Participatory GIS Approach for Assessing Land Suitability for Rainwater Harvesting in an Arid Rangeland Environment

Journal Articles & Books
Diciembre, 2012
Jordania
África septentrional

The dry rangelands of West Asia and North Africa are fragile and severely degraded due to low rainfall and mismanagement of natural resources. Rainwater harvesting (RWH) interventions are used to increase soil moisture content, vegetation cover, and productivity. However, adoption of rainwater harvesting by communities is slow. To understand adoption constraints and to develop options for sustainable integration of rainwater harvesting, a benchmark watershed was established in the dry rangelands of Jordan.

Assessing Degradation of Abandoned Farmlands for Conservation of the Monte Desert Biome in Argentina

Journal Articles & Books
Diciembre, 2014
Argentina

Land abandonment is a major issue worldwide. In Argentina, the Monte Desert is the most arid rangeland, where the traditional conservation practices are based on successional management of areas excluded to disturbances or abandoned. Some areas subjected to this kind of management may be too degraded, and thus require active restoration. Therefore, the aim of this study was to assess whether passive succession-based management is a suitable approach by evaluating the status of land degradation in a protected area after 17–41� years of farming abandonment.

Assessing Transportation Infrastructure Impacts on Rangelands: Test of a Standard Rangeland Assessment Protocol

Journal Articles & Books
Diciembre, 2010

Linear disturbances associated with on- and off-road vehicle use on rangelands has increased dramatically throughout the world in recent decades. This increase is due to a variety of factors including increased availability of all-terrain vehicles, infrastructure development (oil, gas, renewable energy, and ex-urban), and recreational activities.

Revolutionary Land Use Change in the 21st Century: Is (Rangeland) Science Relevant?

Journal Articles & Books
Diciembre, 2012

Rapidly increasing demand for food, fiber, and fuel together with new technologies and the mobility of global capital are driving revolutionary changes in land use throughout the world. Efforts to increase land productivity include conversion of millions of hectares of rangelands to crop production, including many marginal lands with low resistance and resilience to degradation. Sustaining the productivity of these lands requires careful land use planning and innovative management systems.

How Can Science Be General, Yet Specific? The Conundrum of Rangeland Science in the 21st Century

Journal Articles & Books
Diciembre, 2012

A critical challenge for range scientists is to provide input to management decisions for land units where little or no data exist. The disciplines of range science, basic ecology, and global ecology use different perspectives and approaches with different levels of detail to extrapolate information and understanding from well-studied locations to other land units.

Invasive weeds in rangelands: Species, impacts, and management

Journal Articles & Books
Diciembre, 2000
Estados Unidos de América

Rangeland and pastures comprise about 42% of the total land area of the United States. About three-quarters of all domestic livestock depend upon grazing lands for survival. Many ranges have had domestic stock grazing for more than 100 years and, as a result, the plant composition has changed greatly from the original ecosystems. Western rangelands previously dominated by perennial bunchgrasses have been converted, primarily through overgrazing, to annual grasslands that are susceptible to invasion by introduced dicots. Today there are more than 300 rangeland weeds in the United States.

Grazing management or physiography? Factors controlling vegetation recovery in Mediterranean grasslands

Journal Articles & Books
Diciembre, 2013
España

Grazing intensification and abandonment are increasing the risk of degradation of Mediterranean grasslands. The development of techniques for monitoring grazing effects on herbaceous vegetation is an essential need for the management of these rangelands. However, the high variability of these systems make physiographical and management effects hard to disentangle and quantify. We present a methodology to support rangeland management and assess grazing effects on environmentally heterogeneous areas, and provide an example of its application in a Mediterranean rangeland in central Spain.

Effects of Slash on Herbaceous Communities in Pinyon-Juniper Woodlands of Northern Arizona

Journal Articles & Books
Diciembre, 2008

Scattering slash (downed woody materials) after tree removal is increasingly prescribed by land managers as a treatment to promote the establishment and growth of understory vegetation in pinyon-juniper woodlands. However, the effects of scattering slash on soil resources and plant communities are poorly understood and often confounded with the release from tree competition.

Modeling relationships between catchment attributes and river water quality in southern catchments of the Caspian Sea

Journal Articles & Books
Diciembre, 2015

Increasing land utilization through diverse forms of human activities, such as agriculture, forestry, urban growth, and industrial development, has led to negative impacts on the water quality of rivers. To find out how catchment attributes, such as land use, hydrologic soil groups, and lithology, can affect water quality variables (Ca²⁺, Mg²⁺, Na⁺, Cl⁻, HCO₃⁻, pH, TDS, EC, SAR), a spatio-statistical approach was applied to 23 catchments in southern basins of the Caspian Sea.

Legal barriers to effective ecosystem management: exploring linkages between liability, regulations, and prescribed fire

Journal Articles & Books
Diciembre, 2015
Estados Unidos de América

Resistance to the use of prescribed fire is strong among many private land managers despite the advantages it offers for maintaining fire‐adapted ecosystems. Even managers who are aware of the benefits of using prescribed fire as a management tool avoid using it, citing potential liability as a major reason for their aversion. Recognizing the importance of prescribed fire for ecosystem management and the constraints current statutory schemes impose on its use, several states in the United States have undertaken prescribed burn statutory reform.

Can ecological land classification increase the utility of vegetation monitoring data?

Journal Articles & Books
Diciembre, 2016
Estados Unidos de América

Vegetation dynamics in rangelands and other ecosystems are known to be mediated by topoedaphic properties. Vegetation monitoring programs, however, often do not consider the impact of soils and other sources of landscape heterogeneity on the temporal patterns observed. Ecological sites (ES) comprise a land classification system based on soil, topographic, and climate variations that can be readily applied by land managers to classify topoedaphic properties at monitoring locations.
