East Africa is characterised by extreme social and environmental contrasts that has undergone transformative changes over the past 300,000 years - the era of modern humans. People have left increasingly deep and pervasive footprints across the region, resulting in the anthropogenically crafted landscape of the present. The book shows how understanding contemporary issues, such as climate change, biodiversity loss, conservation, agricultural development, and achieving the sustainable development agenda, all require an appreciation of the past. The volume explore these interactions from the origins of human species with a particular focus on the last 500 years the Anthropocene. As trade, particularly of ivory, maize, and munitions, expanded with the Asia, Europe and the Americas this shaped many of the current issues in East Africa's society, economy, and environment. These trade links paved the way for the colonial era that started at an atypical moment in East African environmental history. The colonial impacts on society, ecosystems, Protected Areas, biodiversity conservation, and the ensuing legacy through the independent states of Kenya, Tanzania and Uganda are explored. Given this rich, diverse, and connected past, what the future will be like for East African societies, ecosystems, and landscapes under climate change, high population growth, and rapid development? Rob Marchant is Professor of Tropical of Ecology at the University of York, UK. Much of his research is focused on East Africa, where over the past thirty years of working in Uganda, Kenya, and Tanzania he has developed close collaborations with the numerous University, NGO, UN and Governmental institutions that, alongside multiple conversations with individuals, have profoundly influenced and shaped the perspectives presented here. The interplay between the climate, ecosystems, cultures, livelihoods, and land uses are explore to document how the massive challenges facing the region have been created, are being addressed and future opportunities maximized.
