food security africa

  • Young people have the advantage of having grown up in a globally connected world, within which we communicate more quickly and broadly than perhaps any other generation before us.
  • In my work at the Food, Agriculture and Natural Resources Policy Analysis Network (FANRPAN), one of my responsibilities is to help smallholder farmers adapt and create climate-resilient farming methods. Such knowledge exists but often fails to reach Africa's vast rural populations.
  • When I was a child growing up in Zimbabwe, my grandmother used to go to the same one-acre plot of land each day and work long and exhausting hours.  When I asked her why she put herself through this, she replied: "This is how I wake up every day, this is how I survive." I am now in my twenties and my grandmother is still out there on her plot each day. She continues to till her field with a hand hoe, using seed saved from previous harvests, and applying a teaspoonful of fertiliser per maize plant. Her working hours and type of inputs have remained the same over the years; however, the yields have been declining drastically.

      I'm learning more about food security right now, and in particular I'm wondering about is how to make more food at the same time as we did before. I was researching this question online, and this blog post caught my attention because the girl is sharing about her childhood in Zimbabwe, how to grow food. The expriences that she has is really interested me.

      I am currently learning about Africa's food security. I read this article "fighting for Africa's foo Security" by Sithembile Ndema. This article. Ms.Ndema speaks a bit about her child hood in Zimbabwe and how she would see her grandmother go to the same one acre plot of land each day, where she would work long hours growing crops. It is how she survived "This is how i wake up everyday, this is how i survive." " She continues to till her field with a hand hoe using seed saved from previous harvest, and applying a teaspoonful of fertiliser per maize plant. Her working hours and type if in outs have remained the same over the years, how ever, the yeilds have been declining drastically." The quote above is basically describing what sithembile's grandmother does. It also address the problem. " Yeilds have been declining drastically." I think this is a serious problem because this is how many people survive. It makes me wonder what other people can do to help. As i was reading this article i began to wonder how i will help this article also made me appreciate the many things that i have and the opportunity's that others do not

  • Yet today, in 2010, the effects of climate change are exacerbating an already vulnerable food supply in Africa, leaving farmers less capable of providing for themselves, let alone their communities. African farmers need to be able to access the knowledge and tools with which to grow a food-secure future for Africa. This would include, for example, the most effective and cost-efficient fertilisers and seeds, and improved access to markets.

      The quote I chose here is basically saying that the growth of food in Africa is still based on how good the climate is in now a days. The growth of food supply is not only one farmer's job, but all farmers's job. Everyone work together as a community and be success as a group.
  • While many young people do not seem to care about agriculture, they should acknowledge the fundamental role it plays in our lives.  Not only does it feed the cities, but it also feeds factories with the raw ingredients needed to continue building an economy.   One Young World will give me a chance to promote the importance of agriculture among my peers, and to help them understand its role in creating a food-secure, economically-stable Africa in the future.

      I this is challenging because the technology in now a days are very good, but we still need at least 5 years to improve the technology to make food supply faster and easier. It makes me wonder how can the technology imapct the farming.
  • Political instability, global poverty and health, the financial crisis, religious conflicts and climate change are all issues that affect us and require long-term solutions to address substantially.

    I'm learning more about Food Security right now, and in particular what I'm wondering about is: Is this a problem of politics or science? In other words can we right now "Young people have the advantage of having grown up in a globally connected world, within which we communicate more quickly and broadly than perhaps any other generation before us. Whilst young people may not yet have the power to drive policies, we will be the ones who must accept the big challenges of the future which are as yet unresolved: from population growth to climate change to market reform and the end of poverty."

