South American governments are moving to coordinate critical-mineral policy, with Chile, Argentina, Bolivia and Peru signing an Aug. 28 declaration on geology, regulation, suppliers, skills and financing, while Chile and Argentina revive a mining integration treaty that could unlock $20.7 billion and add 540,000 t/y of copper via cross-border projects such as El Pachón. Brazil’s new critical-minerals framework couples about $1 billion in tax incentives and a guarantee fund with tighter scrutiny of foreign partnerships and mining titles to expand refining, battery and magnet production. For engineers and operators, the opportunity lies in large copper, lithium and graphite reserves, but project viability will hinge on permitting timelines, fiscal stability and how far states push downstream value capture.

Revisions to England’s National Planning Policy Framework tighten requirements on flood risk assessment and sustainable drainage for new developments, but drainage specialists warn they cannot match the statutory control offered by implementing Schedule 3 of the Flood and Water Management Act. The updated NPPF strengthens policy wording on SuDS, runoff management and surface water exceedance routing, yet still relies on local planning authorities’ capacity and variable guidance. Practitioners are cautioned that, without Schedule 3’s mandatory approval bodies and adoption duties, long-term performance and maintenance of SuDS assets remain uncertain.

Colombia’s new government has repealed 10 resolutions restricting natural resource exploration and extraction, including measures like Decree 044 that allowed the Environment Ministry to freeze mining in sensitive ecosystems such as páramos for up to 10 years. Mining Minister Maria Nohemi Arboleda says the reforms will cut procedures, shorten licensing timelines and streamline community consultations, directly targeting Fraser Institute rankings that placed Colombia 57th for policy perception. The reset is aimed at unlocking up to $4 billion in copper-focused investment by 2030, with projects such as Quebradona, Alacrán, Mocoa and El Roble’s 4,200‑tonne‑per‑year output forming the early test case.
