Around 60% of the workforce in Senegal are engaged in food crop production, with small subsistence farms the norm. As women produce 80% of the nation’s food, their empowerment is crucial to rural and agricultural improvement.
Senegal has a tropical climate with dry and humid seasons. Climate change is expected to lead to hotter temperatures and more frequent intense rainfall. This is likely to reduce the yields of key crops such as sorghum and millet. Poor soils and deteriorating forests and water resources pose additional challenges for Senegalese farmers.
The test sites will validate the following technologies:
- Densified total mixed ration blocks for livestock feed
- Pellets for clean household cooking using improved stoves or gasifiers
- Biochar as a solid fuel and soil conditioner and additive in biogas production systems
- Solid fuel for use in clean household cooking using improved stoves or gasifiers
- Biogas as a renewable energy source. Two biogas reactors are already in place at the university
- Digestate for use as a natural fertiliser.
Hydrothermal carbonisation (HTC):
- Test of hydrochar production using high-moisture feedstock
Local feedstock will include:
- Cashew and peanut shells and millet and maize stalks for briquette production, densification and pyrolysis
- Typha and other high moisture feedstock for biochar production by HTC
- Livestock manure, agricultural residues and food waste for biodigestion
