Dr. KulkarniName of the Speaker: Dr Anil Kulkarni

Title of the Seminar: Recent Advances in Himalayan Glaciology [Gallery]

Date and Time: 21st February 2020 (Friday), 4:00 PM

Venue: Lecture Hall, ICWaR


About the speaker: Dr Kulkarni is currently working as a Distinguished Scientist at Divecha Centre for Climate Change, Indian Institute of Science, Bangalore. He is instrumental in developing numerous remote sensing-based methods and models to understand Himalayan Cryosphere. These are widely used to map seasonal snow cover, glacier cover and moraine-dammed lakes. Further, these also are used to estimate glacier mass balance, stream runoff and to understand the influence of climate change on the Himalayan cryosphere. During his initial investigations, Dr. Kulkarni developed a methodology to map Himalayan glaciers using remote sensing data. This methodology was used to prepare glacier inventory of Indian Himalaya, providing information about the distribution of Himalayan glaciers, not available previously to the scientific community.  Dr Kulkarni and his team have recently developed a model based on velocity, slope and flow law to estimate the distribution of ice-thickness. This is being used to estimate glacier stored water and mass loss for Himalayan glaciers.  In addition, he is working on modelling Glacier Lake Outburst Floods in Himalaya. He also organises two weeks of training programs on Glaciology. Due to his significant contribution in the field of glaciology, he received numerous awards such as National Geosciences award, Polar science and cryosphere and team leader award from ISRO.

Abstract: Himalayan mountain range is one of the major Water Tower of Asia and stores a large concentration of snow and glaciers.  Water Towers generate more runoff due to high orographic precipitation and delay release due to storage as snow and Ice. Therefore, water is supplied during the hot and dry season, making many rivers like Indus, Ganga and Brahmaputra perennial.  Indus River considered more vulnerable under future climate change scenarios due to large contribution from snow/glacier melt, large population, high water stress and geopolitical conditions.  In addition, the livelihood of large Himalayan mountain communities also depends on the availability of water from snow and glacier melt. Therefore, periodic assessment of the state of the Himalayan cryosphere is important. In this lecture, I will give a current understanding of Himalayan cryosphere and future challenges. Recently numerous new techniques and models have been developed to estimate glacier volume, mass loss, potential glacier lake sites, assessment of flash flood from Glacier Lake Outburst Flood and effect of climate change of glacier distribution. I will discuss the significance of these contributions and its impact of water security and livelihood on mountain communities.

imageName of the Speaker: Dr. Laurent Ruiz

Title of the Seminar: Critical Zone Science for Water Resource Management in Agricultural Landscapes [Gallery]

Date and Time: 28th January 2020 (Tuesday), 4:00 PM

Venue: Lecture Hall, ICWaR


About the speaker: Laurent Ruiz research interest is to understand and model the interactions between climate, anthropogenic forcings, especially agriculture, and water resources at the landscape scale. He explores how pluridisciplinary approaches, spanning Hydrology, Agronomy, Geochemistry and Social Sciences can help conceiving better management of water and nutrient cycles in agro-ecosystems. His work relies primarily on long term observations carried out within Critical Zone Observatories in France (AgrHys https://www6.inrae.fr/ore_agrhys) and in India (BVET https://mtropics.obs-mip.fr/). He holds his PhD from Montpellier University (France) and is a researcher at INRA and IRD. He has been associated with the Indo-French Cell for Water Sciences at IISc Bangalore since 2002. He is the PI of the ATCHA project (http://www6.inrae.fr/atcha/) focused on the adaptation of Indian agriculture to climate change.

Abstract: In the time of Anthropocene, global changes are questioning the capacity of the planet Earth to sustain the development of human societies in the long term. In the past two decades, this concern has fostered world wise efforts to develop integrated studies of the “Critical Zone” (CZ), the thin layer of the Earth surface, from the top of the canopy to the bottom of the aquifer, hosting the continental biosphere and providing basic human needs such as water, food, energy and ecosystem services. Critical Zone Observatories (CZO) have been set up in various climatic, geologic and human contexts with a wide range of variables being monitored on the long term. Their main challenge is to ensure the actual integration of the multiple scientific disciplines at stake, from geosciences and biological sciences to social sciences, working within a wide range of spatial and temporal scales. Using experiences from France and India, this seminar will illustrate how such integration can produce the knowledge required for effectively addressing environmental issues in agricultural landscapes.

