  1. Adaptationto climate change in the coldtropics: challengesfrom the Andes Bert De Bièvre, CONDESAN UNFCCC TEC Workshopon Technologies for Adaptation, Bonn, 4 March 2014

  2. The Tropical Andes

  3. Climate Change in the Andes : vertical altitudinal movescertain, everythingelseveryuncertain

  4. Water for Quito: Municipal Water Companypurchased 15000 ha of degraded paramo Quito Antisanavolcano Cotopaxi volcano

  5. Gostraightto the point • What do peopleappreciateaboutwatersources in mountains, wherestorage in reservoirsislimited? • Water Regulationcapacity • Glacier retreat = loss of waterregulationcapacity • Paramos sufferalso of loss of waterregulationcapacity (less visible, but at catchmentscale more important!) • Adaptationtechnology = conserve orrecoverwaterregulationcapacity of paramos • Restauration ≠ Reforestaton !

  6. Experimental restaurationplots

  7. Experimental restaurationplotsonheavilydegraded paramo

  8. Monitoring: scales! • Plotscale: • Plantdiversity • Vegetativecover • Soilhydrophysicalproperties • After 2 yearsevaluationwhichplotstocontinue • Microcatchmentscale: • Rainfall – flowrelation in pairedcatchmentswithdifferenttreatments • First 2 years= baseline, thenselectedrestaurationpracticesupscaledtomicrocatchmentscale, and monitored

  9. Monitoring • Monitoring of Climate Change ≠ Monitoring of adaptationmeasure! • Monitoring of adaptationtechnologyis for • adaptivemanagement/optimization of the technology • providingevidence of itsimpact • Insight in upscalabality/outscalability • Likewithintegratedcatchmentmanagement in general, thereis a general lack of evidence of hydrologicalbenefits of implementedtechnologies, incl. Indigenous/traditional • Need for development of indicators/languagetodiscussthesebenefits

  10. Conclusions: Gaps and Challenges • Logicalconnection: whichlostecosystemservicesto be replacedbywhichadaptationtechnology? • Change in hydrologicalmonitoringparadigm • Lack of effectivity/evidence base of integratedcatchmentmanagementmeasures, applies for climate change adaptation • Thereforehugeneed for traingsubnationalgovernments and otherstakeholders • AppropiateIndicators/language for discussion of benefits • Technologies not “onesizefitsall”, they are specificto climate, hydrology, soils, precedentcondition, … • South-South exchangebetween Mountain regions in the worldveryeffective, even in expensive (coordinationstructures do exist)
