Land change in the Greater Antilles differs markedly among countries because of varying socioeconomic histories and global influences. We assessed land change between 2001 and 2010 in municipalities (second administrative units) of Cuba, Dominican Republic, Haiti, Jamaica, and Puerto Rico. Our analysis used annual land-use/land-cover maps derived from MODIS satellite imagery to model linear change in woody vegetation, mixed-woody/plantations and agriculture/herbaceous vegetation. Using this approach, we focused on municipalities with significant change (p ≤ 0.05).
Local Perception of Risk to Livelihoods in the Semi-Arid Landscape of Southern Africa
The United Nations and Intergovernmental Panel on Climate Change deem many regions of southern Africa as vulnerable landscapes due to changing climatic regimes, ecological conditions, and low adaptive capacity. Typically in highly vulnerable regions, multiple livelihood strategies are employed to enable sustainable development. In Botswana, livelihood strategies have diversified over time to include tourism and other non-agricultural activities. While such diversification and development have been studied, little is known about how locals perceive livelihood risks.
Re-Thinking the Role of Compensation in Urban Land Acquisition: Empirical Evidence from South Asia
Planned efforts to relocate human populations often entail protracted struggles over the terms on which local populations may be compensated for the loss of land, assets and livelihoods. In many instances, compensation has been established on the basis of historical market value, which in effect excludes stakeholders (e.g., encroachers, landless laborers, sharecroppers, etc.) whose livelihoods are adversely affected by land acquisition. Establishing ways of recognizing and compensating the loss of informal land and livelihood is therefore a pressing policy priority.
Historical and Contemporary Geographic Data Reveal Complex Spatial and Temporal Responses of Vegetation to Climate and Land Stewardship
Vegetation and land-cover changes are not always directional but follow complex trajectories over space and time, driven by changing anthropogenic and abiotic conditions. We present a multi-observational approach to land-change analysis that addresses the complex geographic and temporal variability of vegetation changes related to climate and land use.
Multifunctional Rangeland in Southern Africa: Managing for Production, Conservation, and Resilience with Fire and Grazing
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 across space and through time to understand the effects of rangeland management practices on biodiversity and ecosystem services in an era of global climate change.
