South Africa - South Africa - Soils: South Africa contains three major soil regions. East of approximately longitude 25° E, soils have formed under wet summer and dry winter conditions; the more-important soil types there are laterite (red, leached, iron-bearing soil), unleached subtropical soils, and gleylike (i.e., bluish gray, sticky, and compact) podzolic soils (highly leached soils that. Soil and water conservation is - in its outlines- a worldwide strategy in the context of a sustainable and poverty-orientated natural resource management (Rauch ).. Soil and water conservation are those activities at the local level which maintain or enhance the productive capacity of the land including soil, water and vegetation in areas prone to degradation through.
The aim of this study was to analyse agricultural drought, and to evaluate soil and water management options and strategies for sustainable crop production in drought-prone semi-arid Kenya. Research was conducted at an experimental site in Katumani and in Iiuni watershed, both in Machakos by: Four opportunities for low-input management of soil fertility in semi-arid eastern Uganda have been verified as economical using farmer participatory approaches; information dissemination is underway and more detailed research has .

Project research report, Various soil water management practices have been developed and promoted for the semi arid areas of Zimbabwe. The wells are again, primarily, used for domestic purposes, but in several cases also for small-scale irrigation.
Conclusion and discussion Water harvesting systems for crop production has a large potential in semi-arid regions of Eastern and Southern Africa; a Cited by: In arid and semi-arid regions of the world, where precipitation is exceeded by potential evapotranspiration, soils are incompletely leached and CaCO 3 accumulates in significant quantities.
Figure 18 illustrates the global distribution of carbonate in the upper meter of soils. As the figure illustrates, there is a sharp boundary between calcareous and noncalcareous soil in the USA at about. To assess the impact of soil management in a meaningful way and in terms that can be applied in a variety of situations is nearly impossible with existing information.
Baeumer and Bakermans () at the conclusion of their review on zero-tillage indicate their frustration as follows: “Yet, as shown by our review, only little has been gained Cited by: The semi-arid tropics (SAT) encompass parts of 48 developing countries including most of India, parts of southeast Asia, a swathe across sub-Saharan Africa, much of southern and eastern Africa, and parts of Latin America.
Many of these countries are among the poorest in the world. Definitions • Drylands cover approximately 40% of the world’s land area, and support two billion people, 90% of whom live in developing countries. These areas receive relatively low overall amounts of precipitation in the form of rainfall or snow (UN, ; MEA ).

The performance and cost-efficiency of off-season small-scale irrigation in arid and semi-arid areas of sub-Saharan Africa can be optimised by means of off-season rainwater harvesting irrigation management (RWHI), which is a subset of rainwater harvesting technologies and practices that allows concentrating and storing rainwater to be used for off-season small-scale Author: Josep de Trincheria Gomez, Desalegn Dawit, Sebastiao Famba, Walter Leal Filho, Maimbo Malesu, Paula.

Irrigated area is about million ha which represents 9% percent of the million ha of cultivated area (FAO, ).scientific interest is very recent. In sub-Saharan Africa particularly, it can be argued that RWH occupies the knowledge gap between the two extremes that have previously received far greater attention.
