3. The protein challenge
 World population 2050: +33%
Global meat consumption 2030: +50%
 3-6 kg plant protein required for 1 kg meat protein
Urgent need for an increase in plant protein production

4. Protein sources for animal production
 Current global need for feed protein: 1 billion tonnes per year
 Major current source: soybean

5. Protein sources for animal production
 Extension of soybean production?
● Greater demand of land and fresh water
● Loss of biodiversity
● Further distorted nutrient balance
 Alternative protein source: seaweed
● Use of seas and oceans
● No fresh water required

6. Brown seaweeds
2.000 species
Green seaweeds
1.200 species
Red seaweeds 6.000 species

10. Seaweed research under laboratory and greenhouse conditions

11. Test location The Wierderij
 Crop cultivation of seaweed

13. First-year seaweed production at The Wierderij
Year-round production: the combination of green and brown seaweeds yielded 25,000 kg dry weight/ha.

14. Prospects for seaweed cultivation in the Middle East
Gracilaria
multipartita
Eucheuma
cottonii
Ulva lactuca

15. Gracilaria multipartita
Productive in tropical seas such as the Red Sea and the Arabian Gulf
Production system is not yet optimised

16. Eucheuma cottonii
Productive, but susceptible to diseases
Production system is not yet optimised

17. Ulva lactuca
Grows well in warm sea water
25% of DW is high value protein
Production system is not yet optimised

18. Prospects for seaweed cultivation in the Middle East
Gracilaria
multipartita
Eucheuma cottonii
Ulva lactuca
Gracilaria, Eucheuma and Ulva cultivated in an integrated year-round system may be a sustainable production system

19. Profitability of seaweed cultivation
Benefits (AED per ha) Carbohydrates 50,000 Proteins-food (20%) 25,000 Proteins-feed (80%) 15,000 PUFAs 6,250 Total 96,250
Annual yield of 25,000 kg dry weight per ha
10,000 kg carbohydrates
5,000 kg proteins 625 kg PUFAs

20. R&D challenges
 Production of propagation material
 Construction of robust, but flexible, production facilities
 Development of site-specific sustainable production systems
 Development of efficient harvesting technology
 Development of cost-efficient upstream production chains
