• 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

LEGUMESIt 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 LearnedCapacity 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.

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.
