Leistungen

Websites, patent fillings, videos etc. (1)

Project branding and website

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

Other (3)

Second workshop (Kenya)

The second workshop in Kenya will focus on site measurement technique deployment, quality control of observations and data-handling, process samples related to hydrological and gaseous fluxes of nitrogen. ILRI analytical lab and the Mazingira Centre will be visited. Participants will be informed on N flux measurements representative of different agricultural management and on technical analytical protocols for N chemistry in water for hydrological losses and gaseous losses via N2O. It will benefit from the ILRI campus in Nairobi where accommodations is available. Lectures will also include NANI approach procedure. Training manual for implementing NANI will be made available on the collaborative interoperable platform

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

Open Research Data Pilot (2)

Initial Data Management Plan

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

Final Data Management Plan

DMP will detail: (1) Data set reference and name, (2) Data set description, (3) Standards and metadata, (4) Data sharing, (5) Archiving and preservation (including storage and backup). This DMP will ensure that data follow the FAIR principles in order to improve and maximise reuse of research data beyond the original purpose of the project for which it was collected.

Documents, reports (3)

Standard Operating Procedure (SOP) related to technical skills

Standard Operating Procedures (SOP), including guidelines on site selection (representativeness), on adequate instrumentation, on collection procedures, on analytical protocols, on quality assurance (QA) and quality control (QC) will be developed.

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

Policy brief, guidelines for adaptation and mitigation on nitrogen use

Stakeholders have been identified to ensure that findings are involved in the development of holistic solutions for good N management. The network of those stakeholders will assess the scientific evidence, identify barriers to implementation of the recommended solutions, and options to overcome them. The network will inform the design of decision support tools, and decision-making tree based on technical and financial consideration. It will also be an opportunity to seek for commitment of the various stakeholders and policy makers to address the challenges and issues based on their ability and professional responsibilities. A policy brief will summarize these statements.
