  How effective are financial mechanisms, such as microinsurance, climate finance, and access to credit, in supporting women in vulnerable rural communities' efforts to adapt to climate change?

  Key finding

  
  Through a case study on the adoption of agricultural technologies in developing countries, this research reveals that financial empowerment can boost farmers' abilities to adapt to climate-resilient agriculture, which may involve the female gender as well. This emphasizes the fact that, when accompanied by targeted policies and education, financial mechanisms go a long way to improve the adaptive capacity of such communities. Findings on gender-sensitive policy support at a localized level combined with access to finance in microinsurance and climate finance are fundamental necessities for empowerment. This directly responds to the sub-question demonstrated within this paper on how such tools, backed up by support from policies as well as educational interventions, work to support and strengthen resilience within vulnerable communities at the local, rural scale.This study is a meta-analysis that is quantitative; it outlines factors influencing the adoption of agricultural technologies in developing countries, particularly focusing on the salient socio-economic and policy-related factors affecting adoption levels and potentially guiding interventions with a focus on climate change adaptation.

  Short summary

  
  A meta-analysis was carried out on the adoption of agricultural technology in developing countries and on findings that pinpoint significant determinants of adoption such as education and land size, access to credit, among others. The review shows that policies and interventions that focus on education, extension services, and secure land tenure significantly improve adoption rates. However, it also calls for localized approaches that consider the socio-economic constraints of the smallholder farmer. The study thus recommends that combining financial mechanisms such as access to credit with education and policy will help strengthen the adaptive capacity of vulnerable rural communities, particularly women.

  What impact do infrastructure improvements, such as climate-resilient housing, water management systems, and renewable energy, have on reducing the vulnerability of marginalized communities?

  Key finding

  
  This study addresses the sub-question of how infrastructure improvement through climate-resilient housing, water management systems, and renewable energy will help reduce the vulnerability of the marginalized communities by exploring the overall role of climate-smart agriculture in smallholder farming. While the review mainly focuses on agricultural practices, it highlights how improved access to infrastructure—such as water management systems and financial mechanisms—can help overcome barriers to adoption and enhance resilience. The study underscores that financial access, better inputs, education, and gender-sensitive policies are crucial to overcoming constraints faced by marginalized groups, particularly women. By addressing these constraints, improvements to infrastructure and practice of CSA would significantly decrease the vulnerability of rural communities with weaker adaptive capacities while enhancing the prospects for more sustainability and resilience within these areas vis-à-vis climate change.

  Crop rotation, agroforestry, and improved water management as CSA (Climate Smart Agriculture) practices increase productivity, income, and environmental sustainability for smallholder farmers, but adoption rates are constrained by financial constraints, lack of access to inputs, and gender inequalities.

  Short summary

  
  CSA can benefit small-scale farmers in terms of increasing yields, income, and environmental performance. But adoption is often limited due to financial, informational, and gender-related barriers. Access to finance, education, and extension services, social networks, and cooperatives can increase adoption rates. There is a need for targeted policies and structural interventions for addressing such challenges and empowering marginalized groups.

  How are education, capacity-building, and skills training programs enabling vulnerable populations to adopt climate-smart agricultural practices or other sustainable livelihood strategies?

  Key finding

  
  This study directly responds to the sub-question by illuminating how programs in education, capacity building, and skills training are foundational in helping susceptible populations embrace climate-smart agriculture practices and strategies for sustainable livelihoods. A systematic review reveals that combined access to education and capacity-building with cooperative structures improves the ability of small holder farmers to be adaptive to changing climate conditions in terms of exchanging knowledge and securing resources. More specifically, agroecology, agroforestry, and cooperative models are recognized as being effective climate-smart practices that increase agricultural productivity, environmental sustainability, and economic outcomes. Moreover, this study underlines the fact that adaptation efforts are only viable when interventions become context-specific and culturally relevant for effective effectiveness. In this context, education and capacity-building programs are important so that vulnerable groups may be facilitated in developing such skills and acquiring such knowledge through which they will enhance their climate change resilience capabilitiesEducation, capacity-building, and skills training programs are essential in enabling vulnerable populations to adopt climate-smart agricultural practices and other sustainable livelihood strategies, thereby enhancing resilience and adaptive capacity.

