Risk management cycle

As the global trend towards industrialization accelerates, population boom and cities continue to grow ever larger, the environmental decision making- process is becoming increasing challenge. The risk management cycle is one of the most significant parts of the environmental decision- making process. The risk means that there is a potential threat out of the control…

A framework for environmental risk assessment

Environmental risk deals with the probability of an event causing a potentially undesirable effect (Beer and Ziolkowski, 1996). Probability is the mathematical measure of risk and risk assessment determines the nature of the undesirable effect. Over the past two decades, risk management has attained maturity and become a tool for informed decision making. The framework…

The future trends of Adaptive management

With the increasing human influence on nature, human are facing a series of challenges such as sea level rise, biodiversity loss, declining food production and water scarcity. Adaptive management as a new approach is not a panacea for all problems, it is only appropriate in a subset of natural resource management problems where both uncertainty…

Week 9 Complex Systems and adaptive management

Carl Walters and CS Holling, and originally termed Adaptive Environmental Assessment and Management (AEAM), this approach emphasizes identifying critical uncertainties regarding natural resource dynamics and the design of diagnostic management experiments to reduce these uncertainties (Walters 2007). The AM process is a learning cycle that can be distilled down to six stages (Fig. 1). Aside…

Politicising Science?!

Politics and science tend to be thought of as opposing terms. While in natural science there is no doubt the acceleration due to gravity is approximately 9.81 or that two hydrogen and one oxygen atom make a water molecule, in politics what is a fact may depend on who you ask. But science has not…

Week 8: Decisions: science, risk and knowledge

The environment risk management approaches for environmental decision making at four different levels. It is part of a long term project aimed at developing decision-making processes consistent with sustainable management.   Basic criteria for “good” decision making are efficiency, effectiveness and equity. A further criterion specific to environmental decision making is flexibility. In the context…

Week 7: Decision making methodologies

“Decision making is the study of identifying and choosing alternatives based on the values and preferences of the decision maker. Making a decision implies that there are alternative choices to be considered, and in such a case we want not only to identify as many of these alternatives as possible but to choose the one…

unit 10

This week adaptive management approaches is the most interesting one. For a long time, policies in my country can be defined as one-off policies. This means initiative changes would not occur during implementation of policies. Only complaint or abandonment can lead to changes. However, the concept of adaptive management catalyze innovations in policy-making. In the adaptive management circle, feedback, also known…

Integrating traditional knowledge to Adaptive Management

Increasing awareness of the long-reaching and intricate impacts of environmental issues has resulted in a dynamic challenge for environmental decision making systems.  Adaptive Management has emerged as an avenue for natural resource management that accepts there are gaps in the knowledge of these systems, but enacts a constant feedback mechanism. Illustrated in figure 1, this learning and…

Multi-criteria analysis in environmental decision-making

Decision-making in environmental projects needs to consider the connections between social, political, environmental and economic impacts. Various stakeholder views also affect the outcomes of decision-making. Multi-criteria decision analysis (MCDA) as a formal methodology of decision-making utilizes existing technical information and stakeholder values to support decisions in many fields and can be especially valuable in environmental…

Quantitative vs Qualitative Decision Making

When is it better to do quantitative or qualitative research? The answer to such question depends on what we want to achieve of course. A quantitative analysis can provide numbers, comparative and generalisable data. On the other hand, a quantitative analysis can provide deep understanding of contexts, perspectives and motivations. For us it is important…
