What did
I do specifically?
Well, my village was pretty far south, about 5km from Nigeria, in a lowland area and surrounded by ridges of mesas (that cluster of green trees in the middle = my village.)

We didn't have a problem with sand dunes, desertification, or hardpan. Mostly my villagers were interested in planting trees in their yards and starting mango orchards.
Part 1. The Women's Group, Mundangwara
("we are patient")I spent a lot of time working with the women's group established by the last volunteer. These women held weekly meetings where everyone paid a contribution to a cash box. About twice a year, each woman was given a loan from the cash box, and paid a monthly interest fee until the balance was paid off. At the end of the year the interest money was split among all the women for a little bonus to use for the holidays.
Some ladies from the women's group with their cash box.

The women's group was provided with a beautiful fenced-in garden space (the former volunteer obtained grants for materials and labor) complete with a well. They were supposed to maintain a vegetable garden during cold season (December through April), but they weren't exactly motivated. They planted peanuts during rainy season (June through September), but this year they didn't get themselves organized enough to actually harvest the peanuts and somebody beat them to it and took them all.
However, they have a space they are free to use for individual projects or as a group, and if they someday want to create a big garden, at least they have a place to do it. In the meantime, a couple of ladies grow hot peppers and moringa trees.
At the advice of my boss, I helped the women obtain loans from a microfinance bank in Konni (18 km from my village) to each purchase an animal for profit. They bought rams, sheep and goats.

I brought in a herder and a large-animal veterinarian to educate the women on how to keep their animal healthy and fatten it up as much as possible to make the most profit. Six months later they sold the animals and paid the loans back with interest.
There were a couple of problems with this project. First of all, the microfinance bank we worked with was
slow. They made the women pay money to join the loan program, then didn't actually give them a loan for six months. The guy we worked with continuously tried to sexually harass me and it put me in a weird position. A couple of the women's animals died, but it was for preventable reasons. Lastly, one woman didn't even want a loan, so she gave her money to a friend. The friend gave it to a guy who needed money to travel to Nigeria. By the time loans had to be paid back, the guy hadn't yet come back from Nigeria. The women's group cannot obtain future loans if even one person defaults, so they got his elderly parents to repay the loan.
Part 2. Well improvement projectThis NGO (non-governmental organization) came to my village and built a new well. It was great because the well was situated near where all the herders live, and they have hundreds of thirsty cattle to water every day during the dry season.

They were using these small, shallow metal bowls to give each cow water.

None of the wells in my village had drinking troughs and the new well didn't have a decent apron (ledge to prevent sand from blowing inside). I used some project money left by the last volunteer to build a new apron and some water troughs for the animals.


The finished product:

We later realized the new well wasn't deep enough. The water came up muddy at best and sometimes there wasn't any water at all. Since the water was so dirty none of the nearby houses used it and the women had to walk all the way around the village to a different well when there was one right behind their property!
I organized a group of herders to improve the well, as they were its main users. I hired a couple of professionals to go down inside the well and put mud into buckets to deepen the floor of the well.
If you look closely you can see them in the bottom:

My friend Darey and I made the workers strong green tea for strength and even sent some down the well in a bucket:

After this project the well was deeper and had clear, plentiful water. Yay!
