The economic value of the Upper Tuul ecosystem in Mongolia reports on a study carried out under the auspices of the World Bank and the Government of Mongolia. The goal of the study was to improve understanding about the economic value of the Upper Tuul ecosystem for Ulaanbaatar's water supplies and how this might be affected by different land and resource management options in the future.

The objective of this study is to improve understanding of the implications of climate change for the groundwater systems in coastal Bangladesh. This is achieved by: (a) obtaining available geologic, hydrologic, and geochemical information on coastal aquifers of Bangladesh; (b) developing groundwater flow and salt transport models representing general features and conditions along the coast of Bangladesh; and (c) simulating potential changes in the groundwater systems due to various aspects of human activity and climate change.

The primary objective of the Southern Gobi Regional Environmental Assessment (REA) is to provide guidance for sustainable management of environmental resources in the future development of the Southern Gobi Region (SGR), development that will be led by rapid expansion of mining.

Sustainable Land Management for Mitigation of and Adaptation to Climate Change

Reports & Research
Training Resources & Tools
Juin, 2010

The climate change (CC) caused by increase in atmospheric concentration of CO2 and other Greenhouse Gases (GHGs), can be addressed through adaptation and mitigation strategies. Adaptation consists of strategies which minimize vulnerability to CC. The objective is to increase resilience of the ecosystems and communities through adoption of specific sustainable land management (SLM) techniques that have adaptive benefits. On the other hand, the goal of mitigation strategies is to enhance soil and vegetation (land) sinks for absorbing atmospheric CO2 and to minimize net emissions.

This country note for Armenia is part of a series of country briefs that summarize information relevant to climate change and agriculture for three pilot countries in the Southern Caucasus Region, with a particular focus on climate and crop projections, adaptation options, policy development and institutional involvement. The note series has been developed to provide a baseline of knowledge on climate change and agriculture for the countries participating in the regional program on reducing vulnerability to climate change in Southern Caucasus Agricultural systems.

Land Productivity and Plot Size

This paper revisits the decades-old puzzle of the inverse plot-size productivity relationship, which states that land productivity decreases as plot size increases. Existing empirical studies on the inverse plot-size productivity relationship define land productivity or yields as self-reported production divided by plot size. This paper considers an alternative approach to estimating yields based on crop cuts.

Assessing the Permanence of Land Use Change Induced by Payments for Environmental Services

There have been few efforts to evaluate whether the positive land use changes induced by conservation interventions such as Payments for Environmental Services (PES) persist once the interventions end. Since gains achieved by conservation interventions may be lost upon termination of the program, even apparently successful interventions may not result in longterm conservation benefits, a problem known as that of permanence. This paper examines the permanence of land use changes induced by a short-term PES program implemented between 2003 and 2008 in Matiguas-Rio Blanco, Nicaragua.

Over the past 25 years, Uganda has experienced sustained economic growth, supported by a prudent macroeconomic framework and propelled by consistent policy reforms. Annual Gross Domestic Product (GDP) growth averaged 7.4 percent in the 2000s, compared with 6.5 in the 1990s. Economic growth has enabled substantial poverty reduction, with the proportion of people living in poverty more than halving from 56 percent in the 1992 to 23.3 percent in 2009. However, welfare improvements have not been shared equally; there is increasing urban rural inequality and inequality between regions.

Mission Impossible?

Research has provided robust evidence for the use of GPS technology to be the scalable gold standard in land area measurement in household surveys. Nonetheless, facing budget constraints, survey agencies often seek to measure with GPS only plots within a given radius of dwelling locations. Subsequently, it is common for significant shares of plots not to be measured, and research has highlighted the selection biases resulting from using incomplete data.

A City-Wide Approach to Carbon Finance

Urbanization and climate change will define much of the 21st century. Urbanization leads to improvement in standards of living, and through the increased density and service delivery efficiency of cities, higher growth can be achieved with lower greenhouse gas emissions. Cities and urban agglomerations house more than 50 percent of the global population and contribute more than 70 percent of Global greenhouse (GHG) emissions. As the share of urban population grows, sustainable urban development emerges as an essential component in addressing climate change.

Modeling for Watershed Management

Juin, 2010

Watershed management problems are usually quite diverse, and involve a wide range of biological, geological, chemical, and physical processes with complex human, social, and economic contexts. The working note seeks to show that computer modeling allows us to better organize, test, and refine our thinking about watershed management problems and potential solutions.
