Challenges to Expert Knowledge in Understanding and Managing Risk

51250 Diseases from poisonous substances in the environment are commonplace due to pollution and climate change is also a threat to human existence. People can be harmed in their daily activities and in different ways hence making the management of risks very complex. Expert knowledge in understanding and managing risk is therefore required and essential in the prevention of risk especially in known circumstances and also to reduce the negative consequences associated with risk. However, even expert knowledge can be contested in various ways thus adding to the uncertainty of risk. Risk is defined by Carter and Jordan (2009: 59) as “the state in which there is the possibility of known danger or harm which if avoided may lead to benefits and particular and known outcome combined with consequences of the outcome.” It is an inherent danger in anything. It is also a probability or a situation of uncertainty that something might happen. Carter and Jordan regard risk as to the central element of life in a risk society. For Tim Jordan, the risk is “a combination of known and unknown outcomes and consideration of which allows for managed uncertainty” (A Risky World? 2009, track 3). Hinchliffe on the other hand, views risk as to the balance between benefits and costs. This is especially so for economists who must consider costs and benefits of any project or activity before engaging in it so as not to suffer loss. In our daily activities, we encounter various risks hence we can say that risk is unavoidable though manageable if we are aware of it. Ulrich Beck in his social theory argues that we all live in a risk society (Beck 1992, cited in Carter &amp. Jordan 2009: 81). Risk comes from various sources. In the past, the risk was apparent in industries but due to rapid technological and scientific advancements and transformation to knowledge economy as well as globalization, risk in contemporary society is inherent everywhere.&nbsp.
