Abstract:

This study was aimed at investigating the perceptions, knowledge and understanding of desertification and its causes among decision makers in northern Namibia. The focus of investigation was on desertification and its major causes as identified in the general literature, viz. deforestation, overgrazing and overcultivation. Particular attention was given to the socioeconomic and cultural factors which are behind these perceived 'ecological' causes of desertification. Furthermore, the respondents were also engaged in the generation of solutions to the problem of desertification and its causes. D

Abstract:

Desertification is a problem occurring in arid and semiarid zones all over the world. It is a consequence of mismanagement of the land. Human activities and livestock pressure on such fragile ecosystems lead to a deterioration of the soil by increasing its salinity, lessening its moisture, and covering it with sand and dust. Aerial photographs and satellite images constitute a tool for mapping and monitoring the desertification process. Multispectral data can assist in detecting the indicators of desertification in early stages in order to plan adequate action. The improvement of the resolutio

Abstract:

Land degradation in drylands (desertification) is an issue that potentially impacts nearly half of the world's human population living on over a third of the Earth's land surface. Despite global concern of the impact of desertification on people and the environment, there is no universal method to assess and map desertification. Methods to assess desertification at the local to regional scale that can fit into a broader global desertification narrative are more appropriate. The overall objective of this thesis is to assess regional desertification using field and Earth observation data for the

Abstract:

The desert termite Gnathamitermes tubiformans and its unique foraging tubes are a common fixture in rangelands across Arizona, New Mexico, northern Mexico, and Texas. Although it is a native species and has thrived for millions of years, recent droughts have made its activity more visible and raised questions about its impact on vegetation. Since G. tubiformans prefers grasses as food, there has been a concern about competition between livestock and termites. Monitoring of desert termite activity was conducted through two experiments focusing on foraging distances and forager population sizes

However, in the new concept of desertification as a degradation process, today we are facing a new trend of desertification in the sub-humid regions with an accelerating rate because of deforestation, poor agricultural land use practice and overgrazing.

Abstract:

Mestrado em Arquitetura Paisagista - Instituto Superior de Agronomia<br>The desertification process is related to land degradation in arid, semi-arid and dry sub-humid areas resulting from climate change and human activities. The effects of desertification are notorious at local, regional, national and global scale. Land degradation can be caused by erosion, salinization, compaction and reduction of nutrients. As a consequence of land degradation there will be a disruption of biological cycles on which life depends, as well as social development problems. Nowadays it is completely neces

Abstract:

Multi-temporal remotely sensed data (MSS, TM and ETM+)were used for monitoring and mapping the desertification processes in North Kordofan State, Sudan.A liear mixture model (LMM) was adopted to analyse and the desertification proccesses by using the image endmembers. interpretation of ancillary data and field observation was adopted to verfiy the role of human impacts in the temporal changes in the study area. The findings of the study proved the powerfull of remotely sensed data in monitoring and mapping the desertification processes and come out with valuable recommendations which could con

Abstract:

This study takes an integrated approach using theories and methods from both the natural and social sciences to examine western scientific, government, NGO and local land user understandings of land degradation in Swaziland. Of key importance in the research is the United Nations Convention to Combat Desertification (UNCCD), which itself marks a new, integrated approach to sustainable development, promoting concepts of community participation and local level decision-making. Grounded in the theory of political ecology, these concepts are examined in the Swazi context. Local knowledges are inte

Abstract:

Our world is beleaguered by environmental and socioeconomic problems, such as natural resources degradation, natural hazards, climate change, unemployment, and inequality. Trade supply chains are recognised as important means to address environmental and socio-economic challenges. The world has benefited from trade in many ways, such as promoting economic growth, opening the global market for all countries, and creating jobs. However, trade is likely to increase environmental externalities at both national and global level. Trade can directly affect local environment through overexploitation o

Abstract:

Global deserts occupy one-third of the Earth's surface and contribute significantly to organic carbon storage, a process at risk in dryland ecosystems that are highly vulnerable to climate-driven ecosystem degradation. The forces controlling desert ecosystem degradation rates are poorly understood, particularly with respect to the relevance of the arid-soil microbiome. Here we document correlations between increasing aridity and soil bacterial and archaeal microbiome composition along arid to hyperarid transects traversing the Atacama Desert, Chile. A meta-analysis reveals that Atacama soil mi
