  • the progress and challenges in sustainable Forestry Development in china
    International Journal of Sustainable Development and World Ecology, 2013
    Co-Authors: Wei Zhao, Guofan Shao, Bernard J Lewis, Dapao Yu, Li Zhou, Wangming Zhou
    Abstract:

    Forestry Development in China has undergone a series of reforms over the past six decades. This article examines temporal changes in forest resources and policies, the current status of Forestry, and future challenges toward sustainable forest management in China. Excessive logging in the 1950s to 1980s badly damaged the nation’s forests, but the adoption of enlightened forest policies in the late 1990s has led to increases in China’s total forest area and growing stock. Forest degradation was ecologically and economically costly, and rehabilitation processes have become increasingly more expensive. The low quality and young age of forest resources, loss of natural forests, and more difficulties in afforestation and reforestation pose severe challenges for China’s sustainable Forestry. It is critically important for China to enhance forest productivity through intensive management, strengthen enforcement, and educational programs for protecting and restoring natural forests, narrow the gap between domesti...

  • roles of digital technology in china s sustainable Forestry Development
    International Journal of Sustainable Development and World Ecology, 2009
    Co-Authors: Lina Tang, Guofan Shao
    Abstract:

    China has the fifth largest forest area in the world and any change in China’s Forestry Development will have inevitable impacts on global ecological sustainability. China has undergone excessive logging of natural forests and also made tremendous efforts in afforestation during the past half century. China’s Forestry is now going through a variety of transitions and several Forestry programs have been implemented to drive Forestry transitions. The goal of these actions is to protect ecological services of forests and sustain China’s Forestry Development. These Forestry programs are spatially sophisticated and cannot be successfully implemented without accurate and transparent forest/Forestry information. A variety of digital technologies, including forest modeling, remote sensing, geographic information systems, global positioning systems, and visualization, have been applied in handling diverse information in China’s Forestry. Digital Forestry is not just a theoretical concept in China. Our digital Forestry experience in northeast China suggests that digital technology is both usable and useful in China’s Forestry Development. Digital technology is playing an important interactive role in China’s top-down Forestry administration system. The analog-todigital transition in technology is expected to lead to the success of Forestry programs and Forestry transitions in China.

  • upland agricultural and Forestry Development in the amazon sustainability criticality and resilience
    Ecological Economics, 1996
    Co-Authors: Emmanuel Adilson S Serrao, Daniel C Nepstad, Robert Walker
    Abstract:

    Abstract This paper provides an overview of agricultural and Forestry Development in the Amazon basin, and presents and discusses the main land use systems in evidence today in that region. These are logging, shifting-cultivation and ranching. The issue of sustainability is addressed, and current Amazonian land use is interpreted in light of ecological impacts and long-run viability. Also considered are the ecological notions of criticality, endangerment, impoverishment and resilience. After addressing the threats of land use encroachment to the forest resource base, the paper identifies sufficient conditions for regional ecosystem sustainability and considers desirable technological and policy-oriented responses in this regard. The paper concludes with a call to future research on land use systems, noting, however, that the greatest challenge is the design of equitable government policy for the adoption of sustainable systems.

  • Small-scale Forestry Development in the Philippines: An investigation of the social and economic factors affecting smallholder Forestry Development
    2009
    Co-Authors: Nicholas F. Emtage
    Abstract:

    Small-scale Forestry in the Philippines Deforestation and poverty are major problems in rural Philippines. Rural Development programs have focussed on community and private Forestry Development as a central means of tackling the problems of poverty and environmental decline yet their outcomes have been erratic. Many programs have failed to account for the variations in the socioeconomic characteristics and attitudes of those in rural communities. This book presents a study of the factors that affect Forestry in the Philippines and results of case studies of households’ socioeconomic circumstances and Forestry Development attitudes in four communities. A typology of households was developed, describing the nature of variations in households both between and within communities. A series of recommendations are made for reforms to improve Development outcomes. The study provide a practical example for Development program administrators and practitioners of how to better understand rural households’ needs and preferences in relation to rural Development programs in the Philippines and elsewhere.

  • an investigation of the social and economic factors affecting the Development of small scale Forestry by rural households in leyte province philippines a typology of rural households in relation to small scale Forestry
    2004
    Co-Authors: Nicholas F. Emtage
    Abstract:

    This thesis investigates the social and economic factors affecting small-scale Forestry Development in Leyte Province, the Philippines, and in particular, the potential to use typologies of rural households to aid the description and interpretation of the diversity of households in relation to Forestry Development. Data for the analysis of the relationships between socioeconomic factors and tree management behaviour and intentions and the construction of a typology of rural households in Leyte was gathered from four case study communities on the Island. Following focus group discussions in each of the participating communities to gather background data and populate the structured interview schedule, representative samples of 50 households were selected and interviewed in each of the four communities. Analysis of the present tree management activities of households in the four communities revealed that most households surveyed (approximately 80%) indicated that they are presently managing at least a few trees, the primary purpose of most tree management activities being to supply timber for the households' own needs. Only 10% of respondents indicated that they intend to sell trees they are presently managing, and 25% stated that they intend to plant and manage trees for the production of timber for sale in the future. Approximately 60% of responding households indicated an interest in developing commercial tree farming on the land they manage. Thus it is concluded that small-scale commercial tree growing is uncommon in the communities involved in the survey, and that many households are interested in developing their tree planting and management activities but feel constrained from participation by various factors. The first level of exploration of the socioeconomic factors affecting rural households' tree management behaviour involved univariate analyses of the relationships between households' tree management behaviour and intentions, their socioeconomic characteristics and their attitudes to Forestry. The level of resources controlled by the household, in terms of the area of the land managed by the household, their tenurial security and their cash income, are correlated with higher levels of participation in Forestry activities, and greater intentions to plant higher numbers of trees in the future. Some farming system variables are also related to higher levels of tree planting and management activity, including the management of livestock and of farm plots distant from their house. While control over higher than average levels of productive resources are, in general, positively correlated to the active management of trees on their land, there are patterns of exceptions to this trend. The exploration of the interrelationships between socioeconomic factors and attitudes affecting households' tree management behaviour was undertaken through the definition of a typology of rural households in relation to Forestry. Five types were defined, each having different attitudes to Forestry activities. The interpretation of the types was undertaken by describing and comparing the socioeconomic and behavioural characteristics of the types in the typology. The types were characterised by differences in their control of productive resources, differences in their present and intended levels and types of Forestry activity, and by differences in their participation in training activities run by Development programs. The characteristics of the types were found to correspond highly with descriptions of the socioeconomic factors affecting Forestry activities of smallholder households reported by previous studies into and theories about the socioeconomic factors affecting smallholder Forestry Development. The typology of rural households does help to describe and interpret the variation within each of the four communities in terms of households' attitudes to Forestry Development and their socioeconomic characteristics. It is concluded that these variations between households mean that the various types of households will be affected in different ways by Forestry Development programs. It is also concluded that the present state of Forestry policies and the market for timber products is such that substantial increase in the level of Forestry activity by smallholders is unlikely without comprehensive land use planning, policy reform in regards to tree registration and transport permits, and market Development. Recommendations for further research and policy Development arising from the thesis focuses on the need to create enabling conditions in which Forestry activities can occur and on ways to address the differing needs of the various types defined in the typology.
