This policy brief describes work carried out by CIAT in partnership with the University of the West Indies (UWI), which used climate predictions and crop suitability models to assess the likely impact of climate change on crops grown in Trinidad & Tobago. Key policy recommendations are provided.

Throughout Africa the importance of land use issues in relation to tsetse control planning has been emphasized consistently in the tsetse literature. Because of inappropriate land use, concerns for the environment in tsetse-freed areas have been expressed frequently. This debate is very relevant to Zimbabwe, where extensive tsetse control operations in recent years have confined the remaining area of tsetse infestation to parts of the Zambezi valley, a semi-arid region of the country with a fragile eco-system and limited agricultural potential.

This audiotutorial unit (cassette, printed script, 76 color slides, study guide, self-evaluation test), prepared by the Communications Support Unit at CIAT, is available for use with a manually or automatically synchronized slide projector/cassette tape reccorder. Each unit is a vailabIe from the Distribution Office at a cost of US$ 50; photocopies of the study guide alone can be obtained from the Cassava Information Center. The objective of this unit is to present some of the results of research conducted by the physiology Section of CIATs Cassava Program.