    I'm learning more about food security right now and in particular what I'm wondering about is how the next generation will take over to fight the challenge. I was researching this question online and this article caught my attention because it was written by a 24 year old woman who has worked in the field all her life. She grew up in Zimbabwe and she used to watch her grandmother work long exhausting days as a child and even now. Because of her grandmother, she wants to make a difference as she attempts to get her generation more active in facing world problems.\n\n"Whilst young people may not yet have the power to drive policies, we will be the ones who must accept the big challenges of the future which are as yet unresolved: from population to climate change to market reform and the end of poverty."\n\nThe quote I chose here is basically saying that she is calling out to the younger generation for help. Even though we don't have as much power as many others, we still have the power to try. It's up to us to contribute to changing the world.\n\nI think this is strong and hopefully it will motivate the younger generation to volunteer more and acknowledge these world issues. It makes me wonder what will happen in the future when it comes to youth involvement in the world. Will youth voices slowly disappear? Will anyone care anymore?

    "Young people have the advantage of having grown up in a globally connected world, within which we communicate more quickly and broadly than perhaps any other generation before us." The quote I chose here is basically saying the younger generation can spread awareness because of the technology nowadays, news can be heard around the world. I think this is strong statement because it's true. That's how most people hear the news. Online, texting, watching television, and social networking. Many youngsters don't really read the newspaper. It's easier to just check the news websites online.

    I'm learning more about food security in Africa right now, and in particular what I'm wondering about is why is there such a huge food shortage in Africa? While i was researching this question online i found this blog, entitled " Fighting for Africa's food security" It caught my attention because it seemed like it would be interesting and that the answer to my question would be within this blog. I thought this because of the title it had the words food security in it which i know is related to hunger so, it caught my attention. "When I asked her why she put herself through this, she replied: "This is how I wake up every day, this is how I survive." I am now in my twenties and my grandmother is still out there on her plot each day. She continues to till her field with a hand hoe, using seed saved from previous harvests, and applying a teaspoonful of fertiliser per maize plant.

    I'm learning more about Fighting for Africa's food security right now , and in particular what I'm wondering about is how people work so hard? I was researching this question online, and this article caught my attention because it shows how people in Africa need help. "She continues to till her field with a hand hoe, using seed saved from previous harvests, and applying a teaspoonful of fertiliser per maize plant. Her working hours and type of inputs have remained the same over the years; however, the yields have been declining drastically. " This quote I chose here is basically saying how they wake up early and start to work so they can get something to eat. I think that this is strong because for them they have to work really hard to find food. Another quote that I liked was " "This is how I wake up every day, this is how I survive." I like this quote because it shows how they are willing to survive no matter what.

    "Yet today, in 2010, the effects of climate change are exacerbating an already vulnerable food supply in Africa, leaving farmers less capable of providing for themselves, let alone their communities. " Well right now I'm learning about Food Security and in particular what I'm wondering is that if the problem in climate change in Africa has to do with global warming. There has to be a reason why the climate changing is occurring in Africa.It probably all has to do with global warming. I think maybe that we humans are the ones who caused the decrease in food security. God doesn't that suck....

It's too bad that these type of things happen in other parts of the world. I feel so spoiled and bad compared to these people. I'm so lucky and blessed to have the life that I have and that things are sometimes just handed to me and that opportunities are everywhere. I hope these type of lives will one day be over so that everyone can live a wonderful and fruitful life instead of having a hard working life like this.

    I'm learning more about Africa's food security right now, and in particular what I'm wondering is: Why isn't the younger generation helping the older generation? I was researching this question online, and this news item caught my attention because, all the changes that they are talking about is going to affect them in the long run and if they don't something about it now then it would be harder to fix later. The title of the news article is Fighting For Africa's Food Security. Something that i saw in the summary was that they are trying to fix the problem with Africa and they are trying to make a better way to get the young generation involved since they are not involved at all. "Political instability, global poverty and health, the financial crisis, religious conflicts and climate change are all issues that affect us and require long-term solutions to address substantially." I think this is a strog description because, if peoplee don't worry the sudden changes now how are they going to fix them later. I think that fixing the problem now will be more easier because later if you try to fix it some obstacles might be in the way.

