Efforts have been made in recent years to improve knowledge about soil greenhouse gas (GHG) fluxes from sub-Saharan Africa. However, data on soil GHG emissions from smallholder coffee-dairy systems have not hitherto been measured experimentally. This study aimed to quantify soil GHG emissions at ...

Multi-scale measurements show limited soil greenhouse gas emissions in Kenyan smallholder coffee-dairy systems
Global rice production systems face two opposing challenges: the need to increase production to accommodate the world's growing population while simultaneously reducing greenhouse gas (GHG) emissions. Adaptations to drainage regimes are one of the most promising options for methane mitigation in ...

The effective mitigation of greenhouse gas emissions from rice paddies without compromising yield by early-season drainage
Greenhouse gas (GHG) mitigation strategies are often constrained by rice farmers’ preferences, therefore an
assessment of mitigation strategies taking farmers’ constraints into consideration, are important for their pos- sible adoption. The field experiments were conducted for two continuous rice...

Mitigating CH4 and N2O emissions from intensive rice production systems in northern Vietnam: Efficiency of drainage patterns in combination with rice residue incorporation
Elevated greenhouse gas (GHG) emissions, particularly of methane (CH4) from flooded rice production systems contribute to global warming. Different crop management strategies, such as drainage of paddy soils and climate-smart residue management, are essential in order to mitigate GHG emissions fr...

Shifting cultivation is practiced by millions of farmers in the tropics and has been accused of causing deforestation and keeping farmers in poverty. The assumed positive relationship between fallow length and crop yields has long shaped such negative opinions on the sustainability and environmen...

Manure, biogas digestate and crop residue management affects methane gas emissions from rice paddy fields on Vietnamese smallholder livestock farms
Climate-smart approaches have gained momentum in tropical, agricultural development. However, to date, few studies have examined whole-farm greenhouse gas (GHG) balances in smallholder crop-livestock systems. This study aimed to quantify GHG balances at farm-scale, identify GHG hotspots and asses...

While an increasing number of large food companies commit themselves to source only certified cocoa, research on the impacts of certification on cocoa farmers is falling behind. We investigate how Rainforest Alliance (RA) certification of smallscale cocoa farmers in Ghana has affected both the fi...
