This case study examines collaborative governance between local authorities and community stakeholders in Palembang, Indonesia, a low-lying delta city on the Musi River facing recurrent flooding, food insecurity and disrupted supply chains driven by urban expansion, poor drainage infrastructure and climate-related rainfall variability. It analyzes local policy responses, community-led initiatives such as floating vegetable gardens, and urban farming on flood-resilient land, finding that while municipal disaster agencies provide early warning and evacuation support, food access and distribution during floods are primarily sustained by grassroots networks and community-organized food banks.

A survey of 330 peri-urban farm households in Hyderabad, India, using multi-stage sampling and a Double Hurdle Model to analyze the decision to diversify farm activities and the intensity of that diversification. Results show the initial decision to diversify is strongly shaped by socio-environmental factors — proximity to urban areas, sole reliance on farming for income, household size and risk attitudes — while diversification intensity is largely determined by farm-specific resource conditions such as soil fertility and farmers' subjective assessment of production and market uncertainty. The study concludes that peri-urban farms in India are moving toward diversification, but at low intensity, particularly among small and semi-medium landholdings.

This study assessed the economic feasibility of Yurga Farm, a farmer group participating in Surabaya City's urban farming program in East Java, Indonesia, which cultivates horticultural vegetables — including pakcoy, romaine, siomak, lettuce, kale, samhong and caisim — on narrow but productive urban land. Primary data on production costs, revenue and income were collected through in-depth interviews. All commodities showed an R/C ratio above 1, with break-even-point (BEP) production levels below actual production and BEP prices below selling prices, indicating the farming business is profitable and has potential for sustainable development.

A study of Beijing and Shanghai, China (2025) modeled decarbonization from adjusting the local-sourcing share of seven perishable food categories — vegetables, poultry, aquatic products, beef, and lamb among them — incorporating both production and cold-chain logistics emissions across multiple localization scenarios. Each 1% increase in localization of vegetables, poultry, and aquatic products cut 2020 emissions by 0.4-1.9 tCO2e, while the same 1% increase for beef and lamb raised emissions by 0.2-2.9 tCO2e; localization reduced the cold-chain emission share for every food category. A constrained "balancing strategy" cut 2020 emissions by about 0.76 MtCO2e (5%) in Beijing and 0.44 MtCO2e (2%) in Shanghai, and an unconstrained scenario maximizing urban agriculture use achieved 3-4 times more reduction. Under a business-as-usual projection, the strategy was estimated to offset over 90% of Beijing's added emissions by 2035, with a further 0.44 MtCO2e reduction possible in Shanghai. The findings indicate that importing more carbon-intensive ruminant meat while reallocating urban resources toward vegetables, poultry, and aquatic products could produce more sustainable food supplies in megacities.

Six heavy metals (lead, cadmium, chromium, nickel, copper, zinc) were measured by atomic absorption spectrophotometry in spinach, amaranth and fenugreek collected from four peri-urban sites around Dhaka, Bangladesh, during January-March 2024, where more than 2,000 hectares of vegetable land are irrigated with untreated industrial and domestic wastewater via canal networks. Lead in amaranth from the industrial-effluent site reached 0.94 mg/kg fresh weight, more than three times the WHO/FAO permissible limit of 0.30 mg/kg, while cadmium, chromium and nickel stayed within permissible limits at all sites and zinc, though highest in absolute terms (8.6-14.7 mg/kg), also remained within safe limits; contamination was highest at the industrial-effluent site and lowest at the borewell-irrigated control site, indicating a localized food-safety risk for consumers of peri-urban leafy greens grown with wastewater irrigation.

This review paper positions hydroponics—a soilless cultivation technique—as a method of urban agriculture addressing confined land availability, food security, and environmental concerns from urbanization, focused on Kathmandu, Nepal. It synthesizes existing insights on setup costs, operational challenges, and profitability against global trends and local constraints, and, framing setup costs and operational challenges as barriers to adoption, recommends subsidies, training, and integration into urban planning as pathways to foster the uptake of hydroponic farming.

Myung‐Bok Lee, Daojian Chen, Fangyuan Liu, Fasheng Zou · Basic and Applied Ecology · China (Guangzhou)

This study investigated how spatial and temporal crop changes relate to bird diversity and traits in small peri-urban agricultural lands in Guangzhou, a sub-tropical city in China. Bird and crop data were collected approximately bimonthly from December 2021 to October 2022. Both overall crop diversity (alpha diversity) and seasonal crop changes (beta diversity) were positively associated with bird Shannon-Wiener diversity. Woody vegetation cover positively affected all three bird diversity indices, while plant/seed-eating bird abundance was negatively associated with alpha crop diversity, and ground-foraging bird abundance was positively associated with beta crop diversity.

This study used Demographic and Health Survey (DHS) data to identify which households raise livestock in urban and peri-urban areas of eight developing Asian countries. Results show that at least 10% of households keep livestock, with over 30% in four countries practicing urban and peri-urban livestock farming (UPLF). Poultry is the most common livestock, and poorer families are more likely to raise livestock, suggesting UPLF can improve food and nutritional security for low-income households.

This literature review study examines the concept of urban farming as a solution to agricultural challenges in cities with little or no traditional farmland. Drawing on literature covering urban farming practices in major cities worldwide facing land constraints, it summarizes techniques including hydroponics, aquaponics, vertical farming, and use of rooftops or vacant urban spaces. The review finds urban farming can improve access to fresh food, reduce emissions from food transport, and improve environmental quality through increased green space, while also empowering local communities through job creation and resident involvement in food management, and supporting organic waste management by using household waste as fertilizer. However, resource constraints such as water, fertilizer and technology, along with regulatory and policy issues, were identified as the main barriers to implementation, and the paper concludes that collaboration among government, the private sector and local communities is needed.

Setyardi Pratika Mulya, Delik Hudalah · Regional Sustainability · Indonesia

This study assessed sustainability based on agricultural intensity in peri-urban villages of Karawang Regency, Indonesia, using a village agriculture index (VAI), a village sustainability index (VSI) adapted from a local sustainability index via factor analysis, and a logical matrix analysis for level of agricultural sustainability (LoAS). Peri-urban villages with high agricultural intensity tended to show lower social welfare and economic development and higher disaster risk; high agricultural intensity did not necessarily ensure prosperity, and economic disparity existed among villages, leading the study to conclude that encouraging diversity in agricultural intensity is more important than promoting agricultural intensity itself.

Addressing the high temperatures characteristic of urban planting conditions in Gresik Regency, Indonesia, this paper proposes optimizing post-harvest sales and storage systems for urban farming products through three measures: planting and harvest scheduling by crop type and duration, cold storage to slow quality degradation and extend shelf life, and a sales and distribution application. It identifies as a problem that most current sales of urban farming products depend on direct sales to the surrounding community and are considered ineffective, and proposes that these three measures would let farmers reach customers beyond Gresik.
