R9972 Geography Resource 31/1/08 7:18 AM Page 2 Meet the Mwangi Family Below is a picture of some members of the Mwangi family, who live in Kenya, Africa. Like most Kenyans, they live in the countryside and depend mostly on farming for a living. Outside of farming, there is little employment in the rural areas of Kenya. Some family members have therefore migrated to Nairobi, which is Kenya’s capital city. Father: Samuel Samuel owns the family’s six-acre farm. He is now 60 years old. He is a hard worker and a skilled farmer. By the clever use of irrigation (see Fact File 1) he manages to grow maize and beans, which make up the family’s staple diet. He also grows cash crops, such as onions and snow peas, which are sold at the local market. Some of these cash crops are bought cheaply by middlemen who then sell them on to exporters at greatly increased prices. Trócaire is helping farmers such as Samuel to organise themselves in cooperative groups that will by-pass the middlemen and sell their produce directly to the exporters. Mother: Shelmilh Shelmilh is 50 years old. She and Samuel have 8 children aged between 29 and 6, three of whom still live on the family farm. Like most African women, Shelmilh works very hard. It is her duty to cook, to repair the house and keep it tidy, to care for the children, to help to water and weed the crops, to tend to the farm animals and to milk the cows. Shelmilh also prepares food to sell to construction workers who work on a nearby road. The money she earns is spent on the home. An outline of Shelmilh’s workday is given in Fact File 2. 2 Fact File 1: Samuel’s Pan Samuel dug a pond that enables him to bring water to the crops on his farm. This pond is called a pan and it serves to collect rainwater. A hosepipe from the pan carries water to ‘drip irrigate’ the Mwangis’ crops. The pipe has many tiny holes in it, which allows water to drip slowly onto the ground where the crops are. The crops are cleverly planted in little hollows that prevent the irrigation water from seeping away. Samuel is full of ideas and plans. He hopes to expand his pan to such a degree that he could set up a small fish farm in his land. Fish would provide food security for his family and would be a source of income. But Samuel’s plans, and even the survival of his family, are now under threat. Global warming, for which developed countries such as Ireland are largely responsible, now threatens the Mwangi farm and many parts of Africa with potentially deadly droughts. R9972 Geography Resource 31/1/08 7:18 AM Page 3 Son: Morris (15) Daughter: Nancy (14) Morris attends Mirera Primary School (see Fact File 3). He wants to be a farmer like his father. He is a good distance runner and practices by running 14 kilometres three days a week. Morris would love to become a top athlete like so many of Kenya’s famous runners. He would also like to make friends with young people in Ireland. Nancy and Morris share the same class at school. Nancy enjoys school and studies hard. Each day after school, she helps her father on the farm and her mother with the housework. She would like to become a high school teacher. Grandson: Dan (5) Dan’s mother (who is a daughter of Samuel and Shelmilh) now lives and works in Nairobi. Dan is clever at school and wants to be a headmaster when he grows up! Son: Ian (6) Ian also attends Mirera Primary School. He loves to play soccer and other games with Dan and with other children. Fact File 2: Shelmilh’s Day 5am • Rise. • Make tea to sell to construction workers on the nearby road. • Prepare breakfast (tea with milk) for family members. 7am • Wash clothes, repair or tidy the house or do other household tasks • Prepare fodder (food) for farm animals. Feed and tend to the animals* 11am • Prepare lunch (usually boiled and fried maize with beans) to sell to construction workers at 20 Kenyan Shillings (ksh) per plate. Twenty ksh (which is the equivalent of about 20 cent) would buy two bars of soap or enough kerosene to keep the household lamp going for one day. 2pm • Work on the farm, Fact File 3: Mirera Primary School Mirera Primary School is a 1.5 kilometre walk from the Mwangi home. The school has 300 pupils, eight teachers and eight classrooms. The school is open from 7am to 4.30 pm (7am to 3pm for junior pupils). The subjects taught are Maths, Kiswahili (an African language), English, Science, Social Studies and Religious Education. An important thing about the school is that it can provide its students with clean water. Rainwater is trapped on the roof and is carried from there by pipes into large plastic storage tanks. When there is not enough rain to fill the tanks, students must bring their own water to school. During times of drought, many students do not attend school at all because they must move with their families to water sources further away. ✎ weeding and watering the crops, then milk the cows. 4.30pm • Prepare dinner for the family 7pm • After dinner: wash the dishes, tidy the house and plan the next day’s work. 8.30pm • Go to bed * The farm animals consist of two cows, a baby bull, three chickens and some baby chicks. The Mwangis used to have goats and sheep, but they were stolen by thieves who raided the Mwangi farm three years ago. Do Activity One on Page 8! 