    I'm learning more about Food Security right now, and in particular what I'm wondering about is what else affects food security. I was researching this question online, and this blog post caught my attention because it said a bunch of other stuff that would affect food security. I chose this passage because it interests me to learn more about how other things contribute to food security. \n\n"Political instability, global poverty and health, the financial crisis, religious conflicts and climate change are all issues that affect us and require long-term solutions to address substantially."\n\nThe quote I chose here is basically saying that other things like political instability, climate changes, etc are also affecting food security in countries. \n\nI think this is true because it makes me wonder how governments or people who represent us would cause a big effect on food security. I also think that climate changes can cause the most effect on food security because it changes the weather and also causes the temperature to change all around the world. It also causes the world to have more natural disasters all around. Many people lives also changes as the weather around them change.

    I'm learning more about food security right now, and in particular what I'm wondering about is: How does food security affect Africa? I was researching this question online and this blog post was attached on one of the pages on www.urgentevoke.com. It caught my attention because in the urgent evoke game they made up a hypothetical situation of food security and I wanted to know about an actual one.\n\n"When I was a child growing up in Zimbabwe, my grandmother used to go to the same one-acre plot of land each day and work long and exhausting hours. When I asked her why she put herself through this, she replied: "This is how I wake up every day, this is how I survive."

"\n\nThe quote I chose here is basically saying that agriculture is the main source of food in Africa and the people have to work for their entire lives on crops and farming.\n\nI think this is interesting because people have to do a lot of hard labor. It makes me wonder why in the U.S. and other countries, people are able to retire after a certain age. But, in Africa they have to work their entire lives.

    I'm learning more about food security right now, and in particular what I'm wondering about is: Why is there food security? I was researching this question online and this news item caught my attention because it talks about the reasons why there are food shortages. "The effects of climate change are exacerbating an already vulnerable food supply in Africa, leaving farmers less capable of providing for themselves alone. let alone their communities." The quote i chose here is basically saying that due to global warming, and recent climate changes, crops are not growing as well as they could. As the heat, and cold gets worse plants will not be able to survive. I think this is will not be good for the economy because without farmers being able to grow crops, that means less food for the humanity. It makes me wonder how much longer, it will take before food runs out, and people starve to death. Will the scientists figure out a way for more heat-resistant plants?

Her working hours and type of inputs have remained the same over the years; however, the yields have been declining drastically."\n\nThe quote i chose here is basically saying that the girl who is mentioned in the quote works hard to plant her crops and take care of the crops to. Food security is important because she wants to be able to feed her family.\n\ni think this is interesting because It makes me wonder about how food security is in other places outside the United States.

    I'm learning more about Copenhagen conferences right now, and in particular what I'm wondering about is :''Why is the Copenhagen conferences so important? i was researching this question online,and this blog post caught my attention because the title of the blog is Obama's remake at the unit nation climate change conference,and i saw why this conference is important, because the people that join the conference is all the leadership of their country around the word. "Climate change will pose unacceptable risks to our security, our economies, and our planet. Climate change poses a grave and growing danger to our people" The quote i chose here is basically saying that the climate change is danger to the people. The climate change also will damage our security,our economies,and our planet. I think this is best because the conference it makes me wonder that the leadership of the world know the problem of this,so they just have a conference about the climate change,so they try to solve the climate problem,because it can be damage the world, so they try to decrease the pollution of the world ,some of their country cut the greenhouse gas emission, some of them cut the emission intensity. they do so hard to cut this,so i think it should have more conference like this, then they can make the world more better.

