Food is a basic human necessity yet millions of people around the world go hungry every day. Food insecurity is a problem which afflicts many countries throughout the world. Achieving food security is highly critical to poverty alleviation. Health, education, ability to work productively (economic decline) and overall quality of life are affected by food insecurity. Climate change further exacerbates the threat of food insecurity.

Food security situation in which all people, at all times, have physical, social and economic access to safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life. This depends on the availability, access and biological utilization of food. (World Food Summit 1996) Climate change refers to any significant change in the weather or distribution of weather events over an extended period. This includes major changes in temperature, rainfall, wind patterns, precipitation. The impacts of climate change food security may be felt primarily through changes in crop yields, water availability, pests and diseases and animal health (terrestrial and aquatic)

The threat that climate changes pose to agricultural sector is alarming. The increased frequency and extent of floods, droughts and land erosion has rendered the agriculture sector more vulnerable and reduced the productivity of land and the potential for plant production. Although increases in temperature and carbon dioxide can be very beneficial to (some) crops, other impacts from global warming could counteract the effects reducing overall yield.

Excess soil moisture, in addition to direct flood damage, is a major component of crop losses due to extreme precipitation events. Heavy rainfall washes away vital nutrients in the soil. Many weeds, pests and fungi thrive under warmer temperatures, wetter climates, and increased CO2 levels. Farmers…...

...Climate Change Climate change is a long-term alteration in the statistical distribution of weather pattern over periods ranging from decades to millions of years. The world is currently experiencing drastic change in temperature. This change can be felt in the tropical climate areas where the weather is getting hotter and hotter every day. The change in global temperatures and precipitation over time is due to natural variability or to human activity. It is also caused by accumulation of greenhouse effects (Arrhenius, 1896). Should we as humans let this problem worsen? Climate change will affect everything including humans, flora and fauna, and the environment. One of the effects of climate change is how it will affect the people. Climate change will have a huge impact on the people’s health. The health of the people will be affected mostly by air pollution and respiratory problems will have the greatest risk of health effects. Increases in moulds and pollens due to warmer temperatures could also cause respiratory problems such as asthma for some people. Should the effects of climate change get any worse than what it is now, people around the world will have to face some serious problems. Food security will be affected and thus diseases can easily get transmitted. Food or waterborne diseases are acquired through eating or drinking. For example, Hepatitis A is a viral disease that interferes with the functioning of the liver. It can be spread through consumption of food or......

How Climate Changes Have Effected Human Evolution

...How Climate Changes Have Affected Human Evolution Abstract This paper explores the link that changing climates and human evolution share. As climates change in the world then all living things must adapt accordingly or become extinct. I will go over some examples on how lifestyle changes were necessary for survival when climate these changes occur. 1 Climate changes can be seen around the world on a daily basis. No matter where you go you can hear somebody say the old phrase, just wait five minutes and the weather will change. Climate changes have been happening since the beginning of time and are not going to stop anytime soon. As human beings we have to adjust to the climate changes because the climate definitely is not going to adjust to us. In the article I decided review it talked about is how the climate has affected how humans have evolved. All kinds of climate changes can affect how humans and animal live on a daily basis. The article stated something that really made me stop and think. It said that when change happens, animals have a choice to either keep doing what they are doing now, become extinct, or change to adapt to the new way of life. (Smithsonian National Museum of Natural History. N.D.). This was so simply stated but encompasses everything about evolution. With all the climate changes in climate, even today, we are going to have to change the way we live in the future or eventually become extinct. ...

...CLIMATE CHANGE ADAPTATION PROJECT Climate change is the change in stable weather conditions of a given place which have been noted in such a place for a period extending over thirty years. It is notable and lasting change in the distribution of weather patterns in over thirty years. Climate affects agricultural production directly. The International Fund for Agricultural Development accepts climate change to be among the factors influencing rural poverty. Climate change affects the globe as a whole but its effects is felt much more by poor people in third world countries because they rely much on natural resources as a source of their livelihoods. Poor rural communities rely much on livestock keeping and agriculture which are climate-sensitive sectors of the economy. We have to adapt and employ mitigation strategies to respond to climate change. Adapting involves reducing the vulnerabilities of ecosystem to climate change whereas mitigation involves reducing the long term impact of climate change. Mitigating also involves reducing the emission of green house gases while adapting will also involves supporting local communities to deal with the impacts of climate. Agriculture of a given place depends on the climate of such a place; with climate change agriculture is affected negatively. Climate change accelerates the challenges facing the agricultural production and specifically in Sub-Saharan Africa. Innovations are the way to mitigating the effects of climate change on......

