Why Conventional Agriculture Is Not Sustainable ?

ž  Soil Degradation
ž  Waste and Overuse of Water
ž  Pollution of the Environment
ž  Dependence on External Inputs
ž  Loss of Genetic Diversity
ž  Loss of Local Control over Agric.Production 

AGROECOSYSTEM VS. NATURAL ECOSYSTEM


ž  Natural ecosystem is closed, or at least, unmanaged 

  ecosystem

  Closed ecosystem—all elements recycled through 

   ecosystem—not often pure closed ecosystems 

    anymore—humans frequently involved.

ž  Agroecosystem is an open ecosystem, or managed 

  ecosystem:

  Producer moves plants, animals, environmental 

   factors (fertilizers, feed) in & out of ecosystem.

  Will not continue on its own without 

    management.

  If left alone, would progress toward closed 

   ecosystem, but probably not the same asoriginal 

   ecosystem before agriculture without human 

   input again.
