Global & natural idea of pesticide reduction - Go green.

A study by researchers from Michigan State University (MSU) has determined that farmers who have taken proactive steps to increase the number of birds and other vertebrates on their land have been able to increase their crop yields, decrease their use of chemical pesticides, and provide a safe haven for endangered species. The study was published in the journal Agriculture, Ecosystems and Environment.

Pesticide and chemicals in our crops are so devastating nowadays and the major problem of current agriculture. Numerous organic and inorganic ways are accepted to deal with the situation that is going to deteriorate the current ecosystem.Pesticides are so harmful that they enter the food chain and disturbes the flora and fauna and thus creating imbalance in the natural environment.One or the other ideas has been accepted in our day to day life to get rid of the problem but the new research has found most natural way to deal with which is going to benefit both the nature and mankind.

A study published in the journal Nature in 2013, found that pesticides cause “broad biodiversity loss,” damaging the habitats of invertebrates like mayflies and dragonflies in soil and streams, even when farmers stick to “safe levels.”

“Our review of research shows that vertebrates consume numerous crop pests and reduce crop damage, which is a key ecosystem service,” noted Catherine Lindell, an MSU integrative biologist and the study’s lead author. “These pest-consuming vertebrates can be attracted to agricultural areas through several landscape enhancements.”

The same research team earlier conducted a study in which they successfully lured American kestrels to some of Michigan’s cherry orchards and blueberry fields by installing nest boxes in strategic places. Kestrels hunt many of the species that cause the most harm on these types of farms, including European starlings, rodents and grasshoppers. They also chase away other smaller birds that damage fruit in cherry orchards.

This movement towards utilizing nature to increase crop yields is bearing fruit around the globe. (Related: Natural bacteria, fungi, found in plants boost crop yields without pesticides.)

In Indonesia, for example, farmers have been able to document increased cacao yields of 290 pounds – worth $300 – per acre. They have done this by encouraging more birds and bats to make their homes on their farms.

In Spain, farmers erect roosts close to rice paddies, increasing the local bat population, thereby reducing the need for chemical pesticides by reducing pests naturally.

Jamaican farmers actively encourage birds in their fields, which in turn eat pests that destroys coffee crops. This has enabled them to save between $18 and $126 per acre, each year.

Farmers in New Zealand have taken this a step further, not only reducing the need for pesticides and increasing crop yields, but in so doing, protecting their only falcon species, which is endangered. Farmers have collaborated with the Marlborough Falcon Trust to reestablish these birds in grape-growing regions of the country, protecting their vineyards and the birds at the same time – a mutually beneficial arrangement for the farmers and the environment.

“These scientists have demonstrated a win-win situation for farmers and birds,” said Betsy Von Holle, a director with the program that funded the MSU research. “Increasing native predatory birds in agricultural areas can help control insect pests that damage crops, potentially reducing costly pesticide use. For declining bird species, these efforts can increase the birds’ reproductive success while producing fruit crops attractive to consumers.”

The MSU team hopes that there will be “broad interest” shown by both farmers and environmentalists in refining and implementing these types of programs more comprehensively throughout the country.
