Carbon footprint of the colombian cocoa production REA
Ortiz-Rodríguez,Oscar O.; Villamizar-Gallardo,Raquel A.; Naranjo-Merino,Carlos A.; García-Caceres,Rafael G.; Castañeda-galvís,María T..
ABSTRACT Cocoa is an important commercial crop in the tropics; and estimating the carbon emissions in the producing-areas is a worthwhile effort. The main goal of the current paper was to evaluate the carbon footprint (CF) per kilogram of Colombian cocoa bean produced under conventional and agroforestry managements, following the methods proposed by PAS 2050. In this research, we compared our results to other worldwide researches, showing an overview of the current limitations and challenges involving the CF researches. Our results showed that all calculated environmental burdens were lower for the conventional management. In the agroforestry practice, composting of cocoa pod husks contributed with approximately 34.00E+00 g methane and 2.55E+00 g nitrous...

Environmental performance of farmer-level corn production systems in the Philippines CIGR Journal
Flores, Edgar Dulay; Dela Cruz, Renita S. M.; Antolin, Ma Cecilia R..
Four corn production systems at farmer-level of operation were evaluated. Environmental performance such as energy use, energy efficiency, greenhouse gas emission (GHG) and carbon efficiency were determined. Data were collected from 60 corn producing farmers using survey questionnaires and face to face interview. The input energy to produce an output energy of 69,714.06 and 73,029.60 MJ/ha for sun drying and mechanical drying, respectively, were 22,346.27, 31, 469.75, 22, 399.05 and 31,522.53 MJ/ha for systems 1 (manual harvesting and sun drying), 2 (manual harvesting and mechanical drying), 3 (mechanical harvesting and sun drying) and 4 (mechanical harvesting and mechanical drying), respectively.  The highest energy input was observed for system 4...

Greenhouse gas emissions on the treatment of swine slurry by composting. Repositório Alice
OLIVEIRA, P. A. V. de; ANGNES, G.; NICOLOSO, R. da S.; HIGARASHI, M. M..
The treatment of swine manure through composting is seen as an alternative to minimize environmental impact and im prove nutrient recycling. However, the degradation of organic matter during the composting process promotes greenhouse gas emissions (GHG: CO2, CH4, N2O), NH3 and water vapor. The objective of this study was to measure the flux of these gases to perform the mass balance (DM, TN, C and P) of composting piles. Three compost piles (3 m3, initial mass .935 kg of sawdust and slurry) were mounted inside PVC tunnels with controlled ventilation (flow 1.526 m3 /h). We evaluated temperatures and humidity (Datalogger TESTO 174H) inside and outside the tunnels and inside the biomass (TESTO Mod. 926, Type T), performed physical-chemical analysis of compost...

Life cycle assessment as a tool to evaluate the impact of reducing crude protein in pig diets Ciência Rural
Monteiro,Alessandra Nardina Trícia Rigo; Dourmad,Jean-Yves; Pozza,Paulo Cesar.
ABSTRACT: Environmental impacts of livestock systems, especially pig production, have come under increasing debate in recent years. The challenge is in meeting the growing demand for food at an affordable cost, without compromising environmental integrity. Previous studies have shown that feed production is responsible for the majority of CO2-eq. emission resulting from pig farming systems. This seems to indicate that feed strategies could be an effective tool to achieve the sustainability of the pork chain. Therefore, dietary crude protein reduction, through the addition of industrial amino acids, lessens the nitrogen excretion by pigs and, consequently, could mitigate the effects on the environment of pig production. In this sense, to effectively...

Mechanised shea butter production in south-western Nigeria using Life Cycle Assessments (LCA) approach from gate-to-gate CIGR Journal
EWEMOJE, Temitayo Abayomi; Oluwaniyi, Oluwamayowa Oluwafemi.
Agriculture and food processing, industry are among the largest industrial sectors that uses large amount of energy. Thus, a larger amount of gases from their fuel combustion technologies are being released into the environment. The study was therefore designed to assess each unit production processes in order to identify hotspots using life cycle assessments (LCA) approach in South-western Nigeria. Data such as machine power rating, operations duration, inputs and outputs of shea butter materials for unit processes obtained at site were used to modelled Life Cycle Impact Analysis (LCIA) on GaBi6 (Holistic Balancing) software.  Four scenarios were drawn for the impact assessments. Material sourcing from Kaiama, Scenarios 1, 3 and Minna Scenarios 2, 4 but...

ความเป็นไปได้ของการใช้สารปรับปรุงดินเพื่อลดก๊าซเรือนกระจกและขณะเดียวกันรักษาผลผลิตข้าว: รายงานการวิจัยฉบับสมบูรณ์ Thai Agricultural
Patcharee Saenjan; Daungsamorn Tulapithak; Kasuyuki Inbuchi.
Field experiment was conducted in farmer’s rice field with loamy soil in Khon Kaen province, northeast of Thailand during to study the effect of different levels of sulfate (SO42-) on methane emission and rice yield. SO42- was applied at the rate of 0, 50, 100, and 210 kg SO42- ha-1 by using ammonium phosphate (42% SO42-) with balanced amount of 80 kg N, 100 kg P2O5 and 80 kg K2O ha-1 by adding various fertilizers. The experiment was laid out in randomized completely block design (RCBD) with tripled replication. CH4 flux was measured every week by using closed chambers method. Global warming potential (GWP) was also calculated. Soil samples were collage at each growth stage to determine SO42-, NH4+ and Fe2+. Rice yield was measured at harvest. The...
