Book (stand-alone)Forest change in the Greater Mekong Subregion (GMS) 2017
Also available in:
No results found.This report looks at both negative and positive drivers that affect forest change in the Greater Mekong Sub-region (GMS) in the last 25 years (1990-2015) in order to have a better understanding of their influence on forests in the region. It evaluates policies and measures in relation to drivers of forest change. Agricultural expansion, infrastructure development particularly hydropower dams and road construction, logging, mining operations and forest fires are the most dominant drivers of fores t loss in GMS. At a positive note, almost all countries in the region have adopted policies that support SFM and balance the social, economic and environmental aspects of forestry. Furthermore, there seems to be a movement towards sustainable policies which influence the shift towards SFM, forest conservation and afforestation and reforestation. Although it seems the policies addressing the drivers of deforestation exist at local, national and international level, their effectiveness has been mi xed. T his report presents forest changes in the Greater Mekong Subregion (GMS) over a period of 25 years between 1990 and 2015. It describes key drivers that have affected these changes. Some drivers influenced forests negatively in that they resulted in deforestation and forest degradation. On the other hand, positive drivers promoted sustainable forest management (SFM), afforestation and reforestation and forest conservation. -
ArticlePredicted climate change impact on natural teak forests in the Greater Mekong sub-region
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Teak (Tectona grandis) is one of the most valuable hardwood species. Natural teak forests, largely distributed in South Asia and Southeast Asia, but they are in danger because of over-exploitation, non-sustainable management, encroachment, and potentially the long-term effect of climate change. The objectives of this research are to predict the presence and future geographical range of natural teak forests in the Greater Mekong Sub-region, and to determine the effectiveness of protected areas for in-situ conservation. Geo-referenced species occurrences of natural teak across the Mekong region were gathered from previous studies and ongoing ITTO Teak Project in Mekong. In addition, potential environmental requirement variables were developed or gathered from various sources. Maximum Entropy (MaxEnt Model), a present-only spatial distribution model was employed to generate present and predicted species range in 2050 under the CMIP6 scenarios. The results of species distribution models show that the suitable habitats of native teak are likely stable by 2050 as the result of wide climatic tolerance range. However, its distribution in southern Myanmar and northeast Lao PDR would loss climatic suitable habitats, whereas semievergreen forests in northern Myanmar are becoming more suitable by all scenarios.

Book (stand-alone)Understanding the impact of planted forest on smallholder livestock farmers and their livelihoods in the Greater Mekong Subregion 2021
Also available in:
No results found.Significant forest change in the Greater Mekong Subregion (GMS) has resulted in deforestation of primary forests and expansion of plantation forests. Although plantation forest development benefits rural communities through income generation and employment opportunities, there have been negative impacts, including reductions in livestock grazing land and collection of non-timber forest products. This study analysed the association between primary forests, plantation forests, grazing areas and large ruminant populations in Cambodia, Lao PDR and Viet Nam. The report showed that livestock populations in the GMS are dynamic and have been under pressure due to enhanced trade and demand in red meat in China and Viet Nam, with a generally positive association between planted forest areas and populations of cattle and buffalo in Lao PDR and Viet Nam indicated. Tree plantations were an important source of income and generally perceived as having a positive impact on rural livelihoods, despite negatively impacts in grazing land availability. It is recommended that integrative approaches that include the collection of household level data to assess the impact on smallholder livelihoods and the collection of regional level data to capture forest changes in future forest assessments, enabling a more comprehensive understanding of the association between primary forests and planted forest on smallholder livestock production. Silvopastoral models have the potential to provide more viable and sustainable alternatives to the current forestry and livestock production models, supporting the transformation to more sustainable agriculture for better production, better environment, and sustainable development goals in GMS countries and beyond.
