Aquarius satellite observations over land offer a new resource for measuring soil moisture from space. Although Aquarius was designed for ocean salinity mapping, our objective in this investigation is to exploit the large amount of land observations that Aquarius acquires and extend the mission…
Political reactions ‘from below’ to global land grabbing have been vastly more varied and complex than is usually assumed. This essay introduces a collection of ground- breaking studies that discuss responses that range from various types of organized and everyday resistance to demands for…
Whether aggravated agricultural drought in the Sahel is related to a changing climate (meteorological drought, i.e., deficit of rainfall or unfavourable rainfall distribution) or to land use and land degradation (soil-water drought, i.e., decreased water infilitration and water holding capacity…
Global trends in pollinatorâdependent crops have raised awareness of the need to support managed and wild bee populations to ensure sustainable crop production. Provision of sufficient forage resources is a key element for promoting bee populations within human impacted landscapes,…
AIM: To evaluate trend analysis of earth observation (EO) dense time series as a new way of describing and mapping changes in ecosystem functioning at regional to global scales. Spatio‐temporal patterns of change covering 1982–2011 are discussed in the context of changes in land use and land…
Global defense spending is $US1753 billion annually or approximately 2.5% of the world GDP. Significant time and resources is spent in training 28 million defense personnel worldwide. Much of this training on land takes place within specifically designated military training areas (MTAs).…
Global climate and land use changes could strongly affect soil erosion and the capability of soils to sustain agriculture and in turn impact regional or global food security. The objective of our study was to develop a method to assess soil sustainability to erosion under changes in land use and…
Fertile soils are an essential building block for human existence on Earth. The degradation of soils and land, in this regard, poses significant challenges for the well-being and food security of all the people around the world. Moreover, soils provide not only food, fiber, and many types of…
Without healthy soils, it is not possible to produce healthy food. But soils do not just produce food: they
do many other things too. They filter rainwater and turn it into clean drinking water. They regulate the climate, for after the oceans, the soil is the world’s largest carbon sink:…
In a world grappling with the challenges of food insecurity, climate change, landscape degradation, and rural poverty, regreening offers a path forward, especially in dryland areas. The transformation of degraded landscapes—restoring productivity and increasing resilience through the widespread…

The Post-2015 Agenda must address the structural factors that undermine sustainable development. It is widely recognised that secure and equitable rights to land and natural resources are central to this effort. Land rights empower people and provide a sense of dignity. They enhance food…