Title of the Seminar: The tyranny of small decisions- living with sub-optimality in the water and waster water sector: experience from the field [Gallery]

Date and Time: 20th December 2019 (Friday), 4:00 PM

Venue: Lecture Hall, ICWaR

About the speaker: S Vishwanath is a Civil Engineer and an Urban Planner. He has 33 years of experience in the water, waste-water and sanitation sector helping design rainwater harvesting, aquifer recharge, wastewater recycling and ecosan systems. He is an Adjunct Professor and teaches a course on the theme – Water at the Azim Premji University, Bengaluru, India (http://azimpremjiuniversity.edu.in/SitePages/vishwanath-s.aspx). He is a Trustee with the Biome Environmental Trust (www.biometrust.org). One of the current projects is to help the traditional well-digging community build a million recharge wells for Bengaluru. He used to write a weekly column called Waterwise for the last 12 years for  The Hindu (http://www.thehindu.com/profile/author/s.-vishwanath/). He has been part of the expert committee which helped formulate the Rainwater harvesting policy and law for Bengaluru, the Waste-water policy for Karnataka and the Water Policy for Karnataka being drafted by the Karnataka Knowledge Commission.

Abstract: The management of water and wastewater is often seen as an institutional issue. Yet in the case of India there are many stakeholders at play apart from institutions and in fact, may crucially be using and in control of more waters and wastewaters than the government. In the quest for sustainable management of resources, optimality is put forward as a goal, whereas a series of sub optimality’s, often in conflict with the optimal, is likely the way forward. How is rainwater harvesting to work in non-optimal worlds? How is groundwater to be used and recharged? What happens to faecal sludge from pit toilets and septic tanks and wastewater in a city ecosystem? Can livelihoods also be included as part of the management of water as a resource? Do policies and standards need a fresh look in this context? Why are we subject to the tyranny of small decisions ?

Some examples and experiences from Bengaluru were discussed in the talk.

Title of the Seminar: Mega-trends in the Growth of Hydrologic Understanding: From Newton to Darwin to Wegener  [Gallery]

Date and Time: 18th November 2019 (Monday), 4:00 PM

Venue: Lecture Hall, ICWaR

About the speaker: Murugesu Sivapalan holds a B.Sc Civil Engineering (University of Ceylon), M.Eng in Water Resources Engineering (AIT, Thailand), and obtained his 1986 Ph.D from Princeton University. He was Professor of Environmental Engineering at the University of Western Australia for 17 years, before joining University of Illinois in 2005. Siva has published on a wide range of topics, including effects of heterogeneity and scale, flood frequency, eco-hydrology and water balance and water quality modeling. He was Executive Editor of the Hydrology and Earth System Sciences journal, and was founding chair of the International Association of Hydrological Sciences’ Decade on Predictions in Ungauged Basins initiative. He is also co-founder of the new subfield of socio-hydrology. Sivapalan has received several awards for his research contributions, including the John Dalton and Alfred Wegener Medals of the European Geosciences Union, the Robert Horton Medal of the American Geophysical Union and the International Hydrology Prize of the International Association of Hydrological Sciences. Sivapalan was awarded the Prince Sultan Bin Abdulaziz International Prize for Water (Creativity Prize) in recognition of his role in developing and leading the new field of socio-hydrology. He is a Fellow of the Australian Academy of Technology and Engineering and recipient of the Centenary Medal of the Australian Government for service to hydrology and Environmental Engineering. He is currently visiting ICWaR as Satish Dhawan Visiting Chair Professor.

Abstract: Hydrologic science has undergone transformative changes over the past 100 years, from early empirical approaches to rigorous approaches based on the fluid mechanics of water movement on and below the land surface. Challenged by limitations of traditional Newtonian approaches, and embracing a Darwinian, co-evolutionary Earth system science perspective, the pursuit of hydrologic science is now guided by altogether new questions and methodologies, with a particular focus on interactions and feedbacks between parts of the Earth system that co-evolve, giving rise to the adoption of comparative hydrology. In the emergent Anthropocene, this co-evolutionary view has expanded to involve feedbacks with human-social processes as well. Hydrologic science is now entering a globalization era with a focus on new phenomena that emerge from regional and global teleconnections of the expansion of the human footprint, calling for the adoption of novel Wegenerian approaches to understand the Earth system and the role of water in it. In this lecture, I will present key milestones in the transformation of hydrologic science from Engineering Hydrology to Earth System Science.

