There is high confidence that a significant share of water-related adaptations is occurring in the agriculture sector. Agriculture accounts for 60-70% of total water withdrawals  and supports the livelihoods of a large majority of people in the developing countries. Within the agriculture sector, there is high confidence in the quality and quantity of evidence of adaptation responses such as improved cultivars and agronomic practices, on-farm irrigation and water management and water and soil moisture conservation, and medium confidence, derived from robust evidence, and medium agreement for other most other adaptation responses . Most of these adaptation case studies are from Asia and Africa, and agriculture is the predominant sector where most of these adaptation responses are being implemented  . However, the sectoral nature of adaptation responses varies across continents. Agriculture is the most important sector in all continents, except Europe and Australasia, where most adaptation occurs in the urban sector  .
