Water Problems and Solutions in the Wake of International Day of Biodiversity 2013

Water is the key to biological diversityWater is synonymous with biological diversity. The UN’s International Day for Biological Diversity (IBD) is celebrated each year on May 22nd, it is designed to increase awareness of biodiversity issues. The theme for IBD 2013 was Water and Biodiversity and its goal was to raise awareness about the mutually reinforcing relationship between water security and biodiversity.

From its creation by the Second Committee of the UN General Assembly in 1993 until 2000, IBD was held on December 29 to celebrate the day the Convention on Biological Diversity (CBD) went into effect. The date was later changed to commemorate the adoption of the CBD on May 22, 1992 at the Rio Earth Summit.

Providing water access is a major challenge for sustainable development. Only a tiny amount of the water on our planet is easily available as freshwater and demand is increasingly outpacing supply.  In the U.S., the issue of water scarcity is widespread with two-thirds of the country suffering from extreme drought last summer. The UN estimates that 1.2 billion people or almost one fifth of the world’s population live in areas of physical scarcity.

Arctic Ocean Rapidly Acidifying

Arctic oceans acidification is increasing rapidly due to several factors including declining sea ice and freshwater flows. After three years of ongoing research by an international team of scientists, a study commissioned by the Arctic Monitoring and Assessment Programme for a first-ever comprehensive assessment of Arctic Ocean acidification was presented last week at a meeting of Arctic Council Ministers in Bergen, Norway.

The research show that the cold waters of the Arctic sea are more vulnerable to acidification. Cold water more readily absorbs CO2 and combined with the precipitous drop in summer sea ice extent, thus exposing more open water, northern oceans are rapidly acidifying.

“The sea ice has been a lid on the Arctic, so the loss of ice is allowing fast uptake of CO2,” said Richard Bellerby of the Norwegian Institute for Water Research, chairman of the report.

EarthTalk: Climate Change and Hawaii’s Coral Reefs

Poisonous run-off, rising ocean levels, increasingly acidic waters and overfishing are taking their toll on Hawaii's reefs and the marine life they support. Biologists are working hard to stem the problem but must now deal with invasive algaes that are compromising the whole reef system.EarthTalk® is a weekly environmental column made available to our readers from the editors of E/The Environmental Magazine

Dear EarthTalk: What’s the prognosis for Hawaii’s coral reefs in the face of global warming, invasive algae and other environmental threats?  – Bill Weston, San Francisco, CA

Despite sweeping protections put in place near the end of George W. Bush’s presidency for large swaths of marine ecosystems around the Hawaiian Islands, things are not looking good for Hawaii’s coral reefs. Poisonous run-off, rising ocean levels, increasingly acidic waters and overfishing are taking their toll on the reefs and the marine life they support. Biologists are trying to remain optimistic that there is still time to turn things around, but new threats to Hawaii’s corals are only aggravating the situation.

Obama Administration Issues First National Climate Adaptation Strategy

The Obama administration set forth a national climate adaptation strategy

Source: US Fish, Wildlife, and Plants Climate Adaptation Strategy

Marking a milestone in US environmental and natural resource management policy, the Obama Administration on March 26 released a national strategy aimed at conserving, enhancing the resiliency, and making sustainable use of the nation’s natural resources in the face of climate change.

Drawing on input, resources, and expertise of federal, state, and tribal government agencies as well as non-profit sector organizations and the American public, the National Fish, Wildlife, and Plants (NFWP) Climate Adaptation Strategy, “provides a unified approach – reflecting shared principles and science-based practices – for reducing the negative impacts of climate change on fish, wildlife, plants, and the natural system upon which they depend.”

Developing US Offshore Wind Energy: BOEM Seeks Interest in Offshore NY Wind Farm

UK's Thanet Wind Farm: Will the US follow suit of other countries in development of offshore wind? Driven forward by Obama Administration actions on energy policy, the US is finally beginning to try to tap into and harness the tremendous clean and renewable energy of its offshore ocean winds and waters in earnest. On January 3, the Bureau of Ocean Energy Management (BOEM) announced it is seeking to determine whether or not there’s competitive interest in leasing an area offshore New York that the New York Power Authority (NYPA) has proposed as a site for an offshore wind power farm. The request also seeks to gather public comments on the proposed project’s environmental impacts and consequences and how the area is being used at present.

The Bureau of Ocean Energy Management BOEM, along with the Bureau of Safety and Environmental Enforcement (BSEE), is at the core of US offshore renewable energy development efforts. They were created as part of a major organizational overhaul that saw the end of the troubled Minerals Management Service (MMS). Read More→
