Land use and agricultural practices can result in important contributions to the global source strength of atmospheric nitrous oxide (N₂O) and methane (CH₄). However, knowledge of gas flux from irrigated agriculture is very limited. From April 2005 to October 2006, a study was conducted in the Aral Sea Basin, Uzbekistan, to quantify and compare emissions of N₂O and CH₄ in various annual and perennial land-use systems: irrigated cotton, winter wheat and rice crops, a poplar plantation and a natural Tugai (floodplain) forest.

The implicit hydrologic dimensions of international efforts to mitigate climate change, specifically potential impacts of the Clean Development Mechanism-Afforestation/Reforestation (CDM-AR) provisions of the Kyoto Protocol (KP) on global, regional and local water cycles, are examined. The global impact of the redistribution of water use driven by agriculture and land use change, of which CDM-AR can be a contributing factor, is a major component of ongoing global change and climate change processes.

The total arable land of Turkey is about 28,054,000 ha. The main income of the country is agriculture and agriculture based industry. However, the prime soils cover only 17.5% of the total land surface and the productivity of the rest of the soils is limited by topographical, chemical (e.g. high calcium carbonate content, alkalinity and low organic matter), and physical (e.g. water logging, texture) attributes. The diverse topography along with deforestation and unsuitable tillage and irrigation management has been inducing the rate of erosion in the country for centuries.

This article analyses the mechanism behind the changes in agricultural land use arising from climate variables, agricultural policies and socio-economic pressures. The study presented here has undertaken an integrated methodology in the estimation of future land use change in Europe. The scenarios constructed in this study include estimates not only of changes in the climate baseline, but also of possible future changes in socio-economics.

This paper explores the concept of agricultural resilience in the context of climate change relatedwater scarcity. Specifically, the impact of water scarcity on agricultural production is analyzedto derive the timing of exit decisions for farmers faced with the prospect of decliningprofitability in agriculture but increasing benefits from land rezoning in future. The prospects ofland rezoning are modeled as a poison process which may or may not be influenced by farmer’swater abstraction decisions.

Soils are a vital substrate for agricultural production, play a central role in regulating the global carbon budget, and are a valuable source of biodiversity. Yet estimates of the global area affected by soil and land degradation are continuing to increase. For decades, soil scientists have called for a legally binding, international policy framework to guide the sustainable use of soils, but a piecemeal legislative approach has prevailed instead. With over 200 international environmental agreements currently in force, there is political reluctance for another one.

Both climate and agricultural policy changes are commonly seen as important drivers for agricultural production. In this study, scenarios of climate and political change were calculated for the Upper Danube catchment area using the regional optimization model ACRE. Two political scenarios were calculated for the year 2020. One scenario assumes the continuation of the Common Agricultural Policy reform 2003 the other assumes a strong shift away from payments of the first pillar to payments of the second pillar of the CAP.

After decades of war, with a dilapidated infrastructure and millions of people dead, wounded or displaced, Vietnam could have been considered a hopeless case in economic development. Yet, it is now about to enter the ranks of middle-income countries. The obvious question is: How did this happen? This paper goes one step further, asking not which policies were adopted, but rather why they were adopted. This question is all the more intriguing because the process did not involve one group of individuals displacing another within the structure of power.

In the last two decades, across a range of countries high growth rates have reduced poverty but have been accompanied by rising inequality. This paper is motivated by this stylized fact, and by the strong distributional concerns that persist among populations and policy makers alike, despite the poverty reduction observed in official statistics where growth has been sufficiently high. This seeming disconnects frames the questions posed in this paper. Why the disconnect, and what to do about it?
