The carbon cycle of tropical terrestrial vegetation plays a vital role in the storage and exchange of atmospheric CO2. But large uncertainties surround the impacts of land-use change emissions, climate warming, the frequency of droughts, and CO2 fertilization. This culminates in poorly quantified carbon stocks and carbon fluxes even for the major e...
The World Organisation for Animal Health advocates the zoning approach for the surveillance and monitoring of foot and mouth disease (FMD), a highly contagious animal disease. Our purpose is to implement the zoning approach in Tunisia by identifying existing natural and artificial barriers to the movement of live animals. A Geographic Information S...
Purpose: This article explores to what extent a Delphi consensus study can help in designing a framework for assessing agricultural innovation systems (AIS), and this in a perspective of transformation of these systems in a diversity of countries. Approach: First, we reviewed the diversity of existing assessment methodologies in terms of their asse...
Background: Little is known about volunteers from Northern research settings who participate in vaccine trials of highly infectious diseases with no approved treatments. This article explores the motivations of HIV immunocompromised study participants in Canada who volunteered in a Phase II clinical trial that evaluated the safety and immunogenicit...
Over the past two decades spaceborne LiDAR systems have gained momentum in the remote sensing community with their ability to accurately estimate canopy heights and aboveground biomass. This article aims at using the most recent global ecosystem dynamics investigation (GEDI) LiDAR system data to estimate the stand-scale dominant heights ( Hdom ), a...
This article presents a participative and iterative qualitative risk assessment framework that can be used to evaluate the spatial variation of the risk of infectious animal disease introduction and spread on a national scale. The framework was developed though regional training‐action workshops and field activities. The active involvement of natio...
In sustainability science, interdisciplinarity, i.e., the integration of perspectives from different disciplines, is built collectively from interactions among researchers of various disciplines (“collective interdisciplinarity”) but also results from the fact that researchers have backgrounds in multiple disciplines (“individual interdisciplinarit...
Background: Interest in impact evaluation has grown rapidly as research funders increasingly demand evidence that their investments lead to public benefits. Aims: This paper analyses literature to provide a new definition of research impact and impact evaluation, develops a typology of research impact evaluation designs, and proposes a methodologic...
Full waveform (FW) LiDAR systems have proven their effectiveness to map forest biophysical variables in the last two decades, owing to their ability of measuring, with high accuracy, forest vertical structures. The Global Ecosystem Dynamics Investigation (GEDI) system on board the International Space Station (ISS) is the latest FW spaceborne LiDAR ...
Background: Crop pests are among the greatest threats to food security, generating broad economic, social, and environmental impacts. The impacts of crop pests can be reduced by identifying the conditions that generate them early. These pests interact with their hosts and the environment through complex pathways, and it is increasingly common to fi...
