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

Sustainable farming systems require crop protection strategies that conserve biodiversity, protect human health, and maintain economic viability while limiting yield losses from insects, mites, nematodes, and plant pathogens. Integrated pest and disease management offers such a pathway by replacing single-input thinking with a systems approach that prioritises prevention, ecological regulation, monitoring, and carefully targeted interventions. This review synthesises the contemporary evidence on how integrated management can be designed and implemented across diverse farming systems. It traces the conceptual evolution from the integrated control paradigm to modern whole-system approaches, and then examines the ecological and epidemiological processes that determine pest outbreaks, disease epidemics, and resistance evolution. Particular attention is given to preventive design through crop diversification, habitat manipulation, soil health management, resistant cultivars, and clean planting material; to advances in monitoring through field scouting, forecasting, imaging, molecular diagnostics, and digital surveillance; and to tactical interventions including biological control, biopesticides, selective chemical inputs, and emerging RNA-based tools. The literature underpinning this review was identified through structured searches of major scientific databases. The review argues that sustainable crop protection depends less on substituting one product for another than on combining agronomic, biological, technological, and institutional measures in a coherent decision framework. It also shows that successful integration is shaped by production context, from broadacre arable systems and protected horticulture to smallholder and organic farming. Climate change, global trade, and accelerating resistance evolution make this integration more urgent, but adoption continues to be constrained by fragmented advisory systems, weak incentives, and uneven access to knowledge-intensive tools. The paper concludes that the future of integrated pest and disease management lies in redesigning farming systems around resilience, supported by better diagnostics, stronger ecological literacy, and policy environments that reward long-term prevention rather than routine curative input use.
