Vietnam Acacia hybrid was selected by Acacia mangium across A. auriculiformis. Five clones was introduced from Vietnam by exchange forest seeds. Four test plantation was built in South China including Jiangmen(JM), Hepu(HP), Zhangzhou(ZZ) and Chuxiong(CX). Acacia hybrid could grow, flower and fruit at the four sites and productivity were all higher than CK after two years. Five hybrid Acacia clones were all higher than CK on high growth character, and were ranked as ZZuff1eJMuff1eHPuff1eCX. The height of clone No. 73 was 5.2m and more 24% than CK. There were significant difference on diameter of breast height(DBH) between clones and CK at the four sites. Clones DBH were all bigger than CK and ranked as HPuff1eZZ=JMuff1eCX. The DBH of clone No. 73 was 5.0cm and more 35% than CK. The individual volume of clone No. 73 was 0.0042m3 at HP site. The wind-fall rate of Acacia hybrid clones were 35% , CK was 67% after typhoon Rammasun 2014 at HP site. The wind folding resistance of each clone of typhoon Rammasun was in order No.73= No.75uff1eNo.10uff1eNo.71uff1eNo.16uff1eCK. It was short-term snowed at CX site December 2013. The cold resistance which was evaluated by survival rate were No. 10uff1eNo. 73uff1eNo. 16= No. 75uff1eCKuff1eNo. 71. According to the comprehensive evaluation of different weight of volume (60%), stem shape (20%), survival rate (10%) and stress resistance (10%), clone No.73was the best one, followed by No.71 and No.16.
This manual summarises information on the ecology and silviculture of the species Acacia mangium Willd, with an emphasis on Vietnam. It also encompasses growth and yield data from published sources, as well as collected from sites under smallholder industrial plantations in Phu Tho Province, Vietnam. This manual is 1 of 5 that guide smallholder tree planting of 5 selected tree species in Vietnam. The other 4 species are: Acacia hybrid, Cinnamomum parthenoxylon (Jack) Meisn, Erythrophloeum fordii Oliver and Eucalyptus urophylla S.T. Blake. The Government of Vietnam is carrying out a large-scale ‘reforestation’ programme, with the aim of improving local livelihood security, environmental sustainability and industrial wood supply. Smallholders are involved in plantation timber production through various schemes. Generally, these reforestation efforts have been effective, even though smallholders often lack the appropriate technical knowledge and management skills. Consequently, the quality and quantity of wood products may be suboptimal. The productivity of smallholder plantations can be improved by enhancing smallholders’ management knowledge and skills, including species selection (site matching), silvicultural management to produce high quality products, and pest and disease management.

It is increasingly recognized that the economic value of forests is not merely the production of timber. Forests provide other key ecosystem services, such as being sinks for greenhouse gases, hotspots of biodiversity, tourism and recreation. They are also vitally important in preventing soil erosion and controlling water supplies, as well as providing non-timber forest products and supporting the livelihoods of many local people. This handbook provides a detailed, comprehensive and broad coverage of forest economics, including traditional forest economics of timber production, economics of environmental role of forests, and recent developments in forest economics. The chapters are grouped into six parts: fundamental topics in forest resource economics; economics of forest ecosystems; economics of forests, climate change, and bioenergy; economics of risk, uncertainty, and natural disturbances; economics of forest property rights and certification; and emerging issues and developments. Written by leading environmental, forest, and natural resource economists, the book represents a definitive reference volume for students of economics, environment, forestry and natural resource economics and management.

Examines the consequences of 23 research projects funded by Canada's International Development Research Centre in developing countries. Shows how research influence public policy and decision-making and how can contribute to better governance.
The Vietnam Forestry Development Strategy (VFDS) is one of the country’s most important plans for the forestry sector. The strategic directions, objectives and solutions within it differ from time to time, depending on the political goals and perspectives of the moment, as well as the role that the forestry sector plays in Vietnam’s overall socio-economic development. Regardless of such changes, inheriting lessons learned, developing the next strategy off the back of the experience gained from solving previous challenges, and taking advantage of opportunities, are always the top priorities of the Government of Vietnam. This report is the result of a collaboration between the Center for International Forestry Research (CIFOR) and the Vietnam Administration of Forestry (VNFOREST); it is intended to provide VNFOREST with input as they develop the new strategy. Based on secondary document research and stakeholder interviews, the report reviews achievements and challenges in the implementation of VFDS 2006–2020, as well as provides recommendations for policy makers to consider in the process of developing the new strategy. Research results show that, by 2020, Vietnam had exceeded a number of the goals set out in VFDS 2006–2020, including: (i) accelerating the growth of production value in the sector; (ii) increasing the export value of wood and forest products; (iii) increasing domestic wood production; and (iv) planting protection forest (PTF) and special-use forests (SUF). However, the forestry sector still faces many challenges when it comes to other key performance indicators, such as: (i) increasing the area of production forests (PDF) with certification of sustainable forest management (SFM); (ii) increasing large-diameter timber production; (iii) increasing revenue for forest environmental services (FES); (iv) securing forest and forest land for the purposes of allocation and leases; (v) reducing the number of poor households in forestry areas; and (vi) increasing the rate at which forestry workers are trained. Although some anticipated targets were not achieved, others were exceeded, for example: forest cover; reforestation after logging; reduction of forest protection violations; and scattered tree planting. That these goals were achieved or exceeded is the result of strong political commitment, policies trend-matching the market, improvements in central and local management capacity, the active support of international donors, and the involvement of civil society and the private sector. That some targets were not achieved is due to the challenges of implementing policy effectively, efficiently and equitably at grassroots level, lack of resources and funding, and some ambitious goals and targets not being realistic in the current economic, political and market contexts. Addressing these challenges requires a new approach and more effective economic, social and technical solutions. Development of VFDS 2021–2030 and the 2050 vision needs to consider the implementation achievements and challenges of the previous policy, as well as how to align with global trends, and balance these with the current political, economic and social development context in Vietnam. The direction of the new strategy must also be considered in the context of international requirements, to facilitate the mobilization of domestic and foreign financial resources to help modernize the industry, as well as enhance the forestry sector’s role and value in terms of poverty reduction, sustainable economic development and ensuring sustainable forest ecosystems.
