Kentsel Gıda Planlaması için Çıkarımlar: Gıda'nın Kent-Bölgesi'ni Tanımlamak (Inferences for Urban Food Planning: Defining City-Region of Food)
2023Ayşegül YARIŞ, Emel Karakaya Ayalp · Zenodo (CERN European Organization for Nuclear Research) · Global
The current agri-food system is undergoing an unsustainable transition, with Urban Food Planning emerging as a holistic approach for sustainable transition. This paper explains and translates the "City-Region Food System (CRFS) Toolkit," developed in partnership with FAO, RUAF, and participating cities. It examines the toolkit's roadmap and approach for building more sustainable and resilient urban food systems through two case studies in West Africa. The research concluded that the CRFS Toolkit defines limited tools for building sustainable urban food systems and excludes the relationship with spatial disciplines.

2022Angelica Mendoza Beltrán, Kelzy Jepsen, Martí Rufí-Salís, Sergi Ventura, Cristina Madrid‐López, Gara Villalba · The Science of The Total Environment · Spain (Barcelona)
This study mapped N2O emissions from peri-urban agriculture in the Metropolitan Area of Barcelona (AMB), Spain. Researchers spatially distributed factors like crop type, fertilizer use, and irrigation, creating N2O emission maps using crop-specific and Tier 1 IPCC emission factors (EFs). The study found that Tier 1 IPCC EFs estimated 15% more emissions (7718 kg N2O-N year−1) than crop-specific EFs (6533 kg N2O-N year−1) for the entire AMB, indicating higher emissions for rainfed crops with Tier 1 EFs and for irrigated horticultural crops with crop-specific EFs. The mapping helps evaluate spatial variability of key factors but carries uncertainties due to downscaling regional data.
