InnovationNetwork
• Develops and implements groundbreaking innovations for agriculture and rural areas
• Funded by Ministry of Agriculture• Budget € 4.5 million per year• Evaluation every 5 years
10
Making a flooding area for the river
Overdiepse Polder:730 ha flooding area, 0,3 m lower water level in river
14
Climate change and ecosystem
• Longer growing season• Mismatches in breeding and flowering• More exotic plants and animals
16
Goals of Dutch government
• 30% reduction of greenhouse gas emissions in 2020 compared to 1990
• Increase in sustainable energy from 2% in 2008 to 20% in 2020
• Doubling of energy saving from 1% to 2% per year
• 25-30 % less emissions of CH4 and N20
18
Main sources of greenhouse gases in agriculture
• CO2: energy use (greenhouses)• N2O: fertilizer, manure storage• CH4: dairy cows, manure storage
19
Energy from biogas
Drinking water
Waste treatment
Cooling and heating
Greenhouse as energy source
35 C25 C
24
Clustering of different agricultural sectors with non-agricultural sectorsand re-/upcycling of waste streams
Industrial ecology
Agropark
28
Biochar
Charcoal created by pyrolysis of biomass
• Energy from biomass• CO2 sequestration in the soil• Positive agronomic and environmental effects
30
Biology of algae
• 6CO2+12H2O C6H12O6+6O2+6H2O• Light• Primairy nutrients (N, P, K)• Heat• Salt and sweet water
36
Climate change: Policy instruments in The Netherlands
• Economic instruments (subsidies, tax profits, levies)
• Legislation / agreements• Knowledge development • CO2 emission trade
37
Conclusions
• Impact of climate change on Dutch agriculture is significant
• Ambitious goals to reduce greenhouse gases
• Technical solutions are promising• Policy instruments not yet in place
