Reconstructing the dynamics and drivers of late Quaternary megafaunal extinctions requires direct radiometric date series that are assessed within probabilistic statistical frameworks. Extinction chronologies poorly understood for many tropical regions, including Madagascar, which had a diverse, now-extinct Holocene large vertebrate fauna “megaherbivore” guild endemic hippopotami elephant birds...

Adverse changes in rangeland vegetation can be considered as one of the criteria for land degradation. Some of these changes can be evaluated through monitoring the spatial changes of landscape parameters. This study aimed to investigate the landscape changes in Kezab rangelands of Yazd province, central Iran. Landsat satellite images of 1990, 2002, and 2013, and landscape metrics including Tot...

Water as one of the most essential natural elements of landscape and consequently urban landscape from yesterday till today has had a great impact on the formation and effectiveness of urban spaces and its various effects have always stimulated human tendency towards beauty. It should be noted that the existential values ​​of water are not merely aesthetic, rather it goes back to the deepest an...

Climate Change policies are playing an ever-increasing role in global development strategies and their implementation gives rise to often-unforeseen social conflicts and environmental degradations. A landscape approach to analyzing forest-based Climate Change Mitigation policies (CCM) and land grabs in the Prey Lang Forest landscape, Cambodia revealed two Korea-Cambodia partnership projects des...

Peri-urban areas constitute an enormous resource in terms of natural capital, landscape heritage and economic activities, but, at the same time, they are often affected by physical socio-economic degradation, drawing attention decision makers planners. Many studies have focused on these contexts both suburbs, with a close dependence urban centers, new land typologies. The present paper focuses ...

Biological activity can accelerate soil processes and can thus have profound effects on weathering and the transformation of phosphorus (P). Here we show that the transformation of P is closely linked to soil development across an about 9000 years old soil chronosequence formed through glacial rebound. Easily weathered forms of P such as apatite are rapidly lost from the surface mineral horizon...

The objective of this study is to better understand the complexity of deforestation processes in southern Cameroon by testing a multivariate, spatial model of land-cover change trajectories associated with deforestation. The spatial model integrates a spectrum of independent variables that characterize land rent on a spatially explicit basis. The use of a time series of high-spatialresolution r...

In Zimbabwe, a broad-ridge and broad-furrow tillage system was promoted by the state, scientists and a nongovernmental organisation for its presumed agronomic and environmental viability and economic returns for small farmers. Zungwi vlei, a wetland of value to the community was transformed from a common use natural resource into a limited access broad-ridge and broad-furrow irrigation landscap...

Multi-objectivization represents a current and promising research direction which has led to the development of more competitive search mechanisms. This concept involves the restatement of a single-objective problem in an alternative multi-objective form, which can facilitate the process of finding a solution to the original problem. Recently, this transformation was applied with success to the...
