Edition 1.0 · 2026-10-15

Tamil Nadu, Kerala, Karnataka, Andhra Pradesh, Telangana, Puducherry and Lakshadweep. Neighbouring Western Ghats research is background only.

Curated evidence map, not an exhaustive review of all studies. Searches used government and original research organisations, research-team summaries and practitioner records. Review depth is stated per source. Search snippets and catalogues are explicitly distinguished from report excerpts. No full-text appraisal is claimed where access failed.

Responses, measures and suggested roles below are POIGAI planning synthesis, not verified local project designs. No confirmed partners, budgets or delivery dates are implied. Before funding: location, baseline, unmet need, implementation partner, maintenance owner, costed design and measurable outcome.

## K01 — Reliable village water

கிராம நீர் பாதுகாப்பு

**Where:** Ramanathapuram; southern Tamil Nadu screening areas

**States / UTs:** Tamil Nadu

**Evidence:** Groundwater resource and quality assessments are distinct evidence streams [S11]. Regional evidence cannot establish a particular village’s unmet need.

**Response to assess:** Assess demand, leakage, storage and source quality first; compare repairs, safe rainwater capture and hydrogeologically suitable recharge. Reject recharge where contamination or saline conditions make it unsafe.

**Baseline:** Seasonal supply days, source tests, household collection time, extraction and recharge context.

**Measures:** Reliable supply days; tested water quality; collection time; operating cost.

**Roles to appoint:** Panchayat or utility with an explicitly appointed maintenance operator.

**Gap:** Exact village, household baseline, aquifer suitability and lifecycle budget unverified.

**Sources:** S11

## K02 — Groundwater depletion in hard-rock catchments

நிலத்தடி நீர்

**Where:** Interior Karnataka; Telangana plateau; Rayalaseema

**States / UTs:** Karnataka, Telangana, Andhra Pradesh

**Evidence:** CGWB’s Karnataka assessment provides resource screening [S10]; Telangana’s state plan supplies sector context [S07]. Neither is a well-yield guarantee.

**Response to assess:** Build a community water budget; meter large abstractions; align crops with dependable supply; assess managed recharge with a hydrogeologist and downstream users.

**Baseline:** Seasonal water levels, abstraction, well failures and water quality.

**Measures:** Water-level trend over comparable seasons; extraction; irrigation water per unit output.

**Roles to appoint:** Groundwater department, panchayat and participating water users.

**Gap:** Assessment-unit tables and present village surveys still needed.

**Sources:** S10, S07

## K03 — Urban lakes and sewage inflows

ஏரிகள் மற்றும் கழிவுநீர்

**Where:** Bengaluru lake catchments; Jakkur as a documented case

**States / UTs:** Karnataka

**Evidence:** Jakkur’s practitioner account describes treated and untreated inflows, vegetation work and multiple maintenance institutions [S20].

**Response to assess:** Trace every inlet; intercept pollution; verify treatment compliance; evaluate wetlands as polishing stages with ongoing maintenance, rather than substitutes for sewage treatment.

**Baseline:** Inlet flows and pollutant loads; seasonal lake chemistry; treatment uptime.

**Measures:** Compliant inflows; oxygen and nutrient trends; recurring maintenance completed.

**Roles to appoint:** Utility, lake custodian and contracted operator, with community oversight.

**Gap:** 2018 case observations are not current lake measurements or a causal impact trial.

**Sources:** S20, S19

## K04 — Flood pathways and wetland storage

வெள்ளத் தாங்குதிறன்

**Where:** Chennai basin; Hyderabad; Bengaluru; Puducherry urban catchments

**States / UTs:** Tamil Nadu, Telangana, Karnataka, Puducherry

**Evidence:** Flood studies require rainfall, drainage, land-use and exposure evidence together. The Chennai event summary cautions against treating flood damage as rainfall attribution [S15].

**Response to assess:** Map drainage and flood storage at catchment scale; protect water pathways; assess retention areas, maintenance and accessible evacuation routes. Check whether interventions shift flooding downstream.

**Baseline:** Drain connectivity, observed inundation depth and duration, vulnerable assets and rainfall.

**Measures:** Inundation duration under comparable storms; protected routes; warning reach.

**Roles to appoint:** Urban local body, drainage authority and disaster-management teams.

**Gap:** Hydraulic modelling and local consent needed before earthworks.

**Sources:** S15, S16, S08

## K05 — Landslide exposure in the Western Ghats

மலைச்சரிவு அபாயம்

**Where:** Wayanad; Nilgiris; Kodagu as separate screening landscapes

**States / UTs:** Kerala, Tamil Nadu, Karnataka

**Evidence:** The 2024 Wayanad assessment found intensified triggering rain with substantial modelling uncertainty [S14]. It does not establish the cause of every slope failure.

