Abstract Today the competition for
scarce water resources in many places is intense. The lack of water in most developing countries, particularly those
in arid and semi-arid regions, is the major constraint to producing food for hundreds of millions of people.
Agriculture is central in meeting this challenge. On the globe, nearly 70% of the available water resources are
allocated to food production and agricultural products but, unfortunately, with enormous water losses exceeding
50%.
To meet the acute freshwater challenges facing humankind over the coming 50 years and to fulfil the food
gap to feed 8-9 billion people, directing all the efforts to improve water use and management in agriculture is now a
must.
The hope lies in closing the gap in agricultural productivity and in realizing the unexplored potential
through water management along with realistic changes in the policy agenda, production techniques and implemented
strategies.
Many promising pathways for raising water productivity are available by adopting proven
agronomic and water management practices. However, despite adequate technologies and management practices,
achieving net gains in water productivity is facing numerous constraints with low adoption rates. The adoption of such
techniques requires an enabling policy and institutional environment that aligns the incentives of producers, resource
managers and society and provides a mechanism for dealing with trade-off.
This paper will examine in detail
the promising pathways to achieving higher water productivity and the major constraints and it will also discuss the
changes needed in the policy agenda and water management strategies highlighting the needed policy action
