1. export There are many ways to export products. http://www.starfireusa.com/CMSUploads/ExportServices2.JPG
To export a product, a country needs a way to send it out of the country. http://www.chinasignpost.com/wp-content/uploads/2011/01/sudan-map-21.jpg
1. export: send something out of the country to sell http://www.auguricom.com/Import--and--Export.php
3. developing country But most African countries are still developingcountries. The U.S. is already a developed country. http://www.fullpassport.com/Trip2001/Images11/timsuburb.jpg
Developing countries may be poor, or they may be a mix of modern and poor. Pakistan Brazil http://www.dictatorshipwatch.com/wp-content/uploads/2008/12/poverty_children.jpg http://media.photobucket.com/image/sao%20paulo%20poverty%20wealth/wishbone98/Sao_Paulo.jpg
3. developing country:has very limited industry & technology and often poor

Other examples of developed countries are Japan and France. Paris, France http://d2f29brjr0xbt3.cloudfront.net/270_skyline/newyorkskyline.jpg
4.developedcountries:have lots of technology and are usually wealthy
5. landlocked There are only 2 landlocked countries in South America, but there are many in Europe. http://d-maps.com/m/europemin/europemin09.gif http://www.harpercollege.edu/~mhealy/g101t/studygd/unit2/samer/smclosed.gif
5. landlocked: a country that does not border the sea Landlocked countries better get along with their neighbors if they want to export things by sea! http://www.mapsofworld.com/africa/thematic/maps/africa-landlocked-countries.jpg
6. subsistence farming Subsistence farms are small. There are many subsistence farmers in developing countries. They don’t usually have extra to sell for profit.
6. Subsistence farming produces just enough food to help feed the farmer’s own family.
7. drought Deforestation can make droughts more severe.
7. drought: a time with very little rainfall. http://www.flickr.com/photos/photographerglen/963960046/
8. erosion http://www.wordiq.com/definition/Erosion Deforestation leaves the soil with no trees and tree roots to protect it. This leads to serious erosion.
Deforestation anderosion leave the soil less able to absorb rainwater. So flooding is more common during heavy rain.
Erosion by the Colorado River formed the Grand Canyon. 8. erosion:the process of soil or rock being washed away http://www.flickr.com/photos/67307569@N00/2616398736/
9. Sahel http://www.syngentafoundation.org/images/sahel_zone.gif
It looks like this. . . http://www.eduspace.esa.int/Background/images/Sahel1.jpe http://www.eduspace.esa.int/Background/images/Sahel2.jpg
9. Sahel: the dry grassland on the south edge of the Sahara Desert Sahara Desert Sahel http://newsimg.bbc.co.uk/media/images/41074000/gif/_41074256_africa_sahel_map203.gif
The Sahel has a shortage of arable land. 10. arable http://farm8.staticflickr.com/7251/7838744884_5a9323efa9_z.jpg
10. arable: land good for farming http://www.fernleighfarms.com/images/rows_green.jpg
11. overgrazeWhen animals graze too long in one area, they strip the leaves off trees and tear plants up by the roots. This permanently kills plants and trees. http://www.eduspace.esa.int/Background/images/Sahel1.jpe
11. overgraze: letting herds eat too much in one area, permanently damaging plants http://geographyfieldwork.com/soiler12_small.jpg
12. slash-and-burn This is a traditional way of clearing land for subsistence farmers – worldwide. http://www.listentoafrica.com/wp-content/uploads/2009/11/web430-GW-G9-15NOV09-036.jpg
In an area with low population density, this works well. http://www.dkimages.com/discover/previews/786/586368.JPG They farm the land, let it grow back for many years, and eventually re-cut it.
But in modern times, high population density means they can’t wait to let the trees grow back. http://www.dkimages.com/discover/previews/786/586368.JPG
They just keep using the land – over and over – until it is no longer fertile, then abandon it to erosion. http://www.dkimages.com/discover/previews/786/586368.JPG
Slash-and-burn farming often leads to serious soil erosion http://photos.mongabay.com/06/1125marojejy.jpg
and deforestation. http://www.wtamu.edu/~crobinson/Erosion/erosion7.jpg
12. slash-and-burn: cutting down trees and bushes & burning it to get ready to farm http://www.plexuseco.com/EPOW/EPOW-Archive/archive_2006/EPOW-060515_files/5648%20Congo%20Basin%20shift%20cultivn.jpg
13. desertificationOvergrazing, slash-and-burn farming, and drought can all cause desertification. http://www.dkimages.com/discover/previews/769/551267.JPG
Desertification Deforestation Healthy Land http://www.dkimages.com/discover/previews/769/588782.JPG
13. desertification: the process of land becoming desert http://www.uwsp.edu/geo/faculty/ritter/geog101/textbook/images/lithosphere/eolian/desertification_africa_fao_11638.jpg
14. reforestation http://www.cru.uea.ac.uk/~carolm/vietnampics/Reforestation_centralhighlands2.JPG
In Benin, these farmers plant trees to use just for firewood and fencing. That saves the natural growth trees. http://www.opecfund.org/about/images/sustainable_development_4_0001.jpg
14. reforestation: replanting trees that have been destroyed by deforestation http://www.africanimpact.com/blog/wp-content/uploads/2012/03/Token-picture-lr.jpg
What has happened between the 1975 satellite image and the one from 2005? http://conservationmagazine.org/wordpress/wp-content/uploads/2012/02/Sahel-Satellite-sm.jpg
15. crop rotation GRAINS http://moofafrica.com/wp-content/uploads/2013/02/crop-rotation.png
Planting the same crop in the same field every year takes the same nutrients out of the soil every year. http://farm3.staticflickr.com/2636/3703600484_bcea1c578a_z.jpg http://ts4.mm.bing.net/th?id=H.5054194074518695&pid=15.1
