Problem definition

Forests are a fundamental element in the earth’s ecological balance, biodiversity, water resources, economy and air purity. Forests are confronted with numerous threats such as deforestation and wildfires. Due to climatic and environmental changes, incidences of wild forest fires have increased. Fires are a major threat to many forests in the USA that are vital for the survival and ecological balance and environmental sustainability. Large-scale forest fires not only destroy flora but also deprives the land of flora, spoils water sources, causes air pollution, and intensify desertification.

Forest fires have short-term and long-term effect on the forest ecosystem. It disrupts the food web and alters the ecosystem energy transfer.

The food web effect

Tropical food web assumes the typical structure of producer, primary consumers, secondary consumers, tertiary consumers and decomposers.  The forest vegetation provides food to primary consumers that include deer, elk, small mammals, fish and insect.  The secondary consumers include animals such as owls, weasels, raccoon, woodpecker, frogs and carnivorous such as cougar, bear, lynx and wolves.

The ways that engineered system impact that web

Prolonged forest fires alter the pH of water stream of the affected area.  Engineered systems can be used to reverse this change in water resource caused by wildfires. Such a system would maintain the balance of the food web by maintaining a population of salmon and insects. Deer and elk are the largest primary consumers. Their live is threatened by the fires that not only destroy their habitats but also destroys their food.  Their population may reduce drastically after the fire thus affecting the popular of cougar, bear, lynx and wolves (tertiary consumers).  Engineered system can be used to facilitate the recovery of forest.

 Ideas about how engineered systems could be improved to benefits an ecosystem

One important goal of engineering is the pursuit of efficiency. Technical efficiency helps to accomplish goals with less physical activity while economic efficiency reduces financial outlays, labor and cost.  Therefore, a well-designed system free up society’s scarce resources to meet other societal needs.

The engineered systems should be based on a thorough requirement analysis, should have clear functional and physical definition and design validation. Need analysis defines and identify the need for a new system or model, demonstrates the feasibility, and outlines system operational requirements. Concept exploration examines the feasibility concepts and defines functional performance requirement and concept definition explores alternative concepts, determine the preferred concept on the basis of performance.

Testing and evaluation of the model should be incorporated in every step of model development. Testing and evaluation will assist to ensure the system meet the objectives of the system.
