Why Communities Settle near Rivers?
5 Good Reasons:
• Tens of thousands lineal km of causeways and
Canals (Erickson, 2000)
• 20000 Occupation mounds (between 0.5 and 13
hectares or more) (Lijerón, 1997)
• 1M hectares of raised cultivation fields,
platforms and mounds (Lee, 1995)
• 350.000 hectares of geometrically oriented
ponds (Barba, 2003)

Impacts of diversification on income
• Growing average incomes (reduced losses)
• Reduced income variance (and risk)
• Incorrelated or inverseley correlated incomesCurrent Situation Territorial Adaptive Management

Conclusion
• Urban people have a lot of things to learn from rural people, more inagriculture.• Don’t loose the chance to recover ancestral knowledge.• There is always an important alliance between local governments and non gubernamental initiatives.• Climate changes affect more the most vulnerable, urban agriculture is also incomes for the poorest.• Always try to promote appropriate technology South-South.• Fresh food for the people.• Make it simple and will be replicable.
