<p>Climate change is a global issue requiring unified action. Methane gas is a major component of greenhouse gas emissions contributing to global warming. This project is exploring the commercial potential of Pastoral Greenhouse Gas Research Consortium (PGgRc) developed technologies designed to mitigate the largest source of agricultural methane emissions. These technologies are methane vaccines and inhibitors targeting emissions from enteric fermentation in ruminant livestock. The two technologies share functional aspects but require different administration and upkeep.  As novel technologies designed for a developing market the commercial potential of PGgRc’s methane vaccines and inhibitors is uncertain. To validate the potential methane mitigation products this project focuses on farmer adoption and interaction with the technologies. Interviews with farmers around New Zealand have been used to identify the strengths and weaknesses of methane vaccines and inhibitors from the perspective of the end user.  A thematic analysis of the transcribed data highlighted various concerns among the participating farmers and provides a map of areas needing further investigation when moving forward with developing the technologies. Of key importance was the value methane vaccines and inhibitors offered the participants. Currently, methane mitigation offers no financial benefits to participants and good feelings about acting against climate change are not substantial enough to mitigate purchase and administration costs.  There is potential that using PGgRc’s methane vaccines and inhibitors could improve livestock productivity, but it is yet to be verified based on current testing and development. Establishing that using the technologies leads to increased live weight gain or milk and wool production could provide profitability benefits that farmers would value. This hinges on any benefits providing substantial enough gains to the farmer to offset the purchase and administration costs.  If no productivity benefits are identified government regulations creating a methane cost or subsidising the technologies could be necessary for methane vaccines and inhibitors to have value within the agricultural sector. Alternatively, if consumer purchasing behaviour shifts in favour of low emissions products the agricultural sector will need to shift production methods to remain competitive in the new market environment.  PGgRc aims to employ a licensing business model using the methane vaccine and inhibitor IP they possess.

Greenhouse gases are becoming devastating on agriculture and environment because of its effect on climate and global warming. The aim of this review is to provide update on livestock greenhouse gases emission and rekindle available mitigation strategies. Recently, global warming and climate change have become one of the most discussed issues globally because of their negative effect on ecosystem worldwide. The livestock sub-sector as a major source of greenhouse gas emission, has been identified to contribute substantially to the recent rise in global warming and climate change. Livestock, most importantly ruminants plays a major role in the emission of methane, one of the potent greenhouse gases. This methane is usually released through enteric fermentation in animals and manure management system, though the latter account for smaller quantity. Estimate of methane emission inventory from livestock in Nigeria showed that 96.15 % of methane produced by livestock was by ruminants with cattle alone accounting for 74.06 %. With this background, strategies to date for reducing methane emissions should centre on ruminant. Efforts to reduce methane emissions from enteric fermentation generally focus on options for improving production efficiency. This has been demonstrated with intensive animal production systems. However, in Nigeria, this system has been successful only for non-ruminants while the extensive and semi extensive systems are being practiced for ruminants. In view of this, options for reducing emissions must be selected to be consistent with country-specific circumstances. Those circumstances should include animal management practices (including cultural traditions), nutrition and economic development priorities.     Les gaz à effet de serre deviennent dévastateurs de l'agriculture et de l'environnement en raison de son effet sur le climat et le réchauffement de la planète. L'objectif de cet examen est de fournir une mise à jour sur les stratégies d'atténuation disponibles des gaz à effet de serre de bétail. Récemment, le réchauffement climatique et le changement climatique sont devenus l'une des questions les plus discutées à l'échelle mondiale en raison de leur effet négatif sur l'écosystème mondial. Le sous-secteur de l'élevage en tant que source majeure d'émissions de gaz à effet de serre, a été identifié pour contribuer de manière substantielle à la hausse récente du réchauffement de la planète et du changement climatique. Le bétail, plus important encore, les ruminants jouent un rôle majeur dans l'émission de méthane, l'un des gaz à effet de serre puissants. Ce méthane est généralement libéré par la fermentation entérique chez les animaux et le système de gestion de fumier, bien que ces derniers représentent une plus petite quantité. L'estimation des stocks d'émissions de méthane provenant du bétail au Nigéria a montré que 96,15% de méthane produites par le bétail étaient par des ruminants avec des bovins à eux-mêmes représentant 74,06%. Avec ce contexte, des stratégies à ce jour pour réduire les émissions de méthane doivent être centrées sur le ruminant. Les efforts visant à réduire les émissions de méthane de la fermentation entérique se concentrent généralement sur les options d'amélioration de l'efficacité de la production. Cela a été démontré avec des systèmes de production d'animaux intensifs. Cependant, au Nigéria, ce système n'a abouti que pour les non-ruminants tandis que les systèmes étendus et semi-étendus sont pratiqués pour les ruminants. Compte tenu de cela, les options de réduction des émissions doivent être sélectionnées pour être cohérentes avec des circonstances spécifiques à chaque pays. Ces circonstances devraient inclure des pratiques de gestion des animaux (y compris des traditions culturelles), des priorités de nutrition et de développement économique

