Mali

The Gourma mesoscale site (Mali) is part of the mesoscale observation network of the AMMA-CATCH observatory. Various instruments have been deployed there since 1984, in order to monitor the water cycle and vegetation dynamics. Their distribution is shown on the map below [observation period : 2004-2011]. An interactive map of the instruments at different scales is available on the AMMA-CATCH database portal.

Its characteristics are as follows :

The Gourma mesoscale site (30 000 km²) is subject to a Sahelian to North Sahelian climate, with a short rainy season of about 3 months (annual rainfall : 200-400 mm). The average annual temperature is 30.2°C in Hombori. The dominant vegetation formation is a shrubby savannah on sandy dunes that alternate with erosion surfaces with strong runoff that converge towards ponds (endoreism). The population density is low, less than 7 inhabitants per km², and the main socio-economic activity is pastoralism. Millet cultivation is only practiced in the southern part of the mesoscale site.

Since 2012 the monitoring of this site is on standby for security reasons.
In 2021, only rainfall and vegetation measurements will continue in the vicinity of the town of Hombori, in what used to be the AMMA-CATCH super-site. The observations are conditional on the evolution of the security situation.
