Happy New Year !!!

I try to keep this space professional, so I won't share my personal New Year's resolutions or predictions.  But, my law prof blogging intentions (note: not resolutions) are to:

(1) add resources

(2) blog more commentary

(3) blog more consistently

That's enough...I've always tried to follow the tennis pro's 3 tips rule.

One additional change I plan to make is to direct future royalties towards international projects promoting sustainable drinking water and sanitation in developing countries.

Biodiversity science: Invasive Species Dynamics

Invasive species are second only to habitat destruction in causing loss of biodiversity.  However, scientists have found it difficult to prevent the spread of invasive species because spread dynamics are poorly understood. A study by Arim, et al., was published yesterday in the Proceedings of the National Academy of Science suggests that the spread of invasive species is not idiosyncratic and follows general patterns. PNAS Abstract

Species invasions are a principal component of global change, causing large losses in biodiversity as well as economic damage. Invasion theory attempts to understand and predict invasion success and patterns of spread. However, there is no consensus regarding which species or community attributes enhance invader success or explain spread dynamics. Experimental and theoretical studies suggest that regulation of spread dynamics is possible; however, the conditions for its existence have not yet been empirically demonstrated. If invasion spread is a regulated process, the structure that accounts for this regulation will be a main determinant of invasion dynamics. Here we explore the existence of regulation underlying changes in the rate of new site colonization. We employ concepts and analytical tools from the study of abundance dynamics and show that spread dynamics are, in fact, regulated processes and that the regulation structure is notably consistent among invasions occurring in widely different contexts. We base our conclusions on the analysis of the spread dynamics of 30 species invasions, including birds, amphibians, fish, invertebrates, plants, and a virus, all of which exhibited similar regulation structures. In contrast to current beliefs that species invasions are idiosyncratic phenomena, here we provide evidence that general patterns do indeed exist.

Wetlands: The Large/Small Handle Issue

Last month, in an interesting take on the large handle/small handle issue, the federal district court in the Southern District of Florida enjoined the Corps from issuing a CWA 404 permit based on inadequate NEPA compliance.  The Corps had analyzed only the effects of the filling of the 20+ acres of jurisdictional wetlands and not the cumulative and synergistic impacts of the development of the 1900+ acre biotechnology park proposed by Scripts Research Institute.  Florida Wildlife Federation v. Corps, 2005 WL 3418302 (S.D.FL 2005).

Judge Redden Refuses to Substantially Change Proposed Columbia River Hydro Operations During 2006

Today, Judge James Redden issued an opinion and order in NWF v. NMFS largely refusing to change the planned operations of the Columbia River hydro system with respect to spill and flow augmentation.  Judge Redden's opinion gave the federal government deference on every close issue. 12/30 Opinion on Injunctive Relief Pending Columbia River BiOp Remand

Ecological economics: sustaining optimal growth

Those interested in sustainable development may want to consider a paper recently published by Simone Valente of the Institute of Economic Research ETH Zurich, entitled "Sustainable Development: Renewable Resources and Technological Progress." Valente Paper  As should be obvious, growth in per capita consumption cannot be sustained for exhaustible natural resources (Pezzey and Withagen 1998).  Valente extends the model to include technical progress, resource renewability, extraction costs and population growth, with the result that optimal growth paths can only be maintained if the social discount rate does not exceed the sum of the rates of resource regeneration and augmentation. The development of resource-saving techniques is crucial for sustaining consumption per capita in the long run, whereas capital depreciation and extraction costs do not affect sustainability.

Regional Greenhouse Gas Initiative

Although Massachusetts and Rhode Island did not sign, last week seven Northeastern states signed a memorandum of understanding pledging to reduce greenhouse gas emissions.  Connecticut, Delaware, Maine, New Hampshire, New Jersey, New York, and Vermont have agreed to cut CO2 emissions by 2.5 % annually beginning in 2015, for a total reduction of 10% below 2009 projected levels by 2019. 

