The history of past civilisations in southern Africa from AD 700 to AD 1450 has engendered unresolved debates on the social complexities and ultimate decline of these powerful states. The purpose of this paper is to examine the history of the Mapungubwe and Great Zimbabwe state systems in southern Africa through an environmental perspective by taking into consideration human responses to persistent droughts and dry spells. The theories underpinning this study are derived from contemporary societal responses to similar environmental hardships in the Bikita and Chivi districts of southern Zimbabwe. Using rainfall data, and interviews with chiefs, villagers, farmers and experts, this study notes that the occurrence of droughts and dry-spell experiences interfere with sociopolitical organisation. The concepts of sustainability, resilience and transformation are used to explain what could have transpired in societies in southern Africa in the second millennium AD in the face of persistent droughts and dry spells.

Relying on complex interdependence as a theoretical approach, this paper investigates the hypothetical damage that the U.S. withdrawal from the Paris Agreement could represent for Africa in terms of climate finance. In June 2017, President Donald Trump publicly declared the U.S. intention to withdraw from further participating in the multilateral Paris Agreement. To keen followers and analysts of the U.S. climate policy beyond its borders, such unilateral action was never a surprise. Rather, it is nostalgic of the experience of the Kyoto Protocol, particularly how more or less similar move unduly prolonged the global climate negotiations up till late 2015 when the Paris Agreement came about. Although the Paris Agreement is remarkable as it represents the first states-wide climate deal, it however left a number of issues unresolved. Notable among which is climate finance which has remained the most contentious and of critical concern to developing countries, particularly in Africa. Pitted against the fact that Africa contributes less to climate change and, ironically, the hardest-hit by the phenomenon, the U.S. withdrawal from the Paris Agreement aggravates concerns around climate finance and, indeed, portends additional burdens for a continent that is still struggling to cope with the untoward fallout of climate change.
