Small-scale spatial variability in soil carbon dioxide (CO2) and nitrous oxide (N2O) fluxes poses serious challenges to the experimental design, and number of gas samples needed to provide a reliable estimate of flux usually exceeds analytical capacities. We pooled gas samples –analogously to soi...

Gas pooling: a sampling technique to overcome spatial heterogeneity of soil carbon dioxide and nitrous oxide fluxes
Globally, agriculture is directly responsible for 14% of annual greenhouse gas (GHG) emissions and induces an additional 17% through land use change, mostly in developing countries (Vermeulen et al 2012). Agricultural intensification and expansion in these regions is expected to catalyze the most...

Towards a protocol for quantifying greenhouse gas emissions and evaluating mitigation options in smallholder farming systems
Legume tree-based farming systems sit at a crucial nexus of agroecological sustainability. Their capacity to support microbial N2 fixation can increase soil nitrogen (N) availability and therefore improve soil fertility, crop yields, and support long-term stewardship of natural resources. However...

Agroforestry with N2-fixing trees: Sustainable development's friend or foe?
Evidence exists to support CSA programming on the most widely cultivated crops (e.g. maize), and most common agricultural practices (e.g. fertilizer addition) in Tanzania. However, products and places central to rural livelihoods such as livestock, coastal drylands, and humid regions near Lake Vi...

Efficient data collection from rural households – is RHOMIS for you?
Depuis 2009, des milliards de dollars ont été investis dans des programmes d’AIC dans le but d’aider les petits exploitants à augmenter leur productivité tout en s’adaptant aux changements climatiques et en contribuant à les atténuer. Cependant, l’AIC a récemment dépassé les cercles de l’aide au ...

Alrededor de un tercio de los países de América Latina han expresado la intención de utilizar la agroforestería para cumplir con sus compromisos climáticos nacionales.
A pesar de este interés, barreras técnicas e institucionales a menudo impiden que la agroforestería sea incluida y tomada en cuen...

This paper offers an overview of how climate change is already affecting farmers across eastern and southern Africa, and how it will continue to affect them in the future. The rising temperatures and increased rainfall variability associated with climate change are undermining the livelihoods and...

Demand for tools to rapidly assess greenhouse gas impacts from policy and technological change in the agricultural sector has catalyzed the development of ‘GHG calculators’— simple accounting approaches that use a mix of emission factors and empirical models to calculate GHG emissions with minima...

Limits of agricultural greenhouse gas calculators to predict soil N2O and CH4 fluxes in tropical agriculture
Climate variability is a major source of risk to smallholder farmers and pastoralists, particularly in dryland regions. A growing body of evidence links climate-related risk to the extent and the persistence of rural poverty in these environments. Stochastic shocks erode smallholder farmers' long...
