Modelling forest fire and firebreak scenarios in a mediterranean mountainous catchment: Impacts on sediment loads.

J Environ Manage 2021 Apr 3;289:112497. Epub 2021 Apr 3.

Water Research Institute, National Research Council, Francesco De Blasio 5, 70132, Bari, Italy.

Forests provide a number of ecological and hydrological services, for instance, contributing to decreased water and sediment yields through increased infiltration and reduced soil erosion. However, forest fires can turn positive forest services into drawbacks, enhancing surface runoff and soil erosion and damaging both hillslopes and downstream aquatic life in rivers. Therefore, appropriate mitigation strategies should be developed to limit these negative effects. Read More

An Attention-Based Multilayer GRU Model for Multistep-Ahead Short-Term Load Forecasting.

Sensors (Basel) 2021 Feb 26;21(5). Epub 2021 Feb 26.

School of Electrical Engineering, Korea University, 145 Anam-ro, Seongbuk-gu, Seoul 02841, Korea.

Recently, multistep-ahead prediction has attracted much attention in electric load forecasting because it can deal with sudden changes in power consumption caused by various events such as fire and heat wave for a day from the present time. On the other hand, recurrent neural networks (RNNs), including long short-term memory and gated recurrent unit (GRU) networks, can reflect the previous point well to predict the current point. Due to this property, they have been widely used for multistep-ahead prediction. Read More

Prediction of regional wildfire activity in the probabilistic Bayesian framework of Firelihood.

Ecol Appl 2021 Feb 26:e2316. Epub 2021 Feb 26.

Ecologie des Forêts Méditerranéennes (URFM), INRAe, 84914, Avignon, France.

• Modelling wildfire activity is crucial for informing science-based risk management and understanding the spatio-temporal dynamics of fire-prone ecosystems worldwide. Models help disentangle the relative influences of different factors, understand wildfire predictability and provide insights into specific events. Here, we develop Firelihood, a two-component Bayesian hierarchically structured probabilistic model of daily fire activity, which is modelled as the outcome of a marked point process: individual fires are the points (occurrence component), and fire sizes are the marks (size component).

A Multi-Analysis Approach for Estimating Regional Health Impacts from the 2017 Northern California Wildfires.

J Air Waste Manag Assoc 2021 Feb 25. Epub 2021 Feb 25.

University of Washington.

Smoke impacts from large wildfires are mounting, and the projection is for more such events in the future as the one experienced October 2017 in Northern California, and subsequently in 2018 and 2020. Further, the evidence is growing about the health impacts from these events which are also difficult to simulate. Therefore, we simulated air quality conditions using a suite of remotely-sensed data, surface observational data, chemical transport modeling with WRF-CMAQ, one data fusion, and three machine learning methods to arrive at datasets useful to air quality and health impact analyses.

Alissa Cordner

Qual Sociol 2021 Feb 16:1-23. Epub 2021 Feb 16.

Whitman College, 345 Boyer Ave, Walla Walla, WA 99362 USA.

As climate change increases the frequency and severity of disasters, and population and social changes raise the public's vulnerability to disaster events, societies face additional risk of multiple disaster events or other hazards occurring simultaneously. Such hazards involve significant uncertainty, which must be translated into concrete plans able to be implemented by disaster workers. Little research has explored how disaster managers incorporate different forms of knowledge and uncertainty into preparations for simultaneous hazards or disaster events, or how front-line disaster workers respond to and implement these plans.
