El objetivo del estudio fue la caracterización productiva y de emisiones modeladas gases efecto invernadero (GEI) en 61 sistemas lecheros localizados cinco regiones Honduras. Durante las fases inicial (FI) final (FF), con encuestas aplicadas individualmente a los productores, se identificaron aspectos técnicos productividad. Variables numéricas expresadas Microsoft Excel® permitieron, el modelo...

Production of pork, the most consumed meat globally, is estimated to emit 668 m tonnes CO2-eq of greenhouse gases each year. Amongst various production systems that comprise the pig industry, grain-based intensive production is widely regarded as the largest polluter of the environment, and thus it is imperative to develop alternative systems that can provide the right balance between sustainab...

This study assesses the biomethane (CH4) generation and greenhouse gas (GHG) emissions resulting from municipal solid waste landfilling in Phnom Penh, Cambodia, with a focus on impact of fugitive CH4 operation processes four scenarios: simple dumping (S1), improved management leachate treatment (S2), engineered landfill flaring (S3), energy recovery (S4). The also considered environmental benef...

This paper presents an application of LCA (Life Cycle Assessment) with a view to analyzing the environment aspects of rice straw-based power generation in Malaysia. It also compares rice straw-based power generation with that of coal and natural gas. GHG (Greenhouse gas) emission savings were calculated. It finds that rice straw power generation can save GHG (greenhouse gas) emissions of about ...

Energy use and greenhouse gases (GHG) emissions in rainfed canola production in north eastern Iran were analyzed to find measures to reduce energy use and GHG emissions. Four production scenarios, i.e. a high-input, a low-input, a better crop management and a usual scenario, evaluated. All activities and production processes were monitored and recorded over three consecutive years. The usua...

Tomato production under tunnel structures has shown promising returns in recent years Pakistan. However, the energy use and GHGs dynamics remain largely unknown for tomato controlled conditions. This study estimates budgeting GHG emission off-season (tunnel-farming) production. Study data were gathered from 70 growers through a simple random sampling technique. Energy efficiency, productivity, ...

In this study, 54 five-year-old farmed female beluga at stage II of sexual maturation were treated with 0 (control), 0.2, 0.4, 0.8 and 1.6 g of dietary soy equol (EQ) and genistein (GE) per each kilogram (kg) of diet during a year. Blood samples were collected and ovarian biopsy was performed quarterly. Results showed that 64.4% of the Huso huso sexually matured at EQ 0.4 g/kg and reached stage...

This work analyzes the environmental impacts of milk production in an intensive dairy farm situated in the Northern Italy region of the Po Valley. Three manure management scenarios are compared: in Scenario 1 the animal slurry is stored in an open tank and then used as fertilizer. In scenario 2 the manure is processed in an anaerobic digestion plant and the biogas produced is combusted in an in...
