Food security remains a challenge in South Asia since GDP per capita averaged US$ 2,308 in 2023, the secondlowest among all regions as per the World Bank’s World Development Indicators. Moreover, this region holds the largest number of undernourished people (281 million or 13 percent of the population in 2023) according to the Food and Agriculture Organization. Simultaneously, sustainability of agricultural production with a changing climate has emerged as an additional challenge in recent times. For instance, South Asia’s renewable internal freshwater resource per capita has fallen from over 3000 to about 1000 cubic meters between 1961 and 2020, accompanied by a 68 percent decline in arable land (hectares) per person (World Development Indicators).
