Climate change and food security: Adaptation strategies and funding supports

Climate change significantly impacts food security and necessitates substantial funding and adaptation strategies to mitigate these effects. The relationship between increased atmospheric carbon dioxide, altered meteorological processes, and rising global temperatures intensifies vulnerabilities in food supply chains, especially in regions already facing food insecurity. This review examines recent innovations in adapting food security systems to climate-related challenges, highlighting both advancements and persistent obstacles. Innovations include technological advancements such as precision agriculture and climate-resilient crop varieties, which help optimize resource use and enhance crop resilience. Policy frameworks also play a critical role, with measures such as the Common Agricultural Policy of European Union and the Paris Agreement guiding climate-smart agricultural practices. Community-based adaptations, which integrate local knowledge and modern technologies, further contribute to resilience. Despite these efforts, challenges such as financial constraints, technological limitations, policy incoherence, and social inequities hinder effective adaptation. Addressing these challenges requires increased investment, improved infrastructure, coherent policies, and equitable support for vulnerable populations. Ultimately, adaptation is crucial not only for sustaining food security but also for aligning global efforts to mitigate the broader impacts of climate change.
