Risk, Vulnerability, and Hazards: The Industrial Canal and the Lower Ninth Ward

The purpose of this study is to identify, analyze, and describe the social outcomes that may be affected by the environmental risks generated by infrastructure projects; to examine the ways in which vulnerability and exposure to hazards may increase risk in neighborhoods over time; and to examine the implications of addressing the exacerbation of exposure to natural hazards within the traditional environmental justice framework. The Industrial Canal and Lower Ninth Ward were selected as the subjects of this case study because the canal has existed on the perimeter of the neighborhood for nearly one century, isolating Lower Ninth Ward residents from the rest of New Orleans and significantly contributing to two catastrophic flood events. The findings of the study are as follows: (1) the environmental risks associated with infrastructure projects can be magnified when imposed on an already vulnerable neighborhood, and may ultimately result in hazard events which cause displacement and disinvestment. Such consequences can have an impact on micro-level (individual and household) and macro-level (neighborhood) social outcomes; (2) vulnerability and exposure to hazards can initiate a pattern of increased risk that intensifies vulnerability to subsequent hazard events; and, finally, (3) the parallels between the causes and consequences of traditional environmental justice issues and the exacerbation of exposure to natural hazards implies that framing issues relative to natural hazards as matters of justice and articulating the social consequences of not mitigating such hazards can be an excellent way of educating stakeholders and lobbying for resources

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

The Arctic Coastal Dynamics database. A new classification scheme and statistics on arctic permafrost coastlines

Arctic permafrost coasts are sensitive to changing climate. The lengthening open water season and the increasing open water area are likely to induce greater erosion and threaten community and industry infrastructure as well as dramatically change nutrient pathways in the near-shore zone. The shallow, mediterranean Arctic Ocean is likely to be strongly affected by changes in currently poorly observed arctic coastal dynamics. We present a geomorphological classification scheme for the arctic coast, with 101,447 km of coastline in 1,315 segments. The average rate of erosion for the arctic coast is 0.5 m year(-1) with high local and regional variability. Highest rates are observed in the Laptev, East Siberian, and Beaufort Seas. Strong spatial variability in associated database bluff height, ground carbon and ice content, and coastline movement highlights the need to estimate the relative importance of shifting coastal fluxes to the Arctic Ocean at multiple spatial scales
