Agricultural extension in Central Asia: existing strategies and future needs
Agriculture is at the forefront of the development objectives of the republics of Central Asia (CA). Since independence in 1991, these countries have undergone transitions from being centrally planned economies to market-oriented systems, which did not include the creation of agricultural extension systems. This paper provides information on the current status of the agricultural extension systems in CA with special reference to Kyrgyzstan, Tajikistan and Uzbekistan. We reviewed the existing extension strategies, donor- and state-driven initiatives to revitalize the agricultural extension systems, informal linkages that nongovernmental organizations play in helping a limited number of farmer...
. Root zone salinity management using fractional skimming wells with pressurized Irrigation: proceedings of the Project-End Workshop 2003
Detailed hydro-geological investigations were carried out while implementing SCARPs in the Chaj Doab. These investigations yielded a data set of groundwater quality at different depths of the aquifers (spatial) especially in the SCARP-II saline zone. In MREP area, 138 public tubewells, having strainers from 30-35 m till 60-75 m depth of the aquifer, were installed during the 1970s to help meet the irrigation water demand at farm level. The MREP, who was made responsible for operation and maintenance of these deep tubewells, continuously monitored the performance of these tubewells as well. Therefore, the pumped groundwater quality data (temporal) of these spatially distributed tubewells was ...
Life in the Himalaya
The collision of the Indian and Eurasian plates 50 million years ago created the Himalaya, along with massive glaciers, intensified monsoon, turbulent rivers, and an efflorescence of ecosystems. Today, the Himalaya is at risk of catastrophic loss of life. Maharaj Pandit outlines the mountain’s past in order to map a way toward a sustainable future.

Water resources management in Afghanistan: The issues and options
This report presents the analysis of current status of water resources management in Afghanistan and identify steps for maximizing the use ofavailable water resources to enhance crop productivity and environmental sustainability.
Sustainable Agriculture Reviews 52
This book presents advanced knowledge and techniques to improve food quality, such as organic farming, fertilization using waste, reducing arsenic in food, soil restoration, forage production in arid regions and weed control. Agriculture is actually facing two major challenges, feeding an ever-growing population and providing safe food in the context of pollution, climate change and the future circular economy.

Strategies for the Management of Conjunctive Use of Surface Water and Groundwater Resources in Semi-arid Areas
Due to inadequate rainfall, groundwater has acquired a vital role in the development of Pakistan's agricultural economy. However, a lack of awareness concerning the use of groundwater, either by itself or combined with canal water, has added large amounts of salt to the soil. As a result, large tracts of irrigated lands are already salinized, while many others are under threat. This report presents the results of a modeling study carried out to evaluate the long-term effects of a different quality of irrigation water on root zone salinity. The simulations were performed for the Rechna Doab (sub basin of the Indus Basin) in Pakistan, by using 15 years of actual rainfall and climatic data.
