• In conclusion
• People are the most valuable component
• The interlocking of multiple agencies and
  actions to work towards a common outcome
• The use of a core environmental problem to
  unlock multiple developmental opportunities .
• Linking ecological integrity and social justice
  . . Working for Water /Wetlands / on Fire /
  Working for Woodlots
• Provide the tools for beneficiaries to maximise
  their returns
• Make a start lessons are learnt along the way
