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.

Effects of Management Legacies on Stream Fish and Aquatic Benthic Macroinvertebrate Assemblages

Journal Articles & Books
Diciembre, 2014

Fish and benthic macroinvertebrate assemblages often provide insight on ecological conditions for guiding management actions. Unfortunately, land use and management legacies can constrain the structure of biotic communities such that they fail to reflect habitat quality.

Determination of potential grapevine (Vitis spp.) cultivation areas of Turkey based on topographic and climatic factors by using Geographic Information Systems (GIS) Techniques

Policy Papers & Briefs
Diciembre, 2015
Turquía

Turkey is homeland of the grapevine (Vitis spp.), one of the most important agricultural products in the World. Our country, having the favorable climatic conditions for viticulture, has an important role among the viticulture farming countries of the World. The objective of this study is to determine potential growing areas of grape in Turkey by using Geographic Information Systems techniques based on topographic and climatic factors. It is important to efficiently use of our limited arable lands from the agricultural point of view.

Quantifying surface albedo and other direct biogeophysical climate forcings of forestry activities

Journal Articles & Books
Diciembre, 2015

By altering fluxes of heat, momentum, and moisture exchanges between the land surface and atmosphere, forestry and other land‐use activities affect climate. Although long recognized scientifically as being important, these so‐called biogeophysical forcings are rarely included in climate policies for forestry and other land management projects due to the many challenges associated with their quantification.

Livelihood strategies and land use changes in response to conservation: Pitfalls of community-based forest management in Madagascar

Journal Articles & Books
Diciembre, 2011
Madagascar

Faced with the low success rates of protected areas in conserving natural forests and supporting rural development, the Malagasy government recently chose to transfer forest resource management to local communities. Feedback about the implementation of this new policy suggests that agriculture continues to drive deforestation. This article explores farmers' household livelihood strategies and land use changes in response to changing forest access rules arising from community-based land management.

Large‐scale Modeling of Soil Erosion with RUSLE for Conservationist Planning of Degraded Cultivated Brazilian Pastures

Journal Articles & Books
Diciembre, 2016

Pasture degradation is one of the major environmental and economic problems of Brazilian livestock production. Based on the estimates of soil loss in 140,297 km² pasturelands of Goiás State and the Federal District, the effects of land use and management and conservation practices on soil erosion by water were evaluated. Soil loss was estimated with the empirical revised universal soil loss equation model under four scenarios of land use and management of pastures and the implementation of terraces. The effects of converting hilly areas into permanently preserved areas were also evaluated.

Microbial and Enzyme Activities of Saline and Sodic Soils

Journal Articles & Books
Diciembre, 2016

Salinization and sodication are abiotic soil factors, important hazards to soil fertility and consequently affect the crop production. Soil salinization is of great concern for irrigated agriculture in arid and semi‐arid regions of the world; sodicity is characterized by an excessively high concentration of sodium (Na) in their cation exchange system. In recent times, attention has been turned to study the impacts of these factors (salinity and sodicity) on soil microbial activities.

Ecosystem service evaluation to support land-use policy

Journal Articles & Books
Diciembre, 2012

Regular economic activity takes into account ecosystem goods and services that are exchanged for money in the market (e.g. food, fibre, water) but normally ignores more intangible ones left away from market transactions (e.g. soil protection, climate regulation, disturbance control, habitat provision), even in cases when they become irreversibly impaired.

Spatial complexity and ecosystem services in rural landscapes

Journal Articles & Books
Diciembre, 2012

Despite general agreement on antagonist relationships between ecosystems capacity to simultaneously sustain the availability of regulating services and agricultural production, it is not clear how these tradeoffs operate in response to complexity loss at the rural landscapes level. Here we present a novel evaluation framework of ecosystem services (ES) and pose different response models to landscape complexity.
