Asia is identified as one of the regions that will be hardest hit by climate variability and change that are projected to adversely affect many natural and human systems. The United Nations Framework Convention on Climate Change (UNFCCC) noted that Asia’s large population, the frequency of natural disasters in the region, and unplanned urbanization, with population relocation to coastal cities, are some of the factors that make Asia especially vulnerable to climate risks. Realizing these challenges, the Asia-Pacific Network for Global Change Research (APN) has been supporting various regional-based research and capacity building projects to enhance the interlinkages among science, policy and action for managing climate change risk in various sectors such as water, environment, and health, among others. To date, APN has supported more than 450 projects to various organizations in the Asia-Pacific region.

This special issue is composed of fifteen original articles contributed by the project leaders or members of the projects supported by APN over the last 5 years. The contributors to the issue were first invited to present in ‘International Symposium on Climate Change Impacts, Vulnerability and Adaptation: Asian Perspective’ on 16‒18 October, 2019 at the Asian Institute of Technology (AIT), Thailand.

The articles consist of climate change projections, assessment of climate change impacts on health, water resources (including groundwater) and its security, assessment of the resiliency of micro business, community and government entities to climate change and human development, and a knowledge synthesis of APN climate adaptation projects in Asia. The outputs of these articles are expected to support the formulation of adaptation policies to offset the negative impacts of climate change on natural and human systems, add value to the scientific literature, and help shape local, regional and global agendas on climate change.

亚洲被确定为受气候多变性和变化影响最大的地区之一，预计气候变化和变化会对许多自然和人类系统产生不利影响。《联合国气候变化框架公约》（UNFCCC）指出，亚洲人口众多，该地区的自然灾害频发，计划外的城市化以及人口迁移到沿海城市等，是使亚洲特别容易受到气候风险影响的一些因素。面对这些挑战，亚太全球变化研究网络（APN）一直在支持各种基于区域的研究和能力建设项目，以加强科学，政策和行动之间的相互联系，以管理水，环境，健康等等。至今，

该特刊由过去5年中由项目负责人或APN支持的项目成员撰写的15篇原创文章组成。该问题的撰稿人首先应邀参加于2019年10月16日至18日在泰国亚洲技术学院（AIT）举行的``气候变化影响，脆弱性和适应国际研讨会：亚洲视角''。

这些文章包括气候变化预测，气候变化对健康，水资源（包括地下水）及其安全性的影响评估，对微型企业，社区和政府实体对气候变化和人类发展的适应力评估以及知识的综合。 APN亚洲气候适应项目。预计这些条款的输出将支持制定适应政策，以抵消气候变化对自然和人类系统的负面影响，为科学文献增值，并帮助制定有关气候变化的地方，区域和全球议程。
