This paper describes MOLES 1.0, an integrated land-use and transport model developed with Object-Oriented Programming principles in order to combine selected characteristics from Spatial Computable General Equilibrium and microsimulation models. MOLES 1.0 models the links between urban land use, mobility patterns, urban economic activities and their environmental impacts, in particular air pollution and emissions of greenhouse gases.
This report explores effective policy solutions to the current and future challenges related to food security in the countries of the Association of Southeast Asian Nations (ASEAN). While robust GDP growth, rising agricultural productivity and output, and strong growth in agricultural incomes have all contributed to vast improvements in the food security of the region, 60 million people remain undernourished. ASEAN governments have therefore justifiably kept food security as a policy priority. The regional policy architecture set out in ASEAN frameworks provides sound guidance, yet some of the current policies adopted by members are not helping to address food insecurity and its causes, including the formidable challenges related to climate change and the need for continued growth in sustainable food production to feed growing populations. This report puts forward a number of policy recommendations to ensure that the ASEAN agricultural and fisheries sectors contribute effectively and efficiently to ensuring regional food security.
This report provides an analysis of how climate change damages may affect international trade in the coming decades and how international trade can help limit the costs of climate change. It analyses the impacts of climate change on trade considering both direct effects on infrastructure and transport routes and the indirect economic impacts resulting from changes in endowments and production.
This report provides insights on the political economy of biodiversity related policy reforms. It draws on existing literature and four new case studies covering the French tax on pesticides, agricultural subsidy reform in Switzerland, EU payments to Mauritania and Guinea-Bissau to finance marine protected areas via conservation trust funds, and individually transferable quotas for fisheries in Iceland. Each case study focusses on the drivers of reform, the types of obstacles encountered, key features of the policy reform, and the lessons learned from the reform experience.
This report describes the development of the green bond market as an innovative instrument for green finance, and provides a review of policy actions and options to promote further market development and growth. Since 2007-08, so-called “green bonds” have emerged and the market has risen from USD 3 billion in 2011 to USD 95 billion in issuance in 2016. For policy makers, the report proposes a framework for understanding potential directions of bond market evolution, increased convergence of rules and definitions, and quantitative analysis of the potential contribution that bond markets can make to a low-carbon transition.
Les pays en développement sont affectés de manière disproportionnée par la hausse des pertes liées aux événements climatiques extrêmes. Sur la base d’études de cas en Colombie et au Sénégal, ce document examine comment les pays utilisent la protection financière dans le cadre de leurs approches de gestion des risques climatiques.
After decades of regulation and investment to reduce point source water pollution, OECD countries still face water quality challenges (e.g. eutrophication) from diffuse agricultural and urban sources of pollution, that is disperse pollution from surface runoff, soil filtration and atmospheric deposition. The relative lack of progress reflects the complexities of controlling multiple pollutants from multiple sources, their high spatial and temporal variability, associated transactions costs, and limited political acceptability of regulatory measures. This report outlines the water quality challenges facing OECD countries today, presents a range of policy instruments and innovative case studies of diffuse pollution control, and concludes with an integrated policy framework to tackle diffuse water pollution. An optimal approach will likely entail a mix of policy interventions reflecting the basic OECD principles of water quality management – pollution prevention, treatment at source, the polluter pays and beneficiary pays principles, equity, and policy coherence.
La population néo-zélandaise jouit d’une haute qualité de vie environnementale et peut accéder à des espaces naturels intacts. Le modèle de croissance du pays, largement fondé sur l’exploitation de ressources naturelles, commence toutefois à montrer ses limites écologiques du fait de l’aggravation des émissions de gaz à effet de serre et de la pollution de l’eau, comme le note l’OCDE dans un nouveau rapport.
Since the financial crisis, infrastructure investment has moved up the political agenda in most countries – now also including the USA. Asia is often seen as the world’s infrastructure laboratory, with massive construction of transport and energy projects. This article discusses infrastructure investment, private finance, and institutional investors in Asia from a global perspective.
This study was one of the first attempts to evaluate and quantify the benefits of transboundary co-operation between Georgia and Azerbaijan. A specific framework for inventorying these benefits, taking into account all the different dimensions of transboundary water management, was built and applied to the major transboundary water bodies.
