Drought presentation
This presentation discusses the impact of drought on the people of Senegal and Sudan. Drought is a weather-related natural disaster that affects large regions for months or years by reducing food production and water supplies. While drought harms many communities, some individuals can benefit economically, such as sellers who can charge higher prices for scarce goods. The presentation examines the specific challenges faced in Senegal and Sudan, including problems securing clean water, impacts on daily life and food security, and effects on the global economy. Solutions proposed to address drought include building water pipes, planting more trees, and constructing dams to store rainwater.
Derek Arndt - Water Crisis March 11, 2013
This document discusses drought and climate change. It notes that drought is a natural part of the climate in some regions, but that climate change is exacerbating drought conditions. As the global water cycle intensifies with climate change, dry areas are expected to become drier and wet areas wetter. The data and climate models support this trend. The document also explains that drought is defined by insufficient water to meet demands, with both natural and human factors influencing supply and demand. High temperatures from climate change act as an additional stress. The author argues that communities must prepare comprehensive plans to manage drought risks.
(Human impact on the environment)
Climate change is the most important effect of global warming and is causing a host of changes globally. These include species extinction, changes in disease distribution, starvation, poverty, and more frequent extreme weather. South Africa is already experiencing more heat waves and droughts becoming longer, while some areas see more rainfall. We must take actions like afforestation, reducing emissions, and public awareness campaigns to address global warming and the greenhouse effect.
Drought ppt
Drought is caused by a prolonged period of below average precipitation over an extended time, such as a season or more. This results in a shortage of available water that can adversely impact vegetation, animals, and people. Droughts are influenced by factors like increased anticyclones, global warming, overpopulation, overcultivation, and deforestation. Consequences of drought include hunger, thirst, disease, wildfires, and social conflicts that can lead to migration or relocation. Australia experienced years of drought in the early 2000s that resulted in millions of livestock deaths and temporary relocations until floods eventually provided relief.
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.
Academic writing
Global warming is one of the major environmental issues today caused by greenhouse gases from industrialization. It refers to the dramatic rise in average global temperatures, which scientists predict will likely change the climate through altered rainfall patterns and more severe weather like typhoons. Higher temperatures are also expected to cause sea levels to rise and coastal flooding, as well as decrease crop production. This diagram identifies the causes and effects of global warming to help understand academic writing on this topic.
Effects Ofglobal Warming.Ppt2
Global warming is caused by greenhouse gas emissions from burning fossil fuels and transportation, which trap heat in the atmosphere like a blanket. This causes rising global temperatures and climate change. Effects of global warming include more extreme weather like hurricanes and flooding, as well as droughts, wildfires, rising sea levels, and threatened wildlife and ecosystems. Global warming affects everyone on Earth through damage from extreme weather and changes to agriculture and food supplies.
The Correlation Between Climate Change and Natural Disasters
Climate change is exacerbating natural disasters like wildfires, droughts, and hurricanes according to researchers. Wildfire seasons have increased from 5 to 7 months since the 1970s due to higher temperatures and less soil moisture. Droughts are also worse as the atmosphere holds more moisture from warmer temperatures, preventing rain. Hurricanes are expected to become more intense as well, with stronger winds and more rainfall from a warmer ocean and atmosphere. Addressing climate change may help limit damage from these increasingly severe weather events.

- Drought can have varying effects depending on location, from being a slight inconvenience in MEDCs to risking famine and disease in LEDCs. MEDCs may face issues like water restrictions and crop failures, while LEDCs could experience lack of water for crops, animals, and human consumption.
- Students will describe global drought risk areas, particularly in Africa, and research solutions like water storage, projects, and sustainability in both MEDCs and LEDCs.
Climate change
The document discusses climate change and its causes and effects. It notes that climate change is caused both by natural factors like volcanic eruptions but humans are a significant driver through activities like carbon emissions from industry, transportation, and pollution. Some of the impacts of climate change include warmer temperatures, melting glaciers leading to rising sea levels, changes in species ranges, more extreme weather events, coastal flooding, and reduced food production impacting malnutrition. While some countries may see economic benefits from a warmer climate, overall climate change poses serious global risks. Collective action through changes like using public transportation, renewable energy, and diet can help address it.
Keiths drought ppt
Drought is a period of below-average precipitation that results in water shortages. It can last for months or years and significantly impact ecosystems, agriculture, and local economies. Drought is caused by factors like low precipitation, dry seasons, climate change, and human activities like overfarming and deforestation. Some areas that are particularly prone to drought include Ethiopia, Eritrea, and Somalia in the Horn of Africa. Common consequences of drought are reduced crop yields, dust storms, famine, wildlife migration, and conflicts over scarce resources. Drought preparedness plans focus on prediction, monitoring, impact assessment, and response.

