Mitigating climate change impacts on food security via climate-smart agriculture

Climate change and agriculture are interlinked and affect each other globally. The global population continues to rise while food and nutritional insecurity remain main global challenges facing humanity. Traditional agriculture methods need transformation to climate smart agriculture (CSA) approaches that have potential to improve food production amidst climate change realities. The review aimed at evaluation of published literature on CSA, establishment of CSA linkages with national development plans for Uganda and Ethiopia, African Union Agenda 2063, UN Sustainable Development Goals and CSA contribution to biodiversity conservation across the globe. Additionally, the review aimed at identifying opportunities and challenges of CSA in the 21^st Century and recommend possible options for all stakeholders for improved income, environmental conservation, and food and nutritional security. Literature search from 2000-2019 was carried out using key words and key phrases in relevant journals and authentic websites. It was found out that CSA supports three pillars: 1) Sustainably increasing agricultural productivity and incomes, 2) Adapting and building resilience to climate change, 3) Climate change mitigation and contributes to Biodiversity Conservation and management. CSA approach has potential to improves food security and farmers’ income. CSA has a vast number of opportunities that include availability of crop genetic diversity, availability of interested CSA researchers, gene banks for genome resources for CSA crop enhancement; enhanced technology for CSA practices that can be accessed by farmers and vibrant research organizations and donor agencies interested in promoting CSA approaches. CSA challenges were identified to include: limited technical and financial capacity and negative attitude from smallholder farmers. It was concluded that CSA approach is a better option for the present and centuries to come farmers across the globe for the attainment of the United Nations (UN) Sustainable Development Goals (SDGs) 2015-20130, UN Agenda 2063 and national development plants of most African countries including Uganda and Ethiopia. The review recommended that capacity building for farmers and researchers need to be done and governments and donor agencies should provide soft CSA loans to farmers to supporting CSA practices and technologies in all developing countries and the approach should be adopted by all the farmers and be promoted by all stakeholders at all levels in both the present and future centuries.

In the face of climate change and extreme weather events which continue to have significant impacts on agricultural production, climate-smart agriculture (CSA) has emerged as one important entry point in reducing the emission of greenhouse gases and building climate resilience while ensuring increases in agricultural productivity with ensuing implications on food and nutrition security. We examine the relationship between CSA, land productivity (yields), and food security using a survey of farm households in Ghana, Mali, and Nigeria. To understand the correlates of the adoption of these CSA practices as well as the association between CSA, yields, and food security, we use switching regressions that account for multiple endogenous treatments. We find a positive association between the adoption of CSA practices and yields. This increase in yields translate to food security as we observe a positive association between CSA and food consumption scores. Although we show modest associations between the independent use of CSA practices such as adopting climate-smart groundnut varieties, cereal-groundnut intercropping, and the use of organic fertilizers, we find that bundling these practices may lead to greater yield and food security gains. Under the different combinations, the use of climate-smart groundnut varieties exhibit the strongest association with yields and food security. We also estimate actual-counterfactual relationships where we show that the adoption of CSA practices is not only beneficial to CSA adopters but could potentially be beneficial to non-CSA adopters should they adopt. These results have implications for reaching some of the sustainable development targets, especially the twin goals of increasing agricultural productivity and maintaining environmental sustainability.

