Abstract: Agriculture and food security in arid and semi-arid (ASA) regions face challenges due to hydroclimatic stresses, such as heat waves, water scarcity, water quality degradation, and poor soil conditions. Rapid urbanisation and population growth further exacerbate the situation by diverting freshwater away. Small-scale farmers, in particular, are affected severely, and are often compelled to use marginal-quality water due to a lack of alternatives. Farmers in ASA regions often utilise a mix of river water and saline groundwater for irrigation, and are increasingly shifting to crops that are more tolerant of heat, drought, and salinity. This chapter explores the intricate interaction between water systems and agricultural practices in ASA regions, and explores potential solutions. Addressing these challenges requires a holistic approach that aligns with various Sustainable Development Goals (SDGs), specifically SDG 2, SDG 6, SDG 13, and SDG 15, to ensure a sustainable and resilient future.
