Simulating mesoscale coastal evolution for decadal coastal management: A new framework integrating multiple, complementary modelling approaches

Publication ID: pub.1040461568

Keywords: Coastal Morphology; Hybrid Modelling Approach; Model Coupling; Morphodynamics; Shoreline Management; Suffolk Coast; UK

Coastal and shoreline management increasingly needs to consider morphological change occurring at decadal to centennial timescales, especially that related to climate change and sea-level rise. This requires the development of morphological models operating at a mesoscale, defined by time and length scales of the order 101 to 102years and 101 to 102km. So-called ‘reduced complexity’ […]

A robust stochastic Casualty Collection Points location problem

Publication ID: pub.1117159426

Keywords: Bhopal; Casualty Collection Points; Humanitarian Logistics; India; OR in Disaster Relief; Robust Optimization; Stochastic Programming

In this paper, a Casualty Collection Points (CCPs) location problem is formulated as a two-stage robust stochastic optimization model in an uncertain environment. In this modelling approach, the network design decisions are integrated with the multi-period response operational decisions where the number of casualties with different levels of injuries coming from the affected areas is […]

Conceptualising cultural ecosystem services: A novel framework for research and critical engagement

Publication ID: pub.1045220401

Keywords: Cultural Ecosystem Services; Ecosystem Assessment; Interdisciplinarity; Methods; Theory; UK

The construction of culture as a class of ecosystem service presents a significant test of the holistic ambitions of an ecosystems approach to decision making. In this paper we explore the theoretical challenges arising from efforts to understand ecosystems as objects of cultural concern and consider the operational complexities associated with understanding how, and with […]

Limited release of previously-frozen C and increased new peat formation after thaw in permafrost peatlands

Publication ID: pub.1099927607

Keywords: Canada; Greenhouse Gases; Northwest; Peatlands; Permafrost Thaw; Radiocarbon; Thermokarst; Wildfire

Permafrost stores globally significant amounts of carbon (C) which may start to decompose and be released to the atmosphere in form of carbon dioxide (CO2) and methane (CH4) as global warming promotes extensive thaw. This permafrost carbon feedback to climate is currently considered to be the most important carbon-cycle feedback missing from climate models. Predicting […]

Global review of shark and ray entanglement in anthropogenic marine debris

Publication ID: pub.1114064203

Keywords: Atlantic Ocean; Elasmobranch; Entanglement; Ghost Fishing; Global; Indian Ocean; Marine Debris; Pacific Ocean; Rays; Sharks

Agave: A promising feedstock for biofuels in the water-energy-food-environment (WEFE) nexus

Publication ID: pub.1125902643

Keywords: Agave; Australia; Biofuel; Environmental Impact; Kalamia Estate; Life Cycle Analysis (LCA); Queensland; Water-energy-food-environment (WEFE)

The aim of this study was to conduct the first comprehensive life cycle assessment and economic analysis on ethanol produced from agave. Compositional and field data from a field experiment in Queensland, Australia was used. Our study shows that ethanol yields from agave (7414 L/ha/year) are comparable to Brazilian sugarcane (9900/L/ha/year) and higher than US corn […]
