1 Promising Sustainable Beef Catalyse continuous Improvements Martin C. Th. Scholten

2 GRSB Principles Natural Resources People & Community Animal Health & Welfare Food Efficiency & Innovation

3 GRSB 2016; breakouts What is the consumers commitment to sustainability? Expecting Integrity (Trust) What is the business commitment to sustainability? Building Chain of Custody (Transparency) How to assess the sustainability? Non-linear, kaleidoscopic Assessments (Fair & Full)

4 GRSB 2016; breakouts How to practice sustainability? Convincing Progress (Footprints, Deforestation) What is the NGO commitment to sustainable practices? Critically supportive for Actions more than Words

5 Consumers Expecting Integrity Key Note Dr. David Hughes But do not buy that! Beef is Premium... Margin is in Adjectives Xxx-Free is Hype Deforestation is a No-Go Health is a Debate

6 Business strives for a Chain of Custody Field Farm Abattoir Processing Retail Consumer

7 Best Practice requires Best Science Fair Assessment Full Assessment Action Driven Assessment Resource & Land Use Animal Health & Welfare Local Specifications

8 Most LCA s are too simplistic & not provocative Linear summing up LCA s single products From linear considered commodity/supply chains Addressing single topics of concern Do not account a Globally integrated AgroFood-system Ignores variation in Feed for Food Footprint Do not envisage feed strategies & grazing regimes Do not envisage optimal land use Depends on scope and scale

9 The Wageningen Animal Sustainability Team Imke de Boer Maximum Production of Human Edible Proteins per Hectare of Land without Depletion of Productivity and Biodiversity Marion de Vries Corina van Middelaar Hannah van Zanten Eddie Bokkers

10 Variation in Land Use among Systems 250 m 2 /kg edible protein Chicken Pork Beef Milk Egg De Vries and De Boer 2010

11 First Analysis of Systems (1) Calf from beef herd Calf from dairy herd

12 Calf from Dairy vs Beef

13 First Analysis of Systems (2) Pasture-finished Concentrate-finished

14 Concentrate Finished versus Pasture Finished

15 Competition between Humans and Animals Accounting for competition between humans and animals for land might be in favour of pasture-finished beef

16 Direct Competition 30 % 40 % World grain production World arable land

17 Indirect Competition X yes no Agricultural land Marginal land

18 Feed-Food Competition Research Question How much animal source food can we eat while avoiding feed-food competition?

19 Land use, etc. Hockeystick Figure Threshold point % Consumption ASF

20 Land use etc. Production Sustainable Intensification % Consumption ASF

21 Land use etc. Sustainable Diet Consumption % Consumption ASF

22 Land use, etc. Efficiency of the Food System 7-27 g % Consumption ASF

23 For the Situation in the Netherlands

24 The Food Production Cycle in a Biobased Society

25 Room for Improvement: Feed Digestibility Feed Digestibility (%) Number of Cows (Miljons) Gerber et al., 2013

26 Digestibility & Protein Content Feed Stocks Feedstock Digestible Energy (%) Proteins (g N / kg) Rye Grass Concentrates Maiz Silages Other grasses Crop residuals

27 Upgrading Low-DE Feed Stocks by Mushrooms 70% 60% 50% 40% 30% 20% 10% Reduction Cel Reduction Lignin 0% -10% Wheat Straw Rice Straw Maize Stover Bagasse Oil Palm Fronds Wood Chips

28 Room for Improvement: Manure = Product Minerals & Energy Waste Management Organic Matter & Biota Soil Quality Biologicals & Fine Chemicals

29 Room for Improvement: Freeze the Footprint Genotyping low methane production for selection Improving feed quality and digestibility, rumen microbes Improving animal health and husbandry conditions Manure management: collection, storage and utilisation Improving C sequestration soils Precision Livestock Farming

30 Soil Organic Matter Matters!

31 Challenge: SDG Role of Beef Cattle

32 Think Global, Act Local, Around the Globe

33 Observations based Recommendations Enrolling Performance Catalyse continuous Improvements Anticipate on Trends, means Awareness of Regime Shifts Set SDG based transition Goals and challenging Claims Think in Systems, Circularities and Innovations Redefine the concept of Efficiency Build Capabilities in developing Countries

34 Trust the Farmer? Support the Farmers to Foster the Animals & Soils
