Sustainable Practice Targets - an overview
- 1. Sustainable Practice Targets - an overview Presented by: Dr Michele Barson, Science Adviser to Caring for our Country
- 2. Caring for our Country objectives … initiative that seeks to achieve an environment that is healthy, better protected, well managed, resilient, and provides essential ecosystem services in a changing climate. Essential ecosystem services include protected biodiversity, clean air and water and healthy soils which support sustainable food and fibre industries.
- 8. Why soils? Soils are the engine room for food production contain vast quantities of carbon and water and support the majority of terrestrial biodiversity supply key ecosystem services Provide: food, fibre, clean water, biodiversity Regulate: water storage, carbon sequestration, filter contaminants, absorb organic waste a part of the landscape closely managed by farmers
- 9. Key soil condition factors being addressed in Caring for our Country Soil carbon Soil pH Wind erosion Water erosion
- 11. essential ecosystem services (protected biodiversity, clean air and water and healthy soils) in a changing climate (C4oC’s objective) AND
- 15. follow up in 2009-10 and 2011-12
- 16. 33,000 farm businesses (EVAO > $5000 surveyed)
- 18. Preliminary ARMS results - Landscape scale conservation target
- 20. National methods for soil carbon and pH monitoring
- 21. Investigation of potential for improving detection and monitoring of water erosion
Notes de l'éditeur
- In summary, outcomes we are looking for from all industriesMaintenance of good ground cover to reduce the risk of soil loss through wind and water erosion and to help build soil carbonBetter management of the soil acidification process to avoid surface and subsurface acidification problemsThese practices are also being promoted through state agencies, industry bodies and community groupsContribute to on farm resilience and profitability as well as ecosystem services
- Caring for our Country commissioned the Australian Bureau of Statistics to develop the Agricultural Resource Management Survey (ARMS) to help report on rates of adoption of land management practices being encouraged through C4oC fundingSome data from the 2007-08 survey are currently on the webAnticipate having the data for 2009-10 at the NRM region, state and national levels in DecemberVery keen see any data on land management practices collected by industry, state agencies and other groups to see if trends are similarAim of this survey go broad, large sample to complement industry surveys which generally have smaller samples , more depth
- Some data back to 1995/96No cultivation – no of farmers using no cultivation apart from sowing is now 4x greater than in 1995-96 and a 55% increase in area under this practice since 95-96Crop residue retentionNo of farmers using this practice x3 since 1995-96 area increased by 47% since 1995-96Soil acidification management needs improvement
- Generally positive
- Most of our progress has been with monitoring wind erosion, bring together on ground obs. of erosion, dust monitoring, remote sensing and modellingMost progress here because the science and some of the technology in placeChange can occur quite quickly – poor ground cover plus wind leads to dust stormsCarbon and pH change – hard to detect over measurement periods of less than 5 years. Have funded CSIRO and state agencies to look at how a national monitoring system could be implemented, but will need significant investmentWatter erosion reviewed options more work needed here to develop methods