This paper investigates Climate Smart Agriculture (CSA), a comprehensive strategy aimed at improving agricultural efficiency and sustainability while addressing the challenges of climate change. It examines the economic advantages of CSA for adopters compared to traditional farming methods and assesses CSA's role in mitigating climate change, adapting to its impacts, and enhancing food security. The study reviews essential CSA practices, including agroforestry, conservation agriculture, water-efficient irrigation technologies, crop diversification, improved livestock management, and soil carbon sequestration, as well as the barriers to adoption, such as limited funding, arable land, land tenure issues, and insufficient expertise. Agroforestry and crop rotation have shown encouraging results, with agroforestry serving as a cost-effective solution for food production and environmental preservation. Dairy companies boosted milk consumption from 529,000 to 3 million liters, while farmer profits grew from $0.2 to $0.3 per liter. Rice yields have increased, from 3-4 tons to 7.5 tons per hectare. In cotton farming, CSA adopters cut input costs compared to traditional methods, resulting in long-term economic gains. Crop rotation increased maize productivity by 5–10%, while new irrigation techniques improved water efficiency by 5–35%. However, regions without CSA methods experienced significant livestock losses, highlighting the importance of widespread adoption to ensure resilience. Despite CSA’s advantages, its widespread adoption is hindered by financial and knowledge barriers. Future research should focus on optimizing multiple cropping systems, crop diversification, and no-till agriculture. CSA, particularly when integrated with technologies like the Internet of Things (IoT), offers a promising path toward more adaptive and resilient agricultural practices. Broader adoption will require investments in research and resources to effectively scale CSA innovations.

The climate challenges confronting agriculture are multiple, interconnected and multi-scaled. Agriculture is a source of increasing greenhouse gas emissions, but it is also vulnerable to climate change impacts. Adopting resilient approaches in the agricultural industry can help to contribute to both climate change mitigation and climate change adaptation. Climate-smart agriculture has emerged as a solution to address the multiple challenges of climate change and food security by sustainably increasing productivity, enhancing resilience and reducing greenhouse gas emissions. To date, there is limited scholarly evidence on what constitutes climate-smart agriculture, and how it is framed globally and practiced by smallholder farming communities. This research helps to bridge this gap by analysing the international discourse around climate-smart agriculture, and providing local empirical evidence derived from smallholder farming communities in the Philippines and Timor-Leste. At the broad level, this research aims to identify how climate-smart agriculture within community-based adaptation programs is contributing to the integration of mitigation and adaptation responses to climate change. Drawing from political ecology and climate change (adaptation and mitigation sciences) theories, the research explains how socio-institutional factors – inequality, unequal power relations and social injustice – influence climate-smart agriculture. The theoretical arguments are illustrated with empirical case studies of smallholder farmers and civil society organisations in the two case studies. Using mixed qualitative methods and descriptive analysis of over 150 semi-structured interviews, focus group discussions and participant observation, the research examines climate-smart agriculture practices across three broad categories: vulnerability of smallholder farmers (socioeconomic factors), synergistic relationships (adaptation, mitigation and food security) and governance (socio-institutional determinants). This research argues that mitigation and adaptation interventions are climate-smart for smallholder farmers when they directly address local climate risks, support a combination of adaptation, food security and livelihood strategies, and empower at-risk and marginalised populations. Results indicate that climate-smart agriculture in the Philippines and Timor-Leste are characterised and influenced by multiple socio-institutional factors. The increasing burden of loss and damage as a result of extreme climate events subject women to migration, increased discrimination, loss of customary rights to land, resource poverty and food insecurity. In terms of farming practices implemented by smallholder farmers, most adaptation actions were found to have corresponding positive mitigation, food security and livelihood co-benefits. At the community level, climate-smart interventions are highly location-specific, technically rigorous, involve knowledge-intensive processes, and are influenced by the finance and capacities of local farming communities and implementing partners. Furthermore, of relevance at the global level, this research finds that there is a growing divide between how developed and developing countries frame solutions to the impacts of climate change on agriculture despite agriculture featuring prominently in the United Nations Framework Convention on Climate Change negotiations. Such a divide is limiting the recognition of solutions that integrate mitigation and adaptation opportunities. The insights from the Philippines and Timor-Leste make a compelling case for joint adaptation and mitigation actions in the agriculture sector across three broad policy frontiers. First, implementation of climate-smart agriculture will require participatory platforms that have a focus on livelihood and income opportunities for smallholder farmers. Second, policies and institutions on agriculture, agrarian reform, land use and climate change should mainstream both adaptation and mitigation outcomes using local plans and community level programs. Third, partnerships with community-based organisations and local governments are pivotal to coordinating services with farmers, providing an array of agriculture and climate services generating new knowledge and implementing climate-smart farming solutions.