AK  Name of the Speaker: Dr. Axel Kleidon

Title of the Seminar:  Understanding hydrologic cycling from a thermodynamic Earth system perspective   [Gallery]

Date and Time: 16th October, 2019 (Monday), 4:00 PM

Venue: Lecture Hall, ICWaR

About the speaker: Axel Kleidon studied physics and meteorology at the University of Hamburg, Germany and Purdue University, Indiana, USA. He received his Ph.D. in 1998 in meteorology from the University of Hamburg. After his PostDoc at Stanford University he joined the faculty of the University of Maryland in 2001. Since 2006, he leads an independent research group at the Max-Planck-Institute for Biogeochemistry in Jena, Germany.  He regularly teaches courses on renewable energy and thermodynamics of the Earth system.His research interests fall into the highly interdisciplinary field of Earth system science and include topics such as the thermodynamics of Earth system processes, land-atmosphere interactions, the influence of vegetation, climate change, the Gaia hypothesis, and natural limits of renewable energies. He is the author of more than 100 scientific papers, co-founder and co-chief editor of the interdisciplinary science journal Earth System Dynamics of the European Geoscience Union (EGU), and has co-edited several books. He is the author of “Thermodynamic Foundations of the Earth System”, published by Cambridge University Press, and is currently completing a book project “Energy – A Very Short Introduction”, which will be published by Oxford University Press within the next year.

Abstract: The hydrologic cycle is an integral part of the whole Earth system, converting substantial amounts of energy. These conversions follow the laws of thermodynamics, which set the directions and impose fundamental limits, yet these also result in interactions and feedbacks that emphasise the need for an Earth system perspective.  In this talk, I provide the background for this thermodynamic description of the hydrologic cycle and use examples to show how thermodynamic limits in combination with a formulation of the dominant interactions can be used to describe the emergent behaviour.  I show how this approach can be used to provide simple, yet physically-based estimates of evaporation and how hydrologic cycling responds to global climate change.  I close with an outlook on potential future applications, highlighting the generality of the approach as energy, its conversions into other forms, and interactions are  at the very core of literally every Earth system process

Abstract: Groundwater is the lifeline of drinking, irrigation and industrial water supply in India. With an extraction of ~ 250 km3 annually, India are the largest user of Groundwater in the world. Though a plethora of government documents and policy papers highlighting planned and coordinated extraction management of groundwater resources is available, in practice, it has been hardly followed. So is the case of artificial recharge, often referred as medicine of all groundwater woos but mostly being executed in a segmented and unplanned manner often divested with scientific understanding of the area. Groundwater extraction has never been planned in conjunction with its annual recharge. The reason is the lack of structured approach by the Government. We use more than 85% of our extracted groundwater for irrigation through ~ 22 million wells owned by farmers. In absence of any regulatory mechanism, coupled with sops offered by the State Govts, mainly in the form of energy subsidy, has initiated a reckless extraction, creating havoc. The latest estimates reveal that about 20% of the assessment units are either overexploited or are alarmingly close to it. Artificial recharge and rain water harvesting is considered as a panacea for groundwater depletion. The Centre and State Government Departments spend huge public money mainly through various schemes like MNGREGS. The recharge structures are hardly dovetailed with local aquifer understanding, thus lacking in two basic arenas, location and design, and resulting in sub-optimal benefits. The other important issue is the lack of source water, which is primarily monsoon runoff in India. In arid and semi-arid areas, dearth of source water is a major challenge. Inter-basin water transfer should also considered for recharging the depleted aquifer. Moreover, because of climate change, the monsoon pattern is changing. The traditional understanding of types of structures and their designs needs to be revisited to accommodate and withstand high intensity rainfall.There are areas where acute groundwater mining has rendered such a condition that even if all possible recharge measures are successfully implemented and working, the resource would continue to deplete. Such a situation warrants strict direct or indirect regulation of extraction. The NAQUIM outputs are enhancing our knowledge and understanding of the prolific as well as depleted aquifer systems. The time has come to think of mega recharge schemes in hydrogeologically suitable areas.

