The United Nations (UN) launched 17 Sustainable Development Goals (SDG) in 2015 to be achieved by 2030 for a sustainable future for all. These SDG provide a blueprint for a global plan of action, global peace and social-economic and environmental justice. Coal mining activities disturb the basic ecosystem and biodiversity of the land. The mining industry, being a temporary user of land, provides ample opportunities to reclaim mine degraded areas to help achieve the 17 SDG of the UN. Our current study aims to broaden understanding, explore and establish links between biochar-based coal mine restoration and the SDG, and, whenever possible, identify knowledge gaps and research needs. The SDG linked biochar-based mine restoration can be broadly divided into mitigation and enhancement roles, which can be further classified into direct, moderate and indirect activities. It has been observed that climate action (SDG 13), life on land (SDG 15) and affordable and clean energy (SDG 7) were benefited by biochar-based restoration. Biochar application improves the physico-chemical, biological and nutritional properties of the impoverished mine spoil and promotes plant growth. Biochar application reduces the bulk density by 3%–31%, increases the porosity by 14%–64%, pH 1.4–2.5 times and aggregates stability by 3%–226% along with improvements of plant nutrient (NPK). The study showed tremendous opportunities for using biochar-based coal mine restoration to help achieve each of the SDG.

生物炭辅助煤矿退化土地生态恢复以实现联合国可持续发展目标

联合国 (UN) 于 2015 年启动了 17 个可持续发展目标 (SDG),将在 2030 年实现,为所有人创造可持续的未来。这些可持续发展目标为全球行动计划、全球和平以及社会经济和环境正义提供了蓝图。煤炭开采活动扰乱了土地的基本生态系统和生物多样性。采矿业作为土地的临时使用者,为开垦退化的矿山提供了充足的机会,以帮助实现联合国的 17 项可持续发展目标。我们目前的研究旨在扩大理解、探索和建立基于生物炭的煤矿恢复与可持续发展目标之间的联系,并在可能的情况下确定知识差距和研究需求。与可持续发展目标相关的基于生物炭的矿山恢复可以大致分为缓解和增强作用,可以进一步分为直接、适度和间接的活动。据观察,气候行动(可持续发展目标 13)、陆地生命(可持续发展目标 15)和负担得起的清洁能源(可持续发展目标 7)都得益于基于生物炭的恢复。生物炭的应用改善了贫瘠矿山弃土的理化、生物和营养特性,促进了植物生长。生物炭的应用使堆积密度降低 3%–31%,孔隙率增加 14%–64%,pH 值增加 1.4–2.5 倍,聚集体稳定性增加 3%–226%,同时植物养分 (NPK) 得到改善。该研究显示了使用基于生物炭的煤矿恢复来帮助实现每个可持续发展目标的巨大机会。生物炭的应用改善了贫瘠矿山弃土的理化、生物和营养特性,促进了植物生长。生物炭的应用使堆积密度降低 3%–31%,孔隙率增加 14%–64%,pH 值增加 1.4–2.5 倍,聚集体稳定性增加 3%–226%,同时植物养分 (NPK) 得到改善。该研究显示了使用基于生物炭的煤矿恢复来帮助实现每个可持续发展目标的巨大机会。生物炭的应用改善了贫瘠矿山弃土的理化、生物和营养特性,促进了植物生长。生物炭的应用使堆积密度降低 3%–31%,孔隙率增加 14%–64%,pH 值增加 1.4–2.5 倍,聚集体稳定性增加 3%–226%,同时植物养分 (NPK) 得到改善。该研究显示了使用基于生物炭的煤矿恢复来帮助实现每个可持续发展目标的巨大机会。
