About Us Global Perspectives Initiative

Global Gold Production Touching Ground. In recent decades, gold mining has moved into increasingly remote corners of the globe. Aside from the expansion of industrial gold mining, many countries have simultaneously witnessed an expansion of labor-intensive and predominantly informal artisanal and small-scale gold mining.

While plastic wastes in the environment is truly a global and multi-media issue, popular press and scientific attention has predominantly been ocean-centric e.g. Cole et al., 2011. Like climate change and persistent organic pollutants, plastic debris exemplifies our capacity to alter the environment on a global scale.

Mineral Resources Evaluation with Mining Selectivity and

May 26, 2020 The most common approach used in the mining industry for mineral resources modeling is to estimate the grades using ordinary kriging and report the recoverable resources based on this deterministic estimated model. Mineral resources calculated with kriging are a smooth representation of the actual distribution of grades and do not provide an assessment of uncertainty. Unlike kriging ...

Jul 18, 2017 Liberia is endowed with an impressive stock of mineral reserves and has traditionally relied on mining, namely iron ore, gold, and diamonds, as a major source of income. The recent growth in the mining sector has the potential to contribute significantly to employment, income generation, and infrastructure development. However, the development of these mineral resources has significant ...

Mar 03, 2009 We estimate that artisanal and small scale gold mining releases between 640 to 1350 Mg of mercury per annum into the environment, averaging 1000 Mg yr -1, from at least 70 countries. 350 Mg yr -1 of this are directly emitted to the atmosphere while the remainder 650 Mg yr -1 are released into the hydrosphere rivers, lakes, soils, tailings.

World emissions of mercury from artisanal and small scale

The IAASTD clearly debunks the myth that industrial agriculture is superior to small-scale farming in economic, social and ecological terms. The report argues for a new paradigm for agriculture in the 21st century, which recognises the pivotal role that small-scale farmers play in feeding the world population.

Challenges of Women in Small Scale Oil Palm Production

Challenges Faced by the Isalu Women in Oil Palm Production. The economic role of the Isalu women in farming cannot be compared with that of men. The labour of women starts from the time of cultivation to the time of marketing of the farm products. Most Isalu women have no personal land for farming.
