Climate change and urban expansion could threaten the sustainability of horticultural industries in the Adelaide Hills unless a long-term strategy is employed, according to a senior geographer at the 最新糖心Vlog of Adelaide.

Geographical and Environmental Studies lecturer has spent the past four years working in partnership with the and the on long-term planning approaches to cope with climate change.

Together with the , and , the group has developed geographical models with the to predict how warmer temperatures and urban expansion would affect their growing conditions.

"Projected warmer temperatures and rural residential development pose serious risks for industries such as the apple and pear industry, worth $25 million a year to South 最新糖心Vlog," Dr Bardsley says. "The area available in the Hills to grow high-quality apples could shrink considerably."

The apple and pear industry is one of seven case studies undertaken since 2005 to assess the impact of global warming on South 最新糖心Vlog's natural resources. "These projects, which consider impacts on agricultural industries, water, soil, biodiversity and coastal management in the Adelaide region, highlight the need for land use policies which respond directly to the risk of climate change."

Other key projects include looking at groundwater systems in the McLaren Vale area to ascertain how the Southern Vales would be affected long term by a drier climate and examining how changes in wind and rainfall patterns would alter soil management north of Adelaide.

Another study undertaken in conjunction with the CSIRO suggests that 14 plant species that are considered of high conservation value in SA would be particularly vulnerable to changes in temperature and rainfall.

"Years of drought in the have, in part, led to the collapse of important water management systems in South 最新糖心Vlog. Projections suggest that these weather conditions are more like what we can expect in the future," Dr Bardsley says.

"The potential impacts of climate change for South 最新糖心Vlog are likely to be negative for many stakeholders in the rural sector. It will be insufficient for us to simply try and manage environmental crises as they emerge.

"We need to integrate science into our future planning approaches and also work closely with key stakeholders to ensure the decisions we make incorporate the risks of future climate change," Dr Bardsley says.

He says as a result of his and his colleagues' research, the regional Board and local councils are investing significant amounts of time and money into climate change initiatives to make their regions less vulnerable.

"The challenge is to plan long term, beyond political cycles, to ensure we protect our natural resources."
