Veronika Miranda Chase - Rock Powders: Nourishing Soils, Biodiversity and People

  1. 1. Remineralization and Agroforestry Addressing Climate Challenges and Improving Social Conditions V. Miranda Chase Research Associate Remineralize the Earth Restoring Ecosystems to Reverse Global Warming Biodiversity for a Livable Climate Tufts University, November 22, 2014
  2. 2. How to tackle Complex Problems? Complex Issues: • Climate Change • Hunger and Poverty • Job creation and Income generation • Energy and Food Security The Triple Bottom-Line Approach: • Social, Environmental and Economic Sustainability • Integrated and holist perspective
  3. 3. What is Agroforestry? Mixed-use land management system, that combines agriculture and forestry practices in order to create more diverse, productive, profitable, healthy, and sustainable land-use systems. • Diverse intercropping of species • First harvest can come as early as a few weeks • Plant succession: Herbs and spices vegetables fruits hard wood
  4. 4. What is Agroforestry?
  5. 5. What is Remineralization? • Remineralization is a fertilization technique that uses rock powders to rejuvenate depleted soils, restoring healthy conditions without disturbing natural ecosystems. • Rock powders can be used as substitutes for chemical fertilizers and pesticides. Remineralization is also a “Triple Bottom Line Solution” to issues of food security, erosion, forest management and climate change.
  6. 6. What is Remineralization?
  7. 7. Advantages of Agroforestry • Water Savings due to less evapotranspiration (greater soil coverage). • Require less fertilizers (the plants naturally supply each other with key nutrients). • Resembles natural ecosystems, protecting biodiversity and producing natural goods and ecosystem services.
  8. 8. Advantages of Agroforestry Galbert et. al. (2013).
  9. 9. Advantages of Agroforestry Galbert et. al. (2013).
  10. 10. Advantages of Agroforestry • Trees can be used for shelter, biofuels and medicinal purposes. • It can be easily combined with other sustainable agricultural techniques, e.g. Remineralization, Biochar, Compost, Organics, etc.
  11. 11. Advantages of Remineralization • Provides slow, natural release of elements and trace minerals. • Rebalances soil pH. • Increases earthworm activity and the growth of microorganisms. • Builds humus complex. • Prevents soil erosion. • Increases the storage capacity of the soil. • Decreases dependence on fertilizers, pesticides, and herbicides.
  12. 12. Advantages of Remineralization Goreau et. al (2011)
  13. 13. Advantages of Remineralization • Increases the nutrient intake of plants. • Increases yields and gives higher brix reading. • Increases resistance to insects, disease, frost, and drought. • Produces more nutritious crops. • Enhances flavor in crops and shelf life.
  14. 14. Remineralization Uses Bioremediation Dairy & Livestock Carbon Sequestration Pest Control Stabilizing the Climate
  15. 15. Historical Perspective on Remineralization
  16. 16. How it Works Case Studies: • The Tucurui Dam in the Amazon Basin • The APACA Community Projet in Bahia, Brazil • The Savannah project in Brasilia, Brazil • The Costa Rica model (Food, Fuel and Income) • The Panama project
  17. 17. Case Studies- Tucurui Dam
  18. 18. Case Studies- Tucurui Dam
  19. 19. Case Studies- Bahia (Brazil)
  20. 20. Case Studies- Bahia (Brazil)
  21. 21. Case Studies- Brasilia (Brazil) Two views of a private Agroforestry initiative
  22. 22. Case Studies- Costa Rica
  23. 23. Case Studies- Costa Rica More than 1600 trees were planted Jatropha- Biofuel tree This model can be transferred to other poor countries and yield social and environmental benefits, such as replacing firewood harvesting.
  24. 24. Case Studies- Panama
  25. 25. Case Studies- Panama • No fertilizers were added • This tree fixes nitrogen • Rock weather by roots provides a sink of atmospheric CO2 Goreau et. al (2011)
