Presentacion de impactos esperados de cambio climatico en los Andes. Presentado por Andy Jarvis en Lima el 15 de septiembre de 2009 en el "Worskshop on Integrated Space Technologies Applications for Sustainable Development in the Mountain Regions of Andean Countries" en CONIDA, Lima, Peru.
24. Climas mueven hacia arriba Temperatura media reduce por 0.51 o C por cada 100m en la zona cafetero. Un cambio de 2.2 o C equivale a una diferencia de 440m.
33. Impact of climate change on cassava suitable environments Global cassava suitability will increase 5.1% on average by 2050… but many areas of Latin America suffer negative impacts
34. …… .and for Latin America? Drought or flooding tolerance 30% of current cassava fields would benefit from enhanced drought or flooding tolerance 1.6m Ha still suffering climatic constraint 2.23m Ha of current production 2.1m Ha of new land would become suitable for cassava
35. Evaluating Technology Options: Crop Improvement for Cassava Grey areas would get no benefit from drought or flood tolerance. Blue areas benefit from drought tolerance improvement Purple areas benefit from flood tolerance improvement
How are we going to estimate the effects of climate change on agriculture unless we’re going to wait for it to happen? Past changes are not really a good estimator. The little ice age starting in 1450 or thereabouts was a major event, completely changing the life styles and agriculture in Europe. It is piddling compared with what we are likely to see in the next 20 to 50 years. We must therefore rely on modeling situations that we have never before seen.
Reducir la información, pasar gráficos a otra diapositiva pues no se aprecian Hay mucho texto. El cuadro no es funcional a una presentación, por el tamaño de tipografía y la naturaleza de la información. Sería preferible un gráfico de barras verticales con los principales cultivos.
