Livestock production and climate change: towards sustainable production with smaller environmental footprints:


Published on

the Produção Integrada de Sistemas Agropecuários (PISA) System in Brazil, by Paulo César F Carvalho, Professor at Federal University of Rio Grande do Sul


The International Symposium on Sustainable Food Systems for Healthy Diets and Improved Nutrition was jointly held by FAO and WHO in December 2016 to explore policies and programme options for shaping the food systems in ways that deliver foods for a healthy diet, focusing on concrete country experiences and challenges. This Symposium waas the first large-scale contribution under the UN Decade of Action for Nutrition 2016-2025. This presentation was part of Parallel session 1.1: Sustainable agriculture production and diversification for healthy diets"

Livestock production and climate change: towards sustainable production with smaller environmental footprints:

  1. 1. Livestock Production and Climate Change: towards sustainable production with smaller environmental footprint: Paulo César de Faccio Carvalho The PISA System in Brazil
  2. 2. Public-private initiative led by the Brazilian Ministry of Agriculture “A sustainable intensification production model oriented to increase food production at farm and landscape levels based on sustainability pillars” GOOD FARMING PRACTICES
  3. 3. P I S A Production Integrated Systems Agriculture ✓one shaping principle: the interdependence between healthy diets and the social and environmental sustainability of the food system Nutrition Livestock Production
  4. 4. Farmers apply voluntarily Universities are responsible for proposed technologies management interventions implemented 3 years project Local RAS (local empowerment) Donors Private consultants (extension services)
  5. 5. ~1050 small stakeholders ~30 municipalities small dairy farmers 14 lactating cows ~150 litres total daily milk production Challenges: dependence on external inputs, low income, labour intensive, environmental footprint, ageing farmer population, industry demands for scale. Southern Brazil
  6. 6. Crop succession planning Sound grazing management Soil health Targeted interventions/ technologies Diminished costs Enhanced quality of life No till Reduced labour Strategy: use locally available resources Holistic approach Farm finance management Resource use efficiency
  7. 7. The social impact on those communities is simply huge! *end of 1st year Milk yield per cow incresases by 30% Reduces feeding by 20%* Amount of milk produced per unit feeding concentrate increases from 1.9 to 4.2 kg Number of lactating cows increases from ~14 to 19* Annual milk yield increases from 4,800 to 11,250 kg.ha-1 IMPACT MORE
  8. 8. Before PISA After PISA Range Somatic cell counts - cfu/mL 250.000 20.000 - 88 % Total bacteria counts - cfu/mL 650.000 200.000 - 70 % Towards healthy diets… Milk from grazing-based production systems has less saturated and more n-3 PUFA and CLAc9t11 which is beneficial for health. The occurrence of natural trans FA (t11) in milk predominates whereas intensive feeding practices enhance t10-FA, with possible negative health effects (Elgersma, A. 2015. Eur. J. Lip. Sci. Tech).
  9. 9. Each Us$ 1.00 invested on PISA Generates ~Us$ 6.00 in income How much? Means ~Us$ 1,500 / smallholder / year (6 private meetings + 6 group meetings)
  10. 10. International reference for assessing trade-offs and synergies between all dimensions of sustainability 494 farms already assessed Sustainability Assessment of Food and Agriculture systems (SAFA)
