“…The Global Metropolitan Detector tool is an extension of the Global-Detector tool, a knowledge-based Geographic Information System (GIS) in R that aims to detect the worldwide potential for production, demand and market strategies regarding agricultural commodities [18]. It does so by arithmetically combining and weighing public available worldwide GIS data on factors affecting the production and consumption of agricultural commodities.…”

Due to the combined effect of climate change, expected population growth and increased concentration of population in cities and towns, food insecurity in urban areas is becoming of increasing concern and is regarded as one of the most prominent development challenges for the 21st century. Cities differ with respect to their specific food security risks and opportunities of local food supply to meet the increasing demand for food. The tool "Global Metropolitan Detector" has been developed to compare cities of the world based on different dimensions of food security, particularly availability, accessibility, and affordability of food, risk of floods and climate change, and healthy diets. Worldwide publicly available datasets, e.g. from FAOSTAT, EarthStat and WorldClim, are used. These are separately converted (aggregated/disaggregated) to a homogenous 5 arc-minute grid and combined in the tool to calculate (by weighted average) and compare the demand and local supply of food, including the required area of land to meet the city-specific consumption needs (measured in "Food Metres"). The purpose is to benchmark 850 cities based on several aspects related to food security. The resulting benchmark of cities and their indicator values can be visualised in maps showing their position with respect to food security in general, or investigate particular aspects in more detail, e.g. cities having low/high flood risks or cities that are better able to meet the demand of (fresh) vegetables and fruit from local producers. The maps can support policymakers to identify causes and locations of food insecurity, and the indicative results-based on limited available worldwide data-can serve as an inducement for further investigation with more detailed data from cities.

“…Global Detector is een analysemethode om met behulp van ruimtelijke gegevens de meest geschikte locaties te identificeren voor bepaald landgebruik (Hennen et al, 2017;Hennen et al, 2018). Meestal wordt dit gebruikt om op nationale of internationale schaal te kijken naar bijvoorbeeld de beste regio voor een bepaalde vorm van voedselproductie op een schaal van 10x10 kilometer.…”

Marijke Kuiper, Lindsay Shutes, 2019. Transition support system approach for urban food security in the future; The case of Ghana. Wageningen, Wageningen Economic Research, Report 2019-057a. 44 pp.; 25 fig.; 7 tab.; 22 ref.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. Given these 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.
