Approximately half of the irrigated area of Iran falls under different types of salt-affected soils and average yield losses may be as high as 50 percent. Slightly and moderately salt-affected soils are mostly found on the piedmonts at the foot of the Elburz (Alborz) Mountains in the northern part of the country. The soils having severe to extreme salinity are predominantly located in the Central Plateau, the Khuzestan and Southern Coastal Plains and the Caspian Coastal Plain. The process of salinization of the surface water resources is mainly due to natural conditions, and to a lesser extent, to the discharge of drainage water into the river systems. Estimates show that about 6.7 km3 of brackish water flow annually through 12 major rivers. There is no straightforward solution to the complex problems of salt-induced soil and water resources degradation in Iran. The approaches addressing the management of these resources need to be multidimensional and must take into account biophysical and environmental conditions of the target areas as well as livelihood aspects of the associated communities.

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.

This handbook has been prepared for the training workshop on innovative methods of amelioration and use of salt-affected soils, which takes place in Kharkiv, Ukraine, in September 2017. This workshop is conducted within the framework of the Implementation Plan of the Eurasian Soil Partnership, which is a sub-regional affiliation of the Global Soil Partnership. The main goals of the Global Soil Partnership (GSP) and Regional Soil Partnerships (RSPs) include the development of global and regional plans of action for the sustainable management and monitoring of limited soil resources as a key element, as well as the maintenance of food security and ecological services of soils. The RSPs rely on the existing regional networks that connect the national and local networks, partners, projects and measures to ensure that the interests of all member countries of the partnership are taken into account. A RSP should give directives for the development of regional targets, priorities and ìrequred mechanisms of implementation and also undertake regular assessments of progress in reaching goals and accomplishing the tasks. The Eurasian Region covers Eastern Europe, Central Asia and Caucasus and includes the following countries: Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia, Tajikistan, Turkey, Turkmenistan, Ukraine and Uzbekistan. The Eurasian Region is diverse in terms of climatic conditions, soils, flora and fauna, land use and human activities. Soil degradation is a serious problem within this region, with its most destructive consequences including salinization, erosion, loss of soil organic matter, nutrients and biodiversity as well as soil compaction. Soil salinization presents a serious challenge that requires co-ordination between countries that share common water and land resources. International co-operation is also needed to attract and manage investment into water and land resources. It should be emphasized that salinization is both the cause and the result of other agricultural problems. Combating salinization should, together with other measures for achieving the sustainable intensification of agriculture, be considered as a basis for food security..

Irrigation has long played a key role in feeding expanding populations and is expected to play a still greater role in the future. However, is it sustainable? Can it remain in existence and function continuously and indefinitely? Some pessimists doubt that it is. This volume presents a more positive approach with carefully conditional optimism. It takes the diffuse, voluminous and disparate facts and combines them in a unified exposition. It merges physico-chemical, agronomic, environmental and economic principles into practical recommendations to help ensure the long-term viability and productivity of irrigated agriculture in arid and semiarid regions.

Salinity affects 10 to 16% of all irrigated lands while the annual rate of land loss due to waterlogging and salinity is about 0.5 million hectares per year. In this dissertation, the role of subsurface drainage to reduce these problems in irrigated agriculture in arid and semi-arid regions has been analysed and challenges for improving subsurface drainage practices have been formulated. Although the installed subsurface drainage systems are in general technically sound and cost-effective, drainage development lags behind irrigation development and consequently a substantial part of the irrigated areas suffers from waterlogging and salinity. This is mainly because the subsurface drainage systems are designed and implemented by government, with the users, the small farmers, having little responsibility and having little input. In the adopted top-down approach the location-specific conditions and farmers’ preferences are hardly taken into consideration. Furthermore, the emphasis has been on the technical aspects (the physical infrastructure), while the organizational aspects (institutional infrastructure) have been largely neglected. To reverse the negative trend in salt build-up and waterlogging in irrigated lands in semi-arid and arid regions, a number of challenges for enhancing the role of subsurface drainage have been formulated: (i) balancing top-down against bottom-up, (ii) from standardization to flexibility and (iii) focus on capacity development.
