Overview and Forecast on Forestry Productions Worldwide

Our world is largely dependent upon the forestry productions. Through the exploitation of forest reserves, we manufacture various industrial products, furniture, and obtain fuel and energy. Forestry productions should be conducted without large-scale deforestation and environmental degradation. In present study we perform a review and forecast analysis on forestry productions worldwide, with the objectives of providing an insight into the trend for several types of forestry productions in the future, and providing referential data for sustainable forestry productions and environmental management. Polynomial functions are used to fit trajectories of forestry productions since 1961 and forecasts during the coming 20 years are given in detail. If the past pattern continues, world fibreboard production would dramatically grow and reach 224,300,000 ± 44,400,000 m³ by the year 2020, an increase up to 240.7 to 408.9% as compared to the present level. Roundwood production of the world would change by −55.5 to 70.4% and reach 3,526,600,000 ± 2,066,800,000 m³ by 2020. In 2020 world production of sawlogs and veneer logs would change by −100 to 164.6% and reach 1,212,900,000 ± 1,242,600,000 m³. Global wood fuel production would change by −68.9 to 1.4% and reach 1,130,900,000 ± 600,800,000 m³ by 2020. Forestry productions in developed countries would largely surpass productions in developing countries in the near future. World forestry production grew since 1961 excluding wood fuel. Roundwood and wood fuel account for the critical proportions in the forestry productions. Wood fuel production has being declined and rapid growing of roundwood production has slowed in recent years. Widespread use of regenerative wood substitutes and worldwide afforestation against deforestation will be among the most effective ways to reduce deforestation and environment degradation associated with forestry productions.     

A forecast analysis on fertilizers consumption worldwide

This study aimed to make a review and forecast on fertilizers consumption worldwide in order to provide basal data for the decision-making of fertilizers production and for the environmental impact assessment of fertilizers application. It was found that fertilizers consumption was dependent on human population and the increase of fertilizers consumption was mainly resulted from expansion of human population. The univariate linear model, y=a+rx(t), where y is the fertilizers consumption, x(t) is the total human population at year t, r is the annual fertilizers consumption per capita, was used to fit historical data of fertilizers consumption, and the forecasts during 2010 to 2030 were given in detail. Model analysis showed that world’s per capita annual consumption of total fertilizers, nitrogenous fertilizers, phosphate fertilizers, and potash fertilizers, were 34.6, 24.4, 6.6, and 3.7 kg, respectively. Per capita annual consumption of total fertilizers for Asia, Africa, Caribbean, Oceania, North & Central America, Europe, and South America were 38.8, 5.9, 6.8, 114.0, 62.9, −0.9, and 43.6 kg, respectively. Compared to the current level, the world’s total fertilizers consumption would reach 226,150,381 Mt by 2030, an increase of 32.1% against current level. Worldwide consumption of nitrogenous fertilizers, phosphate fertilizers, and potash fertilizers would reach 141,800,601, 50,961,129, and 33,388,650 Mt by 2030, increasing 37.5, 25.8, and 21.2% based on current levels. Consumption of total, nitrogenous, phosphate, and potash fertilizers in Asia and Africa would increase 54 to 55% and 40 to 60% by 2030, respectively. Total fertilizers consumption in North & Central America would see an increase of 39.4% by 2030, and in South America and Oceania it would increase by 30.9 and 64.7%, respectively. By 2030, Caribbean’s consumption for total fertilizers would increase 2.8%. Europe’s total fertilizers consumption was forecast to continuously decline and would have a decrease of 2.4% by 2030. Annual relative growths of consumption of total fertilizers, nitrogenous fertilizers, phosphate fertilizers, and potash fertilizers for the world, Africa, Asia, and South America were forecast to decrease in the forecast period. For North & Central America, annual relative growths of consumption of total fertilizers and nitrogenous fertilizers would decrease and the others would increase annually by 2030. Annual relative growths of consumption of total fertilizers, phosphate fertilizers, and potash fertilizers for Oceania were forecast to rise annually by 2030. Europe’s annual relative growths of consumption of total fertilizers and potash fertilizers would decrease in the future.     

Practical and ethical considerations of agricultural research assistance for the Third World

The right to eat and to an adequate standard of living for everyone motivates agricultural research assistance to developing countries with the primary objective of assuring sufficient food supply. This article focuses on aspects of food production and related agricultural research with specific examples from animal production. It discusses ethics of agricultural research in light of the utilitarian theory and compares livestock production in developing and developed countries. Major reasons for low outputs of animal production in developing countries are identified, and the potential for increasing the productivity of original, extensive production systems is evaluated. The article reviews the current status of biotechnology in developing countries and discusses several advanced animal technologies. The conclusions emphasize the need to involve local professionals in all phases of research and technology transfer in developing countries, avoidance of research that may worsen the situation of the recipients, sustainability of production systems, and the need for detailed assessment of potential impacts of technology on recipients.     

