This is the third publication in a series dedicated to documenting and analyzing the evolution of the Trilateral South-South Cooperation project, titled “Improvement of Water, Sanitation, and Hygiene Services in Angola through Trilateral South-South Cooperation”. The project focuses on introducing an innovative approach to simplified sanitation and integrated solid waste management (ISWM) in Angola.

The document brings lessons learned from the second year of implementation of the cooperation process between the India, Brazil, South Africa Fund (IBSA), the Government of Angola and the United Nations Children's Fund (UNICEF), also in collaboration with the United Nations Office for South-South Cooperation (UNOSSC).
