Symposium on Agriculture in Transition: Why Did the Communist Party Reform in China, but Not in the Soviet Union? The Political Economy of Agricultural Transition

Mars, 2012
Chine

The dramatic transition from Communism to market economies across Asia and Europe started in the Chinese countryside in the 1970s. Since then more than a billion of people, many of them very poor, have been affected by radical reforms in agriculture. However, there are enormous differences in the reform strategies that countries have chosen. This paper presents a set of arguments to explain why countries have chosen different reform policies.

Sources of Mistrust: An Experimental Case Study of a Central Asian Water Conflict

Mars, 2012
Asie central

With the disintegration of the USSR a conflict arose between Kyrgyzstan, Uzbekistan and Kazakhstan over the transboundary Syr Darya river. Upstream Kyrgyzstan controls the Toktogul reservoir which generates hydropower demanded mainly in winter for heating. Downstream Uzbekistan and Kazakhstan need irrigation water in summer, primarily to grow an export crop (cotton). Regional agreements obliging Kyrgyzstan to higher summer discharges in exchange for fossil fuel transfers from downstream riparians in winter have been unsuccessful, due to lack of trust between the parties.

The Economics of Soil Fertility Management in Malawi

Mars, 2012
Malawi

We estimated a normalized translog yield-response model using African farm-household survey data to compare the yield of smallholder maize production under integrated soil fertility management (ISFM) and chemical-based soil fertility management. Controlling for other factors, maize yield responses were higher under ISFM. Results suggest ISFM practices would significantly improve the profitability of smallholder maize production, especially under escalating fertilizer prices.

State and Trends of the Carbon Market 2006 : Update, January 1-September 30, 2006

Mai, 2013

Carbon transactions are defined as purchase contracts or ERPAs (Emission Reductions Purchase Agreements) whereby one party pays another party in return for greenhouse gas (GHG) emissions reductions that the buyer can use to meet its compliance or corporate citizenship - objectives vis-a-vis GHG mitigation. Payment is made using one or more of the following forms: cash, equity, debt, or in-kind contributions.

State and Trends of the Carbon Market 2006 : A Focus on Africa

Mai, 2013
Afrique

Many African countries have thin energy and industrial sectors with limited opportunities to reduce carbon emissions, certainly relative to countries such as China and India. Carbon sequestration from avoided deforestation and from agriculture--potentially important areas for climate mitigation and important in many African economies--has been systematically excluded from the Clean Development Mechanism (CDM).

Demand for Piped and Non-piped Water Supply Services : Evidence from Southwest Sri Lanka

Mars, 2012
Sri Lanka

In many countries, water supply is a service that is seriously underpriced, especially for residential consumers. This has led to a call for setting cost recovery policies to ensure that the tariffs charged for water supply cover the full cost of service provision. Identification of factors driving piped and non-piped water demand is a necessary prerequisite for predicting how consumers will react to such price increases.

Does Rising Landlessness Signal Success or Failure for Vietnam's Agrarian Transition?

Mars, 2012
Viet Nam

In the wake of reforms to establish a free market in land-use rights, Vietnam experienced a pronounced rise in rural landlessness. To some observers this is a harmless by-product of a more efficient economy, while to others it signals the return of the pre-socialist class structure, with the rural landless at the bottom of the economic ladder. We study the issue empirically using four household surveys spanning 1993-2004. Although we find rising landlessness amongst the poor, the post-reform landlessness rate tends to be higher for the non-poor.

State and Trends of the Carbon Market 2009

Mai, 2013

Over the past year, the global economy has cooled significantly, a far cry from the boom just a year ago in various countries and across markets. At the same time, the scientific community communicated the heightened urgency of taking action on climate change. Policymakers at national, regional, and international levels have put forward proposals to respond to the climate challenge. The most concrete of these is the adopted European Union (EU) climate and energy package (20 percent below 1990 levels by 2020), which guarantees a level of carbon market continuity beyond 2012.

World Development Indicators 2008

Octobre, 2012
Global

Release of the final report of the International Comparison Program (ICP) and publication of new estimates of purchasing power parities (PPPs) in World Development Indicators 2008 are an important statistical milestone. The estimates offer a consistent and comprehensive set of data on the cost of living in developed and developing countries, the first since 1997, when the results of the previous ICP data collection were published in World Development Indicators. The 2005 data cover 146 countries and territories, 29 more than the last round in 1993, and many for the first time.

Transport on a Human Scale

Mars, 2012

An efficient and affordable access to
jobs, education and services is considered a fundamental
element for development. However, the mobility conditions in
the cities have deteriorated because of the increasing
motorization and urbanization. The number of new cars that
enter the cities every year outpaces the construction of new
roads, aggravating the existing congestion issues.
Therefore, the urban models that revolve around highways and

Is Irrigation Rehabilitation Good for Poor Farmers? An Impact Evaluation of a Non-experimental Irrigation Project in Peru

Mars, 2012
Pérou

This paper analyses the effect of a set of irrigation rehabilitation projects conducted over the last 10 years in Peru. The projects were conducted without the aim or the tools for a full-fledged impact evaluation. Nevertheless, this paper attempts an evaluation through the use of alternative data sources such as household surveys and geographic information, a strategy of identification of beneficiaries and control households based on spatial proximity to the projects' sites, and an econometric approach consisting of a double-differencing technique.
