Drought is defined as an extended period of time with less than normal rainfall resulting in water shortage. It can be caused by improper rainfall distribution over time or space, rather than total amount. Drought is difficult to define due to its slow onset and end. Its effects include damage to agriculture, reduced stream and groundwater levels, and increased migration, child labor, and school dropouts. Students can help address drought by constructing rainwater harvesting systems, promoting watershed management, increasing forest cover through tree planting, and adopting conservation practices while discouraging water waste and pollution.

PPT on drought in india
Drought is an extended period of deficient water supply caused by significantly below average precipitation. It can impact ecosystems, agriculture, and local economies. Some plant species have adaptations like reduced leaves or waxy coatings to tolerate drought. Past droughts in India have led to major famines and tens of millions of deaths in the 18th-20th centuries. Indian agriculture depends heavily on the summer monsoon, and monsoon failures can result in water shortages and below average crop yields in drought-prone regions.

Droughts
Droughts are periods of time when there is a lack of water on land caused by low rainfall from high pressure weather systems. Without sufficient water, plants and crops do not grow properly, animals die, and food shortages for people can occur. Droughts turn land into deserts if they persist for long periods. Australia experiences drought about once every 18 years due to its variable climate and experiences about 3 bad years out of every 10 on average.
6 Introduction To Drought
Drought is defined as a continuous period of dry weather that can vary in length between countries. It can be caused by seasonal changes in weather patterns like the Hadley cell and Inter-Tropical Convergence Zone, leading to wet and dry seasons in some regions. Long term droughts over multiple years can have disastrous consequences, affecting both human and natural systems. The consequences of drought include food shortages and the need for food aid when rains fail. Various groups like nomadic pastoralists have adapted to seasonal droughts, while long term management strategies are needed to address extended drought crises.
Water in the earths processes vocabulary2
The water cycle describes the continuous movement of water on, above, and below the Earth's surface, driven by energy from the sun. Water evaporates from oceans, lakes, and soil into the atmosphere, where it condenses to form clouds and precipitates as rain or snow back to the Earth. Some precipitation is absorbed into the ground to become groundwater, while some runs into streams, rivers, and lakes before eventually returning to the oceans, completing the cycle. The water cycle is crucial for sustaining life on Earth.
Deiva ict
The document provides an introduction to hydrology and the hydrological cycle. It notes that over 97% of the Earth's water is found in oceans, while less than 3% is located on land in glaciers, ice caps, groundwater, rivers, lakes, and atmospheric water vapor. The hydrological cycle describes the continuous movement of water on and below the Earth's surface through processes like evaporation, condensation, precipitation, runoff, and groundwater. Water is constantly changing forms through this cycle, whether rapidly or over millions of years.
The Hydrosphere
The hydrosphere refers to all the water on, above, and below the Earth's surface, including oceans, lakes, rivers, groundwater, and water in the atmosphere. The water cycle transfers water between different states as it circulates around the Earth through processes like evaporation, condensation, precipitation, and collection. Water pollution threatens the hydrosphere when contaminants are introduced into bodies of water.
Drought presentation

Properties of water and its global distribution
The total volume of water on Earth is estimated at 1.386 billion km³ (333 million cubic miles), with 97.5% being salt water and 2.5% being fresh water. Of the fresh water, only 0.3% is in liquid form on the surface. In addition, the lower mantle of inner earth may hold as much as 5 times more water than all surface water combined (all oceans, all lakes, all rivers).
Ubana sarah jane
The document discusses Earth's hydrosphere and water pollution. It defines the hydrosphere as the combined mass of water found on, under, and over the surface of a planet. Insolation provides the energy for evaporation and transpiration from various surfaces. Water vapor is added to the hydrosphere through these processes. The document then discusses water pollution, noting that pollutants are discharged directly or indirectly into water bodies without adequate treatment. Common pollutants include sewage, sludge, garbage and toxic chemicals from industries. About half of all sewage worldwide is dumped untreated into water bodies.
The water cycle
The water cycle describes how water is circulated and recycled around the Earth. Water evaporates from surfaces, transpires from plants, and condenses in the atmosphere to form clouds. Precipitation occurs when clouds become too full, returning the water to Earth's surface where it collects in oceans, lakes, rivers, and groundwater or runs off into these water bodies to restart the cycle.
U09 Hydrosphere

