	The clue to good informed decisions lies in the term itself - "informed" decisions. How do we ensure that the right information, is delivered to the right decision-maker at the right level of action (and at the right time), so that the necessary decisions are taken. What indeed are these decisions? Environmental decision-making is fundamentally an information-intensive process. Decisions related to climate change, biodiversity conservation, water management, urban development, or pollution control require not only scientific and technical data, but also social, economic, institutional, and local knowledge. The quality of decisions depends less on the volume of information available and more on how relevant information is identified, interpreted, communicated, and ultimately used. In many environmental contexts, decision-makers face uncertainty, competing interests, and incomplete data. Information may be fragmented across institutions, expressed in highly technical forms, or disconnected from the realities faced by communities on the ground. As a result, well-intentioned policies and projects can fail to achieve desired outcomes if information is poorly framed or inadequately integrated into the decision process. Figure 1: The Decision-Making Cycle This document outlines a practical framework for Information for Environmental Decision-Making, focusing on how information supports each stage of the decision cycle. It emphasizes problem definition, information identification, analysis, decision selection, and follow-up through implementation and monitoring. The framework is applicable across scales, from local community initiatives to national policy formulation, and is relevant to governments, businesses, civil society organizations, researchers, and students engaged in environmental governance and sustainability planning. 1. Defining the problem Take time to properly define the problem. What is the issue to be covered? What is the problem? What decisions need to be taken? A fish-bone diagram will sometimes help in understanding the complex interlinkages that create a particular 'problem'. For each of the causes or its effects, make a list of information or data that will be required, and clarify how that information will lead to a better decision. Figure 2: The Fiskbone Diagram Good environmental decisions therefore begin with a clear, shared understanding of what the problem really is. A well-defined problem sets the direction for what information is needed and what decisions must follow. Key Steps Articulate the environmental issue precisely Identify its causes, consequences, and boundaries Map drivers, actors, and stakeholders affected Why It Matters Environmental problems are often complex and interconnected. For example, poor urban air quality may stem from vehicle emissions, industrial activities, and household cooking fuels. Identifying these layers prevents superficial solutions that only treat symptoms. Tool Example Fishbone Diagram (illustrated above) Use this to break a problem down into root causes and contributing factors. For instance: Problem: Elevated fine particulate matter (PM2.5) in City X Causes: Transport emissions | Industrial boilers | Construction dust | Open burning Contributing factors: lack of public transit, weak monitoring systems, seasonal weather patterns This visualization helps planners see where to focus further information gathering and action. Remember that sometimes, the real cause can lie hidden behind the 'visible' causes.
	2. Finding the information Determine the sources from where information needed for decision-making can be obtained. What information needs to be taken? Who has that information? Why is that information being collected by the source? Which component of the problem at hand will it help? Evaluate the sources to see which of them can provide the best information, and identify the mode and format in which the information is presented. Keep in mind that different sources provide information in different formats (for different reasons!). Figure 3: The Information Pyramid Information you know you have Information you know you don't have Information you don't know you have Information you don't know you don't have Four states of information possession So, once the problem is defined, decision-makers need relevant and reliable information to assess it. This step answers questions like Who has the data? What kind of data is required? How will it be used? Types of Information Scientific data - air quality measurements, biodiversity surveys Socio-economic data - population exposure, health statistics Policy and legal information - environmental standards, regulations Community insights - lived experiences, traditional ecological knowledge Example in Practice For a river restoration project, you would gather: Water quality data (pH, nutrients, turbidity) Land-use maps and sewage discharge records Feedback from local fishing communities about seasonal fish catches This combination of quantitative data and qualitative insights leads to better decisions than relying on one source alone. Remember that information can also lie in experiences and insights that are not 'recorded.' Also look at the information pyramid to see if all levels are covered ...
