Question

When Pi is productivity per unit input of the limited or non-renewable resource, Si is alteration in soil properties, Wi is change in water resource and quality, Ci modification in climatic factor and t is the time, the index of sustainability (Is) can be computed as:

• A. Is = (Pi \(\times\) Si \(\times\) Wi \(\times\) Ci) t
• B. Is = f(Pi \(\times\) Si \(\times\) Wi \(\times\) Ci) t)
• C. Is = f(Pi + Si + Wi + Ci) \(\times\) t
• D. Is = [f(Pi + Si + Wi + Ci)] t

Hint:

Sustainability index:
Is = [f(Pi + Si + Wi + Ci)] t.
Higher value indicates higher sustainability.

Answer 1

The Correct Option is D
