Mekong: the Challenges of Scale
2. A set of interacting or interdependent
component parts forming an intricate whole.
Every system is delineated by its spatial and
temporal boundaries, surrounded and
influenced by its environment, described by its
structure and purpose, and expressing in its
functioning.

If managed and
coordinated as a

to society would
increase by 3โ12%

9. โฆthere is often no serious assessment for developing a
holistic concept of the entire watershed including all
tributaries. This concept should go far beyond
hydropower development and create an innovative
management model, which considers water,
environment, livelihood, food security, etc.โ

10. Impact assessments
๏ง Never โwhole systemโ.
๏ง Restricted number of
variables.
๏ง Focus only on variables
for which there is some
or partial data.
๏ง Land use change, food
production, benefit
sharing and/or
ecosystem services very
rarely considered.
