Building on earlier experiences such as LEAP-Agri, Belmont Forum and JPI FACCE, the project will implement a range of joint activities, contributing to the creation of a strong and effective trans-national, European-African-Latin America and the Caribbean research and innovation network and the better coordination and synergising of national, international and EU research programmes relevant to food security under climate change evolution.The joint call will focus on regional food systems within a global perspective and addressing:- Assessing climate change-related risks for food value chains, including impacts on prices, international trade and food security, and resulting changes in consumer behaviours. The three dimensions of sustainability will be adressed: social-cultural, economic, and environmental (including climate change mitigation);- Improving resilience and reducing volatility in agri-food production and food markets to sustainably improve food security in the context of climatic variation;- Reducing food losses under climate change including through novel approaches to valorise side streams and reduce food waste.The first pillar of the proposal relates to the preparation and implementation of a joint call for proposals for collaborative research and innovation projects, funded by European, African and South American national research funding agencies, with additional support from the European Commission. In addition, the call will be co-funded by some Belmont Forum members. These countries does not want to participate to the EU project but will be surely, as Belmont forum, member participating to the call, funding their national teams without any top up from the European Commission. The projects selected through the call will focus on achieving goals of mutual benefit for Member States, Associated Countries and Africa and South America countries, based on a balanced and cooperative approach.
