These conditions make small-scale mining communities more vulnerable to natural disasters. In the Philippines, artisanal and small-scale gold mining (ASGM) is practiced in more than 30 provinces across the country, employs around 300,000 to 500,000 miners, and supports the livelihood of another two million people nationwide. But with the recent ...

1. Introduction. All over the world, ASGM has evolved from being a purely manual and labour-intensive activity (Yego et al., 2018) to being a small-scale or even larger-scale activity that is mechanised and uses advanced techniques and technologies, such as excavators and dredges for extraction and cyanidation for processing (Verbrugge et al., 2021).
The sheer scale of the ASM sector is also reflected in its GDP contribution, compared to that of formalised miners. The ARM report estimates that, based on extrapolating known data for the whole of Kenya, the ASM gold sector alone contributes around $224m to the national economy, worth around 0.35% of total Kenyan GDP and over half of the total GDP …

Note that at this time gold was produced by local miners using traditional mining techniques that will in todays's terminology be referred to as artisanal and small-scale Mining (ASM). 2 Thomas Bowdich, a British envoy, was one of the first Europeans to venture into the interior of Africa's fabled Gold Coast, in 1817.
ASM has operated for centuries as a small unorganized and informal activity. For example, Allchin discusses small- and large-scale gold mining that operated in India from 100 BCE to 300 CE.