  • The most commonly discussed measure of global warming is the trend in globally averaged temperature near the Earth's surface.
    • Munaza EWSIS
      Munaza EWSIS on 09 Dec 09
       
      This is impotant, many people do not know that the temperature of the earth is cahnging significantly.
  • An increase in global temperature will cause sea levels to rise and will change the amount and pattern of precipitation, probably including expansion of subtropical deserts.[7] The continuing retreat of glaciers, permafrost and sea ice is expected, with warming being strongest in the Arctic. Other likely effects include increases in the intensity of extreme weather events, species extinctions, and changes in agricultural yields.
    • Munaza EWSIS
      Munaza EWSIS on 09 Dec 09
       
      The temperature is affecting not only regular temperature but also changes in the agriculture facilities. It is merans that food industry prices as well as food companies will "sky rocket", because of temperature changes.
  • Political and public debate continues regarding climate change, and what actions (if any) to take in response. The available options are mitigation to reduce further emissions; adaptation to reduce the damage caused by warming; and, more speculatively, geoengineering to reverse global warming. Most national governments have signed and ratified the Kyoto Protocol aimed at reducing greenhouse gas emissions.
    • Munaza EWSIS
      Munaza EWSIS on 09 Dec 09
       
      Politics is making the Climate Chnge issue, unimportant, I beleive that Govermnets are just "selling their image", so they would look good. There are many, many policies pacts that have been made in order to "control Clmiate Change/ Global Warming". When will there be a policy that actually help the meniviroment?

  • Human activity since the Industrial Revolution has increased the amount of greenhouse gases in the atmosphere, leading to increased radiative forcing from CO2, methane, tropospheric ozone, CFCs and nitrous oxide. The concentrations of CO2 and methane have increased by 36% and 148% respectively since the mid-1700s.[23] These levels are much higher than at any time during the last 650,000 years, the period for which reliable data has been extracted from ice cores.[24] Less direct geological evidence indicates that CO2 values this high were last seen about 20 million years ago.[25] Fossil fuel burning has produced about three-quarters of the increase in CO2 from human activity over the past 20 years. Most of the rest is due to land-use change, particularly deforestation.[26]

      Industrial Revolution was bound to happen, people would live in the stone age for the rest their lives. When the Industrial Revlotion did occur things did not look bad, as of 2002 and futher did the climate change was becoming a issue to looked upon as an issue.
  • If the atmosphere is warmed, the saturation vapor pressure increases, and the amount of water vapor in the atmosphere will tend to increase. Since water vapor is a greenhouse gas, the increase in water vapor content makes the atmosphere warm further; this warming causes the atmosphere to hold still more water vapor (a positive feedback), and so on until other processes stop the feedback loop
    • Munaza EWSIS
      Munaza EWSIS on 09 Dec 09
       
      The atmosphere is warming up, there is no way for stoppiong the warming up but there is a way of slowing this down or going green
  • When ice melts, land or open water takes its place. Both land and open water are on average less reflective than ice and thus absorb more solar radiation. This causes more warming, which in turn causes more melting, and this cycle continues.
    • Munaza EWSIS
      Munaza EWSIS on 09 Dec 09
       
      The Ice is melting. If you look at the The cold continent of Antartica, the ice caps are melting there. The North and the South Poles are melting. The sea levels are rising and inhabitants such as polar bears and Penguins are getting affected. The sea levels are afftecting Island Nations as well as sea bordering nations.
  • Global warming is the increase in the average temperature of the Earth's near-surface air and oceans since the mid-20th century and its projected continuation. Global surface temperature increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) between the start and the end of the 20th century.
    • Mei EWSIS
      Mei EWSIS on 09 Dec 09
       
      basic information about global warming.
  • However, warming is expected to continue beyond 2100 even if emissions stop, because of the large heat capacity of the oceans and the long lifetime of carbon dioxide in the atmosphere.
    • Mei EWSIS
      Mei EWSIS on 09 Dec 09
       
      people are using air conditioner in the summer and the gases come out of air conditioner are bad for the o-zone.
  • Temperature changes vary over the globe. Since 1979, land temperatures have increased about twice as fast as ocean temperatures (0.25 °C per decade against 0.13 °C per decade).
    • JackeyQ EWSIS
      JackeyQ EWSIS on 09 Dec 09
       
