Integrated Nitrogen Studies in Africa

Livrables

A website including an interoperable and collaborative platform will be set up for the INSA project in order to better exchange on knowledge work progress and results within the consortium It will also facilitate exchange between WP especially since they are many interconnections between scientific WP 2 to 4 The public site will present the project concept its participating organisations its core objectives PU The website will contain a restricted area for the participating organisations with confidential information CO

First workshop (Côte d'Ivoire)

This workshop will focus on emission and deposition of gaseous compounds in rural and urban environments, and impact on regional climate and atmospheric chemistry. Site visits in FHBU will both deal with modelling and experimental approaches, with a visit of the geophysical Lamto station that is an INDAAF experimental station for atmospheric composition and deposition site since 1995 (Atmospheric measurements: aerosol concentrations (dust, carbonaceous), gases (GHG and reactive), rain, deposition, meteorology) and an AERONET site (ACTRIS FR components), representative of the wet savanna ecosystem. The new supercomputing facilities at Bingerville (supported by FHBU and Bull France) will also be visited.

Mid-term meeting

A meeting will be organized in Europe to ensure the good progress of the research activities and of the implementation of the project. It will include the steering committee and the project management team

Initial Data Management Plan

A Data Management Plan will be established at the beginning of the project

Training manual for implementing NANI approaches and methods for assessing N fluxes via hydrological and gaseous pathways

In close cooperation with WP2 N budgets for selected watersheds eg Nile Zambezi and the entire continent using the net anthropogenic nitrogen input NANI approach will be developed
