Sustainable Urban Agriculture Integration With Photovoltaic and Rainwater Systems

Project in-detail

Utilizing rainwater harvesting and photovoltaic systems, the development integrates sustainable agricultural practices into an urban landscape while serving as a community hub for local food production.
5 key facts about this project
01
Integrates an extensive rainwater harvesting system designed specifically for arid conditions.
02
Utilizes photovoltaic panels installed on multiple building elevations for maximum energy capture.
03
Features raised planting beds to optimize crop yield and minimize water usage.
04
Incorporates a community market space adjacent to urban gardens for enhanced local production access.
05
Employs a bent A-frame design that enhances structural efficiency and aesthetic appeal.

The architectural project "Lesatsi le Pula" (Sun & Rain) is situated in Gaborone, Botswana, and addresses the critical environmental challenges of the region through an innovative integration of sustainable practices. This development focuses on the intersection of agricultural innovation and renewable energy, emphasizing a self-sufficient model that supports local food production while harnessing natural resources.

This project represents a comprehensive approach to urban sustainability, utilizing solar energy and rainwater harvesting to mitigate water scarcity and energy dependency. It serves not only as an agricultural center but also as a hub for community engagement, highlighting the importance of local produce and fostering interaction among residents.

Sustainable Energy and Water Solutions The project is characterized by its dual focus on solar energy and water management. Photovoltaic panels are strategically placed on rooftops and parking structures, effectively capturing solar energy to power the facility and surrounding areas. Rainwater harvesting systems collect and store precipitation for irrigation, significantly reducing dependency on municipal water sources and addressing local agricultural needs.

The inclusion of substantial rainwater storage tanks is a pivotal detail, ensuring that the collected water can be utilized for irrigation, especially crucial during dry spells. The design promotes efficient water usage through containment and readily accessible distribution to community gardens, thus enhancing agricultural resilience.

Innovative Agricultural Practices Lesatsi le Pula features designated zones for urban agriculture, including raised planting beds that maximize crop yield and minimize water waste. This design encourages the cultivation of various crops, fostering food security within the community. Unique to the project is the incorporation of pedestal grazing areas, which allow for controlled grazing and promote biodiversity, illustrating a thoughtful approach to land management and sustainable farming.

The architectural layout integrates a market space adjacent to the gardens, creating a vibrant area where local farmers can sell their produce. This market not only contributes to the local economy but also strengthens community ties through social interaction. The design intentionally blurs the lines between agricultural production and community life, reinforcing the project's dual function.

Community-Centric Spaces The project emphasizes community-centric design through the inclusion of a manager's residence, providing a space for oversight of operations while ensuring comfort for personnel. The incorporation of shaded areas thanks to the solar canopies enhances usability for various community activities.

Overall, Lesatsi le Pula exemplifies a practical and adaptable architectural solution tailored to the specific needs of Gaborone. It stands out from conventional designs by prioritizing ecological sustainability, local agriculture, and community engagement.

The Mujassam Watan Urban Sculpture Challenge invites architects and designers to create iconic public sculptures for one of two sites in Saudi Arabia: Abu Hadriyah Road or the Tharwa Sea Front in Al-Khobar. Proposals should reflect Saudi identity, culture, and future aspirations.

`

The Mujassam Watan Urban Sculpture Challenge is an international architecture and design competition inviting creatives to shape the future of Saudi Arabia’s public spaces. With a total prize fund of €50,000, the competition calls for sculptural proposals that merge cultural symbolism with innovative design, offering participants a chance to see their concepts brought to life in a rapidly transforming national context.

Organised by Buildner in partnership with the Mujassam Watan Initiative, the challenge focuses on two prominent locations: Abu Hadriyah Road, a major highway and gateway into the Eastern Province, and the Tharwa Sea Front in Al-Khobar, a pedestrian-focused waterfront district. Designers must select one site and develop a sculpture that engages with its surroundings—whether addressing the fast-paced dynamism of a transit corridor or creating moments of interaction along a coastal promenade.

Proposals should be bold, site-specific, and rooted in narrative—drawing on themes such as heritage, national identity, transformation, and dialogue. Environmental responsiveness, material durability, and feasibility are strongly encouraged, as winning projects may be selected for actual construction.

Each submission must include four A2 landscape presentation boards, a cover image, and a written project description. The competition is open to professionals and students alike, working individually or in teams of up to four people. No professional license is required.

Registration is open until July 24, 2025, with final submissions due by August 27, 2025. Winners will be announced on October 1, 2025.
