Evaluating Adaptive Capacity to Climatic Extremes in Rural Zambia
… quasi-experiment to evaluate the impact of drought exposure on yields and the mitigating effects of Sustainable Land Management Practices (SLMs) using the matched Difference-in-Differences and triple difference estimation strategies respectively. The results show that severe drought exposure …

Aspirations, drought, and the perception of weather: How are future goals affected by severe rainfall shocks?
… setting. Particularly, we seek to understand how droughts impact individual aspirations. This report also makes the important distinction between perceived, actual, and expected drought shocks, and identifies the various influences on goal-setting. Using data on 748 Zambian households, we show …

Beyond productivity- Effects of extreme weather events on ecosystem processes and biotic interactions
… extreme weather events, such as heat waves, drought or heavy rain spells, are projected to increase in magnitude and frequency. As these may affect vegetation and ecosystems more than gradual shifts in mean climatic parameters, investigating the consequences of extreme weather events recently …

Impacts of climate change on herbivore induced plant signaling and defenses
… altered. To examine the impact of elevated CO2 exposure on susceptibility to herbivory in soybeans in more detail, the magnitude and timing of transcripts related to three major hormone signaling pathways (jasmonic acid [JA], salicylic acid [SA], ethylene [ET]) and related defenses were examined …

Climate change in experimental ecology - The impact of warming and drought on key European tree, heath, and grassland species
… will be accompanied by climatic extremes such as drought. The frequency and magnitude of those extreme weather events are expected to increase in the future. Additionally, climatic extremes may have stronger effects on plants than a gradual temperature shift. Therefore, investigations of plant …

Social safety nets in presence of weather shocks: three essays on development economics from village economies in Kenya
… In the chapter two, we examine the effects of exposure to drought on child health and ask whether receipt of social safety net, in the form of HSNP cash transfer, could help poor households mitigate the negative effects of drought. Evidence from this study show that children residing in HSNP …
