While recently developed standards of good practice in conservation are helpful, a framework for evaluation is needed that supports systematic analysis of conservation effectiveness. A conceptual framework and scorecard developed by the Cambridge Conservation Forum help to address common constraints to evaluating conservation success: unclear objectives, ineffective information management, the long time frames of conservation outcomes, scarcity of resources for evaluation, and lack of incentives for such evaluation.Resource Type: Journal Papers
This paper reviews the potential for multiple benefits that might be attained by reducing emissions from deforestation (RED) through a mechanism developed under the UNFCCC. These benefits are relevant to national commitments under several environmental and sustainable development conventions and instruments, and may not be directly correlated with reduced carbon emissions. The design of the mechanism and its implementation will affect the degree to which these other benefits, such as biodiversity conservation, livelihoods, watershed protection and other ecosystem goods and services, are obtained.Resource Type: Reports
Consideration of predictions for global climate change and the general scientific principles underlying the interaction between vegetation and climate, and examination of likely scenarios for different forest regions.Resource Type: Reports
The conservation of world forests is an important measure in order to address the ever-worsening consequences of climate change. Tanzania has over 34 million hectares of forests and woodland habitats (more than 30% of the whole country). This report concludes that REDD strategies in Tanzania should be integrated with, and improve upon, current conservation strategies.Resource Type: Reports
Swietenia macrophylla King (Meliaceae: Swietenioideae) provides one of the premier timbers of the world. The mahogany shoot borer Hypsipyla robusta Moore (Lepidoptera: Pyralidae) is an economically important pest of S. macrophylla throughout Asia, Africa and the Pacific. No viable method of controlling this pest is known. Previous observations have suggested that the presence of overhead shade may reduce attack by H. robusta, but this has not been investigated experimentally. This research was therefore designed to assess the influence of light availability on shoot-borer attack on S. macrophylla, by establishing seedlings under three different artificial shade regimes, then using these seedlings to test oviposition preference of adult moths, neonate larval survival and growth and development of shoot borer larvae.
The results indicate that shading of mahogany seedlings may reduce the incidence of shoot borer attack, by influencing both oviposition and larval development. The establishment of mahogany under suitable shade regimes may therefore provide a basis for controlling shoot borer attack using silvicultural approaches.Resource Type: Journal Papers
Using global scale maps and statistics, we estimate that the conversion of all vulnerable tropical forests to the most valuable other land use at each location could lead to emissions of 670 Gt carbon dioxide (CO2). We then evaluate the role of the global protected area network in preventing emissions from tropical deforestation.Resource Type: Reports
Biodiversity Loss and Conservation in Fragmented Forest Landscapes is the product of over 10 years of intensive field research into the changing montane and temperate rainforests of Mexico and South America. By concentrating on these largely overlooked environments, the studies reported allow for comparative analysis across areas and help identify how human disturbance has impacted the biodiversity of all forest types. Chapters incorporate features of landscape ecology, floristic biodiversity, conservation and policy and vary from in-depth investigations of a single study area to integrated examinations across regions.Resource Type: Reports
The paper provides an analysis of the ecosystem-derived multiple benefits of REDD+.
The terminology around multiple benefits is not yet clear cut. Here, the different terms in use are reviewed and suggestions are made about how terms can be used in a consistent way.Resource Type: Reports
Agricultural lands are essential for providing food and forage for maintaining a healthy environment. Growing human populations are placing increasing demands for new lands for agricultural production. At the same time, there is a need to maintain or increase our forest cover for biodiversity and carbon sequestration. Unfortunately, our land base is limited. Consequently, there is strong competition between those lands will be used for forestry and those that will be used for agriculture. Current assessments of agriculture and forested lands are often carried out by separate entities. Often, there is duplication of data collection, information gaps, etc. The bottom line is that we do not really know how much land currently serves the needs of agriculture and forestry, which lands are best suited for conversion to alternate use, and where they are located. In order for decision makers to make more informed decisions, we need complete and up-to-date geo-referenced inventories. The purpose of this paper is to discuss the problems of separate resource inventories and to present ways to overcome these problems by integrated assessments.Resource Type: Journal Papers
Reports of rapid growth in nature-based tourism and recreation add significant weight to the economic case for biodiversity conservation but seem to contradict widely voiced concerns that people are becoming increasingly isolated from nature. This apparent paradox has been highlighted by a recent study showing that on a per capita basis, visits to natural areas in the United States and Japan have declined over the last two decades. These results have been cited as evidence of "a fundamental and pervasive shift away from nature-based recreation"-but how widespread is this phenomenon? We address this question by looking at temporal trends in visitor numbers at 280 protected areas (PAs) from 20 countries.Resource Type: Journal Papers
