Geographic Targeting for Diagnostic of Banana Fusarium Wilt

5,406 views

Published on

Using ArcGIS Desktop we applied different criteria to select a group a 149 farms to conduct the first stage of a study in San Luis de Shuaro, Peru. Due to access difficulties found on this region, the study would have been much more difficult and cost much more in terms of resource allocation had we been unable to utilize GIS.

  2. 2. Presentation outline • What is Bioversity International • What is Fusarium Wilt • Work description – Geographic Targetting • Results • Conclusions
  3. 3. Bioversity International Bioversity International is a research-for-development organization seeking solutions to global issues through the use and conservation of agricultural and forest biodiversity.
  4. 4. Our Vision Our vision is a world in which smallholder farming communities in developing countries are thriving and sustainable.
  5. 5. Our purpose Using and conserving agricultural and forest biodiversity for… Livelihoods Nutrition Sustainability Productive & Resilient Ecosystems
  6. 6. Our global reach We work in areas of significant levels of rural poverty where very often the world’s remaining biodiversity is found. We focus on rain-fed farming systems, primarily managed by smallholder farmers, in areas where large- scale monoculture is not a viable option.
  7. 7. What is Banana Fusarium Wilt? - Also known as “Panama Disease” - Soilborne fungal disease caused by the fungus Fusarium oxysporum f. sp. cubense - It blocks the pass of nutrients from roots to the rest of the plant - Fungus can persist in soil for decades and cannot be managed using chemical pesticides Source: ProMusa For mor information visit: www.promusa.org

  19. 19. Results - 76 Farms selected (Total) - 60 Farms with Fusarium Wilt presence - 16 Farms without Fusarium Wilt - Visualization of Spatial Distribution • Fusarium Wilt • Production System
  20. 20. Conclusions - ArcGIS Desktop was a key tool defining the target farms - Farms targeting was traduced into a more efficient resource allocation - Visualization of the spatial distribution allows to outline study hypothesis
