The DIZA programme is the result of a request from the Chadian State, through the Ministry of Economy and Development Planning, to intervene on the dynamics of host populations / refugee populations, returnees and displaced persons to which the European Union has responded positively. The DIZA targets vulnerable people, namely indigenous people, refugees, displaced persons and returnees in various regions of Chad. The programme approach is part of the humanitarian-development nexus, i.e. the DIZA thus combines humanitarian and development activities.
Ranked 186 out of 188 countries on its Human Development Index, Chad is the 4th largest country in the world in terms of the proportion of refugees in relation to its indigenous population. Indeed, for more than a decade, conflicts in the Central African Republic, Sudan (Darfur) and more recently in Nigeria have forced 380,000 people to flee their countries to Chad, mainly in the eastern and southern regions of the country.
The level of poverty, linked to unemployment and lack of access to economic, social and environmental resources and basic services (schools, water, hygiene and sanitation infrastructure, functional health centres, etc.) and limited natural resources, weakens the situation of host populations and refugees.
