What is agricultural flooding?

What is agricultural flooding?

Flooding affects several aspects of agricultural production and productivity. There are losses in crops washed down by inundation. In many instances, the crops are unrecoverable after a flood occurs. When flooding occurs, water carries silt & sediments down the lowlands which could be valleys, rivers or dams.

How does flood affect vegetation?

There are many ways that flooding can damage plants. Excessive moisture in soil decreases oxygen levels. This impedes respiration (where energy is released from sugars) in the roots leading to the build-up of carbon dioxide, methane and nitrogen gases. Ultimately, the roots can suffocate and die.

How do crops grow during floods?

Plant in raised beds or use berms to divert excess water away from trees and shrubs. If possible, avoid planting in areas that drain slowly or remain flooded after a heavy rainfall. If your soil is subject to standing water, it is best to plant species that are tolerant to wet soils.

How does water pollution affect agriculture?

Effects. Agricultural water can become contaminated through a variety of ways and can potentially spread bacteria, viruses, and parasites to crops and animals.

What is agriculture affected by?

Changes in ozone, greenhouse gases and climate change affect agricultural producers greatly because agriculture and fisheries depend on specific climate conditions. Temperature changes can cause habitat ranges and crop planting dates to shift and droughts and floods due to climate change may hinder farming practices.

How do floods impact plants and animals?

Many plants and animals rely on flooding for their species to prosper. As fish and some other aquatic animals breathe the oxygen from the water, critically low oxygen levels can cause some fish to die.

How do floods help plants?

Flooding Influences Plant-Available Nutrients For example: Soil lost due to erosion can take with it valuable plant-available nutrients and organic matter. Deposition of sediments from floods may increase the level of nitrogen, phosphorus, silicon, and potassium in the soil.

What are the effects of water pollution on plants and animals?

The effect is that it breeds algae growth and causes the growth of much more water organism. This algae attack affects fish and other aquatic animals by absorbing and reducing their oxygen supply. Algae growth also clogs fish gills.

What are the effects of floods on agriculture?

The impact of floods on agriculture can take decades to recover. They include damage of crops, livestock and property. The effects of floods on animal’s health, growth and productivity is massive. They cause feed shortage, dehydration and increase the risk of infections.

What are the effects of floods in Nigeria?

Flood over the years has caused severe damage to property, infrastructure, crops and deaths across the country, and has been considered as a source of increased risks to disease and hunger (Baiye 1988; Edward-Adebiyi 1997), damage to property, loss of life, contamination, and spoiling of agricultural land (Umoh, 2008).

What happens to animals when there is a flood?

This poisoning can cause animal death or long-term chronic illness. Dehydration: Floods can lead to dry water taps animal dehydration. They contaminate water sources with dirty water and block pipes. Animals will have an inadequate supply of drinking water and may end up suffering from dehydration.

What is the economic impact of Agriculture in America?

U.S. agricultural exports alone generate more than $100 billion annually in business activity in the U.S., and provide jobs for nearly one million workers. Agriculture is also the biggest consumer of U.S. water resources, accounting for over 80% of the nation’s consumptive water use.