Title of the Seminar: Frontiers of Hydrology Research – Role of Isotope Tracer Applications [Gallery]

Date and Time: 16th July, 2019 (Tuesday), 4:00 PM

Venue: Lecture Hall, ICWaR

About the speaker: Dr. R D Deshpande is currently the Chairman of Geosciences Division of Physical Research Laboratory (PRL), Ahmedabad, which is a unit of Department of Space Govt. of India. He has a Ph.D. from the M.S. University of Baroda, Vadodara, based on his isotope hydrology research at PRL. Dr. Deshpande’s research is focused on understanding the complex hydro-geological and hydro-meteorological processes using stable and radioactive isotopes as a tracer tool. His research in the field of Isotope Hydrology is well-known in India and abroad. He carried out a Regional Aquifer System analyses in the North Gujarat Cambay region to explain the temperature and helium anomalies in the groundwater vis-à-vis tectonic frame work of the region. He has explained the origin and distribution of high levels of fluoride in ground waters of North Gujarat and suggested remedial measures against the endemic fluorosis. He has assigned radio-carbon and Helium accumulation ages to ground waters of Gujarat and shown that groundwater being exploited today in the water stressed areas was recharged several tens of thousands of years old. This highlighted the need for artificial recharge and rain water harvesting. He observed for the first time the kinetic isotope fractionation during liquid condensation under supersaturated condition. He has identified the zones of groundwater helium anomalies along the Narmada lineament as a signature of active hydrothermal circulation. Dr. Deshpande is the Principal Coordinator of the National Programme on Isotope Fingerprinting of Waters of India (IWIN) which is a multi-institutional collaborative research programme, aimed at isotopically characterizing various hydrological cycle components (sea surface water, atmospheric water vapor, rain water, groundwater and river water) to understand subtle aspects of interaction and exchange between them. Dr. Deshpande set up a state-of-the-art Isotope Ratio Mass Spectrometer (IRMS) laboratory under the IWIN programme, dedicated for oxygen and hydrogen isotopic analyses of water and vapor samples. His research is based on numerous wide-spread and exhaustive field sampling across the country for collection of samples and their isotopic analyses. He has published more than 40 peer reviewed research papers based on this fieldwork. Dr. Deshpande is nominated as a Mission Expert in Isotope Hydrology by International Atomic Energy Agency (IAEA), Vienna. He has served as a member of the several Expert and Advisory committees of MOWR, MOES and the DST. He is an expert member in the Board of Studies in Geology at M.S. University of Baroda and Research Development Committee of the M.G. Science Institute, Ahmedabad and Kachchh University, Bhuj. He is a Fellow of the Geological Society of India and the Gujarat Science Academy.

Abstract: The contemporary hydrology is faced with great challenges of known problems and the greater of unknowns. Problems of water scarcity, anthropogenic pollution, geogenic contamination, dwindling surface flows, inequitable distribution and salinity ingression have turned cliché in hydrology community. The scientific processes underlying these hydrological problems are quite well understood and can be mitigated by appropriate field measures, treatment technologies, improved water use efficiency and policy interventions enforced with strong political will. While we grapple with these known water resource problems, there lies beyond a mind-boggling ignorance about certain aspects of functioning of hydrological systems, their natural course and response to perturbing stimuli. This ignorance about certain hydrological processes does not hinder the ongoing efforts of mitigating existing problems; therefore, it is presently on the back-burner. However, for a fundamental hydrology researcher, this ignorance defines the frontier of research. Filling these hydrological knowledge gaps will become essential in the coming decades to face the imminent scenario. This knowledge gap may seem only academic in nature at present but is bound to have societal implications. Some of the important questions in the above backdrop are: (1) What is the relative contribution of Western Disturbances and Indian Summer Monsoon in Himalayan precipitation, rivers and cryosphere? (2)  How are wetlands in Northeast India participating in monsoon rainfall? (3) How to identify signatures of static groundwater being circulated into the surface and atmospheric components of hydrology? (4) How much of submarine groundwater discharge can be tapped without damaging marine ecology? (5) Are there deep sources of self-recharging and self-replenishing groundwater (seawater distillate or otherwise) other than static water? (6) What is the contribution of recycled moisture in Indian precipitation? (7) How to perceive the effect of varying Himalayan riverine influx in the Bay of Bengal? (8) Can the Bay of Bengal surface water cool below threshold temperature for feeding moisture? These and many more questions define the frontier of basic research in hydrology which can be defined only by multitude of tools and expertise in conjunction with each other. Isotope application is one such tool which can play an important role in this basic research pursuit. Progress hitherto and the possibilities will be discussed in the seminar.

