Quintana Piñeros, Jacqueline Lisette · · Colombia (Bogota)

This proposal is based on studying the climatological behavior of the main Bogota River basin and its vegetation characteristics to identify suitable native species for urban agriculture. It also proposes a rainwater harvesting system design for hard surfaces, specifically the laboratory building terrace at El Porvenir citadel of Universidad Distrital Francisco José de Caldas. The system would comprise storage, transport, and filtration systems, culminating in a drip irrigation system.

This paper presents an interdisciplinary scheme to evaluate the sustainability of urban rooftop agriculture (URA), investigating its quantitative and qualitative potential, and environmental and economic impacts. Using Barcelona, Spain, and Bologna, Italy, as case studies, four interdisciplinary methods were combined: qualitative research, geographic information systems (GIS), life cycle assessment (LCA), and life cycle costing (LCC). Results indicate that a combined GIS-LCA tool is useful for evaluating URA implementation and its environmental benefits at the city scale, with soil cultivation using compost in open-air rooftop gardens being the most eco-efficient option.

Land Use Land Cover (LULC) changes in Johannesburg City, South Africa, were analyzed using Landsat imagery from 2000 to 2016. The analysis revealed that impervious surface increased by 57.03% during this period, leading to a 47.8% loss of urban vegetation (grass, tree cover) and urban agricultural land. Additionally, soil and water loss amounted to 16.75%.

This chapter provides an outlook on how soil-based agriculture for growing food crops in urban areas can be strengthened. Credible assessments of the importance and extent of urban agriculture (UA) are challenging due to numerous and disparate definitions of UA. UA offers many benefits, particularly contributing to urban food security in high-income countries by providing fruits and vegetables. Urban soil properties differentiate the type and value of food produced, but urban soil quality can be improved for crop production.

This dissertation addresses agricultural extensification from several angles. Chapter 1's literature review showed an increase in research on urban and peri-urban agriculture (UPA) and ecosystem services, but highlighted a need for quantifying ecosystem services and functions to clarify ecological tradeoffs. Subsequent chapters focused on a mixed-methods study in New Hampshire, surveying approximately 600 residents (494 general population, 103 food system stakeholders) on their perception of forestland conversion to agriculture.

This article analyzed the environmental benefits of rooftop gardens as part of urban greenery systems in Malaysia. An in-depth interview with seven experts revealed a consensus that rooftop gardens can effectively address several urban environmental issues. However, the study emphasized that the function and purpose of the rooftop garden must be considered during design and construction to fully achieve its objectives, whether for recreation or environmental purposes.

A study analyzing the sustainability level of urban farming in Makassar City, Indonesia, found that the overall urban farming sustainability index was 48.52%, indicating a "less sustainable" status. The ecological dimension was rated 42.66% as "less sustainable," while the economic dimension was 50.69% as "fairly sustainable."

This paper discusses design procedures and criteria for vertical gardens (living walls) and green roofs. Vertical gardens are suitable for urban areas, offering uses like urban agriculture, while green roofs provide ecosystem services such as mitigating urban heat island effects and improving biodiversity. Both technologies are recognized globally for environmental benefits, with a thriving industry and extensive research, particularly in Europe.

This research investigated pakis-stem blocks as a growing medium for green roofs, evaluating their 3-in-1 function as a lightweight growing medium, an easy-to-form urban farming system, and an eco-friendly external roof insulation. Measurements on rooftop surface and room thermal behavior showed that pakis-stem green rooftops reduced surface dry-bulk temperature by 16.4°C and ambient room dry-bulk temperature by approximately 7°C at noon compared to conventional rooftops. The surface and ambient room air temperature differences between pakis vegetative green rooftops and miana scrub green rooftops were approximately 7°C and 3°C, respectively.

The objective of this study is to propose water retention features to reduce peak urban runoff at source during storm events in an urbanized area. The report focuses on applications in a decentralized area with a centralized system. The three main proposed features are water towers, rooftop gardens (planter tanks), and permeable pavements, intended for implementation in residential housings such as HDB public housings. The study aims to determine how much water can be delayed during high rainfall, and computations and reasoning for these features are discussed.

This chapter highlights three main points regarding urban cultivation. First, urban cultivation is much more than producing food. Second, it should be seen as a normal and accepted livelihood in all urban areas, requiring land rights and regulatory environments to align with this reality. Third, urban cultivation has a critical role in making cities sustainable, green, and more resilient in the future.

This text discusses how custom production, facilitated by technologies like 3-D printing, challenges traditional mass production theories. It notes that urban agriculture is exploring experimental, low-impact production methods to integrate urban surfaces into food production for a growing urban population. The high costs of mass production prototypes can be significantly reduced by 3-D printing, allowing for greater product variation at lower costs.
