山东半岛城市群城市土地集约利用评价

城市土地集约利用是城市发展的必然要求.结合山东半岛城市群所处的发展阶段和自身特点,从土地投入程度、土地经济产出、土地利用合理程度和土地集约利用发展趋势4个方面建立了城市土地集约利用评价指标体系.运用改进的层次分析法确定各评价指标的权重,采用综合评价法对山东半岛城市群城市土地集约利用进行了评价.根据计算出的城市土地集约利用综合评价值和集约利用分级标准,将山东半岛城市群8个城市分为三类,即集约利用、勉强集约利用和相对粗放利用,评价结果较合理.该评价结果可为山东半岛城市群的城市土地集约利用提供某些科学依据.

Price transmission between products at different stages of manufacturing in forest industries

The theory of demand and supply implies a positive relationship, or “price transmission” between the prices of products at different stages of manufacturing. This relationship was investigated with quarterly prices of softwood stumpage in the US South, and national prices of forest products, from 1977 to 2002. All prices, net of inflation, were found to be nonstationary and there was no evidence of co-integration between prices. Vector autogressive models, augmented by Granger causality tests and multiplier analysis showed that there was a one-to-one permanent positive response of the southern sawtimber stumpage price to a permanent change in the national lumber price. There was also a one-third permanent positive response of the national paper price to a permanent change in the national pulp price. There was no relation between regional pulpwood prices and national pulp or paper prices. When price transmission was significant, the full adjustment took about 2 years.     

In Vino ‘No’ Veritas: impacts of fraud on wine imports in China

China is one of the largest wine importing countries in the world and is poised for continued import growth in the future. Increased wine purchases throughout China have given rise to persistent fraud where fake wines are packaged and sold with counterfeit contents and labels. For exporting countries like France, counterfeit wines displace market share, damage foreign brand reputation, and cause distrust in consumers who are aware of counterfeiting problems throughout the country. We examine the impact of fraudulent wine events (as measured by negative media reports) on Chinese wine demand differentiated by supplying country. We employ the Rotterdam demand system and a switching regression procedure to estimate import demand and compare results across different media variable specifications. Results consistently show that negative reports disproportionately affect French wine regardless of how the media variable is specified. This is not surprising because most fraudulent events involve French wine counterfeits.     

Underpayment of Small Producers of Coffee and Cocoa in Sierra Leone

Fieldwork shows that many Sierra Leonean producers do not receive the official producer price for their coffee and cocoa, due to the concentration of buying stations, credit relations, the small quantities offered for sale, and the lack of marketing knowledge of the numerous and unorganized farmers. To the traders underpayment may seem economically justifiable to a certain extent, but to the farmers it means poverty and debt. A new village marketing centre project aims at remedying this situation and has already led to higher prices. Although no longer allowed to take their "just" share from the producers, traders are still willing to deal with the new centres.     

EU Policies on Bioenergy and their Potential Clash with the WTO

The paper outlines EU policy on bioenergy, including biofuels, in the context of its policy initiatives to promote renewable energy to combat greenhouse gas emissions and climate change. The EU’s Member States are responsible for implementing EU policy: thus, the UK’s Renewables Obligation on electricity suppliers and its Renewable Transport Fuel Obligation and road‐fuel tax rebates are examined. It is unlikely that EU policy is in conflict with the WTO Agreement on Agriculture or that on Subsidies and Countervailing Measures, but its provisions on environmental sustainability criteria could be problematic.     

Adoption des Politiques de Protection de l'Environnement et performance des Entreprises Camerounaises

The objective of this paper is to evaluate the effect of the environmental protection policies of by Cameroonian firms on their performance. It uses the endogenous switching regression technique and propensity scores applied to micro-data from 639 firms in Cameroon. The results show that only 17% of firms adopt these measures, while on average 85% of firms produce solid, gaseous or liquid waste. The results also indicate that the adoption of these environmental protection policies increases operating costs while significantly improving the turnover and the performance of the productive capacity of the company. These increases are 39.11%, 58.6%, and 38.63% for operating costs, turnover and return on productive capacity of the company, respectively. However, firms can also suffer significant losses resulting from the non-adoption of environmental policies. In fact, firms that do not adopt environmental protection policies have their performance reduced by an average of 1.625 percentage points.     

Options for African agriculture in an era of high food and energy prices

In a world of high food and energy prices, Africa has an imperative to do a better job feeding itself and ensuring that its people are food secure. At the same time, there is a new business opportunity to work with the private sector in developing the continent's potential to produce significantly more food, raw materials, and biofuels for regional and world markets. A challenge for African policy makers is to find the right balance between a food security and a business agenda, and to ensure that the business agenda engages with large numbers of small farms. Agricultural development requires many things, but the fundamentals for Africa are developing markets, increasing agricultural productivity, and managing volatility. This cannot happen at sufficient scale and speed without strong public sector leadership, enabling policies and investments, and well‐focused implementation strategies.

Eviction policy in postwar Angola

Angola's four decades of civil war continue to have a profound effect on the country's recovery and development. While the end to the war in 2002 and the subsequent extraction of natural resources has fueled the country's economic recovery for a minority, for the majority recovery depends less on natural resource extraction than it does on acquiring and maintaining secure access to land and property upon which viable livelihoods can be rebuilt. However the current large scale evictions in urban and peri-urban areas of the country and the resulting acute tenure insecurity is significantly worrying, and is the single most acute land rights, land policy, and political problem in the country. Aspects of the country's constitution and the development of the postwar land law facilitate eviction, and an important opportunity to upgrade postwar informal land rights has been missed. Land and property rights problems have played a significant role in the country's armed conflicts and social problems, and current trends are constructing a difficult future.     

CARBAP and innovation on the plantain banana in Western and Central Africa

Plantain is considered as a major staple food in Central and Western Africa with a production estimated at approximately 8 million tons (Lescot, 2007). But almost all small producers do not have access yet or do not use the innovations from research, and yields are thus very low. CARBAP (African Research Centre on Banana and Plantain) is a novel example of a regional research partnership for plantains and bananas across Western and Central Africa and particularly Cameroon, Democratic Republic of Congo, Côte d'Ivoire, Ghana, Guinea and Nigeria. It links researchers, creates novel platforms, undertakes training and disseminates materials. It encourages mass propagation by farmers—after training, some 10 million new disease-resistant plants were spread to farms over two years.
