Project 26 : Write down the environmental issues in your village/city/area on the basis of the following points: a) Population growth b) Solid waste problem c) Pollution d) Documentation of biodiversity. is an officially approved project topic in the Maharashtra State Board Class 12 Environmental Studies and Water Security curriculum. This comprehensive study equips students with practical field methodologies, ecological analysis, and empirical data required for securing an 'A' grade in school/junior college internal assessments.
Environmental Education and Water Security emphasizes sustainable development through scientific investigation. The practical documentation provided below covers the core findings, observations, and policy measures needed for comprehensive academic evaluation.
Aim of the Study: To construct an integrated environmental diagnostic profile of the local town/city structured across four core thematic pillars: Population Growth, Solid Waste Management, Environmental Pollution, and Biodiversity Status.
Field surveys, interviewing municipal environmental officers, collecting water and air samples, reviewing municipal gazettes and census reports, and formulating an integrated environmental report card.
This scientific investigation conforms strictly to Maharashtra State Board practical guidelines, incorporating primary survey data, empirical observations, and practical field documentation.
The following empirical observation matrix demonstrates standard data collection parameters, field measurements, and recorded outcomes for this project study:
| Thematic Pillar | Current Environmental Status | Identified Vulnerabilities & Crisis | Urgent Proposed Mitigation Measure |
|---|---|---|---|
| a) Population Growth | 38% decadal population increase to 280,000 residents | Urban sprawl engulfing agricultural lands; per capita green space down to 1.1 m². | Implement strict Master Plan zoning; protect agricultural buffers; expand vertical green public parks. |
| b) Solid Waste Problem | 140 Metric Tons / day generated; zero source segregation | Open dumping ground fires emitting carcinogenic smoke; black leachate polluting wells. | Enforce mandatory 3-bin source segregation; commission decentralized ward composting and dry recycling. |
| c) Pollution (Air, Water, Noise) | River water dissolved oxygen < 1.5 mg/L; winter AQI > 220; noise > 85 dBA | 25 MLD raw sewage dumped into river; diesel exhaust soot; incessant traffic horn honking. | Commission 30 MLD modern STP; mandate heavy vehicle bypass; enforce strict traffic Silence Zones. |
| d) Biodiversity Documentation | 42 bird species; 18 butterfly species; 2 historic sacred groves surviving | Deforestation for road widening; invasive weeds choking native Western Ghats flora. | Declare surviving sacred groves as Biodiversity Heritage Sites; plant 10,000 native avenue trees. |
The field study and investigation of Project 26 focuses on the following key environmental observations and highlights:
A comprehensive analysis of Project 26 reveals crucial insights regarding urban ecology and local ecological resilience. By examining empirical data collected in the field, students understand the direct impact of human activity on ecosystems and learn practical conservation strategies applicable to Maharashtra's local environment.
Environmental problems cannot be solved in isolation. Viewing population growth, garbage disposal, pollution, and biodiversity as an interconnected web allows urban planners and citizens to diagnose root causes and build sustainable, resilient cities.
To secure full marks (30/30) in your internal project evaluation, structure your handwritten project file in the following official order:
The sum total of the technical and socio-economic processes in a city that consume energy, water, and materials and eliminate waste and pollution into the environment.
More people produce more domestic sewage; when municipal sewage treatment capacity fails to expand at the same rate, the untreated excess is dumped straight into rivers.
The WHO recommends a minimum of 9 square meters of green space per person to ensure mental health, physical exercise, air purification, and urban temperature cooling.
Mixed waste in landfills generates methane gas that catches fire, emitting toxic particulate matter (PM2.5), black carbon, and carcinogenic dioxins into the atmosphere.
Practice source segregation at home, cycle or walk for short trips, plant and protect native trees, and report environmental violations to municipal authorities.
