“…This phenomenon occurs under natural conditions and on a large scale results in deposit formation ( Neiva et al., 2019 ). In the actual environment, there are cases where the concentration of trace elements in the river basin around the mine increased due to the mineralization, which had an environmental impact over a wide area too ( Kosai et al., 2021 , Peter and Patrick, 1994 ). Willy at al.…”

River sediments have the effect of aggregating geochemical environmental information, such as that related to geological and artificial pollution resulting from mine closure. This information comprises high-dimensional data and is related to the distribution and quantities of elements in river sediments. However, accessing and interpreting this geochemical information can be difficult. This study employed a data-driven analysis that can be mathematically and statistically reduced in dimension. Using high-dimensional geochemical and environmental information on river sediments, this study evaluated the environmental impact of closed mines. Sample for analysis were collected from three rivers. There are differences in the existence of mines and mine wastewater treatment methods in this river. A total of 33 elements were measured in river sediments. Frequency distribution analysis and Principal component analysis revealed that the elements had unique distribution and frequency characteristics in each river catchment. Four environmental factors could be extracted from the relationship of elements due to lower dimension. PC1 was influenced by the land use in the river area. PC2 captured the geological background. PC3 captured the mixing-diluting effect that occurs in rivers. PC4 effectively captured the effects of domestic wastewater and the effects of closed mines. The effects of the closed mines could be confirmed using the PC4 score for the Okawa River and the Akagawa River. By examining the elemental relationships obtained using these mathematical methods, it is possible to infer the effect of geological features and mines on sediment physiochemistry using existing data on river sediments.

“…However, their implementation requires specific minerals, and mining for those minerals has potential for large detrimental environmental and societal impacts. The total lifecycle material resources required for lithium batteries, for instance can exceed the weight of the battery itself by nearly 200 times (Kosai et al, 2020). Demand for lithium may surpass supply already by the mid‐2020s (Anwani et al, 2020; Wanger, 2011).…”

A multitude of actions to protect, sustainably manage and restore natural and modified ecosystems can have co‐benefits for both climate mitigation and biodiversity conservation. Reducing greenhouse emissions to limit warming to less than 1.5 or 2°C above preindustrial levels, as outlined in the Paris Agreement, can yield strong co‐benefits for land, freshwater and marine biodiversity and reduce amplifying climate feedbacks from ecosystem changes. Not all climate mitigation strategies are equally effective at producing biodiversity co‐benefits, some in fact are counterproductive. Moreover, social implications are often overlooked within the climate‐biodiversity nexus. Protecting biodiverse and carbon‐rich natural environments, ecological restoration of potentially biodiverse and carbon‐rich habitats, the deliberate creation of novel habitats, taking into consideration a locally adapted and meaningful (i.e. full consequences considered) mix of these measures, can result in the most robust win‐win solutions. These can be further enhanced by avoidance of narrow goals, taking long‐term views and minimizing further losses of intact ecosystems. In this review paper, we first discuss various climate mitigation actions that evidence demonstrates can negatively impact biodiversity, resulting in unseen and unintended negative consequences. We then examine climate mitigation actions that co‐deliver biodiversity and societal benefits. We give examples of these win‐win solutions, categorized as ‘protect, restore, manage and create’, in different regions of the world that could be expanded, upscaled and used for further innovation.
