Nitrous oxide (N2O) is the most important greenhouse gas produced by agricultural soils and is a byproduct of microbial nitrification and denitrification processes. The N2O emission rates depend on soil, climatic and management factors. The objectives of this study were i) to evaluate N2O emissions during a barley crop period and its subsequent barley-maize interperiod, under two management systems, and ii) to relate the N2O flux rates with soil mineral N content, waterfilled pore space (WFPS) and soil temperature.
Approaches to food security primarily focus on technological solutions, seeking to produce more food, preferably with fewer resources. It has been argued that access to food involves issues of resource distribution and social marginalization. Governance is seen as one of the keys to redressing the institutional inequity that affects resource distribution. Rural women's empowerment is seen as a means to reduce social marginalization and to hasten progress towards hunger eradication and gender equitable institutions.
