The scientific exchange had the following objectives: *Examine farming systems relevant to tropical Australia, e.g. peanut / cotton on light soils, drip / overhead head irrigation, conservation tillage systems. *Meet with researchers engaged in crop adaptation and climatic risk assessment work similar to my own professional expertise and relevant to tropical Australia. *Meet researchers with expertise with growing cotton in hot arid climates. * If possible visit one Native American / cotton farming partnership in Arizona with respect to its relevance to similar potential partnerships between cotton growers and indigenous Australians
