Automated chamber systems

Automated chamber systems


Automated chamber systems are useful tools in the investigation of soil-atmosphere trace gas exchange and its response to changes in the environmental conditions. Read more

Eddy covariance

Eddy covariance


The eddy covariance (EC) system is an effective tool that IRRI uses in ensuring that the mitigation and adaptation options that the institute develops to minimize the impacts of climate change on rice production have also minimal environmental footprints. Read more

Manual chamber method


In the manual closed chambers, the chamber includes rice plants, the base is fixed in the field, gas is taken with syringe stored in vials, and analysis is done via gas chromatography. Read more

GHG Calculator


Greenhouse gas (GHG) assessment calculators have been created for a number of reasons, such as raising awareness to GHG emissions, reporting GHG emissions, project evaluation for change in GHG emissions, and market and product oriented calculators designed to estimate GHG emissions per product. Read more

Measurement Guidelines

Measurement guidelines


This measurement guidelines was commissioned by the Secretariat of the Agriculture, Forestry and Fisheries Research Council of the Ministry of Agriculture, Forestry and Fisheries of Japan through the international research project “Technology development for circulatory food production systems responsive to climate change to support the goals and objectives of the Paddy Rice Research Group of the Global Research Alliance on Agricultural Greenhouse Gases (PRRG-GRA).
