Is Proactive Adaptation to Climate Change Necessary in Grazed Rangelands?

Journal Articles & Books
Diciembre, 2012

In this article we test the notion that adaptation to climate change in grazed rangelands requires little more effort than current approaches to risk management because the inherent climate variability that characterizes rangelands provides a management environment that is preadapted to climate change. We also examine the alternative hypothesis that rangeland ecosystems and the people they support are highly vulnerable to climate change.

Characterization of enclosure management regimes and factors influencing their choice among agropastoralists in North-Western Kenya

Journal Articles & Books

África

The enclosure system is an increasingly popular approach for land rehabilitation among communities inhabiting the arid and semi-arid lands in Africa. However, the mixed results associated with its adoption by households call for an in-depth understanding of the management regimes.

Quantification of aboveground rangeland productivity and anthropogenic degradation on the Arabian Peninsula using Landsat imagery and field inventory data

Journal Articles & Books
Diciembre, 2011
Omán

The productivity of semi-arid rangelands on the Arabian Peninsula is spatially and temporally highly variable, and increasing grazing pressure as well as the likely effects of climatic change further threatens vegetation resources. Using the Al Jabal al Akhdar mountains in northern Oman as an example, our objectives were to analyse the availability and spatial distribution of aboveground net primary production (ANPP) and the extent and causes of vegetation changes during the last decades with a remote sensing approach.

Linking degradation assessment to sustainable land management: A decision support system for Kalahari pastoralists

Journal Articles & Books
Diciembre, 2010
Botswana

This paper describes a manual-style Decision Support System that integrates land degradation indicators with adaptive management options and is designed for land managers to easily collect data and monitor progress towards environmental sustainability goals. A number of similar tools have been developed for ranchers in southern Africa, but there has been little help for land managers under common property regimes. Manuals were therefore primarily designed for use by communal pastoralists in three study areas in the Kalahari, Botswana.

State-and-Transition Models for Heterogeneous Landscapes: A Strategy for Development and Application

Journal Articles & Books
Diciembre, 2009

Interpretation of assessment and monitoring data requires information about how reference conditions and ecological resilience vary in space and time. Reference conditions used as benchmarks are often specified via potential-based land classifications (e.g., ecological sites) that describe the plant communities potentially observed in an area based on soil and climate. State-and-transition models (STMs) coupled to ecological sites specify indicators of ecological resilience and thresholds.

Land-use/cover dynamics in Northern Afar rangelands, Ethiopia

Journal Articles & Books
Diciembre, 2010
Etiopía

This study uses a combination of remote sensing data, field observations and information from local people to analyze the patterns and dynamics of land-use/cover changes for 35 years from 1972 to 2007 in the arid and semi-arid Northern Afar rangelands, Ethiopia. A pixel-based supervised image classification was used to map land-use/cover classes. People's perceptions and ecological time-lines were used to explain the driving forces linked to the changes. A rapid reduction in woodland cover (97%) and grassland cover (88%) took place between 1972 and 2007.

Monitoring of Livestock Grazing Effects on Bureau of Land Management Land

Journal Articles & Books
Diciembre, 2014
Estados Unidos de América

Public land management agencies, such as the Bureau of Land Management (BLM), are charged with managing rangelands throughout the western United States for multiple uses, such as livestock grazing and conservation of sensitive species and their habitats. Monitoring of condition and trends of these rangelands, particularly with respect to effects of livestock grazing, provides critical information for effective management of these multiuse landscapes.

Rangeland development of the Mu Us Sandy Land in semiarid China: an analysis using Landsat and NOAA remote sensing data

Journal Articles & Books
Diciembre, 2003
China

Degradation of the dry semiarid ecosystems in the Mu Us Sandy Land of north central China was explored using high-resolution satellite images from 1978, 1987 and 1996. This study monitored both changes in grassland biomass production and reclamation activities to detect the nature and scale of land degradation since major economic reforms were introduced in 1978. The position of the high-resolution images within the vegetation cycles was inspected from National Oceanographic and Atmospheric Administration (NOAA) NDVI images at 10-day repetition and seasonal precipitation patterns.

good shepherd: remedying the fencing syndrome

Journal Articles & Books
Diciembre, 2013
Sudáfrica
África austral

In this paper the use of fenced grazing camps to manage the rangeland commons is challenged. A historical perspective is presented on fencing and rotational grazing in South Africa. Two case studies in KwaZulu-Natal and the Northern Cape illustrate the factors that influence the management of rangelands under communal land tenure without the use of fences. It is argued that herding is preferred over fencing.

Reshaping women's land rights on communal rangeland

Journal Articles & Books
Diciembre, 2013

This paper aims to contribute to the debates on communal rangelands and analyses the gendered dimension of land rights and land access in the rural areas of Namaqualand. The actual gender relations within rural communities and the emergence of strategies that are being pursued in communal land processes are obscured and often ignored in policies about communal rangelands, which overemphasise ‘the ecological and economic impact’ and the balancing of these dimensions.
