  1. Information Requirements & Toolsfor Screening & Preliminary Assessment [SPEAKERS NAMES] [DATE]

  2. Review: Phase 1 of the EIA Process Phase I Phase II Understand proposed activity Why is the activity being proposed? What is being proposed? Screen the activity Based on the nature of the activity what level of environmental review is indicated? Conduct a Preliminary Assessment A rapid, simplified EIA study using simple tools(e.g. the USAID IEE) BEGIN FULL EIA STUDY SIGNIFICANT ADVERSE IMPACTS POSSIBLE ACTIVITY IS OF MODERATEOR UNKNOWNRISK SIGNIFICANT ADVERSE IMPACTS VERY UNLIKELY STOP the EIA process ACTIVITY IS LOW RISK (Of its nature, very unlikely to have significant adverse impacts) ACTIVITY IS HIGH RISK(Of its nature, likely to have significant adverse impacts) ENCAP EA-ESD Course: Information Requirements & Tools

  3. Limited focus Remember. . .! ! Therefore, we focuson the simpler tools and more limited information required by Phase 1. Screening and preliminary assessment are straightforward processes requiring only basic analysis! ENCAP EA-ESD Course: Information Requirements & Tools

  4. Relationship between information and tools What is a tool? YourCriticalJudgment Tools are simply ways of organizing and analyzinginformation.The outputs of a tool are only as good as the information that goes in. Tools don’t provide automatic answers. Your critical judgment is always required. Information Analysis Tool Identification and evaluation of impacts ENCAP EA-ESD Course: Information Requirements & Tools

  5. Types of information required Focus, please! • Screening & Preliminary Assessment requires threebasic types of information: Only the most basic biophysical and economic/social data is required for screening. Before you gather more detailed information, research likely impacts of the proposed activities. Focus information-gathering on these likely impacts! 1 2 Biophysical characteristics of site(s) Economic and social data 3 Maps ENCAP EA-ESD Course: Information Requirements & Tools

  6. Information requirements Biophysical characteristics of site(s) • climatic information • Soils, topography, watersheds • land use • habits/ecosystems • protected areas Economic and social data Maps ! Again, not all information is relevant to each activity. Focus your information-gathering on likely impacts! ENCAP EA-ESD Course: Information Requirements & Tools

  7. Information requirements Biophysical characteristics of site(s) • agricultural practices • water resources, sanitation • demographics • land ownership, community organization, other cultural aspects that affect resource use Economic and social data Economic and social data is usually required for activity design. (It is necessary to identify development needs & characterize beneficiaries) Therefore, your organization should already have much useful data.USE IT! Maps ENCAP EA-ESD Course: Information Requirements & Tools

  8. Information requirements Biophysical characteristics of site(s) • Maps (Topographic, land use, even sketch maps) • Plans and sketches of the proposed site and activity Economic and social data Why are maps essential for preliminary assessments? • Impacts are often significant because of location. E.g.: • are latrines near a water supply? • Is construction near a protected area? • Maps make these relationships clear. • Include maps in final documents Maps ENCAP EA-ESD Course: Information Requirements & Tools

  9. Where do I obtain information? 1 YOUR ORGANIZATIONTALK to staff who know the project, and know the sites. OBTAIN project documents and information Aren’t we forgetting something? ? What about reports by donor organizations and international agencies? What about government statistics? GIS databases? All these sources can be useful (and sometimes necessary) But good local information is the most important input to preliminary assessment. 2 DIRECT OBSERVATIONGo to the site(s)! 3 UTILIZE OTHERLOCAL TALENT & KNOWLEDGEcommunities, government, counterparts ENCAP EA-ESD Course: Information Requirements & Tools

  10. Why direct observation? • Environmental review should not be a desk exercise: You need to SEE You need to LISTEN • Are latrines close to water supplies? • Is there a drainage problem? • Visual inspection is the quickest and best way to check issues of location, scale and proximity that determine many impacts. Talk to men AND women. Women’s perceptions on environmental matters are critical and distinct. • Is there a land tenure problem? • How often does the river flood? • Stakeholders and local communities have local knowledge that you need. • And, impacts depend on what those affected value and need! ! ENCAP EA-ESD Course: Information Requirements & Tools

  11. Wait!What if I can’t travel to the sites? ! If at all possible, DON’Tmake the preliminary assessment a desk exercise. • But if you can’t visit the sites/area, you need: • MAPS and PHOTOS to help you visualize the environment. • to TALK to people who have been there ENCAP EA-ESD Course: Information Requirements & Tools

