The significance of local water resources captured in small reservoirs for crop production – A global-scale analysis [PDF]

open access: yes, 2010
Rainwater harvesting, broadly defined as the collection and storage of surface runoff, has a long history in supplying water for agricultural purposes. Despite its significance, rainwater harvesting in small reservoirs has previously been overlooked in ...

Characterisation of Drought and Wet Events in the Paraíba do Sul River Basin—Brazil

open access: yesInternational Journal of Climatology, EarlyView.
Trend analysis identified statistically significant reductions in precipitation (at the 5% significance level) at specific pluviometric stations in São Paulo and Rio de Janeiro, while other areas, mainly in Minas Gerais, experienced significant increases in annual and seasonal rainfall, particularly during summer and spring. These significant trends at

Spatial modeling for detection of water retention capacity in technosols developed on carboniferous spoil heap after hard coal mining

open access: yesEcological Informatics
Post-industrial areas, such as heaps, are an Anthropocene pressure on the environment but show natural potential for new ecosystem services, i.e., water retention, biodiversity, and C-sequestration.

Decoupling climate and human impacts on the nitrogen cycle during the Irish Bronze Age

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Disentangling climate variability and human activity in past nitrogen cycling is key to understanding ecosystems. Previous studies in Ireland observed a widespread, permanent shift in terrestrial nitrogen cycling during Later Prehistory, potentially linked to intensifying land‐use.

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

open access: yes, 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 ...

Comparing autumn duck use of intensely managed wetlands in Michigan using a novel approach

open access: yesThe Journal of Wildlife Management, EarlyView.
Camera traps, a relatively novel method for assessing waterfowl use of wetlands, show ducks in southeastern Michigan are influenced by hunting disturbance, vegetation type, season progression, and diel period. Abstract Socioeconomic value derived from duck hunting has contributed to autumn habitat use becoming a particular focus for the natural ...

Wildfires' Cost for Societal Welfare: Economic Evaluation of Forestry Ecosystem Services Losses in Southern Italy

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Forest ecosystem services (ESs) are garnering increasing public attention as awareness grows regarding society's fundamental dependence on them for well‐being. Forest fires, one of the major disturbances of ESs, are becoming more frequent and destructive, exacerbated in part by climate change.
