II. The initial challenge
• Climate change impact: reduced flow, severity of
extreme events;
• Demographic pressure – population growth 1.2 – 1.8%
year;
• Land degradation;
• Poor water management;
• Competition between power and irrigation;
• Ongoing restructuring of agrarian farming;
• Instability of market and prices.

11
What we have now?
From one side – scientificscientific:
• Huge scope of decisions, knowledge, recommendations;
• Huge data base in different directions and specifics;
• Forecasts and optimizations;
• Human potential.
From other side - water and land userswater and land users:
• Lack of knowledge;
• Deficiency of experience;
• Weakness of governance;
• Difficulty with approach to data and forecast;
• Absence of ongoing recommendations.

• In 2007, the Foundation was set up land reclamation.
• A state program of reclamation of irrigated lands in the period of 2008 - 2012
years.
• Allocated about $ 500 million.
• Improved reclamation of 1.2 million hectares of irrigated land .
• Reduced the area is strong - and medium saline lands by 81.2 thousand hectares
• Lowered the water table in the area of 365 ha
• Particular attention is paid to the development of water-saving irrigation
technologies, particularly drip irrigation system.
• Total area of the drip irrigation system is approximately 10.0 hectares in 2013 is
planned to 3,5 ha

Soil productivity improvement
LEGUMES
It is well-known that such crops as green gram, Russian bean, and soy bean are the
sources of protein, the deficit of which affects almost half of the world’s population,
according to FAO. However, even in case of provision with the animal protein, the
vegetable protein is an essential easily absorbed element. And this is not the only
advantage of given family of crops. These crops are capable of improving land
fertility by accumulating organic matter. Besides, the absorption and accumulation
of nitrogen in the soil makes these crops unique in terms of their utility.
The nodule bacteria in the roots of those plants can absorb nitrogen from the air,
thus increasing considerably the nitrogen content both in the soil and in the plant.

V. Lessons Learned
Capacity building and human resources development for broader
implementation of IWRM in Central Asia (training, social mobilization,
etc.)
To address principal challenges, it is necessary to:
Establish a strong system of innovation implementation and dissemination of
experience on IWRM.
Promote innovations into water delivery services - to create stability and efficient
water supply, including: a) build up strong interrelations between water
hierarchy levels by economic, legal and managerial tools b) Water-Food–
Energy nexus.
Promote innovations into more effective water use, including: a) broad
implementation of water saving and reduce average water delivery per hectare
on 20-30% by 2030, b) increase water productivity on 50% by 2030, c)
cultivation of drought resistant crops.
Increase women involvement in water management and governance.
Pilot testing of IWRM in specific zones: a) in upper watershed, b) in lowlands of
Amudarya and Syrdarya rivers.

29
What are the new and emerging challenges related to water management
and food security?
It was established that in addition to the technological deficiencies and errors made by
the farmers, there are major issues related to improper or inadequate organization of
the water supply system by water suppliers, which have significant impact.
Existing regulations and laws on water planning and supply, set by the relevant
departments and ministries are mainly only up to WUA level.
There is no structure, which on a regular basis during their formation would give
recommendations on how new structures should work keeping in mind that organized
farms have a much smaller area than the old style of collective farms.
How they should use technological approaches in water allocation among farmers, what
legal operational documentation is necessary to take into account water demand and
supply, what should be the foundation that provides efficiency of the system of funding
the WUAs.
As a result, the first to suffer from a lack of organization, is the farmer and his fields, and
this affects the productivity of land and water.