Introducing the Hydrosphere
The Earth is over 70% water, with the hydrosphere consisting of all water on, under, and around the planet. Water exists in all three states of matter, as ice and glaciers, liquid in oceans, seas, lakes and rivers, and as a gas in clouds and water vapor. The majority of Earth's water is contained in its oceans.
Drought
Drought is defined as a prolonged period of abnormally low rainfall that negatively impacts living conditions and agriculture. It is difficult to determine the exact onset and end of a drought. Drought can be caused by improper rainfall distribution over time and space, as well as an imbalance between precipitation and water usage. There are different types of drought including meteorological, hydrological, agricultural, and socio-economic droughts that have increasingly severe impacts on weather, water resources, crop yields, and the economy. While drought is a natural phenomenon, its effects are exacerbated in developing countries by issues like overpopulation, deforestation, and unsustainable water usage.
Hydrosphere and water pollution
The document discusses the hydrosphere, which is composed of all water on or near Earth, including oceans, seas, lakes, rivers, streams, and water vapor in the atmosphere. The oceans are the major element of the hydrosphere and are constantly in motion. All water in its various forms present on Earth constitutes the hydrosphere, with most water present as liquid water on the surface and underground. The hydrosphere covers about 70% of Earth's surface and is home to many plants and animals.

This document proposes a dimensionless approach to analyze the stability behavior of switching converters characterized as nonlinear time-periodic systems. It establishes an equivalent stability theory for such systems based on topological equivalence and investigates stability in terms of homeomorphic systems. The approach introduces a normalized map to formulate parametric relationships and derive stability patterns by calculating approximate solutions using the Galerkin method and eigenvalue analysis. The method is applied in detail to a case study of a Zeta PFC converter to demonstrate how it can reveal parametric relationships and facilitate stable converter design.

Water resources
Only 2.5% of the Earth's water is freshwater, with over two-thirds locked in icecaps and glaciers. Less than 1% of global freshwater is readily accessible for human use. Fresh water supplies are under pressure due to increasing population, consumption, pollution, and climate change effects like more extreme droughts and floods. Many regions and countries will likely experience serious freshwater shortages within 20 years if problems are not addressed. Desalination remains an expensive option restricted to wealthier nations.
Scientific Facts on Water Resources
Water is essential for human survival and well-being and important to many sectors of the economy. However, resources are irregularly distributed in space and time, and they are under pressure due to human activity.
How can water resources be managed sustainably while meeting an ever increasing demand?
Gonzales trajico report (chapter4)
Water is essential for life on Earth and is continuously circulated through various reservoirs in the hydrosphere in a process known as the water cycle. The water cycle involves evaporation of water from oceans, rivers and lakes into vapor which rises into the atmosphere. Water vapor condenses to form clouds and precipitation falls back to the Earth's surface, completing the cycle. Most of Earth's water is saline and located in oceans, while freshwater is found in ice sheets, groundwater, atmosphere and other reservoirs with varying residence times.

