There is significant momentum behind natural gas extraction efforts in the United States, with many states viewing it as an opportunity to create jobs and foster economic growth. Natural gas extraction has also been championed as a way to move toward domestic energy security and a cleaner energy supply. First demonstrated in the 1940s, hydraulic fracturing—injecting fracturing fluids into the target formation at a force exceeding the parting pressure of the rock (shale) thus inducing a network of fractures through which oil or natural gas can flow to the wellbore—is now the predominant method used to extract natural gas in the United States.

This paper describes the specific activities undertaken as part of an integrated assessment on artisanal and small-scale gold mining activities in Ghana.
An assessment of the potential ecological risk of heavy metals and a metalloid in agricultural soils in 19 communities in Tarkwa, Ghana.
This article describes a modified Delphi approach in which 27 multi-disciplinary academics and 22 stakeholders from Ghana and North America were polled about ways to address negative effects of small-scale gold mining (ASGM) in Ghana.
This report is part of the Hydraulic Fracturing in Michigan Integrated Assessment (IA) which began in 2012. The guiding question of the IA is, “What are the best environmental, economic, social, and technological approaches for managing hydraulic fracturing in the State of Michigan?”
The purpose of the IA is to present information that:
- expands and clarifies the scope of policy options, and
- allows a wide range of decision makers to make choices based on their preferences and values.
As a result, the IA does not advocate for recommended courses of action. Rather, it presents information about the likely strengths, weaknesses, and outcomes of various options to support informed decision making.

A multiple media exposure assessment and cross-sectional study of mercury conducted in 2010 through 2012 in northeast Ghana with a small-scale gold mining community, Kejetia, a subsistence farming community, Gorogo, and an urban ASGM gold refinery in Bolgatanga.
This study assessed levels of heavy metals in drinking water sources in two small-scale mining communities (Nangodi and Tinga) in northern Ghana.
The study offers a retrospective, cross sectional examination of the records of injuries of artisanal and small-scale gold miners in the Eastern Region of Ghana from 2006 to 2013.
The agriculture sector is increasingly impacted by climate change. Variable weather patterns, soil erosion, and industrial agricultural practices have caused considerable damage to the farming community, particularly in developing countries. However, mobile and other technological developments provide an opportunity to improve agricultural practices in developing countries and facilitate better adaptation to climate change.
