Carbon footprint of yerba mate (Ilex paraguariensis) value chain in Misiones Province (Argentina) por Chifarelli, Diego Hernan, Gruber, Lorena, Azzini, Lapo, Nicese, Francesco Paolo, Giordani, Edgardo

“…This study aimed at assessing the environmental impact, namely of CO2 equivalent (CO2eq.) emissions, of the YM value chain while identifying environmental hotspots along the production chain, from nursery up to transport. …”

Aeolian Remobilisation of Volcanic Ash: Outcomes of a Workshop in the Argentinian Patagonia por Jarvis, Paul Antony, Bonadonna, Constanza, Dominguez, Lucía, Forte, Pablo, Frischknecht, Corine, Bran, Donaldo Eduardo, Aguilar, Rigoberto, Beckett, Frances, Elissondo, Manuela, Gillies, John, Kueppers, Ulrich, Merrison, Jonathan, Varley, Nick, Wallace, Kristi L.

“…Furthermore, since forecast models currently rely on poorly-constrained dust emission schemes, we call for laboratory and field measurements to better parameterise the flux of volcanic ash as a function of friction velocity.While source area location and extent are currently the primary inputs for dispersion models, once emission schemes become more sophisticated and better constrained, other parameters will also become important (e.g., source material volume and properties, effective precipitation, type and distribution of vegetation cover, friction velocity). …”

Community forestry in Cameroon: opportunity or constraint for REDD+? por Bele, M.Y., Sonwa, D.J., Tiani, A.M.

“…Community forestry governance arrangements were not designed with the objective of achieving verifiable emissions reductions or carbon stock values. Hence, existing community forestry institutions may not address all the specific demands of REDD+ programs. …”

Active and passive chlorophyll fluorescence measurements at canopy level on potato crops. Evidence of similitude of diurnal cycles of apparent fluorescence yields por Loayza, H., Moya, I., Quiróz, R., Ounis, A., Goulas, Y.

“…Under high irradiance associated with clear sky we observed an increase of the F760/F687 ratio, which we attributed to the contributions in the 760 nm emission of photosystem I fluorescence from deeper layers of the leaves, on one end, and by the decrease of 687 nm emission as a result of red fluorescence re-absorption, on the other end. …”

Major carbon losses from degradation of Mauritia flexuosa peat swamp forests in western Amazonia por Hergoualc'h, Kristell, van Lent, J., Dezzeo, N., Verchot, L.V., van Groenigen, J.W., López Gonzales, M., Grandez-Rios, J.

“…While this can transform these C sinks into significant sources, the magnitude of C fluxes in natural and disturbed conditions remains unknown. Here, we estimated emissions from degradation along a gradient comprising undegraded (Intact), moderately degraded (mDeg) and heavily degraded (hDeg) palm swamps. …”