The states participating in the RGGI will issue allowances for each ton of CO2 emitted by power plants.  Each plant producing 25 MW or more must have enough allowances to cover its individual carbon dioxide emissions and meet a specific cap placed on total emissions.  Plants may sell their excess allowances to companies that need to offset higher emissions, buy allowances from the 25% of total allowances retained by the states, or use "offsets" from projects that reduce GHG emissions such as landfill methane gas recovery, reforestation, and methane capture efforts from farming or natural gas transmission facilities.

A safety valve allows states to extend compliance periods for plants if the cost of CO2 allowances reaches $10 and allows plants to use offsets in lieu of allowances for up to 20% of their emissions. 

The 2009 projected emissions used to establish allowances are: New York: 64,310,805 short tons; New Jersey: 22,892,730 short tons; Connecticut: 10,695,036 short tons; New Hampshire: 8,620,460 short tons; Delaware: 7,559,787 short tons; Maine: 5,948,902 short tons; Vermont: 1,225,830 short tons.

Insured losses from Hurricanes Katrina, Rita, and Wilma estimated at almost $ 60 billion

Planet Ark reported today that Advisen Ltd. estimates worldwide insurance and reinsurance losses related to the three major hurricanes that hit the United States this year to be $57.6 billion, making the cumulative catastrophe losses the largest on record. Including unreported/unfiled losses,
Advisen projects pre-tax insured losses per hurricane to be $40.4 billion for Katrina, $6.4 billion for Rita, and $10.8 billion for Wilma. The losses amount to more than twice the annual total for other US natural disasters and one-and-a-half times the losses from the 2001 terrorist attacks in New York and Washington.  Several variables could prompt Advisen's estimates to increase dramatically, the company warned. Flood losses could elevate Advisen's estimates by billions of dollars if lawsuits to force insurers to cover flood damage related to Hurricane Katrina are successful. Also, hurricane-related pollution lawsuits could add hundreds of millions to Advisen's totals.

Disaster Planning

<>

John Bohannon notes in Science that the last year has been one of unprecedented natural disasters -- the 2004 "Christmas tsunami" in the Indian Ocean, Hurricane Katrina on the U.S. Gulf Coast, and the Pakistan earthquake, which left nearly 300,000 dead and millions homeless.

Natural disasters are anything but natural: societies can mitigate their impacts by making the right decisions about where and how people live, how information is shared, and what kind of research to invest in.

Some ideas include:

  • Disaster mitigation consultant Aromar Revi's proposal for "a public database like Google Earth" that would allow researchers around the world to map the "risk landscape down to the ZIP-code level." Nations with shared risks could build better warning networks -- if they are willing to share data and the expense.
  • <>

    Economist Reinhard Mechler's proposal for nations to use the disaster insurance market to improve risk-sharing, rather than rely on international charity  -- which would require the same sort of detailed risk data.


  • <>

    the US National Science and Technology Council's call for enhanced interdisciplinary communication as well as social science research to aid emergency risk communication

    As he notes:

One thing is all but certain: Even worse years lie ahead. Vulnerable urban populations of the developing world are set to double by 2030, as are coastal populations everywhere. Meanwhile, changing climate threatens to bring more hurricanes due to warming and chronic coastal flooding due to rising sea levels, among other worrying possibilities.

Science's 2004 Prediction on Nanotechnology Regulation on Target

Scientific Breakthrough of the Year 2005: Climate change is a runner-up

As Science said:

The new science was much like that of the past decade, just more insistent and more ominous. In January, climate modelers announced even higher confidence in earlier assertions that the oceans--down to great depths--have warmed in recent decades just as models said they would. Each of two tropical cyclone studies found that over recent decades more and more storms around the world have grown to the most intense levels as rising greenhouse gases have warmed tropical waters. At higher latitudes, scientists announced, Arctic Ocean ice cover had hit another record low, this time with the added warning that the feedbacks expected to accelerate high-latitude warming--and presumably ice loss--seem to be taking hold. And all this climate change is having an effect. It's altering everything from bird migration patterns in Australia to microbial compositions in sea-floor muck.
