Land Use and Land Cover (LULC) classes defined by subjective criteria can diminish the significance of a study, hindering the reproducibility and the comparison of results with other studies. Having a standard legend for a given study area and objective could benefit a group of researchers focused on long-term or multidisciplinary studies in a given area, in the sense that they would be able to maintain class definition among different works, done by different teams.

Wildlands are increasingly lost to human development. Conservation scientists repeatedly call for protecting the remaining wildlands and expanding the land area protected in reserves. Despite these calls, conservation reserves can be eliminated through legislation that demotes their conservation status. For example, legislation introduced to the Congress of the United States recently would demote 29 Wilderness Study Areas (WSAs) from the protections afforded by their existing status.

The paper investigates whether farm dwellers in the KwaZulu-Natal (KZN) province of South Africa are subject to a “double exposure”: vulnerable both to the impacts of post-apartheid agrarian dynamics and to the risks of climate change. The evidence is drawn from a 2017 survey that was undertaken by the Association for Rural Advancement (AFRA), which is a land rights Non-Governmental Organization (NGO), of 843 farm dweller households. Data on the current living conditions and livelihoods was collected on 15.3% of the farm dweller population in the area.

Against the background of climate change, current and future provision of ecosystem services (ES) will also change. The recording of current provision potentials and its development in future is important for adapted regional planning. ES assessments are frequently carried out in the context of expert-based surveys, which have, however, revealed little information to date about uncertainties. We present a novel approach that combines the ES matrix assessment with the Delphi approach, confidence ratings, standardized confidence levels, and scenario assessment.

Since the 1990s, many peatlands that were drained for peat extraction and agriculture in Russia have been abandoned with high CO2 emissions and frequent fires, such as the enormous fires around Moscow in 2010. The fire hazard in these peatlands can be reduced through peatland rewetting and wetland restoration, so monitoring peatland status is essential. However, large expanses, poor accessibility, and fast plant succession pose as challenges for monitoring these areas without satellite images.

Pastoral mobility is seen as the most effective strategy to make use of constantly shifting resources. However, mobile pastoralism as a highly-valued strategy to manage grazing areas and exploit resource variability is becoming more complex, due to recurrent droughts, loss of forage, government-led settlement schemes, and enclosure of land for community conservation, among other reasons. Yet knowledge of how Samburu pastoralists perceive these changes, and govern and innovate in their mobility patterns and resource use, has received limited attention.

Agricultural policies have impacts on land use, the economy, and the environment and their analysis requires disaggregated data at the local level with geographical references. Thus, this study proposes a model for disaggregating agricultural data, which develops a supervised classification of satellite images by using a survey and empirical knowledge. To ensure the consistency with multiple sources of information, a minimum cross-entropy process was used. The proposed model was applied using two supervised classification algorithms and a more informative set of biophysical information.

Forest reference (emission) levels (FREL/FRLs) are baselines for REDD+, and 34 countries have submitted their FREL/FRLs to UNFCCC by January 2018. Most of them used simple historical average without considering the stages of forest transition. This research suggested that the period of calculating FREL/FRLs of simple historical average should be properly chosen if these countries are occupying multiple stages or sub-stages of forest transition.

From a Mongolian ‘super mine’ to China’s One Belt One Road, rapid infrastructural development is reforging Central Asia as an economic pivot of the future. Such development offers enticing economic benefits, but threatens fragile environments and local livelihoods. Due to the weakness of the state, the emphasis will be on citizens to hold developers accountable to their social and environmental pledges. Reports of political elites influencing the demands of popular protests call into question the ability of citizens to fulfil this function.

Increases in human population and per-capita consumption are putting enormous pressure on land resources. About 38% of the Earth’s land area is being used in agricultural production [1], with about half (ca. 31%) of the remaining land being under forest cover [2] and the other half being less suitable for agricultural production due to edaphic, topographic and/or climatic factors. Despite the fact that over the last three decades the world food production has doubled [3], about 1 in 9 people in the world is still undernourished [4].
