Global food crisis l.jpg
Global food crisis

  • Rapidly increasing population

  • Diversion of foods to fuels

  • Increased costs for water, fertilizer, fuel

  • Multiple demands for farmland (urban sprawl, industrial and mining, solar and wind generation, wildlife conservation, watershed protection, etc.)

  • Need for second generation biofuels


Need new model for food production l.jpg
Need new model for food production

  • Green Revolution – huge increase in food production, but heavy reliance on irrigation, fuel and fertilizer

  • Blue Revolution – almost 50% of seafood is farm raised, but many environmental impacts (effluents causing eutrophication, algae blooms, cage conflicts with other users in oceans, bays and lakes)


Green revolution l.jpg
Green Revolution

Benefits

Costs

Large demand for fertilizer

Increases in irrigation (area, amount, frequency)

Less “organic”

More pollution

Needs

More education & training

  • Large increases in yield

  • Improved varieties

    Needs

  • Increased demand for trained specialists

  • Sophisticated farmers


Blue revolution l.jpg
Blue Revolution

Benefits

Costs

Demand for feeds with fishmeal

Demands for clean water (volume and surface area)

Diseases and parasites

Effluent pollution, algae

Needs

On-land farms

More education & training

  • Large increases in seafood yield

  • Domesticated stocks

    Needs

  • Increased demand for trained specialists

  • Sophisticated farmers


Historical perspective l.jpg
Historical perspective

  • Traditional farming around the world integrated livestock and crops

  • East and South Asian farmers have long tradition of integrating agriculture and aquaculture

  • Asian sustainable farming systems support huge populations

  • Fish – vegetable – rice (complex carb) diet is suggested by most nutrition experts


Historical perspective7 l.jpg
Historical perspective

  • Modern agriculture cannot follow Asian model of small-farm integrated systems (gardening)

  • We need an industrial version merging aqua- and agri- cultures

  • Taking the best of the Green and Blue Revolutions


Green revolutions weaknesses are blue revolutions needs and vice versa l.jpg
Green Revolutions weaknesses are Blue Revolutions needs and vice-versa

  • Fertilizer demand

  • Increase in irrigation

  • Chemical fertilizers pollute groundwater

  • Industrial crops with by-products

  • Aquaculture effluent rich in N and P

  • Fish grow well in irrigation water

  • Fish wastes are slow release, organic

  • Fish feeds need alternatives for fish meal and oil


Models l.jpg
Models vice-versa

  • Arid lands

  • Tropical lands

  • Tropical coastal

  • Temperate lands

  • Marine


Arid integrated systems l.jpg
Arid Integrated Systems vice-versa

  • Tilapia Grapes, wheat, olives, barley, sorghum, cotton, melons, peppers


Data report tilapia effluents irrigating cotton l.jpg
Data report vice-versa– Tilapia effluents irrigating cotton

  • Water pH reduced from 8.3 to 8.0

  • Added 19.7 kg/ha total N during one crop.

Olives with aquaculture effluent vice-versa

Olives with well water



Tropical inland integrated systems l.jpg
Tropical Inland Integrated Systems vice-versa

  • Tilapia oil palm, rice, sugar cane


Coastal integrated systems l.jpg
Coastal Integrated Systems vice-versa

  • Shrimp / fish Halophytes and seaweeds

Shrimp and vice-versaSalicornia(halophyte)


Temperate integrated systems l.jpg
Temperate Integrated Systems vice-versa

  • Carp vegetables

  • Catfish soybeans, corn

  • Trout alfalfa, vegetables

  • Aquaponics


Marine integrated systems l.jpg
Marine Integrated Systems vice-versa

  • Salmon kelps, nori, mussels

  • Shrimp seaweeds and oysters

  • Fish seaweeds, bivalves

Why tilapia l.jpg
Why Tilapia ? vice-versa

  • Second most important farmed fish after the carps

  • Most widely grown of any farmed fish

  • In 2007 moved up to fifth most popular seafood in the US


What s needed next l.jpg
What’s needed next? vice-versa

  • Large scale investment

  • Best technologies of ag and aqua

  • Economies of scale

  • Governmental consideration

  • Trained production staff and semi-skilled farming staff
