This document discusses increasing agricultural water productivity. It notes that with population growth and increasing water demand, more food must be produced using less water. Improving water productivity through strategies like water savings and more efficient uses can help meet this challenge. The document then outlines various ways to increase water productivity, such as for crops, livestock, fisheries, and integrated systems. It also discusses how increased water productivity can help reduce poverty through improved food security, employment, and income opportunities.

4. Introduction
 Producing enough food and generating
adequate income in the developing world to
better feed the poor and reduce the number
of those suffering will be a great challenge.
 This challenge is likely to intensify, with a
global population that is projected to
increase to 7.8 billion in 2025, putting even
greater pressure on world food security,
especially in developing countries, where
more than 80% of the population increase is
expected to occur.
 Irrigated agriculture has
been an important contributor to the expansion
of national and world food supplies
since the 1960s and is expected to play a
major role in feeding the growing world
population.

5.  However, irrigation accounts
for about 72% of global and 90%
of developing-country water withdrawals.
 With growing irrigation-water demand
and increasing competition across
water-using sectors, the world now
faces a challenge to produce more
food with less water.
 This goal will be realistic only if
appropriate strategies are found
for water savings and for more
Efficient water uses in agriculture.

6.  Water Productivity is defined as
The ratio of net benefits from Crop,
forest, fishery, livestock , and mixed
agricultural system to the amount
of water required to produce those
benefits.
Water Productivity ?

7. There are important reasons to improve agricultural
water productivity:
 To meet the rising demand for food from a growing,
and increasingly urbanized population,
in light of water scarcity.
 To respond to pressures to reallocate water from agriculture
to cities and to ensure that water is available for environmental
uses.
 To contribute to poverty reduction and economic growth.
For the rural poor more productive use of water can mean
better nutrition for families.
Why is it important?

8.  Water productivity analysis can be applied to
crops, livestock, tree plantations, fisheries,
and mixed systems at selected scales—crop
or animal, field or farm, irrigation system, and
basin or landscape, with interacting
ecosystems
A framework for water productivity

9. 1.Increasing the water
productivity of livestock
 Globally, livestock production accounts for some 20%
of agricultural evapotranspiration, and this proportion
could grow with the increasing consumption of animal
products.

10. 2.Increasing water
productivity in fisheries and
aquaculture
 As with livestock, there is considerable scope for
better integrating fisheries and aquaculture
with water management systems to improve
water productivity and reduce poverty

11.  Reducing or limiting water withdrawals from rivers
and groundwater through water-saving practices
and demand management remains an important
strategy to control water resources, limit damage
to aquatic ecosystems, and in some cases release
water from agriculture to other uses.
3.Improving the water
productivity of water
deliveries

12.  Designing and managing agricultural water
for multiple uses—drinking water, industries,
livestock, fisheries—can raise the social and
economic productivity of water in water
management systems
Applying integrated
approaches to increasing the
value per unit
of water

13.  Water productivity improvement can provide
two pathways to poverty alleviation. First,
targeted water interventions can enable poor
and marginalized people to gain access to water
and use it more effectively. Second, across-the-
board increases in water productivity may
benefit poor people through multiplier effects on
food security, employment, and income.