The way forward: An agroecological perspective for Climate-Smart Agriculture

When and where are livestock climate-smart? A spatial-temporal framework for comparing the climate change and food security synergies and tradeoffs of Sub-Saharan African livestock systems

Climate change presents a significant threat to humanity. It affects agriculture, food supply, and economic development. Urban agriculture (UA) is an alternate climate-smart approach to enhancing food and income security. The climate-smart agriculture (CSA) concept promises to lessen the effects of climate change. Nuanced research is critical to warrant food and income security. This review paper synthesises evidence through a systematic literature search to analyse the implications of CSA practices and climate adaptation strategies for food and income prospects. We also employed bibliometric analysis to show emerging trends and identify knowledge gaps in the ongoing topical discourse. The review elucidates insights into how CSA practices boost urban food production, accessibility, and dietary diversity, ultimately enhancing urban farmers’ food security. The economic benefits of CSA and climate adaptation strategies highlight that UA is vital for improving urban farmers’ income. Despite the opportunities created by UA, the review recognises the critical challenges and trade-offs that call for transforming UA to safeguard food and income security in the face of increasing climate change. The review calls for an all-round UA transformation encompassing urban community-based efforts, capacity building, and policy support mechanisms aimed at advancing climate-resilient UA and ensuring food and income security in an ever-changing environment.

Climate-Smart agriculture and its impact on food security have been topical issues in policy and food security discusses by successive governments in Nigeria however, the extent of its awareness among the farmers as a food insecurity mitigation measure has not been adequately represented in contemporary local literature hence the need for this research to ascertain the extent of awareness through: an examination of literary works by scholars in the field, assessing the extent of climate-smart procedures in agriculture and suggest where possible ideas to enhance its adoption. The study therefore evaluated secondary data and studies on the impacts of climate change on agriculture and how it can be mitigated through the adoption of climate smart approaches. Climate-Smart Agriculture is an emerging agricultural strategy initiated to tackle the consequences of climate change in food security and sustain agriculture. It involves the combination of approaches in the management of agricultural lands, forests, fisheries and livestock. The study in this regard took a holistic view of the adoption of climate smart agriculture by the farmers, its benefits and approaches and considered objectives such as accessing and assessing other scholars works and views on climate smart agricultural practices utilized by rural farmers in parts of Nigeria, discussing climate smart agriculture and food security, deliberating on climate smart agriculture and resource use efficiency and, viewing the constraining factors hampering the adoption of Climate Smart Agricultural practices in Nigeria. This is because climate change presently is one of the challenges and problems facing the world and an important factor in agricultural productivity. Variations in climatic factors will have ripple effects on crop yield and animal production. Farmers may have been facing weather variability and uncertainty patterns, however, the increasing pace of these uncertainties caused by climate change exacerbate food insecurity and hunger incidences and will require some degree of flexibility and rapid response capacity that climate smart agriculture offers. Building resilience in agricultural and farming practices will reduce the risk of food insecurity outside increasing the adaptive capacity and coping capabilities of the farmers.

Given its heavy reliance on rainfed agriculture and projected climatic and weather changes, SSA faces multidimensional challenges in ensuring food and nutrition security as well as preserving its ecosystems. In this regard, climate-smart agriculture (CSA) can play an important role in addressing the interlinked challenges of food security and climate change.\nCSA practices aim to achieve three closely related objectives: sustainably increase agricultural productivity, adapt to climate change, and mitigate greenhouse gas (GHG) emissions. The CSA objectives directly contribute to achieving the 2014 Malabo Declaration goals, which include commitments to (1) end hunger in Africa by 2025, (2) halve poverty by 2025 through inclusive agricultural growth and transformation, and (3) enhance the resilience of livelihoods and production systems to climate variability and other related risks. These linkages underscore the importance of including CSA in country and regional plans to achieve overarching development objectives in Africa, in particular food security and poverty reduction.\nThe 2016 Annual Trends and Outlook Report (ATOR) examines the contribution of CSA to meeting Malabo Declaration goals by taking stock of current knowledge on the effects of climate change, reviewing existing evidence of the effectiveness of various CSA strategies, and discussing examples of CSA-based practices and tools for developing evidence-based policies and programs.

