Project title
Agroclimatic analysis for viticultural terroir studies

Project leaders
Bonnardot, V M F
Carey, V A

Institution
University of Stellenbosch

Project description
Terroir is a complex concept that requires multidisciplinary study. An integral component of terroir studies is climate, and a climatologist thus forms an integral part of a terroir research team. There are no expert agro climatologists, with a viticulture specialisation, currently in South Africa. Dr Bonnardot, an agro climatologist, who has specialised in viticultural applications in South Africa since 1996, returned to France in 2004.

The aim of this project will be to obtain the services of Dr Bonnardot to provide expert climatological support to terroir projects registered with Winetech.
