This paper introduces a series of African and Asian case studies on environ
ment and development. It explores the tension between optimistic and pessim
istic interpretations of environmental maintenance and transformation. It c
ritically examines political ecology and eco-populism before analysing unde
rlying models of governance, social justice and human rights. Key concepts
in understanding the relationship between environment and development are d
iscussed, including security, sustainable livelihoods, coping and entitleme
nts. The paper ends with a discussion of marginality and vulnerability with
particular attention to urban and informal sector environments. Copyright
