Soil health and land management

What this life looks like

You understand the living foundation of all food production. Soil Scientists study the physical, chemical, and biological properties of soil — the medium in which nearly all the world's food grows. Africa's soils are enormously diverse and face growing threats from erosion, degradation, over-fertilisation, and climate change. Soil scientists who can restore and improve African soils are protecting the continent's agricultural future.

What she actually does

You collect and analyse soil samples to assess fertility, structure, pH, and contamination, map soil types across landscapes, develop soil management recommendations for farmers and land managers, conduct research on soil health and carbon storage, advise on fertiliser application to avoid nutrient depletion and environmental damage, support environmental impact assessments, and develop soil restoration programmes for degraded land.

Why it matters in Africa

Over 40% of African agricultural soils are significantly degraded — depleted of nutrients, compacted, or eroded. This degradation reduces yields and drives farming communities into deeper poverty. At the same time, Africa's soils represent one of the planet's largest potential carbon sinks, making soil science central to climate change mitigation strategies. Soil scientists who can develop restoration programmes at scale are doing vital work.

Your pathway in

  • Study Soil Science, Earth Sciences, Environmental Science, or Agriculture with a soil focus
  • Develop strong laboratory skills: soil chemistry, biological analysis, and remote sensing complement field skills
  • Consider the African Soil Information Service (AfSIS) research community — they are building the most comprehensive soil database in Africa
  • Gain field experience in diverse African soil environments — the variation between forest soils, savanna soils, and semi-arid soils is enormous
  • Develop GIS skills — spatial mapping of soil properties is increasingly central to soil science research and advisory work

Skills you will need

  • Soil sampling and laboratory analysis
  • Soil chemistry and biology
  • GIS and spatial mapping
  • Fertiliser recommendation development
  • Report writing
  • Field survey methods

A woman in this field

Generose Nziguheba

Rwanda

Generose is a Rwandan soil scientist and researcher at the International Fertilizer Development Center (IFDC) and affiliated with the University of Leuven, Belgium. She has spent her career studying soil fertility across Sub-Saharan Africa and developing evidence-based recommendations for fertiliser use that increase crop yields while preserving soil health for future generations. Her research has been influential in shaping national soil fertility programmes in Rwanda, Kenya, and across East Africa. She is one of the most published African women in soil science.

Take your first step

  • Collect soil from three different locations near you — a garden, a roadside, and a forested area — and compare their colour, texture, and smell. These physical properties tell you a great deal about soil health
  • Research the African Soil Information Service at africasoils.net — they have mapped soils across the continent and their data and publications are freely accessible
  • Study what the Soil Carbon Index is and why soil carbon matters for both agriculture and climate change — it is one of the most important concepts in contemporary soil science
  • Look into the Soil Science Society of South Africa or equivalent national soil science societies — they offer student membership and learning resources