	3. Processing the Knowledge This where the information gathered is matched with the problem in hand. The relevant information from each source is extracted and information from multiple sources is organized. Which parts of the information collected needs to be used? What additional data or information is needed? How can information be best presented to be able to understand the situation and take decisions? The collected information is evaluated and integrated for its relevance, validity and interconnectedness. Figure 4: Information Needs for Decision-Making Gathering data is thus only half the job. Decision-makers must process, analyze, and integrate information to make it meaningful and actionable. Core Activities Evaluate relevance and validity of data Organize multiple sources for coherence Visualize information (charts, GIS maps, trend lines) Presentation Matters Presenting information effectively influences decisions. A clear chart showing rising emissions over time or a spatial map of flood risk zones can be far more persuasive than raw tables of numbers. Example In climate adaptation planning, combining temperature rise projections with vulnerable population maps helps local governments prioritize areas for cooling centers or green infrastructure. Remember that it is critical to package the information to fit the audience using the right medium: presenting the right information at the right time to the right audience.
	4. Taking the decision In an interactive and inclusive process involving all the concerned parties, form an opinion from the information collected for its effectiveness and efficiency. Use it to take the decision. Has the decision taken help in solving the problem at hand? Was the decision satisfactory and took into account all the views of concerned parties? A decision taken may need to be examined closely and refined, and modified to meet differing needs over time. Figure 5: The Problem-Decision cycle Decision-making is therefore inherently about choosing among alternatives based on processed information. It should be participatory, transparent, and adaptive. Principles Involve relevant stakeholders ? governments, communities, businesses Weigh costs, benefits, and risks of each option Be explicit about uncertainties and assumptions Real-World Example When deciding where to build a new wind farm, planners might compare: Option A: Coastal site with strong winds but high tourism value Option B: Inland site with moderate winds but low economic disruption By consulting local residents, environmental groups, and industry, the final decision can balance energy goals with social and ecological priorities. Remember that implementing the decision (actors and actions), as well as monitoring and evaluating the actions taken, are integral parts of the decision! 5. Implementing, Monitoring, and Evaluating Decisions don�ft end at choice. Real environmental change requires implementation plans, monitoring systems, and periodic evaluation to track outcomes and make course corrections. Example A city adopts a new recycling policy. Implementation includes: Public education campaigns Recycling bins in all neighborhoods Monthly reporting of recycling rates If data shows low participation in certain districts, authorities can adjust outreach or services to improve results. Anchoring Decisions in Frameworks and Agreements Environmental decisions do not take place in isolation. They are increasingly shaped by international frameworks, national policies, and shared normative goals that provide direction, legitimacy, and accountability. Anchoring environmental decision-making within such frameworks helps ensure that individual projects and policies contribute to broader sustainability objectives rather than addressing problems in a fragmented or short-term manner. One of the most influential global reference points for environmental decision-making is the 2030 Agenda for Sustainable Development and its Sustainable Development Goals (SDGs). The SDGs offer an integrated set of social, environmental, and economic objectives that are particularly useful for framing environmental decisions in a holistic way. For example, decisions related to energy planning are not only linked to climate action under SDG13, but also to affordable and clean energy under SDG7, health under SDG3, and sustainable cities under SDG11. By mapping decisions and indicators to relevant SDGs, decision-makers can better understand synergies, manage trade-offs, and communicate the broader value of environmental actions to stakeholders. In addition to the SDGs, multilateral environmental agreements (MEAs) provide legally and politically significant anchors for decision-making, particularly at national and sectoral levels. Agreements such as the Paris Agreement on climate change, the Convention on Biological Diversity, and the Basel Convention on hazardous waste management establish shared commitments, targets, and reporting obligations for countries. These agreements influence national laws, regulatory standards, and investment priorities, and therefore shape the context in which environmental decisions are made. For instance, a government designing a national waste management strategy must consider international obligations related to transboundary movement of hazardous waste, while businesses operating across borders increasingly align their environmental practices with MEA principles to manage risk and maintain credibility. Together, global frameworks and international agreements provide a common language and reference point for environmental decision-making. They help align local actions with