Salinisation of land and water resources
Human-induced salinisation is a major threat to the world"s land and water resources. Inadequate development of irrigation projects, inefficient irrigation, lack of proper drainage, and environmental mismanagement such as the clearing of native vegetation, are responsible for the loss of millions of hectares of agricultural and grazing land, as well as the misuse of scarce water resources. The first part of this book analyses the problem in the context of the world"s population, its climate and its land and water resources. It reviews irrigation methods and crop water requirements, the processes of salinisation, and its management. The second part describes irrigated land, dryland and water-resource salinity problems in 11 countries, which contain approximately 70 per cent of the world"s irrigated land. In each case study, background data, environmental conditions and past management practices are given to provide an understanding of why salinity occurs in particular places, and of the management methods employed against it.

Since , Land and Water Resources, Inc., in Rosemont, Illinois, has been a national leader in creating, building, and managing wetland mitigation banks. As one of the nation's first private mitigation bankers, LAWR received its first permit from the Corps and Illinois Department of Natural Resources in for the nationally-acclaimed Otter. Salinity is the accumulation of salt in land and water to a level that damages the natural and built environment. Many parts of the Australian landscape are naturally salty but human activities can cause salt levels to rise. Salinity and water are inextricably linked. This means salinity is affected by climate variability, which can tend.

Decreased biodiversity, changes in the natural character of aquatic ecosystems, and lower productivity are frequent ecological effects. In some dryland countries, salinisation is viewed as the single most important threat to water resources. However, the extent and importance of salinisation as a global threat has been greatly by: Soil salinisation is a widespread soil degradation process, exacerbated by a mismatch between water demands for irrigation in food production and the amount of quality (non-saline) water.
Different land, crop and/or water management approaches (e.g. conservation tillage, crop selection/rotation, groundwater level control) have been used to Cited by: Home; All editions; Salinisation of land and water resources: human causes, extent, management, and case studies / F. Ghassemi, A.J.
Jakeman, H.A. Nix Ghassemi, F. excellent account of salinization around theworld is given in the book “Salinisation of Land and Water Resources” by F. Ghassemi, A.J. Jakeman and H.A. Nix (). Climatic groupings are a useful indicator of the nature andpotential for salinization (Ghassemi et al., ), butfunctionally it is useful to consider dryland orirrigated salinity.
Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization.
Salts occur naturally within soils and water. Salination can be caused by natural processes such as mineral weathering or by the gradual withdrawal of an ocean.
It can also come about through artificial processes such as irrigation and road salt. The State of Land and Water Resources (SOLAW) is FAO's first flagship publication onthe global status of land and water resources. It is an 'advocacy' report, to be published every 3 to 5 years, and targeted at senior level decision makers in agriculture as well as in other sectors.

Soil salinity control relates to controlling the problem of soil salinity and reclaiming salinized agricultural land.
The aim of soil salinity control is to prevent soil degradation by salination and reclaim already salty (saline) soils. Soil reclamation is also called soil improvement, rehabilitation, remediation, recuperation, or. Water, an international, peer-reviewed Open Access journal.
Dear Colleagues, The aim of this Special Issue of Water is to present the latest research on the quantification of surface and groundwater salinization processes in the surface water–soil–aquifer continuum. The most susceptible zones to such processes are coastal areas, which are also the most populated regions of the Earth.
Many countries in the world have made great efforts, to remedy the water shortage, by providing financial and technical backing, for water desalination, treatment of wastewater and improved management and conservation techniques. Water ministries, universities and research centres have supported scientific research, and applied the most recent technologies, in search of new and alternative.
The salinisation of rivers is a global problem that affects to countries all over the world and it causes a high environmental and economic cost, and poses a high risk to global health. Climate. The four land categories ranged from extremely degraded land through to normal land and were based on the severity of waterlogging (depth of water table) and the soil salinity.
The Net Present Values (NPV) of the three strategies on the four land categories were compared over a period of 25 years, using a discount rate of 6 %.Cited by: Ghassemi F, Jakeman AJ, Nix HA () Salinisation of land and water resources: human causes, extent, management and case studies.

the water defficits make the survival of natural vegetation and crops difficult or impossi-ble. These moisture deficits are due to the difficulties for the plants to use the water sto-red in the soil ("saline soils"), or to the difficulties for root development and for water infiltration into the soil ("sodic soils").File Size: 1MB.

Why do some people oppose dams. Answer: Some people oppose dams because this may submerge the land for cultivation and disrupt the lives of the displaced people. Short Answer Type. Salinisation has important impacts on the goods and services that rivers provide to humans and therefore it may have high economic costs.
For example, the salinisation of the Ganges water in Bangladesh has resulted in losses of millions of dollars related to crop and industrial machinery damage and posed a risk to human health (Mirza, ).Cited by:. ADVERTISEMENTS: After reading this article you will learn about the classification of resources.
The resources that are essentially inexhaustible in considered as renewable resources. Solar, wind, tides and flowing water falls under this categories. It is expected that the solar energy will last at least billion years while the sun completes its lifecycle. ADVERTISEMENTS: [ ].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 .bores are due to flushing of the saline soil water to the groundwater due to land clearing, and in some cases by irrigation.
The time scale of salinisation depends on the underlying salt inventory, the soil type and the intended land-use; from tens of years for sandy soils with high salinities to hundred of years for clay soils.
