      Irrigation and Water Management Policy Highlights 3 Table of Contents More than a dozen countries have renewable water supplies at less than m3 per capita per year, a level at which water availability becomes a severe constraint on Increased efficiency in water use need not incur tradeoffs in equity or poverty reduction. • First manage rain – the ultimate source of water – then address water withdrawals from rivers and groundwater. • Agriculture in production landscapes – integrated ecosystem­agroecosystem linkages and multiple ­use concept. 2.

Groundwater Management Observations on KSA Strategies for Reform International Experience Introduction The findings in this presentation are a first attempt to survey the agricultural productivity and efficiency literature with regard to the explicit inclusion of water aspects in productivity and efficiency measurements.

      Efficiency also applies to policies involving the re-allocation of water between different users, e.g. within the agricultural sector, or from agriculture to municipal or environmental use. Re-allocation to higher-value uses produces net social benefits corresponding to the difference between the value of water in its old and new uses.

By financially assisting local agencies in implementing their water use efficiency projects and programs, this grant program helps to reduce the need for additional water supplies, reduce diversions, save energy, and improve water supply reliability. Below is a table summarizing the water savings benefits achieved from this grant program.

California is one of the most productive agricultural regions in the world, and is the major producer of many nuts, fruits, and vegetables. In fact, California is the only producer of 13 commodities and is a top producer of more than 74 different commodities in the U.S.

The state exports a huge quantity of agricultural products, bringing more than $20 billion into California’s economy.

with others to improve water resource management and the efficiency of water use throughout the western United States. In particular, this manual supports Reclamation's responsibility under the Reclamation Reform Act of (Sections a and b) and other Reclamation law, to encourage more efficient water use by the districts it serves.

A report from the Center for Irrigation Technology, Agricultural Water Use in California: A Update, refuted much of the Pacific Institute’s findings, estimating the potential of new water from agricultural water use efficiency to be far less at %, or approximatelyacre-feet per year.

Additionally, water use in agriculture is often highly inefficient with only a fraction of the water diverted for agriculture effectively used for plant growth, with the rest drained or lost viaFile Size: KB.

Agricultural water use efficiency can be improved by minimizing soil evaporation losses relative to plant transpiration in the field. The ability to quantify soil evaporation and plant transpiration provides information on irrigation amount for specific crop types and growth stages, which play key roles in the conservation and management of water.

If water transfers are to be used as one mechanism of responsive water management, the equity issues related to area-of-origin impacts will require continued attention. California enacted area-of-origin protection laws in the s partly in response to Los Angeles' controversial efforts to export water from the Owens Valley.

doi: / Farmers who build good soil health—by planting cover crops, for example—can improve their water efficiency as well; even small increases in organic matter can help the soil hold more water.

Agricultural water management is multidimensional in both the scale and types of access rights, as Table reveals. There are various rights for water, land, infrastructure and. We found that most management measures contribute to better water use efficiency by improving water availability to the crop while reducing unproductive water losses.

The main effect of crop, soil and irrigation management is an increase of the transpiration component in relation to runoff, soil evaporation and by: 9.

Using isotopic and nuclear techniques, constraints to water use efficiency were identified and appropriate land and irrigation management practices were put in place to enhance more crops per drop of water and improve soil water storage.

Adopting proven sustainable agricultural practices reduces water use per bushel. Research, innovation, and access to improved technologies, seeds, and improved irrigation techniques are essential to increasing the efficiency of water use. Agriculture needs to be part of. This will likely need to be achieved with less water, mainly because of growing pressures from urbanisation, industrialisation and climate change.

In this context, it will be important in future for farmers to receive the right signals to increase water use efficiency and improve agricultural water management, while preserving aquatic ecosystems.

Efficiency of agricultural water management in Spain has also been questioned due to large agricultural surpluses that are eventually subsidized by the Spanish government or the European Union’s Common Agricultural Policy (CAP).
