big challenge in SSA.&#x00a0; Authors should include more literature on this &#x00a0;&#x00a0;under the subtopic &#x201c;Threats to the indigenous poultry sector in Sub-Saharan Africa&#x201d;. Why are some of challenges highlighted here (continued loss of IC-AnGR, lack of skills in animal management and absence of value addition) not discussed in detail under the subtopic &#x201c;Threats to the indigenous poultry sector in Sub-Saharan Africa&#x201d;?</p>
            <p> </p>
            <p> Page 10 paragraph 2 - Authors tend to revert to discussing livestock and AnGR in general. They should focus on indigenous chickens. As I emphasized in my previous comments, authors should find a logical way to order and link their sentences, paragraphs and sections of the review. I would expect the review to start with a very brief broad background on livestock or just indigenous livestock, move on to poultry and then narrow towards indigenous chickens, not the other way round. &#x00a0;</p>

                            <p> - The mention of other indigenous livestock was mainly useful in illustrating instances where Community-based interventions have worked in low-income countries and what challenges have been faced in those regions.</p>

                            <p> - Community-based programs are interventions that emanate from engagements between the researcher and the community. The main objective is to address a challenge related to indigenous livestock and breeding potential. So, solutions are created by researchers working together with farmers. The Community based indigenous poultry development program was a concept which would use some common principles found in CBBP such as working with small-scale farmers and focusing on Indigenous livestock breeds etc</p>

            <p>The manuscript entitled &#x201c;Strategies of enhancing rural livelihoods and promoting sustainable use and conservation of indigenous chicken breeds in Zambia&#x201d; discusses the importance of and ways to improve indigenous chicken production in Zambia. I think the effort is useful and provides a perspective on the role of indigenous chickens on resource-poor households in Zambia. I am, however, concerned about the organization, readability, and flow of ideas in the manuscript. The manuscript is difficult to comprehend and needs to be edited carefully. I encourage the authors to improve the manuscript after paying attention to the comments below: 
                <list list-type="bullet">
                    <list-item>
                        <p>I suggest &#x201c;Strategies of promoting sustainable use and conservation of indigenous chicken breeds in Zambia&#x201d; as the title.</p>
                    </list-item>
                    <list-item>
                        <p>Generally, although it is important to make the review of broad interest, the authors should avoid digressing. The topic and objective suggest that the review is on indigenous chicken production in Zambia, but the manuscript ended up covering the whole of Sub-Saharan Africa and even other countries such as Ghana, Senegal, Kenya, Gambia, Morocco, Nigeria, Tanzania etc. While it is important to compare indigenous chickens production in Zambia to other developing regions, it is more important not to lose focus.</p>
                    </list-item>
                    <list-item>
                        <p>The authors need to find a logical structure for the review. There is no clear flow of ideas. For example, the introduction starts with a discussion/background on chicken production and then, in paragraph 3, the focus shifts to goats, sheep and poultry in general. The authors then go back to indigenous chickens in the last paragraph. Initial sections of the review were on indigenous chickens but broadened towards all livestock or, maybe, all indigenous livestock. Authors should find a logical way to order and link the sentences, paragraphs and sections of the review.</p>
                    </list-item>
                    <list-item>
                        <p>The document has too many acronyms. This makes reading and understanding the manuscript difficult. &#x00a0;Acronyms such as RPF, IC, RCS, IPS, SSF, AER, ARF, FRS and SIS can be avoided.</p>
                    </list-item>
                    <list-item>
                        <p>Throughout the document, some statements/facts are not backed by relevant citations.</p>

                        <p>The section entitled &#x201c;Agriculture and indigenous chickens&#x201d; focuses on chickens. Less, if anything, is on other agricultural practices. The title should be revised.</p>

                        <p>Page 4, Paragraph 2 - Avoid starting a paragraph with the word &#x201c;therefore&#x201d;. Paragraphing in the manuscript needs to be improved. A paragraph should start with a &#x201c;topic sentence&#x201d; which introduces the idea to be discussed in the paragraph and the rest of the sentences in the paragraph should be linked to or be an expansion of the topic sentence.</p>
                    </list-item>

                    <list-item>
                        <p>Some of the references used on the production statistics are too old. Surely production statistics reported in 1989 and 1984 would have changed by now? Authors should use mostly young literature throughout the document. Some of the sections, e.g. paragraph 4, lines 7- 9, do not add value to the review and should be deleted.</p>

                        <p>Page 7, paragraph 8 - Isn&#x2019;t this repetition? The preceding section also includes nutritional challenges (at least according to the section heading). Southern Africa is rich in supplements for indigenous chickens. Communal farmers grow crops such as sorghum, finger millet sunflower and millet which can be used to feed chickens. Some of these crops are drought resilient. Is nutrition really a big problem for indigenous chickens under communal systems in Sub Saharan Africa? Maybe when it comes to commercialization of the indigenous chickens.</p>
