Household Economic Portfolio and Livelihood Strategies

  • Bolivia

    Currently on the second year of activities in Bolivia (August 2000-July 2001), a profile of potential users is being developed using as a data base a household survey that elicits information on household production strategies, income generation activities and access to forecast information for agricultural activities.  Data was collected at the end of 1999 and 2000.  The first data set was analyzed, and economic portfolios with varying degrees of vulnerability to drought were identified.  Currently data on the second year is being analyzed to compare changes in livelihood strategies through time and by groups of families. Outputs from this research activity are listed in the list of publications.  Some are available on line  Specific articles can be requested from

  • Peru

    Research in a second site, following the same theoretical framework developed for the Altiplano started in September of 2000.  Specific hypothesis were developed for this research site.  A first questionnaire on household resources, production consumption and income generating activities elicited information of 102 families for the 1999-2000 agricultural calendar.  The survey was applied between October 2000 and February of 2001.  Access to information and participation and networks were included in the survey, as well as households perceptions of the El Niño Event of 1997-98.  The data is currently being processed to determine if a typology of household livelihood strategies (On line publications) similar to the one constructed for the Bolivian Altiplano can be developed with cluster analysis.  An important question that will be addressed in Peru is the role of transactions costs and networks in accessing information.







Local Knowledge and Climate Forecasts: Networks and access to information

  • Bolivia

    The second year of research in Bolivia concentrates on local forecasts and identifying the type of information that producers regard as useful for household agricultural and economic decisions.  An household activities and agricultural calendar that focuses on timing (local indicators and signals for decisions) and the windows of opportunity for these decisions is being constructed.  A study of networks and diffusion of local forecasts in the community and between the community and outside institutions is underway.  Nodes of information appear to be local and related to specific agricultural activities.  This research activity will be completed in July for Bolivia.

  • Peru

    A first review of the literature for the Puno region was undertaken by Claverias (publication available on line).  Currently a survey is eliciting information on local forecasts in two communities of Puno, both agropastoral and Aymara.  A replication of the study on networks will take place at both sites during the third year of the research project, second in Peru.









Potatoes and climate variability: Introduced varieties in an Altiplano Community

Addressing the question, "Are there technologies available for years of drought or frost that would allow farmers to make use of information on forecasts?", a research activity was conducted in collaboration with PROINPA to assess with farmers varieties that tolerate frosts or low rainfall.  A study of livelihoods and the role of potato will be completed in July (M Sc Ag Economics, Susan Materer).  One of the factors affecting the role and dedication to potato production and consumption in the Altiplano is a function of the characteristics of the economic portfolio managed by the household.  A common role in livelihoods dealing with climatic perturbations is the role of chuño, which acts as a measure of ability to cope from year to year.











Biological Models for Impact Assessment in the Andes

Researchers in the region under the lead of CIP are calibrating models that will be used to measure the impact of droughts and frosts on the economic portfolios of the different groups identified.  The groups differ in livelihood strategies and vulnerability differs as a function of the activities in which they are engage which related to access to resources, life cycle, and "exogenous" factors.  Progress in the calibration of models can be viewed in the second annual report appendix (please note this is a very large file).

Expert Panels

Every year an expert panel is held near one of the research sites. The First Expert Panel (See Publications for Workshop in the list of presentations) took place July 2000.  The second one is  planned for the second week of July 2001.  These panels provide an opportunity to review on going research activities, as well as identify areas that should be pursued, and that were not considered in the original plan of work.  It provides an opportunity to build linkages with organizations that work in the areas of early warning in agriculture and food security.