Climate-smart agriculture and food security in climate-vulnerable coastal areas of Bangladesh

Extant systematic literature reviews on the topic of climate smart agriculture (CSA) have mainly focused on two issues: reviewing framing of the CSA discourse in the academic and policy literature; and policy initiatives in the Global South that enhance the adoption of climate‐smart agricultural practices. Yet, there is little systematic investigation into how international organizations can help smallholder farmers manage agricultural systems to respond to climate change. Analyzing these organization's priorities and highlighting their knowledge gaps are crucial for designing future pathways of CSA. We intend to use this article to identify overarching CSA themes that can guide large international organizations to focus their CSA agenda in the hope of achieving goals associated with food security and sustainable intensification. We specifically ask the following question:How have the key CSA topics and themes emerged in the gray literature of international organizations between 2010 and 2020?We adopted a topic modeling approach to identify how six international organizations engaged with several topics related to CSA. Following the Latent Dirichlet Allocation (LDA) approach, we identified eight topics in the documents, representing four overarching themes: gender research, weather and climate, CSA management and food security. We found that there is insufficient discussion on the issues relating to governance measures and gender mainstreaming, with a larger focus on techno‐managerial measures of CSA. We conclude that research and training related to CSA must offer opportunities for marginalized and disproportionately vulnerable populations to participate and raise their voices and share innovative ideas at different levels of governance.This article is categorized under:Climate and Development > Social Justice and the Politics of DevelopmentVulnerability and Adaptation to Climate Change > Institutions for Adaptation

The current state of poverty in Nigeria is alarming and climate change threatens food security and increases poverty directly and indirectly. This research established a link that exists between climate smart agricultural practices and poverty status of small household farmers in North-West geopolitical zone of Nigeria; and based on this, examined climate smart agricultural practices and poverty status of small holder farming households in the zone. The specific objective of the study was to determine factors influencing indicators of climate smart agricultural practices on crop enterprise in the study area. Multi-stage, purposive and random sampling techniques were used to select three hundred (300) farming households in the study area, and using a set of pre-tested structured questionnaires, relevant data were collected. The study employed Ordinary Least Square (OLS), regression models to ascertain the objective. The regression analysis of maize enterprise shows that age, gender, marital status and household size were significant (p < 0.10), with age positively significant inferring that a unit increase in age will result in corresponding increase in the practice of climate smart agriculture for maize enterprise by 0.0264; also, the results showed that many more male farmers used climate smart agriculture in the maize enterprise than their female counterparts by 0.6001. Education, housing materials, lack of time and State option were significant (p < 0.01). The study concludes that crop production is greatly influenced by climate Smart Agriculture in the study area. The results suggest that those who had informal education (Arabic education) had significantly lower indices of climate smart agriculture for maize production than their counterparts who had formal education primary, secondary and tertiary. Housing material was also negatively significant (p < 0.01), meaning that the farmers with mud/thatched and mud/zinc houses had significantly lower usage of climate smart agriculture in the production of maize when compare with those with brick/zinc and concrete block zinc houses. The study concludes that socio economic variables influenced climate Smart Agriculture in the study area. It therefore recommends that women be encouraged to develop interest in climate smart agricultural farming activities through women empowerment programmes instituted by government and private bodies because men dominate the climate smart agricultural practices in the study area; Government, Non-Governmental Organizations and farmer associations should create a conducive learning environment to encourage the farmers of climate smart agriculture in the study area to embrace formal education which can improve their performance rapidly; and finally, policy on informal education should be enriched and developed in the curriculum to meet the current climate smart agricultural challenges.

