By Nicholas Lawrence A Closer Look at Ecological Thinking
Introduction • Big facet of sustainability is sustainable resource use • This can’t be done without understanding environmental dynamics/ using ecological thinking • Having ecological knowledge of the environment leads to a better understanding of the environmental dynamics and how to best work within the system.
The Study • Original Article: • Olsson, Per, and Folke Carl. “Local Ecological Knowledge and Institutional Dynamics for Ecosystem Management: A Study of Lake Racken Watershed, Sweden.” Ecosystems 4 (2001): 85–104. Print. • Crayfish management in Lake Racken, Sweden • They set out to show the existence of LEK (local ecological knowledge) and it’s importance in ecosystem management
Background • Crayfish are largely enjoyed in Sweden • The catching and eating of crayfish has a large cultural aspect • Crayfish plagued reduced native populations by 95% • Acid rain also threatens crayfish populations
Methods • Both qualitative and quantitative methods were used • 73 questionnaires sent to households with fishing rights • In depth qualitative interviews with 10 key informants • Participant observation through public meetings, informal meetings and newspapers
Ecological Principles • Time: long scale and short scale • Place: local climate and geographic traits • Species: local species and their interactions • Disturbance: type of disturbance, severity and duration • Landscape: local landscapes influence local populations and communities
Significance • Local ecological knowledge exists and is combined with scientific knowledge • Ecosystem was monitored at different levels • Comanagement played a key role in enabling the inhabitants to react to disturbances
Conclusion • Local ecological knowledge (LEK) was found at different scales within the community • LEK alone doesn’t imply sustainable management, the nature of that LEK is important and institutional arrangements have to exist to make it work • Lake Racken could benefit from • “adaptive comanagement systems—that is, flexible community-based systems of resource management tailored to specific situations and supported by and working in collaboration with concerned governmental agencies, educational institutions, and where appropriate nongovernmental organizations.”