...CLIMATE CHANGING AND THE EFFECT IT HAS ON YOU Dijonne King PSC 140 December 1, 2013 Climate change is the climate patterns attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. Climate change has recently become a huge issue here on Earth. The use of fossil fuels has largely affected the world as we see it today. Temperatures are rising, snow and rainfall patterns are shifting and extreme climate events such as heavy rainstorms and record high temperatures are highly affecting our environment. Through evidence of this climate change, scientists have come to realize the causes and effects of climate change. Through learning about what creates climate change, learning how climate change impacts you, and taking action, I believe climate change can definitely have a positive impact on everyone. Through scientific evident it is clear that climate change has affected the planet Earth as we know it. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives. The average temperature at the surface of the Earth has been increasing over the past century, mostly due to human activities. Warmer surface temperatures lead to increasing evaporation from the ocean and land, leading to an increase in global precipitation. Scientific studies have shown that extreme weather is more likely to become more intense with time. Human activities......

How Are Urban Areas Planning for Climate Change

...Urban areas planning for climate change Climate change changes the world’s weather patterns so not only do cities need to focus on reducing greenhouse gas emissions but to also adapt to future climate change and extremes of weather such as flooding and drought. I will be focusing on how the city of London in England is planning for climate change. 1. Greening London The government aims to increase the number of open and green spaces in London which not only improves the look and feel of the city, making it more attractive whilst reducing the impact of noise and air pollution. Greening London also makes the city more resilient to flooding and extreme weather events, and can contribute to a healthy mind and body. The Mayor aims to increase tree cover by five per cent by 2025, therefore achieving one tree for every Londoner and creating a better network of interlinked, multi-functional and high quality open and green spaces. 2. Cleaner air for London Air pollution is a serious health issue which damages the natural and built environment. Actions being taken to improve air quality include introducing the first ever age limit for black cabs tougher standards for the Low Emission Zone, new cleaner hybrid and hydrogen buses and fitting older buses with equipment including filters to curb pollution. The new bus for London, which will be launched in 2012, will use the latest green technology making it 40 per cent more efficient than a conventional double decker. The Mayor......

Impact of Climate Change on Food Security

...Abstract Climate Change is a global problem that is creating regional impacts to food security. Climate studies require the analysis of vast pools of data that are more easily processed by filtering down to the micro-climates or sub-climates of particular regions. Many studies have been completed utilizing global climate observations in an attempt to model changes to regional food production zones. Private organizations or government grant making groups with an interest in how climate change will directly impact their particular food security have funded most of the research available on this topic. Much of the literature available indicates that economically secure countries are more equipped to handle the food security impacts of climate change and have dedicated fewer resources to studying this issue. Three regions that have completed significant climate studies in relation to food security are Eurasia, Sub-Saharan Africa (SSA) and Australia (to include the Pacific island nations). All three regions discuss the use of Genetically Modified Organisms (GMOs) to address their food security concerns. The Impact of Climate Change on Food Security Climate change presents a multitude of potentially dangerous issues for world communities to solve. Perhaps the largest of these issues is the impact of climate change on food security. T. Thamizhvanan and K. Balaguru (2012) indicate that food security has four dimensions: “availability, accessibility, food utilization,...

Impact of Climate Change on Food Security in East Africa

...brief history about president of Uganda Yoweri Kaguta Museveni,is that he was elected or came into power in 1986 under the party called “National Movement Resistance” as the president of the party and till now he is the president of Uganda. Therefore,the main steps/strategies that the state in particular Museven`s regime has used in reorganizing Uganda in the last 3 decades are as follow; Restoration of peace in Uganda,this strategy was to bring an end to the Lords Resistance Army[LRA] threat in northern Uganda and the surrounding regions like Eastern Uganda ,the peace strategy must shift from one that develop leverage through military planning,tries to press Kony to make a choice about his future and pushes forward a development and security strategy that enables northern Ugandans to return voluntarily,where he tried to sign a peace talk with Joseph Kony but failed which made him to chase Kony outside Uganda hence one of the strategy. Political liberalization, generally liberalization can be referred to as the relaxation of previous government restriction usually in such areas of political liberalization can be defined defined as increasing citizen rights and liberties. Under Museveni`s regime ,Uganda has been implementing simultaneous political reforms since 1986,where the citizens have the rights and liberties in doing things especially in political issues especially freedoms of speech and many others hence one of the steps or strategies that state in particular......

... Impacts Of Climate Change IN Bangladesh | Group 2 | Members-Sakib Shahriar-1510119630 | Israt Jahan-1510581630 | Joyeeta Fabliha Zahir-Faisal Ahmed Shajal-Ashrafun Zamam Lima-Kazi Pushpita- | | Faculty-MRL ENV-107 | [Pick the date] | | Abstract Climate change is one of the most important issues to tackle this generation and possibly any generation in history. Bangladesh is likely to be one of the most vulnerable countries in the world to climate change. This paper discusses the possible impacts of climate change in Bangladesh through tropical cyclones, storm surges, coastal erosion and back water effect. Both qualitative and quantitative discussions are made on cyclone intensity increase for a sea surface temperature rise of 2 and 4°C. Different scenarios of storm surges under different climate change conditions are developed by using a numerical model of storm surges for the Bay of Bengal. Possible loss of land through beach erosion due to sea level rise on the eastern coast of Bangladesh is examined. Finally a few remarks are made on the adaptation options for Bangladesh in the event of climate change. Introduction Climate change is the biggest global health threat of the 21st century and is increasingly recognized as a public health priority. Bangladesh is recognized as one of the most vulnerable countries to climate change impacts in the world. It has a history of extreme climatic events claiming millions......