      I think this sentence is important because this shows that global warming is causing the earth to get warmer. This changes things lik melting of ice bergs which can lead to rising sea level and cause major changes.
  • The Intergovernmental Panel on Climate Change (IPCC) concludes that most of the observed temperature increase since the middle of the 20th century was caused by increasing concentrations of greenhouse gases resulting from human activity such as fossil fuel burning and deforestation.
    • JackeyQ EWSIS
      JackeyQ EWSIS on 09 Dec 09
       
      This is important because it descibes why and how the temperatures all around the world are going up. This also shows that as we get more technology, we are destroying the earth more and more.
  • The IPCC also concludes that variations in natural phenomena such as solar radiation and volcanoes produced most of the warming from pre-industrial times to 1950 and had a small cooling effect afterward.
  • The uncertainty in this estimate arises from the use of models with differing sensitivity to greenhouse gas concentrations and the use of differing estimates of future greenhouse gas emissions.
    • JackeyQ EWSIS
      JackeyQ EWSIS on 09 Dec 09
       
      I think this means that no one can predict what would happen or how much emissions we produce. Less is the best, but none is great
  • The greenhouse effect is the process by which absorption and emission of infrared radiation by gases in the atmosphere warm a planet's lower atmosphere and surface.
    • JackeyQ EWSIS
      JackeyQ EWSIS on 09 Dec 09
       
      This means that how much emissions we would make is how much global warming we create or how much we would make our own doom.
  • Clouds also affect the radiation balance, but they are composed of liquid water or ice and so are considered separately from water vapor and other gases.
    • JackeyQ EWSIS
      JackeyQ EWSIS on 09 Dec 09
       
      I wonder if this can also help since it can cool down the face of the earth and also it can help by reflecting solar light back into space as it makes it's way through the atmosphere.
  • Global dimming, a gradual reduction in the amount of global direct irradiance at the Earth's surface, has partially counteracted global warming from 1960 to the present.
    • JackeyQ EWSIS
      JackeyQ EWSIS on 09 Dec 09
       
      This means that global dimming helps by reflecting the warm sunlight away from earth so that we can keep it cool itstead of hot.
  • Observations show that temperatures in the stratosphere have been steady or cooling since 1979, when satellite measurements became available.
    • JackeyQ EWSIS
      JackeyQ EWSIS on 09 Dec 09
       
      I wonder if this can really help out since it has really little effect, while we release tons of gas into our atmosphere.
  • Warming is expected to change the distribution and type of clouds. Seen from below, clouds emit infrared radiation back to the surface, and so exert a warming effect; seen from above, clouds reflect sunlight and emit infrared radiation to space, and so exert a cooling effect.
    • JackeyQ EWSIS
      JackeyQ EWSIS on 09 Dec 09
       
      I think this is important since it might trap heat, but it relfects even more heat out than it traps. It also helps cool the earth, but trapping those gases in can harm us since those gas can be toxic.
  • Measures including water conservation,[99] water rationing, adaptive agricultural practices,[100] construction of flood defences,[101] Martian colonization,[102] changes to medical care,[103] and interventions to protect threatened species[104] have all been suggested. A wide-ranging study of the possible opportunities for adaptation of infrastructure has been published by the Institute of Mechanical Engineers.[
    • JackeyQ EWSIS
      JackeyQ EWSIS on 09 Dec 09
       
      I wonder if we would really need to evacuate earth if there is no possible answer for saving our lives and the earth as well.
  • Geoengineering is the deliberate modification of Earth's natural environment on a large scale to suit human needs.[106] An example is greenhouse gas remediation, which removes greenhouse gases from the atmosphere, usually through carbon sequestration techniques such as carbon dioxide air capture.
    • JackeyQ EWSIS
      JackeyQ EWSIS on 09 Dec 09
       
