Cognitive Droughts

SSRN Electronic Journal, 2020
Poverty involves both low income levels and high income uncertainty. Do both these dimensions of being poor capture attention in ways that distort decision-making and trap people in poverty? We examine these issues using real-life shocks faced by farmers in Brazil: random payday variation affecting income levels, and rainfall shocks that affect income ...

Streamflow drought: implication of drought definitions and its application for drought forecasting [PDF]

Hydrology and Earth System Sciences, 2020
Abstract. Streamflow drought forecasting is a key element of contemporary drought early warning systems (DEWS). The term streamflow drought forecasting (not streamflow forecasting), however, has created confusion within the scientific hydrometeorological community as well as in operational weather and water management services.
