Nature
Nature challenges humans in many ways, through disease, weather and famine. For living along the coast, one unusual phenomenon capable of catastrophic destruction is the tsunami. A tsunami is a series of waves generated in a body of water by an impulsive disturbance. Earthquakes, landslides, vocalnic eruptions and even the impact of meteorites can generate tsunami.Starting at sea, a tsunami slowly approaches land, growing in height and losing energy through bottom friction and turblance. Still, just like any other water waves, tsunami unleash tremendous energy as they plunge onto the shore. They have great erosion potential, stripping beaches of sand and flooding hundreds of meters inland.
Nature
In countries like Niger and Mauritania, the cultivation of land has changed little in the past several countries. Additionally, these countries' mono-modal rainfall pattern brings precipitation for only three months the year. As a result, food production doesn't nearly meet demand. Several agencies and organizations have intensified their efforts to increase the productivity of the land in these countries. They have introduced new strains of seed, improved irrigation techniques, and introduced new methods of fertilization and soil management. With ample sunlight for photosynthesis and modern irrigation techniques, sustainable farming techniques should allow farmers too boost aggregate production in order to meet demand.

The biggest hurdles are political corruption, incompetence and the absence of a marketing infrastructure.
