Global warming is the rise in average global temperatures since the late 19th century caused by increased greenhouse gas emissions. Temperatures have increased by about 0.8°C overall and two-thirds of the increase has occurred since 1980. Global warming causes problems like loss of polar bear habitat, rising sea levels, and more frequent extreme heat waves. The greenhouse effect traps heat in the lower atmosphere through absorption and emission of infrared radiation by greenhouse gases like water vapor and carbon dioxide. While some solar energy is reflected by the Earth, most is absorbed and keeps the Earth warm through essential physical and chemical processes.

Global Warming
Global warming is caused by increased levels of greenhouse gases from human activities like burning fossil fuels. The greenhouse effect occurs naturally and makes Earth habitable, but human activities have enhanced the effect. Burning fossil fuels and other activities have increased carbon dioxide and methane levels, trapping more heat in the lower atmosphere and leading to warming temperatures worldwide. This global warming will cause significant climate change impacts like sea level rise and more extreme weather unless reduced. The Philippines is especially vulnerable to these impacts due to its geography and development.
Global warming zagidullina_veselova
Global warming refers to the rise in average temperatures around the world due to higher concentrations of greenhouse gases trapping more heat in the lower atmosphere. Key effects include melting glaciers and sea level rise, more extreme weather, and threats to ecosystems. While some warming is natural, human activities like burning fossil fuels are amplifying the greenhouse effect and driving unprecedented changes. Various natural and human factors influence climate both directly and through complex feedback loops.
Global climate change presentation
This document discusses greenhouse gases and global climate change. It defines greenhouse gases as gases that cause the greenhouse effect and trap heat in the lower atmosphere. It then defines global climate change as identifiable changes in Earth's climate that last for decades or longer, and are usually caused by either natural processes or human activities that release greenhouse gases. The document goes on to explain that current climate changes are happening due to both natural causes like volcanoes and plate tectonic movement, as well as human activities that release greenhouse gases. It notes that the effects of human-caused greenhouse gases have been detected throughout the climate system and are extremely likely the dominant cause of observed warming since the mid-20th century.
Greenhouse effect
The greenhouse effect occurs naturally and helps regulate the Earth's temperature. Certain gases in the atmosphere, such as carbon dioxide, methane, and water vapor, trap heat from the sun similarly to how greenhouse gases keep heat inside a greenhouse. However, increased levels of greenhouse gases from human activity are amplifying this effect and causing the planet to warm through global warming, raising sea levels and intensifying weather events like droughts and floods.

Global warming
The document discusses the mechanisms and effects of global warming. It explains that greenhouse gases in the atmosphere reflect heat from the sun back towards the Earth's surface, causing temperatures to rise. Some of the effects mentioned include rising sea levels, melting glaciers, more extreme weather events like floods and droughts, as well as impacts on plants, animals and human communities. The document also provides current examples, noting that between 1900-2000 sea levels rose 10-20cm, glaciers are retreating in mountain ranges, and severe forest fires occurred in 2003 in Russia, America and Portugal due to heat and drought. Plans to address global warming focus on developing renewable energy, promoting energy efficiency, and increasing carbon absorption through activities like tree planting.
Global Warming
Global warming occurs when greenhouse gases like carbon dioxide trap heat from the sun in the lower atmosphere. Normally, the sun's heat would be reflected back into space, but greenhouse gases reflect it back to Earth, causing temperatures to rise. The effects of global warming include climate change, rising sea levels from melting glaciers, more extreme weather like floods and droughts, and threats to plants and animals. Current impacts include rising sea levels threatening islands, glacial retreat of 10-15cm per year in the Himalayas, and record forest fires in 2003 in Russia, America, and Portugal due to heat and drought. Solutions proposed include transitioning to renewable energy, promoting energy efficiency, and increasing carbon absorption through afforestation.

Global warming is an increase in the average temperature of the Earth's atmosphere and oceans. Most of the observed temperature rise since the 1950s has been caused by increasing greenhouse gas emissions. If global warming increases temperatures by over 2 degrees Celsius, the United Nations report predicts water shortages will start, sea levels will rise, and food stocks around the world may run out, leading to migration issues. Solutions proposed to address global warming include using energy-efficient light bulbs, reducing car usage, contributing to recycling programs, using less hot water, planting trees, and preventing burning in forests.

