By Christopher Martius, Inna Rudenko, John P.A. Lamers, P.L.G. Vlek
This e-book summarizes a long term study venture addressing land and water use within the irrigated components of the Aral Sea basin. In an interdisciplinary method, typical and human sciences are mixed to explain the demanding situations of monetary transition that have an effect on using land, water and organic assets, ecological sustainability, fiscal potency and the livelihoods of the neighborhood inhabitants. The study specializes in Khorezm, a zone in Uzbekistan, positioned at the Amudarya river, within the middle of vital Asia. a chain of chapters describes the biophysical surroundings and the elements of society and associations that form land and water use. The booklet discusses thoughts and instruments to enhance land and water administration, and to reform the commercial process administration, in accordance with agronomic, hydrological, financial ans social reviews and modeling. The insights will not be in simple terms very important for Uzbekistan, yet for all nations in transitions and irrigated dryland parts in different places.

Agric For Meteorol 74(1–2):61–74 Chapter 3 Soils and Soil Ecology in Khorezm Akmal Akramkhanov, Ramazan Kuziev, Rolf Sommer, Christopher Martius, Oksana Forkutsa, and Luiz Massucati Abstract 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 Amudarya river delta was formed by ancient channels that carried large amounts of sediments.
Conservation agriculture holds the promise to sustain soil fertility and increase water-use efﬁciency. These practices consist of a judicious mix of reduced tillage operations, crop residue management and retention, and introducing suitable crop rotations. Comparing permanent beds and zero tillage with conventional tillage methods under irrigated conditions, Pulatov et al. (Chap. 13) show that appropriate crop residue management and crop rotation can increase soil organic matter, improve soil structure, and enhance moisture holding capacities.