3 R9972 Geography Resource 31/1/08 7:18 AM Page 4 Water and Drought in Kenya Ireland Kenya Water is one of the world’s most precious resources. We need it to drink, to grow crops, to rear animals and to keep ourselves clean and healthy. Clean water is therefore a basic human need and human right. Furthermore, without water our planet would contain no animal or plant life. Water is life! It is easy for people in Ireland to forget how vital water is to our existence. We live in an economically developed country with a maritime climate where rainfall is frequent and where seemingly endless supplies of water require no more than the twist or movement of a tap. People in developing countries such as Kenya place a high value on access to water. The Kenyan climate does not provide rainfall all through the year. You will see from the graph that Kenya has two rainy seasons only. Most Kenyans rely on agriculture for their livelihoods. They have always relied on the rainy seasons to harvest two crops a year and to rear livestock. Rainfall figures for a weather station in Ireland and in Kenya. 1. Identify the month of maximum rainfall and of minimum rainfall in the Kenyan station and give the rainfall figures for each of these months. 2. Identify one main contrast between rainfall distribution in Ireland and Kenya. 3. What problem might Kenya’s rainfall distribution present for agriculture? In recent years, there have been very worrying changes in Kenya’s rainfall patterns. Rainfall amounts have declined seriously. The rains of March-April have now dwindled so much that they no longer always support a harvest or even the rearing of livestock. Meanwhile, the number of rainy days during the October to January period has now shrunk from nearly 60 to about 30. To make matters worse, the times of rainfall are now much less predictable than they used to be. Farmers are no longer sure when to sow their crops and valuable seeds are often lost when rain fails to come at its expected season. A drought is an unusually long period of insufficient rainfall. Drought has increased fourfold in parts of Kenya over the past twenty years. It can bring untold hardship to families such as the Mwangi family that you have read about on pages 2 and 3. 4 Periods of drought may cause harvests to fail. When harvests fail, food becomes scarce and food prices rise dramatically. Millet is a cereal that is used for making porridge. During times of scarcity, the cost of one kilogram of millet has risen from 15 to 100 Kenyan shillings. The cost of a kilo of beans has risen from about 2000 to nearly 5000 shillings. Increased food prices such as these make it very difficult for poor people to buy food. Long term drought can therefore lead to malnutrition among the poor. R9972 Geography Resource 31/1/08 7:18 AM Page 5 The actions or ‘coping mechanisms’ that farmers take to respond to the above problems often make the overall situation even worse: O Some people cut down trees to make charcoal from wood. They then sell the charcoal and buy food. But when trees are removed, the soil is less able to retain moisture. This leads to drier soil, to soil erosion and therefore to even more crop failures. Tho mas the water carrier Thomas Ledula is an eight year old Kenyan boy. Each day after school, he walks from his house to the nearest river to fetch water for his mother. O Some men leave their farms and go to other areas in search of work. Their farms may become neglected and even less likely to produce food. O Farmers sometimes sell their cattle with the intention of replacing them when a drought has passed. But rainfall is now so poor and unreliable that some farmers are afraid to restock their farms. Such farmers end up with less food than ever before. The above three ‘coping mechanisms’ helped Kenyan farmers to survive seasonal droughts in the past. But as droughts become more severe and rainfall becomes more erratic, these traditional ‘coping mechanisms’ now merely add to a vicious cycle of falling food supplies, poverty and malnutrition. Consider the following facts: • The river is 1.5 kilometres from the Ledula’s home. • The can Thomas uses to collect the water in carries 10 litres. • There are 8 people in the Ledula family • Each person needs at least 5 litres of water a day for cooking and drinking alone. (To stay healthy and clean, a person would need five times that amount of water). ³ IMAGINE that Thomas was asked to collect the water needed to supply only the cooking and drinking needs of all his family: How many times would Thomas need to go to the river each day to fetch this amount of water? How many kilometres in total would Thomas have to walk each day to fetch this water? If Thomas walked at an average rate of 3 kilometres an hour, for how many hours would he need to walk each day to fetch this water? DISCUSS the following questions: Farming in Africa (a) How does this farm scene differ from a typical Irish farm scene? (b) Describe how drought might affect the lives of these farmers. ✎ (i) Women and children traditionally fetch water in Kenya. How might this work affect their lives?

