Long-term atmospheric inorganic nitrogen deposition in West African savanna

• Nitrogen critical loads are poorly assessed in Africa.

• The International Network to study Deposition and Atmospheric chemistry in Africa (INDAAF) project,
  operational since 1995, has provided the first consistent in situ measurements of wet and dry N deposition fluxes in rural Sub-Saharan Africa ecosystems.

• Eutrophication

• Lack of available long term measurements in Africa
