The population of the world is becoming increasingly urbanised due to a combination of natural population growth and rural–urban migration. This will pose major challenges to feed the future population and meet the Sustainable Development Goals. Meeting these complex challenges requires an integrated approach. The transition support system (TSS) approach integrates decision support tools and stakeholder analyses for these complex issues. This study has focused attention on the application of decision support tools of the TSS approach that visualises the urgency of future food security as a proof of concept. To this end, the future food security of the city of Accra, the capital of Ghana, has been taken as a case study. The use of Global-Detector and its maps illustrated a quick way to downscale data and projections from MAGNET (Modular Applied GeNeral Equilibrium Tool) and perform spatial analyses without the burden of acquiring additional data. Downscaling of macroeconomic results of future projections provides insights into future urban food security. Giventhese insights, stakeholders might urge policy or interventions. The results of the exercise are largely determined by the availability of data and maps; in particular, the more detailed information is available, the more accurate the results of our exercise will be.
A perspective on water quality in connected systems: modelling feedback between upstream and downstream transport and local ecological processes
Teurlincx, Sven ; Wijk, Dianneke van; Mooij, Wolf M. ; Kuiper, Jan J. ; Huttunen, Inese ; Brederveld, Robert J. ; Chang, Manqi ; Janse, Jan H. ; Woodward, Ben ; Hu, Fenjuan ; Janssen, Annette B.G. - \ 2019

Food production for a growing world population relies on application of fertilisers and pesticides on agricultural lands. However, these substances threaten surface water quality and thereby endanger valued ecosystem services such as drinking water supply, food production and recreational water use. Such deleterious effects do not merely arise on the local scale, but also on the regional scale through transport of substances as well as energy and biota across the catchment. Here we argue that aquatic ecosystem models can provide a process-based understanding of how these transports by water and organisms as vectors affect – and are affected by – ecosystem state and functioning in networks of connected lakes. Such a catchment scale approach is key to setting critical limits for the release of substances by agricultural practices and other human pressures on aquatic ecosystems. Thereby, water and food production and the trade-offs between them may be managed more sustainably.

Agricultural intensification - Baseline projections - CGE model - Diet diversity - Food security - Land substitution - Nutrition

Nigeria is one of the most dynamic economies in Africa. Strong GDP and population growth coupled with urbanization trends place tremendous pressures on natural resources and the food systems that are dependent on them. Understanding the impact of these "mega trends" is important to identify key leverage points for navigating towards improved nutrition and food security in Nigeria. This paper contributes to the Foresight Project of the Food Systems for Healthier Diets which aims to analyse how the food system in Nigeria is expected to transform in the next decades, and to identify the leverage points for making sure that the transformation contributes to balanced consumer diets. For the food systems foresight, a well-established global economy-wide model, MAGNET, is applied that enables to capture the interlinkages among different food industry players in one consistent framework. By linking MAGNET to the GENUS nutritional database, it is further possible to relate the developments occurring on a macro-level with detailed macro and micronutrient consumption. Model projections suggest that a process of intensification of agriculture in combination with land substitution appears critical for the evolution of food and nutrition security, and for shifts towards healthy diets for the population. Intensification results in greater diversity of the production systems, which in turn cascades into positive effects on the diversity in the food supply and better food security outcomes.

crop biotechnology - gene editing - genetically modified crops - international harmonization - novel plant breeding techniques - regulation - risk assessment - safety assessment

Gene editing and other innovative plant breeding techniques are transforming the field of crop biotechnology. Divergent national regulatory regimes worldwide apply to crops bred with these techniques. A plea is made for international harmonization of the premarket assessment of their safety. Such harmonization has previously been achieved for genetically modified (GM) crops.

Towards restoring urban waters : understanding the main pressures

Water bodies in the urban landscape are omnipresent, with many being small, lentic waters such as ponds and lakes. Because of high anthropogenic forcing, these systems have poor water quality, with large consequences for the provisioning of ecosystem services. Understanding of the main pressures on urban water quality is key to successful management. We identify six pressures that we hypothesize to have strong links to anthropogenic forcing including: eutrophication, aquatic invasive species, altered hydrology, altered habitat structure, climate change, and micropollutants. We discuss how these pressures may affect water quality and ecological functioning of urban waters. We describe how these pressures may interact, posing challengers for water management. We identify steps that need to be taken towards sustainable restoration, recognizing the challenges that potentially interacting pressures pose to water managers.