Do Activity two on Page 8! 5 R9972 Geography Resource 31/1/08 7:18 AM Page 6 Global Warming a great challenge of our time We have seen on pages 4 and 5 how drought is increasingly affecting the lives of people in Kenya. Drought now harms tens of millions of people in the Developing World. Scientists fear that its affects are likely to become progressively worse throughout this century. Can it be that we in economically developed countries such as Ireland are contributing to the misery of drought in countries such as Kenya? The answer, unfortunately, appears to be ‘yes’. Scientific studies show that global warming increases Developing World drought. It is virtually certain that global warming is being caused by human activities that are taking place especially in economically developed countries. How Global Warming Happens The sun heats the earth with short-wave radiation that passes easily through the atmosphere. The earth then sends out long-wave radiation, some of which remains in and heats our atmosphere. This is called the Greenhouse Effect. It is entirely natural and provides the heat we need for plants, animals and people to survive. The problem is that ‘greenhouse gases’ such as Carbon Dioxide are now increasing in our atmosphere, are trapping more and more long-wave radiation and so are causing global warming. The build-up of greenhouse gases is being caused by human activities and is triggering the climate to change. This is a huge threat to our planet. ´ 6 Examine the news article entitled ‘On Global Warming’ (Page 7) and answer or discuss the answers to the questions that follow: (a) What do the letters IPCC stand for? Write three factual points about the IPCC. (b) Describe two signs of the existence of global warming. (c) Describe in detail some causes of global warming that are mentioned in this article.

R9972 Geography Resource 31/1/08 7:18 AM Page 7 On Global Warming Global warming is no ‘theory’. It is an ‘unequivocal’ fact according to a 2007 finding of the United Nations’ IPCC or Intergovernmental Panel on Climate Change. The IPCC is an expert body that represents 130 nations. It has received the Nobel Peace Prize for its specialist investigations of global warming, for which it draws on the research of about 2000 top scientists. The verdict of a body such as the IPCC must be heeded! The signs of global warming are everywhere. The planet’s glaciers and ice sheets are shrinking. Eleven of the twelve warmest years recorded since 1850 have occurred in the past 12 years. World temperatures are rising progressively and are now 0.76º C warmer than in the ‘preindustrial period’ before 1850. This temperature rise might not at first glance seem significant. But scientists agree that a further rise of 2º C would probably unleash an unstoppable climate change that would have horrific effects for our planet and its inhabitants. The effects of severe global warming would affect people everywhere. • If the great ice caps of Antarctica and Greenland melt, sea level will inevitably rise – perhaps by as much as several metres. Such a rise would inevitably result in the widespread flooding of highly The melting of glaciers on populated lowland areas throughout the world. Mount Kenya is likely to • Climate change will bring strange and extreme weather patterns seriously reduce water and to many parts of the world. Ireland might be warm enough to hyd ro-electricity supplies to the grow grapes and to harbour malaria. On the other hand, if rising city of Nairobi. water temperatures in the Arctic cause the North Atlantic Drift to stall, our harbours could suddenly freeze in winter. • Some parts of the world may experience prolonged and destructive rains. But many more regions (an estimated 50% of How can there be glaciers on the globe by the year 2090) would experience devastating Mount Kenya, which is situated droughts and water shortages. As a result, African crop yields almost on the Equator? could be reduced to 50% of their already inadequate levels. Mass famine would almost certainly follow. As with most global disasters, it will be the poor who suffer most. Fact: Puzzle: The principal motor of global warming is the ever-increasing use of oil and other fossil fuels that release more and more Carbon Dioxide into the atmosphere. Rapid population growth in some Third World countries plays its part in this. But the main culprit is far closer to home and resides in the ‘throw-away’ consumer society that now holds sway throughout much of our ‘developed’ world. It is the rich minority and not the poor majority within our planet that are the main culprits of global warming. The United States, for example, houses a mere 5% of our human family but emits more than 20% of all global CO2 emissions. Nor can Ireland be proud of itself. Our near addictive use of motor vehicles has resulted in a staggering increase of 140% in transport-related greenhouse gas emissions between 1990 and 2004. The rapidly growing economies of China and India also pose potential problems. These countries house a total of more than two billion people or one-third of the world’s population. What would happen to world climates if large proportions of Chinese and Indians were to copy the ways of the West and seek to make petrol-guzzling cars, foreign holidays and endless electric gadgets part of their everyday lives? It is still well within our power to save ourselves from the ravages of global warming. What we need now is an outbreak of sanity among world leaders and among ourselves. Now that world leaders have met at Bali, Indonesia, to discuss climate change, it is essential that they agree on and carry out a meaningful programme of action to reduce greenhouse emissions. We, as individuals, have our own vital roles to play. If global warming is to be contained, many of us in the Western World will need to make serious and perhaps painful alterations to our lifestyles.
