Synthesis on bioeconomy monitoring systems in the EU Member States – indicators for monitoring the progress of bioeconomy

This report presents an overview of existing bioeconomy strategies, policies or related initiatives and indicators to monitor and assess these at EU MS level, and the importance of existing bioeconomy sectors at national level. Furthermore, it presents the existing or needed most suitable bioeconomy key indicators and related indicators, and their respective data availability, for assessing and monitoring the progress of a bioeconomy at national level. The identified most suitable bioeconomy indicators important and feasible at the national context, can contribute to the further discussions when setting the frame for the development of a common EU bioeconomy monitoring system.

Functional diversity underlies demographic responses to environmental variation in European forests

Biodiversity loss and climate-driven ecosystem modification are leading to substantial changes in forest structure and function. However, the effects of diversity on demographic responses to the environment are poorly understood. We sought to determine whether functional diversity underlies demographic responses to environmental variation in European forests.

Oxygen stable isotope ratios from British oak tree-rings provide a strong and consistent record of past changes in summer rainfall

The isotope-based rainfall signal is stronger and much more stable over time than reconstructions based upon oak ring widths. Using recently developed methods that are precise, efficient and highly cost-effective it is possible to measure both carbon (δ13C) and oxygen (δ18O) isotope ratios simultaneously from the same tree-ring cellulose. In our study region, these two measurements from multiple trees can be used to reconstruct summer temperature (δ13C) and summer precipitation (δ18O) with sufficient independence to allow the evolution of these climate parameters to be reconstructed with high levels of confidence.

How should a forest carbon rent policy be implemented?

Forest economics literature commonly uses two alternative ways to apply carbon payments to forest owners: a carbon rental policy and a policy where carbon compensations are based on subsidies and taxes. Conditions under which these two policy schemes lead to similar market outcomes are identified: We show that perfect capital markets and rational expectations over carbon prices are required for the equivalency of the two policy schemes.
