Growing food-crops on the shores of Zambia's Lake Kariba, the biggest man-made lake of Africa, is quite a challenge. Despite the nearby water the farmers are facing drought on their land.
The locally made 'treadle pump', which can be used to pump water by using muscle power, has caused a revolution. Farmers are no longer dependent of the rain season that brings water ones or twice a year. The irrigation is a lot less heavy and the revenues are going up, since there's water in the dry periods as well. Also the quality of the products is improving.
