Characterization of palmer drought index as a precursor for drought mitigation
Coping with droughts involves two phases. In the first phase drought susceptibility of a region should be assessed for developing proper additional sources of supply which will be exploited during the course of a drought. The second phase focuses on the issuance of drought warnings and exercising …

Subalpine Forest Tree Seedling Response to Drought
<p>Knowledge of tree species’ ability to tolerate drought is necessary to anticipate future forest dynamics with climate change, especially at the seedling stage given their role in shaping forest structure. We used precipitation reduction shelters to mimic drought for subalpine conifer seedlings …

Conservation Agriculture as an adaptation strategy to drought in Chivi District, Zimbabwe
… This study evaluated CA as an adaptation tool to drought in Chivi district, Zimbabwe. It developed a model to enhance adaptation to drought in Chivi and other areas of similar environment. The VLIR-UOUS (2019) Theory of Change (ToC) principles structured interview checklist was used to review the …

Adapting a hazards-risk model to water scarcity in rural India : Aurangabad case study
… block was selected as a case study due to its drought effects and high water tanker usage in the past five years. This thesis develops a disaster risk metric for water scarcity, using an analysis of potential hazards, socioeconomic vulnerability, and policy responses to assign a "disaster risk …

Linking groundwater level fluctuations and water quality to vegetation and habitat condition in blanket bog ecosystems in Ireland
… from the peat with precipitation after prolonged drought. Effects of deterioration in water quality and flow regimes are apparent with anthropogenic alteration of peatlands. Vegetation mapping demonstrated that blanket bog ecosystems consist of a mosaic of different vegetation …

Drought Monitoring with Remote Sensing Based Land Surface Phenology Applications and Validation
Droughts are a recurrent part of our climate, and are still considered to be one of the most complex and least understood of all natural hazards in terms of their impact on the environment. In recent years drought has become more common and more severe across the world. For more than a decade, the …

Effects of climate change on plants and ecosystem functioning : Implications for managed temperate grasslands
… of the existing studies investigated the effects of climate change on productivity. However, studies on how climate change (such as 1000-year drought, high precipitation variability, seasonal warming, late frost in spring etc.) affects flowering phenology, plant physiology, community …

The combined effects of fertilization and relative water limitation on tissue water relations, hydraulic parameters and shallow root distribution in loblolly pine (Pinus taeda L.)
… parameters classically characterized in drought response studies. More severe water limitation was necessary to elicit responses, and those responses had not been fully described previously. The more severe water limitation resulted in increased capacitance beyond turgor loss, increased …

THERE IS NO PLANET B(EE): AN INTEGRATED APPROACH TO UNDERSTANDING DRIVERS OF POTENTIAL DECLINES IN BUMBLEBEE COMMUNITIES
… impacts to forager efficiency may have long term effects on hive development and reproduction that relates to the specific plant stress encountered in the field. These results demonstrate the direct effects of climate change associated plant stress on B. impatiens and provide a measurable trait, …

Impact of extreme hydrological conditions on belowground carbon cycling and redox dynamics in peat soils from a northern temperate fen
… the general consensus regarding the broad effects of drying and flooding on CO2 and CH4 exchange, belowground processes producing such greenhouse gases and their response to water table dynamics is underrepresented and usually simplified or overgeneralized. Temperature, moisture, oxygen …

Modelling the economic and social consequences of drought under future projections of climate change
Drought events and their consequences pose a considerable problem for governments, businesses and individuals. Superimposed on this risk is the danger of future anthropogenic climate change. Climate models are increasingly being used to understand how climate change may affect future drought …
