Abstract(s)
High livestock densities and the subsequent generation of large quantities of
manure, in some areas of the world, generate hotspots of increased environmental
risks through ammonia (NH3) and greenhouse gas (methane, CH4; nitrous oxide,
N2O) emissions. Livestock production is therefore facing increased pressures
from society to comply with environmental legislation, so that systems are managed in a sustainable and environmentally friendly manner. A
key solution to minimize or avoid environmental and health concerns associated
with manure is to ensure appropriate feeding strategies as well as manure
management techniques through the entire manure management chain from
animal housing, storage of manure, treatment operations and finally application
to soil. An integrated framework is needed to allow practical, cost-effective
on-farm strategies to be selected, which will reduce losses and improve resource
use efficiencies.
In this chapter, we first analyse the contribution of manure management to
NH3 and GHG emissions with focus on bovine, pig and poultry manure. We then
describe different mitigation options for reducing gaseous emissions along the
manure management chain in terms of their efficiency to decrease NH3 and GHG
emissions and their applicability. Finally, we present and assess two case studies of integrated manure management strategies to reduce gaseous emissions.