Drought management in rangelands
This document discusses types of drought and drought management in rangelands. It describes three types of drought: meteorological, agricultural, and hydrological. Meteorological drought is defined by a lack of precipitation. Agricultural drought impacts soil moisture and crops/animals. Hydrological drought decreases water levels in rivers, lakes, and groundwater. The document outlines causes of drought and its effects on rangelands, including lack of forage/water and increased wildfires. It recommends management strategies like providing supplemental feed, vaccinating animals grazing toxic plants, reducing herd size, and temporarily moving animals to less drought-stricken areas.

Global warming is causing an increase in average global temperatures due to increased greenhouse gas emissions. This is leading to more frequent and intense hurricanes for three key reasons:
1) Warmer ocean temperatures provide more energy to fuel developing hurricanes.
2) Higher temperatures cause increased evaporation and more water vapor in the atmosphere, allowing hurricanes to strengthen more rapidly.
3) Data shows a rise in the number of strong hurricanes (categories 3-5) from the 1850s to present day as global warming has increased.
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.
The global-warming
Global warming and climate change are terms for the observed century-scale rise in the average temperature of the Earth's climate system and its related effects.
Multiple lines of scientific evidence show that the climate system is warming.
Temperature changes vary over the globe. Since 1979, land temperatures have increased about twice as fast as ocean temperatures. Ocean temperatures increase more slowly than land temperatures because of the larger effective heat capacity of the oceans and because the ocean loses more heat by evaporation

Lesson5impacts climate and change Edexcel Geography GCSE B
The document discusses the potential impacts of climate change around the world and in specific regions. Some key impacts that could occur globally include increased risks of food insecurity, water scarcity, and extreme weather events. Developing nations are expected to face greater challenges in adapting to climate change impacts. Specific regions may experience threats such as sea level rise endangering coastal communities, shifts in agricultural production, increased disease prevalence, and disruptions to water supplies from glacier melting. Bangladesh is highlighted as one country particularly vulnerable to climate change due to its low-lying geography and population density.
Global warming by Sumair Iqbal
This document discusses global warming and contains information about its causes and effects as well as several surveys related to views on global warming. It defines global warming as an increase in average surface temperature due to greenhouse gases and lists some long-term effects like rising sea levels and stronger extreme weather events. The document also includes poll results on views of the causes of global warming and priorities for government action, as well as surveys on the helpfulness of seminars and priorities for addressing global warming.
Chapter 30
The document discusses factors that influence Earth's climate and ecosystems. It explains that solar energy drives ocean currents, wind, and the water cycle, which produce different climates around the world. Mountains also impact weather patterns and temperature variation. Life requires nutrients, energy, water, and an appropriate temperature range. The distribution of terrestrial biomes is determined by rainfall and temperature, and some of the major biomes discussed include tropical rainforests, savannas, deserts, chaparral, grasslands, temperate deciduous forests, coniferous forests, and tundra. Each biome has characteristic environmental conditions and plant communities.
Water cycle and weather
The document discusses the water cycle and weather. It explains that the water cycle is driven by solar energy and involves evaporation of water from sources like the ocean into water vapor, transpiration of water vapor from plants, condensation of water vapor into clouds, and precipitation in forms like rain or snow that falls back to water sources below to repeat the cycle. It also discusses different types of weather events like storms that can form from the water cycle and become dangerous, such as hurricanes, tornadoes, floods, or blizzards.
Global Warming
