Spatial decision support system for assessing lake pollution hazard: southeastern pampean shallow lakes (Argentina) as a case study

Journal Articles & Books
Diciembre, 2014
Argentina

This study gives an account of the implementation of a decision support system as a logical framework for assessing lake pollution hazard. The use of this system is demonstrated with an example from two lake watersheds, each one with different land-use, soil and topographic characteristics and also management regulations for natural resource protection. Lake pollution hazard is assessed as a function of two primary topics: hydrologic and soil conditions.

Human impact on avian diversity in rural Mediterranean areas

Journal Articles & Books
Diciembre, 2015

Human activities influence the biodiversity of Mediterranean ecosystems and are involved in the transformation of natural habitats into farmland. We surveyed birds using the point count method on 288 plots at a 50-m radius in three altitudinal landscapes with different rural character in spring and autumn. The results showed that bird species richness in the study area was high (74 species). High total species richness was found in the upland rural landscape characterized by mixed land use and high landscape diversity.

Global food supply: land use efficiency of livestock systems

Journal Articles & Books
Diciembre, 2016
Global

PURPOSE: Livestock already use most global agricultural land, whereas the demand for animal-source food (ASF) is expected to increase. To address the contribution of livestock to global food supply, we need a measure for land use efficiency of livestock systems. METHODS: Existing measures capture different aspects of the debate about land use efficiency of livestock systems, such as plant productivity and the efficiency of converting feed, especially human-inedible feed, into animal products. So far, the suitability of land for cultivation of food crops has not been accounted for.

Rapid assessment of historic, current and future habitat quality for biodiversity around UK Natura 2000 sites

Journal Articles & Books
Diciembre, 2015

Changes in landscape composition and structure may impact the conservation and management of protected areas. Species that depend on specific habitats are at risk of extinction when these habitats are degraded or lost. Designing robust methods to evaluate landscape composition will assist decision- and policy-making in emerging landscapes. This paper describes a rapid assessment methodology aimed at evaluating land-cover quality for birds, plants, butterflies and bees around seven UK Natura 2000 sites.

Community’s forest dependency and its effects towards the forest resources and wildlife abundances in Sarawak, Malaysia

Journal Articles & Books
Diciembre, 2015
Malasia

Forests play an important role in the community’s livelihood, and this role has created an important relationship or mutual dependence between the forest and the community. Therefore, this study was conducted to identify the types of community’s forest dependency and to identify the effects of community’s forest dependency towards forest resources and wildlife abundance. The data were collected using the self-administered questionnaire, involving 204 community members in Bau District, Sarawak.

Sustainable agricultural residue removal for bioenergy: A spatially comprehensive US national assessment

Journal Articles & Books
Diciembre, 2013
Estados Unidos de América

This study provides a spatially comprehensive assessment of sustainable agricultural residue removal potential across the United States for bioenergy production. Earlier assessments determining the quantity of agricultural residue that could be sustainably removed for bioenergy production at the regional and national scale faced a number of computational limitations. These limitations included the number of environmental factors, the number of land management scenarios, and the spatial fidelity and spatial extent of the assessment.

Methodical approaches to the improvement of the use of lands and organization of the territory of agricultural organizations in conditions of ecologization of land use

Belarús

In the conditions of the Republic of Belarus there were presented theoretical statements and methodical approaches to the improvement of the use of lands and organization of the territory of agricultural organizations in conditions of ecologization of land use. There were formulated the notion and tasks of improvement of the use of lands of agricultural organizations.

Finding Homogeneity in Heterogeneity--A New Approach to Quantifying Landscape Mosaics Developed for the Lao PDR

Journal Articles & Books
Diciembre, 2009
Laos

A key challenge for land change science in general and research on swidden agriculture in particular, is linking land cover information to human-environment interactions over larger spatial areas. In Lao PDR, a country facing rapid and multi-level land change processes, this hinders informed policy- and decision-making. Crucial information on land use types and people involved is still lacking. This article proposes an alternative approach for the description of landscape mosaics.

Comparative studies of the distribution characteristics of rocky desertification and land use/land cover classes in typical areas of Guizhou province, China

Journal Articles & Books
Diciembre, 2014
China

The Huajiang and Hongfenghu demonstration areas represent typical karst landforms and rocky desertification landscapes in Guizhou, China. These were selected for a comparison of rocky desertification and land use cover. Based mainly on 5� m resolution Spot 5, remote sensing images, topographic maps (1:10,000) and land use maps, the intensity and extent of rocky desertification, and slope characteristics of the two areas were interpreted. Spatial overlay analysis was used to compare the land use/land cover (LULC) and rocky desertification within each.

utility of the cropland data layer for forest inventory and analysis

Journal Articles & Books
Diciembre, 2009

The Forest Service, U.S. Department of Agriculture's (USDA's) Northern Research Station Forest Inventory and Analysis program (NRS-FIA) uses digital land cover products derived from remotely sensed imagery, such as the National Land Cover Dataset (NLCD), for the purpose of variance reduction via postsampling stratification. The update cycle of the NLCD product is infrequent; NLCD 2001 was the first update since the release of NLCD 1992, and was not yet fully completed as of late 2006.

Linking Farmers’ Knowledge, Farming Strategies, and Consequent Cultivation Patterns into the Identification of Healthy Agroecosystem Characteristics at Local Scales

Tanzania

In order to identify sustainable management solutions for small-scale farmer agroecosystems, a better understanding of these dynamic forest–farmland systems, existing farming and forestry strategies, and farmer perspectives is important. We examined the relationship between agricultural land use patterns and farmers’ practices and identified existing and potential characteristics of healthy agroecosystems at local scale in the context of village communities in Zanzibar, Tanzania.