**Response to assess:** Use official susceptibility maps, geotechnical inspection and local rainfall thresholds; prioritise evacuation access and exposure reduction. Retaining structures need engineered designs.

**Baseline:** Slope geology, past failures, drainage, rainfall and households in runout paths.

**Measures:** Warning-to-action time; evacuation drills; people and assets removed from high exposure.

**Roles to appoint:** District disaster authority, qualified geotechnical team and local government.

**Gap:** Transfer from Wayanad to other slopes requires independent validation.

**Sources:** S14

## K06 — Hot classrooms and public buildings

வெப்பத்திலிருந்து பாதுகாப்பு

**Where:** Tiruchirappalli concept; hot urban and peri-urban institutions

**States / UTs:** Tamil Nadu, Telangana, Karnataka, Andhra Pradesh, Kerala, Puducherry

**Evidence:** Telangana’s cool-roof policy defines material-performance provisions [S09]; it is policy evidence, not measured results for a particular school.

**Response to assess:** Compare reflective roofs, external shade, safe ventilation and efficient cooling. Inspect waterproofing, structure, glare, maintenance and indoor air quality before retrofit.

**Baseline:** Paired indoor/outdoor temperature and humidity logs; occupancy; roof condition; electricity.

**Measures:** Occupied hours above an agreed comfort threshold; comparable indoor temperature; kWh.

**Where:** Construction sites, markets, farms and transport hubs

**States / UTs:** Tamil Nadu, Telangana, Andhra Pradesh, Karnataka, Kerala, Puducherry

**Evidence:** State climate plans address health and livelihoods [S06, S07]. Air temperature alone does not capture all occupational exposure.

**Response to assess:** Have occupational-health professionals design shade, rest, safe drinking-water access and warning procedures. Adapt work schedules with workers, protect wages and provide an emergency response protocol.

**Baseline:** Task and exposure mapping; humidity and radiant heat; access to shade and water.

**Measures:** Protected work periods; warning coverage; recorded heat incidents with reporting quality checked.

**Roles to appoint:** Employer and local authority with worker representatives and health teams.

**Gap:** No medical threshold or clinical advice is inferred from this bank.

**Sources:** S06, S07

## K08 — Shoreline erosion and coastal livelihoods

கடலோர அரிப்பு

**Where:** Coromandel and Malabar coasts; Puducherry and Karaikal

**States / UTs:** Tamil Nadu, Kerala, Karnataka, Andhra Pradesh, Puducherry

**Evidence:** NCCR’s official summary reports shoreline change from both human and natural drivers [S17]. Historic erosion rates do not forecast an individual property’s future.

**Response to assess:** Commission sediment-cell and hazard assessment; compare setbacks, dune recovery, relocation support and engineered protection. Evaluate neighbouring-shore impacts and fishing access.

**Baseline:** Shoreline positions, seasonal beach profiles, structures, access and land tenure.

**Measures:** Beach-profile trend; maintained livelihood access; exposure avoided.

**Roles to appoint:** Coastal authority and local government with fishing communities.

**Gap:** Permits, sediment budget and long-term maintenance must be resolved.

**Where:** Krishna and Godavari deltas; coastal Tamil Nadu; Yanam and Karaikal

**States / UTs:** Andhra Pradesh, Tamil Nadu, Puducherry

**Evidence:** State profiles identify differing cyclone, surge and river settings [S06, S08]. Hazard combinations vary by location.

**Response to assess:** Map compound river–rain–surge exposure; strengthen last-mile warning, inclusive shelters and resilient essential services. Validate any ecosystem buffer against local habitat and hydrology.

**Baseline:** Elevation, evacuation travel time, warning reach, essential-service exposure.

**Measures:** Accessible shelter coverage; drill completion; service restoration time.

**Roles to appoint:** District disaster authority, local government and utility owners.

**Gap:** Current official hazard maps and facility audits needed.

**Sources:** S06, S08

## K10 — Reefs and marine heatwaves

பவளப்பாறை பாதுகாப்பு

**Where:** Lakshadweep; Gulf of Mannar for separate monitoring

**States / UTs:** Lakshadweep, Tamil Nadu

**Evidence:** The official 2024 response records Lakshadweep bleaching and INCOIS monitoring services [S24, S25]. This is not a current Gulf of Mannar condition report.

**Response to assess:** Use dated bleaching alerts and ecological surveys; reduce local sewage, anchor and extraction damage; agree community-led response. Restoration cannot remove ocean warming.

