Exploring secondary projects


With elections, celebrations, and Peace Corps meetings I didn’t do much work on my primary project this week. Next week is the last week of term. Tuesday will be kite flying and Thursday will be the last day of the term. I might have some time with the students as the teachers are working on the final reports – fingers crossed.

In addition to their primary project volunteers often work on secondary projects. These typically marry the interests and abilities of the volunteer with the needs and desires of the community.

My approach to secondary projects is get to know the people and the place first – paying attention to what is needed and community interests. In Ghana I worked on a computer lab and library for the school as well as some agriculture projects to improve family nutrition.

The government is building a new school for my community that should be ready next school year. Therefore, I’m not focused on much related to the current facilities.

As a lifetime gardener – I’m drawn to agriculture and soil conservation, improvement. I’m also interested in sustainable economic and ecological practices.

Corn is doing well, beans replanted, and sweet potato trying to take over. 

My garden right now would not be considered a secondary project. It is, in part, an exercise to better understand agriculture on the island. In a community of farmers there is little that I could add to their knowledge. Perhaps composting, vermiculture, and no-till systems – but that would required more research in current practices and issues.

The problem of erosion


Most Caribbean Islands were formed by volcanic activities. The tall body of Dominica will eventually be worn down by erosion to look more like Grenada. That is nature. The Grand Canyon is just gully erosion that has gone on for a very long time.

Man can increase the rate of erosion. Farming – removing native vegetation, tilling the soil, and other activities can increase the amount of soil erosion. Infrastructure such as roads and buildings can also increase erosion. Basically, rather than water having the means and time to soak into the ground and renew aquifers, it rushes along the surface or subsurface and carries soil downstream to the ocean.

The land available to Caribbean islands for agriculture is already limited. Slopes, more prone to erosion, must be used on the islands to support the needs of the population for food and export.

However, the loss of fertile soil for growing plants is just one problem. Another is that the soil goes somewhere else. The coastal waters are important for food production and for the beauty of reefs to be enjoyed by citizens and tourists. Eroded soil as well as the littering and plastic waste that are carried to the ocean harms the coastal waters and reefs surrounding the islands - impacting fishing and tourism.  Degraded reefs also reduce the ability of natural systems to protect the island from weather events.  (Expect a littering tirade sometime in the future.)

I don’t have to go far from my front door to see some signs of erosion nor one of the proven methods to significantly reduce soil erosion.

Slip erosion across the street. I think the drainage pipe was recently extended.

The land next door is creeping past the concrete and chain link fence line.

Vetiver row - it's width indicates it has likely been here a long time.

Little sign of erosion.  It is common practice to weed to bare ground along roadsides.

So, literally every day I walk out of my front door I am face to face with erosion on the island of Grenada and one solution to the problem. Although I already knew about vetiver and erosion, I’ve spent the last couple of months researching the topics.

Vetiver grass has very strong deep thick roots that don’t spread out. Most varieties don’t produce seeds or otherwise spread excessively to become a weed. It is relatively easy to cultivate and can thrive in a variety of locations and conditions. It is easy to establish along contour lines to protect slopes and promote terracing.  It can be used to protect stream banks and other areas.  Vetiver requires little maintenance. Some plantings on Pacific islands have remained functional for nearly 100 years.


I’m not nearly at a point to consider this a potential secondary project. However, I believe that controlling soil erosion would be useful to Caribbean islands by improving:
  • agricultural productivity
  • watersheds and 
  • the coastal ecology on the islands. 
I think it is a small but critically important component for the sustainable and climate resilient future of the islands. Hopefully, more to come. In the mean time – I need to get back to my literacy project.


Love always,
John

Yam harvesting

Image
Roger and I went to farm to harvest yam on Saturday morning, September 13, 2014.  In Ghana a yam is a root crop that is different from a sweet potato.  We have sweet potatoes here as well. Yam recently harvested Preparing a yam for boiling The yam has a white flesh – softer than a white potato. In this area the yams are planted between April and June.  Harvest continues into December and January depending on the weather and pigs getting into the field. The plant is a vine – which is grown on stakes rather than allowed the spread out.  The plants are placed on a raised bed about 2 feet high.  The beds are surrounded by flat trenches.  This allows the rains to flow around, but not wipe out the yam crop.  Intercropping seems to be common practice with yams planted in the raised bed, soybeans around the edges, and rice in the trenches.  The occasional corn or okra plant is also among the yams – although the bulk of those crop...

Pito – brewed millet

Image
Corn, rice, and millet are the common grains grown in my region of Ghana. All three are used food, but millet is also used to produce the local brew – pito, or daa in the local language. “N nyu daa” - in Dagaree means “I drink pito.” There are several varieties of millet grown here – a red and white varieties have loose heads. These are used for pito and other foods. There is also a smaller seed variety with a tight head of seeds that is mainly used for porridge. (Don't have a picture of that variety yet.) In all varieties millet grows on a stalk with the grain head at the top of the stalk. White and red millet in the field Two bundles of while millet to be used for seed next season Converting a grain to alcohol is a common practice in various cultures. It provides a way to capture and digest the nutritional value of the grain. In some places, like Germany and the beer brewing monks, the making a beer was a way to preserve the harvest. In Ghana the millet is ...

Ghana Archery and Travel to Tamale

Image
Ghana Archery Roger and I were walking to see a man in the community early last week and he happened across an arrow head. It was a long thin metal piece that would be attached to then end of a shaft. That got Roger talking about archery and got me thinking about another blog post. He explained how the arrow worked while we walked and promised to show me a bow and arrow when we got back to his house. He talked about the old times when they made poison. The process involved collecting plants and such things and placing them in a pot which is buried for a year. The poison was used on animals and people in the ancient times. That got me thinking about the information that has been and is being lost in the community from the older generation. Yesterday, I was sitting talking with some of the older men and they were talking about how the grandfathers could dig up the roots and such to make medicine for a variety of illnesses. They told me that the knowledge and practice of m...
