“…Lou et al, (2012) also reported that soil electrical conductivity increased significantly in comparison with open field condition mainly due to the reckless application of nitrogenous fertilizer with higher rate in the greenhouses. Similar findings were also reported by several researchers (Cao et al, 2012, Gao et al, 2012. Organic carbon and magnesium content were statistically significant at 5% level of significance, under polyhouse and open condition in different locations of Sirmaur district (Table 4).…”

Ongoing intensification and specialisation of livestock production lead to increasing volumes of manure to be managed, which are a source of the greenhouse gases (GHGs) methane (CH 4 ) and nitrous oxide (N 2 O). Net emissions of CH 4 and N 2 O result from a multitude of microbial activities in the manure environment. Their relative importance depends not only on manure composition and local management practices with respect to treatment, storage and field application, but also on ambient climatic conditions. The diversity of livestock production systems, and their associated manure management, is discussed on the basis of four regional cases (Sub-Saharan Africa, Southeast Asia, China and Europe) with increasing levels of intensification and priorities with respect to nutrient management and environmental regulation. GHG mitigation options for production systems based on solid and liquid manure management are then presented, and potentials for positive and negative interactions between pollutants, and between management practices, are discussed. The diversity of manure properties and environmental conditions necessitate a modelling approach for improving estimates of GHG emissions, and for predicting effects of management changes for GHG mitigation, and requirements for such a model are discussed. Finally, we briefly discuss drivers for, and barriers against, introduction of GHG mitigation measures for livestock production. There is no conflict between efforts to improve food and feed production, and efforts to reduce GHG emissions from manure management. Growth in livestock populations are projected to occur mainly in intensive production systems where, for this and other reasons, the largest potentials for GHG mitigation may be found.Keywords: methane, nitrous oxide, storage, treatment, farm model ImplicationsLivestock manure is a source of greenhouse gas (GHG) emissions, mainly as methane and nitrous oxide. GHG emissions are biogenic and regulated by manure characteristics, and therefore emissions can be manipulated via handling, treatment and storage conditions. Globally, livestock production systems vary widely, and this is also true for GHG mitigation potentials, but generally efforts to conserve nutrients in manure for crop production will also reduce GHG emissions. Future growth in livestock production is projected to occur mainly in confined animal feeding operations, which also appear to have the greatest potential for GHG mitigation. IntroductionSince the mid 20th century, there has been a growing pressure on land resources for production of food and feed for livestock and, increasingly, crops for energy production (Hoogwijk et al., 2005). To fulfil the demand for meat, milk and eggs, livestock production in developing countries is expanding, especially in peri-urban areas (Gerber et al., 2005), and worldwide becomes more specialised (Steinfeld et al., 2006). In consequence of these trends, increasing volumes of livestock manure are produced, which are a source of greenhouse gases (GHGs) contributing t...

[148 words]In China intensification of agriculture has been achieved at a cost to the environment. The extension service is the leading public resource to address this but remains focused by a historic national ethos for food security, production and economic growth, whilst its administrative structure is hierarchical, slow to change and lacking in relevant functional integration. Investigation of three case study farming systems identifies how to rebalance productivity with stewardship of farm inputs and natural resources. Substance flow analyses for each case demonstrate that crop nutrient management can potentially be improved to reduce environmental risk without yield loss. Complementary stakeholder surveys and social network analyses identify barriers to change relating to the knowledge, attitudes, practices and operational constraints of farmers and extension agents, and to the structure and performance of agricultural knowledge and innovation systems. This combination of analyses offers an original synthesis of needs, planning priorities and strategies. In China intensification of agriculture has been achieved at a cost to the environment.