  12. Tools for Screening and Preliminary Assessments Cost-benefit analysis Multi-criteria analysis Risk assessment Simulation modeling Four basic tools: 1. Checklists 2. Matrices 3. Networks 4. Overlays When many people hear “EIA” they think of these tools. All are useful in full EIAs, but they are rarely used for preliminary assessments. . . Don’t panic! ENCAP EA-ESD Course: Information Requirements & Tools

  13. 1. Checklists Proposed Activities Clearing?  Cut/fill? -- Dredging?  Blasting? -- Checklists are simply lists of questions focused on “warning signs” of potential impacts & risks. Questions may concern. . . Nature of proposed activities Ecosystem functions present Spawning habitat?  Rearing habitat? -- • Checklist questions are: • Usually easily answered from field inspection & basic information about the activity. • Answered with yes/no (or simple quantitative) responses Topography& ecosystems Existing economic uses of water resource Drinking? -- Irrigation? -- Fishing?  Existing uses etc • Many sector-specific checklists exist ENCAP EA-ESD Course: Information Requirements & Tools After Sadar, 1994

  14. Checklists: Pros & Cons ! Advantages Flaws or omissions in the checklist often become flaws in your analysis. if an impact or issue is not on the checklist, it is usually forgotten  • Easy to apply for non-experts • Bring structure and consistency to: • gathering and classifying information • characterizing the basic nature of a project • identifying potential environmental impacts • designing mitigation measures • Help to assure that key impacts or issues are not forgotten Drawbacks Good tools for field survey! ENCAP EA-ESD Course: Information Requirements & Tools

  15. 2. Interaction Matrices What are they? They are tables containing. . . An interaction matrix matches each action to its associated impacts Aspects of the environment       +50%      After Sadar, 1994 Qualitative or quantitative estimates of how a particular actionaffects a particular aspect of the environment Proposed actions ENCAP EA-ESD Course: Information Requirements & Tools

  16. Matrices pros & cons Advantages !  • Does not characterize the baseline situation • Does not promote consideration of secondary impacts • Hard to show change over time • Filling in the matrix requires systematic consideration of the possible impacts of each action. • Because actions are matched to impacts, facilitates the identification of preventive mitigation measures • Summarizes a lot of information compactly & indicates the most significant impacts at a glance • Easily accommodates a mix of qualitative & quantitative impact estimates Drawbacks ENCAP EA-ESD Course: Information Requirements & Tools

  17. 3. Network Analyses A diagram of the cause and effect linkages by which proposed actions affect environmental quality and resources Key indicator of environmental quality – + Salmonoid populations Key economic use What do the signs mean? + cause and effect are directly related – cause and effect are inversely related – – + Fishing Spawning – + + – Temperature Flow Turbidity – – + Access Dredging Clearing Proposed actions After Sadar, 1994 ENCAP EA-ESD Course: Information Requirements & Tools

  18. Network Pros & Cons Advantages !  • An excellent tool for identifying indirect impacts • Provides a visual summary of cause and effect relationships that is easily understood & communicated to decision-makers • Identifies intervention points for mitigation measures that may not be obvious • Can be hard to show adequate level of detail • Static (cannot show change over time) • Does not show relative significance of impacts Drawbacks Networks show explicitly thecause and effect relationships that underlie a matrix ENCAP EA-ESD Course: Information Requirements & Tools

  19. 4. Map Overlays Need to develop an overlay example here Overlays are layered maps, in which each layer contains a particular type of information. Politicalboundaries Layers can be added or removed. Why? Land use GIS is increasingly used to produce overlays. But handmade overlays on transparent plastic work well! Topography (and more) ENCAP EA-ESD Course: Information Requirements & Tools

  20. Overlays: Pros & Cons Advantages !  • The significance of impacts often depends on location.Overlays make critical issues of location clear. • Maps are well-understood (good for communication to reviewers and to local communities) • Maps are a basic part of information gathering for EIA.You already have a map. Use it to help you analyze impacts • Unable to show timing, reversibility, and probability of impacts • Sharp boundary definitions can be misleading Excellent for assessing alternative routes forpipelines, roads, powerlines Drawbacks ENCAP EA-ESD Course: Information Requirements & Tools

  21. Appropriateness: will the tool produce the needed output? Cost, time & effortRemember, EA is generally <1% of project capital costs Choosing tools Two key criteria for selecting tools & 1 2 In general,sophisticated and resource-intensive methods are not the most appropriate in practice !
