farming

• Lava and ash erupting from volcanoes kill livestock and destroy crops and vegetation.
• After thousands of years, weathering of this lava releases minerals and leaves behind extremely fertile soil, rich in nutrients
• Land can be farmed productively in these areas to provide a source of food and income.
• Volcanic soils are found on less than one per cent of the Earth's | surface, but support 10 per cent of the world’s population.
