2 Latest estimates for global fossil fuel production

3 Number of seconds of work required to earn the money to buy a unit of electricity

4

5 The price of oil in euros

8 Biomass: Too valuable a resource just to burn

9 First, cut your miscanthus....

13 Hemp: a productive annual, but only 8-10 tonnes/hectare

14 The myriad uses to which hemp can be put

15 Ways of making the journey Crush or grind Ferment using yeast Break down using enzymes Digest using bacteria Hydrolyse Pyrolyse Catalyse Distil Reconstruct using algae

16 Utilising rape seed

17

18 Local activities enable better use of heat

19 One possible journey  1. Grind up the grass  2. Extract the protein  3. Put residue in digester to get methane along with sewage sludge and animal slurries, food waste etc  4. Treat the cellulose left, along with waste paper and wood waste, to turn it into platform chemicals using the Biofine process  5. Grow algae on the remaining liquor  6. Recover nutrients using char  7. Return nutrients to the land

23 More local processing to increase farm incomes and allow more nutrients to be returned

24 A variant on the process using pyrolysis rather than hydrolysis

25 How a terra preta soil compares with a normal one

26 How adding charcoal to the soil encourages fungal growth

27 Big increase in soil bacteria when charcoal added

28 Eprida char and no char

29 With and without char

30 The drivers forcing changes in land use * The prices of agricultural products will reflect their energy content. * People will have to work much longer to earn enough to pay for their food. * The higher prices relative to labour will allow more people to work the land or in agri-industries * Crops will be grown to maximise energy gain. Energy Return on Energy Invested. (EROEI)

31 Land use patterns we can expect by 2030 – 1 * Perennials will have scored over annuals. Low-till and no-till will have displaced most traditional tillage. * A lot of pasture land will have been converted to energy- plus crops because of the energy cost of producing meat. Plant protein will be eaten directly or via better converters like chickens

32 Why we are getting climate change

33

34 Land use patterns we can expect by 2030 – 2 * Farmers will receive tradable carbon permits for any increases in the amount of carbon they have sequestered in their land. * Equally, if they fail to maintain the carbon content, they will have to buy emissions permits at the current rate.

35 Seminar this week  Danny Day, the developer of the Eprida process, will be  giving a seminar on it at the Teagasc Ashton Food  Research Centre, this Friday, at 2pm.
