Valuing water in the HKH

On 22 March each year, World Water Day reminds us of the important role that water plays in society and in the natural world. The theme for World Water Day 2021 is “valuing water”. The United Nations, sponsor of World Water Day, points out that the valuation of water includes economic definitions but extends far beyond to embrace social and cultural values from many personal and societal perspectives. So, on a day like World Water Day, we at ICIMOD ask from an institutional perspective: How do we value water?

An initial answer is an implicit one: We often convey the scope and importance of our work in terms that are defined by, or are influenced by, water. When describing our regional mandate, we depict the HKH as the water tower of Asia that supplies water for 1.9 billion people. The gravity of the issue of climate change is starkly illustrated by descriptions of receding glaciers and drying springs across the HKH. The value of water is further demonstrated through the content of our work: Water components are embedded in nearly every regional programme and theme in our institutional structure.

It is through our research and implementation, alongside our partners, that the value of water comes into sharper focus through more explicit forms of valuation as well. In our work, this valuation can take various forms. Quantifiable economic valuation, such as estimates of the productivity or the marginal value of water, may result from analyses of situations where water is scarce or where there are competing uses. In the HKH, this valuation might include water uses that are ubiquitous across mountains and lowlands alike, such as water supply, ecosystem services, and irrigation, but also water uses and hydrologic processes associated with mountains specifically, such as hydropower and changes in glacier mass, that may impact water supply downstream in the future. However, the concept of water valuation must not be limited to beneficial uses of water. Water can have “negative” value as well. Consider, for example, the economic damage caused by glacial lake outburst floods, an active area of our research, or the recent flood caused by a massive rockslide in Uttarakhand, India, that resulted in the loss of lives and the destruction of hydropower facilities.

Yet, some values of water defy quantification. How do we quantify the value of monsoonal rainfall in supporting biodiversity hotspots in the HKH, the social and cultural value of mountain springs in supporting a way of life for mountain peoples, or the intrinsic value that snow-capped ridges yield for ecotourism? These intangible values of water must also be considered and are integral to the work ICIMOD does to improve the wellbeing of people and the environment in the HKH.

World Water Day this year is about “valuing water”. In the end, only by holistically considering the value placed on water from all of its users and across all of its dimensions of its use and impact, whether those values can be quantified or remain intangible, can we approach a true valuation of water in the HKH. This is precisely our aim at ICIMOD. Let us acknowledge the value that water holds in our lives, in the HKH and across the globe.

确保空气洁净蓝天:紧急呼吁全球空气污染公约

近期的空气质量寿命指数(AQLI)报告标题为:“空气污染是地球上人类预期寿命面临的最大外部威胁”。这一严厉警告应该足以激励全球采取行动应对这一最严重且无处不在的威胁。然而,目前还没有专门针对这一“沉默杀手”的全球合作框架或公约。据世界卫生组织称,每年有 700 万人过早死亡与空气污染有关,这比迄今为止死于 Covid-19 的人数还多,而且根据该报告,空气污染对普通人的健康危害比吸烟或酗酒还大。为纪念今年国际清洁空气蓝天日,我紧急呼吁全球和地区领导人建立应对空气污染的全球合作框架。该框架应与解决“三重地球危机”的其中两个要素——气候变化和生物多样性丧失——的框架保持一致。 兴都库什-喜马拉雅地区受到的空气污染的严重影响,根源有很多,包括:机动车辆、工业、焚烧固体生物燃料、农作物秸秆和家庭废物。重要的是,这类受污染的空气并不是某个城市、地区或国家特有的,而是整个印度河-恒河平原和喜马拉雅山麓——横跨北印度次大陆和山脉的数十万平方公里的区域——所共有的。该地区空气中的悬浮颗粒经常超过安全水平,影响着居住在这里的大约十亿人。 正如联合国空气污染倡议所解释的,颗粒物是微小的污染颗粒,这些微小、肉眼看不见的颗粒污染物会深入我们的肺部、血液和身体。约三分之一的中风、慢性呼吸道疾病和肺癌死亡病例以及四分之一的心脏病死亡病例都因这些污染物造成。阳光下许多不同污染物相互作用产生的地面臭氧也是哮喘和慢性呼吸道疾病的原因之一。 美国芝加哥大学能源政策研究所发布的空气质量寿命指数报告显示:“如果污染水平将持续,孟加拉国、印度、尼泊尔和巴基斯坦的居民预计平均寿命会缩短约 5 年。” 报告继续指出,“亚洲和非洲负担最重,但缺乏关键基础设施”。尽管如此,我们还是有理由希望在我们的地区找到可能的解决方案,因为中国在空气污染防治的努力仍然取得了显着成功,而且工作仍在进行中。正如该报告所述,“自 2013 年(即中国开始“反污染之战”的前一年)以来,中国的污染已下降了 42.3%。由于这些改善,如果减排持续,中国公民的平均寿命预计会延长 2.2 年。”
