The project was presented in the 8th World Sustainability Forum in 2020.

Arguably, humanity worldwide continues to experience in the interests for urban growth scenario despite adverse characteristics shown in the epoch of Anthropocene. The focus of the project seeks to investigate adaptive design pathways to address future urban farming scenarios with less assertive anthropogenic activities. The expected outcome aims to contribute to better strategize microclimate towards operational-useful sustainable and resilient agricultural practices.

Arguably, humanity worldwide continues to experience in the interests for urban growth scenario despite adverse characteristics shown in the epoch of Anthropocene. These characteristics in-turn, challenges the operational pathway in SDGs, particularly 2-4 Sustainable Food Production and Resilient Agricultural Practices. Whilst impacts lead to reduced nature-green and water holding open spaces in rapid built-up environments, the role and capability of water resources for resilient agricultural practices in cities continue to disassociate with sustainable food production by design. This correlated directly and falling short to achieve another SDGs 11-3, Inclusive and Sustainable Urbanization. The focus of our research seeks to investigate adaptive design pathways to address future urban farming scenarios with less assertive anthropogenic activities but through bio-inspired and life-friendlier developmental design nexus by coupling intrinsic design relations between SDGs: 2-4, 11-3 and 13-1. The expected outcome aims to contribute by illustrating translational knowledge for a different but vital life-friendly biomimicry urbanism design in order to better strategize microclimate towards operational-useful sustainable and resilient agricultural practices.

Currently, the rapid increase of global warming created by human activity from Land Use changes has impacted the Urban heat island effect. Many of these issues derive from the change of forest, wetlands and grasslands into agriculture land, which alters the flow of the water cycle and directly impacts the natural carbon cycle. In the year 2070, due to needed space for agriculture and human settlements, a different urban layout is essential.

Urban Micro-climate

The United Nations estimates that up to 70% of the world’s population will live in urban areas by 2070. These projections are based on the UN World Urbanization Prospects and its median fertility scenario. Urbanization adds to major landscape transformations. The heat is trapped between buildings which makes it hard for cities to be cooled at nights. The nightly temperature in the city differs about 7°C to the countryside temperature.
