HakiRasilimali is a platform of civil society organisations (CSOs) working on strategic issues around minerals, oil and gas extraction in Tanzania. The platform emerged from an online “Knowledge Community of Practitioners” in the extractive industries in 2010 to its current status as a joint learning and advocacy platform. The platform seeks to effectively influence extractive industries related policies, laws and practices in the country by adopting a strategic and proactive approach. This involves building a formal coordination mechanism for strategic and improved advocacy in extractive industries. HakiRasilimali is affiliated with Publish What You Pay (PWYP), a global membership-based coalition of civil society organisations (CSOs) in over 40 countries.