  Short summary

  
  A systematic review of 94 studies indicates that adaptation to climate change in agriculture through agroecology, agroforestry, and cooperatives is beneficial for smallholder farmers. Access to education, capacity-building programs, and community cooperation have been the most significant factors for such positive outcomes. Such interventions boost adaptive capacity through soil improvement, diversified income generation, and the building of resilience in ecosystems. The  review suggests  that fair decision-making and relevance to local needs or cultural practices would make the adaptation strategies more practical.

• To what extent do policy frameworks and government interventions, such as social safety nets, disaster risk reduction programs, and land tenure reforms, support the adaptive capacity of at-risk communities?

  To what extent do policy frameworks and government interventions, such as social safety nets, disaster risk reduction programs, and land tenure reforms, support the adaptive capacity of at-risk communities?

  Key finding

  This study answers the sub-question by illustrating how policy frameworks and government interventions, such as social safety nets, disaster risk reduction programs, and land tenure reforms, play an important role in enhancing the adaptive capacity of at-risk communities. Systematic reviews identified that perfect adaptation would require localized policies to focus on specific socio-economic conditions, such as agroecology, sustainable agriculture, and pro-environmental agricultural technologies. These interventions improve resilience, particularly when gender-sensitive and inclusive strategies are employed to ensure that resources and decision-making processes are available to marginalized groups, including women. Thus, the findings suggest that well-designed government actions and policy frameworks are essential in empowering vulnerable communities to adapt to climate change.

  The review is based on the synthesis of two studies, which investigate the kind of interventions policy frameworks, government action, and pro-environmental agricultural technologies could have to enhance the vulnerable communities' capacity to adapt to climate change.

  Short summary 

  Two studies reviewed bring out the point that specific agricultural technologies, government actions, and policy frameworks enhance adaptive capacity of vulnerable communities. In analyzing adoption factors of pro-environmental agricultural technologies (PEATs) in China, Xie & Huang (2021) established that socio-demographic and farm structure factors determine and affect the adoption. On how to adapt to climate change, Owen (2020) found that cooperative organizations, agroecology and policies, and structural intervention on how policies and structural intervention enhance resilience in vulnerable areas are essential. The context in both studies calls for attention to context-specific policies and support, gender-sensitive interventions and support, and tailor-made support.

  How effective are partnerships between governments, NGOs, and international organizations in delivering targeted interventions that build climate resilience in the most vulnerable regions?

  Key finding

  
  This study addresses the sub-question by investigating how agroforestry interventions in low- and middle-income countries, supported by partnerships between governments, NGOs, and international organizations, can enhance climate resilience in vulnerable communities. It highlights that agroforestry improvement can focus on soil fertility, biodiversity, and water retention, thus imparting potential benefits for agriculture and ecosystem services. However, such interventions are context-specific and therefore differentially effective for crop yield and income improvements as well as to the more vulnerable groups of the population, notably women. This study draws attention to targeted and inclusive approaches to local conditions and environmental, social, and economic conditions; however, more research is necessary to strengthen the evidence base and make sure that such partnerships work well and in a fair way in building resilience among the most vulnerable populations.

  Low- and middle-income country agroforestry interventions often bring positive impacts to agriculture, ecosystem services, and human well-being although differences abound among contexts and these outcomes tend to depend on, for example, level of income, gender,  or specific regional conditions.

  Short summary

  
  The review of low- and middle-income countries systematically explored agroforestry interventions, which typically saw the integration of trees into either crops or livestock. Integration tends to increase crop yields and soil fertility but often has unclear, mixed effects for income and nutrition, with often detrimental effects on women and other vulnerable groups. In conclusion, there is a need for more targeted and inclusive programs that consider the specific needs of these vulnerable groups. Further research should be emphasized to strengthen the evidence base and understand the full range of impacts of agroforestry on different communities.
