PurposeIn the “Cerrado” (Brazilian savanna), sunflower comes mostly from a cropping system where its seeding follows soybean harvest. Soybean has a much higher economic value, but this association with sunflower reduces the environmental impacts from both crops by sharing resources. This study performed a life-cycle assessment (LCA) of the soybean-sunflower cropping system, identified its hotspots, and compared its environmental performance with two hypothetical monocultures, in order to… 
Comparative Farm-Gate Life Cycle Assessment of Oilseed Feedstocks in the Northern Great Plains
Second generation biofuel feedstocks such as carinata (Brassica carinata L. Braun) and camelina (Camelina sativa L. Crantz) offer unique advantages over traditional bioenergy alternatives, such as
Main aspects of sunflower production in Brazil
The success of establishing the sunflower is associated with the adequate management of soil fertility, use of cultivars adapted to different environments, plant arrangement, seed quality and adequate phytosanitary management, among other factors.
LCA of Soybean Supply Chain Produced in the State of Pará, Located in the Brazilian Amazon Biome
Recently, Brazil became the biggest soybean producer and exporter in the world. The state of Pará, located in the Brazilian amazon biome, became one of the last agricultural frontiers of the country,
This is anOp Abstract – Sunflower is one of the most important oilseed crops in the world, since its grains have high oil content (38% to 50%), primarily used for the production of high quality oil.
Environmental Impact Assessment of Agricultural Production Using LCA: A Review
Life cycle impact assessment (LCA) provides a better understanding of the energy, water, and material input and evaluates any production system’s output impacts. LCA has been carried out on various
Environmental and Energy Performance of Ethanol Production from the Integration of Sugarcane, Corn, and Grain Sorghum in a Multipurpose Plant
Although in the last 40 years only sugarcane has been harnessed for the production of ethanol in Brazil, corn production has grown strongly in certain areas, and may serve as a supplementary
The availability of life-cycle assessment, water footprinting, and carbon footprinting studies in Brazil
PurposeThis study aimed to determine the availability of environmental life cycle assessment (LCA), water footprinting, and carbon footprinting data in Brazil. In particular, the study is targeted at


Designing sustainable crop rotations using Life Cycle Assessment of crop combinations
The introduction of grain legumes in crop rotations offers the potential to reduce the environmental impact of European agriculture. The main advantage is the independence of nitrogen fertilisers due
Decoupling of deforestation and soy production in the southern Amazon during the late 2000s
Evidence is provided that reduced deforestation and increased agricultural production can occur simultaneously in tropical forest frontiers, provided that land is available and policies promote the efficient use of already-cleared lands (intensification) while restricting deforestation.
Challenges in assessing the environmental impacts of crop production and horticulture.
This chapter discusses the main challenges of the LCA procedure and gives guidance on how to consider the multifunctionality of agricultural production and how to draw the boundaries of the production system.
