| The goal of this study is to empirically evaluate the extent to which agricultural productivity estimates are affected by variation on climate. To do so, we explore the case of the agricultural sector in the Southeast US. This geographical region is influenced seasonally by the El Niño Southern Oscillation (ENSO) phenomena making it ideal for studying the interaction of climate variability and agricultural productivity. Although, different methodologies have been developed to study TE the stochastic production frontier (SPF) approach offers several advantages over other available alternatives (Kumbhakar and Lovell 2003). Thus, to assess the impact of climatic on TE we estimate alternative SPF models with and without climatic variables. We also test... |

| Production strategies pursued by households and individuals in a peasant community of the Bolivian Altiplano are shaped by access to resources, social networks and institutions, wealth, and the ability to develop urban rural linkages. In times of climatic stress such as the low rainfall of 1995, the household economic portfolio shifts to activities less vulnerable to climate. The ability to shift is conditioned by access to resources, social capital, stage in the life cycle and wealth. Atypology developed to understand how strategies take shape during a drought is used to evaluate access to information during el Nino (1997-98) and impacts on potato production in 1998-99. The relationship between diversification and use of climate forecasts (local and... |
