From 5 to 18 Sep, I with FOLENS members spent the time in Ghana to
investigate the environmental issues. We cooperated with two
universities and went to two cities in Ghana-capital Accra and Kumasi.
During the days in Ghana, a lot of problems on environmental
were
shown up, especially the part of soil erosion. The 7 soil samples were
taken in 6 places, and then analyzed for physical and
chemical
properties, such as soil color, soil texture, soil pH value,soil EC
value. The color of the most soil surface in Ghana was reddish
brown,
sand texture. The soil pH value in mining places were around 5.0,
little bit acid than the samples around the universities. After the
analysis, we showed our data to the Ghanaian students, had a
discussion with enthusiasm. We tried to find a better way to prevent
and
solute the issues in Ghana, we also brought the advices of
Japanese and Chinese advanced experiences to them. All the Ghanaian
and
us want to build a sustainable development environment, a
beautiful future.
Key words: Ghana, soil erosion, pH, EC
