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.     

在波罗的海不同的气候条件下模拟的海面温度和热通量

本文使用由不同的全球模拟所产生的区域性耦合海洋-大气模型,通过数值模型试验探讨了波罗的海气候未来可能的物理状况.将一些情景以及近来的一些气候模拟情况作了比较,以估计气候变化.海面温度总体平均明显地增高2.9℃.平均年平均增温的水平模式主要可由冰盖的减少解释.由大气向波罗的海的热输送表现出季节性变化周期秋季热损失减少,春季热吸收增加,夏季热吸收减少.年际间海面温度的变化一般是在增加.这与北部一些中平滑的频率分布有关.全部热收支表示出海面太阳辐射在增加,而太阳辐射增加由热通量其他组成成分的变化所平衡.