In what manner does burning of fossil fuel
In this presentation the potential causes and effects of global warming and discussed with respect to burning of fossil fuel.
Presentation
The greenhouse effect occurs when gases like carbon dioxide and methane trap heat in the atmosphere, warming the planet. According to scientific consensus, human economic activity is enhancing the greenhouse effect and causing climate change by emitting more of these gases. The impacts of climate change include higher average global temperatures, more extreme weather like droughts and hurricanes, rising sea levels from melting ice caps, and disruptions to ecosystems.
Causes Of Climate Change
The document discusses several potential causes of climate change, including both natural and human factors that can lead to cooling or warming. It describes how the Milankovitch cycles have coincided with ice ages in the past. El Nino and La Nina events involve changes in ocean circulation patterns in the Pacific that impact global weather. The albedo effect describes how ice and snow reflect solar radiation and cool the climate. Deforestation reduces carbon absorption and lowers albedo, while fossil fuel burning increases the greenhouse effect. Volcanic eruptions can cool the climate temporarily by reflecting sunlight.

Global warming is caused by increasing concentrations of greenhouse gases from human activities like burning fossil fuels. This traps heat in the atmosphere and has increased Earth's average surface temperature by 0.74°C over the past century. Some effects of global warming include more extreme heat waves and storms. Reducing pollution from vehicles, factories, and deforestation can help limit further global warming. Greenhouse gases reflect heat radiation back to Earth that would otherwise escape to space, warming the atmosphere in a process called the greenhouse effect.
Lesson1 climate and change GCSE Edexcel B Geography
The document discusses several natural causes of past climate change:
1) Solar activity, with periods of lower sunspot activity corresponding to "Little Ice Ages" and higher activity to warm periods like the Medieval Warm Period. However, solar activity does not correlate with warming since 1975.
2) Orbital cycles known as Milankovitch cycles, which cause ice ages and warm interglacial periods over 100,000 year cycles.
3) Large volcanic eruptions, which eject aerosols that reflect sunlight and cause short-term global cooling lasting several years.
4) Ocean circulation patterns, with changes potentially causing Europe to be 6-8°C cooler during glacial periods due to reductions in the
Global Warming
Global warming is caused by greenhouse gases that trap heat in the atmosphere and raise temperatures. A report from 2500 scientists concluded that humans have caused current planetary warming through activities that release greenhouse gases. Effects of global warming include melting Arctic ice, threatened species, and more extreme weather events like hurricanes. Leaders like Prince Charles, Al Gore, and Barack Obama have expressed concern about global warming and the need for urgent action to address it.
The impacts of global warming
The document discusses the uncertainty in predictions of future global warming. The Intergovernmental Panel on Climate Change (IPCC) projects temperature increases between 1.5-6°C by 2100, but there is uncertainty regarding population growth, economic growth, energy use, and the climate system's response. Sea level rise is projected to be 0.2-0.8 meters by 2090s. There are also concerns about potential tipping points where small changes could trigger larger impacts, such as forest dieback increasing carbon emissions or melting Arctic sea ice reducing albedo. The Arctic is already experiencing impacts like sea ice and tundra retreat threatening ecosystems and indigenous peoples. Africa is also highly vulnerable to climate change impacts due to poverty

Climate change causes
This document discusses climate change across different timescales and possible causes. It notes that climate has varied over geological eras, with ice ages occurring in cycles of around 100,000 years. Historical records show temperature fluctuations, with a cold period from 1400-1850 AD and a warm period from 800-1400 AD. Recent climate data from 1850-2008 shows global temperatures increased by around 0.5°C since the late 1970s, corresponding to an era of global warming. The enhanced greenhouse effect, caused by gases released from burning fossil fuels, has likely contributed to increased warming by trapping more solar radiation. Transportation, industry, electricity, and heating account for over half of all greenhouse gas emissions, with carbon dioxide being the most
Climate change (1)
Climate change refers to significant and long-lasting changes in weather patterns due to both natural causes and human activities. Natural causes include variations in solar energy and volcanic eruptions, while human activities like burning fossil fuels and deforestation emit greenhouse gases that trap heat and cause global warming. As the planet warms, consequences like rising sea levels and changes to agriculture threaten coastal cities and international food systems. Collective action is needed to address climate change and protect the planet.

