Sudden ecosystem shifts

Results highlights

Like other ecosystems, under certain pressures dryland ecosystems can suddenly shift to a new state characterised by a different structure, species composition and/or functioning. Once an ecosystem has shifted, it is not likely to return to its previous state.

Structural and functional changes in ecosystems affect the services that can be provided. This report details how those changes can be measured and gives results from the CASCADE study sites under pressures from grazing, fire and multiple, diffuse causes.

Natural and human induced drivers of change are analyzed in each of the CASCADE study sites. The impact of such changes on potential sudden ecosystem shifts are described in terms of a common unifying framework into which instability observed can be fitted. Climate is a governing driver for all Study Sites and land use, land cover, production, consumption and disposal drive the relationship between social and ecological systems.

In participatory workshops, stakeholders identified changes in environmental conditions that they have experienced over the last 20 years and discussed how they have adapted to them. They also described the kind of changes they expect to witness in the future and how they might to cope with them too.
