For a dissertation for a  BSc in Development Studies for this topic: The role of Climate Resilience Livelihoods for Sustainable Food and Income Security: A Case Study of  Zaka District (2020-2024). Re-write the following background of the study using the funnel approach i.e. start from international to regional to the local.
The impacts of climate change on agriculture and rural communities are becoming increasingly evident, posing significant challenges to food and income security. Zaka District in Masvingo Province, Zimbabwe is particularly vulnerable to these climate-related risks, with local communities experiencing adverse effects on their livelihoods. This dissertation aims to investigate the role of climate resilience livelihoods in promoting sustainable food and income security in Zaka District over a four-year period (2020-2024).
The district in our study is located in the Masvingo Province of Zimbabwe, a landlocked country in Southern Africa. The district covers an area of approximately 2,800 square kilometers and has a population of over 200,000 people, with the majority living in rural areas. (Masvingo Census Report). The district is characterized by a semi-arid climate, with an average annual rainfall of 700-800 mm.(Zimbabwe Meteorological Services Department).The main economic activity in this District is rain-fed agriculture, with smallholder farmers cultivating crops such as maize, sorghum, millet, and groundnuts.(Zaka District Agriculture Office, 2020).
The area is a predominantly rural area in Zimbabwe that heavily relies on rain-fed agriculture, making it highly vulnerable to the impacts of climate change. The district has experienced a series of droughts in recent years, with the most severe being the El Niño-induced drought in 2015-2016, which left an estimated 4.1 million people in need of food assistance (FAO, 2016). These recurring shocks have not only resulted in decreased agricultural productivity but have also led to increased food insecurity and poverty among rural households.
The vulnerability of this district to climate change is further exacerbated by various factors such as deforestation, land degradation, and overexploitation of natural resources (Masvingo Provincial Environmental Impact Assessment Report, 2021). These practices have contributed to the degradation of the district's natural environment, making it more susceptible to the impacts of climate change. This is evident in the increased frequency and intensity of droughts, floods, and extreme weather events in the district (Zimbabwe Climate Change Impacts Assessment Report, 2022). These events have had a significant impact on the district's agricultural sector, leading to decreased productivity and loss of livelihoods for local communities.
Moreover, its vulnerability to climate change is compounded by its high poverty levels and limited access to resources and information. The majority of households in the district rely on subsistence agriculture for their livelihoods, making them highly dependent on natural resources. As a result, any changes in weather patterns or extreme events can have a devastating impact on their food and income security. This vulnerability is further exacerbated by limited access to information and resources to help communities adapt to the changing climate (Zaka District Climate Vulnerability Assessment, 2023).The impacts of climate change on agriculture in Zaka District are significant. According to a study by the Food and Agriculture Organization (FAO), climate change is projected to reduce maize yields by up to 20% by 2050 in Zimbabwe. This is a major concern for the district, where maize is the staple food and a major source of income for smallholder farmers. The decrease in agricultural productivity has also led to increased food and income insecurity, with a high prevalence of malnutrition and undernourishment among children and the local population. (Zimbabwe Climate Change Adaptation and Mitigation Strategy, 2020). 
The role of climate resilience livelihoods has become increasingly important in ensuring sustainable food and income security in the area. This is particularly relevant in the current context of climate change, which has had a significant impact on the income levels of households in the district. The decrease in agricultural productivity due to changing weather patterns and extreme weather events has highlighted the need for communities to adopt more resilient livelihood strategies. This dissertation aims to explore the specific challenges faced by households in Zaka District and assess the effectiveness of climate resilience livelihoods in promoting sustainable food and income security from 2020 to 2024. By examining the experiences and perspectives of local communities, this study will contribute to a deeper understanding of the role of climate resilience in addressing poverty and promoting sustainable development in the district. 
In response to these challenges, the government of Zimbabwe, in collaboration with development partners, has implemented various interventions to address the impacts of climate change in Zaka District. These include the promotion of climate-smart agriculture, sustainable land management practices, and the provision of drought-resistant crop varieties. Non-governmental organizations have also assisted heavily in trying to address this issue through the implementation of programs like the USAID-funded Takunda program in Mutare and Masvingo including, Zaka, which seeks to build the resilience of low-income people who may be chronically affected by climatic and economic shocks and by working to achieve sustainable and equitable income from agriculture production; improving off- and non-farm livelihoods, and creating more opportunities for income-generating activities. (FANRPAN, 2023). However, these interventions have not been conclusively effective in addressing the underlying causes of vulnerability and building resilience among local communities.
Therefore, there is a need for a deeper understanding of the role of climate-resilient livelihoods in addressing food and income security challenges in the study District. This study aims to fill this gap by examining the current livelihood strategies adopted by communities in the district and their effectiveness in mitigating the impacts of climate change. The findings of this study will provide valuable insights for policymakers and development practitioners in designing and implementing sustainable interventions to enhance resilience and promote sustainable development in vulnerable regions like Zaka, Masvingo District.
