Land, water and local people – A case study of the Bangalore Mysore Infrastructure Corridor

This study traces the impact of the Bangalore–Mysore Infrastructure Corridor (BMIC) project on the lakes in the villages around the project area

Lake

This thesis/report presents the findings of a study that was conducted for the fulfillment of the Masters degree at the School of Habitat Studies, Tata Institute of Social Sciences. The study traces the impact of the current mega infrastructure project, the Bangalore–Mysore Infrastructure Corridor (BMIC) project,  undertaken between the two cities of Bangalore and Mysore on the lakes in the villages around the project area by describing the case of the state of lakes from three villages.

The BMIC project envisions redirecting development away from Bangalore in order to ease urban density in the heart of the city by including five new townships and 193 village clusters. The total area it covers is and comprises of expressway, peripheral road, link road, five townships and village clusters. The project’s advertised primary goals are to cut the driving time between the two cities of Bangalore & Mysore from three and a half hours to 90 minutes, thereby bringing in greater mobility.

The study aimed at:

  • Understanding the evolution of BMIC project
  • Exploring the lake management practices in the three village before and after project implementation
  • Exploring the differential impact on the village communities and the linkages between land rights and water rights

The study found that the project led to land use change from agricultural rural areas in the periphery to urban land use. In the process, the landscape surrounding the lake and the village was transformed from a wetland-lake ecosystem, which acted as a village commons to a private property owned by a private entity or a fenced system disconnected from the ecosystem. This led to a negative impact on lakes with the lakes being inadequately maintained, polluted with sewage and solid waste and with depleting water quality and quantity as many of them were leased out to private entities. Lakes increasingly began to be looked upon as land property for profit-making leading to a shift in the view of lakes from ‘common property’ to ‘private property’.

There were several strong protests and agitations from a variety of civil society groups and several PILs were filed in the High Court. However, it was found that the local community had been left behind in the planning process and the interests of the most vulnerable and disadvantaged were taken over by the private interest groups for making profits. The traditional users who maintained the lakes were also gradually sidelined in this process. Thus, lack of consideration and value given to water resources such as lakes in the planning of the project led to gradual destruction of the ecosystems, biodiversity of the area along with depletion in quality and quantity of the lakes, poor access of the marginalised to this valuable water resource.

The study argues that lakes provide numerous essential ecosystem services and thus maintain the substantial biodiversity of the region. Therefore, every time when there is a need to develop new residential layouts or industries or infrastructure projects or expand existing ones, concern should be to preserve the eco-system of the lakes. It is thus necessary that the the government agencies involved co-ordinate and integrate themselves in a better manner to identify features of the lake such as to demarcate the lake areas and the Raja Kaluves and make plans to protect them. Government agencies must also involve traditional community-based users such as fodder collectors and fishermen etc, in the planning process itself.

The study ends by making the following recommendations:

  • Protect lake systems while developing new layouts, industries and infrastructure projects
  • Local rights to be recognised for better use of lakes
  • Participation of women, young people in lake management
  • Moving away from civil engineer’s model for lake restoration, islands should be made away from human activity and must be positioned at adequate distance from the mainbund and water-edge
  • Live fencing of lakes instead of stone wall or mesh fencing
  • New process of sewage treatment in a decentralised manner

Chapter 34 Meteorological Science

1 . Weather forecasting is not an exact science. It’s primarily based on observation. But attempts are being made to make  it as scientific as possible. Comment 50 words  page 482
It is prediction of weather through application of the principles of Physics and gathering of meteorological statistical data. It is difficult to gather this data and this data keeps changing with changes in atmospheric conditions. The best of predictions may be vaid for two or three days after which predictions have to be revalidated.

2. What is synoptic meteorology? 483
It characterises the weather over a large region at exactly the same time in order to organise information about prevailing conditions. Synchronised observations for a specific time are plotted on a map for a broad area from which a general view of the weather in that region is gained.

3 . Describe the techniques adopted to gather meteorological data 100 words 484
Technological advance since the 1960s have led to a growing reliance on remote sensing, particularly the gathering of data with specially instrumented weather satellites as well as observations from ships, aircrafts, radiosondes and Doppler radar. This information is sent to meteorological centres where the data are collected, analysed and made into a variety of maps and charts.

To predict the weather by numerical means, atmospheric models have been developed by using mathematical equations to describe how atmospheric pressure, temperature and moisture will change over time. The equations are programmed into a computer which determines how different variables will change with time.

4. What is the window of meteorological deduction? 484
Weather forecasts made for 12 and 24 hours are typically quite accurate. Forecasts made for two to three days are good. Beyond about 5 days, the forecast accuracy falls off sharply.

