Solutions proposed to improve the dispute process include treating water as a national resource, limiting actors, and establishing time frames and enforcement bodies.
The document discusses India's need to share river water resources through cooperation between states. It outlines reasons for river water disputes such as uneven water distribution and increasing population. River water disputes can arise from actions that affect upstream or downstream states. Disputes are typically resolved through negotiation facilitated by the central government or tribunals. Important inter-state river water sharing disputes and treaties are mentioned. The document advocates for better water sharing to control droughts and floods, utilize water for agriculture, and promote economic prosperity.
The document discusses how the third world war may be fought over water. As global warming accelerates glacier melting and pollution reduces usable surface water, while population growth increases water consumption sevenfold, water is becoming an increasingly scarce resource. Some areas are facing water stress as resources deplete. Unless habits and policies around water usage change, such as through conservation efforts and cooperative management of transboundary water sources, conflicts over dwindling freshwater supplies could escalate into open warfare between the "water haves and have nots," shaping global geopolitics in the 21st century as oil conflicts defined the 20th. The author calls for action now through water-saving practices to prevent an impending "water war."
Rivers: lifelines of human civilizationnisargsmart
Rivers are natural watercourses that flow towards oceans, lakes or seas. They carry water and dissolved minerals and deposits. River mouths where freshwater meets saltwater oceanic water are highly biologically productive areas. Rivers are important sources of water for households, industry and agriculture, providing food, energy, transportation and irrigation. Dams are structures that hold back water for generating hydroelectricity, irrigation, and flood control, but building dams can submerge fertile plains, displace people, and lose forests and farmland. Dams must also be extremely expensive and built to a very high standard.
The document discusses water management and issues related to water resources in India. It notes that water is a critical natural resource, but that India is facing increasing water stress and scarcity. The document outlines that water is essential for agriculture, industry and households. However, with population growth, increasing demand for water is outpacing available supply. The document summarizes challenges India faces in water management including river pollution, inadequate storage, and conflicts over water access between states and countries. Improved water conservation efforts like rainwater harvesting and integrated management are needed to ensure sufficient water resources for the future.
Water dispute between India and Pakistanbabak danyal
The document discusses the longstanding water dispute between India and Pakistan over the Indus River system. It summarizes that India controls the headwaters of the rivers and Pakistan depends on them for agriculture. In 1960, the Indus Waters Treaty was brokered to allocate water rights between the countries, giving India control of three eastern rivers and Pakistan control of three western rivers. However, recent Indian dam construction projects on the western rivers have exacerbated water shortages in Pakistan and tensions over the treaty remain high.

With this we should be able to end all the water related problems permanently and thus bring peace, prosperity, wealth, health, happiness to the mankind.
Water is essential for all life on Earth. The human body is made up of 45-60% water and water is needed for critical functions like regulating body temperature and transporting nutrients. While the oceans hold the vast majority of Earth's water, less than 1% of water is available as freshwater in rivers, lakes, and groundwater. Given water's unique properties as a solvent and its role in biological and industrial processes, access to clean water is necessary for drinking, sanitation, agriculture, and electricity generation.

It concludes by discussing the quality of groundwater sources in different provinces.
The document discusses the need for a National Water Grid and Peninsular Water Grid in India to address water scarcity issues. It proposes interlinking rivers across the country to optimize water usage and irrigation potential. Some key points discussed include:
- Developing a network of rivers to transfer water from water surplus to deficit areas for irrigation and drinking water needs.
- Potential benefits include 11 million additional hectares under irrigation, 2754 MW of hydroelectric power, and drought mitigation.
- Desalination of sea water using nuclear power could provide drinking water for coastal cities.
- People's participation is needed in watershed management and conservation efforts.
Water covers most of the Earth's surface and is essential for life. The main sources of water for irrigation are surface water from rivers, reservoirs and lakes, and groundwater. Surface water quantity depends on factors like storage capacity, permeability, runoff, precipitation and evaporation which can be impacted by human activities. Groundwater availability varies by location and depth. Water is tapped from these sources through various methods like gravity flow, pumping from wells or rivers. Dams and reservoirs help regulate water supply for irrigation in Pakistan.
The document discusses the unique characteristics of rivers in Kerala, India that originate from the Western Ghats mountain range. It notes that the rivers have short lengths but support a high population density and biodiversity. Six major threats to the rivers are identified: catchment deforestation, dams and diversions, sand mining, incorrect land use, pollution, and encroachments. Three rivers are highlighted as either on the brink of dying (Chalakudy River) or already dying/dead (Periyar and Bharathapuzha Rivers) due to these threats and flow modifications from dams. The document calls for plans to restore rivers to more "living" states through ecological restoration, improved dam management, and strengthened

Recycling and Disposal on SWM Raymond Einyu pptxRayLetai1
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity
Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

This presentation is for us to know that how our Environment need Attention for protection of our natural resources which are depleted day by day that's why we need to take time and shift our attention to renewable energy sources instead of non-renewable sources which are better and Eco-friendly for our environment. these renewable energy sources are so helpful for our planet and for every living organism which depends on environment.
Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.
Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

6. THE MAIN WATER RESOURCE FOR
CHENNAI !
❖ CHENNAI RECEIVES MOST OF THE WATER FROM THE POONDI
LAKE(3231 Mcft), SHOLAVANAM LAKE (881 Mcft), REDHILLS
LAKE (3300 Mcft) and CHEMBARAMBAKKAM LAKE (3645
Mcft)
❖ THE VEERANAM WATER SUPPLY PROJECT ADDED AN
ADDITIONAL OF WATER SOURCE FOR CHENNAI CITY
7. THE VEERANAM WATER SUPPLY
PROJECT
❖ The VEERANAM lake project is to su[pply water to
chennai. Was conceived in 1967 by then Chief Minister of
Tamil Nadu C.N.ANNADURAI, and was been executed
under his successor M.KARUNANIDHI. The project was
been completed in 2004. It was impossible to use any
water from the lake since it had run dry and face-saving
proposal was been adopted by the authorities was to dig
45 deep borewells around the area and the pump
resulting water 235 km(146 miles) to chennai via pipeline.
The length takes around 14 km and this is the largest lake
in the tamil nadu. The credit goes to the ancient people
who has done a wonderful job for us.
9. SHORT SUMMARY ABOUT VEERANAM
LAKE
❖ Veeranam lake( veeranarayanapuram lake) is
located 14 km (8.7 miles) SSW in Cuddalore district,
Tamil Nadu in South India. It is located 1 km(0.62
miles) from lalpet and
235 km (146 miles) from Chennai. It is one of the
water reservoirs from water is supplied to Chennai
City. the lake has a capacity to store 1465 Mcft of
water. Though the level of veeranam lake as dipped
to 323 million cubic feet (Mcft). The same of 180 mld
(million litres a day) was being drawn for city supply.
10. THE LIFE OF AQUATIC CREATURE IN
CHENNAI
❖ The selective fishing using kaccha valai (a special net used to catch
minute sea creatures) is on the rise in the stretch between palaverkadu to
alampara fort near Chennai since the annual seasonal movement of rare
sea species close to shore last month. At least 25 boats venture into sea
every day from various villages to catch rare sea snails, shells and
crustaceans, and each returns at 50 kgs of sea species. The catch
overloaded into private vans immediately and transported to nearby
processing units and they sell it illegally and get money for that after a
week.
❖ The fishes which are been sold illegally will be exported immediately to
the countries like China, Singapore, Malaysia.
❖ This leads to the extinction of the particular species and demand in the
natives
❖ There is no proper pisciculture to maintain the species for long time and
increase it in numbers
