West Environmental, Inc. together with Carex Ecosystem Sciences and Doucet Survey, under contract with the NH Estuaries Project, have identified and mapped potential freshwater wetland mitigation opportunities in nineteen (19) communities that border coastal or estuarine habitats

Dynamics of Tipping Cascades on Complex Networks

Tipping points occur in diverse systems in various disciplines such as ecology, climate science, economy or engineering. Tipping points are critical thresholds in system parameters or state variables at which a tiny perturbation can lead to a qualitative change of the system. Many systems with tipping points can be modeled as networks of coupled multistable subsystems, e.g. coupled patches of vegetation, connected lakes, interacting climate tipping elements or multiscale infrastructure systems. In such networks, tipping events in one subsystem are able to induce tipping cascades via domino effects. Here, we investigate the effects of network topology on the occurrence of such cascades. Numerical cascade simulations with a conceptual dynamical model for tipping points are conducted on Erd\H{o}s-R\'enyi, Watts-Strogatz and Barab\'asi-Albert networks. Additionally, we generate more realistic networks using data from moisture-recycling simulations of the Amazon rainforest and compare the results to those obtained for the model networks. We furthermore use a directed configuration model and a stochastic block model which preserve certain topological properties of the Amazon network to understand which of these properties are responsible for its increased vulnerability. We find that clustering and spatial organization increase the vulnerability of networks and can lead to tipping of the whole network. These results could be useful to evaluate which systems are vulnerable or robust due to their network topology and might help to design or manage systems accordingly.Comment: 22 pages, 12 figure

Recommendations of Alternative System Plans and Transmission Corridors for the Dickey/Lincoln School Hydroelectric Project

The regional scope of this study (a three state area of approximately 33,000 square miles) necessitated an initial investigation to determine what data was available. Known and potential sources of data were identified through the use of the Environmental Data Reconnaissance Report* prepared by Comitta Frederick Associates for the United States Depart-ment of the Interior in March 1976. The collected data was then analyzed for its accuracy, reliability, mappability and compatibility with the scope of this study

Agronomic evaluation of biofortified beans in Antioquia producers’ farms

The objective of this research was to evaluate genotypes of iron- and zinc-enriched common beans during breeding in producers’ farms. Yield, disease reaction, and commercial grain characteristics were evaluated to achieve this objective. In three locations of Antioquia (Rionegro, Jardín, and Betulia), seven bush beans and eight climbing bean genotypes were planted. A randomized complete block design with four replications was used in each location. There were significant differences between the bush and climbing bean genotypes that were evaluated. The highest yields, in all locations, were for the biofortified bean NUA 45 and the control variety Uribe Rosado, followed by the CAL 96 and AFR 612 genotypes. For the climbing beans, the highest yields were found in the G2333 genotypes, being this treatment equal to the MAC 27, a bean that is adapted to mid-climate and altitudes. The MAC 27 material is presented as a promising variety because of its high yields and tolerance to diseases, mainly anthracnose

Recommendations of Alternative System Plans and Transmission Corridors for the Dickey/Lincoln School Hydroelectric Project

This second volume of the Assessment of Alternative Power Transmission Corri-dors related to the Dickey Lincoln/School Hydroelectric Project, contains all relevant background materials to support the mapping and analysis of en-vironmental resource information. Narrative explaining what information was evaluated and the sources and reasons for its consideration are integral to this assessment

NATIONAL INSTITUTE OF ENVIRONMENTAL HEALTH SCIENCES HEALTH DISPARITIES STRATEGIC PLAN

Health disparities exist between citizens of lower socioeconomic status (including minorities and other medically underserved citizens) and those more economically advantaged. Examples where health disparities exist include: shorter life expectancy, higher cancer rates, more birth defects, greater infant mortality, and higher incidence of asthma, diabetes, and cardiovascular disease. These health discrepancies involve increased morbidity and mortality rates associated with increased incidences of disease. The ways in which poverty and other factors create these health disparities are still poorly understood. There is increasing evidence that these groups are burdened with a disproportionate share of residential and occupational exposure to hazardous substances such as lead, PCBs, wood dusts, and air pollutants. Thus, both social and physical environmental exposures represent an important area of investigation for understanding and ameliorating the health disparities suffered by the disadvantaged of this nation

Signal detection in global mean temperatures after "Paris": An uncertainty and sensitivity analysis

In December 2015, 195 countries agreed in Paris to hold the increase in global mean surface temperature (GMST) well below 2.0 °C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 °C. Since large financial flows will be needed to keep GMSTs below these targets, it is important to know how GMST has progressed since pre-industrial times. However, the Paris Agreement is not conclusive as regards methods to calculate it. Should trend progression be deduced from GCM simulations or from instrumental records by (statistical) trend methods? Which simulations or GMST datasets should be chosen, and which trend models? What is pre-industrial and, finally, are the Paris targets formulated for total warming, originating from both natural and anthropogenic forcing, or do they refer to anthropogenic warming only? To find answers to these questions we performed an uncertainty and sensitivity analysis where datasets and model choices have been varied. For all cases we evaluated trend progression along with uncertainty information. To do so, we analysed four trend approaches and applied these to the five leading observational GMST products. We find GMST progression to be largely independent of various trend model approaches. However, GMST progression is significantly influenced by the choice of GMST datasets. Uncertainties due to natural variability are largest in size. As a parallel path, we calculated GMST progression from an ensemble of 42 GCM simulations. Mean progression derived from GCM-based GMSTs appears to lie in the range of trend–dataset combinations. A difference between both approaches appears to be the width of uncertainty bands: GCM simulations show a much wider spread. Finally, we discuss various choices for pre-industrial baselines and the role of warming definitions. Based on these findings we propose an estimate for signal progression in GMSTs since pre-industrial