5 . Describe the practical applications of weather forecasting. 100 words 484
Agriculture is a major area for use of weather forecasting. Planting and harvesting can be planned better if weather patterns are estimated. It is important in India due to the dependence of the agricultural sector on the monsoon. It has also become important for aviation and sea transport.

Many ocean going vessels as well as military ships use optimum ship routing forecasts to plan their routes in order to minimise lost time, potential damage and fuel consumption in heavy seas. Airlines carefully consider atmospheric conditions when planning long flights so as to avoid the strongest head winds and ride with the strongest tail winds.

Marketing stores require weather forecasts to help with the timing of sales and products ranging from snow tyres to summer clothes. International trading of foodstuffs such as sugar, wheat, corn and coffee can also be severely affected.

6 . How many regional centers  of Meteorological observation are there 485
There are 6 at New Delhi, Mumbai, Kolkata, Chennai, Nagpur and Guwahati.

7 . What s the significance of INSAT? 485

India was the first developing country in the world to have its own geo-stationary satellite, INSAT, for continuous weather monitoring of this part of the globe and particularly for cyclone warning.

8 . Describe the major achievements  of  the (IMD) Indian Meterological Department. 100 words. /486
It has Doppler weather radars installed for more accurate weather forecasting; installation of 100 Digital Cyclone Warning Dissemination systems along the Andhra coast; a Mountain Meteorology Centre was established at Delhi for prediction of avalanches, flash floods and landslides; a new long range prediction model that gives July rainfall for helping Kharif crop sowing; lowering of detection and response times by upgrading the seismic monitoring system.

An Earthquake Risk Evaluation Centre was established at Delhi for seismic micronization. There are also customised forecasts for various other important applications like power distribution, water resources, defence, emergency response and adventure sports.

9 . What are the Agro Advisory services rendered by the IMD 486
It has developed a new long range prediction model that gives more lead time as well as July rainfall as an additional forecast for helping Kharif crop sowing.

10 . What s NCMRWF? Describe it’s vision 50 words 486
The NCMRWF (National Centre for Medium Range Weather Forecasting) was established as the premier institution in India to provide medium range weather forecasts and to render agro advisory services to farmers.

its vision is to become the preferred choice for NWP (Numerical Weather Prediction) guidance over the Indian monsoon region , to develop an earth weather modelling and assimilation system, especially for the monsoon system, to develop newer applications and reach out to society at large, and constantly striving to improve accuracy and consistency.

11 . What is global modeling? 487
NCMRWF runs 2 global spectral models (T-80, T-170) which produce daily global forecasts. The horizontal resolution of these models are 150km and 75km respectively. The atmospheric system they attempt to predict is chaotic. An ensemble prediction system, which involves generation of multiple forecasts as a function of the uncertainty has been developed.

12 . What is Mesoscale modelling? 487
They are essential for accurate prediction of high impact weather such as severe thunder storms, mountain weather forecasts, cloudbursts and cyclones. The mesoscale models (MM5 & ETA) are run up to 72 hours on real-time for high impact weather prediction using initial and boundary conditions from the global forecast model.

13 . What are extended range forecasts? 50 words 488

Currently, the dynamic approach is used for extended range (monthly) prediction based on simulations from the global atmospheric model. Probability of occurrence of excess, normal or deficient rainfall for 6 homogenous regions of the country is calculated.

A more accurate couples system is being developed to understand and predict the monsoon environment a season in advance. Experiments are being conducted to reduce model systematic errors and uncertainties.

14 . What  are Ocean State forecasts? 488
They are in great demand for ship routing, fisheries, tourism, oil exploration and port and naval operations. Ocean surface parameters form global and mesoscale models derive most of the ocean and wave models in the country in both real time and research mode. NCMRWF runs a daily global ocean wave model to predict significant wave heights, peak wave direction and wave period.

15 . What are the goals of NCMRW?

It hopes to develop crop model based application tools for agro-advisories, use of remote sensing products to address variability within the agro-climatic zones, and precision farming using GIS.

16 . What s cloud seeding?

It involves seeding clouds with tiny particles to bring more precipitation from them. There two ways to seed clouds. The first uses the coalescence process of rain formation. Small water drops are injected into the base of a cloud, which grow in size by collision with other particles until they are heavy enough to fall down.

The second method employs the ice crystal process of rain formation where small particle of silver iodide are injected into a cloud. These particles act as ice crystals. Water vapour from the surrounding liquid droplets evaporates and freezes onto the iodide particles, which grow larger. The growing crystals eventually become heavy enough to fall as precipitation.

Chapter 33. Earth Sciences in India

1. Describe India’s coast line, economic zone and continental shelf.  How far does the maritime belt , economic, belt and Fisheries belt extend.   Page (470, and 480)

India’s coastline sprawls over a distance more than 7500 km long, and its territory includes 1256 islands. Its exclusive economic zone covers about an area of 20 lakh sq.km and the continental shelf stretches up to 350 nautical miles from the coast.

