De la gestion des déchets à l’agriculture urbaine : circularités et tensions des filières de matières organiques à Nkayi (République du Congo)
2025Noémie Régeard · L’Espace Politique · Congo
This article explores the circularity of organic matter streams in Nkayi, an intermediate city in Congo, through interviews and observations. The qualitative inquiry reveals the coexistence of institutional household waste streams, supported by a development project, and informal organic matter streams, identified through intra- and peri-urban agricultural practices. These streams are subject to various socio-territorial, political, and economic tensions.

2025Christian Kofi Sarpong, Romanus Dogkubong Dinye, Alex Donbeinaa, Vera Nyarko Amoako · Asian Journal of Agricultural and Horticultural Research · Ghana
This study assessed the role of urban agriculture in Ghanaian cities through a systematic literature review of publications from 2000 to 2024. Urban agriculture was found to significantly contribute to food security, nutrition, and income, and to bolster environmental sustainability. However, challenges such as land tenure insecurity, unsafe irrigation practices, weak institutional support, and limited policy integration persist.

2024Chiara Tornaghi · The Geojournal library · Global
This chapter, based on 15 years of research, discusses key issues hindering urban agriculture from reaching its full potential for human and non-human health. It highlights shortcomings in urban planning policy, specifically the failure to recognize urban agriculture as food production, the invisibility of soil and lack of understanding of living soils, and the disregard for the advisory role of soil care and food production specialists in public land design and soil management. The chapter suggests that agroecological considerations can deepen urban agriculture's ambition in public spaces.

2024Nordregio, Luciane Aguiar Borges, Ana de Jesus · · Global
This report discusses the barriers and drivers of Urban Agriculture (UA) within the framework of the Horizon 2020 project 'SiEUGreen,' across environmental, technological, economic, social/cultural, and regulatory/institutional aspects. Based on insights from five showcases in Norway, Denmark, Turkey, and China, the results suggest that city food provision and UA systems can be designed considering circular economy regenerative cycles. However, key barriers limiting UA uptake include the need for more evidence-based research, further experimentation for innovative technological developments, high investments, difficulties accessing financial support, underdeveloped business cases, limited recognition of UA's benefits, and behavioral/cultural barriers.

2024Moye Eric Kongnso · International Journal of Environment Agriculture and Biotechnology · Cameroon
A mixed-methods study in the West Region, Cameroon, examined compost use in urban farming through 265 household surveys, 11 in-depth interviews, and one focus group. While compost availability and technical assistance favor its use, small-scale farmers face significant technical, knowledge, financial, institutional, and policy constraints. State extension services prioritize mineral fertilizers over compost, and the current regulatory framework does not encourage compost use, leading to the persistence of traditional practices.

This study provided advisory support to an urban garden in Bogotá, Colombia, named "Guerreros y Guerreras Unidos en Accion," which had been operating empirically since 2005 without formal legal status or strategic planning. The garden, primarily involving individuals over 50 without formal employment, sought to formalize its activities by establishing a foundation. The intervention aimed to guide the garden's members through the legal and administrative steps for formalization.

2015David Mkwambisi, Andrew J. Dougill, Philip Antwi‐Agyei, C. P. Chabvuta · CABI eBooks · Malawi
Research in Lilongwe and Blantyre, Malawi, assessed urban agriculture's potential to improve soil quality, crop yields, and livelihoods. Preliminary evidence showed urban waste could address food insecurity and soil nutrient benefits, but several constraints in waste management were identified. City authorities are not proactively utilizing organic municipal waste for soil quality and agricultural production benefits.

2014Yuki Sampei, Yuji Hara, Akinobu Murakami, Armand PALIJON, Kazuaki Tsuchiya, Makoto Yokohari · Journal of The Japanese Institute of Landscape Architecture · Philippines (Metro Manila)
The nitrogen supply-demand balance in compost and vegetable production on vacant lots in suburban residential districts of Quezon City, Metro Manila, was assessed. Analysis revealed that almost half of the subdivisions faced nitrogen oversupply, while several were in short supply. Current centralized composting facilities may not adequately support a continuous compost recycling system due to their distribution patterns. It was proposed that existing barangay-based policies on organic waste management and urban agriculture require greater flexibility and attention to coordination systems across subdivision boundaries.

2014Yuki Sampei, Yuji Hara, Akinobu Murakami, Armando M. Palijon, Kazuaki Tsuchiya, Makoto Yokohari · Institutional Repositories DataBase (IRDB) · Philippines
This study assessed the nitrogen supply-demand balance in compost and vegetable production on vacant lots in subdivisions and barangays in Quezon City, Metro Manila, using GIS. It found that nearly half of the subdivisions experienced nitrogen oversupply, while others faced shortages. Although cooperation among subdivisions within a barangay could improve nitrogen balance, the current centralized composting facilities were deemed insufficient to support a continuous compost recycling system due to their distribution patterns. The study concluded that current barangay-based policies on organic waste management and urban agriculture need greater flexibility and attention to inter-subdivision coordination across barangay boundaries.

2011Marie-Christine Zélem, Zelem, Marie-Christine · AgEcon Search (University of Minnesota, USA) · Senegal (Dakar)
This study identifies numerous constraints hindering the widespread adoption of organic waste utilization in agriculture in the peri-urban area of Dakar, Senegal. These constraints include the nature, availability, and accessibility of organic waste, poorly controlled urbanization, effects of seasonal variation, resistance to changes, and medical risks. The project, which combines agriculture with city waste management, faces these challenges.
