Climate Change
DACCIWA
The challenge
Massive economic and population growth
and urbanisation are expected to lead to
a tripling of anthropogenic emissions in
southern West Africa (SWA) between
2000 and 2030, the impacts of which on
human health, ecosystems, food security
and the regional climate are largely
unknown.
An assessment of these impacts is
complicated by (a) a superposition with
effects of global climate change, (b) the
strong dependence of SWA on the
sensitive West African monsoon,
(c) incomplete scientific understanding of
interactions between emissions, clouds,
radiation, precipitation and regional
circulations, and (d) by a lack of
observations to advance our
understanding and improve predictions.
Project Objectives
DACCIWA will quantify the influence of
anthropogenic and natural emissions on
the atmospheric composition over South
West Africa and assess their impact on
human and ecosystem health and
agricultural productivity. It will quantify
the coupling between aerosols and clouds
and identify controls on the formation
and persistence of low-level clouds.
Further it will identify meteorological
controls on precipitation, focusing the
transition from stratus to convective
clouds and the forcing from weather
systems. DACCIWA will quantify the two
way cloud and aerosol impacts on the
radiation and energy budgets from the
cloud scale to the scale of the West
African monsoon circulation. State-of-the-
