Poor Coastal Development

Hurricane Katrina Destruction View Hurricane Katrina and Ike Gallery

Developed coasts change natural beach processes. Even a single building alters natural movement of wind which can disrupt sand transport, movement of rainwater runoff, and negatively impact plants and animals. Aesthetically, development reduces the quality of visits by tourists and once development begins, more follows. The long history of beach development in Europe and the northeastern United States has resulted in heavy modification of, and in some cases total destruction of, natural beaches.

Development on coasts is in grave danger in the coming decades from the combination of sea level rise and storms. When coastal development is built too close to the shore, the results can be devastating as evidenced by recent hurricanes Ike and Katrina in the United States. Two simple concepts must be followed:

  1. Do not build a house that will be underwater in the next 50 years and
  2. Do not build a house that will be knocked down by a storm.

These two basic principles are seldom followed today and when they are not, the costs can be human lives and billions of dollars.

After a large storm strikes, rebuilding is often financed with public money. Once a coastal community has been developed, rebuilding efforts often focus on putting things back the way they were rather than making objective decisions about changes that need to be made based on the rising sea. Developed coastlines need to retreat from the coast to allow the beach to move. Coastlines are dynamic, but buildings are not. More information on this topic can be found at the website of The Program for the Study of Developed Shorelines at Western Carolina University in Cullowhee, North Carolina, USA.

White sand, black gold: when oil derricks loomed over California beaches

As California population boomed in the decades following the gold rush of 1849, there was a rapidly growing demand for petroleum. By 1920, California was producing 77 million barrels of oil a year, and vast stretches of the state were occupied by derricks, and refineries. In coastal places such as Venice, oil derricks ran right up to the shore, mingling with residential neighborhoods and pristine beaches.

Chennai floods are not a natural disaster, Tamil Nadu, India

As a city on the high-energy coast facing the Bay of Bengal, Chennai is no stranger to heavy rains and cyclonic storms. But with every invitation to “Make in Chennai”, the city is unmaking itself and eroding its resilience to perfectly normal monsoon weather events. The infrastructure of big commerce has replaced the infrastructure to withstand natural shocks.

‘Repetitive Loss’ Properties Raise Debate Over Rebuilding After Floods

Throughout Connecticut, thousands of homes have suffered: repetitive loss, as FEMA calls it, from flooding. Many residents have rebuilt multiple times. And many, also have used government funds from an alphabet soup of federal programs and agencies to do some, if not all, of the work. But shoreline and climate experts, public officials and others have grown increasingly critical of such programs.

Disappearing Beaches of India

Beaches and coasts are amazing wonders of nature. India’s coastline stretches for around 7,500 kilometers. Yet, as much as 40% of India’s coastline is eroding at an alarming level, not only in Tamil Nadu and Puducherry, but also in many other beaches.