The continental shelf comprises of the sea bed and sub-soil of the submarine areas that extend beyond its territorial sea throughout the natural prolongation of its land territory to the outer edge of the continental margin, or to a distance of 200M from the baselines from which the breadth of the territorial sea is measured, where the outer edge of the continental margin does not extend up to that distance.

Territorial waters, or a territorial sea, as defined by the 1982 United Nations Convention on the Law of the Sea ]is a belt of coastal waters extending at most 12 nautical miles (22 km; 14 mi) from the baseline (usually the mean low-water mark) of a coastal state. The territorial sea is regarded as the sovereign territory of the state, although foreign ships (both military and civilian) are allowed innocent passage through it; this sovereignty also extends to the airspace over and seabed below.

If the distance between two States is less than 24 miles, a line drawn midway is the Fisheries belt. Within this restricted territorial belt, the littoral state (adjacent state) has exclusive rights to fish)

An exclusive economic zone extends from the outer limit of the territorial sea to a maximum of 200 nautical miles (370.4 km) from the territorial sea baseline, thus it includes the contiguous zone. A coastal nation has control of all economic resources within its exclusive economic zone, including fishing, mining, oil exploration, and any pollution of those resources. However, it cannot prohibit passage or loitering above, on, or under the surface of the sea that is in compliance with the laws and regulations adopted by the coastal State in accordance with the provisions of the UN Convention, within that portion of its exclusive economic zone beyond its territorial sea. Before 1982, coastal nations arbitrarily extended their territorial waters in an effort to control activities which are now regulated by the exclusive economic zone, such as offshore oil exploration or fishing rights .Indeed, the exclusive economic zone is still popularly, though erroneously, called a coastal nation’s territorial waters.

Contiguous zone

The contiguous zone is a band of water extending from the outer edge of the territorial sea to up to 24 nautical miles (44 km; 28 mi) from the baseline, within which a state can exert limited control for the purpose of preventing or punishing “infringement of its customs, fiscal, immigration or sanitary laws and regulations within its territory or territorial sea”.

2. Describe the organization of Ministry of Earth Sciences. What areas are covered by it? 470/ 100 words
it was created in 2006 after merger of India Meteorological Department (IMD), National Centre for Medium Range Weather Forecasting (NCMRWF), Indian Institute of Tropical Meteorology (IITM), and Earth Risk Evaluation Centre (EREC) with the then ministry of Ocean Development.

The ministry’s mandate is to look after atmospheric sciences, ocean science and technology and seismology in an integrated manner. It has to formulate and implement programmes relating to long term economic and technological development. It seeks to create a framework for understanding the complex interactions among key elements of the earth system.

3. What services does the Ministry of Earth Sciences provide? 471

4. Write a note in hundred words on the Antarctica Treaty
It came into force in 1961 after ratification by 12 countries then active in Antarctic science. The treaty covers the area south of 60 degree south latitude. Its objectives are to demilitarise Antarctica, to establish it as a zone free of nuclear tests and disposal of radioactive materials, and to ensure that it is used for peaceful purposes only; to promote international scientific cooperation in Antarctica; and to set aside disputes regarding territorial sovereignty.

The treaty remains in force indefinitely. 44 countries have acceded to it. 27 nations, including India have consultative status. They have adopted over 200 recommendations and negotiated 5 separate international agreements, collectively, these are known as the Antarctic Treaty System (ATS).

5 . What is the significance of Antarctic Research? 100 words 471-472
Antarctica provides great scope for the conduct of scientific research for the benefit of mankind. It is an impressive, pristine laboratory which has enabled scientists and researchers to detect and monitor global environment phenomena such as depletion of the ozone layer, global warming, and sea level changes. It has supplied data crucial to weather forecasting in the southern hemisphere.

Glaciological research provides important data about the heat exchange budget. The earth’s geomagnetic field renders Antarctica especially suitable to the study of polar terrestrial interactions and cosmic rays that travel from outer space.

The continent’s environment provides unique opportunities to study the specialised adaptations of organisms. Human biology and medicine provides information on the physiological adaptation of man to extreme climates and isolation.

6 . Describe in hundred words the Indian Antarctic Research Programme.
It began in 1981, when the first Indian expedition was flagged off from Goa. Subsequently, 25 expeditions have been undertaken, including one to the
Wedell sea and another one to the Southern Ocean for krill ( a kind of fish) exploration.

MAITRI, the Indian station is situated in the Schirmacher Oasis. It has all modern facilities to carry out research in various disciplines such as biology, earth sciences, glaciology, atmospheric sciences, meteorology, cold region engineering, communication, human physiology and medicine. It has a capacity to accommodate 25 people in the winter.

