For Cape Verde's Ministry of Infrastructure and with financing from the EU's ninth European Development Fund (EDF), STELLA designed with Hydea a system of integrated solid waste management for the six municipalities of the Island of Santiago in Cape Verde. STELLA assessed the quantities of waste generated on the island and the equipment and infrastructure currently used to manage the waste. After identifying the current and future needs of the municipalities, STELLA proposed the creation of an inter-municipal autonomous structure that would collect and treat the waste generated by the six municipalities. This new structure will be in charge of managing three new controlled landfills and over 20 rubbish disposal trucks. STELLA proposed various options to finance the new structure and ensure full-cost recovery (tax on imported packaging and tariffs paid by shops and residents). STELLA also recommended the launch of a public awareness campaign to encourage residents to dispose of their rubbish in the proper containers. Finally, STELLA recommended a new system to safely dispose of medical waste and to study the feasibility of segregating and recycling paper, glass, plastic, and aluminium.

STELLA staff has provided technical assistance to UNIDO and the Governments of Benin, Cameroon, Ghana, Ivory Coast and Nigeria in establishing a programme to reduce industrial discharges and protect the Large Marine Ecosystem of the Gulf of Guinea. Textile, brewing, palm oil, rubber and petroleum are the primary industries of concern. STELLA staff visited seven plants in those industrial sectors as well as laboratories and discussed current industrial pollution prevention and control efforts undertaken by the Governments of Benin, Cameroon, Ghana, Ivory Coast and Nigeria. Based on these visits and meetings, STELLA staff developed an action and monitoring plan to inventory and characterise industrial discharges and train local industrial managers in environmental auditing, wastewater pre-treatment and treatment, sampling and analysis, and clean technologies.

For UNOPS and Madagascar's National Office for the Environment, STELLA staff conducted an inventory of Madagascar's marine and coastal ecosystems (in particular, coral reefs and mangroves) and of their biodiversity, and an environmental assessment of Madagascar's coastal zone. Working closely with local experts, STELLA staff collected information and data on the environmental state of marine and coastal resources. STELLA staff identified the main problems and challenges for the sustainable development and conservation of the coastal zone. We recommended institutional, economic, and regulatory tools to implement an Integrated Coastal Zone Management programme in Madagascar. STELLA staff also identified potential marine protected areas.
