A participatory education program for household-level climate adaptation was delivered to seven housewives belonging to the Rumah Keluarga Indonesia community. The curriculum covered climate change impacts on food production, water and energy availability, the use of home yards for food production through urban farming with household organic waste, and simple technologies such as small solar panels for yard lighting. Following the activity, participants showed strong engagement and reported increased understanding and awareness of women's role in household food, water and energy resilience to climate change.

A study assessed the sustainability status of seven types of urban agriculture in Malang City, Indonesia — irrigated agricultural land, rainfed dryland farming, recreational activity, community gardening, commercial farming, agro-educational tourism, and institutional farming — using multidimensional scaling with the RAPHYTON tool. Primary data came from expert and supporting informant interviews plus field surveys and observation. Results showed the sustainability level of urban agriculture types in Malang City was generally in the "moderately sustainable" category. The ecological dimension of irrigated agricultural land was classified as unsustainable, while agro-educational tourism achieved the highest sustainability status, rated sustainable in the social dimension.

Set against the backdrop of accelerating urban stock renewal in China, this paper addresses the contradiction between "quantity" and "quality" in developing high plot ratio land—where rigid plot ratio constraints create physical barriers such as insufficient lighting, chaotic circulation, and lack of public space, while demand for quality living raises requirements for spatial openness, ecology, and social inclusiveness. It analyzes design strategies including composite utilization of underground space, ecological compensation through rooftop gardens, and cross-plot three-dimensional corridors, combined with coordination of ownership division, full-process cost control, and policy tool innovation, to construct a comprehensive improvement mechanism of "physical optimization, ownership coordination, and economic balance," intended to provide a replicable design paradigm and decision-making reference for improving the quality and efficiency of existing land in high-density urban development.

An experimental study at the Seed Technology Laboratory of Universitas Sriwijaya, Indonesia, conducted in September 2025, tested simple seed priming treatments on four commercially marketed leafy vegetable seed types used in urban farming — butterhead lettuce, red romaine lettuce, green lettuce, and napa cabbage — using a factorial completely randomized design. Seeds received one of four treatments (untreated control, 60°C warm water for 15 minutes, 60% shallot extract for 30 minutes, or 70% coconut water for 30 minutes), and germination was recorded every 6 hours over 48 hours. Warm water priming reduced the time to 50% germination (T50) from 36.69 hours in the control to 18.48 hours, and shallot extract reduced it to 19.38 hours, indicating faster germination; the authors note this still requires validation under nursery or field conditions.

A study for the "Buruan SAE" (Healthy, Natural, Economical) urban farming program in Maleer, Bandung City, Indonesia, designed and developed a Business-to-Consumer (B2C) e-commerce website to address marketing and sales problems previously handled through word-of-mouth and manual paper-based records. Citing suboptimal market penetration, stock uncertainty for prospective buyers, and high financial-loss risk given vegetables' perishability, the project used a risk-driven Spiral model methodology, collecting data through interviews, observation, and literature study. Business process analysis identified four main problem areas: product publication, stock management, ordering and transactions, and financial recording. The study reports that a structured web-based e-commerce system can shorten the distribution chain, ensure catalog-stock synchronization, and minimize manual recording errors.

· Wikipedia · India

This Wikipedia article gives an overview of Indian agriculture. It states that agriculture employs more than 50% of India's workforce and contributes 20.2% to GDP per the 2020–21 Economic Survey, while productivity remains 30–60% of that in developed countries. The article does not specifically address urban farming, focusing instead on structural issues such as infrastructure gaps and farmer suicides.

Indonesian politician Ridwan Kamil (born 1971) served as mayor of Bandung from 2013 to 2018. Before becoming mayor, he was a pioneer of the 'Indonesia Berkebun' (Gardening Indonesia) urban farming movement, which had grown to 14 cities with about 4,000 members by 2011. As mayor, he also worked pro bono on creating public open spaces in crowded residential areas of Bandung.

· Wikipedia · Taiwan

The Wikipedia article 'Agriculture in Taiwan' summarizes Taiwan's agricultural sector. As of 2023, agriculture accounts for 1.51% of GDP with an output value of roughly NT$35.1 billion; there were about 760,000 farm households in 2022, and food self-sufficiency stood at 35% in 2020. The article notes Taiwan's growing vertical farming sector, including iFarm in Taoyuan, described as Asia's largest vertical farm as of 2018.

The Wikipedia article on Taiwan's Ministry of Agriculture traces its lineage: the Council of Agriculture was formed under the Executive Yuan in 1984, and in May 2023 the Legislative Yuan passed the Organic Act elevating it to full ministry status as the Ministry of Agriculture, overseeing agriculture, forestry, fishery, animal husbandry and food affairs.

This Wikipedia article on recycling in South Korea (the URL 'Food_waste_in_South_Korea' redirects here) describes a pay-as-you-throw system requiring households to buy designated bags for general waste separate from food waste. The food-waste recycling rate rose from 2% in 1995 to 95% by 2013. Per-capita food waste generation exceeds 130 kg/year, and RFID-enabled smart bins reduced food waste by 47,000 tonnes over six years. South Korea's overall recycling rate reached 59% in 2013, the second-highest among OECD countries; daily household waste fell from 1.3 kg (1994) to 0.94 kg (2013) while the recycled share rose from 15.3% to 83.2%.

This Wikipedia article on waste management in Taiwan describes a recycling programme that began in 1989 following a 1987 amendment to the Waste Disposal Act, with the 3R Foundation established in 1994. There are 33 recyclable items across 13 categories; raw food waste is processed into fertilizer for farmers while cooked food waste is converted into livestock feed. As of August 2023, 25 large-scale incineration plants operate, 22 publicly owned (5 publicly operated, 17 privately operated) and 3 privately owned and operated. In 2016, 76.8% of fly ash from coal-fired power plants (1.703 million tons) was reused in construction.

Sponge city is a Chinese urban planning model that uses green and wetland infrastructure to absorb, purify, and store rainwater. China piloted the model in 16 districts in 2015 and a further 15 cities in 2016, with a central government mandate that 80% of urban space adopt sponge-city adaptations and recycle at least 70% of rainfall by 2030. However, 19 of the 30 pilot cities have still experienced flooding since implementation, indicating implementation challenges.

Singh C., Koduganti M., Patil S. · Urban Studies · India

A study measuring the self-reported wellbeing outcomes of urban agriculture in India at individual and community level, drawing on a household survey (n=361), key informant interviews (n=50) and in-depth interviews with home gardeners (n=7). Its novelty is a dataset covering both formal and informal settlements, going beyond existing Indian data. Wellbeing is operationalised through physical and mental health, intra-family, community and beyond-human connectedness, and contribution to pro-environmental values. The authors find significant perceived benefits at individual, household and community levels, and that urban agriculture lets citizens participate, innovate and collectivise in deeply meaningful ways — concluding that it needs to be recognised and mainstreamed within ongoing urban sustainability and climate initiatives.

A quantitative assessment of rooftop agrivoltaics (RAV) — co-locating solar PV and crops on building rooftops — against the SDGs. For the Yangtze River Delta urban agglomeration (~10,720 km² of rooftops) it estimates ~93.1 TWh/year of electricity (6.3% of regional demand), ~43.6 Mt/year of lettuce, large job creation, and ~127 Mt/year of CO2 reduction, positioning RAV as a multifunctional urban land-use that pairs 'zero food miles' food production with clean energy.
