Conservation Agriculture in Central Asia
This chapter aims to provide an up-to-date state-of-the-art review on various aspects of Conservation Agriculture (CA) by reviewing the past and current research from various countries in CA.
Conversion Factors to Estimate Soil Salinity Based on Electrical Conductivity for Soils in Khorezm Region, Uzbekistan
This paper compares different procedures for soil salinity analyses to determine
electrical conductivity: saturated paste extract (ECe), xed soil:water
ratio extracts EC1:1 and EC1:5, and soil solution paste prepared with ...
Chapter 21: Economics of Land Degradation and Improvement in Uzbekistan
Land degradation is a major challenge for agricultural and rural development
in Uzbekistan. Our research findings indicate that the costs of land
degradation in Uzbekistan are substantial; reaching about 0.85 billion USD ...
Soils and Soil Ecology in Khorezm
The current status of the agricultural soils in Khorezm is closely linked to their development influenced by past river flows and more recent human-managed irrigation and drainage practices. The initial relief of the ...
Managing Soil Salinity in the Lower Reaches of the Amudarya Delta: How to Break the Vicious Circle
This case study focuses on the vicious circle of soil
salinization: agriculture’s consumption of large
amounts of water contributes to shallow groundwater,
leading to recurring soil salinity, which in
turn demands more ...
Mapping Cropland Abandonment in the Aral Sea Basin with MODIS Time Series
Cropland abandonment is globally widespread and has strong repercussions for regional
food security and the environment. Statistics suggest that one of the hotspots of abandoned cropland
is located in the drylands of the ...
Biomass Productivity-Based Mapping of Global Land Degradation Hotspots
Land degradation affects negatively the livelihoods and food security of
global population. There have been recurring efforts by the international community
to identify the global extent and severity of land degradation. ...
A new concept of irrigation response units for effective management of surface and groundwater resources - A case study from the multi-country Fergana valley, Central Asia.
When estimating canal water supplies for largescale irrigation schemes and especially in arid regions worldwide, the impact of all factors affecting the gross irrigation requirements (GIR) are not properly accounted for, ...
Conservation agriculture in Central Asia—What do we know and where do we go from here?
Rainfed and irrigated agricultural systems have supported livelihoods in the five Central Asian countries
(CAC) for millennia, but concerns for sustainability and efficient use of land and water resources are longstanding.
During ...
Conservation Agriculture for combating land degradation in Central Asia: a synthesis
This manuscript reviews scientific findings on agricultural systems, associated land
degradation and selected remedies such as Conservation Agricultural (CA) practices to
counterbalance these. In particular, this review ...
