“…These classes of land cover serve as significant carbon sinks and play a key role in global climate change mitigation, so disruption form oil spills at the scale observed in this study can have major implications beyond the region. Mangroves and rainforests are known to provide other significant ecosystems services in the context of hydrological and nutrient cycling but they also provide valuable habitat for the wide range of floral and faunal species, many of which are endemics within the Niger Delta (Mendoza-Cant et al, 2011;Ndidi et al, 2015). The magnitude of the impacts of oil spills on mangroves and rainforests that have been revealed in the present study demonstrate the severe and ongoing threat that is being presented to sustainability of these sensitive ecosystems.…”

The Niger Delta is one of the largest oil producing regions of the world. Large numbers and volumes of oil spills have been reported in this region. What has not been quantified is the putative exposure of humans and/or the environment to this hydrocarbon pollution. In this novel study, advanced geostatistical techniques were applied to an extensive database of oil spill incidents from 2007 to 2015. The aims were to (i) identify and analyse spill hotspots along the oil pipeline network and (ii) estimate the exposure of the hydrocarbon pollution to the human population and the environment within the Niger Delta. Over the study period almost 90millionlitres of oil were released. Approximately 29% of the human population living in proximity to the pipeline network has been potentially exposed to oil contamination, of which 565,000 people live within high or very high spill intensity sectors. Over 1000km of land has been contaminated by oil pollution, with broadleaved forest, mangroves and agricultural land the most heavily impacted land cover types. Proximity to the coast, roads and cities are the strongest spatial factors contributing to spill occurrence, which largely determine the accessibility of sites for pipeline sabotage and oil theft. Overall, the findings demonstrate the high levels of environmental and human exposure to hydrocarbon pollutants in the Niger Delta. These results provide evidence with which to spatially target interventions to reduce future spill incidents and mitigate the impacts of previous spills on human communities and ecosystem health.

“…Although petroleum is the most important energy and raw material source for various synthetic chemicals, its use always involves a considerable risk of oil spillage that could occur during its transportation and storage . Oil spills in land, river, or ocean environments impose a major threat on the environment, because they have a severe impact on the environment, marine life, and industries such as the food and tourism trades …”

A magnetic resin based on cardanol, furfural, and curaua fibers was prepared and characterized. The material could be used in oil‐spill cleanup processes, because of its aromatic/aliphatic balance. The resin was prepared through bulk polycondensation of cardanol and furfural in the presence of curaua fibers and maghemite nanoparticles. Hydrophobicity of the curaua fibers was improved by acetylation, increasing the oil‐absorbing capability of the composites. The obtained magnetic composites were studied by Fourier‐transform infrared spectroscopy, X‐ray diffraction, and thermogravimetric analysis. Degree of cure, magnetic force, and oil‐removal capability tests were also performed. The results show that the composites possess an elevated cure degree in addition to a considerable magnetic force. The materials exhibit a good oil removal capability in the presence of a magnetic field, which is improved by the use of acetylated curaua. In the best case, the composite filled with maghemite and curaua can remove 12 parts of oil from water. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 41732.

“…A coral reef corridor lies close to the shore along the southwestern Gulf of Mexico, with coastal lagoons, mangroves, and towns in the state of Veracruz, Mexico. Human activities along this coastline depend on fishing, tourism, oil, gas and commercial pier activities (Jordán-Dahlgren and Rodríguez-Martínez, 2003;Tunnell et al, 2007;Jiménez-Badillo, 2007;Mendoza-Cantú et al, 2011). Yet, ecosystems' functions are threatened, among other forcing factors, by the effects of climate change driving extreme climatic events (Moberg and Folke, 1999;Hoegh-Guldberg et al, 2007), threatening also the lives of over seven million people along the coastline (INEGI, 2010).…”

RESUMENLas tendencias climáticas locales y regionales impulsarán las tasas de cambio en los ecosistemas costeros. Se caracterizaron series temporales de 35 años de duración de la temperatura del aire, la humedad relativa y la precipitación en el sistema arrecifal del suroeste del Golfo de México. Los datos provinieron de un modelo climatológico, pero para evaluar su fluctuación local, las diferencias con los registros in situ se estimaron cuando los registros estuvieron disponibles. Las tres variables mostraron coherencia con el registro de alta presión del sistema de alta presión del Atlántico norte en tiempos similares y en periodos de 4 a 8 y > 10 años, lo que evidencia la influencia, a escala regional, de las señales de El Niño Oscilación del Sur (ENOS) y la Oscilación Multidecadal del Atlántico (AMO). Las anomalías positivas y negativas mostraron tendencias lineales que representan un aumento de eventos más cálidos y húmedos dentro de una climatología estacional en el área de estudio del Golfo de México, y presentaron una correlación relativamente alta (> 0.5) con el modo AMO. Los periodos de retorno de valores extremos variaron de 5 a 10 años. En general, las tendencias y los eventos extremos mostraron patrones similares a escala regional, pero el aumento de la lluvia puede ser mayor en la ubicación central del área de estudio. Una mayor frecuencia de eventos extremos podría amenazar los ecosistemas locales y a la población. Son necesarios planes y acciones de gobierno a escala local para lograr una adaptación preventiva al clima.ABSTRACT Local and regional climate trends drive rates of change in coastal ecosystems. To better understand local climate, 35-year-long time series of air temperature, relative humidity and rainfall were analyzed along the reef corridor of the southwestern Gulf of Mexico. Data came from a climatological model and to assess its local performance, differences with in situ records were estimated when available. All three variables showed coherence with the record of the North Atlantic high-pressure system (also known as the Bermuda High) at similar times and periods between 4 to 8 and >10 years, evidencing the influence, at this regional scale, of El Niño Southern Oscillation (ENSO) and the Atlantic Multidecadal Oscillation (AMO). Positive and negative anomalies showed linear trends depicting an increase of warmer and moister events during a seasonal climatology at the reef corridor of the southwestern Gulf of Mexico and a relatively higher correlation (> 0.5) with the AMO mode. Return periods of extreme values varied between 5 and 10 years. In general, trends and extreme events showed similar patterns at a regional scale, but the increase in rainfall is expected to be larger near the central location of the study area. A higher frequency of extreme events could threaten local ecosystems and human populations; therefore, plans and actions at local scales of governance are needed to achieve preemptive climate adaptation.
