Too often modern cities and suburbs are disorganized places where most new development makes daily life less pleasant, creates more traffic congestion, and contributes to climate change. This trend has to change; and our course is going to show you how.

Ecodesign means integrating planning, urban design and the conservation of natural systems to produce a sustainable built and natural environment. Ecodesign can be implemented through normal business practices and the kinds of capital programs and regulations already in use in most communities. We will show you how ecodesign has already been used for exceptional projects in many cities and suburbs—from Hammarby Sjöstad in Stockholm to False Creek North in Vancouver to Battery Park City in Manhattan, as well as many smaller-scale examples that can be adopted in any community. Cities and suburbs built according to ecodesign principles can and should become normal, instead of just a few special examples, transforming urban development into desirable, lower-carbon, compact and walkable communities and business centers.

As this course describes specific solutions to the vexing urban challenges we all face, course participants can see how these ideas might be applied in their own area. Participants will learn the conceptual framework of ecodesign, see many real, successful examples, and come to understand the tools, processes, and techniques for policy development and implementation.

Ecodesign thinking is relevant to anyone who has a part in shaping or influencing the future of cities and suburbs – citizens, students, designers, public officials, and politicians. At the conclusion of the course participants will have the tools and strategies necessary to advocate policies and projects for a neighbourhood or urban district using the ecodesign framework.

There are many practical applications of radiation and radioactivity in various fields, including medical, scientific, and industrial activities. In some parts of Japan, people continue to experience environmental radioactivity caused by the nuclear accident at the Fukushima Daiichi Nuclear Power Plant on a daily basis. Understanding the basic science of radiation and radioactivity will form the base of the course, with specific examples from Japan and elsewhere in the world to illustrate concepts.

This course introduces radiochemistry, radiation detection and measurement, and explores radiation’s effect on the human body. You will gain a greater understanding of radioisotopes, radioactive decay, radiations, radiation interaction with matter, and ways to assess radiation exposure. We will explore applications of radiation through various examples including nuclear power generation, diagnostic and therapeutic uses in medicine, and other scientific and industrial uses. Lastly, we will discuss the fate and transport of radioactive cesium in Fukushima in relation to chemical and physical properties of the radionuclide.

Humanity faces an immense challenge: providing abundant energy to everyone without wrecking the planet. If we want a high-energy future while protecting the natural world for our children, we must consider the environmental consequences of energy production and use. But money matters too: energy solutions that ignore economic costs are not realistic—particularly in a world where billions of people currently can’t afford access to basic energy services. How can we proceed?

Energy Within Environmental Constraints won’t give you the answer. Instead, we will teach you how to ask the right questions and estimate the consequences of different choices.

This course is intended for a diverse audience. Whether you are a student, an activist, a policymaker, a business owner, or a concerned citizen, this course will help you start to think carefully about our current energy system and how we can improve its environmental performance.

This course:

• Covers engineering, environmental science, and economics to enable critical, quantitative thinking about our energy system
• Focuses on a working understanding of energy technologies, rich in details of real devices and light on theory; you won’t find any electrodynamics here but will find enough about modern commercial solar panels to estimate if they would be profitable to install in a given location
• Covers environmental impacts of the energy system, focusing on air pollution, climate change, and land use
• Emphasizes costs: the cascade of capital and operating costs from energy extraction all the way through end uses
• Emphasizes quantitative comparisons and tradeoffs: how much more expensive is electricity from solar panels than from coal plants, and how much pollution does it prevent?  Is solar power as cost-effective an environmental investment as nuclear power or energy efficiency?  And how do we include considerations other than cost?

Please note that this is an abridged course, equivalent to roughly half of a full semester-long undergraduate course.  See the syllabus for topics that we include and a list of some we exclude.

Feeding nine billion people in 2050 without exhausting the planetary reserves is perhaps the greatest challenge mankind has ever faced. This environmental studies course will examine the principles of production ecology and the ‘availability pillar’ of global food security that lie at the heart of food production, which can be applied to both crops and animal production. This course will discuss why yields in some parts of the world are lagging behind and identify the agro-ecological drivers that shape the wide diversity of production systems.

Furthermore, key issues relating to the closing of yield gaps and the difference in visions of sustainability will be explored.

This online course will be of great interest to international students and those with varied educational backgrounds, both professionally and culturally, to enrich their views and action perspectives related to global food security and food systems. Professor Ken E. Giller will introduce learners to crop production and underlying bio-physical principles in order to identify constraining factors in yield formation. He will explain how to assess yield gaps at the level of fields and production systems around the world, contributing to efficient resource management. Wageningen University and Research, through its unique systems-based approach to food systems, adds the phase of primary production to the broad context of global food security.

This interdisciplinary course explores the complex interactions between poverty, rural livelihoods, and forest resources in developing countries.  We will consider some of the dynamics that occur when impoverished people use forests in their daily lives. We will talk about the role of forests for medicines and wild foods, as sources of fuelwood and charcoal for energy, and other pressing topics that confront sustainable forest management such as the impacts of human health and diseases on forests. The course consists of modules on forests and livelihoods in developing countries, agroforestry, human health in forested environments, protected areas and their sustainability, small and medium forest enterprises (SMFEs), and  community forestry. Three cross-cutting themes (gender, tenure and forest rights, and climate change) will span all of the modules.

