A Waterfall Day

(Sunday October 30th)

The morning after we returned from Kokrobite, we decided to rent a car and a driver and go to Shai Hills Forest Reserve. While I would STRONGLY discourage anyone going here, I would encourage people to instead make the trip to Akaa and Boti waterfalls in the Volta Region. 
Me at Akaa Falls

I love the Volta Region, and really, I don’t need to be asked twice to go there for any reason. The roads are surprisingly pretty good and the driver can make all the difference between a reasonably comfortable journey and a back-breaking, bone shattering trip. Luckily, we had a great driver. 


Steps leading to Akaa Falls
The weather was perfect for taking pictures




Umbrella Rock


Me under the Umbrella Rock



Our first stop was Akaa falls. I couldn’t tell you where it is but I’d say it’s about three hours drive at least from Accra. Unlike our previous trip to Volta which involved scaling Mount Afadjato, reaching the falls was relatively simple. We paid the guide who walked us down the path. I really wish he had told us about the place, he didn’t speak to us once really. I took tons of pictures (as usual), and it was very pretty. There was a lot of water because of all the rain we have had lately. We took more pictures then went to see the Umbrella Rock. The rock was really cool and we were able to climb up under the umbrella part. You used to be able to climb on top of the umbrella but because it is quite dangerous, they don’t let you do that anymore. There was a village on the hillside across the valley and I would totally love to live there!

Boti Falls

Steps to Boti Falls. There was quite a lot of them!

Our next stop was to Boti Falls, a short distance away from Akaa Falls. This time we didn’t have a guide but we had to pay a second fee to get in. There was some dispute about the actual cost of entering but eventually we were on our way down the steps to see the falls. There are two sides of Boti Falls, the female side and the male side. The falls are beautiful despite not being as tall as the Wli Falls. For once we didn’t have rain to ruin our trip. While it wasn’t the trip we had planned on taking, it was still a worthwhile trip.

Tema-Accra Flooding


This was one of my school submissions but I thought it was a really interesting topic so I reposted it here

The rains should have stopped in Accra in September, however we are still experiencing heavy rains at the end of October. The flooding that resulted from the heavy rain from Monday to Thursday of this week has claimed the lives of 9 people in the Tema-Accra area in addition to the destruction of homes and many businesses. 
During a trip to the Volta Region this weekend, we endured incredibly violent rains as we climbed to the top of Mount Afadjato. The rain made descending the mountain very dangerous and we could tell that the village was going to experience some flooding as the sewers couldn’t cope with the water. The remainder of the trip was sadly called off due to the weather. The long drive back to Accra was slowed because the water had flooded or washed away the road in many places. Some of the small villages we passed were flooded after only a few hours of rain. It was obvious they would have major clean-ups to do once the rain had stopped.
Accra and the surrounding areas have been pummeled with heavy rain and thunderstorms this week. One severe storm on Monday was literally on top of my building, I’ve never been woken up by such a loud storm in my life. Despite being located on top of a hill, campus has been flooded with water and the sewers, clogged with empty sachets and black plastic bags, couldn’t drain the water resulting in a wonderful smell coming from overflowing gutters. If the existing sewers were clear of debris, the flooding would not have been so severe. According to the Daily Graphic newspaper, this is a reminder that efforts to improve infrastructure and planning in Accra are greatly needed in addition to educating the public of the need for insurance to help people recover from such a disaster.
There are three issues at play here. First, the changing of the seasons. People at work have repeatedly commented that we shouldn’t be experiencing rain at all in October and that this is a prime example of the effects of climate change (I couldn’t agree more). People here seem to be able to identify changes in the rainy season as being a direct, observable result of climate change. The link between the unbelievable car emissions and climate change doesn’t seem to resonate as much. I still find it puzzling how nobody finds it as appalling as I do! I like that people are able to identify what they are experiencing as a result of climate change however they don’t propose any actions to limit it. Secondly, there is a huge lack of infrastructure in Accra. The open gutters and sewers are incapable of coping with such a large amount of water. Smell aside, overflowing gutters present a huge health problem for people including a higher risk of malaria (from standing water where mosquitos breed), to the unsanitary conditions of having waste and garbage floating around. The biggest issue is flooding, as experienced this week. The newspaper indicated that many businesses had to close in areas where the flooding was severe. The National Disaster Management Organisation (NADMO) did respond and helped people pump water from their homes however many in areas like Santa Maria spent the night on their roofs in the rain to avoid the flooding. Thirdly, the victims of the flooding are hard-pressed to find a doctor as the doctors strike has yet to be concluded here. Doctors have now been told to stop providing emergency care to force the government to meet their demands.
After seeing the pictorial and news articles in the Daily Graphic, I am reminded that although the rain inconvenienced me this week, it could have been much much worse. Hundreds of people lost their businesses, personal property, even vehicles that were swept up in the flooding. My office remained open during the flooding as Legon is not a low-lying area and other than getting quite wet on my trip to and from work, things were normal. I know people in the office were very upset by this newspaper yesterday when it was published, now I know why. Some suggestions proposed by government officials in the newspaper are to change people’s behaviour when it comes to waste disposal. All of the discarded plastic waste clogs up sewers and hinders an already overextended system from operating optimally. The other aspect, which relates to city planning which seems to be completely lacking in most parts of the city, is to prevent people from building on water courses.

