– making a beneficial relation more sustainable
Globally, irrigated agriculture is the largest
abstractor and predominant consumer of
groundwater resources, with important
groundwater-dependent agroeconomies having
widely evolved. But in many arid and droughtprone
areas, unconstrained use is causing
serious aquifer depletion and environmental
degradation, and cropping practices also exert
a major influence on groundwater recharge
and quality. The interactions between
agricultural irrigation, surface water and
groundwater resources are often very close –
such that active cross-sector dialogue and
integrated vision are also needed to promote
sustainable land and water management. Clear
policy guidance and focused local action are
required to make better use of groundwater
reserves for drought mitigation and climatechange
adaptation. To be effective policies
must be tailored to local hydrogeological
settings and agroeconomic realities, and their
implementation will require appropriate
‘institutional arrangements’ (with a clear focal
point and statutory power for groundwater
management), full involvement of the farming
community and more alignment of agricultural
development goals with groundwater
availability.
