農地において支柱を立てて上部空間に太陽光発電設備を設置し、下部空間では営農を継続しながら発電を行う営農型太陽光発電（ソーラーシェアリング）は、再生可能エネルギー導入量の拡大が見込めること、農業者の収入拡大による農業経営の改善や6次産業化の推進も期待できることから、政府として推進する方針が掲げられ、様々な制度で導入促進が図られている。 例えば、再生可能エネルギーの導入促進のために固定価格買取制度が導入されているが、営農型太陽光発電と野立太陽光発電で買取価格が区別されていない。しかしながら、両者は費用構造や事業リスクが異なり、導入によってもたらされる便益も異なることから、その性質に則して営農型太陽光発電の推進のための施策が導入されることが望ましい。...

Information and Communication Technologies (ICT) have been identified as potential enablers for alternative forms of sharing surplus food to prevent food loss and waste. Food sharing platforms can also provide an entry point to the sustainability transition by encouraging its users to confront the systemic causes of unsustainable and inequitable...

The widespread adoption of low emissions technologies in rapidly developing countries is critical to resolving the climate emergency.1 However, many fast growing economies lack the energy efficient, renewable, and other advanced technologies needed to mitigate climate change. Technology transfer could help address these countries need. Yet the...

北九州市海外水ビジネス推進協議会（KOWBA）は2020年に設立10周年を迎えた。その節目に際してKOWBAが作成した記念誌の一部として「北九州市が取り組む海外水ビジネス」を執筆した。これは「持続可能な社会への挑戦－北九州市とアジア都市との連携」（2018年7月）と「北九州における水ビジネス海外展開の歴史と発展」（2020年3月）に基づいた内容となっている。IGES北九州アーバンセンターとして北九州市の国際政策を20周年以上見つめてきた立場から、北九州市の海外水ビジネス、並びにKOWBAの役割や未来について論じている。

Enhanced collaboration with countries with advanced technologies is essential to closing greenhouse gas (GHG) mitigation gaps in developing countries’ energy consuming and producing sectors. However, traditional models of technology transfer tend to focus on the sale of expensive technologies to developing countries, often subsidised through aid or...

Negombo City is one of the fastest growing tourist destinations in Sri Lanka. It is the major commercial and transport centre, and main health service provider for the region. However, municipal solid waste management is a pressing concern for Negombo due to expanding urbanization, increasing income, lack of public awareness, changes in consumption...

Lack of robust data to assess the effects of different policies may hamper the design and implementation of effective solutions to reduce traffic emissions. This study analyzed the emissions of passenger fleets in Bandung, Indonesia, illustrated with three emission scenarios against the 2015 baseline. Local surveys were conducted to get traffic...

A large proportion of Asia’s urban population is served by informal modes of transport known as paratransit. Many of the vehicles in this informal sector contribute to rising air pollution and greenhouse gas (GHG) emissions. Energy-efficient technologies could make paratransit environmentally sustainable. However, the purchase and use of clean...

Semarang became the first Asian city to release a Resilience Strategy on May 23rd, 2016. Among the document’s six pillars, number 4 is Integrated Mobility. This pillar aims to enhance the performance of the city’s mobility systems by promoting the use, improving the service quality, and enhancing the management of the public transportation network...