The Czech Republic

As a part of its obligations under the Climate Convention, the Czech Republic must annually estimate and report its anthropogenic emissions of greenhouse gases. This also applies for the sector of agriculture, which is one of the greatest producers of methane and nitrous oxide emissions. This paper presents the approaches applied to estimate emissions in agricultural sector during the period 1990–2006. It describes the origin and sources of emissions, applied methodology, parameters and emission estimates for the sector of agriculture in the country. The total greenhouse gas emissions reached 7644 Gg CO<sub>2</sub> eq. in 2006. About 59% (4479 Gg CO<sub>2</sub> eq.) of these emissions has originated from agricultural soils. This quantity ranks agriculture as the third largest sector in the Czech Republic representing 5.3% of the total greenhouse gas emissions (GHG). The emissions under the Czech conditions consist mainly of emissions from enteric fermentation, manure management and agricultural soils. During the period 1990–2006, GHG emissions from agriculture decreased by 50%, which was linked to reduced cattle population and amount of applied fertilizers. The study concludes that the GHG emissions in the sector of agriculture remain significant and their proper assessment is required for sound climate change adaptation and mitigation policies.

Agriculture in the context of climate change is often a provocative subject because agriculture is both heavily impacted by the warming world and also a principal contributor to climate change. As efforts to reduce greenhouse gas emissions increase, the EU is pushing all sectors to integrate measures to combat climate change. This article argues that the agricultural sector has instigated a process of integrating climate concerns. However, these efforts will not lead to a large number of disruptive changes in the agricultural sector. While the EU is putting climate change firmly on the agricultural agenda, ranking the issue even higher than the environment, the Union’s primary goal is still to support the income of farmers. Hence, the EU’s intentions will likely lead to raising awareness of the issue of climate change in the context of agriculture but will not lead to any transformative changes in European agricultural policymaking.

The Impact

Climate change may affect the use of pesticides and their associated environmental and human health impacts. This study employs and modifies a partial equilibrium model of the US agricultural sector to examine the effects of alternative regulations of the pesticide and greenhouse gas emission externality. Simulation results indicate that without pesticide externality regulations and low greenhouse gas emission mitigation strategy, climate change benefits from increased agricultural production in the US are more than offset by increased environmental costs. Although the combined regulation of pesticide and greenhouse gas emission externalities increases farmers' production costs, their net income effects are positive because of price adjustments and associated welfare shifts from consumers to producers. The results also show heterogeneous impacts on preferred pest management intensities across major crops. While pesticide externality regulations lead to substantial increases in total water use, climate policies induce the opposite effect.

