increased though time ( Changnon et al. 2000 ; Bouwer 2011 ; Field et al. 2012 ). Uncovering and quantifying the source(s) of these trends is an area of continual dialogue and controversy in hazard assessment research (e.g., Trenberth et al. 2011 ; Kunkel et al. 2013 ), largely because of the inadequacies of current geophysical event and socioeconomic datasets ( Kunkel et al. 1999 ; Höppe and Pielke 2006 ; Lerner-Lam 2007 ; Bouwer 2011 ; Kahn and Kelman 2012 ). However, certainties do exist

institutional responses to late-twentieth-century drought The Sahel reached its current prominence in the study of human–environment interactions because of the well-documented environmental crisis that occurred with the abrupt onset and persistence of multiyear drought in the late 1960s ( Glantz 1977 ). Persistent drought led to widespread food insecurity into the 1970s and 1980s, with acute episodes during 1968–73 and 1982–84 causing significant human loss. The climatic shift from wet conditions in the

-time data, which is difficult to collect via mainstream surveys, at least in the current environment. As such, researchers have directed their efforts toward the development of a new suite of tools that leverage the massive amount of information that members of the public transmit and/or broadcast via social media to measure fluctuations of public attention. The logic underlying such measures is rather simple—the more people talk about a particular issue, topic, or hazard (via Twitter, Facebook, Google

international and national markets (e.g., milk, meat). Finally, noncapitalized farmers (21% of the sample in Junín and 38% in San Justo) organize their production exclusively on their own lands since the current increase in land rental prices excludes them from the real estate market. Most of the properties are smaller than 200 ha. These farmers may or may not hire third-party services—agriculture machinery is usually too expensive to purchase, so they manage old or refurbished mechanical equipment
