Given the short time-frame to limit global warming, and the current emissions gap, it is critical to prioritise mitigation actions. To date, scant attention has been paid to the mitigation benefits of primary forest protection. We estimated tropical forest ecosystem carbon stocks and flows.

Socioeconomic shocks can shape future land-use trajectories. Armed conflicts are an extreme form of a socioeconomic shock, but our understanding of how armed conflicts affect land-use change is limited. Our goal was to assess land-use changes related to the 1991–1994 Nagorno-Karabakh conflict between Armenia and Azerbaijan in the Caucasus region. We classified multi-temporal Landsat imagery, mapped land-use changes during and after the conflict, and applied matching statistics to isolate the effect of the conflict from other potential drivers of land change.

As the “new rangeland paradigm” took shape in the 1990s, climatic variability in pastoral ecosystems was often discussed as “uncertainty”, and the essential mobility of pastoral systems was argued to be possible only with flexible land access rights. These context-specific principles have increasingly been globalized in analyses of diverse pastoral systems.

This paper examines the impact of land reform on agricultural productivity in Tajikistan. Recent legislation allows farmers to obtain access to heritable land shares for private use, but reform has been geographically uneven. The break-up of state farms has occurred in some areas where agriculture has little to offer but, where high value crops are grown, land reform has hardly begun. In cases where collectivized farming persists and land has not been distributed, productivity remains low and individual households benefit little from farming.

We investigated wheat price relationships between the import-dependent countries in Central Asia and the South Caucasus and the Black Sea wheat exporters to assess wheat market efficiency. This is crucial for ensuring availability and access to wheat and for reducing food insecurity. Results from linear and threshold error correction models suggested a strong influence of trade costs on market integration in Central Asia, while those costs were of minor importance in the South Caucasus.

It took scientists more than three decades to transform a perceived desertification crisis in the Sahel into a non-event. Looking beyond the Sahel, the chapters in this book provide case studies from around the world that examine the use and relevance of the desertification concept.

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 biomass we use, but also a wide

The southern and central regions of The Netherlands are part of the Northwest- European Delta Metropolis. The demands placed by modern, urban society on the agricultural sector are numerous. Not only are the environment, animal welfare, and food hygiene and quality at stake here, but also must these demands be met in a period of a structural decline in economic yields and under the permanent pressure of a shortage of available land. Intensification and increase of scale, which have characterized European agriculture for a long time, are set to continue in the future.

Spatial econometrics and analytical spatial economic modeling advanced significantly in the recent years. Yet, methodologically they are designed to tackle marginal changes in the underlying dynamics of spatial urban systems. In the world with climate change, however, abrupt sudden non-marginal changes in economic system are expected. This is especially relevant for urban development in coastal and delta areas where the probabilities of natural hazards such as catastrophic floods and hurricanes increase dramatically with climate change.
