  Grant type: BPD

Summary

I am a physical geographer and soil scientist, currently working as a research scientist (fellow) at CESAM - Centre for Environmental and Marine Studies - of the University of Aveiro, Portugal. My fellowship was awarded by the national Science and Technology Foundation (FCT) and focuses on soil hydrology and erosion after biochar application to soils.

My primary research interest is the interaction between vegetation and its abiotic environment, particularly vegetation - soil organic matter (SOM) - soil hydrology dynamics. In practical terms this often relates to researching the interaction between climate or land use change and dynamics of SOM, soil erosion and desertification.

MISSION STATEMENT
"It is my firm belief that to deal successfully with the challenges posed by climate and land use change on the one hand, and food security and environmental functioning on the other, researchers are needed with both broad and deep skills. I have attempted to achieve this through my education and research experience and hope to apply and extend my skills to understand the planet better and help keep it viable and functioning."

Selected Highlights

  • I received the 2017 Research Day award from the University of Aveiro "in recognition of the significance and quality of the research developed at the UA".

  • I was the senior researcher on a major meta-analytical review that showed biochar to boost crop yield in the tropics but not in the temperate zone

  • I was awarded Researcher of the Month for April 2016 at the University of Aveiro. Read the accompanying interview here.

  • With my co-authors, I contributed to the discourse on soil policy with a correspondence in Nature magazine.

  • With my co-authors, I published a book chapter in the 2nd edition of 'Biochar for Environmental Management', edited by Johannes Lehmann & Stephen Joseph. The chapter is titled 'Biochar Sustainability and Certification' and outlines a concept of how sustainable biochar would need to be certified both from the production perspective as well as the environmental application perspective.

  • I visited the Volcani Center (Israel) on a Short Term Scientific Mission (COST-STSM-TD1107-13644) in January-February 2014 to work with Meni Ben-Hur and Ellen Graber on the effect of biochar on soil erosion, using a perforated-tray rotating disc type rainfall simulator.

  • I published a review on tolerable soil erosion in EARTH-SCIENCE REVIEWS. With my co-authors we reviewed the definitions of 'tolerable soil erosion' and extensively reviewed the literature to derive soil formation rates, including dust deposition (to an extent), as a basis for defining tolerable soil erosion rates in Europe.

Networks & Committees

October 2017:
I joined the International Biochar Initiative's new and independent Scientific Committee whose mission is to "critically assess and synthesize the scientific literature regarding the interactions between biochar and soils, the wider environment, and human health, and to provide an interface between science and the general public where the science is explained in a transparent and balanced way using broadly accessible language". The Science Committee is made up of 16 scientists from across the world.

March 2012:
COST Action TD1107 ‘Biochar as option for sustainable resource management’. I was the national representative of Portugal for this COST Action, which connected scattered European Biochar research to enable quick implementation of intelligent material flow management systems, to maintain or improve soil quality while efficiently sequestering carbon in the long-term. The Action aimed at coordinating European Biochar research, bringing together researchers, stakeholders and potential users from EU and candidate countries.
I was the leader of WG2 'Land Use Management', which compared Biochar's effects along Trans-European climatic gradients based on meta data.

August 2012:
Launch of the Biochar Investigation Network of Portugal (BINP). The mission of BINP is to bring together people involved in biochar research and production in Portugal, to facilitate collaborations by providing a platform for networking, to disseminate national and international biochar news, funding opportunities, conferences and workshops.

Organisation of scientific meetings

In June 2014, together with Ana Catarina Bastos, I organised a 2-day, joined WG2 & WG4 meeting for the COST Action TD1107 (Biochar as option for sustainable resource management), titled 'Biochar: on the path to the required level of scientific understanding'. Forty scientists participated in thematic groups. The outcome is published in a special issue.

convened a symposium at EUROSOIL2012 titled 'Effects of Biochar on Soil Properties, Processes and Functions' (S5.3). Here we brought together leading scientists from across the world to present their latest results. A total of 85 oral and poster presentations were made, constituting the third largest session at the conference after the classical sessions on soil erosion and soil organic matter.
I organised an EU side-event on biochar at the COP15 in Copenhagen, Denmark. It was a well-attended event, chaired by Luca Montanarella (JRC) with presentations by Johannes Lehmann (Cornell University), Saran Sohi (University of Edinburgh), and me. I presented on biochar effects on soils, including important knowledge gaps (see presentation here), and published a major JRC (European Commission) report on biochar.
