Using Remote Sensing to Quantify Vegetation Change and Ecological Resilience in a Semi-Arid System

Cui, Xia; Gibbes, Cerian; Southworth, Jane; Waylen, Peter - In: Land 2 (2013) 2, pp. 108-130

This research extends upon land cover change studies by incorporating methodological approaches, which are compatible with heterogeneous ecosystems, are able to link landscape changes to system processes, such as climate change, and provide potential linkages to concepts of ecological...

Modeling Soil and Woody Vegetation in the Senegalese Sahel in the Context of Environmental Change

Brandt, Martin; Grau, Tobias; Mbow, Cheikh; Samimi, Cyrus - In: Land 3 (2014) 3, pp. 770-792

Climatic stress and anthropogenic disturbances have caused significant environmental changes in the Sahel. In this context, the importance of soil is often underrepresented. Thus, we analyze and discuss the interdependency of soil and vegetation by classifying soil types and its woody cover for...

Mapping Urban Transitions Using Multi-Temporal Landsat and DMSP-OLS Night-Time Lights Imagery of the Red River Delta in Vietnam

Castrence, Miguel; Nong, Duong H.; Tran, Chinh C.; … - In: Land 3 (2014) 1, pp. 148-166

The urban transition that has emerged over the past quarter century poses new challenges for mapping land cover/land use change (LCLUC). The growing archives of imagery from various earth-observing satellites have stimulated the development of innovative methods for change detection in long-term...

Land Saturation in SE Niger: Triangulating Qualitative and Quantitative Information for Critical Assessment of Land Use Trajectories

Reenberg, Anette; Maman, Issoufou; Moussa, Ibrahim Bouzou; … - In: Land 2 (2013) 3, pp. 508-533

The paper analyzes land use changes, notably cropland expansion, in SE-Niger from the mid-1980s to 2011. It scrutinizes land use trajectories and investigates how cultivation shifts between dune landscapes and valleys (bas-fonds) in response to climate, population pressure, and sociocultural...

Integrating Land Change Science and Savanna Fire Models in West Africa

Laris, Paul - In: Land 2 (2013) 4, pp. 609-636

Fire is a key component of many land use systems and a determinant of land change. There is a growing concern that climate change will cause more catastrophic fires, but in many areas the impacts will be mediated by human land use practices. In African savannas, for example, fires are frequent...

Multi-Layer Assessment of Land Use and Related Changes for Decision Support in a Coastal Zone Watershed

Gitau, Margaret; Bailey, Nathaniel - In: Land 1 (2012) 1, pp. 5-31

In order to address the challenges in coastal regions, there is the need to understand the extent and impacts of past changes and their implications for future management. Land use data and remotely-sensed imagery are often used to provide insights into these changes. Often, however, existing...

Multifunctional Rangeland in Southern Africa: Managing for Production, Conservation, and Resilience with Fire and Grazing

McGranahan, Devan Allen; Kirkman, Kevin P. - In: Land 2 (2013) 2, pp. 176-193

Residents of Southern Africa depend on rangeland for food, livelihoods, and ecosystem services. Sustainable management of rangeland ecosystems requires attention to interactive effects of fire and grazing in a changing climate. It is essential to compare rangeland responses to fire and grazing...
