ALiSEA Sustainability Assessment is derived from an existing sustainability assessment tool called IDEA. The IDEA method (Indicateurs de Durabilité des Exploitations Agricoles or Indicators of Sustainable Farm Development) was created upon request of the General Board for Education and Research of the French Ministry of Agriculture which, since 1996, aims at assessing and diagnosing the sustainability of agricultural systems.The purpose of ALiSEA SA is to assess farms led by young farmers in the Mekong Region on a common framework based on the three dimensions of sustainability. Using a harmonized approach contributes to making sustainable farms more measurable, verifiable and visible.
