The health, beauty and ecosystem of our beaches is under threat
The driving cause for most of these problems is overdevelopment and poor coastal management. If no buildings crowded the shoreline, there would be no shoreline armoring, beach nourishment, threats to the beach fauna and flora or shoreline erosion problems.
Coastal Care Introduction
“Beach sand: so common, so complex, so perfect for sandcastles; and now it is a precious and vanishing resource.”—Orrin H. Pilkey
Beaches are the most visited natural attraction on the planet. The coast attracts millions of vacationing people each year. People love the sand, the surf, the sea breeze, and the vacation ambiance so much that many come to the beach to stay. There is a magical feeling living near the ocean, but human migration towards the coast comes with a high environmental price tag.
A majority of the world’s population lives within 50 km of the coast and the projections are 75% by the year 2025. This strip of land represents only 3% of the total land mass of the planet. In this context, it is easier to understand the environmental impact. Over 70% of the earth is covered by water and with so many people living on the coast, we are polluting a major source of food, the oceans.

The loss of life and economic impacts of major storms – cyclones, typhoons, and hurricanes – and tsunamis would be reduced drastically if beaches were not developed. Unfortunately, recent examples of the problem are numerous: 1999 Indian cyclone Orissa (over 10,000 dead and $5 billion in damage), 2004 Indian Ocean tsumani (over 250,000 dead), 2005 Hurricane Katrina (over 1,800 killed and $80 billion in damage), and 2008 Hurricane Ike (over 30 killed and $30 billion in damage).
Today, the health, beauty, and ecosystem function of the world’s beaches are under threat and the driving causes for most of these problems are over-development and poor coastal management. If no buildings crowded the shoreline there would be no shoreline armoring, beach nourishment, threats to the beach fauna and flora or shoreline erosion problems.
It is important to distinguish between erosion and erosion problems. Erosion refers to the landward retreat of the shoreline. Most of the world’s shorelines are eroding, a very few are building out (accreting). There is no erosion problem, however, until someone builds something next to a shoreline. All over the world in remote areas, shorelines are slowly retreating and no one cares. In a global sense, our continents are slowly shrinking, and in a very real sense, erosion problems are man made. On a high-rise, condo-lined shoreline like those in Spain and the Florida coast, erosion is a huge problem and will only worsen in the future as sea level rise accelerates. Sea level rise will accelerate erosion of the shoreline and have a dramatic impact on our infrastructures, our economies, and our way of life.
Sea level rise is one of the most important causes of global shoreline erosion. If the coastline is developed, shoreline armoring is often used in an effort to save the buildings from the eroding shoreline. Once this begins, the beaches will degrade and eventually be lost. In the long-term, however, these armoring efforts are in vain. The ocean will continue to rise as the rate of sea level rise is expected to increase as the Greenland and Antarctic ice sheets continue to degrade. The situation is made worse now because beach houses and condominiums are being built closer to the ocean than they were 25 years ago. Many of us are familiar with images of large beach houses about to fall victim to the oceans simply from daily erosion accelerated by the ever rising sea.
The work of the Santa Aguila Foundation will emphasize the impacts of sand mining and shoreline armoring: the first because the effects of sand mining have been largely ignored on a global scale and the latter due to its overwhelming negative impacts on the world’s beaches.

As strange as it may sound, sand is one of the world’s hottest commodities. The global construction boom has created an insatiable appetite for sand, the chief ingredient for making concrete. The problem is that sand isn’t as abundant as it used to be. And when high demand and high value meets scarcity, you open the doors to smuggling.

The Red Sea is one of the world’s saltiest and warmest seas. It is an extremely harsh environment surrounded by desert and subject to very high temperatures. However, there has been no decline in mangrove stands in the Red Sea, where the extreme conditions seem to mean that the mangroves of the Red Sea have been subjected to much lower levels of human activity than elsewhere.

The U.S. Environmental Protection Agency announced it will no longer ask oil and gas well operators to submit information about their equipment or methane emissions. Methane is short-lived, but powerful greenhouse gas. Over the short term, it can trap heat at least 30 times more efficiently than carbon dioxide, and is thought to be responsible for about a quarter of modern global warming.

In Kenya, as in most of the developing world, cities are growing at a frenzied pace. Creating buildings to house all the people and the roads to knit them together requires prodigious quantities of sand. As the price of sand goes up, the ‘mafias’ get more involved.

The Lapis Sand Plant, in operation since 1906, is the nation’s last coastal sand mine. The California Coastal Commission has threatened to close the plant, but the company refuses to relinquish its claim to the uniquely coarse amber-colored Monterey sand, which it calls “Lapis Lustre.” But Cemex is the world’s second largest building materials company, and any attempt to kick it out is likely to immerse the state in years of expensive litigation.

Cost-effective solutions to sediment runoff and other land-based pollution affecting West Maui reefs
Land-based pollutants have been linked to the degradation of several Hawaiian reefs. Between 2000 and 2015, coral cover on West Maui’s northern reefs has dramatically declined from 30 percent to 10 percent.
