Yes You Can! Prevent Waterlogging And Crop Failure During Floods:
Waterlogging can take place because of heavy rainfall, inadequate drainage systems, natural flooding, etc. So, damage to crops depends on the duration and severity of flooding. The oxygen-deficient conditions hamper plant growth, development, and survival based on their tolerance to excess water.
Why waterlogging needs to be managed?
Waterlogging can lead to, crop and pasture production loss, loss of nutrients, Soil structure decline.
How can we prevent waterlogging?
? An absolute ban on plastic. Plastics create choking points in drainage. It closes down the sinks on the streets.
? There should be a world-class mechanism for garbage disposal. Urban Solid Waste has become real problem everywhere. Collection and scientific disposal should be a priority to deal with Solid Waste.
? The problem becomes severe during high tides when rainwater doesn't flow into the sea. Drainage should not be opened in Sea (like actually done at multiple points like Worli drainage pipes). It should be sent outside the city to sewage treatment plants.
? Nala Cleaning (Sewage) activity should take place year-round, not just during monsoon. It's should be mechanized.
? Principles of Fluid Mechanics can be used to understand the volume of water flowing Mumbai and the capacity of drainage.
? The railway station should be well designed for drainage of water. Flood almost stops local, the lifeline of Mumbai. Using water pumps whenever there is water is so outdated method.
Effects of floods on agriculture Floods can have devastating impacts on farm businesses, affecting livestock, buildings, and homes:
How does flood affect agriculture?
Flooding and wet weather are so costly to agricultural land because they cause delays and reduction of crop harvest. If soil is too wet it can result in poor conditions for the crops to grow; when soil is well drained then the oxygen, nutrients and trace elements that the plant needs are available.
There are some steps you can take to reduce the risk of flooding and minimize the damage caused if a flood does happen:
Farm flood planning
? Identify fields at a higher ground where livestock, machinery, and tools can be moved to safety and gain permission to use these in advance of flooding if they are not your own
? Consider purchasing a stockpile of useful materials that can be used during a flood such as sandbags to prevent water entering barns or sheds, plywood to board up windows and pallets to raise stock and equipment above floodwater level.
Home flood planning
In most cases, the farm will also be a home. In the home, there should be a flood plain and a flood kit, so that everyone knows how to respond if a flood occurs. You should also:
? Familiarise yourself with how to shut off gas, electricity and water supplies and keep a list of useful contact numbers handy
? Consider flood protection products that could help to reduce the impact of flooding on your property and ensure your insurance provides adequate cover for flood damage.
Reducing the likelihood of flooding on farm
? Managing a flood is one thing, but reducing the likelihood of it happening is another. Here are some tips for farmers to consider, to reduce the risk of flooding on your farm:
? Loosen the soil to leave a rough surface after harvesting to allow more water to soak in rather than run off land
? Remove stock when soils are wet in high-risk fields
Is there any solution to Mumbai?s water woes?
Over the years, experts have suggested several solutions to prevent waterlogging during rains in Mumbai. These include rainwater harvesting, widening and deepening of drains, complete ban on plastic bags at the manufacturers? level itself and clearing of encroachment along the banks of Mithi river.
We as responsible citizens should help the BMC and all other civic bodies to reduce the wastes generated that chokes the drains resulting in floods
