MACS Collaboration Initiative on Food Losses & Food Wastes

Reducing food losses & food wastes (FLW) is a key global challenge to ensure sufficient and healthy food for the future and to use available resources – arable land, water, nutrients, energy, labour – as efficiently as possible.

Background & Objective

Radical reduction of food losses and waste (FLW) is a crucial issue to ensure global food security and to use the available resources in the best manner possible. Not for nothing United Nations identified FLW reduction as Goal 12.3 of Sustainable Development Goals.

Hence at MACS Meeting 2015 in Izmir (Turkey) the G20 States decided to place emphasis on FLW. Germany was charged with developing relevant activities. First step was the establishment of an appropriate web portal with information about current research activities, latest innovations and available scientific expertise.

But only collecting and documenting information isn’t enough. In fact G20 States should unite their strong potentials and make significant contribution to real progress. So as next step a joint MACS initiative is scheduled pooling promising research findings, innovative technological and logistical solutions, successful campaigns etc. concerning FLW reduction. Goal is to organize "touchable" progress.

MACS Workshops for joint FLW action

Successful MACS driven activities concerning FLW reduction require both a coherent strategy and its well-considered implementation. As announced at MACS Meeting 2016 in Xi’an (China), this perennial process started with a kick-off workshop of interested MACS partners in June 2017 in Berlin.

One aim of our activities is to organise an international FLW workshop annually in cooperation with that G20 member who holds the present G20 presidency. The corresponding workshop should be dedicated to specific Food Loss and Waste topics relevant for the region and open for various stakeholders.


Thus, the second FLW workshop was organised in November 2018 in Buenos Aires/Argentina. The Argentinian Secretary of Agroindustry, FAO Latin America and the Caribbean, FAO Argentina, Instituto Nacional de Tecnología Agropecuaria (INTA) and Thünen Institute organised the side event “Regional Dialogue on Food Loss and Waste: Latin American solutions and initiatives” that was embedded within the FAO event “Week of Food and Agriculture”.

In plenary and working group sessions several issues of food loss and waste were presented and discussed among the approx. 50 participants from eleven Latin American and Caribbean countries. The participants represented a very good mix of policy decision makers, food producers, NGOs, international associations and researchers.

At the end of the workshop, the “Call to Buenos Aires Action on Food Loss and Waste” was signed by all organisers and by representatives from the Interamerican Development Bank, the Consumer Goods Forum as well as the Global Food Banking Network (english version, spanish version of the call). By signing this Call the participants underlined their strong commitment for future joint cooperation and support of food waste prevention activities in the region.


The next FLW workshop of this series will take place in the South East Asian region in 2019.
