Barriers to Sustainable Land Management in Central Asia
Humans depend on land resources for provisions, and the sustainability of land capital to provide sustenance becomes invaluable with population growth. Agriculture is one of the major economic sectors of the five ‘stans’, ...
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 ...
Environmental factors of spatial distribution of soil salinity on flat irrigated terrain
Inefficient irrigation and the excessive use ofwater on agricultural land in the Aral Sea Basin over several decades
have led to saline soils. The main objective of this paper is to identify the environmental predictors ...
Redrawing Soil Salinity Innovation-Focused Stakeholder Interaction for Sustainable Land Management in Khorezm Province, Uzbekistan
Addressing soil salinity in irrigated drylands is tightly linked with water and land management decisions thus requiring interdisciplinary engagement. The salinity mapping approaches in Central Asia are undertaken through ...
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 ...
Geostatistical monitoring of soil salinity in Uzbekistan by repeated EMI surveys
Soil salinization in the lower reaches of Amudarya is a constant threat. High seepage losses in irrigation water delivery
network and deteriorated drainage network result in rising groundwater tables. The shallowgroundwater
table ...
Modelling end‑of‑season soil salinity in irrigated agriculture through multi‑temporal optical remote sensing, environmental parameters, and in situ information
Accurate information of soil salinity levels enables for remediation actions in long-term operating irrigation systems with malfunctioning drainage and shallow groundwater (GW), as they are widespread throughout the Aral ...
Comparison and sensitivity of measurement techniques for spatial distribution of soil salinity
In Khorezm, a district of Uzbekistan situated in the Aral Sea Basin, soil
salinization is an important driver of soil degradation in irrigated agriculture. The main
objective of this study was to identify techniques that ...
The assessment of spatial distribution of soil salinity risk using neural network
Soil salinity in the Aral Sea Basin is one
of the major limiting factors of sustainable crop
production. Leaching of the salts before planting
season is usually a prerequisite for crop establishment
and predetermined water ...