Gasland & Hydraulic Fracturing or Fracking

As countries around the world begin to explore alternative energy sources than petroleum, natural gas is of growing interest. I must admit I knew virtually nothing about how natural gas comes to be in tanks and canisters. I knew that companies are conducting exploration drilling in the Canadian Arctic to explore natural gas reserves. While mineral and energy extraction in the Arctic is an important issue unto itself, the main focus of my current interest is natural gas extraction in the United States and the implications of this for the rest of the world. This brings me to the documentary by Josh Fox called Gasland. This Oscar nominated documentary discusses the hazards of fracking in the United States and the politics behind this booming industry. The main focus of this film was water and the impact the fracking process and natural gas extraction has on the water supply. If you have read Bottlemania, or if you are interested in issues surrounding safe drinking water, you would probably enjoy this film.
Trailer to Gasland

What is fracking?
Fracking is a method used in deep well natural gas extraction. A combination of over 596 chemicals (80-300 tonnes each time), sand, and 1-8 millions of gallons of water is pumped into a well to break up the shale and ease the extraction of the natural gas. The water used becomes contaminated and of the water that is pumped out of the well, all of it is contaminated and must be cleaned and disposed of. During the lifetime of a natural gas well, it can be fracked multiple times (up to or beyond 10 times). These gas wells are drilled to 8000ft and most water aquifers are around 1000ft below the ground. The big concern is when the well casings leak or when water supplies are contaminated. This brief explanation is very over-simplified and there are great resources available on YouTube if you want to learn more about it.

What frightened me about this whole process beyond the safety issues of the wells and the potential for explosions was how the companies doing the drilling are not required by law to declare what chemicals they use for this process. Natural gas drilling companies are exempt from the Safe Drinking Water Act (1974), which is in place to ensure that drinking water is kept clean from contamination. This exemption is commonly referred to as the Halliburton Loophole which was part of the Energy Bill passed in 2005 by the Bush administration. The Safe Drinking Water Act is in place to ensure that water resources are protected and not destroyed by industry or natural processes. While in some cases, citizens have been able to sue the gas companies and have them provide alternate water supplies (the gas companies will build a large tank and fill it up with water trucked in from elsewhere), however countless other families are left to fend for themselves.

Global Implications
How does this problem in the United States relate to international development? While current attention is focused on the fallout from fracking in the United States, other countries (including Europe and Northern Africa) are exploring fracking as a means to access natural gas reserves. If the United States is the model on which other natural gas drilling enterprises are mimicking, there is the potential for some serious problems. Clearly, there are health and safety issues surrounding natural gas extraction that have yet to be addressed and those with a vested interest in the operation of these drill sites are unwilling to take a critical look at the operation of these facilities. Hopefully before this technology is used in other parts of the world there will at least be independent study of some of these issues. Am I opposed to natural gas extraction? No. If natural gas companies were held to environmental standards and were able to prevent much of the water contamination that is currently happening, I don't see a problem in making use of this natural resource. However, while citizens of the United States can continue to set their water on fire, natural gas drilling is cause for concern.
