“…The potential impact of any genetically modified crop on the environment is a key issue (Bennett et al ., 2004, 2006a,b). Increasing concern about climate change (for instance, see Stern Review, 2006) means that the potential for genetically modified crops to cut greenhouse gas emissions requires more detailed analysis.…”

SummaryAgriculture, particularly intensive crop production, makes a significant contribution to environmental pollution. A variety of canola ( Brassica napus ) has been genetically modified to enhance nitrogen use efficiency, effectively reducing the amount of fertilizer required for crop production. A partial life-cycle assessment adapted to crop production was used to assess the potential environmental impacts of growing genetically modified, nitrogen use-efficient (GMNUE) canola in North Dakota and Minnesota compared with a conventionally bred control variety. The analysis took into account the entire production system used to produce 1 tonne of canola. This comprised raw material extraction, processing and transportation, as well as all agricultural field operations. All emissions associated with the production of 1 tonne of canola were listed, aggregated and weighted in order to calculate the level of environmental impact. The findings show that there are a range of potential environmental benefits associated with growing GMNUE canola. These include reduced impacts on global warming, freshwater ecotoxicity, eutrophication and acidification. Given the large areas of canola grown in North America and, in particular, Canada, as well as the wide acceptance of genetically modified varieties in this area, there is the potential for GMNUE canola to reduce pollution from agriculture, with the largest reductions predicted to be in greenhouse gases and diffuse water pollution.

“…Based on these criteria we included 16 LCA studies (Table 1), and excluded 9 LCA studies (Baumgartner et al, 2008;Ogino et al, 2004;Eriksson et al, 2005;Bennett et al, 2006;Dalgaard et al, 2006;Elferink and Nonhebel, 2007;Ellingsen and Aanondsen, 2006;Pelletier, 2008;Weidema et al, 2008).

“…Another important factor evaluated in some studies was the impact of innovative practices during the cultivation or processing of feed ingredients. The use of maize genetically modified (59), different processing methods for soybean (48), or crop-animal integrated systems (41) were evaluated, and impacts in the final product (i.e., functional unit) were reported.…”

Environmental Impacts of Pig and Poultry Production: Insights From a Systematic Review

et al. 2021

Pig and poultry production systems have reached high-performance levels over the last few decades. However, there is still room for improvement when it comes to their environmental sustainability. This issue is even more relevant due to the growing demand for food demand since this surplus food production needs to be met at an affordable cost with minimum impact on the environment. This study presents a systematic review of peer-reviewed manuscripts that investigated the environmental impacts associated with pig and poultry production. For this purpose, independent reviews were performed and two databases were constructed, one for each production system. Previous studies published in peer-reviewed journals were considered for the databases if the method of life cycle assessment (LCA) was applied to pig (pork meat) or poultry (broiler meat or table eggs) production to estimate at least the potential effects of climate change, measured as CO2-eq. Studies considering the cradle-to-farm gate were considered, as well as those evaluating processes up to the slaughterhouse or processor gate. The pig database comprised 55 studies, while 30 publications were selected for the poultry database. These studies confirmed feeding (which includes the crop cultivation phase, manufacturing processes, and transportation) as the main contributor to the environmental impact associated with pig and poultry production systems. Several studies evaluated feeding strategies, which were indicated as viable alternatives to mitigate the environmental footprint associated with both production chains. In this study, precision feeding techniques are highlighted given their applicability to modern pig and poultry farming. These novel feeding strategies are good examples of innovative strategies needed to break paradigms, improve resource-use efficiency, and effectively move the current productive scenario toward more sustainable livestock systems.
