Assessing whether such trends threaten farmers' long-term adaptive capacity requires a thorough understanding of changes in their crop portfolios, identification of the drivers of change, and the implications such changes have for local nutrition and food production. We reviewed the available literature on farmers' reports of climate-driven crop changes. Small-scale farmers tend to adopt water-demanding crops, even in areas where models predict that reduced rainfall will reduce yields. The adoption of horticultural cash-crops combined with the abandonment of subsistence cereals modifies farmers' nutritional inputs in terms of calories and nutrients, potentially undermining their food security. Farmers' knowledge contributes to understand trends in crop diversity and support the design of strategies for adaptation to climate change. specialized AFRIQUE DE L'EST AFRIQUE DE L'OUEST AFRIQUE DU SUD ASIE DU SUD EST INDE NEPAL 098AGRIC 021CLIMAT01 Reckien D. ed. edt IRD Vaughan C. ed. edt IRD Shwom R. ed. edt IRD 51 15-23 2021 1877-3435 https://www.documentation.ird.fr/hor/fdi:010082003 10.1016/j.cosust.2021.01.006 1877-3435 [F B010082003] https://www.documentation.ird.fr/hor/fdi:010082003 https://www.documentation.ird.fr/intranet/publi/2021-06/010082003.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2021-06-21 2025-02-24 fdi:010082003 fre
