Butterflies and bees need our help. They’re currently dying off due to changes in their environments while also being sprayed with deadly pesticides. A bunch of countries have banned the bee-killing pesticides, but that’s not helpful in the short term for beers or farmers. The progress at the policy level is needed and is slowly being rolled out around the globe.
At the individual level there is already stuff we can do to help the bees and our farming friends. All you have to do is plant some native species that your local pollinators love. Oh, and that means lots of butterflies.
The essence of the technique is to devote one in every four cultivation strips to flowering crops, such as oil seeds and spices. In addition, she provides pollinators with cheap nesting support, such as old wood and beaten soil that ground nesting bees can burrow into. Sunflowers were also planted nearby as wind shelters.
“There is a very low barrier so anyone in even the poorest country can do this. There is no equipment, no technology and only a small investment in seeds. It is very easy. You can demonstrate how to do it with pictures sent on a cellphone.”
Compared with control fields of pure monocultures, “amazing” benefits for farmers and an increase in abundance and diversity of pollinators were found. Crops were pollinated more efficiently, there were fewer pests such as aphids and greenfly, and yields increased in quantity and quality.
