Term 2 - Theme 2 (1) Flashcards
Human-Environment interactions
The environment as a resource e.g. agriculture. the environment as a sink e.g. sewage, industrial wastes. The environment as a hazard e.g. storms, pollutants etc.
‘Natural’ - Smith, 2013
Any natural process of phenomenon that may causes loss of life, injury or other health impact, loss of livelihoods and services, social and economic disruption or environmental damage’.
‘Technological’ - Smith, 2013
Hazards orginiating from technological or industrial corridors, including accidents, dangerous procedures or infrastructure fails that may cause loss of life, injury, illness or health impacts, property damage….
‘Socio-natural’
e.g. floods linked to deforestation, agricultural practice.
‘Na-Tech’
e.g. Fukushima.
Hazard
‘a potential threat to humans and their welfare arising from a dangerous phenomenon or substance that may cause loss of life, injury, property damage and other losses or damage.
Risk
the combination of the probability of a hazardous event and its negative consequences.
Disaster
When large numbers of people are killed, injured or adversely affected, the event is termed a disaster. Can be described as a serious disruption to the functioning of a community or a society involving widespread humans, material, economic or environmental losses or impacts which exceed the ability of the affected community to cope. (UN/ISDR, 2009)
Pre 1950
Engineering - What are the causes for natural hazards and what protection can be provided. Scientific weather forecasting and large structures were built against natural hazards.
1950-70
Behavioural - Why do natural hazards cause death and economic damage and can changes in human behaviour minimize risk. Improved short-term and long term land planning so that humans can adapt.
1970-90
Development - Why do people in LDCs suffer so severely and what are the historical and socio-economic causes of this? Greater awareness of human vulnerability to disaster + an understanding of how low economic development contribute to disaster.
1990-
Complexity - How can disaster impacts be reduced in a sustainable way in the future. emphasis on the complicated interactions between natural and human systems, leading to improvement in the long-term management of hazards.
Are disasters ‘natural’?
Access to the environment as a resource and sink, exposed to environmental hazards. Social differences - class, gender, ability, age, social capital, political context, race/ethnicity etc.
Vulnerability
The characteristics of a person or a group and their situation that influence their capacity to anticipate, cope with, resist and recover from the impact of a natural hazard (Wissner et al 2003)).
Pressure Release (PAR) model - Root causes
Root causes - Political, social and economic factors which are spatially or temporarily distant, culturally and socially invisible.
