The Portugal Pavilion at Expo 2025 in Osaka embraces the theme "Ocean, The Blue Dialogue", offering visitors an immersive exploration of the ocean as a life-giving resource and a cornerstone of sustainability. Designed by Japanese architect Kengo Kuma, the Pavilion aims to reflect Portugal's deep historical, cultural, and economic connections to the sea, creating an architectural and narrative journey that bridges past, present, and future.
At the initiative of the Surf Ghana Collective, architects Glenn DeRoché and Jurgen Strohmayer, the co-founders of DeRoché Strohmayer, set out to transform a small waterfront plot in Busua, a surfing hotspot on Ghana’s western coast. The result is a dynamic community hub, complete with amenities for local surfers, but also providing spaces for the entire community to gather in and off-season. The project has been recognized as the winner of the Gold Prize of Holcim Awards 2023 for the Middle East and Africa commended for the profound local impact and the resourceful approach to construction techniques. In a video interview for ArchDaily, architects Glenn DeRoché and Jurgen Strohmayer discuss the development of this initiative and the innovations that shaped it.
Land reclamation from the sea has become a popular phenomenon in coastal development. It is the most preferred solution to the need for land in coastal areas and has been implemented for various use cases, including flood control and agriculture. Nowadays, it has become a famous urban response to the rapid increase in coastal urbanization, economic activity, and global population. Countries like China and the Netherlands lead the chart on the amount of land area reclaimed. However, most reclamation projects today take place within urban centers in the global south. Cities in West Africa, East Asia, and the Middle East produce these new lands as economic forerunners for their commercial industry and as platforms to house luxury residences.
But the relationship between the design and production of reclaimed lands and the response of water in ocean environments is complex. It requires a symbiotic relationship with water bodies for stability but can provoke natural forces when negligently imposed on the sea. Ocean water behaviors, including tidal accumulation, sea level rise, connection to wetlands, and aquatic biodiversity, can question the success or failure of land reclamation projects in different contexts.