Climate change is causing major changes in temperature, precipitation patterns, and wind patterns according to the document. Temperature increases are already melting glaciers and sea ice as well as causing more frequent and intense heat waves. Precipitation patterns are also shifting, with wet areas expected to get wetter and dry areas drier. Wind speeds have also been found to slow across parts of the Northern Hemisphere when other regions experience higher temperatures. These changes are negatively impacting society through more extreme weather, declining air quality, and stresses on water supply and quality. Technology has also contributed to increased energy use and fossil fuel burning, exacerbating the climate crisis.
Is climate change natural or man made?
This document discusses whether climate change is natural or man-made. It first defines climate change as a change directly or indirectly caused by human activity that alters the atmosphere's composition beyond natural variability. It then outlines opinions on the issue and parameters to measure climate change such as temperature, precipitation, sea level, solar activity, volcanic activity, and chemical composition. While some argue multiple factors can cause climate change, data on temperature, precipitation, sea level, and chemical composition suggest human activity is the dominant cause of current climate change. The document concludes natural cycles only have a small effect and recommendations are provided for mitigating climate change.
Climate Notes PowerPoint
Climate is defined as the pattern of weather in an area over many years. It is determined by factors like latitude, proximity to large bodies of water, ocean currents, mountains, and urbanization. Climate types are classified using Koppen's system which examines temperature, precipitation, and vegetation. Organisms adapt both structurally and behaviorally to survive in different climates. Climate can change over both short and long periods due to seasonal changes, phenomena like El Niño, variations in atmospheric composition, solar radiation levels, and shifts in Earth's orbit and axis. Current climate change is attributed to increased greenhouse gases from human activities like burning fossil fuels and deforestation.
Global Warm
Global warming is caused by increasing concentrations of greenhouse gases like carbon dioxide and methane from human activities such as burning fossil fuels. The average global temperature has increased by 0.74°C over the 20th century according to the IPCC. While global dimming from aerosols has partially offset warming, aerosol effects are temporary whereas carbon dioxide has effects that last over a century. There is scientific consensus that greenhouse gas emissions are causing climate change, but some debate remains over impacts and responses.

MINDFUL INVESTING
Income is money received for work or through investments over a period of time. It can come from wages, profits, rents, interest or other earnings. Most individuals earn income through work or investments. In most countries, the government taxes income before individuals receive it. Savings is income not spent on consumption. It involves putting money aside in accounts or reducing expenses. Investment is the use of savings to purchase assets with the goal of earning returns such as capital appreciation, dividends or interest. The main differences between savings and investment are their purposes (preserving wealth vs. growing wealth) and risk-reward profiles (low risk-low reward for savings vs. higher risk-higher potential reward for investments). Proper financial planning involves creating budgets

Ocular immunology
The ocular immune response involves local, regional, and systemic components. Locally, the conjunctiva, cornea, anterior chamber, and retina are involved. Regionally, the lacrimal gland and lymph nodes participate. Systemically, the spleen, thymus, and mucosal tissues are engaged. The tear film and its components, such as lysozyme, lactoferrin, and secretory IgA, play an important role in the ocular immune response by protecting the eye from pathogens. Specialized immune structures like the conjunctiva-associated lymphoid tissue (CALT) help regulate immunity in the eye. Dysregulation of the ocular immune system can lead to inflammatory conditions
Minimally invasive glaucoma surgery
MIGS procedures are newer glaucoma surgeries that offer more modest intraocular pressure (IOP) lowering than traditional surgeries, but with a safer risk profile. They are targeted at patients with mild to moderate glaucoma and involve minimally traumatic, ab-interno approaches that preserve the conjunctiva. Common MIGS procedures include implants that bypass the trabecular meshwork (iStent, Hydrus), drain into the suprachoroidal space (CyPass), or excise the trabecular meshwork (Trabectome). Studies show that MIGS procedures lower IOP by 15-20% on average when combined with cataract surgery. Complications are generally mild and
Surgery in open angle glaucoma
Surgeries for open angle glaucoma were discussed, including trabeculectomy.

