The opportunity for new technologies based on laser radar (or Lidar) to significantly improve forest measurement and contribute to improved forestry operations at similar or lower costs than current methods has been addressed by developing field assessments of current airborne Lidar and a novel CSIRO developed ground based Lidar system. The CSIRO groundbased system is called the ECHIDNA® and it...
Information technology is one of the most important factors that have been impacting the development of forestry construction, with forest farmers playing an increasingly crucialrole in promotion of information technology. Survey data in this paper, collected from Yongan County and Youxi County in Fujian Province, usescombinedRough Set Theory (RST) andSupport Vector Machine (SVM), applied for r...

Smallholder teak (Tectona grandis) plantations have been identified as a potentially valuable component of upland farming systems in northern Laos that can contribute to a “livelihood transition” from subsistence-oriented swidden agriculture to a more commercially-oriented farming system, thereby bringing about a “forest transition” at the landscape scale. In recent years, teak smallholdings ha...
Detailed and realistic tree form generators have numerous applications in ecology and forestry. For example, the varying morphology of trees contributes differently to formation of landscapes, natural habitats of species, and eco-physiological characteristics of the biosphere. Here, we present an algorithm for generating morphological tree "clones" based on the detailed reconstruction of the la...
There is a disjunction between modern international forestry policy and the needs of many people in developing countries. Recent international forest policy has focused on the implications of tropical deforestation for climate change, biodiversity loss and livelihoods. In particular the efficacy of the REDD (Reduced Emissions from Deforestation and Degradation) mechanism has dominated internati...
Over the years, Operational Research (OR) has been used extensively to support the forest products industry and public forestry organizations (e.g., governments, environmental protection groups) in their respective planning activities concerning the flow of wood fiber from the forest to the customer. The applications deal with a wide range of problems, ranging from long-term strategic problems ...
This paper aims to provide a summary review of the evidence on commercial forestry’s ability to reduce poverty. It also tries to identify the key risks associated with greater participation of poor groups in commercial forestry and to identify factors, both internal and external to the forest sector, proven to enable commercial forestry to be pro-poor. It has been prepared for a “scoping” dialo...