global goals, support policy coherence across sectors, and strengthen accountability by linking decisions to agreed principles and long-term commitments. To ensure decisions are aligned with broader sustainability goals, it helps to link them to global and national frameworks. Sustainable Development Goals (SDGs) The SDGs provide common objectives that inform environmental priorities. For instance: SDG13 (Climate Action) motivates national plans to reduce greenhouse gases SDG6 (Clean Water and Sanitation) guides urban water recycling projects SDG12 (Responsible Consumption and Production) frames corporate waste reduction strategies Multilateral Environmental Agreements (MEAs) MEAs influence decision-making by setting international standards and commitments. Examples include: The Paris Agreement for climate mitigation The Convention on Biological Diversity for ecosystem preservation The Basel Convention on hazardous waste control Example: A manufacturing firm updates its waste management policies to comply with Basel Convention disposal protocols. Decision Support Tools and Approaches Given the complexity and uncertainty inherent in environmental problems, decision-makers increasingly rely on structured tools and approaches to support analysis, deliberation, and choice. These tools do not replace judgement, but rather enhance the capacity of individuals and institutions to understand complex systems, compare alternatives, and engage stakeholders in informed discussions. One widely used approach is systems thinking, which emphasizes the interconnected nature of environmental, social, and economic processes. Rather than treating problems in isolation, systems thinking encourages decision-makers to examine feedback loops, time delays, and unintended consequences. For example, land-use decisions in urban areas can affect water runoff, energy demand, air quality, and social equity simultaneously. By using systems maps or causal loop diagrams, decision-makers can better anticipate secondary impacts and design interventions that are more robust over time. Participatory decision-making is another critical approach, particularly in environmental contexts where decisions affect multiple stakeholders with differing interests and knowledge. Engaging communities, civil society organizations, businesses, and technical experts throughout the decision process improves the relevance and legitimacy of decisions. Participation also brings local and experiential knowledge into the process, which is often missing from purely technical analyses. For instance, community consultations in flood-prone areas can reveal historical patterns, coping strategies, and social vulnerabilities that are not captured in hydrological models alone. In situations where multiple objectives must be balanced, multi-criteria decision analysis (MCDA) offers a structured way to compare options using diverse criteria such as environmental impact, cost, social acceptability, and institutional feasibility. MCDA makes trade-offs explicit and transparent, helping decision-makers justify choices in complex and sometimes contested contexts. This approach is commonly used in infrastructure planning, energy policy, and resource management, where no single option clearly dominates across all criteria. Taken together, these decision support tools and approaches help bridge the gap between information and action. They provide practical ways to manage complexity, incorporate multiple perspectives, and make informed choices under uncertainty, thereby strengthening the overall quality and resilience of environmental decision-making. To make decisions more robust and nuanced, environmental practitioners use analytical and creative approaches: Systems Thinking Examines feedback loops and interdependencies among environmental, social, and economic factors. Example: Modeling how land use changes affect watershed health over time. Participatory Decision-Making Engages stakeholders early and continuously to ensure legitimacy and equity. Example: Community mapping workshops for urban green space planning. Multi-Criteria Decision Analysis (MCDA) Evaluates options based on multiple criteria such as cost, environmental impact, and social equity. Example: Choosing a public transit expansion plan that scores high on emissions reduction and accessibility. Implications Effective environmental decision-making is not a one-time event but a continuous and adaptive process. Information plays a central role throughout this cycle, shaping how problems are understood, which options are considered, and how outcomes are evaluated. When information is relevant, credible, and accessible, it enhances transparency, builds trust among stakeholders, and improves the likelihood of sustainable outcomes. At the same time, information alone does not guarantee good decisions. Values, power relations, institutional capacities, and stakeholder participation strongly influence how information is interpreted and acted upon. Recognizing these dimensions is essential, particularly in complex environmental issues where trade-offs are unavoidable and uncertainty is high. By systematically linking information to decision stages and by situating decisions within broader sustainability frameworks such as the Sustainable Development Goals and multilateral environmental agreements, this approach helps bridge the gap between knowledge and action. Ultimately, strengthening information for decision-making contributes to more informed, inclusive, and resilient environmental policies and practices, supporting long-term sustainability at local, national, and global levels.
