Small local hunting communities in Siberia are very distant from any governmental control. Hunted waterbird species, including globally and regionally threatened species, rely for their well-being on the self regulation of remote hunting communities. Interviewed hunters showed a profound knowledge of Baikal Teal, its population status, and the causes of their past decline. Whether the knowledge is shared by other communities in the region and beyond in Northern Siberia needs verification.
The importance of non-timber forest products (NTFPs) to rural income was examined in a highland community in the Sierra de Manantlán Biosphere Reserve, Jalisco-Colima, Mexico. Rapid Rural Appraisal (RRA) techniques were used to interview 70 of households in the community of El Terrero. Of the nine plant species identified as NTFP sources, the two principal species traded by the community were tila (derived from the flowers and fruits of the tree Ternstroemia lineata), and blackberry (Rubus spp.). Collecting and selling of NTFPs was almost exclusively undertaken by women, with 80 of respondents participating. NTFP sale ranked as the most important source of cash income for 30 of women interviewed, and either second- or third-most important for the remainder. The research examined harvesting impact on populations of T. lineata, an understory tree species characteristic of cloud forest, which this was assessed in the four most-frequented collecting sites. Our results suggested that current harvesting approaches appear to be sustainable, although 95 of the women interviewed reported a decline in resource availability within the last 15 years, apparently resulting from illegal cutting. Suggestions are made with respect to the sustainable development of NTFP resources to help alleviate poverty within the Reserve.Resource Type: Journal Papers
Assessments of forest biodiversity - the diversity within forest species, between species and of forest ecosystems - are essential if forest resources are to be effectively conserved and sustainably managed (Hunter, 1999). Assessments are needed to provide information necessary to support biodiversity-related decision-making in forest policy and management. However, assessment of forest biodiversity presents a number of challenges. First, because of the complexity of biodiversity, information about it needs to be assembled and expressed based on simplified variables, typically in the form of indicators (Noss, 1990, 1999). Second, since decisions relating to forests are made at a variety of scales, biodiversity data and indicators need to be aggregated across different scales for monitoring and reporting purposes (Noss, 1990; Turner, 1995).Resource Type: Journal Papers
Commercialization of non-timber forest products (NTFPs) has been widely promoted as a means of sustainably developing tropical forest resources, in a way that promotes forest conservation while supporting rural livelihoods. However, in practice, NTFP commercialization has often failed to deliver the expected benefits. Progress in analyzing the causes of such failure has been hindered by the lack of a suitable framework for the analysis of NTFP case studies, and by the lack of predictive theory.
We address these needs by developing a probabilistic model based on a livelihood framework, enabling the impact of NTFP commercialization on livelihoods to be predicted.Resource Type: Journal Papers
At the 9th meeting of the SBSTTA of the CBD a recommendation was made to begin testing of five biodiversity indicators in order to measure progress towards the 2010 target. This paper considers one of these indicators for Pan-Europe. The basic principle of the index is to calculate the average trend in abundance of a set of ecosystem-representative species. The index is considered to be generic, i.e. applicable to all ecosystem types including forests. It can produce both headline messages for high-level policy and communication, and detailed information for in-depth analysis. This paper describes the conceptual framework of the index and explores the data availability for the index in Pan-Europe.Resource Type: Journal Papers
This study demonstrates the utility of carbon isotope discrimination in describing genetic adaptation to arid environments, although it is probably most useful in detecting differentiation when the strategy of the species under investigation is to increase water use efficiency, rather than drought-avoidance. The results suggest that populations on the eastern and western sides of the Andes should be treated as separate management units for the purposes of conserving the genetic resource of this species.Resource Type: Journal Papers
This review focuses on woody bamboos with the highest diversity recorded in the Asia-Pacific region where bamboos play a major role in ecosystem dynamics in many forests.
The genetic diversity of the remaining forest bamboos, of which many are highly susceptible to deforestation, is of great concern and an accurate information base is required as a foundation for policy and management decisions affecting bamboo. A programme to strengthen the Red List assessments of bamboo species status is also needed, one that prioritizes the assessment of species with the smallest estimated geographical ranges and least remaining habitat.Resource Type: Journal Papers
Entrepreneurship and innovation by actors in the market for non-timber forest products (NTFPs) cannot be fully understood without a proper understanding of the position and behaviour of actors in the value chain of NTFPs. This paper places the market for NTFPs in the emerging literature on value chains which has, so far, lacked a detailed analysis of NTFPs. Our analysis reveals that certain key entrepreneurs are a driving force of success throughout several NTFP value chains in both Bolivia and Mexico. Where market information is scarce, e.g. where producers are distant from consumers, key entrepreneurs often govern entire value chains.
Rather than criticising the monopolistic position of individuals, it is important to understand how the activity of key entrepreneurs can be supported in spreading successful commercialisation further and where necessary control negative impacts of their role. Our analysis indicates that policies to support commercialisation of the case study NTFPs would also need to be tailored to each value chain.Resource Type: Journal Papers
The CBD target "to achieve by 2010 a significant reduction of the current rate of biodiversity loss" was incorporated into the Millennium Development Goals in 2002. Our lack of progress toward the 2010 target could undermine achievement of the MDGs and poverty reduction in the long term. With increasing global challenges, such as population growth, climate change, and overconsumption of ecosystem services, we need further integration of the poverty alleviation and biodiversity conservation agendas.
Since about 1600, 486 animal species have been recorded extinct. This represents about 0.04 of all animal species so far described. In the same period, 600 plant species are known to have disappeared, about 0.25 of the total. These figures are much smaller than those of the Permian/Triassic and Cretaceous/Tertiary mass extinctions. One might therefore conclude that at present life on earth is at comparatively little risk of extinction. However, there is a growing body of data to show that the converse is true.Resource Type: Journal Papers
