Over the last decades, both migration and remittance flows have not only shown an ever-going increase but have also revealed to be a potential source of development in Africa. This chapter provides insights on how easing migration and circularity may stimulate the development of business and scientific networks among migrants and non-migrants. The authors employed secondary sources including administrative reports from public and private bodies as well as collected primary data based on qualitative evidence from 15 return migrants. More precisely, the chapter shows that experiences with corruption and consequences of non-payment in irregular channels have serious consequences for the short-, medium-, and long-term physical and mental health of male and female migrants. The chapter highlights how young people suffer from degraded air and water quality as urban cities buckle under the pressure of an increased population without the adequate waste and chemical management systems along their life-cycle. .