Global warming
Global warming is the rise in average temperatures due to greenhouse gases like carbon dioxide and methane trapping heat in the atmosphere. The Earth's average surface temperature has increased by 0.8°C since the late 19th century, with two-thirds of that increase occurring since 1980. Effects of global warming include rising sea levels that threaten coastal areas, more severe weather events like hurricanes and fires, and melting of the polar ice caps. To reduce global warming, individuals can drive less, recycle, avoid over-packaged products, plant trees, and spread awareness about reducing greenhouse gas emissions.
Global Warming: Causes, Effects and Solutions
Many researchers, engineers and environmentalists are expressing deep concerns about changes in the overall climate of the planet. Fossil fuels are being continuously used to produce electricity. The burning of these fuels produces gases like carbon dioxide, methane and nitrous oxides which lead to global warming. Deforestation is also leading to warmer temperatures. The hazard of global warming is continuously causing major damage to the Earth's environment. Most people are still unaware of global warming and do not consider it to be a big problem in years to come. What most people do not understand is that global warming is currently happening, and we are already experiencing some of its withering effects. It is and will severely affect ecosystems and disturb ecological balance. Because of the treacherous effects of global warming, some solutions must be devised. The paper introduces global warming, elaborates its causes and hazards and presents some solutions to solve this hot issue. Above all, alternative energy sources (solar, wind, hydro, geothermal, bio mass) need to be seriously pursued. Finding and using renewable sources of energy is one of the methods to combat the ever increasing global warming effectively.
Global Warming.pptx
This presentation discusses global warming, including its causes and effects. It begins by defining global warming as the increase of average world temperatures due to the greenhouse effect, where gases like carbon dioxide trap heat in the atmosphere. It then discusses the greenhouse effect in more detail and lists both human causes like fossil fuel burning and natural causes like volcanoes. The presentation notes several effects of global warming such as rising temperatures, climate change, and threats to ecosystems. It provides statistics on recent temperature increases and ends by suggesting ways to stop global warming and quotes on the topic from leaders.
Causes Of Global Warmingupload
The global warming is caused by increasing concentrations of greenhouse gases like carbon dioxide and methane from the burning of fossil fuels and deforestation. This increases the Earth's average temperature between 0.4 to 0.8 degrees Celsius and especially impacts the poles, melting ice and raising sea levels in a way that alters the global climate and threatens polar animal habitats. The greenhouse effect occurs when gases in the atmosphere, like carbon dioxide and ozone, trap heat from the sun that would otherwise escape Earth.
Global warming
Global warming is the rise in average global temperatures since the late 19th century caused by increased greenhouse gases trapping heat near the Earth's surface. This is due to pollution increasing greenhouse gases in the atmosphere. The consequences of global warming include increased global temperatures, more extreme weather like droughts and hurricanes, and rising sea levels from melting ice caps. To prevent further climate change, we must reduce greenhouse gas emissions by using less fossil fuels and protecting forests.
Climate change itppt(hp2)ariel herrera1
The document discusses global warming and its causes. It states that global warming is an increase in the average temperature of the Earth's atmosphere and oceans, with surface temperatures rising 0.74°C over the past century. The primary cause of global warming is carbon dioxide emissions from the burning of fossil fuels. Increased greenhouse gases like CO2 trap more heat in the atmosphere, enhancing the natural greenhouse effect and amplifying global warming. Effects of global warming include rising sea levels and temperatures, melting ice caps, and more extreme weather events. Solutions proposed are reducing CO2 emissions through energy efficiency and renewable energy.

Global warming refers to the long-term rise in Earth's average temperature due to human activities like burning fossil fuels. Since pre-industrial times, human activities have increased Earth's average temperature by about 1 degree Celsius. It is unequivocal that human influence has warmed the atmosphere, ocean and land. The greenhouse effect occurs naturally and makes Earth habitable, but human emissions of greenhouse gases like carbon dioxide are enhancing the effect and causing global warming. Continued emissions will lead to more extreme weather, higher sea levels, and other damaging impacts. Addressing global warming will require international cooperation on clean energy and adaptation efforts.