This course will engage you in developing a deeper understanding of the fundamental importance of forest resources in the lives and livelihoods of people in developing countries. Participants from tropical and developing countries may have lived much of what we will talk about in this course, and your experiences will deepen our understanding of the course material. Participants not from a developing country will gain a much better appreciation for the multitude of ways that people in developing countries use forest resources. Weekly videos will be complemented by readings, quizzes, and links to online resources to help you explore current scholarship in this domain. A discussion forum will enable you to delve more deeply into these issues with other participants and the course staff. The themes covered in this MOOC are important to anyone working in international forestry.

Have you ever imagined what is deep under the ground? What is happening deep inside the earth? How has the earth evolved into its present state? This course is an introduction to earth science, focusing on the deep earth. We will learn how temperature and chemical compositions inside the Earth are inferred from limited observations combined with laboratory experiments. We will also explore the fate of water on the early Earth related to advanced research questions. Upon finishing this course, you will learn how scientists interpret the unknown and use the scientific method to address immeasurable research challenges.

No specific knowledge is needed. Join this course and let’s imagine the inside of the Earth together.

Introduction to Environmental Science, ENVX, was first offered in early 2015.

Environmental science is the study of patterns and processes in the natural world and their modification by human activity.  To understand current environmental problems, we need to consider physical, biological and chemical processes that are often the basis of those problems. This course will give you the skills necessary to address the environmental issues we are facing today by examining scientific principles and the application of those principles to natural systems.  This course will survey some of the many environmental science topics at an introductory level, ultimately considering the sustainability of human activities on the planet.

Environmental impacts on Earth come from the number of people and the amount and types of resources that they use. By applying scientific principles and considering real-world examples, we will examine:

• The field of environmental science and how to think like an environmental scientist
• The human population and the ways in which changes in the population affect the environment
• Agriculture, soils and the environmental implications of eating meat, vegetables, local, organic, sustainable, industrial and other types of food
• Non-renewable fossil fuels with a focus on coal, petroleum and natural gas and the benefits and consequences of using each
• Renewable fuels such as wind and solar and identify that even renewable “green” energy sources have impacts as well as benefits
• Biodiversity and global change, which are the integrating units of environmental science

Education method
The course will utilize video lectures, interviews with experts, readings, discussions, multiple choice and prompted discussions and one graded quiz per week. There will also be several optional live office hours on Google Hangouts.

Completion of self-assessments, contributions to discussion and quiz scores will determine the final grade. 

Have you ever asked yourself what role land plays in front of demographic change, globalization or climate change?

Did you ever consider the connectivity between poverty and land access or changing land values? If you want to delve more deeply into these complex and fascinating issues, take part in our MOOC course, “Introduction Land Management.”

Land is a scarce and limited resource, which cannot be multiplied. It is a valuable basis for livelihood and for economic or ecological development. Land conflicts occur when people with differing interests run up against the declining availability of fertile land. Developing countries in general, and disadvantaged people in society are often the most affected groups. Yet, even industrialized countries face issues with sustainable land policy. As a result, experts in sustainable land management are desperately needed.

In this course, you’ll be introduced to the basics of land management. This MOOC gives you insight into basic functionalities and tasks of land management. It will help you recognize important land correlations with other fields of interest. You’ll understand contemporary global trends, necessary land related services, and the general process of executing land management interventions.

You learn why, when, and where sustainable land management is most needed and what the potential application fields of land management are. Exciting exercises, learning videos, discussions and literature recommendations accompany you through the course.

No previous knowledge of land management is required. 

Water is essential for life on Earth and of crucial importance for society. Water also plays a major role in affecting climate. Its natural cycle, from ocean to atmosphere by evaporation, then by precipitation back to land returning via rivers and aquifers to the oceans, has a decisive impact on regional and global climate patterns.

For students of engineering, climate science and environmental studies, this course offers a first introduction to the physics of water systems and their role in climate. In addition, we show you the state-of-the-art engineering interventions that can be applied to water systems. These can improve coastal safety and increase the availability of water supplies worldwide.

The course welcomes students from all over the globe, so we actively encourage discussion of water and climate issues you may experience in your location, now and in the coming decades.

After taking this course, you will be able to:

• Understand the different processes at play in the global water cycle.
• Identify and describe the flows of water and sand in different riverine, coastal and ocean systems.
• Identify mechanisms of climate change and explain the interplay between climate change, sea level, clouds, rainfall and future weather.
• Explain why, when and which engineering interventions are needed in rivers, coastal and urban environments.
• Explain why water for food and water for cities are the main challenges in water management and propose solutions.
• Explain and confront the challenges in better understanding and adapting to the impact of climate change on water over the coming 50 years.

The course consists of knowledge clips, movies, exercises, and exam assignments. There are opportunities to discuss course materials with your fellow students and the Course Team through our online forum. We also provide interactive feedback video sessions in which the lecturers discuss issues raised by students.
