Representing composition, spatial structure and management intensity of European agricultural landscapes: A new typology

Journal Articles & Books
December, 2016
Europe

Comprehensive maps that characterize the variation in agricultural landscapes across Europe are lacking. In this paper we present a new Europe-wide, spatially-explicit typology and inventory of the diversity in composition, spatial structure and management intensity of European agricultural landscapes. Agricultural landscape types were characterized at a 1km2 resolution based on Europe-wide datasets that represent land cover, landscape structure and land management intensity.

Evaluating exposure to land degradation in association with repetitive armed conflicts in North Lebanon using multi-temporal satellite data

Journal Articles & Books
December, 2014

Repetitive armed conflicts may be directly and indirectly responsible for severe biophysical modification to the environment. This, in turn, makes land more susceptible to degradation. Mapping and monitoring land degradation are essential for designing and implementing post-conflict recovery plans and informed policy decisions. The aim of this work was to evaluate the effect of repetitive armed conflicts on land degradation along the coastal zone of North Lebanon using multi-temporal satellite data.

Assessing the long-term impact of climatic variability and human activities on the water resources of a meso-scale Mediterranean catchment

Journal Articles & Books
December, 2014
France

This article addresses the critical need for a better quantitative understanding of how water resources from the Hérault River catchment in France have been influenced by climate variability and the increasing pressure of human activity over the last 50 years. A method is proposed for assessing the relative impacts of climate and growing water demand on the decrease in discharge observed at various gauging stations in the periods 1961–1980 and 1981–2010.

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

Journal Articles & Books
December, 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.

Spatial and temporal analysis of land cover changes and water quality in the Lake Issaqueena watershed, South Carolina

Journal Articles & Books
December, 2014

Monitoring changes in land cover and the subsequent environmental responses are essential for water quality assessment, natural resource planning, management, and policies. Over the last 75 years, the Lake Issaqueena watershed has experienced a drastic shift in land use. This study was conducted to examine the changes in land cover and the implied changes in land use that have occurred and their environmental, water quality impacts.

Systems scale assessment of the sustainability implications of emerging green initiatives

Journal Articles & Books
December, 2013
United Kingdom

This paper demonstrates a systems framework for assessment of environmental impacts from ‘green initiatives’, through a case study of meso-scale, anthropogenic–biogenic interactions. The following cross-sectoral green initiatives, combining the emerging trends in the North East region of the United Kingdom, have been considered – increasing the vegetation cover; decarbonising road transport; decentralising energy production through biomass plants.

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

Journal Articles & Books
December, 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.

Assessing the effect of alternative land uses in the provision of water resources: Evidence and policy implications from southern Europe

Journal Articles & Books
December, 2012
Europe

Ecosystem goods and services have been brought to the forefront of policy making all over the world. It is acknowledged that these goods and services underpin human well-being. The provision of water resources is amongst those services that have raised more attention, given its unquestionable value and global threats like climatic change. Nevertheless, the biophysical basis that determines the land-use/water interactions has been often ignored. For the formulation of sound decisions, it is necessary to extend the empirical basis that determines these complex relations.

Satellite-indicated variations in China's forests from 2001 to 2009

China

Variations of forest area and vegetation activity in China from 2001 to 2009 were investigated using the IGBP land-cover data and the EVI (Enhanced Vegetation Index) dataset derived from Moderate-Resolution Imaging Spectroradiometer (MODIS) products in the 3 years of 2001, 2005, and 2009. The area of forests in China had increased by about 10%, and the changes in EVI-indicated vegetation activity showed large regional differences. The EVI decreased between 2001 and 2005 while it increased between 2005 and 2009 in most areas of southern China.

Monitoring land-use change-associated land development using multitemporal Landsat data and geoinformatics in Kom Ombo area, South Egypt

Journal Articles & Books
December, 2012
Egypt

Due to the progressive increase in population, sustainable development of desert land in Egypt has become a strategic priority in order to meet the increasing demands of a growing population for food and housing. Such obligations require efficient compilation of accurate land-cover information in addition to detailed analysis of archival land-use changes over an extended time span. In this study, we applied a methodology for mapping land cover and monitoring change in patterns related to agricultural development and urban expansion in the desert of the Kom Ombo area.

Bridging between the regional degree and the community approaches to rurality—A suggestion for a definition of rurality for everyday use

Journal Articles & Books
December, 2012
Denmark

The territorial approach to rural development highlights the role of local actors, networks, culture, nature and landscape amenities. The Organization for Economic Co-operation and Development (OECD) definition of rurality is, however, not capable of dealing with local and community definitions of rurality, which vary from study to study. In everyday life, physical planners, rural policymakers and local rural actors need a consistent definition of rurality.

Quantification and assessment of changes in ecosystem service in the Three-River Headwaters Region, China as a result of climate variability and land cover change

China

Rapid and periodic assessment of the impact of land cover change and climate variability on ecosystem services at regional levels is essential to understanding services and sustainability of ecosystems. This study focused on quantifying and assessing the changes in multiple ecosystem services in the Three-River Headwaters Region (TRHR), China in 2000–2012.
