Development of regional climate mitigation baseline for a dominant agro-ecological zone of Karnataka,India

Setting a baseline for carbon stock changes in forest and land use sector mitigation projects is an essential step for assessing additionality of the project. There are two approaches for setting baselines namely, project-specific and regional baseline. This paper presents the methodology adopted for estimating the land available for mitigation, for developing a regional baseline, transaction cost involved and a comparison of project-specific and regional baseline. The study showed that it is possible to estimate the potential land and its suitability for afforestation and reforestation mitigation projects, using existing maps and data, in the dry zone of Karnataka, southern India. The study adopted a three-step approach for developing a regional baseline, namely: (i) identification of likely baseline options for land use, (ii) estimation of baseline rates of land-use change, and (iii) quantification of baseline carbon profile over time. The analysis showed that carbon stock estimates made for wastelands and fallow lands for project-specific as well as the regional baseline are comparable. The ratio of wasteland Carbon stocks of a project to regional baseline is 1.02, and that of fallow lands in the project to regional baseline is 0.97. The cost of conducting field studies for determination of regional baseline is about a quarter of the cost of developing a project-specific baseline on a per hectare basis. The study has shown the reliability, feasibility and cost-effectiveness of adopting regional baseline for forestry sector mitigation projects.

“三水”统筹视角下京津冀地区城市水生态环境保护策略分析

明确京津冀地区水生态环境保护方向与策略,对于实现京津冀水生态环境保护和高质量协同发展,以及2035年美丽中国建设目标具有重大意义.在水资源、水环境、水生态的“三水”统筹视角下,面向京津冀地区水生态环境管理问题和需求,以重点城市作为基本分析单元,从“三水”以及社会经济发展水平、污染物排放量和环境治理力度这6个维度研究构建水生态环境保护策略分析体系,为量化水生态环境保护水平提供逻辑框架.在设立理想值的基础上应用PROMETHEE-GAIA方法分析京津冀各城市水生态环境现状与理想值之间的差距,因地制宜制定各个城市水生态环境保护策略.结果显示水生态环境保护综合水平从高到低依次为：北京市>天津市>秦皇岛市>衡水市>张家口市>廊坊市>净流(Phi)均值>邯郸市>承德市>沧州市>保定市>唐山市>石家庄市>邢台市,各城市水生态环境保护水平距离理想值仍有不小的差距;分别从单维度和单指标层次分析得到各城市水生态环境保护的优势和劣势,在此基础上,提出京津冀区域城市未来水生态环境保护策略,助力京津冀地区水生态环境保护.     

On integration of policies for climate and global change

Currently envisaged mitigation of greenhouse gases (GHG) emissions will be insufficient to appreciably limit climate change and its impacts. Adaptation holds the promise of ameliorating the impacts on a small subset of systems being affected. There is no question that both will be needed. However, climate change is only part of a broader multi-stress setting of global through to local changes. Privileging climate related policies over other concerns leads to tragic outcomes. Climate policies need to be designed for and integrated into this broader and challenging context. This paper focuses on placing climate change within the broader context of global change and the importance of aligning climate policy objectives with the myriad other policies that still need to be implemented if our primary goal is improving human welfare rather than limiting our focus to climate change and its impacts.

不同类型国家资源战略实施的启示及我国资源战略的选择

资源战略是经济发展战略的重要组成部分。不同的国家有着不同的资源战略。本文通过对不同类型国家资源战略实施成败的分析,从中总结了３点有益的启示：①世界经济发展中的相互依赖越来越强;②资源战略的选择要符合本国的实际;③经济结构要多样化。本文还对我国高耗、低效、封闭式的资源战略的形成作了深入的分析,并提出了我国资源战略选择的４个主要方面：①多样化是中国资源战略的出发点;②充分利用国内资源,积极利用国外资源是我国资源战略的核心;③保护资源与环境是我国资源战略的重要组成部分;④建立资源节约型国民经济体系,是我国资源战略的目标。
