Development of a soil quality index for characterizing effects of land-use changes on degradation and ecological restoration of rangeland soils in a semi-arid ecosystem

Land Degradation and Development, 2020
The aim of this research was to study the influence of land‐use changes on degradation and ecological restoration of rangeland soils by quantifying 15 soil attributes and the subsequent development of a soil quality index (SQI).

Desert rangelands, degradation and nutrients

2000
It is well recognized that rangeland environments, especially degraded environments, are relatively infertile. Though arid lands are moisture limited, it is often stated that they are nutrient regulated. A discussion of rangeland soil nutrients relative to landscape degradation should include: (1) dynamics of nutrient distributions; (2) soil properties

A Conceptual Model of Arid Rangeland Degradation

BioScience, 1994
A major concern of managers of arid and semiarid rangelands is the progressive loss of secondary productivity and diversity over the past century (Breman and de Wit 1983, Dean and Macdonald in press, Downing 1978, Friedel et al. 1990, Le Houerou 1989, Schlesinger et al. 1990, Talbot 1961, West 1993).

Ecological Restoration and Control of Rangeland Degradation: Rangeland Management Interventions

2010
Synopsis The problems and prospects for reversing land degradation and for ecological restoration of degraded landscapes are reviewed. Animal husbandry on rangelands in NW China is under great pressure. This pressure is leading to a major transformation of the livestock sector, from one that is resource-driven (based on available forage, water, crop ...

Current vegetation structure and composition of woody species in community‐derived categories of land degradation in a semiarid rangeland in Kunene region, Namibia

Land Degradation and Development, 2020
Land degradation has put the world's rangelands under intense pressure and reduced their capacity to provide vital services to those who solely depend on them for survival.

Principles, problems, and priorities for restoring degraded rangelands.

The Rangeland Journal, 1990
Past and current research on restoring degraded rangelands was reviewed at a workshop held in July 1989 by the CSIRO Division of Wildlife and Ecology. Basic ecological and economic principles for restoration, and prevention of further degradation, were explored and priorities for future research were identified.

Processes in rangeland degradation, rehabilitation and recovery.

2009
Copyright © CAB International 2009 ; The mechanisms and processes of degradation and rehabilitation are analysed. The distinction is made between restoration and rehabilitation at the landscape level and the implications for whole rangeland ecosystems are considered.