Global warming is caused by greenhouse gases trapping the sun's energy in the atmosphere and causing the Earth's temperature to rise. As the planet continues to warm, sea levels will rise and more extreme weather events like hurricanes will occur due to warmer ocean temperatures. Coastal areas will be flooded and species will die off as ecosystems are disrupted by the changing climate. To mitigate these effects, individuals need to reduce their carbon footprint by using less energy and resources, while governments should implement policies to transition to renewable energy sources and lower emissions.
Climate change
Climate change is defined as the change in average weather conditions, including rising global temperatures caused by increased levels of carbon dioxide and other gases trapping heat in the atmosphere. If left unaddressed, climate change will have widespread effects like rising sea levels, more extreme weather, shifting seasons, and threats to both wildlife and agriculture due to warmer temperatures and ocean acidification. Individual actions like reducing greenhouse gas emissions by walking or biking more, supporting clean energy initiatives, and preventing pollution can help address the climate change problem caused by human activities.
Globa warming by Miłosz Jurek
Global warming is caused by increasing levels of greenhouse gases like carbon dioxide and methane in the atmosphere from human activities such as burning fossil fuels and deforestation. Research shows global temperatures have increased by about 0.5 degrees Celsius over the past 100 years and the rate of increase is accelerating, with the hottest years on record occurring in the past two decades. Potential impacts of further global warming include rising sea levels, more extreme weather events like droughts and hurricanes, species extinction, and spread of diseases. The United States is a large contributor to greenhouse gas emissions despite having only 4% of the world's population.
Global warming By Siddharth Koyal
Global warming is caused by the rise in greenhouse gases like carbon dioxide from human activities like burning fossil fuels. The average temperature of the Earth has increased by 0.8°C since the late 19th century, with two-thirds of the increase occurring since 1980. While natural factors can influence climate, the current warming pattern cannot be explained without including the effect of human-emitted greenhouse gases. If warming continues unchecked, impacts are expected to intensify and include rising sea levels, stronger storms, species disruption, and more floods and droughts. Reducing emissions through actions like clean energy and more efficient use of resources can help mitigate the effects of global warming.
drought indian case studies
Drought occurs when a region receives consistently below average precipitation over an extended period, resulting in water shortages. Drought can have substantial impacts on agriculture and regional economies. In India, drought has historically led to tens of millions of deaths from famines in the 18th-19th centuries. Indian agriculture is heavily dependent on the summer monsoon, and failure of the monsoons can result in below average crop yields, impacting parts of India like Maharashtra, Karnataka, Haryana, Gujarat, and Rajasthan. The document then discusses various physical and climatic factors that can cause drought, as well as human impacts like overuse of water resources and depletion of forests.
Drought management Culture of pakistan By Mr Allah Dad Khan Agriculture Exp...
This document discusses drought management and outlines steps to mitigate drought impacts. It begins by defining drought as a temporary decrease in average water availability. Drought events have increased in severity and frequency, producing socioeconomic and environmental impacts. While drought occurrence cannot be controlled, its impacts can be mitigated through appropriate surveillance and management strategies. The document then discusses various measures for combating desertification and mitigating drought impacts, including water resource management, sustainable agriculture, biodiversity conservation, poverty eradication, and policy planning. It emphasizes the importance of monitoring using satellite data, ground surveillance, and strengthening capacities for implementation of early warning systems and response measures.
drought project
The document presents the development of a decision support system for drought monitoring in Sindh province, Pakistan. It outlines the objectives of identifying drought prone areas using satellite data, developing a methodology to determine drought severity, and relating meteorological and agricultural drought impacts. The methodology uses MODIS NDVI and LST data, as well as NCEP climate data, to calculate the Standardized Precipitation Index (SPI) and Temperature Vegetation Dryness Index (TVDI) for drought monitoring and assessment. Time series graphs of SPI values at the district and provincial level in Sindh are analyzed to understand drought patterns and severity over time.

