Sustainable Coastal Development

Coastlines are where the sea meets land. While they always played an important role in human history, they have increasingly become one of the most desirable living places on the planet. People chose to live near the water for various reasons: a fairly moderate climate influenced by coastal winds, and year-round access to leisure, fishing, and ports for navigation and transportation of goods. For many, the deciding factor evolves around the lifestyle coastal environments provide. In recent decades, affluent urbanites and retirees have begun to move to small existing coastal towns or newly created communities in their search for beautiful, natural surroundings. Recent research, suggesting that people who live closer to the coast are in better health, has only strengthened its appeal.

Sustainability and resilience are becoming increasingly relevant in coastal development. While the concept of sustainability has been around since the 1990s, resilience is a relatively new concept: it represents a holistic, anticipatory and proactive approach that values adaptability to change.

Change is constant and inevitable, and we are witnessing the beginnings of some dramatic changes related to temperature and sea level rise. In fact, we can observe the effects already, including an increase in daily temperatures, change in rainfall patterns and extreme weather events, sea level rise, increase in sea surface temperature, changes in hydrology, and loss of biodiversity. The associated impacts will be felt sooner than originally anticipated and will affect the return on the investments made in the coming years. Sea-level rise threatens low-lying shores, especially those in storm paths, but even rugged coasts may experience significant changes in weather patterns. Resulting economic costs and damages to resorts, airports, local tourism, etc. in the Caribbean alone are estimated to exceed 20 billion dollars (US) per year. By contrast, proactive adaptation is far less expensive, with $1 in adaptation preventing $4 in economic losses.

Adaptation means to create coastal built environments that can withstand higher seas and stronger storm surges through sensible choices in terms of siting, setbacks and elevations. With regard to infrastructure such as energy, water, and wastewater treatment, it appears advantageous to employ more decentralized, smaller and flexible systems that can be repeatedly adapted over time to the changing physical conditions of coastal environments. Research and education are useful tools to develop adaption measures related to land use, changes in hydrology, exposure to tropical vector diseases, seal level rise, extreme weather events, biodiversity and ecosystems (just to name a few) that will result in sustainable and resilient costal developments.

The development of coastal areas will continue to be a desirable undertaking simply by virtue of location, but it is imperative for the future of the planet and our own sake as people to create coastal environments that are resilient, sustainable and economically viable.

Living on the Coast

Nearly 60% of the world’s population lives and works within 100 km of the coast, and a majority of metropolises with a population of more than 2.5 million, are situated at the edge of the sea. People chose to live near the water for various reasons: a fairly moderate climate influenced by coastal winds, and year-round access to leisure, fishing, and ports for navigation and transportation of goods. For many, the deciding factor evolves around the lifestyle coastal environments provide. In recent decades, affluent urbanites and retirees have begun to move to small existing coastal towns or newly created communities in their search for beautiful, natural surroundings. Recent research, suggesting that people who live closer to the coast are in better health, has only strengthened its appeal.

Undoubtedly, the largest influence on coastal development can be traced back to tourism, which represents the world’s largest service industry, supporting 1 in 12 jobs globally and generating $6.5 trillion every year. International travel has increased 40-fold since 1960 and surpassed 1 billion travelers in 2012, with many tourists spending time on the beach, or on the water. In fact, 12 of the 15 top international destinations are countries with coastlines. Sand, sun and sea tourism makes for the largest and most lucrative sector of the tourism industry.

In response to the increasing demand, coastal areas across the globe have seen a great deal of urban and resort development, including large, all-inclusive resorts, small upscale boutique hotels, eco-lodges, marinas, residential (second) homes, and commercial areas. Naturally, these developments often raise environmental and socio-cultural issues, including the modification of the natural landscape, competition for scarce resources, rising real estate prices, potential loss of distinctive character, the displacement of local fishing and farming communities, and the outright destruction of natural jewels, such as mangroves and coral reefs. The promise to create sustainable and resilient developments too often remains unfulfilled, quickly leading to increasing resistance from coastal communities and other stakeholders. Given the diverse ecosystem services coastal systems provide, these conflicts between utilization versus protection are bound to arise, and add to the already existing challenges, from water scarcity, resource shortages and climate change, to social inequities that threaten to destroy the social fabric of many of our communities.

Change is evitable, negative outcomes aren’t. In the past, little if any consideration was given to the importance of the natural and socio-cultural systems in coastal areas that already existed in areas under consideration for new real estate and tourism development projects.

It is encouraging that one of the world’s leading planning and design firms, EDSA in Fort Lauderdale, has begun to develop and employ a more research-based and performance orientated approach that emphasizes sustainability and resiliency when shaping the future of our coastlines.

Because we all depend on a healthy ocean; a healthy ocean depends on us.
