Organic waste is everywhere. Farms produce livestock manure and crop residues, food businesses generate food scraps, and rural households create biodegradable waste every day. When these materials are poorly managed, they can become a source of pollution, odors, and greenhouse gas emissions. But organic waste can also be a resource. Through organic waste to energy systems, biodegradable materials can be processed to recover energy in the form of biogas. The same process can a

Environmental issues can feel overwhelming when we only learn about them through textbooks. Climate change, waste, pollution, and biodiversity can seem like big global problems that are far removed from everyday life. But environmental education can start much closer to home. Students can learn about sustainability by observing their surroundings, understanding where their waste goes, growing food, measuring water use, or taking part in local environmental projects. These exp

Sustainability is a field that connects environmental science, social systems, economics, technology, and everyday life. Because of this, some of the most valuable lessons cannot be learned from textbooks alone. Students need opportunities to see how environmental challenges affect real communities, how resources are used, and how sustainability solutions work in practice. This is where field research for sustainability students becomes important. Field research allows studen

A circular economy doesn't have to start with a large recycling facility or a high-tech system. In rural communities, it can start with something much simpler: making better use of what is already available. For many villages in Indonesia, that could mean turning food waste into compost, livestock manure into biogas, or agricultural waste into useful resources instead of throwing it away. This is the idea behind circular economy in rural communities, keeping resources in use,

Forest and land fires are not only a problem during the dry season. The risk can become much higher when landscapes have been degraded, forests have been cleared, and natural water systems have been disrupted. This is why ecosystem restoration in Indonesia is about more than planting trees. Healthy forests, peatlands, wetlands, and agricultural landscapes can help regulate water, protect soil, support biodiversity, and provide resources for local communities. Restoring these

Energy is rarely used in isolation. Producing electricity can require water, agriculture depends on energy for irrigation and processing, and treating and distributing water requires energy. These connections mean that a change in one resource system can create consequences for others. This is the idea behind the energy nexus. The concept becomes particularly relevant when looking at the relationship between energy, water, and food. Often referred to as the water-energy-food

Indonesia is highly exposed to the effects of climate change. As an archipelagic country with thousands of islands, extensive coastlines, tropical ecosystems, and large agricultural areas, climate-related changes can affect communities and livelihoods in many different ways. Climate vulnerability in Indonesia is shaped by more than exposure to climate hazards. It also depends on how prepared communities are, how much infrastructure is available, and how dependent local liveli

Agriculture depends heavily on natural systems. Farmers need reliable water, healthy soil, suitable temperatures, and predictable growing conditions to produce food and commodities. As climate change affects rainfall patterns, temperatures, extreme weather, and water availability, agricultural producers face increasing challenges in maintaining productivity. This is where climate-smart agriculture and commodities can play an important role. Climate-smart agriculture focuses o

Sustainable development in Indonesia involves more than economic growth. The country also needs to address poverty, access to education and healthcare, environmental protection, climate change, employment, energy, food security, and inequality. These challenges are closely connected. Progress in one area can influence outcomes in another. Expanding renewable energy, for example, can support climate action while also improving energy access and creating economic opportunities.

Recycling can help reduce waste and keep useful materials in circulation, but putting something into a recycling bin does not automatically mean it will be recycled. Different recycling facilities accept different materials, and items often need to be sorted and prepared correctly before collection. Food residue, liquids, mixed materials, and incorrect items can contaminate an otherwise recyclable batch and make processing more difficult. Understanding which materials can be

Solar panels do not install themselves. Electric vehicles still need mechanics. Waste cannot become a resource without workers who know how to collect, separate and process it. Even the strongest green policies will struggle to deliver results without people who have the right skills and access to decent employment. This is why green job creation matters. The Green Economy Tracker notes that green jobs can provide sustainable livelihoods for citizens. Green jobs are defined a

A green economy is often explained through complex words: decarbonisation, circular economy, green finance, renewable energy, and net-zero targets. But behind every policy is a human question. Who gets the new jobs? Who loses old ones? Who has access to training? Who can adapt, and who is left behind? For Vietnam and Southeast Asia, this question is becoming increasingly important. Countries across the region are setting green growth, climate, and energy goals. But ambition a

Vietnam’s renewable energy ambition is entering a more demanding phase. The Revised Power Development Plan VIII, approved under Decision 768/QD-TTg on 15 April 2025, targets renewable energy sources excluding hydropower to reach 28–36% by 2030, while planning offshore wind capacity of 6,000–17,032 MW to become operational between 2030 and 2035. These figures show ambition. But behind every renewable energy target is a practical question: who will plan, build, operate, mainta

The language of the green economy is now firmly embedded in public policy. Governments are setting climate targets, expanding renewable energy, and introducing green finance and circular economy policies. Across Southeast Asia, these ideas are no longer niche. They are becoming part of how countries discuss competitiveness, investment, jobs, and long-term development. The challenge is no longer whether governments are talking about the green economy, but whether those ambitio

Southeast Asia is growing rapidly. Cities are expanding, energy demand is rising, industries are changing, and governments are setting new climate and sustainability targets. But as the region moves toward greener growth, one question becomes more important: How can we determine if the goals of a green economy are being translated into actual policy actions? This question is not easy to answer. Green economy progress cannot be measured only by indicators or figures related to

Many of the products and materials people use every day follow a simple pattern: resources are taken from nature, turned into products, used, and eventually thrown away. This is known as a linear economy. A circular economy takes a different approach. Instead of treating materials as something that becomes waste after use, it aims to keep products, materials, and resources in use for as long as possible. Understanding what is circular economy and example can help explain how

Climate change is creating challenges that affect energy systems, agriculture, water resources, businesses, and communities. At the same time, new technologies are creating practical ways to reduce emissions, use resources more efficiently, and help communities adapt to changing environmental conditions. Climate tech and innovation refers to technologies, products, and solutions designed to address climate change. These can include renewable energy systems, low-carbon technol

Sustainability is no longer limited to large environmental projects or major changes in how products are made. Businesses can also apply sustainability principles through everyday decisions, from how offices use energy and manage waste to how employees travel, purchase supplies, and work with local communities. Sustainability in business and workplace means considering the environmental, social, and economic impact of business activities and finding practical ways to reduce n

Biogas and biomass are both connected to renewable energy, but they are not the same thing. The terms are sometimes used interchangeably, especially when discussing agricultural waste, organic materials, and clean energy. However, biomass refers to the organic material itself, while biogas is one type of energy that can be produced from certain organic materials. Understanding the difference between biogas and biomass makes it easier to see how agricultural waste, food waste,

Renewable energy is often discussed as if one technology can meet every energy need. In reality, different renewable energy technologies have different costs, performance levels, resource requirements, and applications. Solar, wind, hydropower, geothermal, and biogas can all contribute to a cleaner energy system, but the most suitable option depends on factors such as location, available resources, energy demand, and how consistently electricity needs to be produced.
