Throughout the world, emerging countries and developed countries alike are striving for zero emissions and the construction of smart cities to achieve sustainable societies. In step with this trend, the United Nations is promoting its Sustainable Development Goals (SDGs), which cover activities in 17 different areas. Looking at the Nippon Koei Group’s businesses, we can see that we are already contributing in various ways to achieving all of these SDGs.

In NK-Innovation 2021, we aim to flexibly incorporate the SDGs into our businesses, and make them a common language for behavior within the Company. In other words, we will adopt the SDGs, a global lingua franca, in our day-to-day work as the platform of our business, and maintain an attitude of making better proposals by keeping in mind how each project will contribute to achieving the SDGs. We believe that we should accurately gauge the position of our projects in the relationships between various issues, and mobilize our technologies to solve those issues.

To realize this kind of value creation, we added “innovation” to the title of the new medium-term management plan. Looking at the future environment, open innovation will become the norm, and we will need to strongly promote new combinations of technologies and knowledge both in and outside the Company, in addition to existing frameworks. As a concrete first step, we will focus on establishing a one-stop marketing system. The five business segments and the Nippon Koei Group overall will cooperate to build a marketing platform that is capable of responding to diverse market needs, and will acquire new customers by leveraging that platform.

Initiatives to achieve the SDGs at our Group have been introduced as examples of companies engaged in the SDGs on the Ministry of Foreign Affairs of Japan website and the Global Compact Network Japan website.

Darfur Three State Peace Building Project in Sudan

The Darfur Three State Peace Building Project is pursuing measures to help the over 1.7 million Sudanese people who have no choice but to live in camps for Internally Displaced Persons (IDP) in Darfur, Sudan due to armed conflicts and environmental degradation issues in recent years.

Koei Research & Consulting Inc., a Nippon Koei Group company, took part in the pilot project to strengthen government service capabilities and systems for health, water and employment centers in three states of Darfur, Sudan.

The sector of health and water established agreements between community health and water committees, selecting female committee members and ensuring speaking opportunities for all relevant communities (total 54 communities). The employment centers positioned training for women as a key field in the Darfur vocational training policy and formulated training plans for women in each state.

This provides public services tailored to the needs of the local people while at the same time improving trust in the local state government by enhancing administrative capabilities of the local state governments.

Quantitative Results

Project to Investigate Measures to Combat Invasive Vegetation at Otaki Dam

The project drafted overall extermination and prevention plans for extermination work of invasive plant species (Madagascar ragwort and Lance-leaved tickseed) living in and around the Otaki Dam reservoir in the Yoshino district of Nara prefecture, considering the growth characteristics of relevant introduced species and the conversion of vegetation after extermination (promoting a shift to locally native plants).

Sustainable management methods able to be done by dam administrators after formulation of the plans not only became a local model project but the materials used to convert the vegetation also took advantage of native seedlings that could be harvested in the project area (downy ground fern, etc.), local topsoil, and chips of dam driftwood (finely crushed wood drifting to the dam) to conserve the environment and cut costs.

In addition, the work helped coexistence with the local people from the conservation of seedlings planted as a measure to prevent damage by deer feeding which had been a challenge in the respective region to the creation of materials to raise awareness about the region.

Quantitative targets The extermination work will continue for three years after the initial three-year preparations (initial extermination and conversion of vegetation from 2019 to 2021) to eliminate non-native vegetation by 2024.
Plan scope: 60 areas (2.1 ha)
Priority areas: 11 locations (Over 1000 plants/location)
Contract period October 2018 to March 2019 (6 months)
