Highlights the plight of Pacific Islanders due to rising sea levels and storm surges and the message they brought to the UN Climate Change Conference in Bali.

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.

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.

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).

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.

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.

We present the results of a framed field experiment with Ethiopian farmers that use the mountain rain forest as a common pool resource. Harvesting honey causes damage to the forest, and open access leads to over-harvesting. We test different mechanisms for mitigating excessive harvesting: a collective tax with low and high tax rates, and a tax/subsidy system. We find that the high-tax scheme works best in inducing the desired level of harvesting, while the tax-subsidy scheme may trigger tacit collusion.

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.

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.

Focuses on the impacts of climate change on reindeer husbandry in the Arctic and local adaptation techniques that could be useful and cooperation for others that need to be developed and shared.

Taking water institutions as an illustrative context, this paper attempts a quantitative analysis of the structural and functional linkages within institutional structure and indicates their performance implications and strategic importance for promoting institutional reforms.
