Evaluation of drought-tolerant maize varieties for improved yield and resilience under climate change

Project Abstract

Evaluation of Drought-Tolerant Maize Varieties for Improved Yield and Resilience under Climate Change This project aims to evaluate the performance and resilience of drought-tolerant maize varieties under varying climate conditions, with the ultimate goal of enhancing food security and supporting sustainable agricultural practices. Maize is a staple crop that plays a crucial role in the global food system, providing essential nutrients and calories for millions of people worldwide. However, the increasing frequency and severity of droughts, driven by climate change, poses a significant threat to maize production, particularly in regions already prone to water scarcity. The project will focus on identifying and assessing drought-tolerant maize varieties that can maintain high yields and stability under limited water availability. By evaluating the performance of these varieties across diverse climatic and soil conditions, the research team aims to provide farmers and policymakers with evidence-based recommendations to guide the selection and adoption of resilient maize cultivars. This knowledge will be particularly valuable in regions where climate change is expected to exacerbate the impact of droughts, threatening the livelihoods and food security of smallholder farmers. The research methodology will involve a comprehensive field-based evaluation of selected drought-tolerant maize varieties, including both established and newly developed cultivars. The trials will be conducted in multiple locations, representing a range of climatic conditions and soil characteristics, to assess the varieties' performance under diverse environmental stresses. Detailed data will be collected on parameters such as yield, biomass, drought tolerance indices, and resource use efficiency to provide a robust evaluation of the varieties' resilience and adaptability. In addition to the field trials, the project will also incorporate modeling and simulation approaches to predict the long-term impacts of climate change on maize production and the effectiveness of drought-tolerant varieties. This will enable the research team to develop decision-support tools and guidelines that can assist policymakers and agricultural extension services in planning and implementing climate-smart agricultural strategies. The project's expected outcomes include the identification of superior drought-tolerant maize varieties that can maintain high yields and stability under water-limited conditions. The research findings will be disseminated through peer-reviewed publications, policy briefs, and stakeholder workshops to ensure that the knowledge generated is accessible to a wide range of end-users, including farmers, agronomists, and policymakers. Furthermore, the project will contribute to the broader scientific understanding of plant adaptation mechanisms to drought stress, which can inform the development of innovative breeding and management strategies for other important crops. By addressing the critical challenge of climate change-induced drought and its impact on maize production, this project has the potential to significantly enhance food security, support the livelihoods of smallholder farmers, and promote the long-term sustainability of agricultural systems.
