Green Shield Africa Nexus (GSAN) is a research, consultancy and advisory company working where security, climate action and livelihoods meet.
We believe the police station, the barracks and the border post can lead Africa's green transition. Greened, they cut costs and emissions. Opened to their communities, they build trust, restore land and give young people a path into green jobs.
Anchored by our partnership with the Ghana Police Service, we work with five partner ministries, their agencies, development partners and the private sector to design, evidence and deliver that model, in Ghana and across Africa.
Supporting safer communities, trusted policing and action against environmental crime.
Building climate-smart skills, agribusiness opportunities and resilient livelihoods.
Supporting climate resilience, land restoration and responsible environmental management.
Using research, data and digital tools to make decisions and results evidence-based.
Partner with GSAN to connect security, climate action and livelihoods through research, advisory services, training and measurable programmes.
The results we commit to by 2029.
