How tree quantification works
Project data are submitted by local quantifiers who make visits to the tree groves planted by the TIST Small Groups. They are trained in the use of measurement and GPS technology on smart phones. The group's trees are counted and, when old enough, circumferences taken. The information collected is used to calculate CO2 sequestered based on the growth and age of the trees. Tree data is logged by GPS location into the smart phone and uploaded to the web. The quantifier visits are also an opportunity to answer questions, share information and provide encouragement.
There are additional local desk audits as results are uploaded to the web. There are then local audits done. Finally, third party verifiers evaluate the results and the additional benefits of the trees, such as fruit, nuts, medicines, animal fodder, shade, fuelwood and other effects of the returning biodiversity.
TIST provides detailed and regular accounting of the location, size, and species of trees being planted. TIST also is assessing the impact of the program on food supply, health, and other human factors. Analysis of all data are provided to help improve program operations and to report to stakeholders.
In addition, TIST assesses the impacts of conservation farming on food supply and the impacts of the total TIST program on other human factors. Third party verification has shown far greater than expected benefits for families and local communities including health, nutrition, and economic well being.
