Surely you have ever heard that there are people more vulnerable to a virus or another type of disease, that is, that they are those who have the least capacity to resist the virus, or the pathogen in question, when infected, so who are weaker or more vulnerable to it.
Vulnerability can be applied in different fields: education, culture, economy, society, the environment, among others. This Green Ecologist article will talk about what is environmental vulnerability, giving its definition and some examples of it. In addition, the difference between risk and environmental vulnerability will be explained.
Environmental vulnerability refers to the degree of resistance of a system, subsystem or component of a system in the face of the two major environmental problems that are occurring throughout the planet: global warming and the loss of biodiversity. Both caused directly or indirectly by anthropic activities. Although also with environmental vulnerability refers to the degree of resistance of the environment to natural phenomena, such as an earthquake.
Environmental vulnerability depends on two factors:
Nature is very wide and that is why not all areas present the same degree of vulnerability. Those most vulnerable have less capacity to respond to changes, in addition to being more exposed, thus increasing the amount of damage and a longer recovery time. However, those less vulnerable areas have a greater capacity to respond and are less exposed, thus receiving less damage and having a recovery in the shortest time.
Next, we will present several examples of very vulnerable and not very vulnerable ecosystems or species.
These are some examples of environmental vulnerability, focusing on ecosystems or species with a high environmental vulnerability, that is, they are in danger of extinction or in the category of Endangered:
Ecosystems or species with a low environmental vulnerability, in the category of Least ConcernIn other words, until now they are not being affected by environmental problems or, they are adapting to environmental changes.
The concept of risk, in the environmental context, refers to the probability that the environment suffers damage due to human action or some natural phenomenon. But to better understand the concept of risk, we also have to understand that of threat (or danger) and vulnerability, although we now know this.
A environmental threat or danger It is defined as the probability of a catastrophic event occurring during a given time in the environment. On the other hand the environmental risk it is the result of the existence of a threat (or danger) and of the degree of vulnerability of nature. The threats would be environmental problems caused by human activities and natural phenomena, and vulnerability depends on exposure and adaptation capacity. Risk = Threat + Vulnerability
Therefore, the difference between risk and vulnerability is that risk determines whether the threat will affect more or less a system or component of it depending on its vulnerability. And vulnerability measures the degree of loss and damage that nature has received from a threat.
