About the project

The Pathways to Prosperity Gold programme has an overall goal of achieving a thriving ASGM sector that is economically profitable, socially responsible, and environmentally sound by 2029. The project aims to achieve this by having an increased number of ASGM with grown, diversified, sustainable and resilient mining businesses with improved working conditions, having a vibrant ASGM sector that has access to mining technologies, equipment and geological data and down and middle stream companies sourcing for sustainable and inclusive gold and investing in responsible mining businesses. Some of the activities that will be undertaken to achieve all of these outcomes include training and the provision of products and services (including access to finance), tailored to the needs of miners.

The Pathways to Prosperity (P2P) is a 7-year project being implemented by Solidaridad Kenya and Tanzania. The project is implemented in Geita and Shinyanga regions in Tanzania and in Migori, Narok, Kakamega, and Turkana Counties in Kenya.

The Pathways to Prosperity (P2P) project has invested in reducing mercury exposure and promoting sustainable artisanal and small-scale gold mining (ASGM) through improved retorts. One retort was distributed to each of the 60 participating mines in Kenya and Tanzania, along with user training manuals. This consultancy will therefore combine refresher training, behavior-change support, and demonstration of the environmental, social, and economic impacts of improved retort use. The assignment will generate an impact story to support project learning, accountability, and communication.

Objectives:

The overall objective of the consultancy is to strengthen and demonstrate sustained adoption of improved retorts among participating ASGM mines in Kenya and Tanzania and generate their environmental, social and economic impacts.

Specific objectives:

  • Refresh and strengthen miners’ knowledge and practical skills in the safe, consistent operation of improved retorts.
  • Determine the extent to which improved retorts are currently being used across the 60 participating mines in each country in collaboration with the project team.
  • Identify the technical, behavioural, economic, social and operational factors that enable or constrain consistent retort adoption.
  • Quantify reductions in mercury emissions and exposure associated with retort use.
  • Determine the social benefits of improved retort adoption for miners, processing workers, households and mining communities.
  • Determine potential economic benefits, including mercury recovery, reduced losses and other financial or productivity gains associated with retort use.
  • Generate evidence linking project retort activities to behavioural change and environmental, social and economic outcomes in collaboration with the project team.
  • Develop an impact story documenting the changes resulting from the intervention and lessons for future programming.
  • Provide technical advice to Solidaridad in relation to the related task whenever required

Scope of Work
