A Risky Climate for Southern African Hydro [PDF]

, 2012
This in-depth study of the hydrological risks to hydropower dams on the Zambezi River gives an early warning about what Southern Africa could be facing as it contemplates plans for more large hydropower dams in a time of climate change.Currently, 13,000 ...

Vegetation on the move: elevational shifts and greening dynamics across the Himalayan alpine zone

Ecography, EarlyView.
This study investigates alpine ‘vegetation line' (the upper limit of continuous plant community) dynamics in the Himalayan alpine zone (HAZ) over a 24‐year timescale (1999–2022) using maximum NDVI products derived from Landsat series datasets, adjusted for sampling bias using phenological modelling.

Study on Response Probability of Meteorological and Hydrological Drought Characteristics during Drought Recovery Period in Upper Hanjiang River

Renmin Zhujiang
It is of great reference significance for drought recovery and water resources management to explore the response rules of meteorological and hydrological drought characteristics during the drought recovery period.

Hydrological drought response to meteorological drought in the Iberian Peninsula [PDF]

Climate Research, 2013
In this study we assessed the impact of meteorological droughts on streamflow droughts in 187 river basins of the Iberian Peninsula. For each basin we correlated the 1 mo to 48 mo standardized precipitation index (SPI) with the standardized streamflow index to assess the response time of streamflow droughts to the SPI, and to determine the best ...

Policy Integration for Enabling Environments: Decentralised Water Technologies for Rural Water Reuse

Environmental Policy and Governance, EarlyView.
ABSTRACT Water reuse holds significant promise for addressing global water challenges, yet wide scale implementation remains limited. Decentralised water technologies for reuse have been highlighted as a potential aide in the reduction of water challenges, specifically for environments that have typically been considered ‘water rich’, and in rural ...

Drought propagation in karst and non-karst regions in Southwest China compared on a daily scale

Journal of Hydrology: Regional Studies
Study region: Three subbasins with different karstification degrees in Southwest China. Study focus: To investigate the mechanism of karst influence on drought propagation, this paper used a daily-scale threshold level method to identify drought events ...

When Policy Is the Hazard: Institutional Legitimacy and Climate Risk Attribution Among Farmers in Water Stressed California

Environmental Policy and Governance, EarlyView.
ABSTRACT This study examines how farmers perceive and respond to climate policy risk in the context of drought and argues that understanding such responses is as important as understanding farmer reactions to the biophysical impacts of climate change.

Using SIMGRO for drought analysis – as demonstrated for the Taquari Basin, Brazil [PDF]

Tools were developed and tested to quantify space–time development of droughts at the river basin scale. The spatial development of a hydrological drought in river basins brings different challenges to describe drought characteristics, such as: area in a

The importance of periodic droughts for maintaining diversity in the freshwater environment [PDF]

, 1996
Whereas some species may rely on periodic drought conditions for part of their life histories, or have life strategies suited to exploiting the habitat or changed environmental conditions that are created by drought, for other organisms it is a time of ...

Climate change effects on biomass and greenhouse gas emissions are ameliorated by nontoxic endophytes in southeastern USA transition zone tall fescue pastures

Grassland Research, EarlyView.
Tall fescue produces more biomass and less carbon dioxide from the soil when it contains its beneficial fungal endophyte. Increased temperatures projected with climate change reduce fescue biomass, while altered rainfall frequency does not. Altering rainfall frequency and increasing temperatures can reduce carbon dioxide emissions from soil.
