Abstract

The island of El Hierro is the smallest and youngest island in the Canary archipelago. It has been recognized as a UNESCO Biosphere Reserve since 2000, and it has a population of approximately 10,000 inhabitants. The aim of this study was to determine the amount of CO2 emissions absorbed by the forest stands of the island of El Hierro and compare it to the emissions generated by the population. It is noteworthy that there is a hydro‐wind energy production project on the island that has significantly minimized the emissions linked to energy production. In short, El Hierro's forest stands are capable of capturing 46,785 tons of CO2 annually, while emissions associated with electricity production and emissions linked to road mobility are below the island's carbon sequestration capacity since the Gorona del Viento renewable energy project was built. By working on investment in renewable energies to produce energy and changing mobility with the use of electric vehicles, a small island like El Hierro can adapt to ecological transition by the year 2040. This is a goal set by the government to drastically reduce emissions in the Canary Islands.

利用 100% 的可再生能源和作为碳汇的森林实现岛屿的碳中和：埃尔希耶罗岛（加那利群岛）作为欧洲的试点

埃尔希耶罗岛是加那利群岛中最小、最年轻的岛屿。自 2000 年起，该岛被联合国教科文组织认定为生物圈保护区，岛上人口约为 10,000 人。这项研究的目的是确定埃尔希耶罗岛林木吸收的二氧化碳排放量，并将其与人口产生的排放量进行比较。值得注意的是，岛上有一个水力风能生产项目，大大减少了与能源生产相关的排放量。简而言之，埃尔希耶罗的森林每年能够捕获 46 785 吨二氧化碳，而自 Gorona del Viento 可再生能源项目建成以来，与电力生产相关的排放量和与道路交通相关的排放量均低于该岛的碳螯合能力。通过投资可再生能源来生产能源，并通过使用电动汽车来改变交通方式，像埃尔希耶罗这样的小岛可以在 2040 年之前适应生态转型。这是政府为大幅减少加那利群岛排放量而设定的目标。

期刊介绍： Soil Use and Management publishes in soil science, earth and environmental science, agricultural science, and engineering fields. The submitted papers should consider the underlying mechanisms governing the natural and anthropogenic processes which affect soil systems, and should inform policy makers and/or practitioners on the sustainable use and management of soil resources. Interdisciplinary studies, e.g. linking soil with climate change, biodiversity, global health, and the UN’s sustainable development goals, with strong novelty, wide implications, and unexpected outcomes are welcomed.
