Reliable quantification of nitrous oxide emission is a key to assessing efficiency of use and environmental impacts of N fertilizers in crop production. In this study, N2O emission and yield were quantified with a database of 853 field measurements in 104 reported studies and a regression model w...

Re-assessing nitrous oxide emissions from croplands across Mainland China
This report provides an overview of the United Nations Framework Convention on Climate Change (UNFCCC) reporting process for national greenhouse gas (GHG) inventories with particular focus on the methodology used for estimating direct nitrous oxide (N2O) emissions from mineral fertiliser. Example...

Conservation agriculture (CA) can increase resilience to climate change and has the potential
to contribute to climate change mitigation. The benefits of CA are highly site- specific. Innovative approaches are needed to overcome barriers for uptake of CA by smallholders.

The world population is projected to increase to 9–10 billion by 2050, during which time it will be necessary to reduce anthropogenic greenhouse gas emissions to mitigate climate change. The particular challenge this places on agriculture is to identify practices which ensure stable and productiv...

Identifying secure and low carbon food production practices: a case study in Kenya and Ethiopia
It is remarkable that despite wide-ranging, in-depth studies over many years, almost no conservation agriculture (CA) studies consider gender and gender relations as a potential explanatory factor for (low) adoption rates. This is important because CA demands new ways of working with the farm sys...

Zero-tillage, residue management and precision nutrient management techniques are being promoted in the rice–wheat (RW) production system of Indo-Gangetic Plains (IGPs) to enhance climate change adaptation and increase food production. These management practices may also influence greenhouse gas ...

Conservation agriculture (CA), comprising minimum soil disturbance, retention of crop residues and crop diversification, is widely promoted for reducing soil degradation and improving agricultural sustainability. It is also claimed to mitigate climate change through soil carbon sequestration: we ...

This article reviews the published evidence of the climatic risks faced by smallholder farmers in eastern Africa and the adaptation strategies these farmers have so far adopted. In addition, the study draws on two detailed case studies in Kenya for a better understanding of the nuances of climate...

Greenhouse gas emissions from fertilizer usage in sub-Saharan Africa are currently low due to low application rates of nitrogen fertilizers. As African countries begin to implement their Nationally Determined Contributions to the Paris Agreement, there is an opportunity to improve crop productivi...