**Baseline:** Reef-cover transects, temperature stress, local pressures and fishing dependence.

**Measures:** Live coral and recruitment trends; reduced damaging activity; livelihood resilience.

**Roles to appoint:** Relevant reef and fisheries authorities with island or coastal communities.

**Gap:** Reef-specific condition and recovery evidence needed before restoration claims.

**Sources:** S24, S25

**Sources:** S12, S13

## K12 — Natural farming: test benefits and trade-offs

இயற்கை விவசாய மதிப்பீடு

**Where:** Crop-specific farmer trials in Andhra Pradesh and Karnataka

**States / UTs:** Andhra Pradesh, Karnataka

**Evidence:** ICAR’s survey and sample study reports differing experiences between crops and states [S21]. Farmer perception and adopter comparisons do not establish universal causal benefits.

**Response to assess:** Use comparable plots and whole-farm records to evaluate input reduction, nutrient balance, pest management and transition labour. Preserve farmer choice and avoid guaranteed yield or income claims.

**Baseline:** Crop and soil comparability; prior yield; purchased and household inputs; labour.

**Measures:** Net return including labour; yield variability; soil indicators; adoption retention.

**Roles to appoint:** Participating farmers, independent agronomist and evaluation team.

**Gap:** Selection bias, market premiums and long-term nutrient balance need explicit treatment.

**Sources:** S21

## K13 — Farm ponds and watershed interventions

நீர்ப்பிடிப்பு மேலாண்மை

**Where:** Semi-arid catchments; location selected after hydrology

**States / UTs:** Andhra Pradesh, Telangana, Karnataka, Tamil Nadu

**Evidence:** ICAR-CRIDA lists farm-pond design guidance [S13]. A catalogue listing does not prove a pond is suitable or beneficial at every farm.

**Response to assess:** Assess catchment water balance, soils, safety, evaporation and downstream rights; compare in-situ conservation with storage and supplemental irrigation.

**Baseline:** Runoff, seasonal demand, soils, evaporation and downstream users.

**Measures:** Supplemental water delivered; crop benefit; maintenance; downstream effects.

**Roles to appoint:** Farmer group and watershed institution with engineering support.

**Gap:** No storage volume or construction budget should be set before survey.

**Sources:** S13, S18

## K14 — Land degradation and soil loss

**Where:** Erosion-prone slopes and degraded cultivated catchments

**States / UTs:** Tamil Nadu, Andhra Pradesh, Telangana, Karnataka, Kerala

**Evidence:** SAC–ISRO provides land-degradation mapping and change-analysis resources [S18]. Remote-sensing categories need ground verification.

**Response to assess:** Identify the degradation process first; assess contour measures, ground cover and appropriate grazing or cultivation changes. Protect drainage and land-user rights.

**Baseline:** Erosion features, soil depth, cover, infiltration and land-use history.

**Measures:** Ground cover; soil loss proxy; infiltration; productive use maintained.

**Roles to appoint:** Land users and watershed authority with soil-conservation specialists.

**Gap:** Field diagnosis needed; a degraded-land label is not permission for plantation.

**Sources:** S18

## K15 — Native habitats and invasive plants

உள்ளூர் உயிரினங்கள் பாதுகாப்பு

**Where:** Nilgiris and other Western Ghats landscapes

**States / UTs:** Tamil Nadu, Kerala, Karnataka

**Evidence:** ATREE documents landscape-specific restoration and invasive-species research [S22]. Intervention success depends on habitat, disturbance and follow-up.

**Response to assess:** Map native habitat and invasion; pilot species-appropriate removal with native recovery, erosion control and repeat monitoring. Budget follow-up before scaling.

**Baseline:** Native species, invasive cover, regeneration and community resource use.

**Measures:** Native recovery; invasive rebound; habitat function and livelihood effects.

**Baseline:** Dated local measurements, affected groups, existing services and counterfactual.

**Measures:** Outcome against baseline; distribution of benefits; full costs and maintenance.

**Roles to appoint:** Named project proponent and independent reviewer; appointments require acceptance.

**Gap:** No intervention here is a validated or funded POIGAI project.

**Sources:** S02, S05

## K22 — Choose evidence at the right scale

சரியான அளவில் ஆதாரம்

**Where:** Regional assessment → district screening → site design

**States / UTs:** Tamil Nadu, Kerala, Karnataka, Andhra Pradesh, Telangana, Puducherry, Lakshadweep

**Evidence:** MoES synthesises observed and projected regional climate [S01]. Scenario outputs, weather forecasts and measured local conditions answer different questions.

**Response to assess:** Keep observation periods, scenarios, model resolution and uncertainty visible. Use multiple relevant datasets and technical review; investigate disagreements rather than averaging incompatible risk indices.

**Baseline:** Source year, geography, methods, scenario and data quality.

**Measures:** Traceable claims; reproducible baselines; documented uncertainty and correction history.

**Roles to appoint:** Knowledge editor and relevant subject specialist.

**Gap:** This edition screens selected sources and does not claim an exhaustive systematic review.
