“…The reasons governments may consider mineral extraction illegal include the contractual status of the workforce, the existence of ties to drug or human trafficking, and their location in protected areas (Buxton, 2013; Zabyelina & van Uhm, 2020), which, in principle, renders these activities unviable for legalization. The line between formality and informality is hard to draw (Mosquera, 2006), since even concessions for industrial mining often operate in gray legal spaces, for example, when they overlap with protected areas (Armendariz‐Villegas et al, 2015) or encroach onto them, or resort to informal labor to outsource part of their activities (Geenen & Verbrugge, 2020). Definitions of what is illegal vary across countries.…”

Scholars of mining policies are beginning to understand how the most recent boom in commodity prices (2000–2014) influenced the institutional development of the mining sector in Latin America. We contribute to this literature by studying the design, dynamics, and outcomes of interorganizational coordination in Colombia and Ecuador. Our findings show that, despite their divergent policies, both countries failed to integrate the mining sector's three main policy games—formalizing artisan and small‐scale operations, increasing the number of large‐scale projects, and tackling illegal extraction. Several characteristics of the design of coordination initiatives influenced policy failure—the reliance on hierarchy mechanisms to motivate coordination, the lack of specificity of the coordination mandates, and the lack of specific resources for coordination. Contextual factors also shaped the dynamics and outcomes of coordination. The limited geographical spread of artisanal and small‐scale mining and of illegal extraction, the environmental sector's weakness, and the creation of a multilayered structure for public‐sector coordination contributed to policy effectiveness in Ecuador. On the other hand, the ample spread of artisanal and small‐scale mining and of illegal extraction, the lack of a clear coordinating structure, and the environmental sector's growing vigor contributed to sustained policy failure in Colombia.

“…The results showed the predominant impact of back contact for mineral and fossil depletion, human toxicity non-cancer and ecotoxicity. Back contact was made of gold, whose extraction procedure releases many toxic chemicals to the environment (cyanide and mercury, among others) and consumes many natural resources [57][58][59]. In scenario 3, the impact reductions were significant as a consequence of its reuse and recycling.…”

The environmental performance of four different device assembly procedures based on hybrid halide perovskite solar cell (PSC) were assessed from cradle to grave using life cycle assessment (LCA) methodology. In addition, a new environmental indicator was defined to measure the time evolution of an impact category, specifically in this case, human toxicity cancer payback time. PSCs procedures accounted for the probably three more used basic recipes for laboratory perovskite deposition: 1) spin coating of stoichiometric precursor solution, 2) spin coating of precursor solution using lead chloride precursor and 3) the two step deposition method. Also, the two most widely used substrate configurations (planar and mesoporous substrate) were considered. LCA included three realistic scenarios for the end of life: 1) residual landfill, 2) reuse and residual landfill and 3) reuse and recycling. The remaining variable parameters to assemble the device were fixed in common for all four devices, which were the major responsible of the whole PSC impact. Lead of PSCs had no significant contribution in environmental impacts. Beyond shared procedure steps, impacts generated by the twostep method and the use of mesostructured type substrate were higher. End of life scenario with reuse and recycling improved the toxicity impact categories.

“…Mexico is the second most populated country in Latin America 9 and one of the world s most biodiverse countries 10 . However, Mexico faces several serious pollution challenges from anthropogenic activities such as mining and agriculture, which affect biodiversity and ecosystems 11,12 . The country is the largest producer of silver in the world and a major global producer of gold, copper, and zinc, amongst other minerals 13 .…”

Mining is one of the main pollution issues worldwide, causing the greatest disturbances to the environment. Industrial and artisanal mining activities are widespread in Mexico, being a major global producer of various metals. This study aimed to assess the ecological impairments resulting from mining activities using the aquatic macroinvertebrates assemblages (MA). A multiple co-inertia analysis (MCOA) was applied to determine the relationships between environmental factors, habitat quality, heavy metals, and aquatic macroinvertebrates in two rivers of the Central Plateau, Mexico. The results revealed three contrasting environmental conditions and different MA. High concentrations of heavy metals, nutrients, and salinity limit the presence of various families of seemingly sensitive macroinvertebrates, these factors were identified as the drivers of structural changes in the MA, showing that not only mining activities, but also agriculture, and villages in the basin, exert negative effects to the macroinvertebrate communities. Diversity indices showed that the lowest diversity matched with both, the most polluted and the most saline rivers. The rivers studied displayed a high alkalinity and hardness, which can lead to the formation of metal precipitates and thus acting as a protection to aquatic biota. Aquatic biomonitoring in rivers, impacted by mining and other human activities, is critical for detecting the effect of metals and other pollutants to improve management and conservation strategies. This study supports the design of cost-effective and accurate water quality biomonitoring protocols in developing countries.
