Effects of set-aside management on birds breeding in lowland Ireland

Journal Articles & Books
Décembre, 2006
Irlande
Europe

Farmland birds have suffered a severe decline in recent years throughout Europe including Ireland. Agricultural intensification is believed to be the main cause and this has led to the introduction of agri-environmental schemes, of which set-aside is a part. Bird abundance and diversity were compared between set-aside and adjacent tillage or grassland at 18 locations.

Cheatgrass Percent Cover Change: Comparing Recent Estimates to Climate Change−Driven Predictions in the Northern Great Basin

Journal Articles & Books
Décembre, 2016

Cheatgrass (Bromus tectorum L.) is a highly invasive species in the Northern Great Basin that helps decrease fire return intervals. Fire fragments the shrub steppe and reduces its capacity to provide forage for livestock and wildlife and habitat critical to sagebrush obligates. Of particular interest is the greater sage grouse (Centrocercus urophasianus), an obligate whose populations have declined so severely due, in part, to increases in cheatgrass and fires that it was considered for inclusion as an endangered species.

Nutrient delivery from the Mississippi River to the Gulf of Mexico and effects of cropland conservation

Journal Articles & Books
Décembre, 2014
Mexique

Excessive nutrients transported from the Mississippi River Basin (MRB) have created a hypoxic zone within the Gulf of Mexico, with numerous negative ecological effects. Furthermore, federal expenditures on agricultural conservation practices have received intense scrutiny in recent years. Partly driven by these factors, the USDA Conservation Effects Assessment Project (CEAP) recently completed a comprehensive evaluation of nutrient sources and delivery to the Gulf.

Rearranging agricultural landscapes towards habitat quality optimisation: In silico application to pest regulation

Journal Articles & Books
Décembre, 2016

Modern agriculture suffers from its dependence on chemical inputs and subsequent impacts on health and environment. Alternatively, protecting crops against pests can be achieved through the reinforcement of regulation ecological services. Our work propounds a data-driven methodological framework to derive relevant agricultural landscape rearrangements enhancing populations of beneficial organisms regulating pests.Building on spatialised entomological and geographic data, we developed a parsimonious reaction–diffusion model describing the population dynamics of beneficial organisms.

The analysis on the change of farming lands in the territory of middle Lithuania

Land means the basic part of the natural environment, the basic instrument of human life, activity and immovable property, which is being disposed of in the process of land relation. Land should be used when coordinating private and public interests as well as environment protection requirements.

Surface soil water content spatial organization within irrigated and non-irrigated agricultural fields

Journal Articles & Books
Décembre, 2012

Understanding soil water content, θ, variability is important for monitoring and modeling of land surface processes as well as land and water management practices. With regards to in situ θ probes, it is sometimes assumed that a single local measurement can represent the larger domain, mostly for practical reasons. But there is a substantial amount of variability in θ at the field scale.

Water for agriculture: challenges and opportunities in a war zone

Journal Articles & Books
Décembre, 2011
Afghanistan

Wars, drought and social collapse have greatly impaired land management and agriculture production systems in the southeastern Afghanistan provinces of Khost, Paktika and Paktya. This region has long existed with limited central government influence and remains particularly unstable. A complex physical and social geography, on-going warfare, severely limited mobility and policies poorly adapted to regional realities hamper development and reconstruction.

Carbon Accumulation in the Bulk Soil and Different Soil Fractions During the Rehabilitation of Desertified Grassland in Horqin Sandy Land (Northern China)

Journal Articles & Books
Décembre, 2015
Chine

Desertification, which affects more than two-thirds of the world's arid and semi-arid regions, is a significant global ecological and environmental problem. There is a strong link between desertification of the drylands and emission of CO₂ from soil and vegetation to the atmosphere. The Horqin Sandy Land is a severely desertified area in China's agro-pastoral ecotone due to its fragile ecology, combined with unsustainable land management.

Mapping sensitivity to land degradation in Extremadura. SW Spain

Journal Articles & Books
Décembre, 2009

An assessment of sensitivity to land degradation has been carried out in the Extremadura region, SW Spain, by means of a modelling approach developed by the European Commission funded MEDALUS project (Mediterranean Desertification and Land Use) which identifies such areas on the basis of an index (Environmentally Sensitive Area index, ESA index) that incorporates data on environmental quality (climate, vegetation, soil) as well as anthropogenic factors (management).
