Mining in Morobe, Papua New Guinea: Impacts from Mining Along the Watut River, MPI, 2014 Final Watut River - Caleb Ham

This report is about the impact of mining on communities living along the Watut River and in the Morobe Province of Papua New Guinea. Given that similar reports could also be written about other mines it is also a report that applies more applies more widely to the PNG mining industry. While the impacts from mining on the Watut River are minor in comparison to those at Porgera, Ok Tedi and Panguna, they are nonetheless serious. Serious because of the impacts on local people, the repetition of past mistakes and as an example of the slow progress of reform in the mining industry.

The impetus for this report comes from many sources. For the Mineral Policy Institute it is a continuation of our work on a range of mine-sites and mining related impacts in Papua New Guinea since 1995. Watut River Communities became increasingly concerned about riverine impacts from the Hidden Valley mine since construction commenced and asked MPI to assist in late 2010. Subsequently, in early 2012 MPI was commissioned by the Lutheran Evangelical Church of Papua New Guinea, with support from Mission EineWelt in Germany to assess impacts from mining in the Watut River region.

Mining in Morobe, Papua New Guinea – Impacts, Assurance and Self-determination, G M Mudd and C P Roche ,2014

The Morobe Province of central Papua New Guinea (PNG) has been mined for gold for nearly a century, although it is only in the past decade that large-scale modern mining commenced. This paper presents the results of an ongoing project in the Morobe Province conducted by the Mineral Policy Institute examining the historical, current and future impacts of mining, including community views, social and environmental impacts and the monitoring and regulation of mining.
