The Reality of Organic Food

We always see the sign in the produce section of our grocery stores: “organic”. Is it truly healthier than conventional produce? In recent years, the push to produce naturally grown foods has increased to boost the health of society as a whole. The term “organic” is thrown around to define foods grown with natural rather than synthetic pesticides and fertilizers but that doesn’t necessarily mean it’s a better alternative.

It is true that organic farms have 97% less synthetic pesticides than conventional farms, but that 3% is still there. This amount is brought to organic farms via wind transport and river runoff. Although synthetic pesticides are more spoken about, they aren’t the only potentially harmful compounds in our fruits and vegetables. Naturally, plants produce pesticides used to protect them from predators. These pesticides are found to be carcinogenic in rats and may be harmful to humans. Synthetic pesticides may actually reduce the production of the naturally occurring plant pesticides which leads to conventionally grown produce having lower levels of it than organic produce. Natural pesticides are found 10,000 times more than synthetic pesticides in both organic and inorganic foods. Moreover, the use of fertilizers in cultivation is essential in plant growth. Naturally occurring phosphate rock is used as a fertilizer in organic farming rather than synthetic fertilizers. The organic fertilizers actually contain more Cadmium, a known carcinogen, than synthetic fertilizers.

With all this research into how many synthetic vs organic compounds are used in the production of our food, it seems like either way, we re ingesting harmful chemicals every day.  Because the risks associated with synthetic pesticides have been more studied than organic pesticides, we are swayed into believing that organic foods are completely healthy. Without knowing the risks attached with organic pesticides and fertilizers, society does not know the full extent of the benefits and drawbacks of consuming organic foods. So before paying the extra couple of dollars for the foods with the organic label, it’s really worth your time to step back and think about what “organic” really means.

Can adding native pollinators increase small-farm yields in under-developed countries?

Small-farms in developing countries from Africa, Asian and Latin America that are struggling with their amount of crop production need a little boost to help get them back to their normal yield. Could the addition of native pollinators be what small-farms need to increase their yield gap?

Before I get into this, let’s refresh our knowledge about pollination.

Pollinators such as honey bees, beetles, and wasps help plants reproduce, which means they play a crucial role in agriculture.

How do they do this?

The main function of pollen is to produce male sperm cells. Pollination basically occurs when pollen is transferred to female reproductive organs of plants which allows fertilization and reproduction to occur. Native pollinators such as the few listed above are able to enhance pollination which helps out farmers with their crops.

Here is a video by Laura Klahre on TEDx Talks that discusses the different types of bees that are effective pollinators.

If pollinators are able to do this, then could these native pollinators effectively help struggling farmers with their yield?

A recent study discusses the effectiveness of implementing new pollinators to help small-farms that are struggling with crop production. It was done on “344 fields from 33 pollinator-dependant crop systems in small and large farms from Africa, Asia, and Latin America”. This study greatly affects under-developed countries that are reliant on their small-farms for food.

The study found that incorporating the new pollinators could potentially close the yield gap of farms by about a quarter; the yield gap being closed by a quarter was found on small fields that were less than 2 hectares.

The study suggests that ecological intensification or a “biodiversity of pollinators” will improve yield outcomes for the farms of these under-developed countries. Biodiversity of pollinators are just means to incorporate a diversity of different pollinators into the farms.

Introducing pollinators has shown to have a positive effect on these farms. It could be the method that struggling small-farms use to help get their farms a higher yield, so why not give it a chance?