沈阳市利用国家开发银行贷款推动环保产业发展浅析

沈阳市政府从2005年开始到2007年11月末，通过沈阳恒信国有资产经营有限公司融资平台从国家开发银行融入贷款资金近295．17亿元用于老工业基地改造。据统计，共有139亿元开发银行贷款用于沈阳市“沈阳西部污水治理工程（西部细河改造）”等环保工程、环境治理等项目，占全市开行贷款总数的47％。项目的实施改善了我市的生产和生活环境，对提高沈阳市的城市品位，完善城市功能起到了积极的促进作用。但由于部分项目前期准备工作不充分、管理主体缺位、二级平台不健全、配套资金筹措不及时等原因，影响了项目进展和资金有效使用，为提高沈阳政府融资信誉，有关部门应通过建立我市开行贷款项目的储备制度、加强二级平台建设、多渠道筹集配套资金、建立有效的防范债务风险的机制等项措施，努力防范和化解财政风险。     

Invisible Losses and the Logics of Resettlement Compensation

The necessity of compensating people negatively affected by conservation and other development projects has been widely acknowledged. It is less widely acknowledged that because conventional compensation assessments focus on material resources and their economic equivalents, many important losses incurred by resettlers are invisible to project authorities. Through ethnographic observations and interviews, we documented losses identified by people facing resettlement from Mozambique's Limpopo National Park. We also examined resettlement planning documents to determine why decision makers’ assessments of natural resource use and value neglect losses residents identified as critical. Identifying, preventing, and mitigating invisible losses in resettlement planning necessitates a better understanding of intangible benefits residents derive from resources, which are often as or more important than their readily apparent material properties. These benefits include but are not limited to decision‐making authority linked to owning land versus having the use of fields; ancestral identity and social belonging linked to gravesites; the importance of tree roots that provide a powerful sense of security because they suppress hunger in periods of scarcity; and the importance of people's location within social networks and hierarchies as they determine the benefits versus risks that will be incurred through resettlement.

Quoting “the Environment”: Touchstones on Earth

Media influence public awareness through agenda setting and framing of news by selecting what is published, how frequently and through what frames. This content analysis compares portrayals of climate change based on political ideology of the media. It examines daily coverage of climate change in Santiago, Chile by the conservative, El Mercurio, newspaper, and the liberal, La Nación. Twenty percent of the 1,628 articles published in 2003, 2005, and 2007 which included the words “cambio climático” (climate change) or “calentamiento global” (global warming) were analyzed for frequency, content, images, and frames. The liberal newspaper published twice as many articles that were twice as long, with four times as many illustrations about climate change. They presented more thematic and diverse frames than the conservative newspaper. Government sources and conflict frames dominated both newspapers, reflecting some similar maturation processes of climate change coverage found in Europe, the United States, and elsewhere.     

Muting the Voice of the Local in the Age of the Global: How Communication Practices Compromised Public Participation in India's Allain Dunhangan Environmental Impact Assessment

Public participation is widely lauded as a way to make environmental decisions more democratic, to improve their quality, and to enhance their legitimacy. Scholars and citizens around the world repeatedly complain, however, that public participation frequently serves primarily as a pro forma exercise to defend predetermined decisions rather than as a meaningful opportunity for the affected public to influence decision-making. These critiques persist despite considerable research suggesting ways to improve the quality of public participation. This essay explores this problem by analyzing citizen involvement in the environmental impact assessment (EIA) processes for the Allain Duhangan hydropower project in northern India. It describes how meaningful public involvement was compromised—despite repeated objections by citizens and independent consultants—by four communication practices: (1) failing to provide adequate access to information; (2) predetermining EIA outcomes by controlling the definition of issues (“definitional hegemony”); (3) privileging scientific/technical discourse; (4) utilizing “consultative” forms of communication that promote one-way flows of information rather than more interactive forms that encourage the joint construction of information and values. This study further argues that these practices persist because they serve as acts of power that privilege dominant actors and interests in the larger socio-political context. This analysis thus suggests that altering communication practices that compromise the quality of public participation may require attending to the interaction between communication practices, relations of power, and the larger socio-political context in which public participation takes place.
