Coral reefs, fish nurseries at risk in the region
By Summit Voice
SUMMIT COUNTY —A headlong development rush along the coast of Middle Eastern countries is leading to”severe loss and degradation of important habitats, including mangroves, seagrass beds, and coral reefs, in the Persian Gulf, according to a study released last week.
The report from the United Nations University Institute for Water, Environment and Health warns of potential health problems and “the permanent loss of nursery grounds for commercial shellfish and fish species,” in the fragile marine ecosystems shared by eight Gulf countries – Bahrain, Kuwait, Iran, Iraq, Oman, Qatar, Saudi Arabia, and the United Arab Emirates.
Coastal development in wealthy Gulf countries has been so extensive and swift that “there has not been enough time to develop adequate regulatory, technical, and monitoring capacity to guide this growth appropriately.”
“Though focused on the Gulf region, with its enormous new artificial islands and waterways, waterfront cities, ports and marinas, the report is relevant to other parts of the Middle East, to China, parts of South-East Asia, and elsewhere in the world where rapid coastal development is also underway,” said co-author Peter F. Sale, assistant director of the institute.
Sale said that, according to some predictions, as much as 91 percent of all temperate and tropical coasts will be heavily impacted by development by 2050.
From the report: “The physical characteristics and semi-enclosed nature of the Gulf provide ideal conditions for accumulation of pollutants and may create the ‘pollutant trap’ common in other enclosed and semi-enclosed seas. Insufficient or unreliable data exist to be able to accurately estimate the impacts of increased pollution on the Gulf’s marine environment.”
“Relatively little information exists on the short and long-term environmental effects of coastal mega-projects,” said lead author Hanneke Van Lavieren of UNU-INWEH. “Without good planning and careful consideration of existing coastal features, hydrodynamics and offshore seafloor conditions, the consequences of such developments could be severe and long lasting.”
“It is unwise to continue this pace and scale of development without careful consideration of the likely impacts on the health of marine ecosystems and their capacity to continue to provide environmental goods and services that directly support human wellbeing. If care is not taken, the economic cost of losing valuable coastal ecosystems will be extremely high.”
The report makes several recommendations:
Integrated, forward-looking management programs that protect vital coastal ecosystems, and adapt to a changing climate, while permitting economic growth and ensuring a better quality of life for all coastal dwellers.
An Environmental Impact Assessment process that is scientifically rigorous, transparent, and applied by regulatory agencies with the capacity to enforce decisions and ensure compliance by the development industry — an approach which recognizes that such assessments take time and that development must not proceed more quickly than the EIA process.
Faster scientific capacity development in the region. Over the past several years, among efforts underway by others, UNU-INWEH initiated a variety of training events in the region but substantial additional improvement is needed in terms of the number and calibre of national scientists and researchers, research institutions, available equipment and funding to sustain research and development. Greater scientific knowledge, including regional environmental databases, and greater capacity in coastal environmental management are also necessary to create sound national and regional strategies for development.
Additional legislation, at regional and national levels, directly linked to coastal development.
“Current management strategies in the Gulf are ineffective and insufficient to ensure the future health of its marine and coastal resources,” said Van Lavieren. “”Several agreements may relate in some way, but coverage is incomplete and incoherent.”
Growth in the region
Countries bordering the Gulf have an annual population growth rate of 2.1 percent, about double the world average.
Pressure on coastal ecosystems is especially high in the smaller Gulf countries of Bahrain, Kuwait, Qatar and the UAE, where residents either live entirely or almost entirely within 50 km of the coast. Some countries in the Gulf region have already developed more than 40 percent of their coastline.
Bahrain has expanded its land area by 91 km2, an 11 percent increase of its original land area, for industrial, recreational and residential purposes.
From 1999 to 2010, the coastline of Qatar doubled from 563 to 1,239 km.
In the United Arab Emirates (UAE), four man-made coastal mega-islands (Palm Jebel Ali, Palm Jumeirah, Palm Deira and The World) will add 439 km of shoreline and approximately 120 km2 of land.
Wastewater and other pollution
Untreated and unused treated wastewater is frequently dumped directly into the Gulf or riverbeds and wetlands where it then infiltrates into shallow aquifers and eventually enters coastal waters.
Enormous quantities of industrial, agricultural and domestic effluents substantially heighten the risk of contamination.
The high concentration of offshore oil installations, tankers and terminals have made the Gulf’s marine and coastal ecosystems some of the most threatened in the world by oil pollution. The region experiences “persistently high levels of hydrocarbon pollution throughout the Gulf, predominantly along the Iranian coastline.”
Meanwhile, between 70 and 90% of the freshwater supply of the Gulf’s fast-growing population depends on desalination plants, which delivers toxic brine into the Gulf.
Fisheries and reefs
Some 70 percent of the Gulf’s original 3,800 km2 reef cover is considered lost; all but 3 percent of what remains is either threatened or at a critical stage of degradation. Remaining reefs in the Gulf “are likely to degrade or disappear entirely within the next decade unless aggressive steps are taken to ameliorate the impacts of development.”
After oil and gas, fisheries represent the region’s most important natural resource, and the most important renewable resource. In the Gulf, trade in fish products accounted for US$ 996 million in 2007 and fishing (including aquaculture) employs some 250,000 people while accounting directly or indirectly for the livelihoods of 1 million residents.
Despite existing fishing regulations, poor enforcement has meant that the effort has not been controlled and many fishery species are in peril due to overexploitation.
“Inadequate enforcement of law, ineffective management practices and lack of effective trans-boundary collaboration or global catch limits all contribute to fishery failure. Given the multitude of threats facing the Gulf’s fish populations, a paradigm shift in the approach to fisheries management is needed,” says Dr. Sale.
An expanding marine aquaculture industry will place increasing pressure on already vulnerable ecosystems and native species. The fact that this industry is not yet fully developed in this region provides a unique opportunity for Gulf countries to adopt responsible and sustainable aquaculture methods. In moving forward, countries should adopt a Gulf-wide strategic and collaborative approach.
The Gulf environment is low in fish species diversity, many of which are in peril due to over-exploitation, pollution and the introduction of invasive species. Further environmental degradation and habitat loss caused by coastal development are compounding this threat.
The highly populated and predominantly sandy, easily erodible and low lying coastal Gulf countries are especially vulnerable to the impacts of sea level rise through direct inundation, erosion and salt water intrusion. Studies predict that most of the Gulf’s coastal areas will be extensively inundated and large parts of shorelines will migrate inland; Qatar and the UAE will be particularly susceptible and other small Gulf countries (Bahrain and Kuwait) are also at risk.
The report urges Gulf countries to take urgent action to prepare for the potential impacts of climate change on coastal areas and resources, including adoption of national energy efficiency and renewable energy targets, promotion of the ‘green building’ concept and development and use of alternative and renewable energy sources. Furthermore, increased scientific knowledge and greater capacity within the field of climate change is needed to create sound national and regional strategies for adaptation which in turn are incorporated into national and regional development plans.
