Mitigation and adaptation synergy in forest sector

Mitigation and adaptation are the two main strategies to address climate change. Mitigation and adaptation have been considered separately in the global negotiations as well as literature. There is a realization on the need to explore and promote synergy between mitigation and adaptation while addressing climate change. In this paper, an attempt is made to explore the synergy between mitigation and adaptation by considering forest sector, which on the one hand is projected to be adversely impacted under the projected climate change scenarios and on the other provide opportunities to mitigate climate change. Thus, the potential and need for incorporating adaptation strategies and practices in mitigation projects is presented with a few examples. Firstly, there is a need to ensure that mitigation programs or projects do not increase the vulnerability of forest ecosystems and plantations. Secondly, several adaptation practices could be incorporated into mitigation projects to reduce vulnerability. Further, many of the mitigation projects indeed reduce vulnerability and promote adaptation, for example; forest and biodiversity conservation, protected area management and sustainable forestry. Also, many adaptation options such as urban forestry, soil and water conservation and drought resistant varieties also contribute to mitigation of climate change. Thus, there is need for research and field demonstration of synergy between mitigation and adaptation, so that the cost of addressing climate change impacts can be reduced and co-benefits increased.

Catalytic dechlorinafion of o-chlorophenol by nanoscale Pd／Fe

Transformation of chlorophenols by nanoscale bimetallic particles represents one of the latest innovative technologies for environmental remediation. Nanoscale Pd/Fe bimetallic particles were synthesized in the laboratory for treatment of o-chlorophenol. Most of the nanoscale particles are in the size range of 20-100 nm. BET specific surface area of the nanoscale Pd/Fe particles is 12.4 m2/g. In comparison, a commercially available Fe powder( < 100 mesh) has a specific surface area of just 0.49 m2/g. Batch experiments demonstrated that the nanoscale Pd/Fe bimetallic particles can effectively dechlorinate o-chlorophenol. Dechlorination efficiency is affected by the mass fraction of Pd in the bimetal, nanoscale Pd/Fe mass concentration and mixing intensity.     

耐热粉末铝合金筒体热旋成形试验

介绍了喷射沉积耐热铝合金管坯经挤压变形 ,变薄旋压筒体的研制过程 ;重点论述了热旋成形筒体的工艺路线。试验探讨了耐热铝合金的旋压温度为 35 0～ 45 0℃ ,道次变薄率约为2 0 % ,累计变薄率约 5 0 % ,需中间退火 ,退火温度宜取 35 0℃。热旋结果认为 ,喷射沉积耐热粉末铝合金铸坯直接热旋成形困难 ,需经挤压比大于 4的变形致密 ,有助于热旋成形。耐热粉末铝合金挤压坯加热变薄旋压 ,应采用小压下量多道次的变形过程 ,逐渐细化晶粒组织 ,才能旋出综合性能良好的筒形件。