Evs project report on effect of global warming
Global warming refers to the long-term rise in the average temperature of the Earth's climate system, primarily due to human activities such as burning fossil fuels and deforestation that increase greenhouse gas emissions. The key causes of global warming outlined in the document are increased greenhouse gases trapping heat in the atmosphere. Some of the major effects of global warming discussed are rising sea levels, more frequent extreme weather events like droughts and heat waves, melting glaciers and ice sheets, and impacts on biodiversity. The document recommends methods to control global warming such as using renewable energy, public transport, and reducing electricity usage to help limit temperature increases and mitigate future risks from climate change.
Global Warming
1. Higher temperatures from global warming threaten dangerous consequences like drought, disease, floods, and lost ecosystems.
2. The accumulation of greenhouse gases like CO2 in the atmosphere from human activities like burning fossil fuels is causing global warming by enhancing the greenhouse effect.
3. The greenhouse effect is the rise in temperature that occurs because greenhouse gases in the atmosphere trap heat from the sun, creating a warmer climate than if the Earth's atmosphere was absent.
Newsletter about global warming - The greenhouse effect from Greece
The greenhouse effect was first established in 1822 by Joseph Fourier, who noted the atmosphere traps heat like a greenhouse. The greenhouse effect occurs when gases like carbon dioxide and water vapor in the atmosphere absorb infrared radiation emitted from the Earth's surface and radiate it back in all directions, warming the Earth's surface. However, increased emissions of greenhouse gases from human activities like burning fossil fuels are enhancing the greenhouse effect and increasing global temperatures, with many scientists predicting a 5 degree Celsius rise by 2040. This will have consequences like sea level rise from melting ice caps and reductions in drinking water and arable land.
The greenhouse effect
Greenhouse gases like carbon dioxide and methane naturally regulate Earth's climate by trapping heat in the atmosphere. However, since the industrial revolution, human activities have increased greenhouse gas emissions through fossil fuel combustion and deforestation. This has led to atmospheric carbon dioxide levels that are now the highest in human history and are predicted to further rise significantly by 2100 without action. The increased greenhouse gases are causing average global temperatures to rise by around 1 degree Celsius already and will likely increase temperatures by several more degrees, with detrimental effects on ecosystems and human societies.
Neutral 10 augmentals
The document discusses the impacts of climate change and global warming. It notes that deforestation accounts for 20% of carbon emissions, equivalent to the US or China. Extremely hot days have increased 150 times in the last 30 years. The Earth's average temperature has risen 1.5°F in the past century, with the climate warming about 10 times faster than previous periods. Major contributors to greenhouse gas emissions are carbon dioxide, accounting for 82% of US emissions. Global sea levels have increased by 8 inches since 1870.
Presentation1
Global warming refers to the recent increase in average surface temperatures worldwide since the late 19th century. This increase in temperature is attributed primarily to human-induced emissions of greenhouse gases like carbon dioxide from the burning of fossil fuels. The main effects of continued global warming are projected to be a rise in average surface temperatures of 3-5°C by 2100 along with a sea level rise of at least 25 meters due to melting ice sheets and thermal expansion of oceans.

Climate Change
Global warming is an increase in the Earth's average surface temperature due to rising levels of greenhouse gases. The presentation discusses the causes of global warming as increased greenhouse gases like carbon dioxide that trap heat in the atmosphere. This amplified greenhouse effect has led to increased global temperatures and threatens sea level rise, more extreme weather, and mass extinctions. Solutions proposed include use of energy efficient appliances, insulating homes, and choosing renewable energy over fossil fuels.
Global warming
This presentation in detail discusses about the Global Warming and its effects. Also the reasons of Global warming.
Climate presentation
The document discusses several key pieces of evidence that show the climate is changing due to human activity:
1) Satellite data shows that while the sun's energy output has remained stable, the Earth has been warming since 1979.
2) Greenhouse gas levels, especially carbon dioxide, are higher now than at any other time in the last 800,000 years due to human fossil fuel use.
3) Computer models used to study past and present climates indicate that the observed warming is only explained when human greenhouse gas emissions are included.

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.

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.

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.

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.

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.
