This paper analyzed the existing conditions and tendency in forest ecological restoration of the province and revealed the confronting problems in ecology and economy. The authors divided Jilin Province into three ecological economic zones, including nid-west farming and stockbreeding area, east hilly diversified-operation area, and Changbai Mountain national forest area, and discussed the direction and tasks of forest ecological restoration of each zone. Some Countermeasures and suggestions were put forward for restoration of forest ecology of the province.展开更多
From the concept of urban forest and status quo of urban forest in Nanchang,the problems existing on urban forest were proposed,as well as countermeasures and suggestions.

From the understanding of discourse as a social practice, this paper is based on the analysis of 265 parliamentary pronouncements, 19 numbers of an institutional magazine, and 626 news texts from the most important local newspaper, all published between 2007 and 2010. It reveals a shift in the discourse about the ZFM, guided by ecological modernization. The industries are now presented as responsible for preserving the rainforest： it is said that if the tax incentives stop, there will be unemployment and deforestation. This tragic story line does not recognize the role of traditional peoples and communities in forest conservation and neither is open to the public debate about other models of development for the Amazon.展开更多

It may be further stimulated by the Clean Development Mechanism for carbon sequestration. However, there is an intensive and on-going debate about the adverse effects arising from afforestation in dryland areas, such as soil drying up which may cause further damage to the success of forest restoration, and the water yield reduction from watershed which may harm the regional development. On other hand, some preliminary studies showed a possibility that these adverse effects may be diminished more or less by properly designing the system structure and spatial distribution of forest/vegetation in a watershed. However, it is urgent to develop an evidence-based and sustainable new forestry policy for harmonizing forest-water interrelation. As a leading country in afforestation, China is beginning to develop a more trans-disciplinary and cross-sectoral forestry policy for harmonizing forestry development with water management. The main points of the changing new forestry policy should include： （1） Establishing a regional development strategy focusing on harmonized forest-water relations; （2） Taking forest-water interactions as an important part of evaluation; （3） Reducing the ＇eco-water＇ quota of forests through technical advancement; （4） Developing and extending water-adaptive forest management practices; （S） Strengthening forest ecohydrological research and decision support ability.展开更多

A hierarchical method of policy and legislation review and analysis was devised for this study. Findings indicated that most national policies and legislation are outdated and old-fashioned, with gaps and overlaps, and there is lack of collaboration between institutions implementing these. The present national forest policy does not adequately guide the development of NTFPs. As a consequence, whilst international policies and legislation capture an excellent spectrum of elements and issues on NTFPs they still remain difficult to implement. However, national level criteria and indicators have issues and elements that are relevant to the sustainable use of NTFPs. It was recommended that national strategies, action plans, policies and legislation be reviewed and updated. The study shows that there are no existing institutional networks or formal collaboration between the institutions involved in the implementation of local, national, regional, and international policies and legislation that affect NTFPs. Government, private sector, Non-Governmental Organizations （NGO＇s）, communities, individuals, and all concerned agencies should jointly develop and implement policies and legislation to provide secure access and benefits to people whose livelihood depends on/is supplemented by NTFPs and further foster networking and collaboration. The immediate adoption and implementation of the 11 policy recommendations on the sustainable management of Non-timber Forest Resources compiled by the Secretariat of the Convention on Biodiversity （CBD） from the Convention on Biological Diversity is highly recommended. It is worthwhile to note that while some of the 11 recommendations were directly inherited from certain articles of the CBD some are general recommendations.展开更多

This research analyzes the effects of EU biomass imports from the Southeast U.S. on Southeast U.S. timber prices, inventories and production and on EU imports of feedstock. The SRTS （sub-regional timber supply model） was used to simulate market responses to changes in woody biomass consumption in the U.S. and the EU between 2008 and 2038. Results indicate that the price of imported wood pellets in the EU is sensitive to future U.S. renewable energy policies, the developments of which are so far uncertain. The analysis indicates that with bioenergy demands, prices increase for U.S. softwood roundwood from 25% to 125% by 2038 depending largely on U.S. domestic policy. Demand increases led to supply responses and increased carbon storage in Southeastern U.S. over time.展开更多

The major objective is to ascertain the forest dependent survival strategies of rural women in Aniocha South Local Government Area of Delta State. The specific objectives are to ascertain the socio- economic characteristics of the women, find out the forest based activities of the women, identify what they do with products collected from the forest, establish how much income they make from such products weekly and identify the challenges of these women in exploiting forest for survival. Ten villages were selected and from the selected communities, 15 women were randomly selected in each community to give 150 respondents. From the result of the survey about 96.0% of the respondents had household sizes of between 6-10 persons. Women collect many forest products which include seeds, herbs, honey, mushroom, fuel wood, snails, stimulants, bitter kola, pear, raffia leaves （fronds）, edible worms, wrapping leaves, spices, bush mango, locust beans, wild fruits, leaves, fuel wood, snails, mushrooms and fruits. Some of the forest products are used for income generation only, some for household use, while others are used for both income generation and household use. The major constraint is the decline in the availability of forest products as a result of deforestation, over exploitation, bush burning and long distance to available forests. The study shows that forest products play a significant role in improving the livelihood of rural people. Rural development and future forest conservation strategies and interventions should pay attention to the contribution of forest products to people＇s livelihood and environmental sustainability.展开更多
