Biophysical suitability, economic pressure and land-cover change: a global probabilistic approach and insights for REDD+

Journal Articles & Books
Décembre, 2014
Europe

There has been a concerted effort by the international scientific community to understand the multiple causes and patterns of land-cover change to support sustainable land management. Here, we examined biophysical suitability, and a novel integrated index of “Economic Pressure on Land” (EPL) to explain land cover in the year 2000, and estimated the likelihood of future land-cover change through 2050, including protected area effectiveness.

Integrating ecosystem services into spatial planning—A spatial decision support tool

Journal Articles & Books
Décembre, 2016
Suisse

Urbanization is viewed as endangering more critical habitats of global value and is more ubiquitous than any other human activity affecting biodiversity, climate, water and nutrient cycles at multiple scales. Spatial and landscape planning can help create alternative urban patterns protecting ecosystems and thus supporting the provision of needed services they provide. While many approaches exist to make the values of nature explicit, new tools are needed to interpret the vast quantity of information in an integrated assessment to support planning.

Water-related ecosystem services in Western Siberian lowland basins—Analysing and mapping spatial and seasonal effects on regulating services based on ecohydrological modelling results

Journal Articles & Books
Décembre, 2016

For discussing and planning sustainable land management of river basins, stakeholders need suitable information on spatio-temporal patterns of natural processes and human actions. This study shows an approach to use ecohydrological modelling results for assessing water-related ecosystem services in three lowland river basins in Western Siberia. Based on the results of the ecohydrological model SWAT (Soil and Water Assessment Tool, Arnold et al., 1998), simulated output variables were used as indicators for the two regulating services water flow regulation and erosion regulation.

Catchments, sub-catchments and private spaces: Scale and process in managing microbial pollution from source to sea

Journal Articles & Books
Décembre, 2011

This paper examines the implications of adopting catchment scale approaches for the sustainable management of land and water systems. Drawing on the findings of an interdisciplinary study examining how farm management practices impact on the loss of faecal indicator organisms (FIOs) and potential pathogens from land to water, the paper argues that the overwhelming focus on integration at the catchment level may risk ignoring the sub-catchment as an equally appropriate unit of hydrological analysis.

Bracken fern frond status classification in the Andes of southern Ecuador: combining multispectral satellite data and field spectroscopy

Équateur

In the anthropogenic fire-disturbed ecosystem of the San Francisco Valley in the Andes of southeastern Ecuador, dense stands of an aggressive invasive weed, the southern bracken fern (Pteridium arachnoideum and Pteridium caudatum), dominate the landscape. To secure sustainable land management in the region, a comprehensive understanding of bracken spatial-distribution patterns and life cycle dynamics is crucial.

Relationship between the weathering of clay minerals and the nitrification rate: a rapid tree species effect

Journal Articles & Books
Décembre, 2013

We compared the properties of the clay mineral fraction and the composition of soil solutions in a Fagus sylvatica coppice (native forest) and four adjacent plantations of Pseudotsuga menziesii, Pinus nigra, Picea abies and Quercus sessiliflora planted in 1976. The results revealed changes of clay fraction properties due to tree species effect. Clay samples from Douglas fir and pine stands differ when compared to other species.

Exploration of Scenarios to Support Sustainable Land Management Using Integrated Environmental Socio-economic Models

Journal Articles & Books
Décembre, 2014

Scenario analysis constitutes a valuable deployment method for scientific models to inform environmental decision-making, particularly for evaluating land degradation mitigation options, which are rarely based on formal analysis. In this paper we demonstrate such an assessment using the PESERA–DESMICE modeling framework with various scenarios for 13 global land degradation hotspots.

Participatory Evaluation of Monitoring and Modeling of Sustainable Land Management Technologies in Areas Prone to Land Degradation

Journal Articles & Books
Décembre, 2014

Examples of sustainable land management (SLM) exist throughout the world. In many cases, SLM has largely evolved through local traditional practices and incremental experimentation rather than being adopted on the basis of scientific evidence. This means that SLM technologies are often only adopted across small areas. The DESIRE (DESertIfication mitigation and REmediation of degraded land) project combined local traditional knowledge on SLM with empirical evaluation of SLM technologies.

Sustainable Land Management (SLM) Practices in Drylands: How Do They Address Desertification Threats?

Journal Articles & Books
Décembre, 2014

Managing land sustainably is a huge challenge, especially under harsh climatic conditions such as those found in drylands. The socio-economic situation can also pose challenges, as dryland regions are often characterized by remoteness, marginality, low-productive farming, weak institutions, and even conflict. With threats from climate change, disputes over water, competing claims on land, and migration increasing worldwide, the demands for sustainable land management (SLM) measures will only increase in the future.

COST action ES1104 “Arid lands restoration and combat of desertification: Setting up a drylands and desert restoration hub”

Journal Articles & Books

Europe

This paper briefly describes COST Action ES1104 “Arid lands restoration and combat of desertification: Setting up a drylands and desert restoration hub”. (COST - European Cooperation in Science and Technology) is one of the longest running European frameworks supporting cooperation among scientists and researchers across Europe.) This networking project’s focus is to provide a hub of knowledge particularly relating to the practical methods of vegetation establishment and restoration as well as sustainable land management in arid and dryland areas.

Native plant resources to optimize the performances of forest rehabilitation in Mediterranean and tropical environment: Some examples of nursing plant species that improve the soil mycorrhizal potential

Journal Articles & Books
Décembre, 2013

The overexploitation of natural resources, resulting in an increased need for arable lands by local populations, causes a serious dysfunction in the soil's biological functioning (mineral deficiency, salt stress, etc.). This dysfunction, worsened by the climatic conditions (drought), requires the implementation of ecological engineering strategies allowing the rehabilitation of degraded areas through the restoration of essential ecological services.

Simulation of land use/land cover change and its effects on the hydrological characteristics of the upper reaches of the Hanjiang Basin

Journal Articles & Books
Décembre, 2015

In any watershed, many factors influence land use/cover change (LUCC). The nonlinear relationships between these factors and LUCC are very complicated and make it difficult to build a model that is capable of accurately simulating the range of physical processes. The aim of this study was: (1) to simplify the structure of a simulation model and improve its simulation speed, and (2) evaluate the impact of land use/cover change on surface runoff and evapotranspiration.