      I think this is important because if we do have to evacuate the earth, then we would need to bring this information to our new planet so that we can preserve that planet and hopefully learn from our mistakes.
  • In 2007–2008 Gallup Polls surveyed 127 countries. Over a third of the world's population were unaware of global warming, with developing countries less aware than developed, and Africa the least aware. Of those aware, Latin America leads in belief that temperature changes are a result of human activities while Africa, parts of Asia and the Middle East, and a few countries from the Former Soviet Union lead in the opposite belief.
  • Geoengineering is the deliberate modification of Earth's natural environment on a large scale to suit human needs.
    • JackeyQ EWSIS
      JackeyQ EWSIS on 15 Dec 09
       
      This means that geoengineering is the study of changing the environment of earth to suit human needs. This is like constructing more land or to shape the lands so that buildings can be built or changing the land so that it can be used for vegetation.
  • one study suggests that projected rates of extinction are uncertain.[80]

  • Members of the Farming First coalition believe that: Agriculture generally, and farmers especially, are vital to mitigate and adapt to climate change. Increasing farm productivity in a sustainable way and decreasing waste and losses can significantly mitigate the effects of climate change, prevent deforestation, and protect biodiversity. Adopting proven sustainable agricultural practices reduces greenhouse gas (GHG) emissions and enhances the effect of natural carbon sinks. Further research and innovation are essential to invent the necessary adaptation and mitigation solutions. Therefore, farmers must be involved in implementing climate change mitigation and adaptation strategies. To support them, we must create sound and reliable incentives; we must share knowledge; and we must make adequate tools and technologies accessible to deliver both food and energy security. As key stakeholders in agriculture, the world’s farmers, agronomists, scientists, engineers and industries are working together through an open coalition, to provide innovative solutions which reduce emissions from agriculture and adapt to climate change while increasing agricultural productivity to meet growing food needs.

    its good that we are haveing more knowledge to get world hungary over with because i though that they are really bad when they have alot of food shortage speically in the desert parts there is like no way that they can grow food but with our powers now i think that we can actually grow food at places liek that which can help them which is great. i though that it's great in many ways because with this i thin k that they can help them solve thier thing

    I'm learning more about food security right now, and in particular what I'm wondering about is how to reduce the chance of food insecurity and get a better way to produce more food. I was researching this question online, and this blog post, "Climate/Farming First" caught my attention because it answered my question and listed a lot of useful sources of ways. The quote I chose here is basically saying that the change of the climate affects the amount and quality of agricultural production directly. For example, greenhouse gas emission would affect the quality of the production or even reduce the amount of it. As a result, professors in various fields from all over the world tried to do research and explore ways to solve this problem. I think this is very amazing because I didn't know that the surroundings would also affect the agriculture production, which might lead to great food insecurity. It makes me wonder whether the experts have thought of good ways to solve the issue. I'm also wondering if I would also be able to contribute to their research in the future.

  • A comforting thought, except for one thing: it's not true. A study published in the Jan. 9 issue of Science shows that far from compensating for the damages associated with climate change (heavier and more frequent storms, increasing desertification, sea-level rise), hotter temperatures will seriously diminish the world's ability to feed itself.

    "It can be difficult in the middle of winter - especially if you live in the frigid Northeastern U.S., as I do - to remain convinced that global warming will be such a bad thing. Beyond the fact that people prefer warmth to cold, there's a reason the world's population is clustered in the Tropics and subtropics: warmer climates usually mean longer and richer growing seasons. So it's easy to imagine that on a warmer globe, the damage inflicted by more frequent and severe heat waves would be balanced by the agricultural benefits of warmer temperatures." im learning more about this because i jsut finshed reading this i though that this is a good thing and a bad thing becuase i saw it on netgeo that if the earth temptrue go up by 1 or 2 is a major change in the earth it can affect alot of differet things however since global warming gets warmer it means that there will be easyier to grow food however if it keeps on getting hotter is going to be really bad im sure so i guess we need to stp this becuase it's jsut simply bad. in many different ways we are doing this as as a bookmark to show that we did some work and i thought that this article is really cool