Nitrogen fixation does not axiomatically lead to phosphorus limitation in aquatic ecosystems

eutrophication - nitrogen fixation - R*

A long-standing debate in ecology deals with the role of nitrogen and phosphorus in management and restoration of aquatic ecosystems. It has been argued that nutrient reduction strategies to combat blooms of phytoplankton or floating plants should solely focus on phosphorus (P). The underlying argument is that reducing nitrogen (N) inputs is ineffective because N2-fixing species will compensate for N deficits, thus perpetuating P limitation of primary production. A mechanistic understanding of this principle is, however, incomplete. Here, we use resource competition theory, a complex dynamic ecosystem model and a 32-year field data set on eutrophic, floating-plant dominated ecosystems to show that the growth of non-N2-fixing species can become N limited under high P and low N inputs, even in the presence of N2 fixing species. N2-fixers typically require higher P concentrations than non-N2-fixers to persist. Hence, the N2 fixers cannot deplete the P concentration enough for the non-N2-fixing community to become P limited because they would be outcompeted. These findings provide a testable mechanistic basis for the need to consider the reduction of both N and P inputs to most effectively restore nutrient over-enriched aquatic ecosystems.

Food system assessment - Food systems - Interdisciplinarity - Metrics - Participatory approach - SUSFANS - Sustainable food and nutrition security

Steering the EU food system towards a sustainability transformation requires a vast and actionable knowledge base available to a range of public and private actors. Few have captured this complexity by assessing food systems from a multi-dimensional and multi-level perspective, which would include (1) nutrition and diet, environmental and economic outcomes together with social equity dimensions and (2) system interactions across country, EU and global scales. This paper addresses this gap in food systems research and science communication by providing an integrated analytical approach and new ways to communicate this complexity outside science. Based on a transdisciplinary science approach with continuous stakeholder input, the EU Horizon2020 project 'Metrics, Models and Foresight for European SUStainable Food And Nutrition Security' (SUSFANS) developed a five-step process: Creating a participatory space; designing a conceptual framework of the EU food system; developing food system performance metrics; designing a modelling toolbox and developing a visualization tool. The Sustainable Food and Nutrition-Visualizer, designed to communicate complex policy change-impacts and trade-off questions, enables an informed debate about trade-offs associated with options for change among food system actors as well as in the policy making arena. The discussion highlights points for further research related to indicator development, reach of assessment models, participatory processes and obstacles in science communication.

EU sustainable food and nutrition security is no sure-fire success. The future of
the agro-food system is uncertain and subject to different macro-level trends.
Previous analysis revealed the role of food system drivers creating challenges and
opportunities for dietary and environmental improvements under certain future
constellations. However, these challenges and opportunities need to be addressed by policies to allow for actual improvements in the sustainability
performance of EU food systems, for people, planet and profit. In this deliverable,
an assessment and pre-test of potential policy measures is carried out. The policy
analyses are contrasted to a ‘business-as-usual’ baseline scenario with current
trends of food system drivers. We apply the SUSFANS modelling toolbox in order
to test relevant policy measures in four distinct aqua-agro-food policy sectors.
Regarding health and nutrition of the EU population, we provide a ranking of
potential dietary policies and interventions based on their effectiveness,
implementation costs and restrictiveness for consumers and producers. Based on
this overview, options for health and nutrition policy are designed containing a
mixture of different policy instruments. These apply – in line with the allocation
of policy responsibilities in the EU - at the level of individual member states and
not at the realms of an EU policy. In the context of the Common AgriculturalPolicy (CAP), we assess the impact of a livestock density restriction on EU Agricultural areas. Results indicate a reduction of soil nutrient surpluses (-9 to -13%) and of greenhouse gas emissions (-9%) at EU average and considerably stronger in the livestock density and over-fertilization hotspots. Trade openness restricts the impact on food consumption and dietary change of EU consumers. Three Common Fisheries Policies (CFP) are tested with the newly developed fish modules of GLOBIOM and CAPRI: Directing capture in EU waters to levels that keep fish stocks at the maximum sustainable yield (MSY), or at the maximum economic yield (MEY), and the implementation of national aquaculture growth plans composed by EU member states. Our results show limited policy impacts due to the rlatively small size of the EU fish producing sector with some trade but
limited consumption changes. Finally, different storage policies are tested with the new short-term volatility module of GLOBIOM. The scenarios reveal that storage availability and intervention prices reduce price volatility caused by yield shocks. The assessments illustrate that individual, yet unaligned policy measures can already contribute significantly to reaching sustainable food and nutrition
security. On the way to the final foresight assessment extensions are require regarding a) metrics quantifiability, b) the harmonization of metrics computation
approaches, and c) smaller model improvements
