Present-day development issues are complex, enigmatic & a subject of intense academic, institutional, national & international debates. Why some are poor & in a state of incessant turmoil & others are wealthy & stable is still a mystery to be resolved. Development actors are trying to offer the best possible answer & usually such answers are manifested in the form of debates. Currently, the key development issues in developing countries ranges from climate change, human security, conflict, global political economy, issues of governance, the rule of law, health, capital formation, education, equity, gender, natural resources & others. The relationship among & the nexus between some of the issues is not usually apparent & remain the subject of continuous discussion. Based on contemporary literature, this book discusses some of the current key development arenas that include climate change, human security, conflict, global political economy, decentralization, participation, capacity development, food security, good governance & good enough governance which are common to most of the developing countries.
