4. Life on Earth is
deteriorating fast
worldwide.
Virtually all indicators
of the global state of
nature are decreasing:
biomes, ecosystems, species, varieties
and breeds
5. Nature is being degraded at a rate and scale
unprecedented in human history
75% of the land surface is significantly altered by human
actions
>85% of wetlands have been lost
Only 13% of oceans can still be viewed as wilderness
9. Some possible actions are politically palatable
Produce and consume food sustainably
• Reduce food waste
• Promote sustainable and healthy diets
• Promote biodiversity friendly management practices (e.g. agroecology)
Build sustainable cities
• Limit urban sprawl
• Promote low impact public transportation, nature sensitive road networks
• Expand vegetation cover, promote urban gardens
• Manage for ecological connectivity
• Promote sustainable water and solid waste management
Some general principles are discursively accepted
Promote interconnections between sectoral policies (e.g. agriculture,
fisheries, tourism, energy, etc.) – policy mainstreaming
Enable participation of a large diversity of actors (e.g. local communities)
10. Food production and conservation goals:
complementary and interdependent.
Sustainable fisheries: integrated management
on land, in freshwater and oceans
Land-based climate change mitigation:
attention to trade-offs
Nature-based solutions in cities:
crucial for global sustainability
The 4 most urgent challenges to be addressed
Food (Agr&Fisheries), CC mitigation & Urbanization
11. Need for rapid implementation of existing
instruments and bold decisions for transformative
change.
Knowledge and tools available
…
But generally implementation is
lacking
too slow or timid
12. the elephant in the room
1. Urgency clashes with vested interests to
protect the dominant economic development
paradigm based on material and energy
intensive growth-mania
2. Insufficient attention to the developmental
role of abiotic resources
20. A key constituent of sustainable pathways
is the evolution of global financial and
economic systems to build a global
sustainable economy.
One that steers away from the current
limited paradigm of economic growth and
reliance on abiotic resources.
21. We must put in montion transformative change that address
the root causes of the socio-ecological crisis
Total consumption and waste
Externalities and telecouplings
Technology, innovation & investment
Visions of a good life
Values and action
Inequalities
Justice and inclusion in conservation
Education and knowledge generation and sharing
22. Confronting the challenge of meeting current and future
developmental and environmental goals requires
new collective visions of
living well in/with (vs. from) nature
