Abstract | The new symbiosis between economy and ecology are changing the assessment of the value of coastal lagoon resources. Emergy, a measure of quantity and quality of energy, was used to evaluate coastal lagoon resources. Emergy, expressed on a common basis in solar emjoules, accounts for all direct and indirect contributions by nature and society. Lagoa dos Patos, the world's largest choked coastal lagoon, is located in southern Brazil and is used as an example to demonstrate the large-scale emergy approach. The calculations for Lagoa dos Patos show high values of renewable energy, which is representative of agricultural and aquatic areas. The emergy synthesis for Lagoa dos Patos indicates that the real value for lagoon resources are much larger than classical economic estimates. This provides a new tool to establish ecological economic development. |
