International cooperation is vital to share knowledge, technologies, and best practices across borders. Collaborative efforts can help mitigate the impacts of climate change on maize production and promote the equitable transformation of food systems (Grote et al., 2021). Aligning maize agro-food systems with the Sustainable Development Goals (SDGs) can further enhance food and nutrition security globally (Guo et al., 2019). 8.3 Application of cutting-edge technologies in maize production The application of cutting-edge technologies in maize production is pivotal for achieving sustainable agriculture. The use of advanced genome editing tools and synthetic biology approaches can accelerate the development of maize varieties that are resilient to biotic and abiotic stresses. Additionally, the integration of molecular and genetic mechanisms into agricultural practices can improve crop yields and ensure food security (Tyczewska et al., 2018). Optimizing agricultural strategies, such as adjusting sowing dates and selecting appropriate cultivars, can significantly boost maize yields under different climate scenarios (Shiferaw et al., 2011). These technological advancements must be supported by robust research and development frameworks to maximize their potential benefits. 9 Concluding Remarks Maize plays a critical role in global food security, serving as a staple crop for billions of people worldwide. However, its production faces numerous challenges, including pest infestations, climate change, and socio-economic factors. Postharvest losses due to insect pests like the maize weevil and large grain borer can reach up to 40% in developing countries, highlighting the need for insect-resistant varieties and improved storage solutions. Additionally, the maize agro-food system's alignment with the Sustainable Development Goals (SDGs) underscores its importance in ensuring food and nutrition security. In regions like Central Malawi, maize production is hindered by factors such as climate change, land degradation, and high input costs, necessitating policy reviews and sustainable practices to enhance productivity. Conservation agriculture has shown potential in increasing maize yields and nutrient content, although it may exacerbate certain nutrient deficiencies. Climate change poses a significant threat to maize yields, with projections indicating substantial yield reductions under increased global temperatures. Furthermore, emerging diseases like Maize Lethal Necrosis (MLN) present additional risks to maize-based food security in Sub-Saharan Africa. Continued research is essential to address the multifaceted challenges facing maize production and its role in global food security. Developing insect-resistant maize varieties and improving storage techniques can significantly reduce postharvest losses. Research into the impacts of climate change on maize yields and the efficacy of adaptation methods is crucial for mitigating future risks. Additionally, exploring the genetic diversity of maize and enhancing its nutritional profile through biofortification can improve food and nutrition security. Understanding the effects of conservation agriculture on nutrient yields and addressing potential nutrient deficiencies will be vital for sustainable agricultural practices. Collaborative efforts to manage emerging diseases like MLN and improve disease-resistant germplasm are also critical. Overall, a coordinated approach to research and knowledge sharing can enhance the resilience and productivity of maize, ensuring its continued contribution to global food security. Maize remains a cornerstone of global food security, providing essential calories and nutrients to billions of people. However, its production is increasingly threatened by biotic and abiotic stresses, socio-economic challenges, and climate change. Addressing these issues requires a multifaceted approach, including the development of resilient maize varieties, sustainable agricultural practices, and effective policy interventions. Continued research and innovation are paramount to overcoming these challenges and ensuring that maize can meet the growing food demands of the future. By leveraging scientific advancements and fostering international collaboration, we can enhance the sustainability and resilience of maize production, securing its role in global food security for generations to come.
