To keep the heat in the heat wave, it can facilitate water the trees

Heating waves They belong to the world Youngest Weather threats. There is a huge number of people every year killed by thermal stress And it can worsen health problems such as Diabetes, asthma and heart disease.

Unfortunately, bitumens, brick and concrete constructions as well as roof tiles in cities can absorb and keep huge amounts of heat, most of which are released after the sun. It creates so -called Urban Heat Island Effect. In fact, temperatures can be much higher in cities than in Surrounding or rural areas.

Trees and Greenspace can Bring urban temperatures – But they must be able to draw water from the soil to achieve these massive cooling effects.

In other words, sometimes watering trees can be helpful during a heat wave.

Trees must have access to water in the soil to achieve transpiration.

When the trees keep us in the frigid (and no, it’s not just a shadow)

Trees reduce city temperatures in two significant ways. One is because of them, and the other through their cooling effect – and not, are not the same.

The water is taken with the facilitate of the plant’s roots, moves through the stems or trunks, and then closes into the air from the leaves through compact holes called the denta. This is called transpiration and helps to frosty the air around the leaves.

The diagram shows how the transpiration happens.

Water can also evaporate from soil and other surfaces. The combined loss of water from plants and soil is called evapotranspiaration.

Ewapotranspiration cooling effects are different, but they are 4 ° C.depending on other environmental factors.

Watering trees

If the heat waves occur in generally heated, arid weather, then the trees will provide shade – but some may fight transpiration if the soil is too arid.

This can reduce the effect of cooling trees. Maintaining soil moisture and plants irrigation can change this.

The best time for irrigation is early in the morning, because water is less likely that it quickly evaporates before the passage.

You don’t have to make deep water; Most of the absorbing roots are close to the surface, so a bit of miniature irrigation often happens. You can also recycled water from the shower. Using litter helps to imprison water in the soil, giving roots time to absorb it before evaporation.

All transmission plants affect the cooling on the surrounding air, so you may wonder if the trees have something special to offer in terms of the effect and waves of urban heat.

Their huge size means that they provide much larger shade areas than other plants, and if they pass, there are greater cooling effects.

The surface of trees, which is crucial for steam cooling, which takes place on their surfaces, is also much larger than many other plants.

Another advantage is that trees can be very long. They Provide shade, cooling and other benefits For a very long time and at relatively low costs.

Not all trees

To say, I do not want to overestimate the role of city trees in thermal waves when the soil is arid.

Some trees will stop early when the soils are dried, but Others will last Until they wither.

The final choice of a tree can facilitate maximize the cooling effects City Forest. Trees matching local soil and can cope with some drying while maintaining transpiration, can ensure greater cooling

And of course it is crucial to follow all Water limitation rules Or guidelines This can work in your area at this time.

The trees keep us placid

Despite the clear benefits that trees can ensure heat limitation, the number of trees and the canopy covers every year in many Australian cities.

Housing development still occurs without proper consideration of how trees and greenery improve the quality of life of the inhabitants.

This is not an argument. Thanks to the appropriate planning, you can have both a recent housing and a good canopy cover.

We should also be careful excessively favorable City trees.

Trees cannot eliminate the effects of thermal waves, but can alleviate some of them.

Everything we can do to alleviate the effect of the urban heat island and maintain our cities and cooler towns, reduce diseases related to heat and associated medical costs.
