Beat Plastic Pollution

The world united around the slogan “Beat Plastic Pollution” on World Environment Day. The slogan, motivated by increasing awareness of the vast volume of plastic – discarded, bottles, bags, straws, and discarded items – that reach the world’s oceans, draws attention to the impact of plastic on aquatic life. Let us take a moment to reflect on the relevance of the theme to our mountains.

As mountain areas change, as manufactured goods and visitors from outside flood mountain villages, towns, and trekking routes in increasing numbers, many places find themselves overwhelmed by indiscriminately discarded garbage. From the kora around Mt Kailash to the slopes of Mt Everest, the natural beauty of these landscapes are blighted by unsightly piles of wrappers, bottles, bags, and other garbage. The problem is even more acute in our cities.

Some of the garbage from our mountain areas make it into our river systems and eventually to the oceans. The bits that stay behind in the mountains also cause severe problems – ranging from local soil and water pollution to dangerously high levels of air pollution resulting from emissions caused by burning plastics. Unfortunately, the practice of setting piles of garbage on fire is very common in the region and often done in the mornings and evenings when smoke spreads horizontally, into homes and lungs. Burning plastic releases large quantities of toxins as well as black carbon, as we recently discovered in a study coordinated by the International Centre for Integrated Mountain Development (ICIMOD). Black carbon warms the atmosphere and contributes to the melting of Himalayan glaciers and snowfields.

The problem and its solutions can be found at several levels. First, garbage is poorly managed in many of our communities. Compostable and non-compostable materials are not separated. Collection is unreliable and insufficient, so that much of the garbage ends up piled on street sides where they burned. That garbage that is collected often ends up in poorly managed landfills that leach out dirty water and emit large amounts of methane into the air, which also contributes to climate warming. ICIMOD’s Transboundary Landscape Programme has been working with communities around Mt Kailash to set up locally managed garbage management and sanitation solutions.

Second, there is a strong need for increased awareness and behavioural change. The theme for World Environment Day this year discourages single-use plastic items. There are easy alternatives to using disposable cups, plates, cutlery, and straws, and plastic shopping bags. It usually takes very little effort for someone to use a more sustainable alternative. What is needed is awareness and a willingness to change habits.

Third, businesses can steer people towards more sustainable behaviour through their products and pricing. Often, the amount of packaging on any product can easily be decreased without compromising the product itself. Hotels can provide bulk shampoo instead of small single-use bottles. Increasing numbers of shops do not give out plastic bags for free anymore.

Fourth, local and national governments have a lot of power to change individuals’ behaviours to decrease the production of plastic waste. Increasing numbers of places are banning single-use plastic and plastic bags outright while in other places, governments have mandated that consumers pay extra for them.

As an intergovernmental organization working on issues of environment and sustainability from the high Himalaya all the way down to the oceans, ICIMOD needs to set an example. As we mark World Environment Day, ICIMOD bans all single-use plastic and all open fires from the ICIMOD campus as well as from all ICIMOD-organized events. We encourage all ICIMOD staff to pledge to do the same in their homes.

2023年国际山岳日:恢复山地生态系统

山地被广泛认为是生物多样性的发源地,其陡峭的斜坡孕育了各种繁复的生命形式。这些地区作为自然的庇护所变得愈发重要:虽然它们只占据了地球总面积的四分之一,却容纳了地球上85%的两栖动物、鸟类和哺乳动物。这种丰富的自然资源在联合国教科文组织的738个全球生物圈保护区中得到体现,其中明显超过一半位于山区。 然而,令人担忧的是,这些自然资源的非凡丰富正面临威胁。过去,由于偏远或地形困难,山地得以免受人类干扰,但如今这种状况逐渐减少。曾经被视为大自然摇篮和避难所的山地正在逐渐转变成墓地。在兴都库什-喜马拉雅地区,上个世纪就已经失去了70%的生物多样性。这些损失,包括物种的灭绝,如今正以加速度增长,正如ICIMOD的重要评估报告《兴都库什喜马拉雅的水、冰、社会和生态系统》(简称《HIWISE报告》)所指出的那样。 在公众、政治和外交层面,人们越来越认识到自然是我们当前危机中最重要的解决方案之一。联合国已宣布2021-2030年为生态系统恢复十年,去年,《昆明-蒙特利尔全球生物多样性框架》的指导下,全球100多个政府承诺在2030年之前将30%的陆地和海洋保留给自然,其中包括兴都库什-喜马拉雅地区。今年,在联合国全球气候大会COP28上,自然首次成为讨论的核心议题。 这些努力,以及今年国际山岳日的“生态系统恢复”主题,为恢复和保护山区景观提供了迫切需要的推动力。那么,我们的八个成员国离实现“30x30”目标有多近呢?到目前为止,不丹是唯一一个实际超额达标的国家,其51.4%的土地面积已经属于各种保护区类别。 尼泊尔只有不到24%的土地受到保护;中国仅为16%,略高于目标的一半;巴基斯坦占12%;印度为8%;缅甸为7%;孟加拉国为5%,阿富汗为4%。 令人担忧的是,在整个兴都库什-喜马拉雅地区,自然资源仍然丰富的关键区域仍处在保护之外:67%的生态区、39%的生物多样性热点、69%的关键生物多样性区域以及76%的重要鸟类和生物多样性区都没有得到保护。 现有的保护区域犹如在人类改变过的景观中的“孤岛”,缺乏与其他保护区域的连通走廊,无法满足广泛分布的物种需求,并且面临非法捕猎、侵占和资源开采的压力。现有的保护区域不足以确保成功保护我们地区的象征性物种,包括亚洲象、独角犀牛和孟加拉虎。 一个尚未尝试的解决方案是建立跨界生物圈保护区,这将允许在景观层面进行综合保护。实现这一目标需要跨越国家边界的共同政治承诺,并在共享生态系统的管理方面展开合作。ICIMOD将积极推动我们区域成员国接受这一解决方案。 然而,底线是,要扭转自然的损失,我们必须对其进行估值并提供相应的资金支持。只要经济学家继续将其价值定为零,就不会引起足够的重视。在进行估值之前,拥有大量自然资本但经济欠发达的国家将因为缺乏3A信用评级而难以以较低贷款利率借款。必须为该地区的国家提供更便宜的资本来促使自然的恢复:这是ICIMOD将与我们的成员、多边开发银行和其他机构紧急合作推进的事项。为了防止地球系统完全崩溃,我们必须为大自然提供一个适宜的生存环境,这一观点从未像现在这样显而易见。
