Adapting Agriculture To Climate Change
"Given that our climate has already changed and that further change
seems inevitable, it is important to take a pro-active stance to
assess adaptation options, their benefits and costs, and how to alter
policy and investment environments to facilitate their uptake," says
lead author Dr Mark Howden of CSIRO.
Climate adaptation analyses can reward early adopters of climate
information, build the capacity for effective climate risk management,
inform infrastructure investment decisions and help inform
international discussions on reducing greenhouse gas emissions such as
those happening in Bali this week.
"Practical adaptations such as changing timing of plantings or the
varieties or species of crops grown might avoid the damage caused by 1
to 2 degree changes in temperature - those expected over the next few
decades," he says.
"However, their effectiveness declines with higher temperature
increases. Consequently, the damages from climate change will increase
unless a whole new array of adaptations are developed and used. These
adaptations may need to include diversification of production systems
and livelihoodsand would need supporting policies and programs in
addition to soundly based research and development."
