Delta State, Nigeria


Initiated in 2013 under the driving force of the Government of Delta State, the Delta State Territorial Approach to Climate Change Programme (TACC) aims to make Delta State one of West Africa’s leading regions in climate change mitigation and adaptation. With support from UNDP, the Delta State Ministry of Environment’s Climate Change Department and various technical partners, this programme has led to the implementation of a number of community-level projects. A second programme, the Green Economy Initiative, looked at ways to institutionalize green growth and project development through setting up a dedicated agency. Through this initiative, preparatory studies were also carried out for different project types. This early work caught the eye of the Niger Delta Development Commission (NDDC), with whom R20 has discussed a potential partnership for implementing green infrastructure projects.


In January 2013, R20 signed a contract with the Government of Delta State to act as the International Consultant of the TACC programme and provide technical as well as strategic assistance for a “future beyond oil”.
In collaboration with the Ministry of Environment and the Delta State Climate Change Team, R20 produced the Delta State Integrated Territorial Climate Plan (ITCP), which includes a biophysical and socio-economic assessment of the Nexus of Environmental Degradation and Climate Change in Delta State, and led to the identification and implementation of various “quick-win” community-level projects.

Implementation of an integrated solar-powered project at the Primary Health Center in Oko-Amokan Community, which provides hot, clean water to the entire clinic and enables medical instruments to be sterilized. The system consists of a solar-powered water borehole pumping water into a mini water treatment tank, that is then heated using solar power.

Installation of a household biogas digester at the Delta State Government Guesthouse in Asaba. The biogas digester, developed by R20’s technical partner, Biotec Development Network, consists of a 10 cubic meter underground tank that generates methane gas for cooking by anaerobically digesting food scraps.

Biotec Development Network is still active building biogas digesters and recently installed one in Abuja as part of a national development project.

In partnership with Triple Quest, The Foundation for Partnership Initiatives in the Niger Delta (PIND), Life and Peace Development Organization (LAPDO), and the Delta State Ministry of Environment’s Climate Change Department, R20 deployed biosand water filters to 52 selected households in the Akugbene Community. Using a carbon-neutral technology that is appropriate for the region and easy to set up (30min), this project helped increase access to clean drinking water and reduce instances of water-borne illnesses.

Inspired by the early results of the TACC programme, the Government of Delta State and UNOPS mandated R20 to explore the feasibility of setting up a cross-cutting body, based after the model of the California Environmental Protection Agency, dedicated to expanding sustainable economic development through the initiation, implementation and coordination of green economy policies and projects.  The concept and structure of a Delta State Green Economy Commission (DSGEC) was created in March 2014. As a follow-up to that work, R20 and its technical partners, with insight from the relevant ministries, prepared studies for

1) Institutional solar thermal water heating in Delta State 

2) Solar PV projects in Delta State 

3) Solid Waste and Recycling for the City of Asaba


Inspired by the work done for the TACC and Green Economy Initiative, R20, in partnership with Next Possibilities, collaborated closely with the Niger Delta Development Commission (NDDC) to elaborate green economy programmes in the 9 oil producing states of Nigeria. R20 is in discussion with the NDDC to explore a partnership for implementing green infrastructure projects.