India was admitted to the Antarctic treaty in 1983. It was admitted as a member of the Scientific Committee in Antarctic Research (SCAR) in 1984. India became a member of the Convention on the Conservation of Antarctic Marine Living Resources (CCAMLR) in 1986 and built its second permanent station ‘Maitri’ in 1988-89.

7 . Describe the activities of the National Centre for Antarctic and Ocean Research (NCAOR)  473

10 . Describe India ‘s Ocean Research. 100 words 476

It is being focussed on multi-disciplinary research on the physical, chemical, geological and biological aspects of the Indian Ocean. Ocean vessels can also be used for campaigns in validating satellite oceanographic data, assessment of marine resources and for various technology demonstration activities.

Dedicated cruises were also undertaken for summer monsoon and winter monsoon coverage of the Bay of Bengal as well as the Andaman sea. A centralised FORV (Fisheries Oceanographic Research Vessel) Data and Referral center has been set up at Kochi. Survey and exploration of poly-metallic nodules is also being carried out in about 100 blocks to refine resource estimation further and to identify first generation mine sites.

With a view to protecting and preserving the marine environment, the quality of coastal waters is being continuously assessed at many locations along the coast. The two indigenously built coastal vessels- Sagar Purvi and Sagar Paschimi are being utilised for continuous monitoring of pollution levels in the coastal areas.

Sagar Kanya and Sagar sampada have been carrying in surveys for discocering economic resources of India’s exclusive economic zone.

11 . What is the National Data Buoy Programme? 100 words  476
Collection of time series observations of oceanographic and surface meteorological parameters over Indian seas are necessary to improve oceanographic services and predictive capability of short-term and long-term weather/climatic changes. The National Data Buoy Programme was started in 1997 for such observations.

These data buoys carry sensors to measure wind speed, wind direction, air pressure, air temperature, conductivity, sea surface temperature, current speed, current direction, and wave parameters. The buoys are equipped with global positioning system, beacon lights and satellite transceivers. Some buoys can measure parameters like radioactivity, light attenuation in three wavelengths and dissolved oxygen. Power to the buoys is provided by solar panels and chargeable battery packs.

Applications of this programme include Environmental impact assessment, Meteorology, oceanography, fisheries, validation of satellite data, offshore installations, ports and coastal structures, and shipping.

12. Marine organisms have attracted attention as a potential source for drugs. Explain in 100 words 477
Dozens of promising products, including cancer therapy made from algae and a painkiller taken from snails, are in development at research laboratories. Other products, such as an anti-inflammatory drug extracted from the Caribbean sea whip, and a potential antiosteoporotic drug of hexacoral origin are under review.

Among other areas of research are the discovery, development and production of drugs from marine bacteria, fungi, microalgae, sponges and opisthobranch molluscs.

After successful completion of clinical trial, the systematic collection, extraction and biological evaluation of seaweeds, mangroves, anemones, sponges, starfish, seahorses would be carried out to identify other potential drugs. Product development is on-going in 7 areas- anti-diabetic, anti-hyperlipidaemic, anti-anxiety, anti-hyperglycaemic, anti-bacterial, anti-tumour and larvicidal.

13. What is COMAPS? 478
The Coastal Ocean Monitoring and Prediction System (COMAPS) has been in operation at 82 locations for collection and analysis of 25 parameters relating to physical, chemical and biological characteristics of water and sediments. Based on this data, the areas of concern have been identified and steps are being taken to prevent and control the causes of pollution.

14 . What are submersibles? 478
A submersible is a small vehicle designed to operate underwater. A feasibility study has been carried out regarding the possibility of developing indigenous submersibles capable of operating at a depth of 600m in the first phase and 2500m in the second phase.

15. Describe the integrated coastal and marine area management Programme (ICMAM)? 50 words. 478

16.  What are polymetallic nodules? Describe the activities in this field? 100 words
Polymetallic modules on the ocean floor are considered to be a treasure house of much needed metals. The potato shaped, largely porous modules, are found in abundance carpeting the ocean floor. The nodules are of economic importance because they contain, besides manganese and iron, nickel, cobalt, copper, lead, molybdenum, cadmium, vanadium, titanium, of which cobalt, copper and manganese are considered to be of strategic importance.

In August 1987, India became the first country to be allotted 150,000 sq. km of area in the central Indian ocean for exploration and exploitation of polymetallic nodules under certain obligations and was given the status of a Pioneer Investor. The Department of Ocean Development which has been designated as the nodal agency responsible for implementing the deep seabed mining programme, has drawn up a long term plan to fulfil these obligations.

17 . What are the important types of marine data being studied now? 481
