Assessing the Impact of Climate Change on Agricultural Productivity in Developing Countries: A Case Study of Smallholder Farmers in Nigeria

Thesis Abstract

Abstract
Climate change poses a significant threat to agricultural productivity, particularly in developing countries where smallholder farmers are highly vulnerable. This thesis investigates the impact of climate change on agricultural productivity in Nigeria, focusing on smallholder farmers. The study explores the challenges faced by smallholder farmers in adapting to changing climate patterns and assesses the implications for food security and rural livelihoods. A mixed-methods approach was employed, combining quantitative analysis of agricultural data with qualitative interviews and surveys conducted among smallholder farmers in Nigeria. The research findings reveal that smallholder farmers in Nigeria are experiencing adverse effects of climate change, including erratic rainfall patterns, prolonged droughts, and increased pest infestations. These climatic changes have resulted in reduced crop yields, livestock losses, and decreased income for farmers. Limited access to resources, inadequate infrastructure, and poor extension services further exacerbate the vulnerability of smallholder farmers to climate change impacts. Despite these challenges, the study identifies various adaptation strategies employed by smallholder farmers to mitigate the effects of climate change on agricultural productivity. These strategies include crop diversification, water harvesting techniques, agroforestry practices, and the use of climate-resilient crop varieties. However, the adoption of these adaptation measures is constrained by factors such as financial constraints, lack of technical knowledge, and inadequate government support. The implications of climate change on agricultural productivity extend beyond the farm level, affecting food security, rural livelihoods, and overall economic development in Nigeria. Addressing the challenges posed by climate change requires a multi-faceted approach that integrates climate-smart agriculture practices, improved access to markets, and enhanced support for smallholder farmers. In conclusion, this thesis underscores the urgent need for climate change adaptation strategies tailored to the specific needs of smallholder farmers in Nigeria. By enhancing resilience and promoting sustainable agricultural practices, policymakers, researchers, and development practitioners can contribute to improving the livelihoods of smallholder farmers and ensuring food security in the face of a changing climate.
