Studying Land Use Change from ASGM - 2016
UNEP partnered with UNITAR's Operational Satellite Applications Programme (UNOSAT) to study land use change in ASGM regions in Central Kalimantan. The study used satellite imagery to detect changes over time, and illustrates high levels of recent deforestation and land clearing resulting from hydraulic mining in certain river valleys in the region. The study demonstrates than ASGM can significantly add to cumulative landscape impacts including from forestry and palm oil production.

Capacity-Building Phase 2 - 2015-2016
As a follow-up to the successful work in Phase 1 (see below), UNEP worked with Yayasan Tambuhak Sinta to build capacity for mercury-free ASGM methods and raise awareness on the risks of mercury use at the national, regional, and local level.
This project set up a mercury-free ASGM demonstration plant and training center in East Java, as well as convened two workshops for national and regional government officials to advance national action planning.

The project was funded by the Government of Norway.
Capacity-Building Phase 1 - 2012-2013
The project, led by Blacksmith Institute and Yayasan Tambuhak Sinta in
collaboration with UNEP and funded by the US Environmental Protection
Agency, gathered data on mercury releases from the ASGM sector and
brought together representatives from local and national Government,
local mining offices, research institutes and mining NGOs to develop a
national strategic plan for the sector considering broader sustainable
- Ten sluices, ninety retorts and fifty water-box condensers were
distributed to miners who had been trained in their use.
- In parallel
with this technical training, a number of events were held to raise the
awareness of miners and processors, health professionals, schoolteachers
and NGO leaders of the dangers of mercury use.
- Information materials
were developed with local community leaders so that appropriate messages
about mercury can be delivered to those at greatest risk of exposure.
- As a result of the project mercury releases to the environment were reduced by an estimated 3,000 kg in a single year by training small-scale gold miners in Indonesia to use improved processing techniques.
- The work to develop the National Strategic Plan to reduce mercury use from ASGM was initiated. The plan was finalized in 2014.
