Sagri Co., Ltd. Obtains Patent for Technology That Estimates and Calculates Farmland GHG Emissions and Supports Farming Improvements

~Contributing to Decarbonization in the Agricultural Sector by Remote Sensing Data~

Sagri Co., Ltd. (Headquarters: 725-1 Joraku, Hikami-cho, Tamba-shi, Hyogo Prefecture; CEO: Shunsuke Tsuboi) announces that it has obtained a patent (Patent No. 7761891) for a “Program, Information Processing Device, and Method.” This technology estimates and calculates greenhouse gas (GHG) emissions from data obtained by scanning farmland and provides information to support farming improvements.

Background

In recent years, reducing greenhouse gas (GHG) emissions has become a global challenge due to growing environmental awareness. In the agricultural sector, farming methods with low GHG emissions and minimal environmental impact are being promoted. There is a strong demand from social requirements, legal regulations, and food companies that procure crops to calculate and manage GHG emissions.

However, in actual farming practice, calculating these emissions has been difficult because they fluctuate significantly depending on farming conditions. Furthermore, even when emissions could be calculated, it remained challenging to obtain information on specific improvement measures.

Patent Overview

The newly registered patent concerns technology developed to solve these challenges. This technology enables the accurate calculation of GHG emissions in agriculture and provides specific information regarding farming conditions.

Its main features are as follows:

1. Acquisition and Analysis of Scan Data: A computer acquires scan data obtained from scanning farmland, such as satellite imaging data.
2. Estimation of Farming Conditions: The acquired scan data is analyzed to estimate farming conditions for each farmland (or for each field demarcated into predetermined areas). This includes details such as crop type, soil conditions (nitrogen and carbon content, etc.), and fallow land status.
3. Calculation of GHG Emissions: Based on the estimated farming conditions, the system estimates and calculates GHG emissions (such as carbon dioxide, methane, and nitrous oxide) from the farmland.
4. Provision of Information (Improvement Proposals): Based on the estimation results, the system acquires and outputs useful information to the user’s terminal device. This includes time-series changes in GHG emissions, specific farming improvement proposals for reducing emissions, and recommendations for farmland improvements suitable for food companies seeking to procure specific crops.

Future Outlook

Sagri Co., Ltd. will leverage this patented technology through our “Sagri Vision” service to strongly promote the “visualization” and reduction of GHG emissions in the agricultural sector.

We will support producers in adopting environmentally friendly farming activities and provide businesses that handle agricultural products with solutions that contribute to enhancing the sustainability of the entire supply chain.