    I'm learning more about how global warming is causing a food crisis all over the world right now and in particular what I'm wondering about is: what is going to happen if nothing is done? I was researching this question online and this article caught my attention because it describes what might happen in the future by providing statistics and evidence. \n\n"In Italy, maize yields fell 36% in 2003, compared with the previous year, and in France they fell 30%. Similar effects were seen during a major heat wave in 1972, which decimated farms in the former Soviet Union, helping push grain prices to worryingly high levels. If those trends hold in the future, the researchers estimate that half the world's population could face a climate-induced food crisis by 2100."\n\nThe quote I chose here is basically saying that global warming is already affecting many countries. We can also see that it has greatly affected us in the past as well. If further actions are not taken, we might all be in a really bad situation the coming years.\n\nI think this is very alarming because it states strong evidence that global warming is affecting agriculture and food production. It makes me wonder what will happen in the future. Will the world be in a climate-induced food crisis by 2100? But, even with all the talks about trying to change the situation, I don't see much change and impact on society. People are procrastinating and not taking this issue seriously. Maybe we'll all just die.

    I totally disagree with this statement. Yes, people may enjoy warmer weather and "It can be difficult in the middle of winter - especially if you live in the frigid Northeastern U.S., as I do - to remain convinced that global warming will be such a bad thing. Beyond the fact that people prefer warmth to cold, there's a reason the world's population is clustered in the Tropics and subtropics: warmer climates usually mean longer and richer growing seasons.

    "With these frightening predictions in mind, we need to try to heat-proof our agriculture. That can be accomplished by using crops that have proved resistant to extreme heat - like sorghum or millet - to breed hybrid-crop varieties that are more capable of withstanding higher temperatures. We'll need to drop any squeamishness about consuming genetically modified crops. Unless we can tap the power of genetics, we'll never feed ourselves in a warmer world. But we'll need to act quickly. It can take years to breed more heat-resistant species, and investment in agricultural research has shriveled in recent years." This is a great way to get ideas going to test what can work and what won't work in these tough times. We have to figure out ways to continue growing crops through these harsh and terrible weather conditions. We have to be smart and conduct new ways. We need this. Really badly. Its the only way we can help the starving people around the world and how we can help farmers make good money in more than one season.

    I'm learning more about food security right now,and in particular what I'm wondering about is:why global warning portends a food Crisis?I was researching this question online,and this blog post caught my attention because it have told what will happen in Africa. "Yet many climatologists believe that global warming will make dry areas dryer and further damage farming, which is especially dire news for sub-Saharan Africa, a region that already struggles with heat waves, droughts and famines even as population continues to grow. "Climate change is going to be a major concern for Africa," says Nteranya Sanginga, director of the Tropical Soil Biology and Fertility Institute of the International Center for Tropical Agriculture in Nairobi. "We could lose whole growing seasons."" The quote I chose here is basically saying that the Africa will lose the whole growing season,because the temperature in Africa have the higher temperature effect by the Battisti and Naylor ,it is not the possible effect of changing precipitation patterns.The climatologists believe that global warning will make the dry areas dryer and further damage farming.It make the climate is changing is going be a major concern for Africa. I think this is amazing because it makes me wonder that there have so many country don't have enough food for their people,and because the climate change,make some place can't grow the plants again,so i think if you want solve the problem of the food security, one of the thing you need to do is solve the global warning,make it don't not effect the climate.

    I'm learning more about "food security" right now, and in particular what I'm wondering about is: what really caused this problem. I was researching this question online, and this article, "Why Globing Warming Portends a Food Crisis" caught my attention because it made me realize the connection between two big global issues. The quote I chose here is basically saying as the temperatures on this planet becomes higher and higher, more and more food is going to be damaged. I think this is really serious because we all would die without food. It makes me wonder what would happen if the temperatures keep going up and causing more serious food security issue. I hope there would be a way to solve these problems.

