Description; Chapters; Supplementary; This volume serves as a source of information on arid lands that is not otherwise available. Contents: Geomorphological Aspects of Sand Movement (K Badr El Din, H M Hassan, M Mainguet, P A Jacobberger, N S Embabi); Groundwater Exploration and Mapping (F El-Baz, R B Hoag & J C Ingari, R Majali); Field Studies (H E Dregne, H A Al-Sanad, E H . This country-level indicator measures the extension (in sq. Km) of livestock-only systems in rangeland-based arid and semi-arid areas [LGA]. The data comes frorm the Map of Global Livestock Production Systems (version 5), a joint initiative between FAO and ILRI. The full reference for the Map of Global Livestock Production Systems (version 5) is: Robinson TP, Thornton PK.
In arid environments the exploration and monitoring of water resources is a prerequisite for water accessibility and rational use and management. To survey large arid areas for water, conventional land-based techniques must be complemented by using Cited by: The project takes a three-step, innovative, common methodology – called Value Chain Analysis for Resilience in Drylands (VC-ARID) – to identify climate risk, adaptation options and opportunities for private sector development in Kenya, Senegal, Burkina Faso, Pakistan, Tajikistan and Ethiopia – specifically for the livestock and cotton.

Recent research in arid ecosystems indicates, however, that nutrients can be critical to production. We also think of desert precipitation as being unpredictable, in addition to low in quantity. Nevertheless, many of the major arid lands of the world are characterized by highly seasonal patterns of precipitation.

Arid and Semi Arid Lands (ASALs) are characterized by low and erratic rainfall, periodic droughts, irregular agricultural productivity and high water scarcity.
The hydrology of ASALs influences water security, environmental sustainability and agricultural production and availability of Author: Christopher Misati Ondieki.
This tool is especially applicable to the study of the deserts and arid lands of the Earth because of their immense size and their inaccessibility to detailed study by conventional means. In this book examples are given of the utility of aerial photographs and space images in the study of semi-arid, arid, and hyper-arid terrains.

The arid and semi-arid catchments in dry lands in general require a special effective management as the scarcity of resources and information which is needed to leverage studies and investigations. This book has been developed under UNESCO’s G-WADI programme and aims to provide state-of-the-art guidance for those involved in water science and management in arid and semi-arid areas concerning the modelling methods that are needed to characterise water resource systems and their sustainable yield, and to provide protection from pollution.
The ability to effectively maintain the functions of the ecosystem is closely related to the assessment of land resources within a conservation-utilization balance.
Land degradation is one of the most significant environmental treats on arid region ecosystems in terms of the use of these resources. In this chapter, the aim was to attract the attention to land degradation processes in Turkey Author: Selen Deviren Saygin.
This book provides an overview of arid and semi-arid lands conditions, their general characteristics, methods of management, conservation, exploitation, and reclamation. COVID Resources.

Arid and semi-arid regions occur in about 30% of the total land area of the world. An intensification of the desertification caused by global warming and poor land management practices endanger water resources. In arid lands the exploration and monitoring of water resources is a prerequisite for water accessibility, rational use and management.
Introduction. Land and water are the basic natural resources on which the existence of humankind depends. In all aspects of land use planning, it is necessary to study the potentials, problems, utilisation levels and suitability of land and water resources for various uses (Verburg et al.,Margules and Pressey, ).The United Nations (UN) has set a goal (Goal No.2; Sustainable Cited by: 3.

For the rugged Hajar Mountains of northern Oman, numer. Semi-arid ecosystems differ from true arid areas in structure and in the rate and regulation of ecosystem processes.
We differentiate between these two, and highlight cases of conversion from semi-arid to arid lands (desertification; Verstraete and Schwartz ). Despite protection measurements and their natural position, groundwater resources are very vulnerable due to natural and anthropogenic impacts.
This is especially emphasized in karst arid and semi-arid zones, due to increased requirements for water. Paper deals with the impacts of the sinkholes on groundwater quality on Abarkooh city in Iran.
There are 28 sinkholes located in Abarkooh plain. In this study, METRIC (Mapping ET at high Resolutions with Internal Calibration), an energy balance algorithm originally developed for application with Landsat imagery at a regional scale, was applied to very high resolution aircraft imagery (–2 m pixels) in the Texas High Plains.
Rapid Evaluation of Arid Lands (REAL): A Methodology: /ch Management of desert grasslands requires rapid, low technology, coarse assessment methods that provide a triage-like prioritization for the manager.
SuchCited by: 1. Rangelands are usually found in drylands or arid and semi-arid lands, where rainfall is low and variable resulting in the distribution of vegetation and other resources in an uneven and patchy manner. However not all rangelands are found in drylands (as indeed not all drylands are rangelands), and rangelands can include wetlands and forests too.

Deterioration in soil and plant cover have adversely affected nearly 50 percent of the land areas as the result of human mismanagement of cultivated and range lands.
North America and Spain have the largest percentage of their arid lands affected.Arid Lands Information Network (ALIN) is an International NGO that facilitates information and knowledge exchange to and between extension workers or infomediaries and arid lands communities in Kenya, Uganda and Tanzania.
The information exchange activities focus on small-scale sustainable agriculture, climate change adaptation, natural resources management and other livelihood issues.Mapping ET at High Resolution in an Advective Semi-Arid Environment with Airborne Multispectral Imagery World Environmental and Water Resources Congress Great Rivers April Performance of Penman-Monteith FAO56 in a Semiarid Highland Environment.
