Agriculture in and around Indian cities is under pressure due to rapid urbanisation and associated land use change, and couples with pressure on already scarce water resources. The major beneficiaries of UA in the larger cities are low-income communiies that make use of the available resources - vacant land, river banks and wastewater - to supplement their meagre incomes. Rainwater is a valuable potential resource, and government attention to rainwater harvesting is growing, but its potential for UA is still poorly understood and documented.
