Northern Great Basin: A Region of Continual Change

Journal Articles & Books
Diciembre, 2015

There are many controversies and conflicts surrounding land management in the Great Basin. The conflicts often revolve around the maintenance of native plant and animal communities. This paper outlines some of the historical aspects of plant community change and some of the unanticipated impacts of policies applied to the Great Basin during Euro-American exploration and settlement. This narrative provides readers with some background on the turbulent history of the Great Basin, and suggests the need for a coordinated vision for future Great Basin land management.

integrated modeling approach for estimating the water quality benefits of conservation practices at the River Basin Scale

Journal Articles & Books
Diciembre, 2014
México
Estados Unidos de América

The USDA initiated the Conservation Effects Assessment Project (CEAP) to quantify the environmental benefits of conservation practices at regional and national scales. For this assessment, a sampling and modeling approach is used. This paper provides a technical overview of the modeling approach used in CEAP cropland assessment to estimate the off-site water quality benefits of conservation practices using the Ohio River Basin (ORB) as an example.

Understanding transportation-caused rangeland damage in Mongolia

Mongolia

Mongolia, a vast and sparsely populated semi-arid country, has very little formal road infrastructure. Since the 1990s, private ownership and usage of vehicles has been increasing, which has created a web of dirt track corridors due to the communal land tenure and unobstructed terrain, with some of these corridors reaching over 4 km in width. This practice aids wind- and water-aided erosion and desertification, causing enormous negative environmental effects.

role of prescribed burn associations in the application of prescribed fires in rangeland ecosystems

Journal Articles & Books
Diciembre, 2014

Although the ecological thresholds for restoring fire-adapted ecosystems back to their original state are better understood than in the past, the key hurdle to reintroducing historical fire regimes at landscape scales is a social one. The objectives of this study were to assess the human dimensions of prescribed fire and evaluate the role of Prescribed Burn Associations (PBAs) in promoting the adoption of prescribed fire at the landscape scale. The study was conducted in 12 counties in Texas, consisting of clusters of four counties in each of three ecoregions.

Soil water repellency in rangelands of Extremadura (Spain) and its relationship with land management

Journal Articles & Books
Diciembre, 2013
España

Soil water repellency reduces infiltration capacity, enhancing overland flow and even runoff production, and may produce patchiness in water infiltration at the hillslope scale. Knowledge about hydrophobicity in rangelands of Mediterranean type climate and its relation with vegetation cover and land management is sparse. The objectives of the present work are to determine the degree and spatial occurrence of soil water repellency and to define its relationship with site characteristics, such as soil, vegetation and land management in rangelands of SW Spain.

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.
