Ground Zero? Let’s get real on regeneration! Report: Assessing greenhouse gas emissions from post-harvest residue management in coffee and cocoa production systems por Lourenço, Késia Silva, Barthel, Matti, Velthof, Gerard, Westerik, Dorien, Rahn, Eric, Pulleman, Mirjam, Six, Johan, Giller, Ken E

“…Improper handling of these residues can lead to a range of environmental challenges, including water pollution and eutrophication, K leaching, and the release of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). C footprint calculations (expressed as CO2-C emission rates per kg of product produced) require the inclusion of the emissions from all activities inside the farm (on-farm), including those upstream related to the manufacture of farm inputs (off-farm) such as fertilizer and transport of materials to the farm, as well as post-harvest processes down the value chain. …”

Effect of botanically diverse pastures on the milk fatty acid profiles in New Zealand dairy cows por Ström, Gunilla

“…Botanically diverse pastures are commonly used in New Zealand to reduce the ruminant environmental impact by reducing the methane production from the rumen digestion. In order to evaluate the effects diverse pasture species have on the milk fatty acid profile seventy-two lactating Friesian-Jersey crossbred dairy cows were used in a randomised block design with two replicates of six treatments. …”

Climate impact of bioH2 production from biogas using CO2 mineralization for carbon capture and storage por Harðardóttir, Hera

“…This study used a hypothetical biogas plant where the bioH2 is produced with biomethane as feedstock via the steam methane reforming (SMR) method. The hypothetical carbon mineralization storage site is located right outside of Uppsala where the CO2 emissions are injected and long-term stored each day. …”

Sustainable and Low Greenhouse Gas Emitting Rice Production in Latin America and the Caribbean : A Review on the Transition from Ideality to Reality por Chirinda, Ngonidzashe, Arenas, Laura, Katto, María, Loaiza, Sandra, Correa, Fernando, Isthitani, Manabu, Loboguerrero, Ana María, Martínez-Barón, Deissy, Graterol, Eduardo, Jaramillo, Santiago, Torres, Carlos Felipe, Arango, Miguel, Guzmán, Myriam, Avila, Ivan, Hube, Sara, Kurtz, Ditmar Bernardo, Zorrilla, Gonzalo, Terra, Jose, Irisarri, Pilar, Tarlera, Silvana, LaHue, Gabriel, Scivittaro, Walkyria Bueno, Noguera, Aldo, Bayer, Cimelio

“…However, since rice production is associated with increases in the atmospheric concentration of two greenhouse gases (GHGs), namely methane (CH4) and nitrous oxide (N2O), the challenge is on ensuring that production increases are not associated with an increase in GHG emissions and thus do not cause an increase in GHG emission intensities. …”
