Effects of Land Use Change on Soil Carbon Storage and Water Consumption in an Oasis-Desert Ecotone

Journal Articles & Books
Décembre, 2014
Chine

Land use and ecosystem services need to be assessed simultaneously to better understand the relevant factors in sustainable land management. This paper analyzed land use changes in the middle reach of the arid Heihe River Basin in northwest China over the last two decades and their impacts on water resources and soil organic carbon (SOC) storage.

Degradation of cultivated bench terraces in the Three Gorges Area: Field mapping and data mining

Journal Articles & Books
Décembre, 2013

Due to resettlements, construction of new infrastructure, and new land reclamation the rapid agricultural changes in the Three Georges Area (TGA) in Central China are expected to force the degradation of the cultivated terraced landscape. Consequently, increased soil erosion can hamper a sustainable land management in the mountainous TGA. This paper presents the model framework TerraCE (Terrace Condition Erosion) for determining the causes for different terrace conditions and terrace degradation based on field surveys and spatial data mining.

Dating and quantification of erosion processes based on exposed roots

Journal Articles & Books
Décembre, 2013

Soil erosion is a key driver of land degradation and heavily affects sustainable land management in various environments worldwide. An appropriate quantification of rates of soil erosion and a localization of hotspots are therefore critical, as sediment loss has been demonstrated to have drastic consequences on soil productivity and fertility.

Nutrient stocks and phosphorus fractions in mountain soils of Southern Ecuador after conversion of forest to pasture

Journal Articles & Books
Décembre, 2013

Understanding pasture degradation processes is the key for sustainable land management in the tropical mountain rainforest region of the South Ecuadorian Andes. We estimated the stocks of total carbon and nutrients, microbial biomass and different P fractions along a gradient of land-uses that is typical of the eastern escarpment of the Cordillera Real i.e., old-growth evergreen lower montane forest, active pastures (17 and 50 years-old), abandoned pastures 10 and 20 years old with bracken fern or successional vegetation.

Channelling science into policy: Enabling best practices from research on land degradation and sustainable land management in dryland Africa

Journal Articles & Books

Afrique

Demands are increasing for scientific research to be explicitly and demonstrably policy relevant. Research funders are requiring greater returns on their investments and scientists are expected to demonstrate clearly how their research can inform policy and regulation to deliver positive consequences for societal, economic and environmental wellbeing.

systematic map of ecosystem services assessments around European agroforestry

Journal Articles & Books
Décembre, 2016
Europe

Agroforestry offers proven strategies as an environmentally benign and ecologically sustainable land management practice to promote ecosystem services. In this literature review, we systematically consider the agroforestry and ecosystem services literature with the aim to identify and catalogue the knowledge field and provide the first systematic synthesis of ecosystem services research in relation to European agroforestry. We reviewed 71 scientific publications from studies conducted in farmland and forest ecosystems with various types of agroforestry management.

Farmers’ livelihood assets and adoption of sustainable land management practices in north-western highlands of Ethiopia

Journal Articles & Books
Décembre, 2013
Éthiopie

In Ethiopia, farmers’ adoption and continued use of introduced land management technologies have not been widespread to reduce soil erosion and soil fertility depletion to an acceptable level. An important set of factors in farmers’ use of improved agricultural technologies is generally known to be their possession of livelihood assets. This study examines the influence of ownership of livelihood assets in farmers’ decisions to use cattle manure as land improvement technology, which is currently being promoted by Ethiopia’s agricultural extension system.

Land-use and land-cover change and its environmental implications in a tropical highland watershed, Ethiopia

Journal Articles & Books
Décembre, 2013
Éthiopie

This study analysed long-term land-use and land-cover change (LUCC) in a highland watershed covering an area of about 154 km² in the Blue Nile basin of Ethiopia. Two sets of panchromatic aerial photographs (1957 and 1982) and a Landsat TM image (2001) were the main input data from which three land-use and land-cover maps were produced by employing geographical information systems/remote sensing techniques. These data were complemented by some socio-economic data that were generated by using household survey, key-informant interview and group discussion methods.

Phytoremediation, a sustainable remediation technology? II: Economic assessment of CO₂ abatement through the use of phytoremediation crops for renewable energy production

Journal Articles & Books
Décembre, 2012

Phytoremediation could be a sustainable remediation alternative for conventional remediation technologies. However, its implementation on a commercial scale remains disappointing. To emphasize its sustainability, this paper examines whether and how the potential economic benefit of CO₂ abatement for different crops used for phytoremediation or sustainable land management purposes could promote phytotechnologies. Our analysis is based on a case study in the Campine region, where agricultural soils are contaminated with mainly cadmium.

development of soil and water conservation policies and practices in five selected countries from 1960 to 2010

Since the 1930s there has been worldwide concern about the effects and impacts of land degradation. After the problems experienced in the Dust Bowl in the USA, much attention was paid to soil and water conservation in both developed and developing countries. Initially Governments stimulated the establishment of physical control measures, such as terraces, check dams and reforestation. This was achieved through top-down regulations, and Forestry Departments were often in charge of the implementation.

Developing robust field survey protocols in landscape ecology: a case study on birds, plants and butterflies

Journal Articles & Books
Décembre, 2015

Sustainable land management requires scientists to provide reliable data on diversity distribution patterns. Resource restrictions limit the affordable sampling effort, both with respect to number of survey sites and amount of effort per site. We compared different levels of survey effort in a case study in Central Romania, varying the number of repeats per site and number of survey sites. Target taxa were plants, birds and butterflies. For plants, we surveyed three 10 m²plots and ten plots of 1 m²at each site.
