Scenario analysis for regional decision-making on sustainable multifunctional land uses

Journal Articles & Books
Décembre, 2014

Land-use patterns are influenced by both top-down and bottom-up (local) factors, with their interactions varying in both space and time. This provides a major challenge to decision-making for sustainable multifunctional landscapes. A cross-scale scenario structure has been developed to integrate top-down and bottom-up context based upon the familiar IPCC Special Report on Emission Scenarios framework.

Miami-Dade County's Environmentally Endangered Lands Covenant Program: Creating Protected Areas on Private Lands via Financial Incentives

Journal Articles & Books
Décembre, 2014

We review Miami-Dade County's Environmentally Endangered Lands (EEL) Covenant Program as a means to create protected areas on private property via financial incentives. Such incentives go a step beyond regulatory and fee simple approaches to conservation. The program is codified under Chapter 25B, Article II, of the Miami-Dade County Code as authorized by section 193.501, Florida Statutes.

Assessing Degradation of Abandoned Farmlands for Conservation of the Monte Desert Biome in Argentina

Journal Articles & Books
Décembre, 2014
Argentine

Land abandonment is a major issue worldwide. In Argentina, the Monte Desert is the most arid rangeland, where the traditional conservation practices are based on successional management of areas excluded to disturbances or abandoned. Some areas subjected to this kind of management may be too degraded, and thus require active restoration. Therefore, the aim of this study was to assess whether passive succession-based management is a suitable approach by evaluating the status of land degradation in a protected area after 17–41� years of farming abandonment.

Implications of Spatial Data Variations for Protected Areas Management: An Example from East Africa

Afrique orientale

Geographic information systems and remote sensing technologies have become an important tool for visualizing conservation management and developing solutions to problems associated with conservation. When multiple organizations separately develop spatial data representations of protected areas, implicit error arises due to variation between data sets.

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

Journal Articles & Books
Décembre, 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.

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

Journal Articles & Books
Décembre, 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.

Evaluating the Impact of Distance Measures on Deforestation Simulations in the Fluvial Landscapes of Amazonia

Journal Articles & Books
Décembre, 2014

Land use and land cover change (LUCC) models frequently employ different accessibility measures as a proxy for human influence on land change processes. Here, we simulate deforestation in Peruvian Amazonia and evaluate different accessibility measures as LUCC model inputs. We demonstrate how the selection, and different combinations, of accessibility measures impact simulation results. Out of the individual measures, time distance to market center catches the essential aspects of accessibility in our study area.

Predicting climate change effects on surface soil organic carbon of Louisiana, USA

États-Unis d'Amérique

This study aimed to assess the degree of potential temperature and precipitation change as predicted by the HadCM3 (Hadley Centre Coupled Model, version 3) climate model for Louisiana, and to investigate the effects of potential climate change on surface soil organic carbon (SOC) across Louisiana using the Rothamsted Carbon Model (RothC) and GIS techniques at the watershed scale.

Projecting future crop productivity for global economic modeling

Journal Articles & Books
Décembre, 2014

Assessments of climate change impacts on agricultural markets and land‐use patterns rely on quantification of climate change impacts on the spatial patterns of land productivity. We supply a set of climate impact scenarios on agricultural land productivity derived from two climate models and two biophysical crop growth models to account for some of the uncertainty inherent in climate and impact models.

Assessing the changes in land use and ecosystem services in an oasis agricultural region of Yanqi Basin, Northwest China

Journal Articles & Books
Décembre, 2014

The Yanqi Basin, one of the most productive agricultural areas, has a high population density in Xinjiang, Northwest China. Land use changes, mainly driven by oasis expansion, significantly impact ecosystem services and functions, but these effects are difficult to quantify. The valuation of ecosystem services is important to clarify the ecological and environmental changes caused by agriculturalization of oasis.

What makes a swamp swampy? Water regime and the botany of endangered wetlands in western Victoria

Journal Articles & Books

Australie

Freshwater temporary wetlands are a little-studied ecosystem worldwide. They have been recognised as critically endangered in south-eastern Australia under Australian biodiversity conservation legislation. However, little has been recorded about their hydrology, functioning or biodiversity values; i.e. the factors that make them intrinsically ‘swampy’.
