The convergence of anthropogenic climate change and global food security demands represents one of the most pressing challenges of the 21st century. Horticulture—encompassing fruit and vegetable production—is uniquely vulnerable to climatic perturbations due to the biological sensitivity of horticultural crops to temperature extremes, irregular precipitation, and shifting pest dynamics. Simultaneously, horticultural systems offer considerable potential for adaptation and mitigation through diversified, resource-efficient production models. This narrative review synthesises emerging evidence on climate-smart strategies for sustainable fruit and vegetable production, drawing on peer-reviewed literature and authoritative international reports published predominantly between 2000 and 2026. Literature searches were conducted using multiple academic databases, including Web of Science, Scopus, Google Scholar, PubMed, AGRIS (the agricultural science and technology information database maintained by the Food and Agriculture Organization of the United Nations), CAB Abstracts, and the CGIAR research portal. The review examines the multidimensional impacts of climate change on horticultural systems and evaluates a suite of responses spanning crop genetic improvement, precision irrigation, soil carbon management, protected agriculture, agroforestry, digital technologies, and policy frameworks. Evidence indicates that no single strategy is sufficient; rather, transformative change requires integrated, context-specific combinations of adaptation and mitigation interventions supported by enabling policy environments. The review identifies key knowledge gaps and advocates for greater investment in transdisciplinary research, smallholder inclusion, and digital innovation to accelerate the transition to climate-smart horticulture globally.

Drought constitutes one of the most pervasive abiotic constraints limiting global crop productivity, with its frequency and intensity projected to increase substantially under ongoing climate change. This narrative review synthesises contemporary evidence on the genetic, physiological, and agronomic dimensions of drought resilience in major food crops, drawing on peer-reviewed literature published primarily between 2000 and 2026. Physiologically, drought impairs stomatal conductance, suppresses photosynthetic carbon assimilation, disturbs osmotic equilibrium, and restricts root-mediated water acquisition, with reproductive stages being disproportionately vulnerable. At the genetic level, the deployment of quantitative trait loci (QTL) mapping, transcription-factor engineering, CRISPR-Cas9 genome editing, and the overexpression of stress-responsive functional genes has opened novel avenues for enhancing tolerance without compromising yield potential. Breeding programmes have increasingly integrated marker-assisted selection (MAS) and genomic selection to accelerate genetic gain, whilst high-throughput phenotyping platforms now enable rapid assessment of drought-adaptive traits at a population scale. Agronomic strategies, including deficit irrigation, conservation tillage, intercropping, and application of plant growth-promoting rhizobacteria (PGPR), provide complementary levers for sustaining productivity under water-limited conditions. Emerging integrative approaches that combine multi-omics, digital precision agriculture, and policy-enabled climate-smart frameworks are highlighted as critical pathways for translating laboratory and field insights into scalable solutions. The review identifies persistent knowledge gaps—including the limited translation of genomic advances to smallholder contexts and the underexplored potential of microbiome engineering—and calls for a convergence of disciplinary expertise, equitable technology transfer, and coherent policy support to achieve drought-resilient food systems globally.
