Problems and Solutions of Agriculture in Rwanda
Lesson 1 of 4
20 min
Let's begin
Stand on almost any hill in Rwanda and count the fields you can see: dozens of small plots of beans, bananas, maize and cassava, running from the valley floor to the hilltop, with houses scattered among them. More than two-thirds of Rwandan households farm, and farming feeds most families. Yet all of these farms must share a small, steep country with a fast-growing population.
This unit looks at the problems that hold Rwandan agriculture back and at the solutions being used to overcome them. In this first lesson you will study the problems that come from the land itself: land pressure, land fragmentation, and soil erosion and landslides on the hillsides.
Rwanda has a total area of only 26,338 km², and its population was estimated at about 14.6 million in 2025. This makes it one of the most densely populated countries in Africa.
Worked example
how much farmland is there for each person?
So a family of six has, on average, about 0.66 ha from which to grow all its food and something to sell. (Figures rounded; estimates from Wikipedia, read in September 2026.)
Land pressure sets off a chain of further problems:
Traditionally, family land is divided among the children when they marry or when the parents die. Each generation receives smaller pieces, and one household may end up farming four or five tiny plots on different hills.
Worked example
fragmentation by inheritance (illustrative figures)
Why fragmentation lowers output:
Most Rwandan farms lie on slopes. Rain totals of about 1,000 to 1,400 mm a year fall in two rainy seasons, often as short, heavy storms. A 2025 policy brief by AGRA and IFPRI estimates that about 40% of Rwanda's land is affected by soil erosion.
| Type | What happens | What you see on the farm |
|---|---|---|
| Splash erosion | Raindrops strike bare soil and knock particles loose. | Mud splashed on plant leaves and house walls. |
| Sheet erosion | A thin, even layer of topsoil is washed off a whole slope. | Paler soil, exposed roots and stones. It is hard to notice until yields fall. |
| Rill erosion | Runoff gathers into many small channels. | Small channels a few centimetres deep running straight downhill. |
| Gully erosion | Rills join and cut deeper and wider. | Deep ditches that split a field and cannot be dug over. |
| Landslide | Days of heavy rain soak a steep slope until a whole mass of soil slips. | Bare scars on hillsides; buried fields, houses and roads. |
Causes on Rwandan farms: cultivating steep slopes, especially when rows run up and down the slope; bare, freshly dug soil when the heavy rains arrive at planting time; clearing of trees and grass; overgrazing; and paths and roads that channel runoff onto fields.
Effects:
Tip
Exam technique: write each problem as a chain of cause → problem → effect on farming. "Land is divided among children at inheritance (cause), so farms become small and scattered (fragmentation), so farmers cannot use machines and waste time walking between plots (effect)." A chain earns more marks than a single word.
Memory hook: the three land problems are "crowded, cut up, carried away": land pressure, fragmentation and erosion.
Distinguish between land pressure and land fragmentation.
Solution: Land pressure is the strain on land when many people depend on a limited area. Land fragmentation is the splitting of each farm into many small, scattered plots. Land pressure is one cause of fragmentation: as the population grows, the same land is shared among more heirs.
A district has 360,000 people living on 600 km². Calculate its population density.
Solution: Density = 360,000 ÷ 600 = 600 people per km².
A 1.6 ha farm is divided equally among 4 children. Each child's share is later divided equally between 2 grandchildren. What area does each grandchild receive, in square metres?
Solution: 1.6 ÷ 4 = 0.4 ha; 0.4 ÷ 2 = 0.2 ha. 0.2 × 10,000 = 2,000 m².
Give three reasons why land fragmentation lowers a farm's output.
Solution: Any three of: time is wasted walking between plots; plots are too small for machines or ox-ploughs; boundaries and paths waste land; distant plots are hard to supervise and protect; inputs and pest control are hard to organise across many small plots growing different crops.
Explain why soil erosion on a Rwandan hillside farm is usually worst at the start of a rainy season.
Solution: At planting time the soil has just been dug and is loose and bare, and the young crops are too small to cover it. The first heavy storms therefore strike unprotected soil and wash it away. Later in the season the crop leaves and roots shield and hold the soil.