...Climate Change: Is Global Warming To Blame? Climate change is a serious reason for concern, because it affects every person living on the planet. The vast majority of the scientific community claims that anthropogenic global warming is to blame for these changes. However, there are a small number of people who deny the very existence of global warming. Their words carry a certain amount of weight in some circles, but they lack scientific proof to support these arguments. The effects of climate change are undeniable. Research conducted by the Intergovernmental Panel on Climate Change (IPCC) and other reputed meteorological institutions proves that average yearly temperature has been steadily growing over the last decades. The sea levels have also been rising, and the number of floods in different parts of the world has increased dramatically. Glaciers in the Northern Hemisphere have started to melt. This caused more icebergs to drift into the ocean. They currently pose a serious threat to both, cruise and cargo ships that course through the waters of the northern regions. There are reports of some icebergs being spotted far to the South from Greenland. Over 95% of scientists agree that these changes are caused by the “greenhouse effect”. There is some solid evidence which proves that people are directly responsible for the global warming that is fueling this climate change. Destruction of forests, burning of fossil fuels and environmental pollution are the main......

Climate Change

...Climate includes patterns of temperature, precipitation, humidity, wind and seasons. "Climate change" affects more than just a change in the weather, it refers to seasonal changes over a long period of time. These climate patterns play a fundamental role in shaping natural ecosystems, and the human economies and cultures that depend on them. Because so many systems are tied to climate, a change in climate can affect many related aspects of where and how people, plants and animals live, such as food production, availability and use of water, and health risks. For example, a change in the usual timing of rains or temperatures can affect when plants bloom and set fruit, when insects hatch or when streams are their fullest. This can affect historically synchronized pollination of crops, food for migrating birds, spawning of fish, water supplies for drinking and irrigation, forest health, and more. Some short-term climate variation is normal, but longer-term trends now indicate a changing climate. A year or two of an extreme change in temperature or other condition doesn’t mean a climate change trend has been "erased.” Worldwide, people are paying serious attention to climate change. In Washington state, climate change is already disrupting our environment, economy and communities. We can help slow it down, but we must take action now. source: http://www.ecy.wa.gov/climatechange/whatis.htm My reaction Since elementary days , maybe, some of you like me, always heard......

...Climate Change; "Greatest Challenge of our Time*"_ (Copenhagen Accord, March,2010) We still have to think of more solutions and new ways of dealing with this problem...... See, the climate change we are dealing with now, isn’t the same as was at the 1992 United Nations Framework Convention on Climate Change (UNFCCC) or at the 1997 Kyoto Protocol. Populations have grown, costs of living gone up, and more challenges emerged especially in a lot of developing countries. It is 2015 and we cannot just sit in round tables and talk of climate change in isolation. It is climate change and….. climate change and “I am hungry”, climate change and “I do not understand these strange new pests and insects on my farm”, climate change and “I have to do whatever it takes to take myself to the hospital, climate change and “can I afford to send my child to school” And steadily developing countries are rising to become huge contributors to a lot of environmental problems. And one cannot solely put the blame on people because; a lot of the actions leading to environmental damage are done unconsciously. One needs to survive_ fetch firewood for cooking, cut down some trees to get some more land to grow food/put up shelters to live in etc.…. And this should tell our governments, policy makers and all engaged in environmental protection and the fight against climate change that we still need to go back to the drawing board. Develop projects that address people’s basic needs; improve......

...The way that humanity reacts to climate change may do more damage to many areas of the planet than climate change itself, says a new study published in Conservation Letters by Conservation International's Will Turner and a group of other leading scientists. The paper "Climate change: helping nature survive the human response," looks at efforts to both reduce emissions of greenhouse gases and potential action that could be taken by people to adapt to a changed climate and assesses the potential impact that these could have on global ecosystems. In particular it notes that one fifth of the world's remaining tropical forests lie within 50 kilometers of human populations that could be inundated if sea levels rise by 1 meter. These forests would make attractive sources of fuel-wood, building materials, food and other key resources and would be likely to attract a population forced to migrate by rising sea levels. About half of all Alliance for Zero Extinction sites -- which contain the last surviving members of certain species -- are also in these zones. "There are numerous studies looking at the impacts of climate change on biodiversity, but very little time has been taken to consider what our responses to climate change might do to the planet, " Turner said. The paper notes that efforts to reduce greenhouse gas emissions by constructing dams for hydropower generation can cause substantial damage to key freshwater ecosystems as well as to the flora and fauna in......
