This study comprises a set of methane emission measurements in rice fields located in the four agro-ecological zones of the Mekong River Delta (MRD), namely the zones with (i) alluvial soils, (ii) salinity intrusion, (iii) deep flood, and (iv) acid sulfate soils. These zones have very distinct bi...

Methane emission from rice cultivation in different agro-ecological zones of the Mekong river delta: seasonal patterns and emission factors for baseline water management
Climate change has many facets, including changes in long-term trends in temperature and rainfall regimes with increasing year-to-year variability and a greater prevalence of extreme events. The effects of these changing conditions on agriculture are already being seen, yet there are still consid...

Climate-smart Agriculture (CSA) represents a commonly accepted term in referring to intended changes in agriculture production addressing climate change. Although specific definitions may vary, CSA is typically conceived as having three pillars, namely Adaptation, Food Security and Mitigation. Th...

Participatory research allows groups and individuals to reflect and decide on their societal issues together. Such research was employed in Tra Hat Climate-Smart Village (CSV) in Vietnam to see if specific climate-smart agriculture (CSA) techniques could be adopted in the village. In line with th...

A growing scarcity of irrigation water could progressively lead to changes in rice production to systems using less irrigation water for rice or more crop diversification. A shift from current production of rice on flooded soils to production of rice on non-flooded soil with water-saving irrigati...

Water-saving technologies such as alternate wetting and drying (AWD) provide a way to change practices to improve the livelihoods of many rice farmers and AWD is regarded as one of the more important rice cultivation methods that can dramatically save freshwater irrigation in this century. AWD no...

Rice is produced in a wide range of locations and under a variety of climatic conditions, from the wettest areas in the world to the driest deserts. It is produced along Myanmar’s Arakan Coast, where the growing season records an average of more than 5,100 mm
of rainfall, and at Al Hasa Oasis in ...

Methane (CH4) production and emission from three rice-growing soils (Luisiana, Maahas and Pila) of Luzon Island in the Philippines were estimated by incubation and pot culture studies, respectively, to understand their interrelationship. Topsoil (0 20 cm depth) and subsoil (30 50 cm depth) were u...
