There are three types of flooding. The first type is pluvial. Pluvial is excessive or extreme precipitation, that covers the land. The second type is called fluvial. Fluvial is excessive river or stream flow where a river or stream spills outside its banks onto its adjacent lands. The third type is costal flooding. This is caused by the lunar cycle where extremely high tides inundate the land next to the cost.
<span>The two primary causes are climate change, resulting in increased severity and intensity of rainfall, and new developments on floodplains, which are themselves at risk of flooding, and which increase the risk of flooding downstream. [ The effects of flooding from the sources outlined above are felt by various 'receptors'. These include, people, buildings, infrastructure, agriculture, open recreational space and the natural world. In extreme cases flooding may cause a loss of life.</span>
As the resources in the world are distributed unequally, the crops and the ability to grow them in specific environmental conditions such as near the river valleys, on the foothills of the mountains and near the flood plains differ worldwide as many places don't have enough sunlight,
many places is too warm or hot for there growth and other place are too cold or are locates at great heights. Variation thus exists in the cropping patterns and the cropping intensity as they need specific conditions as climate, weather, and soil properties.
Many of the earlier civilizations developed and prospered near the river valleys.