Droughts can be caused by a lack of rain or snow over a period of time due to changes in wind and pressure patterns. High atmospheric pressure can prevent air from rising and forming rain clouds. A persistent high pressure system in an area can lead to drought by prolonging sunny, dry weather. Droughts also occur when wind currents do not deliver enough water vapor from oceans inland to areas that need it.

The document discusses global warming and its effects. Global warming is caused by greenhouse gases trapping heat in the atmosphere, causing the planet to warm up. This warming is harming many plants and animals by raising sea levels, causing more extreme weather, and making some regions hotter and drier. Extended drought periods can devastate crops and livestock if they do not receive enough rain over a long time. The greenhouse effect is exacerbated by human activities and is a major factor influencing higher temperatures worldwide.
Evs ppt
This document discusses drought, including its definition, types, causes, history in India, and effects. It notes that drought is a condition of acute water scarcity caused by significantly lower than average rainfall over an extended period. There are three main types of drought: meteorological, based on rainfall amounts; hydrological, based on water levels in supplies; and agricultural, referring to insufficient water for crop growth. Key causes discussed include low rainfall, soil erosion, global warming, and deforestation. The document outlines some of the most drought prone areas in India and provides a table showing drought years from 1801-2010.
DROUGHT AND LANDSLIDE
This document discusses drought and was submitted by several students to their professor. It begins by defining drought and then discusses the main causes of drought such as temperature changes, air circulation patterns, soil moisture levels, and the supply and demand of water. It also covers the effects of drought including hunger, disease, wildfires, impacts on wildlife, social conflicts, reduced electricity generation, and migration. Prevention methods involve better water management through interlinking resources, monitoring water levels, changing agricultural practices, and developing water storage. Control measures include prioritizing water use, identifying root zones, irrigation techniques, applying mulch, and checking soil moisture.
Climatic drought
Drought refers to a prolonged period of abnormally low rainfall, leading to a shortage of water. A drought can last for several months or years. Sometimes, droughts are declared for a full district for a few years.
It can have a substantial impact on the ecosystem and agriculture of the affected region and harm to the local life and economy. This module highlights the basics of climatic drought.
Drought and Salinity by sohail
This document discusses drought and salinity. It defines different types of drought including meteorological, agricultural, hydrological, and socioeconomic drought. It also discusses the causes of drought such as lack of rainfall, climate change, human activities, and overexploitation of water resources. The economic, environmental, and social effects of drought are outlined. The document then defines soil salinity and discusses how it can occur naturally or through irrigation. It explains how irrigation can lead to salt accumulation over time and the consequences this has for plant growth, infrastructure, and water quality.
Drought ( Disaster Management)
Drought is a prolonged period of deficient precipitation that causes water shortage, impacting vegetation, animals, and people. There are three main types of drought: hydrological drought refers to deficiencies in surface and subsurface water supplies; meteorological drought involves below average precipitation; and agricultural drought occurs when there is not enough water for crops to grow. Causes of drought include both natural factors like weather patterns and global warming, as well as human factors such as overpopulation, overcultivation, deforestation, and over extraction of water. Effects of drought include hunger, famine, disease, wildfires, and social conflicts. Preventive measures involve practices like growing drought resistant crops, rainwater harvesting, and developing irrigation facilities. The Sa
Impacts of climate change on important fruit crops of Rosaceae family
The document discusses the impacts of climate change on fruit production of the Rosaceae family. It begins with introducing climate change and its causes. It then examines how various climatic factors like temperature, rainfall, humidity, wind and frost affect fruit production. Increased temperatures can inhibit growth and development or promote pest and disease incidence. Insufficient chilling can impact flowering and yield. The document also summarizes some research papers. One paper finds temperature and rainfall trends are negatively impacting apple production and diversity in India. Another analyzes fruit set and yield of apricot cultivars under subtropical conditions in Turkey.
Climate change
The document discusses the impacts of climate change on fruit production of the Rosaceae family. It begins with introducing climate change and its causes. It then examines how various climatic factors like temperature, rainfall, humidity, wind and frost affect fruit production. Increased temperatures can inhibit growth and development or promote pest and disease incidence. Changes in rainfall patterns also impact fruit crops. The document analyzes specific impacts like shifts in suitable cropping areas and changes in apple production and diversity in the Kullu valley of India. It provides evidence that temperature and rainfall trends have negatively impacted apple crops in the region. Finally, it discusses results of a study on fruit set and yield of apricot cultivars in Turkey's changing subtropical climate.
Exogenous disasters drought
Hazards which originate above the surface of the earth (in the atmosphere) are called exogenous hazards.
Life sciences lesson
This document discusses how climate affects biomes. It defines climate and biomes, and explains how temperature, precipitation, and other climate factors help determine the type of biome that exists in a given region. Specific climate conditions, like tropical vs. cold temperatures, and wet vs. dry conditions, influence the plants and other species able to survive in an area. The document then provides examples of different biomes in South Africa and how their climates shape the native vegetation and wildlife. It concludes by explaining how climate influences plant growth, soil quality, biodiversity, and which types of organisms can thrive in different climatic zones.
Disaster Management(Drought)
Drought is caused by drier than normal conditions that can lead to water supply problems. The 2013 drought in Maharashtra, India was one of the worst in 40 years after low rainfall. Drought is caused by factors like high temperatures, low soil moisture, demand exceeding supply, and changes in weather patterns. Effects of drought include hunger, lack of drinking water, disease, impacts on wildlife, migration, social conflicts, and war. Precautions to prevent drought include conserving water usage and collecting excess water.

Soil is important as it provides nutrients for plant growth, acts as a habitat for many organisms, and stores water for plants. Soil quality depends on factors like its nutrient content, texture, and ability to retain water. Threats to soil include erosion from overgrazing, poor farming practices, and damage from human activities, which can lead to soil degradation and loss of fertile land. Conservation methods aim to protect soil quality and prevent erosion, such as contour plowing, terracing, no-till farming, crop rotation, use of windbreaks, and controlling water runoff. The type of soil that forms is influenced by properties of the parent rock material and climatic factors like temperature and precipitation.
Air Fountain, Turning Air into Water!
Atmospheric water generation (AWG) is a process that involves capturing water vapor from the air and condensing it into a liquid form. There are several methods for achieving this, including cooling the air to a temperature at which water vapor condenses and using a desiccant to absorb moisture from the air. AWG has several potential applications, including producing water in areas where it is not possible to access a reliable source of clean water. It is also a sustainable and energy-efficient solution for producing water, as it does not rely on the use of finite resources like groundwater or surface water. However, mainstream methods for finding and storing water, such as accessing traditional sources and using infrastructure to distribute it, are becoming less reliable and sustainable due to factors such as depletion, climate change, and emerging contaminants.
