Assessing climate change impacts on the ecohydrology of the Jinghe River basin in the Loess Plateau, China

Journal Articles & Books
Diciembre, 2013
China

Quantifying the impacts of climate change on the hydrology and ecosystem is important in the study of the Loess Plateau, China, which is well known for its high erosion rates and ecosystem sensitivity to global change. A distributed ecohydrological model was developed and applied in the Jinghe River basin of the Loess Plateau. This model couples the vegetation model, BIOME BioGeochemicalCycles (BIOME-BGC) and the distributed hydrological model, Water and Energy transfer Process in Large river basins (WEP-L).

New partnerships for managing large desert landscapes: experiences from the Martu Living Deserts Project

Journal Articles & Books

Australia

Native fauna in Australia’s arid zone has declined significantly since European settlement; however, Martu country in the Western Desert of Western Australia retains a diversity of iconic and threatened species that were once more widespread. An innovative partnership between The Nature Conservancy, BHP Billiton and the Martu people (represented by Kanyirninpa Jukurrpa – KJ) is achieving positive social, cultural, economic and environmental outcomes, which builds on funding from the Australian Government for land management on Martu country.

Understanding soil conservation decision of farmers in the gedeb watershed, ethiopia

Sudán

The aim of this study was to investigate the main factors that influence smallholders' adoption decision of soil conservation measures in the Gedeb watershed. Data from 498 household heads who live in the three districts of the watershed were analysed using the binary logistic regression model. We find that farmers need adequate cash to invest in soil conservation measures. Moreover, farmers would be more encouraged to implement soil conservation measures when they have larger areas of cropland.

Carbon management and importance in terrestrial ecosystem

Policy Papers & Briefs

Recently, researchers indicated great changes in the chemistry of atmosphere due to faster oxidation of soil organic carbon. The increases of greenhouse gasses especially CO2 concentration can affect climate, plant physiology, microbial activity, soil organic matter, and decomposition. Soil can be a store or source for atmospheric CO2. The amount of soil organic carbon stored in the soil or release to the atmosphere depends on net ecosystem productivity and heterotrophic respiration.

Droughts, floods and freshwater ecosystems: evaluating climate change impacts and developing adaptation strategies

Estados Unidos de América

Climate change is expected to have significant impacts on hydrologic regimes and freshwater ecosystems, and yet few basins have adequate numerical models to guide the development of freshwater climate adaptation strategies. Such strategies can build on existing freshwater conservation activities, and incorporate predicted climate change impacts. We illustrate this concept with three case studies. In the Upper Klamath Basin of the western USA, a shift in land management practices would buffer this landscape from a declining snowpack.

Conserving and promoting evenness: organic farming and fire‐based wildland management as case studies

Journal Articles & Books
Diciembre, 2012

Healthy ecosystems include many species (high richness) with similar abundances (high evenness). Thus, both aspects of biodiversity are worthy of conservation. Simultaneously conserving richness and evenness might be difficult, however, if, for example, the restoration of previously absent species to low densities brings a cost in reduced evenness. Using meta‐analysis, we searched for benefits to biodiversity following adoption of two common land‐management schemes: the implementation of organic practices by farmers and of controlled burning by natural‐land managers.

Integrating Land Market Feedbacks into Conservation Planning--A Mathematical Programming Approach

Journal Articles & Books
Diciembre, 2011

Nature reserves are often designated ad hoc. Despite increasing conservation efforts, loss of biodiversity is still accelerating. Considering land scarcity and demand for alternative uses, efficiency in conservation strongly correlates with efficiency in land allocation. Systematic conservation planning can effectively prioritize conservation activities. Previous studies minimize opportunity costs for given conservation targets. However, these studies assume constant marginal costs of habitat protection.

Process of recognizing the local potentials as a basis for sustainable development

Eslovenia

The article discusses the process of recognizing the local developmental and human potentials in the pilot area of Pohorje, Slovenia. Special emphasis herein is given to the need of stakeholder participation strategic plan. In the pilot area, the theoretical model was tested. As we are dealing with a wooded area, the role of forestry is highly significant in this respect, and it has been even est

ISIP - a web-based information system on integrated crop production in Germany

In modern agriculture the demand for solutions for complex problems, e.g. the optimisation of decision - making in integrated crop production, is strongly increasing. To obtain all relevant information for decision - making farmers or extension officers up to now need access to a multitude of databanks offered by different providers. In 2001 a project, funded by the German Foundation of Environmen

Rapidly restoring biological soil crusts and ecosystem functions in a severely disturbed desert ecosystem

Journal Articles & Books
Diciembre, 2016

Restoring biological soil crusts (biocrusts) in degraded drylands can contribute to recovery of ecosystem functions that have global implications, including erosion resistance and nutrient cycling. To examine techniques for restoring biocrusts, we conducted a replicated, factorial experiment on recently abandoned road surfaces by applying biocrust inoculation (salvaged and stored dry for two years), salvaged topsoil, an abiotic soil amendment (wood shavings), and planting of a dominant perennial shrub (Ambrosia dumosa).

Community perception of biodiversity conservation within protected areas in Benin

Benin

Commitment of local communities to protected areas is essential for conserving biodiversity. However, in many developing countries like Benin, former management strategies kept human from protected areas using coercion. Fortunately, more recent regimes attempt to give local populations more control on the management but little is known about local residents' perceptions, beliefs and attitudes toward the management of these areas.
