Uganda is a country in East Africa and,as in many such countries,a high percentage of the population,about 80 percent,are village-dwellers living in huts,which are often no bigger than a garage. The walls of the huts are made of mud,which is held together by reeds and sticks,and the roofs of the older ones are thatched（覆盖）with grass,although an increasing number of newer village houses have roofs made from corrugated（波纹形的）iron.
Several generations of the same family live together in the huts,which are usually divided into two sections by a curtain. The inner section,the one furthest from the open door of the hut,is where everyone sleeps and food is prepared and served in the outer part. If the family owns chickens or goats,they are kept in a small room attached to the main house.
Food is usually prepared on open fires although some people prefer to cook inside. However,this is quite dangerous and also means that the walls of the hut are stained by smoke and the atmosphere is acrid. The family sit in a circle on mats while they eat.
Newer village houses are almost always made of corrugated iron and are bigger,with one or two separate bedrooms and the kitchen in a smaller building beside the main house. But,old or new,the houses are not powered by electricity,and all homes are lit by paraffin（石蜡）candles called “tadobba”.
Nor is there any running water in the houses. Some villages have their own well,but in many cases,collecting water involves a long and arduous walk to a river or spring,carrying plastic containers or pots made of clay.
Children are the ones who have to fetch water,and they have to do this early in the morning before they go to school,or in the evening when they come home. They often have to climb high hills or walk through valleys with narrow paths through dense vegetation. It is no surprise that they grow up muscular and fit after such daily exercise,walking for several kilometres carrying such heavy weights.
