| The report examines the relationships between agricultural policies in the North China Plain, the approaches to water management that evolved from them, the quantity of water that was actually used, and the consequent groundwater depletion beneath Luancheng County, Hebei Province, from 1949 to 2000. To systematically address these relationships, we use a comprehensive water-balance approach. Our results indicate that a single, longstanding policy-that of using groundwater to meet the crop-water requirements not supplied by precipitation-is responsible for the steady rate of groundwater decline. |

| The importance of bio-fuels as an alternative to oil is growing due to the increasing volatility of oil prices. As bio-fuels increasingly replace oil, their higher demand can be an opportunity for developing underdeveloped countries rich with resources for bio-fuel production to engage in such production and as a result, develop. The feasibility of growing the relevant feedstock, Jatropha curcas, in this case, for the production of bio-fuels, specifically, bio-diesel, in Tanzania is evaluated. The factors, which are investigated, include policy, population density, technology and infrastructure. It was found that the labour characteristics, population density and the state of the available technology provide suitable conditions for bio-fuel production.... |

| Agriculture, an ecosystem transformed by humans for the purpose of supplying food, fiber and biofuel, can provide people a host of benefits, or ecosystem services (ES). While markets exist for farm products, many of today’s central agro-environmental policy concerns are related to ES that lack complete markets, such as regulating ES and recreational, aesthetic and cultural ES. Valuation of non-marketed ES linked to agriculture is needed to improve their utilization and efficient provision. Some ES that facilitate agricultural production or provide natural amenities can be perceived by people through various natural resources and landscapes on farmlands and surrounding areas. One indirect way to measure the value of ES is via what people pay for the lands... |

| The paper provides a methodology that is feasibly implemented for integrated environmental-economic (or 'green') GDP accounting and productivity measurement. The shadow prices for environmental inputs, which enable us to calculate green GDP and to design a pollution tax scheme and tradable permit system for social optimum, can be derived. The development of the statistics of green GDP and green productivity growth provides a fundamental component of policy-making for socially optimal growth and of formulating the market mechanisms for environmental management. |

| One approach to internalising a negative externality of economic activity is to impose a Pigouvian tax equal to the marginal cost of the externality. However, this approach overlooks the possibility that the tax revenue can be earmarked to correct the externality directly, i.e. financing the environmental protection projects. It is found that a pure Pigouvian tax is usually not an optimal policy. This issue is examined in both partial and general equilibrium, static and dynamic settings. Certain conditions for justifying a pure Pigouvian tax or a fully earmarked tax scheme are developed. |

| This paper aims to examine the potential of the Clean Development Mechanism (CDM) to address energy- related issues during the rural transition process in China, using a case study of quickly urbanizing and industrializing Yinzhou district in coastal Zhejiang province. Yinzhou's per capita GDP reached US$ 3100 in 2002, three times China's average, and is targeted to achieve $10,000 in 2020. We assess the current energy status of Yinzhou, and provide projections of energy consumption and CO2 emissions up to the year 2020. Energy resource shortages and limited possibilities to obtain coal-fired electricity from national grid illustrate the opening gap between energy supply and demand. We find that Yinzhou's CDM potential is concentrated in efficiency... |

| Despite the growing concern about actual on-going climate change, there is little consensus about the scale and timing of actions needed to stabilise the concentrations of greenhouse gases. Many countries are unwilling to implement effective mitigation strategies, at least in the short-term, and no agreement on an ambitious global stabilisation target has yet been reached. It is thus likely that some, if not all countries, will delay the adoption of effective climate policies. This delay will affect the cost of future policy measures that will be required to abate an even larger amount of emissions. What additional economic cost of mitigation measures will this delay imply? At the same time, the uncertainty surrounding the global stabilisation target to be... |
