Grazing Livestock

AbstractThe landscape of the UK has been largely determined by past agricultural practices that have given rise to a range of anthropogenic habitats much valued by conservationists. Many of these have been created by, or for, grazing livestock. The suggestion that grazing and browsing animals were instrumental in ‘cyclical succession’ in the preagricultural period is also gaining ground. For these reasons the use of grazing animals in the management of conservation sites has become more common. Since its foundation in 1997 the Grazing Animals Project (GAP) has promoted and facilitated the use of grazing livestock in management of habitats for conservation.In 2001 GAP produced, in consultation with animal welfare organizations, A Guide to Animal Welfare in Nature Conservation Grazing. The practical advice in, and approach of, this document is potentially invaluable not only to conservation managers and graziers but also to all keepers of livestock. Another GAP publication, the Breeds Profiles Handbook, gives brief descriptions of 55 breeds of livestock known, or anticipated, to be of value in conservation grazing. Many of these are rare or traditional breeds, as these have the characteristics that enable the stock to thrive on the nutritionally relatively poor forage afforded by many conservation sites. These characteristics are often identified as ‘hardiness’ and ‘thriftiness’, but are poorly defined except through the practical experience of conservation managers.Conservation grazing is a relatively new niche, and one that cannot be filled by modern breeds or strains adapted to high-input, high-output systems. It is, therefore, a great opportunity for rare and traditional breeds, many of which developed in parallel with habitats now appreciated for their conservation value. This applies not only in the UK but also in other European countries. Moreover, recent developments, such as English Nature's Traditional Breeds Incentive for Sites of Special Scientific Interest, several grazing projects funded by the Heritage Lottery Fund and the Limestone Country Life Project, suggest that this niche is no longer confined to nature reserves.Conservation grazing can contribute to genetic conservation by:•Enabling an increase in numbers and wider distribution of rare and traditional breeds.•Allowing breeders to identify, and select, those individuals that fare best under relatively austere conditions.•Providing an outlet, or providing additional grazing, for stock that could not otherwise be kept.•Providing a market for good animals without reference to the showring.•Providing a refuge for rare breeds from threats such as that posed by the National Scrapie Plan.

The aim of the study was to present ammonia emissions from animal production on a regional scale in 2016. Emission estimates in particular regions were based on methodology developed by EEA in 2016 and applied in Poland by The National Centre for Emissions Management (NCEM). The conducted analyses were based on the size of livestock population, farming system and emission factors at every stage of manure management. The analysis showed substantial spatial differentiation of ammonia emissions from animal production. Voivodships that accounted for the biggest share in emissions from cattle farming were as follows: Mazowieckie, Podlaskie and Wielkopolskie. Estimated emissions in these voivodships amounted to: 47.4, 32.8 and 21.7 Gg NH3, respectively. The highest levels of ammonia emissions from pig production were identified in the region of Wielkopolska. Ammonia emissions in this voivodship amounted to 16.2 Gg NH3. The Wielkopolska region is also distinguished by the highest ammonia emissions from poultry production. The emissions equaled 11.4 Gg NH3 and accounted for 24.1% of total emissions in this region. The realization of reduction commitments for ammonia imposed by the NEC Directive depends on the introduction of a set of changes in livestock production: regarding the housing method, animal nutrition, fertilizer storage and application as well as dissemination of good agricultural practices aiming at ammonia emission reduction.

Abstract. As a major alkaline gas in the atmosphere, NH3 significantly impacts atmospheric chemistry, ecological environment, and biodiversity. Gridded NH3 emission inventories can significantly affect the accuracy of model concentrations and play a crucial role in the refinement of mitigation strategies. However, several uncertainties are still associated with existing NH3 emission inventories in China. Therefore, in this study, we focused on improving fertilizer application-related NH3 emission inventories. We comprehensively evaluated the dates and times of fertilizer application to the major crops that are cultivated in China, improved the spatial allocation methods for NH3 emissions from croplands with different rice types, and established a gridded NH3 emission inventory for mainland China with a resolution of 5 min × 5 min in 2016. The results showed that the atmospheric NH3 emissions in mainland China amounted to 12.11 Tg, with livestock waste (44.8 %) and fertilizer application (38.6 %) being the two main NH3 emission sources in China. Obvious spatial differences in NH3 emissions were also observed, and high emissions were predominantly concentrated in North China. Further, NH3 emissions tended to be high in summer and low in winter, and the ratio for the July–January period was 3.08. Furthermore, maize and rice fertilization in summer was primarily responsible for the increase in NH3 emissions in China, and the evaluation of the spatial and temporal accuracy of the NH3 emission inventory established in this study using the WRF-Chem and ground station- and satellite-based observations showed that it was more accurate than other inventories.
