Mapping Ecological Processes and Ecosystem Services for Prioritizing Restoration Efforts in a Semi-arid Mediterranean River Basin

Journal Articles & Books
December, 2014
Spain

Semi-arid Mediterranean regions are highly susceptible to desertification processes which can reduce the benefits that people obtain from healthy ecosystems and thus threaten human wellbeing. The European Union Biodiversity Strategy to 2020 recognizes the need to incorporate ecosystem services into land-use management, conservation, and restoration actions. The inclusion of ecosystem services into restoration actions and plans is an emerging area of research, and there are few documented approaches and guidelines on how to undertake such an exercise.

Desert Plant Communities in Human‐Made Patches‐‐Implications for Management

Journal Articles & Books
December, 1994
Israel

We measured productivity and diversity of annual plant communities in human—made pits and mounds (20 ° 30 ° 100 cm) in the Northern Negev of Israel. We differentiated the species according to propagule size, dispersal mode, and geographical distribution in Israel. Our results in 28 experimental units containing a pit, a mound, and a portion of the undisturbed surrounding "matrix" showed that species richness, total plant density, and biomass yield were higher in the pits and mounds than in the matrix.

Combating Aeolian Desertification in Northern China

Journal Articles & Books
December, 2015
China

Progress in combating aeolian desertification (land degradation resulting from wind erosion) has been achieved in an agro‐pastoral ecotone of northern China since the mid‐1980s. This paper reviews three common measures used to combat and control aeolian desertification in such regions. In addition, it introduces a case study on the recovery of a degraded semi‐arid ecosystem to provide regional lessons and support theoretical and practical approaches to desertification prevention and reversal on a global scale.

Quantitative Mapping and Assessment of Environmentally Sensitive Areas to Desertification in Central Iran

Journal Articles & Books
December, 2016
Iran

Desertification is one of the main environmental and also social and economic problems facing Iran. Seventeen out of 31 Iranian provinces, which are home to approximately 70% of the total population, are affected by desertification. This study aimed to use geographic information system (GIS) and fuzzy logic for mapping environmentally sensitive areas to desertification based on Mediterranean Desertification and Land Use approach in Isfahan province, central Iran.

Combating desertification in China: Past, present and future

Journal Articles & Books
December, 2013
China

China is a developing country plagued by a long-term and large-scale desertification, which causes serious environmental problems. At the same time, China also has a long history of fighting desertification, especially in the recent decades. Thus, we think China's experience and lessons may be very important and useful for other developing countries to promote the degradation mitigation and life improvement.

Differential field response of two Mediterranean tree species to inputs of sewage sludge at the seedling stage

Journal Articles & Books
December, 2011

Land degradation and desertification is a common feature in Mediterranean landscapes due to extensive and intensive land use and natural or man induced disturbances. The ecosystem may need external inputs to recover its composition and function as soils are often impoverished and vegetal key stone species lost. We evaluated the effects of the application of fresh and air-dried biosolids in the establishment and morphological and physiological performance of seedlings of Pinus halepensis and Quercus ilex under dry Mediterranean field conditions.

case of urban sprawl in Spain as an active and irreversible driving force for desertification

Journal Articles & Books
December, 2013
Spain

The United Nations Convention to Combat Desertification (UNCCD) does not distinguish between natural and human drivers, and between active and inherited desertification. Partly as a result of these ambiguities the UNCCD has attracted a low level of international attention. As the Spanish case study shows, this vagueness hinders the implementation of effective strategies to combat this global challenge.

Multi‐Scale Anthropogenic Driving Forces of Karst Rocky Desertification in Southwest China

Journal Articles & Books
December, 2015
China

Karst rocky desertification (KRD) is a type of land degradation especially prominent in southwest China. This article analyzes the anthropogenic driving forces of KRD at two scales: rural locality and its macro socio‐economic circumstances. At the rural locality scale, the intensive human pressure on land because of a large and fast growing population and unsustainable land use are identified to be the reason for KRD. However, more radical driving forces lie in the farmers' disadvantages in social‐economic circumstances, which compel them to overuse rural land.

Climate change and impact of desertification or soil/ land degradation in Turkey, combating desertification

Journal Articles & Books
December, 2008
Turkey

The total arable land of Turkey is about 28,054,000 ha. The main income of the country is agriculture and agriculture based industry. However, the prime soils cover only 17.5% of the total land surface and the productivity of the rest of the soils is limited by topographical, chemical (e.g. high calcium carbonate content, alkalinity and low organic matter), and physical (e.g. water logging, texture) attributes. The diverse topography along with deforestation and unsuitable tillage and irrigation management has been inducing the rate of erosion in the country for centuries.

Monitoring desertification in a Savannah region in Sudan using Landsat images and spectral mixture analysis

Journal Articles & Books
December, 2012
Sudan

Two Landsat images, acquired in 1987 and 2008, were analyzed to evaluate desertification processes in central North Kurdufan State (Sudan). Spectral Mixture Analysis (SMA) and multitemporal comparison techniques (change vector analysis) were applied to estimate the long-term desertification/re-growing of vegetation cover over time and in space. Site-specific interactions between natural processes and human activity played a pivotal role in desertification. Over the last 21 years, desertification significantly prevailed over vegetation re-growth, particularly in areas around rural villages.