Abstract: India is one of the most water-stressed countries in the world. However, despite an appreciable increase in funding for water research, high-quality science, that is usable by stakeholders remains elusive.There is an urgent need for “use-inspired” research on questions that actually matter to stakeholders, trans-disciplinary research, and empirical primary data on fundamental science questions. But what does such research entail? What do we understand, what questions still remain to be answered? Finally, how does science actually translate into policy and practice? What are the policy levers or game changers and how do we ensure that scientific research actually informs efforts to adopt them.

Name ofpurnima jalihal the Speaker: Dr.Purnima Jalihal

Title of the Seminar: Desalination – Technical challenges and Road Ahead

Date and Time: 29th May, 2019 (Thursday), 4:00 PM

Venue: Lecture Hall, ICWaR

About the speaker: Dr. Purnima Jalihal is a senior scientist who heads the Energy and Fresh Water group in the National Institute of Ocean Technology, India.  She has coordinated many first – ever projects in ocean energy and desalination.  She has jointly coordinated the world’s first  ever ocean thermal gradient based desalination plant at Kavaratti island in the Lakshadweep group  in the Arabian Sea which has helped transform the lives of the small island community which had a serious lack of drinking water.  For this work she was awarded the Vishwakarma Medal in 2006 by the Indian National Science Academy.   This success led to more plants in islands and a demonstration plant offshore. Dr. Purnima is now attempting to scale up the technology and power such plants using ocean renewable energies.  She has several firsts in the area of ocean energy as well, including a wave powered desalination system at  Kerala, a wave powered navigational buoy and a hydrokinetic turbine. Her areas of specialization include offshore structures, floating and structural dynamics, renewable ocean energies and desalination.She has MS and  PhD degrees in Civil Engineering from Duke University , USA.   She is currently working on a large scale desalination project at Tuticorin thermal power station using the condenser reject heat and a self powered thermal desalination at Lakshadweep   using the power generated from the temperature gradient. Additionally, she played a pivotal role is getting Cabinet’s approval for India to become Member Country of the International Energy Agency’s Ocean Energy Systems (IEA-OES) Technology Collaboration Program (TCP) with the NIOT as the participating agency in 2016 and held the first Ex Co meeting in India in November 2017.

Abstract: The current scenario where water stress dominates most of the regions in India warrants new technological solutions for fresh water generation.  Desalination has been on the horizon for some decades now due to large plants in the Gulf.  There are several types of desalination methods predominantly thermal and membrane based.  The technical challenges include proper methods for intake and discharge of seawater, optimization of thermodynamic parameters for thermal systems, chemicals and bye products for membrane methods and energy requirement optimization. The location, water quality and environmental impact and other parameters like availability of steam all need to be considered for appropriate selection of the desalination method.  Desalination of brackish water as well as seawater promises to be a good solution to the water crisis.  Desalination methods are energy intensive and towards lower carbon footprint, use of renewable energy forms need further exploration and development.  Cost and energy reduction for thermal technologies and safe disposal of by products for membrane methods is the need of the hour.

Abstract: Karnataka state is highly vulnerable to drought. In the last 13 out of 16 years (2002-2018), most parts of Karnataka has been subjected to severe drought. The successive drought condition has resulted in shortage of water for drinking, irrigation, etc. Also, groundwater levels are depleting and quality of water is getting deteriorated.
Most important component in management of drought is related to weather system – its monitoring, forecasting and adopting. Karnataka State Natural Disaster Monitoring Centre (KSNDMC) has taken proactive measures and has built a robust mechanism with a multi-disciplinary approach to provide Science and Technology based solution to tackle drought in Karnataka. The state-of-the-art ICT tools are being used extensively at the level of data collection, converting data into information, identifying and mapping vulnerable areas, forecast-alert-advisory dissemination to the end-user.
KSNDMC has designed and installed a dense network of Solar Powered & GPRS enabled Telemetric Rain Gauge (TRG) stations covering all the 6425 Grampanchayaths (~25 sq km each) and Telemetric Weather Station (TWS) at all the 747 Hoblis (~250 sq km each) and 173 micro-watersheds to collect data and information on factors triggering drought or flood. . The weather data thus collected at every 15 minutes through these weather monitoring stations, analyzed at near-real time, maps and reports are being generated and disseminated to the customized users through auto-mode. The necessary web-applications has been developed in-house.
The customized alerts/early warnings, weather information, forecast and advisories are being disseminated through email, SMS, dynamic web-portal, social media, electronic and print media. The weather related information, forecast and advisories are disseminated directly to the farmers, through interactive help-desk “VARUNA MITRA” on 24 x 7 basis. It is helping the farmers to plan their agricultural activities, minimize the crop loss due to any weather aberration. The initiatives taken up by KSNDMC have been helping the stakeholders for planning and executing drought mitigation measures at micro-level, to adopt resilient agriculture practice and efficient water management techniques.

