The document discusses Australia's future landscapes in the context of climate change adding complexity and stressors. It notes that landscapes are highly evolved systems that have co-evolved with culture over long periods of negotiations between people and nature. People shape landscapes and cultures may also be shaped by landscapes. The challenges of climate change, water and natural resource management are profound but there are also signs of hope if we invest in innovation, cultural diversity and new stories that celebrate nature.

3. Climate change adds complexity and compounds stressors, new and old challenges Past and future landscapes – all shaped by “complex negotiations” between culture and nature
4. Landscapes are highly evolved, co-evolved complex systems based on long term and complex “negotiations” between culture and nature
5. As complex systems, cultures and landscapes co evolve. People shape landscapes. Do landscapes shape cultures? People are constantly making the landscapes of the future
6. Do landscapes shape cultures? If so how? What influences and drivers ? People are making the landscapes of the future, In their own image of the ideal
9. Climate change: new challenges for landscape management, adding to old challenges. We need integrated planning and assessments Complexity of climate and ecological systems Invest in scientific capacity - dynamic non steady state systems Critical questions re thresholds and tipping points
10. Difficulty in predicting tipping points in natural systems – eg Aral Sea But if the scientific approach fails just try “force majeure” as an excuse. Or try finding incontrovertible evidence of the weather gods – I did!
14. 3. A scenario of transformational change built on policy, research and practice change: systemic innovation A story from the future, inspiration built on extrapolating small successes
15. Vast savannas managed with ancient and innovative firing techniques – production, conservation, services, sequestration, culture
16. New perspective on old problems – ecological management and restoration at a bioregional scale. Competitive advantage, seizing critical opportunities, building on two decades of reform; new industries and professions
17. Innovative design of structures and settlements to suit the climate – the best of applied evolutionary biology or bio-mimicry
18. Innovation in technology, system of governance Capitalism will find ways of adapting? New wealth from old landscapes? Services, sequestration, production, conservation, energy, biomass
19. 4. Critical climate impacts Global challenges ahead - The approaching storm? Climate chaos!!!
20. Climate is hotter and drier Global average temperature Australian average temperature Satellite estimate of soil moisture
21.
22. New uncertainty- end of stationarity. What if the recent drought is different? What if the factors that make Australia’s climate variable are vulnerable to global warning? What next? New states or frequency
23.
24. Assessment of current settings NRM policies reflect a deep desire to care for country – degradation is unacceptable The nations values and relationships with nature are changing. “ Australia no longer seen as cornucopia of resources for exploitation but in need of care” But now “quarry Australia”
25. Responsibility for 60 million years of separate evolution International obligations to protect unique biodiversity
26.
27. A contested history – new world nature replaced by agriculture – a vision of production: “ The soil in these grassy flats was of the richest description: indeed the whole of the country seemed capable of being converted into good wheat land, … and of being easily irrigated, at any time by the river. .... the genial southern breeze played over the reedy flats, which one day might be converted into clover-fields”. Major T.L. Mitchell , 1836
28. "Charles Darwin …. Visited Sydney in 1836. After an uncomfortable tramp over the Blue Mountains in a heat wave, he concluded that Australia could never become another America - its soil was too poor, its rains too unpredictable . Instead it must depend on becoming "the centre of commerce for the southern hemisphere and perhaps on her future manufactories.” McCalman, The Age, 10 August 2002.
30. From unimproved land to nature refuge From incentives to clear to incentives to care Redefining the values of native vegetation – including woodlands, arid and savanna systems Landuse and water policy in transition
31.
32. Large dams era 1920-1980’s – nation building and response to climate variability? 1990’s new policy directions for land and water “ dreams of taming the rivers, greening the desert, and making land productive, run deep in the national psyche”
34. Australia - an ancient nutrient poor land with low population, limited industrial development and poor water quality and ecological condition in most rivers
35. Australian ecosystems evolved to capture water and nutrients. When disturbed through clearing for agriculture they leak salt, soils, nutrients
36. Modified catchments, nutrient and suspended sediment loads and habitat Very high nutrient and suspended sediment loads Largely unmodified River and catchment Condition
37. Cost and consequences of transforming an ancient continent 4M tonnes of sediment pa and phosphorus exports - about 13,000 tonnes pa Most agricultural lands have erosion 5-50 times greater than pre-European settlement.
38. A landscape crisis – with many symptoms – eg lower lakes, Murray mouth, species loss, land degradation etc - continues, resounding call for farming revolution and new approaches to NRM Climate turns old NRM challenges into new bigger challenges
39. Building on the lessons and policy experiments What did we learn? Innovation systems can be applied to larger challenges of the 21 century – not just NRM … towards a transformative energy, food and carbon and conservation economy
40. The challenges remain profound – water, energy, carbon, food - decoupling, efficiency, a solar economy, the pressures of billions and the need for new scalable solutions
41. There is value of thinking about Australia’s diverse and rich landscapes in new and different ways – a conservation and cultural economy – and thinking about our skills as valuable – stressed tested by drought, variability, distance. Built from multi-culturalism, multi functionality New approaches to old problems Redefining landscape goals through NRM plans – redefining progress Measuring the right indicators of success Dreaming the country
43. “ Perceiving and valuing” Australia’s landscapes – beyond the poverty of a colonial, economic perspective of “resources” for exploitation or sustainable production but also including the wondrous, the celebration of nature, the cultural connections to place
44.
45. The future is unknowable but approachable The future of rural Australia – driven by demographics, global trends, peri-urban – demographics, structural change and NRM
46. Landscape management involves culture, practice and governance. We need innovation system and governance systems that work. New strategic R&D interventions – from problem solving to shared learning and system solutions
50. Learn to live as Australia’s Water is a limited resource! Bush burns! Floodplains flood! Droughts dry out the country – 70 out of 200 years Conclusions 2: Water and drought
51. Creativity, innovation, cultural diversity, innovation Celebrate successes and build new stories of hope Creation stories not extinction stories “ There is magic in boldness” Goethe
52. “… the way people think of themselves …will affect the way they behave in the physical framework of their lives”. … “ideas are all Australia has … Not military might, or a large population, or unique resources. … Ideas are what must sustain our democracy, nurture our community and drive our economy into new areas ( Paul Keating (2002)
53. Australia’s diverse bioregional landscapes will evolve in the next two hundred years in directions set by profound shifts in the underpinning cultural, institutional and economic relationships with nature, along with climate change and a reduced abundance of resources such as fossil fuels and fresh water
54. The value shifts of the early 21 century may become recognised as the end of the frontier and the beginning of the settler society. A new dominant culture emerges based on respect and care for nature in this ancient continent. New symbols and stories of hope, of restoration are emerging. These signs of hope inspire bolder action and bigger visions: eventually the momentum will be unstoppable. (Alexandra and Riddington, Futures Vol 39, 2006)

Rainfall has been very low Lowest on record rainfall in the key high yielding upper Murray catchment We have never had two consecutive very dry years

2007/08 water market trends Both 2006/07 and 2007/08 water seasons have proven that the theory of markets works when applied to water As water has become scarce during drought, water has moved from low value agriculture to higher value agriculture Water market has assisted irrigators with permanent plantings to manage their businesses through the drought
