(source: Nielsen Book Data) Summary Salinization of land and water is an increasing problem in many areas of the world, particularly in arid and semi-arid regions where irrigation is a contributory factor. This book assesses the extent, human causes and management of salinization. Irrigation Slide 3 Un-sustainability of Irrigation • Globally, 71% of withdrawn freshwater is used for irrigation • Rivers dammed to collect irrigation water – People living in areas behind the dams are displaced – Wildlife habitat destroyed • Irrigation depletes rivers and aquifers • Irrigation degrades water, soil, and wildlife habitatFile Size: KB.
In the United States the patterns of precipitation, water use, and water management problems are highly variable. In examining these patterns it is common to divide the country into relatively dry and wet regions at the th meridian. This book opens a new pathway for global mapping that is focused on a specific land use theme, such as irrigated or rain-fed croplands and classes within these themes. Since croplands use most of the water consumed by humans, specific knowledge of irrigated and rain-fed croplands will be critical for precise estimates of water use.

Notably, the salinization of irrigated lands in Mesopotamia and filling up of ditches with sediments— cleaned out by enslaved Israelites among others—resulted in lost land fertility and an inability to sustain large centrally governed civilizations.
Today, many of the most productive agricultural areas depend on some type of water. Chapter 4F: Irrigation Water Management Soil-Water-Plant Relationships Effective and efficient irrigation begins with a basic understanding of the relation-ships among soil, water, and plants.
Figure 4f-2 illustrates the on-farm hydrologic cycle for irrigated lands, and Table 4f-1 provides definitions of several terms associated with irrigation. Land and water management planning for increasing farm income in irrigated dry areas The global population is continuously increasing and good quality land and water resources are simultaneously declining.
and regional level decisions of optimal resources allocation and are able to solve the waterlogging problems of irrigated. DRAINAGE OF IRRIGATED LANDS is the ninth in a series of training manuals on irrigation. It discusses the need for drainage in irrigated areas, focussing on drainage at the farm level.
Irrigation and Water Management Policy Highlights 3 1 1 INTRODUCTION Over billion people worldwide depend on irrigation for food, employment and income. Since the early s, over a million ha of new irrigated land have been created.
By the late s, irrigated agriculture in. Subirrigation water management requirements depend on the soil characteristics within the irrigated field and surrounding areas. Sufficient water must be provided to raise the water table level as high as 18 to 24 inches below the soil surface.
Water is required to fill the pores of the soil and also satisfies evaporation and subsurface runoffFile Size: KB. Irrigation is the application of controlled amounts of water to plants at needed intervals.
Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall.
Irrigation also has other uses in crop production, including frost protection, suppressing weed growth in grain fields and preventing soil. Get this from a library.

This book summarizes results from a long-term research project addressing land and water use in irrigated areas of the Aral Sea basin. In an interdisciplinary approach, natural and human sciences are combined to elucidate challenges of economic transition that affect the use of land, water and biological resources, ecological sustainability, economic efficiency and the livelihoods of the local.
Salinisation of land and water is an increasing problem in many areas of the world, particularly in arid and semi-arid regions where irrigation is a contributory factor.
This book assesses the extent, human causes and management of salinisation. The first part of the book provides an extended review of general issues, including a history of secondary salinisation, followed by a discussion of.
Wet land preparation can consume up to a third of the total water required for growing rice in an irrigated production system.
If water cost or availability at the time of crop establishment is a concern, consider dry land preparation which uses considerably less water than wet land preparation.

Pasture Management Written by Rich Casale, District Conservationist and CPESC#3 are irrigated. For example, less water is needed and pasture management objectives. Past land use practices have caused serious damage to soil and plant resources in some areas requiring a great deal more time, expense and effort in maintaining pasture File Size: KB.
Irrigation Water Management Water management is an important element of irrigated crop production. Efficient irrigation systems and water management practices can help maintain farm profitability in an era of limited, higher-cost water supplies. Efficient water management may also reduce the impact of irrigated production on offsite water.

Irrigation management. Irrigation management is crucial to product quality in vegetable crops. Transition in the USA from dryland to irrigated agriculture, or from flood and low-efficiency sprinkler irrigation, to center pivot and drip irrigation systems has occurred rapidly over the last few decades.

E.A. Holzapfel, M.A. Mariño, in Encyclopedia of Ecology, Water resource management is of paramount importance in agricultural development. Sustained socioeconomic development in countries with irrigated agriculture could be limited by water availability and deterioration in water quality. Focusing on the developing contries of Asia, Africa and South America, chapters explore the diverse livelihoods of people in these areas, the impact of land-water management on environments, new techniques and methodologies and lessons learned in land and water management to solve the conflicts between agriculture, aquaculture and fisheries.
