Question

data interpretation on ecosystem for sustainable living...


In 200 words...​

Answer 1

Healthy terrestrial ecosystems are vital for human welfare and survival, as they provide us with essential products and benefits. Over 90% of our food comes from terrestrial ecosystems, which also provide energy, building materials, clothes, medicines, fresh and clean water

Answer 2

Management applications of ecosystem analysis commonly encompass large areas, which imposes a requirement that the types and accuracy of data match the available sources. Ecosystem analysis can provide through model simulations some estimates of important variables that are difficult to measure directly. For example, using hydrologic equilibrium theory, one can infer a balance that is commonly established among climatic properties, soil water holding capacity, and the maximum leaf area that forests will support. It is a seeming contradiction that these rather sophisticated ecosystem models and analytic tools are particularly valuable in data-poor areas. A handful of key measurements, some acquired by satellite and synthesized with a model, can allow an inference of ecosystem activity that would be nearly impossible to acquire through standard ground surveys. The first requirement in preparing for regional scale assessments is to construct a coordinated, geographically specific information base that includes the most important system attributes such as weather data, satellite imagery of the mosaic of vegetation and soils, snowpack depth, streamflow, and location of wildlife populations. Most established land management agencies have acquired a tremendous amount of these kinds of data, but they are often not available in a consistent, geographically referenced format. The second requirement is to maintain the array of ecosystem and environmental data in an immediately accessible form.
