This chapter reviews case studies as qualitative evidence of social and economic growth. Three international case studies are examined: from a developed, Transitional, and Developing Country, and two from Africa. The goal is to show that effective rural development can sustainably improve rural lives and encourage urban-to-rural migration. International case studies include Zhejiang Rural Development in China, illustrating land circulation fostering agricultural, industrial growth, and migration; Boekel, Netherlands, re-using farm buildings for commercial purposes; and Petrolina-Juazeiro in Brazil, with irrigation projects transforming the economy and reducing rural poverty. African case studies include Nigeria’s community-led Development project in Ahiazu Mbaise and South Africa’s Rural Development Programme and Youth Service Corps, aimed at economic growth and sustainable communities.
