Urban expansion and food security implications: A three-decade analysis of land use change in Kinondoni district, Dar es Salaam, Tanzania (1993-2023)
2026Adili Y. Zella · African Journal of Social Issues · Tanzania
This study analyzed land use and land cover (LULC) changes in Kinondoni District, Dar es Salaam, Tanzania, between 1993 and 2023 using multi-temporal Landsat satellite imagery. The analysis revealed that built-up areas expanded by 1,433%, from 124.20 ha in 1993 to 1,905.14 ha in 2023. Concurrently, cultivated land decreased by 96.6%, from 172.90 ha to 5.88 ha, representing a loss of 167.02 ha. The near-complete elimination of cultivated land in Kinondoni District indicates a critical threat to local food production capacity and urban food security.

2026Never Assan, Justice Sibanda, Betty Mukuwapasi, Reason Rumbidzai Charachimwe, Edmore Masama · Journal of Frontiers in Multidisciplinary Research · Sub-Saharan Africa
Urban animal agriculture (UAA) in Sub-Saharan Africa is presented as a solution for food security but faces challenges including gender inequality, climate change, inadequate legislation, and environmental degradation. While UAA aims to enhance household food security and alleviate poverty, it also encounters environmental issues such as resource competition, water resource strain, improper manure management, greenhouse gas emissions, noise, and nuisance. Sustainable UAA requires semi-intensive silvopastoral and mixed crop and livestock systems to reduce environmental impact and enhance local food production.

2026James Vandenberg, Kerstin Krellenberg · Sustainable Cities and Society · Global
This study investigated how differentiated configurations of outdoor, indoor, and greenhouse urban agriculture (UA) impact Urban Resilience Capacities (URCs). It found that a strategic, place-based, combinatorial approach to integrating UA typologies can produce mutually reinforcing outcomes, strengthening various URCs simultaneously. However, a strong risk of trade-offs exists when UA systems are not aligned, and a critical research gap remains as empirical case studies are concentrated in Europe and North America, overlooking experiences in the Global South.

2022Imen Bendjemila, Salah Chaouche · DOAJ (DOAJ: Directory of Open Access Journals) · Algeria
Urban sprawl in N'Gaous, Algeria, expanded its land area by over ten times (from 33.7 to 379.7 hectares) and its population by over six times (from 4,887 to 33,515 persons) over 60 years. This rapid growth creates significant issues, particularly for peri-urban orchards, which are the primary economic activity. The study used an analytical approach with Geographic Information Systems to assess the agronomic potential of soils and quantify agricultural land consumed by construction, aiming to achieve an optimal agri-urban balance rather than merely avoiding urban expansion.