Water consumption &purification
- Most of Earth's water is saltwater found in oceans, while only 3% is freshwater. Of this freshwater, over two-thirds is frozen in glaciers and ice sheets.
- Water is continually cycled through the Earth in the hydrological cycle between oceans, atmosphere, and land via evaporation, condensation, precipitation, and infiltration. This cycle provides freshwater for human and ecosystem uses.
- Groundwater makes up about 96% of unfrozen freshwater and provides 25-40% of the world's drinking water by flowing through aquifers. However, groundwater quality can be impacted by natural and human-caused contaminants.
Hydrosphere
The document summarizes key aspects of Earth's hydrosphere and hydrologic cycle. It describes the hydrosphere as including all of Earth's water found in oceans, glaciers, streams, lakes, soil, groundwater, and air. It also notes that Europa and possibly Ganymede and Enceladus may have subsurface oceans. Additionally, it provides details on the distribution and movement of water between the oceans, atmosphere, biosphere, lithosphere, and the water cycle which traces this movement between stores and spheres.
Draught natural disaster
This document discusses drought, including its definition, causes, classification, effects, and government policies to combat it. Drought is defined as an extended period of deficient precipitation that causes water shortage for people and crops. Common causes of drought include low rainfall, high air pressure, lack of monsoon winds, depletion of forests and groundwater, and global warming. Droughts are classified as meteorological, agricultural, or hydrological based on their physical aspects and impacts. Effects of drought include economic losses, food shortages, environmental damage, and social impacts like conflicts and migration. The document provides a case study of the severe 2002 drought in Rajasthan, India and outlines various government programs to address drought like rural employment schemes and waters
Hydrological cycle by Ar. Papon
The document discusses the hydrological cycle, which describes the continuous movement of water on, above and below the surface of the Earth. Water evaporates from oceans, lakes and rivers, rises into the atmosphere, condenses into clouds, and falls back to the Earth's surface as precipitation like rain or snow. It then either runs off into rivers and lakes or seeps back into the ground in a repeating cycle. The hydrological cycle involves the processes of evaporation, condensation, precipitation, runoff, and infiltration as water circulates between the atmosphere, land, and oceans in its three states of solid, liquid, and gas. Understanding this global water cycle is essential for planning sustainable water resources for the future.
Water, Use and Management
The document discusses various topics related to water use and management. It begins by describing the hydrologic cycle and major water compartments. It then discusses current water use, reasons for freshwater shortages, the impacts of dams and diversions, and approaches to water management. The document also explores potential solutions that could be employed if conventional water management strategies prove insufficient, such as cloud seeding, desalination, and increasing water use efficiency.
The World's water -Hydrosphere
Water is the most precious gift of mother nature. Hydrology is the scientific study of the origin, occurrence, properties, distribution, and effects of water on the Earth’s surface, in the soil and in the underlying rocks, and also in the atmosphere. This module explain's the distribution of water in the global hydrosphere.
WATER
it is a description about water.it includes the main uses of water and the natural sources of water.also it tells about water pollution.this presentation tells us that do not waste water because it is more precious.
Water resourse
The document discusses water resources and related topics. It begins by introducing the student project and listing the contents to be covered, which include the hydrosphere, features of water, types of water resources, uses of water, the water cycle, water as a precious resource, freshwater resources, water pollution, water-related diseases, floods, droughts, and dams. It then provides details on these topics, describing things like the water cycle, groundwater resources, surface water resources, uses of water in agriculture, industry, domestic applications, and hydropower generation. It also discusses issues like water pollution, diseases related to water, and environmental problems caused by dams.
Water resources
Water is an essential resource for all life on Earth, yet only a small percentage is available for human use. Most of the Earth's water is salt water located in oceans, while freshwater is found in ice caps, glaciers, groundwater, lakes, and rivers. However, water scarcity is a growing problem as over two billion people lack access to clean drinking water and agriculture, which uses 70% of the world's freshwater, is inefficient. Conservation of our limited freshwater resources is critical to sustain life and protect the environment.
DESERT HYDROLOGY
This document provides an overview of deserts and their characteristics. It defines deserts as areas that receive less than 10-15 inches of precipitation per year. Deserts form due to factors like lack of rainfall, rain shadow effects of mountains, and lack of vegetation. Water is the dominant agent of erosion in deserts, though wind also plays a role. Deserts are characterized by internal drainage basins, ephemeral streams, playa lakes, and groundwater-fed oases. Groundwater recharge in deserts is difficult to quantify due to low amounts and long time lags, but can occur through deep aquifers or during rare heavy rainfall events. Desert groundwater also commonly contains high levels of inorganic elements and contamination.
grade 11 chapter 4 module Earth Science: Water Resources
Water is found in various reservoirs on Earth and is constantly cycling between them through evaporation and precipitation in the water cycle. The largest reservoir is the oceans, which hold about 97.5% of Earth's total water supply. Freshwater makes up only 2.5% and is stored in glaciers, groundwater, lakes, rivers, the atmosphere and soil. The movement and distribution of water between these reservoirs is crucial to sustaining life.
1585913834_UNIT_32.pdf
This document discusses water resources and issues related to their over-exploitation and management. It notes that while water covers 70% of the Earth, only 3% is freshwater and a small fraction of that is available for human use. Nearly 90% of India's water is used for agriculture. The document outlines over-utilization of surface and groundwater resources, which has led to problems like decreasing water tables, land subsidence, saltwater intrusion in coastal areas, and drying of wells. Droughts and floods are also discussed, including their causes and effects on environments, economies, and human and animal populations. Solutions for managing water resources like dams, desalination, and rainwater harvesting are mentioned.
Hydrospheremae 110217043911-phpapp01
The hydrosphere includes all of Earth's water found in oceans, glaciers, streams, lakes, soil, groundwater, and air. It interacts with and influences the other spheres like the lithosphere and biosphere. Water is distributed between these spheres and moves through the hydrologic cycle, being held in oceans, atmosphere, and on land in liquid, solid, and vapor forms. Other celestial bodies like Jupiter's moons Europa and Ganymede may also contain subsurface oceans beneath thick ice shells.
Exogenous disasters drought
Hazards which originate above the surface of the earth (in the atmosphere) are called exogenous hazards.

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.

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.

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.
Recycling and Disposal on SWM Raymond Einyu pptx
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:
• Resource Allocation.

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.

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.

- 3. FEATURES: It is a slow onset disaster and it is difficult to demarcate the time of its onset and end. Any unusual dry period which results in a shortage of useful water. It can occur by improper distribution of rain in time and space and not just by its amount. It is a negative balance between rainfall and water use in geographical region.
- 5. AN EYE OPENER: About 2.7% of total water is available on the earth is fresh water of which 75.2% lies frozen in polar region and another 22.6% is present as ground water. Approximately 80% of earth’s surface is covered with water but 1% of it is fresh water that we can use. The rest is available in lakes, rivers, atmosphere, moisture, soil& vegetation.