Venue: Lecture Hall, ICWaR

About the speaker: Dr. Bharadwaj Amrutur is a Professor in ECE Department and Chairs the Robert Bosch Centre for Cyber Physical Systems, IISc Bangalore. After completing his B.Tech in Computer Science and Engineering in 1990 from Indian Institute of Technology, Bombay, he did his M.S. in Electrical Engineering in 1994 from Stanford University, USA. Thereafter, he pursued his Ph.D. in Electrical Engineering in 1999 from Stanford University, Stanford, CA, USA.

Abstract: Cities and Utilities have started deploying connected sensors as part of their smart cities effort. Examples include pollution sensors in Pune, water sensors by BWSSB, smart electricity meters, smart water meters etc. However there is still a large gap in terms of general understanding of how to do this deployment in the most cost effective manner, while extracting the maximum value out of the data. He discussed some of the technical gaps in sensor fabrication, sensor calibration, deployment optimization, data access and multi-sensor analytics and talked on some of his team’s ongoing work in the context of air quality sensors and pilot activities in Pune and Electronics City.

Dr. Sharad Lele1Name of the Speaker: Dr. Sharachchandra (Sharad) Lele

Title of the Seminar: Reforming Water Governance: Philosophy, Hydrology and Institutional Analysis

Date and Time: 20th February, 2019 (Wednesday), 4:00PM

Venue: Lecture Hall, ICWaR


About the speaker: Sharachchandra (Sharad) Lele got a B.Tech. in Electrical Engineering in IIT Bombay (1984) but then decided that environmental studies were more exciting and socially relevant. So, he did an M.S. on the environmental impacts of large dams at the Indian Institute of Science, Bangalore (1987) and then a Ph.D. in Energy and Resources from the University of California, Berkeley (1993), focusing on forest use in the Western Ghats.

Abstract: Karnataka, like most of the peninsular states in India, is facing a serious water crisis. Basins have closed, groundwater is depleting, baseflows have dried up, and existing water is being inequitably distributed. Conventional responses tend to be supply side, lacking an integrated hydrological understanding, and top-down. A paradigm shift is required in multiple dimensions: the normative goals, the world view, the hydrological underpinnings and the institutional arrangements. He discussed the rationale and key elements of such a paradigm shift and make a case for using an interdisciplinary value-based framework for all efforts in reforming water governance.

Abstract: Urban development consists of a collection of processes that have variable effects on water budgets, groundwater recharge, and stream flow flow.  Some of the processes that were focused on in this seminar are infiltration of storm water, changes to evapotranspiration, lawn irrigation, water supply pipe leakage, impervious surface cover, and infiltration of groundwater into wastewater pipes.  The methods used to investigate these drivers of urban base flow have been data analysis, field data collection, and mathematical modeling. Watershed-scale storm water infiltration was implemented as part of low impact development in a watershed that was converted to suburban development in Clarksburg, Maryland, USA.  Stream base and total flow both were found to increase during development, relative to flow in reference urban and forested watersheds.  The driving processes are suggested to be a reduction in vegetative cover and evapotranspiration, and an increase in focused groundwater recharge with watershed-scale storm water infiltration.  In Baltimore, Maryland, USA, water supply pipe leakage and impervious surface cover were found to be less important drivers of subsurface storage compared to infiltration of groundwater into wastewater pipes. Current work on drivers of urban base flow focusing on semi-arid areas were discussed.