Goat milk production is an important agricultural resource in the Mediterranean basin. Market demands and scarcity of pastures during drought periods has led to farms becoming more intensive and based on imported concentrate feeds. The use of alternative feedstuffs from agro-industry can help decrease dependence on external concentrates, while preventing the environmental issues associated with livestock production and by-product disposal. From a life-cycle assessment perspective, we investigated the change on greenhouse-gas (GHG) emissions of replacing a conventional dairy goat diet in southern Spain with two alternative dietary strategies, including tomato waste or olive by-products silages. The effect on enteric methane emissions and milk productivity was assessed through specific feeding trials. Experimental data were integrated within a modelling framework comprising different submodels to describe the farm system and associated production chain. A new model describing carbon and nitrogen losses from solid waste was applied to estimate the emissions associated with the baseline scenarios for food by-product management. The assessment revealed that the two dietary strategies achieve GHG reductions (~12–19% per kg milk). In both cases, nitrous oxide and carbon dioxide emissions from crop production were partially reduced through the displacement of typical concentrate ingredients. An additional mitigation effect was obtained when including tomato wastes in the diet because it reduced the methane emissions from enteric fermentation. Results suggested that use of agro-industrial residues for feeding is a feasible mitigation option in this case. However, as organic by-products could have alternative uses (bioenergy, soil amendment), with different implications for land use and soil carbon stocks, a more complete overview of both scenarios is recommended. Potential trade-offs from non-GHG categories may play an important role in a decision-making process.

Agriculture is one of the main sources of greenhouse gas (GHG) emissions and has great potential for mitigating climate change. The aim of this study is to analyze the amount, dynamics of changes, and structure of GHG emissions from agriculture in the EU in the years 2005–2018. The research based on data about GHG collected by the European Environment Agency. The structure of GHG emissions in 2018 in the EU is as follows: enteric fermentation (45%), agricultural soils (37.8%), manure management (14.7%), liming (1.4%), urea application (1%), and field burning of agricultural residues (0.1%). Comparing 2018 with the base year, 2005, emissions from the agricultural sector decreased by about 2%, which is less than the assumed 10% reduction of GHG emissions in the non-emissions trading system (non-ETS) sector. The ambitious goals set by the EU for 2030 assume a 30% reduction in the non-ETS sector. This will require a significant reduction in GHG emissions from agriculture. Based on the analysis of the GHG emission structure and available reduction techniques, it was calculated that in this period, it should be possible to reduce emissions from agriculture by about 15%.

Greenhouse gas emission is a global ecological challenge since it affects climate change and complicates providing food security. Each country ought to care about mitigating Greenhouse gas emissions including CH4 and N2O originated from agriculture. In this context, first, the performed research focused on Ukrainian ranking among the world Greenhouse gas emitters offering a multi-criteria evaluation of total Greenhouse gas quantities in CO2 equivalent, those ones per capita and per km2 of countries’ land territories. These indictors were also applied to visual comparing involvement of Ukrainian economy and its agriculture in the international Greenhouse gas emissions. Second, to explore agricultural Greenhouse gas emission at the domestic level we studied regional contributions by basic source categories such as enteric fermentation, manure management, and synthetic fertilizers. The proposed horizontal and vertical analyses allow clarifying regional management priorities in reducing Greenhouse gas emissions. Third, for this purpose the conducted investigation specified the EU Member States which match Ukrainian condition by shares of Greenhouse gas emissions and outputs in animal and crop sectors. The found patterns will be the most reliable vectors of adopting effective agricultural practices beneficial for the environment protection and mitigating influence over climate change.

Methane Reduction

The New Zealand government has indicated that it will ratify the Kyoto Protocol, which means that legally binding targets will be set for reducing greenhouse gas (GHG) emissions. In "preferred" policies to achieve these targets, the agricultural sector will not be taxed directly but is expected to contribute to research leading to methane mitigation. A wide range of possibilities other than reducing livestock numbers exist for lowering livestock methane emissions: increasing the efficiency of animal production, exploiting betweenanimal variation; anti-methanogenic feed additives; dietary manipulation, including pasture composition modification; immunisation; and, manipulation of the rumen microbial ecosystem. Reduction in methane will not only have global environmental benefits, but also, as methane represents a loss of about 6% of an animal's energy intake, any reduction should be reflected in increased animal productivity per unit of intake. It should be possible to deliver a win/win situation with respect to methane reduction and increased productivity. Keywords: climate change, inventory, methane, mitigation, ruminants