Climate Smart Agriculture (CSA) is a strategy aimed at lowering greenhouse gas emissions, strengthen climate change resilience, raising crop production and incomes significantly. In a variety of agro-ecological zones, the implementation of climate smart agriculture methods has significantly improved the availability of food, adaptability to fluctuations in the climate, and emissions reduction. One of the key benefits of CSA is its ability to improve agricultural productivity and stabilize food security, particularly for small-scale farmers in developing nations who are most vulnerable to climate change. By integrating sustainable techniques such as conservation agriculture, crop diversification, and agroforestry, CSA helps ensure stable yields, even amid erratic weather patterns. Enhanced soil fertility, enhanced irrigation practices and the use of varieties of crops that are climate resilient all contribute to sustained productivity, mitigating the risks of crop failure and food shortages. CSA also strengthens agricultural systems' resilience to climate impacts by promoting practices like zero tillage, residue management, and efficient irrigation, which improve soil health and water retention, making crops more resistant to droughts and floods. In addition to boosting resilience, CSA contributes to climate change mitigation by reducing agriculture's carbon footprint. Precision farming, organic agriculture, and other low-emission practices help curb greenhouse gas emissions from farming activities. Mobile technology is also emerging as a key driver of CSA by providing real-time information, decision-making support, and access to essential resources, further enhancing the adaptability and sustainability of farming systems. The significance of CSA as a strategic solution to the threats that climate change poses to food security and agricultural sustainability is being more widely acknowledged by governments. As a result, numerous initiatives have been launched at national, regional, and international levels to encourage the widespread adoption of CSA practices. In order to achieve sustainable agricultural development and ensure food security in the face of climate change, CSA must be scaled up around the world.

Impact of adoption of climate-smart agriculture on food security in the tropical moist montane ecosystem: The case of Geshy watershed, Southwest Ethiopia

** The paper is based on the study carried out by the author for FAO (Food and Agriculture Organization) and FANRPAN (Food, Agriculture and Natural Resources Policy Analysis Network) as a consultant.&#x0D; Based on the projection on population growth and food consumption pattern in developing countries, there is likely to be a deficit in the food production by the year&#x0D; 2050. Africa’s population has just passed 1 billion and it is expected to double by the year 2050 (FAO 2012) According to FAO, Sub Saharan Africa, Uganda inclusive, is the region that has the highest proportion of poor and undernourished people in Africa (FAO,2011a). Agricultural production will, therefore have to increase by at least 70% in order to ensure that the food demands are met.&#x0D; Meeting the food demands of a growing population is already a formidable task for agricultural sector of many developing nations like Uganda but this will be further exacerbated by climate change. Largely due to climate change, agricultural productivity is likely to decrease. Similarly, the stability of production and incomes are likely to change. This trend may be even worse in countries which are already experiencing food insecurity (FAO 2012)&#x0D; The important implication of this is that for Uganda, policy makers will be faced with an even greater challenge to ensure that agriculture contributes more in addressing food security issues, development and climate change (adaptation and mitigation). In other words, agriculture in Uganda must undergo major and significant transformation in order to address the challenges likely to be faced in achieving food security and responding to climate change. Put in another way, in order to stabilize output and income, production systems must become more resilient or more capable of performing well in the face of disruptive events. This requires transformation in the management of natural resources and higher efficiency in the use of these resources and inputs for production. &#x0D; According to FAO, approaches that seek to maximize the benefits and minimize the trade-offs across the multiple objectives, often associated with agricultural sector, require more integrated and coordinated planning, policies and institutional arrangements as well as financing and investments. Such approaches and related enabling requirements are referred to by FAO as climate smart agriculture. Climate Smart Agriculture (CSA) is thus a way to ensure the achievements of future food security under climate change. CSA encompasses sustainable agriculture and it includes the need for adaptation and the potential for mitigation with associated technical, policy and financing implications.&#x0D; This scoping study attempts to review and examine the current production practices as it relates to CSA in Uganda. The study also seeks to conduct comprehensive reviews of the existing policies, analyze gaps and identify relevant policy recommendations.