    I'm learning about "We need to realize Africa's potential on agriculture" right now, and in particular what I'm wondering is African farmers must be able to access the knowledge and tools they need to unleash agriculture's full potential for the continent? I was researching this question online, and this article caught my attention because it talks about the threat of food insecurity, of a changing climate, of disrupted marketplaces all paint a picture of potential famine, drought and widespread poverty. "Climate change is exacerbating an already poor food supply in Africa, leaving farmers less capable of providing for themselves, let alone their communities. The problems vary across the continent - droughts, flash floods, early rains, late frosts - but they all threaten to make farmers' traditional planting knowledge obsolete. A recent report from the International Food Policy Research Institute (IFPRI) projects that wheat, rice and maize yields in sub-Saharan Africa are expected to drop by 34%, 15% and 10% respectively by 2050." The quote that I chose here is basically saying that climate is something important because that determines the food. I think that this is strong because people need food to survive. Without food they are dead.

    "Wildland fires are part of a feedback loop that relates to global climate change. When trees and grasses burn, they release carbon dioxide, thus adding to the greenhouse effect and raising the risk of future heat-stoked wildfires." This is very interesting to read. Given the effects previous wildfires occur and with droughts happening the risk is even higher for wildfires to begin and start. Predicting when they would happen I guess is hard to say but at least we can figure out WHERE it would happen next i suppose. "Where drought does strike, the risk of wildland fire soars. NCAR takes a multidisciplinary approach to address this concern. "

    I'm learning more about Global Warming right now, and in particular what I'm wondering is will we have to live underwater in the future? I was researching this question online, and this blog post caught my attention because many things are changing around the world. Disasters like hurricanes grow stronger and other things like drought become longer and deadlier. Few challenges facing America-and the world-are more urgent than combating climate change. The science is beyond dispute and the facts are clear. Sea levels are rising. Coastlines are shrinking. We've seen record drought, spreading famine, and storms that are growing stronger with each passing hurricane season. The quote here is basically saying that our continents are sinking into the sea or is getting swallowed by the sea. Things like hurricanes grow stronger from this and other disasters also grow deadlier. I think this is scary because one year your house might be right next to the coast line and the next year, right when you step out of your backyard, your stepping on ocean water. This makes me think will we have to live underwater in the future and adopt to underwater conditions.

Do you ever sneeze right after eating a meal? where there is exposure to some bright light, I will always sneeze. Does your heart really stop when you sneeze? (literally) to sneeze.

    Something that I have been interested in learning more about has been about Environment. I remember my Math Teacher talking about it during his math class, but I didn't have a good explanation on what he really meant. Lately, the issue had caught my eye again. I know that many people feel that why is the environment important to the world and us? From what I have heard many scientist say that we need to have the environment clean. For example I hread that if we dont keep the environment clean we are destryoing ourselves. Now that's what I have heard, it may or may not be true. On thing that I know for sure about Environment is that it's what we live in and we need to make the best of it. Now I've studied my share of Biology and I believe that the Environment is caused by the smokes and other stuff that damages the world. Personally that's what I know and it may sound kind of funny but hey that's what ever one says. The most important about this topic is that Environment is what it keeps us on this world. An important quote that I believe that is given alot of information is where it says: Be the change you want to see in the world, said former UCL student Mahatma Gandhi - and staff at the UCL Environment Institute are acting on his advice.Staff calculated the carbon footprint of their work-related travel as part of an ongoing attempt to reduce the institute's impact on the environment.The study was based on the movements of a total of 12 staff and three PhD students during the 2007/08 academic year.The staff based their calculations on guidelines from the Department for the Environment, Food and Rural Affairs (DEFRA).They used the guidelines to calculate precisely how much carbon was emitted in the course of their work-related travel. According to the article :: The total carbon dioxide emissions for staff in 2007/08 amounted to 29.64 tonnes as a result of 231,700 kilometres of travel - an average of 2.5 tonnes per person.
