L5 : Engaging at National Level with Governments Flashcards
What does mainstreaming DRR involve? (three things)
1) Governments prioritising DRR in their national policies
2) Incorporating DRR into plans and programmes for development in all sectors or fields
3) Increasing prior investment in DRR
What are the 6 elements of IEM (UK Integrated Emergency Management)?
1) Anticipation
2) Assessment
3) Prevention
4) Preparation
5) Response
6) Recovery Management
What are Category 1 (core) responders?
Responders are organisations involved in most emergencies at the local level.
What are the civil protection duties of Category 1 responders?
- Risk assessment
- Business continuity management (BCM)
- Emergency planning
- Maintaining public awareness and arrangements to warn/inform/advise public
- Share info and co-operate with other responders
- (local authorities only) provision fo advice to commercial and voluntary sectors.
What are Category 2 (co-operating) responders?
Likely to be heavily involved in some emergencies in their own sectors and are required to coordinate and share information with Category 1.
Category 1 & 2 responders form LRFs, what are LRFs? And what 2 organisations do they have a role under?
Local Resilience Forums
- National Resilience Capabilities Programme (NRCP)
- Emergency Response and Recovery
What do LRFs do?
Compile community Risk Registers and support Category 1 and 2 responders in their duties under the IEM framework.
What are the 6 main sources of evidence that can support Policy-makers and Implementing agencies?
1) National Risk Assessment (classified) and associated National Risk Register (public)
2) NHP (The Natural Hazards Partnership), provide info/research/analysis on natural hazards and risk impacts
3) SAGE (Scientific Advice Group for Emergencies), can be convened in national emergency to inform Cabinet Office Briefing Room committee (COBR)
4) Commissioned reports e.g. Foresight Projects and The Pitt Review
5) Flood Risk Regulations (2009) to implement the EU Floods Directive within UK law
6) Events generating public debate on flood management
What is the NRR?
How often is it developed?
- National Risk Register of Civil Emergencies
- Developed every 2 years to cover events that could plausibly happen in the next 5 years.
What is the NHP and why was it set up?
What does it comprise of?
What does it produce?
- Natural Hazard’s Partnership
- Pitt review 2007 found that hazard info and warning were too disjointed and science not easily transferred into practice
- establish a forum for the exchange of natural hazards knowledge, ideas, expertise, intelligence and best practice; provide timely and consistent advice to government and emergency responders for civil emergencies and disaster response; develop new services to assist in disaster response preparedness
- 26 gov departments and agencies across the UK (supported by Cabinet Office)
- Produces a DHA (Daily Hazard Assessment) - overview of next 5 days available to Cat 1 & 2 responders, science and hazard notes, NRA and NRRs and HIMs, development of Hazard Impact Models (HIMs).
What does HIM stand for, and what are they designed to do?
What are their inputs?
What are they different from?
What ensures consistency between HIMs?
Designed to be run quickly by end-users to support operational decisions before and during events - driven by meteorological inputs, incorp UK pop and infrastructure data to give impacts and risk (not financial losses).
Different from ‘black-box’ CAT models used for risk financing at global scales - these are computationally intensive, requiring catalogues of probabilistic hazard simulations, detailed vulnerability informations, and calculations of financial losses.
Hazard Impact Framework (HIF) - ensure consistency and alignment between HIMs
Define River (fluvial) Flooding
When a watercourse cannot cope with the water draining into it from the surrounding land
Define Coastal Flooding
From a combination of high tides and stormy conditions and sometimes from atmospheric low pressure systems
Define Surface Water (pluvial) Flooding
Define Surface Water (pluvial) Flooding
Intense rainfall exceeds local drainage capacity (more difficult to predict timing and extent than fluvial floods)
Define Sewer Flooding
Sewers are overwhelmed due to heavy rainfall or blockages
Define Groundwater Flooding
groundwater levels rise above the ground surface (typically in areas with
extensive chalk or sandstone aquifers, or local sand or river gravels in valleys underlain by less
permeable rocks)
What does the EA produce?
flood maps for planning zonation and for National Flood Risk
Assessment, NaFRA
What is used to predict surface water flooding?
Probabilistic rainfall forecasts (Met Office), converted into surface water runoff using the CEH
(Centre of Ecology & Hydrology) grid-to-grid model (G2G) to give a SWF footprint (1km2)
• Environment Agency flood model impacts library then used to determine potential impact
• Under development: dynamic connection of G2G with Env Agency flood modelling approach
Definition of impact used in HIMs
Impact defines the total effects of a single event: surface water flooding, high winds or landslides
Definition of risk used in HIMs
Risk incorporates uncertainty via probabilistic distributions of hazard severities, exposure levels
and vulnerability characteristics (i.e. potential impact of an event with its likelihood)
What is WWNP and how does the EA define it?
Why do we need to employ WWNP
Working with Natural Processes (WWNP)
‘Taking action to manage fluvial and coastal flood and coastal erosion risk by protecting, restoring
and emulating the natural regulating function of catchments, rivers, floodplains and coasts’
The Pitt Review noted that flood and coastal risks could not be managed simply by building larger
hard-engineered defences – softer, more sustainable approaches were needed. EA should work
with others to identify rural and urban solutions.
3 main WWNP techniques
Flood storage : ‘The act of deliberately retaining or storing water on a floodplain during a flood event and subsequently its slow release back into a watercourse in order to reduce the risk of flooding’. Sustainable Drainage Systems (SuDS) : ‘Management practices and control structures (commonly in urban areas) designed to control surface water run-off as close to its origin as possible, before it enters a watercourse’. Managed realignment : ‘The deliberate flooding of an area that was not previously exposed to flooding by breaching or removing flood defences, to achieve flood and coastal risk management benefits as well as other benefits (e.g. habitat creation)’.
