There is a growing assumption that payments for environmental services including carbon sequestration and greenhouse gas emission reduction provide an opportunity for poverty reduction and the enhancement of sustainable development within integrated natural resource management approaches. Yet in experiential terms, community-based natural resource management implementation falls short of expect...
Selective logging is currently a widely adopted management practice throughout the tropics. Monitoring of spatial extent and intensity of such logging is, therefore, becoming an important issue for sustainable management of forest. In spite of successful use of RS in various field of forestry, detection and quantification of selective logging is still a problem. This study explores the possibil...
Forest certification programs provide standards for multiple aspects of forest management, including the use of chemicals for mitigating competition and forest pests. The three most common programs in the United States—the American Tree Farm System, the Forest Stewardship Council, and the Sustainable Forestry Initiative—all address chemical use. To evaluate relative impacts under different cert...
In this article, we introduce China's major forest types and discuss the historical development of forest management in China, including actions taken over the last decade toward achieving SMF. Major challenges are identified, and a strategy for SFM implementation in China is presented. China's forests consist of a wide variety of types with distinctive distributional patterns shaped by complex...
The issue of rapid change in environmental conditions under which ecosystem processes and human interventions will take place in the future is relatively new to forestry, whereas the provision of ecosystem services, e.g., timber or fresh water, is at the very heart of the original concept of forest management. Forest managers have developed ambitious deterministic approaches to provide the serv...
Fo re st ry B rie fin g N um be r 4, M ay 2 00 3 Introduction A major reason for the high failure rate of rural development forestry projects is the weak economic incentives for local forest users and other stakeholders to participate in sustainable forest management (SFM). In view of the high dependency of the rural poor on forests for their livelihoods, this has serious poverty implications. ...
Additions of nutrients, faster growing tree varieties, more intense harvest practices, and a changing climate all have the potential to increase forest production in Sweden, thereby mitigating climate change through carbon sequestration and fossil fuel substitution. However, the effects of management strategies for increased biomass production on soil resources and water quality at landscape sc...
The main purpose of this article is to evaluate different policy options for promoting low-impact logging through the use of economic incentives. To do this we construct a small optimal control theory model within an integrated framework including both the biological and the economic implications of timber extraction. The approach uses detailed stock, yield and cost data from Ghana. A numerical...
For individuals, organizations and nations, success and even survival depend upon making good decisions. Doing so can be extremely difficult when problems are not well structured and situations are complex, as they are for natural resource management. Recent advances in computer technology coupled with the increase in accessibility brought about by the Internet have increased our ability to sol...
Jumla is highly rich in its vast and valuable Non-Timber Forest Products (NTFP) including different kinds of valuable medicinal and aromatic plants. However, in recent years, a significant decrease in availability of commercially traded NTFP species has been experienced. Nevertheless, some important initiatives have also been started to manage NTFPs in a sustainable basis. Community Forestry (C...
