Climate regulation of fire emissions and deforestation in equatorial Asia por Werf, G.R. van der, Dempewolf, Jan, Trigg, S.N., Randerson, J.T., Kasibhatla, P.S., Giglio, L., Murdiyarso, Daniel, Peters, W., Morton, D.C., Collatz, G.J., Dolman, A.J., DeFries, Ruth S.

“…We found that average fire emissions from this region [128 ± 51 (1σ) Tg carbon (C) year −1 , T = 10 12 ] were comparable to fossil fuel emissions. In Borneo, carbon emissions from fires were highly variable, fluxes during the moderate 2006 El Niño more than 30 times greater than those during the 2000 La Niña (and with a 2000–2006 mean of 74 ± 33 Tg C yr −1 ). …”

From lignocellulosic metagenomes to lignocellulolytic genes : trends, challenges and future prospects por Batista-García, Ramón Alberto, Sanchez-Carbente, María del Rayo, Talia, Paola Mónica, Jackson, Stephen A., O'Leary, Niall D., Dobson, Alan D. W., Folch-Mallol, Jorge Luis

“…Lignocellulose is the most abundant biomass on Earth with immense potential to act as a primary resource for the production of a range of compounds currently obtained from fossil fuel sources. However, lignocellulosic feedstocks remain largely underexploited due to the complex mixture of recalcitrant polymers present, whose structural features hinder access to the utilizable monosaccharide reservoir within cellulose. …”

pBAR–H3.2, a native-optimized binary vector to bypass transgene silencing in alfalfa por Pascuan, Cecilia Gabriela, Bottero, Ana Emilia, Kapros, Tamas, Ayub, Nicolás Daniel, Soto, Gabriela Cynthia

“…Besides, due to its ability to grow without nitrogen fertilizers derived from fossil fuels and conditions of long-duration perennial crop, alfalfa is a natural candidate for large production of renewable raw materials and vaccines at extremely low cost (Aguirreburualde et al. 2013; Saruul et al. 2002). …”

Just Transition - COP29 Negotiation Updates por Koren, Judith, Rabago, Laura

“…Originating from labor movements in North America in the 1970s, it has developed as a central piece in the energy transition, highlighting the need for fair job creation, worker protections, reskilling, and social dialogue, particularly in sectors heavily impacted by decarbonization, such as coal and other fossil fuels. First recognized in international climate negotiations and agreements through the COP21 Paris Agreement, the just transition has made notable progress as a key action item for the proceeding COPs. …”

Implementing REDD+ (Reducing Emissions from Deforestation and Degradation): evidence on governance, evaluation and impacts from the REDD-ALERT project por Matthews RB, Noordwijk, Meine van, Lambin, E.F., Meyfroidt, Patrick, Gupta J, Verchot, Louis V., Hergoualc'h, Kristell, Veldkamp, E.

“…There are indications that there is only a short and relatively small window of opportunity of making REDD+ work—these included the fact that forest-related emissions as a fraction of total global GHG emissions have been decreasing over time due to the increase in fossil fuel emissions, and that the cost efficiency of REDD+ may be much less than originally thought due to the need to factor in safeguard costs, transaction costs and monitoring costs. …”
