Planet Earth has been here for over 4.5 billion years, but in just two human generations we have managed to place our only “home” at great risk. Given today’s uncertainties – social, economic, geopolitical, and environmental, it is clear that many lessons from history have not yet been learned and new lessons may prove equally, if not more, difficult to take on board as we head deeper into this century. My new book seeks to raise awareness about major global issues we face, stimulate discussion or debate and find ways forward to ensure planet and people sustainability.
Tsetse flies (genus Glossina) can threaten health and agriculture by transmitting the parasites that cause the potentially fatal diseases of sleeping sickness in humans and nagana in livestock. The fact that only parts of sub-Saharan Africa are infested is attributable to many causes, including the temperature in the area. This raises the possibility that climate change will affect the abundance and distribution of tsetse – the leading questions being how great and how rapid the effects will be. SACEMA is addressing these questions by a combination of field work and simulation modelling.
