“…In the mixed intensive systems of North America, manure is not yet fully recycled. There are places where manure is indirectly discharged into water bodies (Centner, 2011), or accumulated in constructed wetlands (Knight et al, 2000). Use of manure for biogas production is increasingly gaining attention, but it is not yet globally widespread (Cuellar and Webber, 2008).…”

Livestock play a significant role in rural livelihoods and the economies of developing countries. They are providers of income and employment for producers and others working in, sometimes complex, value chains. They are a crucial asset and safety net for the poor, especially for women and pastoralist groups, and they provide an important source of nourishment for billions of rural and urban households. These socio-economic roles and others are increasing in importance as the sector grows because of increasing human populations, incomes and urbanisation rates. To provide these benefits, the sector uses a significant amount of land, water, biomass and other resources and emits a considerable quantity of greenhouse gases. There is concern on how to manage the sector's growth, so that these benefits can be attained at a lower environmental cost. Livestock and environment interactions in developing countries can be both positive and negative. On the one hand, manures from ruminant systems can be a valuable source of nutrients for smallholder crops, whereas in more industrial systems, or where there are large concentrations of animals, they can pollute water sources. On the other hand, ruminant systems in developing countries can be considered relatively resource-use inefficient. Because of the high yield gaps in most of these production systems, increasing the efficiency of the livestock sector through sustainable intensification practices presents a real opportunity where research and development can contribute to provide more sustainable solutions. In order to achieve this, it is necessary that production systems become market-orientated, better regulated in cases, and socially acceptable so that the right mix of incentives exists for the systems to intensify. Managing the required intensification and the shifts to new value chains is also essential to avoid a potential increase in zoonotic, food-borne and other diseases. New diversification options and improved safety nets will also be essential when intensification is not the primary avenue for developing the livestock sector. These processes will need to be supported by agile and effective public and private institutions.

“…The CAFO regulations adopted by the EPA in 2003 were contentious and the EPA was sued by both agricultural and environment groups that claimed the new provisions violated federal law (Centner, 2011). Both groups were correct with some of their arguments, and the EPA was again forced to amend its federal CAFO provisions (Centner and Newton, 2008).…”

The development of shale gas resources in the United States has been controversial as governments have been tardy in devising sufficient safeguards to protect both people and the environment. Alleged health and environmental damages suggest that other countries around the world that decide to develop their shale gas resources can learn from these problems and take further actions to prevent situations resulting in the release of harmful pollutants. Looking at U.S. federal regulations governing large animal operations under the permitting provisions of the Clean Water Act, the idea of a permitting program is proposed to respond to the risks of pollution by shale gas development activities. Governments can require permits before allowing the drilling of a new gas well. Each permit would include fluids and air emissions reduction plans containing best management practices to minimize risks and releases of pollutants. The public availability of permits and permit applications, as occurs for water pollution under various U.S. permitting programs, would assist governments in protecting public health. The permitting proposals provide governments a means for providing further assurances that shale gas development projects will not adversely affect people and the environment.

“…For example, although legislation is often regarded as an important means of achieving institutional adaptation to implement new or evolving actions (see Cortner and Moote, 1994); there was disagreement over whether CEAM should be managed through legislation or through more voluntary means. To reduce feed lot contamination of water sources in the US, for example, Centner (2011) argues the benefits of voluntary programs and stakeholder collaboration over inflexible regulatory regimes and the judicial system. At a minimum, however, some form of enabling legislation was identified in the SSW as a necessary component.…”
