This study evaluated the effect of different land uses on soil health indicators in peri-urban agricultural areas of Yaounde, Cameroon, by comparing five tilled sites with native forest land. While most cropped land showed higher levels of many soil health indicators, cultivation of crops like corn and sugarcane significantly impacted native soil quality. Specifically, phenol oxidase, microbial biomass C/organic C, and microbial biomass C/microbial biomass P were negatively affected, indicating negative management impacts on soil health.

This paper reports on research exploring how alternative agricultural approaches, such as Organic Agriculture, Biodynamics, Permaculture, CSAs, Farmers Markets, and Community Gardens, contribute to more resilient agri-ecological systems and communities. These systems are reviewed in relation to key concepts from ecological systems thinking, including ecological resilience, biodiversity, and holism. The paper discusses how these systems contribute to more sustainable and resilient communities through community development processes like relationship building, genuine participation, inclusiveness, resource mobilization, and creating space for knowledge sharing.

While favorable aspects of denser urban development are recognized in Australia and elsewhere, this study also highlights its negative impacts on a city's climate and hydrology. It summarizes the appealing aspects of denser cities and provides examples of adverse effects. Strategies to minimize these negative impacts are proposed, including the widespread use of rooftop gardens.

Karin Andersson · · Sweden

This study analyzed Ramsjo gard, the only Community Supported Agriculture (CSA) farm in Sweden, from a sustainability perspective using a mail survey of CSA members and a farm sustainability analysis. The survey found no statistically significant relationship between farmer-member contact and member learning, nor between member learning and changes in food purchasing habits. The sustainability analysis indicated that farmers perceived social and environmental aspects as more sustainable than economic and practical ones.

Zhu Mi-juan · Ecological Economy · China

This paper reviews prior research on urban agriculture and compares Chinese and foreign urban agriculture in terms of their emergence, scope, industry structure, development direction, and functions. It concludes that the basic development models used in foreign countries are not suited to China and that China should build its own "sustainable" (continuable) development model by modernizing and adapting elements drawn from foreign sustainable agriculture practice, rather than adopting foreign models directly.

The 'Climate Outlooks and Agent-Based Simulation of Adaptation in South Africa' project investigated how seasonal climate outlooks influence agricultural strategies and food security among smallholder farmers in Vhembe district, Limpopo Province, South Africa. Empirical field data, collected through surveys and participatory approaches, informed an agent-based social simulation. This simulation modeled household agents with varying adaptation options, examining the impacts on crop yields and food security based on whether seasonal outlooks were used or ignored.

André Viljoen, Katrin Bohn · University of Brighton Repository (University of Brighton) · United Kingdom (London)

This paper, from a U.K. perspective, discusses urban agriculture using London as an example. While the benefits of urban agriculture for food security and income have often focused on the Global South, its integration into a multifunctional land use strategy could significantly reduce a city's ecological footprint, raising questions about its wider implementation.

The integration of agriculture into urban landscapes has a long history, intensifying since the industrial revolution, with early "garden cities" remaining utopian ideals. In contemporary urban development, renewed interest in agriculture relates to implementing sustainability and addressing globalization's structural changes to communities, food systems, and urban quality of life. Urban agriculture is a strategic resource requiring a strategic planning approach that recognizes its economic, social, and environmental values.

E. Omomoh, C. O. Adeofun · · Nigeria

This study assessed urban agricultural land use changes in Jos-Bukuru, Nigeria, between 1961 and 2002 using a geospatial information system. It found that agricultural land use substantially increased from 1961 to 1986. However, between 1986 and 2002, approximately 63% of agricultural land was lost, with about 68% of this loss attributed to urban development. The study concludes that while urban spatial expansion is increasing, agricultural land use is decreasing.

This field survey in the Modder River basin, South Africa, investigated the potential expansion and implications of a rainwater harvesting technique introduced to small-scale farmers. While a rapid spread within home yard sizes was expected, no significant spread to community gardens or beyond was anticipated in the short term. This limitation was attributed to socio-economic constraints, including poverty and a lack of appropriate tools and basic farming skills.

Peter M. Philippi (Green Roof Service, LLC) · U.S. Environmental Protection Agency (EPA) · Germany

This paper, hosted by the U.S. EPA, introduces the German non-profit FLL's (founded 1975) 'Guideline for the Planning, Execution and Upkeep of Green-Roof Sites' (latest edition January 2002, English version 2004) to the American market. The guideline draws on the experience of roughly one billion square feet of green roofs built in Germany, and includes specific standards such as organic matter content limits for growing media (e.g. 6.0% by dry mass or less for intensive green roof media above a given density) and a root-penetration resistance test (revised to a two-year protocol in 1995, with about 70 membranes having passed it so far).

Leigh Holland · Local Environment · United Kingdom

This 2004 study in the United Kingdom analyzed the community garden movement through questionnaires and in-depth interviews. It found that community gardens, often in inner-city areas, serve diverse purposes including vegetation growing, permaculture, organic methods, health, education, and training. These gardens are strongly characterized by community participation and involvement, suggesting the movement could model local social, economic, and environmental policy implementation.

Urban agriculture in Shenzhen faces problems including decreasing farmland, inadequate skilled farmers, poor disaster resistance, immature insurance, increasing contamination of water, soil, air, and agricultural products, and poor modern enterprise management. Strategies proposed for sustainable development include specific laws, pollution protection, education, research, technology application, industrial technology application, leisure agriculture development, and diversification.

Marc Lavergne · HAL (Le Centre pour la Communication Scientifique Directe) · Europe

While urbanization and agriculture often appear contradictory, the existence of urban agriculture (intra-urban and peri-urban) in the Mediterranean basin demonstrates that their relationship is not as clear-cut. Urban growth consumes agricultural land, and urban and rural worlds seem radically opposed in lifestyles and values. However, urban agriculture has forged complex relationships with the urban environment, involving both antagonisms and complementarities.

Arjan van Timmeren, Wiek Röling, Marleen Kaptein · · Netherlands (Culemborg)

This paper focuses on an innovation in urban development in the Lanxmeer district of Culemborg, Netherlands. A "Sustainable Implant (SI)" based on permaculture and organic design principles will be built in conjunction with the EVA-Center and an ecological city-farm. The SI functions as an interconnector for three "essential" flows in urban planning, such as wastewater management and energy generation, facilitating both vertical and horizontal integration. It is considered a sustainable hub operating at three scales: the Culemborg region, the Lanxmeer urban district, and the nearby EVA Center.

Brian Halweil · · Global

This book points out that the long-distance food system consumes staggering amounts of fuel, generates greenhouse gases, and compromises food security. Since 1961, the tonnage of food shipped between nations has grown fourfold, with food in the United States typically traveling 1,500 to 2,500 miles from farm to plate. While this system often runs roughshod over local cuisines, varieties, and agriculture, a local-foods movement is beginning to emerge globally.

Shaohua Yin · Economic Geography · China

This essay discusses a development strategy for building green cities in Hunan, China, proposing four aspects: relying on green concepts, developing the green economy, establishing scientific urban layout, and emphasizing urban agriculture. It argues such a strategy must be treated not as a slogan but as a systematic science, concept, belief and way of life requiring everyone's effort and comprehensive coordination, without presenting specific data or study findings.
