Lay Summary (German)

Lead
Die Welt steht vor der grossen Herausforderung, eine wachsende Bevölkerung bei gleichbleibenden oder gar schwindenden Landreserven und steigenden Umweltbelastungen zu ernähren. Das Team von Nina Buchmann untersucht im Rahmen eines weltweiten Forschungsverbundes, wie die lokale Lebensmittelnachfrage auf verschiedenen Kontinenten aufgrund der zur Verfügung stehenden natürlichen und sozialökonomischen Ressourcen gedeckt werden kann.
Lay summary
Die Ernährungssicherheit auf begrenztem Land sicherzustellen, stellt eine der grossen globalen Herausforderungen von heute und der Zukunft dar. Der Forschungsverbund untersucht dazu die vielfältigen Wechselwirkungen, die zwischen Landnutzung, Landnutzungsänderungen und Ernährungssicherheit existieren. Hochauflösende räumliche Modelle sowie Datenbanken zu Böden, Landnutzung, Ackerbau und Viehzucht liefern die Basis für den die Forschungsteams aus sechs Ländern. Dabei quantifizieren sie die Nachfrage an Lebensmitteln auf Länderebene mithilfe eines globalen Modells (FEEDME) und verschiedener Statistiken der Ernährungs- und Landwirtschaftsorganisation der vereinten Nationen (FAO). Ein weiteres Modell, das die ökonomischen und soziopolitischen Rahmenbedingungen der Lebensmittelproduktion und des internationalen Handels berücksichtigt, simuliert die Deckung der Nachfrage. Nach Überprüfung der Simulationen mit aktuellen Datensätzen werden die Forschungsteam mithilfe der Modelle verschiedene Szenarien überprüfen – sowohl im Hinblick auf das Angebot von Lebensmitteln als auch die Nachfrage nach ihnen. Änderungen in Produktionssystemen, in der Verteilung von Lebensmitteln und im Handel werden ebenso untersucht wie verändertes Essverhalten und Verringerung von Abfall und Verlusten entlang von Wertschöpfungsketten. Mittels regionaler Analysen in Südasien, in Afrika südlich der Sahara und in Südamerika werden einzelne Wechselwirkungen detaillierter betrachtet. Verschiedene internationale Stakeholder unterstützen die Arbeiten des Forschungsverbundes.

Lay Summary (French)

Lead
Le monde fait face au défi de nourrir une population croissante à partir de surfaces agricoles constantes, voire en diminution, et soumises à une pollution toujours en augmentation. L'équipe de Nina Buchmann analyse, dans le cadre d'un projet d'envergure internationale, comment la demande alimentaire locale peut être satisfaite sur les différents continents en se basant sur les ressources naturelles et socio-économiques à disposition.
Lay summary

Assurer la sécurité alimentaire sur un territoire délimité représente l’un des plus grands défis mondiaux actuel et futur. Les chercheurs de ce projet de coopération s'intéressent aux diverses interactions existantes entre la gestion du sol, les changements dans cette gestion et la sécurité alimentaire. L'utilisation de modèles à haute résolution et de bases de données sur les sols, l'utilisation des sols, l'agriculture et l'élevage est à la base de ce projet mené par des équipes de recherche issues de six pays. La demande en nourriture au niveau national est quantifiée grâce à un modèle mondial (FEEDME) alimenté par diverses statistiques de l’Organisation des Nations Unies pour l'alimentation et l’agriculture (FAO).

Un autre modèle prenant en compte les conditions-cadres économiques et sociopolitiques de la production alimentaire et du commerce international simule la satisfaction de la demande. Après validation des simulations avec des jeux de données actuels, ces modèles permettront de tester différents scénarios concernant l'offre et la demande en denrées alimentaires. Différents paramètres sont examinés : modifications des systèmes de production, commerciales et des modes de  distribution alimentaire ; changement du comportement alimentaire ; ou encore diminution des pertes et des déchets le long de la chaîne de valorisation. Des interactions spécifiques sont analysées plus en détails au niveau régional en Asie du Sud, Afrique subsaharienne et en Amérique du Sud. Différentes parties prenantes à l’échelle internationale soutiennent les travaux de ce projet de coopération.

Lay Summary (English)

Lead
The world is facing the great challenge of feeding a growing world population on an unchanged or even decreasing amount of land reserves and under increasing environmental effects. Nina Buchmann’s team together with other research teams worldwide is examining how local food demand on different continents can be satisfied given the available natural and socio-economic resources.
Lay summary

Delivering food security on limited land is one of the great global challenges today and in the future. The project examines the many feedback interactions that exist between land use, land use change and food security. Together with research groups from six countries worldwide, high resolution spatial models as well as data bases of soils, land use, crops and livestock will be used.

The team of Nina Buchmann quantifies food demand on a national level by means of a global model (FEEDME) and various statistics of the Food and Agriculture Organization of the United Nations (FAO). A further model takes into account the economic and socio-political conditions for food production and international trade simulates how food demand can be satisfied. After checking the simulations against current data, the research team will use the models to test various scenarios – regarding supply as well as demand for food. Changes in production systems, food distribution and trade will be examined, as will changing diets and waste and loss reduction along the value chains. By means of regional analyses in South Asia, sub-Saharan Africa and South America, individual feedback interactions will be investigated in more detail. Various international stakeholders are supporting the work of the research teams.

Abstract

We will examine the challenge of delivering food security now and in the future on limited area, which will entail examining feedback interactions between land use change and food security dynamics. We will use the high resolution, spatially disaggregated global models and databases of soils, land-use, crops and livestock, developed by consortium partners as the basis for the analysis. We will use the global FEEDME model, informed by FAO statistics and nutritional demand, to derive country level dietary demands for food products. We will develop and use a country-level agent based model, that includes economic and sociopolitical constraints on food production and trade between countries, to satisfy the demand for food either locally, or through trade (constrained by international trade statistics), given the soil, crop and livestock resources available. Performance of the modeling system will be tested against current statistics on food (in)security, and spatial data on hotspots of land use change. The system will be considered adequate if it is able to replicate the current status. Once evaluated, the modeling system will be used to examine a range of scenarios including a) production side measures to improve food security, through: i) sustainable intensification (closing the yield gap; improving livestock), ii) redistribution and trade, and b) demand side measures through i) changing diets, ii) reduced waste (pre- and post-harvest). The feedback interactions between these drivers of change and land use, and the feedback to food supply will be examined globally. Additional regional analysis will examine impacts on food security, land use change and selected ecosystem services in three regions that are key for food security and land use change: South Asia, sub-Saharan Africa and South America. We anticipate that this work will yield high impact papers and information critical to policy makers, industry and other stakeholders. The project will contribute to Future Earth, CCAFS, the Global Land Project and the Programme for Ecosystem Change and Society.
