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.

长江口岛屿湿地的底栖动物资源研究

调查了长江口3个岛屿湿地的底栖动物资源及其生态特征和环境功能。经鉴定底栖无脊椎动物有41种,优势种为河蚬(Corbiculafluminea)、焦河蓝蛤(Potamocorbulaustulata)、缢蛏(Sinonovaculaconstricta)、麂眼螺(Rissoinasp.)、光滑狭口螺(Stenothyraglabra)、谭氏泥蟹(Ilyrplaxdeschampsi)、无齿相手蟹(Sesarmadenaani)和天津厚蟹(Helicetridenstientsinensis)。讨论了底栖动物资源的主要生态学特征及其环境功能,提出了对底栖动物资源合理利用与保护的建议。     

二氧化氯预氧化工艺处理微污染黄河水研究

对二氧化氯预氧化工艺替代预加氯系统处理低温、含异味和较高色度的黄河原水进行了综合研究。与预氯化、混凝沉淀系统相比，二氧化氯预氧化、混凝沉淀系统对藻类的去除率提高了30％～40％，使嗅和味的阚值降低了10～20，但CODmn和氨氮的去除率的变化不明显。由于进水色度变化较大，对色度的去除率变化也不明显。运行证明，该系统改造后对降低以微污染黄河水为水源的北方给水处理厂冬季运行过程中的出水嗅和味的阚值、增加藻类的去除率具有明显的效果，同时，运行费用也较低。
