Appraising and selecting conservation measures to mitigate desertification and land degradation based on stakeholder participation and global best practices

Journal Articles & Books
Dezembro, 2009

Most desertification research focuses on degradation assessments without putting sufficient emphasis on prevention and mitigation strategies, although the concept of sustainable land management (SLM) is increasingly being acknowledged. A variety of already applied conservation measures exist at the local level, but they are not adequately recognised, evaluated and shared, either by land users, technicians, researchers, or policy makers. Likewise, collaboration between research and implementation is often insufficient.

Farmers' perception of environmental degradation and their adoption of improved management practices in Alxa, China

Journal Articles & Books
Dezembro, 2009
China

The environment and the natural resource base have been severely degraded in Alxa League, western Inner Mongolia, China, over the past half-century. This study reports surveys that reveal farmers' perceptions of environmental degradation and their adoption of improved management practices in this poor and remote desert region. Surveys were made in villages that had been engaged in a large environmental rehabilitation and management project [Alxa League environmental rehabilitation and management project (ALERMP)] and those that had not.

Effect of conservation management on bees and insect-pollinated grassland plant communities in three European countries

Hungria
Suíça
Países Baixos

It is now widely accepted that agricultural intensification drives the decline of biodiversity and related ecosystem services like pollination. Conservation management, such as agri-environment schemes (AES), has been introduced to counteract these declines, but in Western European countries these tend to produce mixed biodiversity benefits. Not much is known about the effects of AES in Central and Eastern European countries. We evaluated the effect of reduced stocking rates (0.5cow/ha vs. >1cow/ha) on bees and insect-pollinated plants in semi-natural pastures in Hungary.

Limitations to Postfire Seedling Establishment: The Role of Seeding Technology, Water Availability, and Invasive Plant Abundance

Journal Articles & Books
Dezembro, 2010

Seeding rangeland following wildfire is a central tool managers use to stabilize soils and inhibit the spread of invasive plants. Rates of successful seeding on arid rangeland, however, are low. The objective of this study was to determine the degree to which water availability, invasive plant abundance, and seeding technology influence postfire seedling establishment. Across four fire complexes, whole plots were either seeded using a rangeland drill, seeded by hand where seeds could be placed at an exact depth, or left as unseeded controls.

Vegetation Characteristics of Mountain and Wyoming Big Sagebrush Plant Communities in the Northern Great Basin

Estados Unidos

Dominant plant species are often used as indicators of site potential in forest and rangelands. However, subspecies of dominant vegetation often indicate different site characteristics and, therefore, may be more useful indicators of plant community potential and provide more precise information for management. Big sagebrush (Artemisia tridentata Nutt.) occurs across large expanses of the western United States.

The role of land survey in land expropriation for state or public needs [Latvia]

Policy Papers & Briefs
Dezembro, 2010
Letónia

In Latvia the construction of new transport infrastructure objects or reconstruction of existing ones increasingly generates necessity to expand an area of land under auto roads (right of way), as well as activates necessity of efficiency of real property expropriation process. In frame of research the correlation between expropriated land and total area of affected land parcels have been analyzed in two different projects of road development – project of new road and project of road reconstruction.

Absorption and Translocation of Glyphosate, Metsulfuron, and Triclopyr in Old World Climbing Fern (Lygodium microphyllum)

Journal Articles & Books
Dezembro, 2010

Old World climbing fern is one of the most invasive plants in natural areas of central and southern Florida. The fern spreads across the landscape by wind-blown spores and invades isolated and undisturbed habitats such as interior portions of the Florida Everglades. Land managers in Florida have reported that multiple herbicide treatments are required to control the fern, which could indicate that herbicides do not translocate throughout the plant in long-established populations.

Quantifying long-term changes in gully networks and volumes in dryland environments: The case of Northern Ethiopia

Journal Articles & Books
Dezembro, 2013

Understanding historical and present gully development is essential when addressing the causes and consequences of land degradation, especially in vulnerable dryland environments. For Northern Ethiopia, several studies exist on the severity of gully erosion, yet few have quantified gully development. In this study, gully network and volume development were quantified over the period 1963–2010 for an area of 123km², representing the regional variability in environmental characteristics. Gully networks were mapped from small-scale aerial photographs and high-resolution satellite images.

Short-term Response of Holcus lanatus L. (Common Velvetgrass) to Chemical and Manual Control at Yosemite National Park, USA

Journal Articles & Books
Dezembro, 2015
Estados Unidos

One of the highest priority invasive species at both Yosemite and Sequoia and Kings Canyon national parks is Holcus lanatus L. (common velvetgrass), a perennial bunchgrass that invades mid-elevation montane meadows. Despite velvetgrass being a high priority species, there is little information available on control techniques. The goal of this project was to evaluate the short-term response of a single application of common chemical and manual velvetgrass control techniques. The study was conducted at three montane sites in Yosemite National Park.

Genetic consequences of forest fragmentation by agricultural land in an arboreal marsupial

Journal Articles & Books
Dezembro, 2016

CONTEXT: Increasing demands on land for agriculture have resulted in large-scale clearance and fragmentation of forests globally. In fragmented landscapes, species that tolerate or exploit the matrix will persist, while those that do not, frequently decline. Knowledge of matrix use is therefore critical to predicting extinction proneness of species in modified landscapes and defining the value of land for conservation management.
