biodiversity – the variety of plant and animal life in the world or in a habitat, a high level of which is usually considered to be important and desirable.

Bioeconomy – Bioeconomy is Europe’s response to key environmental challenges the world is facing already today.

As such, the model can provide scientists and policymakers with the means to assess, on a global basis, the rational production of food, forest fiber, and bioenergy, all of which contribute to human welfare.

ground-based sampling data – Remote sensing investigations often involve sampling on the ground to estimate the mean of some property within ground resolution elements. Investigators have used classical statistics to determine the size of sample required to produce a desired precision. However, classical statistics is based on assumptions that do not hold when the target population is spatially dependent. Remotely sensed data and ground cover are usually spatially correlated, and in these circumstances the size of sample required will be less when sampling is done on a regular grid. This is demonstrated for several variables measured at the ground.

ISIB-04a-2014 – this was the H2020 identifier for the topic “Improved forest data” which funded the DIABOLO project. A sister project “ALTERFOR” was funded from topic ISIB-04b-2015 “Improved forest management models”. 

Harmonisation – in NFIs is the process of making data and estimates comparable across administrative borders. Common reference definitions must be agreed in the countries involved in the harmonisation process. Of relevance:

harmonised forest data – harmonisation procedures are agreed by the participant countries. These included the establishment of a common nomenclature for forest tree species among participant countries for the most common trees and the establishment of standardised procedures for the provision of data. 

harmonised information – harmonisation of information is the process of bringing together  data of different file formats, naming conventions, and columns, and transforming it into one cohesive data set.

Research Impact – the definition of research impact really depends on what you might do with the results of research. As a researcher, impact may be a contribution that research makes to our understanding of a subject, advances to methods, to theories and the application of results. But research impact can also make a contribution to society and the economy. It is important that we are able to demonstrate the impact.

Land Use Land Use Change and Forestry (LULUCF) – The rate of build-up of CO2 in the atmosphere can be reduced by taking advantage of the fact that atmospheric CO2 can accumulate as carbon in vegetation and soils in terrestrial ecosystems. Under the United Nations Framework Convention on Climate Change any process, activity or mechanism which removes a greenhouse gas from the atmosphere is referred to as a “sink”. Human activities impact terrestrial sinks, through land use, land-use change and forestry (LULUCF) activities, consequently, the exchange of CO2 (carbon cycle) between the terrestrial biosphere system and the atmosphere is altered.–land-use-change-and-forestry-lulucf

LULUCF reporting – Under EU legislation adopted in May 2018, EU Member States have to ensure that greenhouse gas emissions from land use, land use change or forestry are offset by at least an equivalent removal of CO₂ from the atmosphere in the period 2021 to 2030. The Regulation sets a binding commitment for each Member State to ensure that accounted emissions from land use are entirely compensated by an equivalent removal of CO₂ from the atmosphere through action in the sector. This is known as the “no debit” rule.

SAR based monitoring – Synthetic Aperture Radar (SAR). This involves using microwaves. A radar altimeter sends out pulses of microwave signals and record the signal scattered back from the earth surface. The height of the surface can be measured from the time delay of the return signals. In synthetic aperture radar (SAR) imaging, microwave pulses are transmitted by an antenna towards the earth surface. The microwave energy scattered back to the spacecraft is measured. The SAR makes use of the radar principle to form an image by utilising the time delay of the backscattered signals. Due to the cloud penetrating property of microwave, SAR is able to acquire “cloud-free” images in all weather. This is especially useful in the tropical regions which are frequently under cloud covers throughout the year. Being an active remote sensing device, it is also capable of night-time operation.
