SEMINAR: Climate change adaptation: water conservation and crop production in south-western Australia and the Loess Plateau of China
|Climate change adaptation: water conservation and crop production in south-western Australia and the Loess Plateau of China : this seminar is part of the Centre for Water Research seminar series.
Climate simulation models suggest that mean temperatures on the Loess Plateau of China will increase by 2.5 to 3.75°C by 2050, while those in the cropping region of south-west Australia will increase by 1.25 to 1.75°C. The rainfall in south-west Australia rainfall is predicted to decrease by 20 to 60 mm, rainfall on the Loess Plateau of China is not expected to change.
Farming systems in both regions differ markedly in scale, but both have adopted water conservation techniques that benefit crop yields. In south-west Australia zero tillage and adequate use of fertilizers have enabled farmers to increase their rainfall use efficiency and yields of cereals, canola and legumes, while on the Loess Plateau, mulching with plastic, gravel and residues, crop sequence, fertilizer/organic manure application and supplementary irrigation have improved precipitation use efficiency and yields of several crops and enabled the production of maize in areas of the Loess Plateau where temperatures limit its production.
The implications of climate change and adaptation strategies such as agronomic management and crop breeding in the two regions will be discussed in relation to future improvements in water productivity and food production.
