Abstract. Implementation of agriculturally related early warning systems is fundamental for the management of droughts.Additionally, risk-based approaches are superior in tackling future drought hazards. Due to data-scarcity in many regions, high resolution satellite imagery data are becoming widely used. Focusing on ENSO warm and cold phases, we employ a risk-based 15 approach for drought assessment in the Bolivian Altiplano using satellite imagery data and application of an early warning system. We use a newly established high resolution satellite dataset and test its accuracy as well as performance to similar (but with less resolution) datasets available for the Bolivian Altiplano. It is shown that during the El Niño years (warm ENSO phase), the result is great difference in risk and crop yield. Furthermore, the Normalized Difference Vegetation Index (NDVI) can be used to target specific hot spots on a very local scale. As a consequence, ENSO early warning forecasts as well as 20 possible magnitudes of crop deficits could be established by the government, including an identification of possible hotspots during the growing season. Our approach therefore should not only help in determining the magnitude of assistance needed for farmers on the local scale but also enable a pro-active approach to disaster risk management against droughts that can include economic-related instruments such as insurance as well as risk reduction instruments such as irrigation.

“…The Andean Altiplano is a challenging environment for agriculture due to low rainfall, high evapotranspiration, a short frost-free period, and poor soil fertility (Geerts et al 2006;Garcia et al 2007). High interannual variability in precipitation is a constant feature of this high altitude plateau, due to periodic climate oscillations (e.g.…”

“…The few crops that can tolerate these difficult growing conditions are mainly native roots and grains that have been domesticated by Andean farmers over centuries, including several potato species (e.g. Solanum tuberosum, S. juzepczukii, S. ajanhuiri, and S. curtilobum), quinoa (Chenopodium quinoa), cañahua (Chenopodium pallidicaule), oca (Oxalis tuberosa), papalisa (Ullucus tuberosus), and isaño (Tropaeolum tuberosum) (Garcia et al 2007;Del Castillo et al 2008;MachidaHirano 2015).…”

“…Cañahua, oca, papalisa, and isaño also exhibit high intraspecific variation (Malice and Baudoin 2009;Vargas et al 2011;Velasquez-Milla et al 2011;Mutegi et al 2015). Because of this exceptional diversity, the Andean highlands-and notably the Lake Titicaca region-are recognized as a centre of globally important crop genetic resources (Garcia et al 2007;Velasquez-Milla et al 2011). However, many local varieties have been abandoned in recent years with the intensification of production and associated breakdown of traditional land management and crop rotation systems (Hellin and Higman 2005;Velasquez-Milla et al 2011;Gilles et al 2013;Lennox 2015).…”

Crop diversity is central to traditional risk management practices on the Andean Altiplano and may find renewed importance in adapting to climate change. This study explored the role of crop diversity in farmers' adaptation actions in eight Aymara communities on the northern Bolivian Altiplano. Using a combination of quantitative and qualitative methods, including multifactor analysis and a community resilience selfassessment, we investigated how farmers' use of diversity in adaptation is related to their perceptions of crop and variety tolerances and other environmental, social, and economic factors. Few crops and varieties were perceived as tolerant to increasingly intense and unpredictable drought, frost, hail, and pest and disease outbreaks. Some local crops and varieties were perceived as vulnerable to emerging conditions (e.g. oca, papalisa, isaño), whereas bitter potatoes and wild relatives of quinoa and cañahua were perceived as highly stress tolerant and provide food in harsh periods. A total 19% of households surveyed (N = 193) had introduced new crops or varieties-often disease resistant or early maturing-as an adaptive action. Introduction of commercial crops was a common adaptation action, reflecting farmers' response to warming temperatures and changing economic opportunities, but greater sensitivity of the introduced crops may cause maladaptation. Despite intensification of cropping systems, households continue to maintain a median four potato varieties with different tolerance traits, yet this risk management practice was not perceived as adaptation. Strengthening resilience will require a combination of actions, including maintaining and expanding crop portfolios and restoring soil and ecosystem health, using both traditional and innovative approaches.
