This research developed an integrated scheduling model for seedling and planting in urban agricultural products, considering seedling time, land availability, land productivity, selling price, and cost aspects. The model was tested with scenarios including increased demand, changes in land yield, changes in agricultural land area, and changes in harvest prices. Scenario test results indicated that agricultural land area and land yield were the most sensitive factors.

This study in the Middle East and North Africa region investigated the relationship between urban agriculture and food security in two peri-urban locations: Bebnine, Lebanon, and Wadi el Seer, Jordan. High food insecurity was prevalent in both locations, demonstrating that producers were more food insecure than non-producers. Food security was found to be strongly associated with poverty and the number of household members.

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.

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.

This qualitative study in peri-urban Uppsala, Sweden, identifies driving forces influencing land use decisions by commercial farmers and institutional landowners. It notes that approximately 700 hectares of land in Sweden are diverted from food production annually, with Uppsala Municipality showing the greatest change in 2013. The expropriation of agricultural land for urban development leads to farmers losing land resources and increased competition for remaining land, resulting in high land prices.

In Lubumbashi, Democratic Republic of the Congo, researchers analyzed the fertilizing value of different types of biowaste used in urban market gardening through principal component analysis of grower profiles, chi-square analysis of practices, and physico-chemical analysis of the waste materials. Most market gardeners were married women over 18 without land title; half the biowaste used was purchased chicken manure (with some pig manure), applied raw and buried in the soil, and while 33% of growers expected spreading it to increase productivity and improve soil physico-chemical properties, 48.3% expected it to improve vegetable growth appearance and boost yield.

This review paper examines the concept and role of peri-urban agriculture (PUA) as a contributor to solving urban food crises in developing countries. It reviews the historical development and current state of PUA across different parts of the world in relation to rising urban vegetable demand, noting that agricultural communities engaged in PUA make multifunctional contributions to national economies. As approaches to PUA vary by country, the paper argues it is the community's role to identify the functions that benefit local people most, and discusses how PUA, through community and rural development, can boost urban food supply and serve as an income-generating option for farmers in developing countries.

Sarah James · Geographical Research · Australia (Sydney)

This paper examined the failure of Sydney's 'green zones' farmland protection policies, which were abandoned due to protests. The failure was attributed to a lack of consultation with Sydney's diverse small-scale farmers, rather than a rejection of farmland protection itself. Farmer interviews suggested that a bottom-up policy-making approach would have been more successful in maintaining farming in peri-urban areas.

This paper explores sustainable financing for urban agriculture, particularly as part of the sanitation value chain. Financing is considered from two perspectives: an adequate mix of public, private, and local finance to avoid external funding dependency, and the purpose of investment focusing on value chains in the sanitation and (peri)urban agricultural sectors. The emphasis is on exploring financing options for urban agriculture through the valorization of urban waste, aiming for clear beneficial impacts on the urban and peri-urban agricultural sector.

This article reviews changes in farm output and structure in peri-urban regions around Australia's cities. It concludes that farming in these regions is changing differently from other agricultural regions, with productivity centered on a few high-value activities. The majority of peri-urban farming, while potentially providing landscape services, is unable to adjust to changing productivity regimes, creating vulnerabilities for these farming systems.

This paper discusses the use of untreated wastewater for irrigation in urban and peri-urban agriculture, noting its prevalence in four out of five cities in the developing world according to a 2008 survey. It highlights that local policymakers are often unaware of the significance and opportunities of this practice, despite its potential for nutrient recovery and integration into urban sanitation systems. Planning for wastewater use requires multi-agency involvement.

Climate change and its impacts on peri-urban agriculture were investigated in four peri-urban villages in the Kathmandu valley, Nepal. Temperature showed an increasing trend, while rainfall was erratic with no distinct pattern. These changes primarily had negative impacts on agriculture, leading to increased crop pests and diseases and a decline in crop production.

This paper discusses the fusion of urban agriculture, ecotourism, and cultural innovation as a necessary approach for industrial upgrading, value creation, and income improvement in suburban areas. It outlines four methods for this fusion: government-led corporate development, market-guided corporate management with government support, market and policy-guided collective development, and individual development with villager participation based on government-provided infrastructure. The paper suggests that different villages and towns should adopt the most suitable route based on local conditions.

This paper presented an integrated DEMATEL and ANP technique to evaluate land for peri-urban agriculture in the Qazvin Plain, Iran. Ecological word model, slope, climatic soil properties, water resources, and vegetation density were chosen as major factors and evaluated using a Multi Criteria Decision Making (MCDM) model. Results confirmed six classes of agricultural land use, indicating that northern parts are not suitable for agriculture development. However, 98,598.20 hectares of polygons were determined to be extremely to medium suitable for agriculture.

This paper discusses rainwater management in the "niayes" zone of Dakar, Senegal. This area is characterized by agricultural depressions with typically high groundwater levels, but a recent drop has turned some into runoff-gathering sites, used for urban agriculture among other services. However, two acute problems are observed: hydrological drying due to insufficient rainwater refill and urbanization of these bottom-lands. Furthermore, decreasing pluviometry exacerbates nuisances like floods and malaria.
