Climate-Adaptive Farming: Strategies for Food Security and Adaptation Models Amid Rising Droughts and Population Pressures

Global food systems face an unprecedented convergence of interconnected stressors: accelerating climate change, rapid biodiversity loss, escalating demographic pressure, entrenched socioeconomic inequalities, geopolitical instability, and the deepening ecological overshoot of planetary boundaries. Without deliberate, large-scale structural transformation, food insecurity is projected to intensify substantially across all world regions by 2050, with the most severe consequences concentrated in tropical and sub-tropical developing economies where adaptive capacity remains most constrained. This review synthesises current scientific understanding of the pathways, enabling conditions, and barriers associated with constructing climate-resilient food systems by 2050, drawing on peer-reviewed literature published between 2000 and 2026 and authoritative intergovernmental reports. The paper examines the biophysical and socioeconomic dimensions of climate risk to food systems; evaluates emerging technological, agroecological, digital, and governance innovations; identifies critical knowledge gaps related to systems-level integration, equity, dietary transition, and maladaptation risk; and proposes an integrated science–policy roadmap that places transformative adaptation and mitigation at the centre of food system governance. The synthesis reveals that piecemeal, sector-by-sector approaches are fundamentally insufficient to meet the dual challenge of food security and planetary sustainability: only coherent, cross-scalar, politically committed, and equity-centred action can deliver the systemic change required. Key priority areas include scaling investment in climate-smart and agroecological production systems, strengthening the integration of indigenous and local knowledge, reforming environmentally distorting agricultural subsidy structures, accelerating equitable digital agri-food transitions, and embedding food system resilience within legally binding international climate commitments and national development planning frameworks.
