Such tools require the establishment of reference systems to provide comparative ‘baseline’ or ‘normal’ values. In this study, we measured the spatial and seasonal variability of eight biological indicators (including two...
Ecosystem recovery indicators as decision criteria on potential reduction of fallow periods in swidden systems of Northern Thailand
###RSS_DATE###
Publication date: December 2018Source: Ecological Indicators, Volume 95, Part 1Author(s): K. Tongkoom, C. Marohn, H.P. Piepho, G. CadischAbstractCrop rotations in today’s swidden systems of Northern Thailand typically include five to ten years of fallow. Regarding ecosystem functions, these systems are relatively close to secondary forests when compared to modern agricultural systems; but they are under pressure for intensification, i.e. shortened fallow periods. In general, criteria are needed to decide whether fallow duration can be reduced, safeguarding ecosystem restoration and...
An ecosystem service-disservice ratio: Using composite indicators to assess the net benefits of urban trees
###RSS_DATE###
Publication date: December 2018Source: Ecological Indicators, Volume 95, Part 1Author(s): Andrew Speak, Francisco J. Escobedo, Alessio Russo, Stefan ZerbeAbstractConsidering ecosystem disservices (EDS) of urban forests alongside the services (ES) can lead to better-informed decisions about tree species selection and placement in cities. Finding a common assessment framework, that does not rely on a financial model, can be tricky, and many studies consider, but do not include, EDS in their tree appraisals. Compound indicators represent a means to neatly combine disparate ecosystem data into...
