Under-Utilised Food Plants

How Good Is Your Food ?

30% of the world’s population are suffering disease and malnutrition. Most suffer malnutrition whilst surrounded by nutritious food plants. Some drive past perfectly good food plants on our way to the shops to buy less-fresh foods. (Did you know there are thousands of edible and nutritious flowers?)

Malnutrition is a global issue

nutrient_rich_saladNew studies reveal powerful revelations about nutrition and food choices. We celebrate discoveries like ‘1 taro leaf can give enough good food to feed 3 children.’

But let’s be honest about malnutrition. This is not a third-world issue. In fact, coupled with the obesity epidemic, malnutrition could be worse in the developed nations.

It’s all about recognising a good food source when we see it.  Bruce French, founder of Food Plants Int [FPI], first noticed this disconnect in Papua New Guinea.

“It wasn’t that the locals didn’t know anything about their food plants, but there were clearly a lot more edible plants than were readily recognised” Bruce writes.

There are now some comprehensive research databases about food plants. Plants For a Future and Neglected Underutilized Species Scientific organisation have also set out to document the food plants worldwide and run international conferences.

GMO’s Can Give A Great Big Bundle of Nothing

Modern agriculture measures success by volume and not by nutritional value. And so, mechanised farming is geared to maximise the yield. Industrial farming needs predictability and conformity yet healthy societies need variety and nutrition.

Bruce French said “when we breed for yield we get a great big bundle of nothing”.  If we want to get more than just nutrient-depleted fibre, we need to look to food species that grow happily in our bio-region and use farming techniques that care for the soil.  Crops for a future based in Malaysia researches the effects of different cropping systems and under-utilised food species.

Let Us Eat Weeds

Bruce met a woman in Cambodia who was weeding out Momienh (Cleome gynandra). She said, “Everyone else tells me it’s a weed. They say pull it out to grow some cabbages and lettuces.” Bruce told her “Momienh is far more nutritious than western vegetables.” She was so pleased. She said, “No-one’s ever told me that before. I didn’t know. I thought it was just a local plant that was very unimportant.”

In her presentation on secrets of humble plants, botanist Gurib-Fakim shows how weeds can feed and provide medicines.

Grounds For Good Food

World Bank & UN stated that Genetic Modified crops, aiming for higher yeild, are not the way to address world hunger. What we do need is to maintain healthy soils.  Intelligent and educated farming can preserve the nutrients. Healthy Soil  a living, dynamic system.  We now know that the old subsistence farming method of ‘slashing and burning’ destroys the natural fertiliser. Nitrogen and Sulfur are lost – going up with the smoke. Only potash is left.  There is no quick answer. The methods need to fit the situation. But the best step is education. When we make nutrition our goal, we find ways to hold nutrients in the soil, in our food and cycled it back with care.

Bring in the evergreen revolution. Permaculture design invests in sustainable food growing practices in it’s ethics to care for people and care for the environment.

Still Not Digging It

No-dig gardening is not just the easiest way to convert compacted crusty sub-soil to lush gardens full of food. Nor was it simply the best way for us to combat an acre of vigorous grasses that grow more than 2 meters high up and over our young trees. On a global scale, No-dig gardening is the best way to grow food without releasing any carbon into the atmosphere.

Martin Crawford understands the power of no-dig gardening in his food forest. He has a beaut book Creating a Forest Garden: Working with Nature to Grow Edible Crops”

Learn more here about the no-dig gardening method we used over the past 20 years to build our food forest.

The no-dig garden made with cardboard provides:

  1. protection from erosion for the soil
  2. moisture trapping (if laid carefully in reverse-tile pattern).
  3. evaporation barrier
  4. carbon and organic matter
  5. worm-food
  6. composting of a waste that is often sent to landfill
  7. weed-control and conversion to worm-food
  8. food without killing soil micro-organisms
  9. habitat for soil fungi

On the down-side we do need to be careful to remove all plastic-wrap, ties and tape attached to the cardboard as this is a real threat to small animals and reptiles.

How A Weed Succeeds

Weeds venture where other plants fail to go.

They quickly colonise places where something has changed the landscape. The landscape change is usually done by conventional farming methods sucvegies growing in old chook run with composted lawn clippings as mulchh as digging but it could be from a catastrophe such as flood 0r landslip.  The weeds are well adapted to a short life and are highly re-productive with little dependence on the quality of the soil or water supply. Before you remove the weeds have a succession plan. Permaculture deals in modelling systems and seeing what the surrounding landscape has as a plan.  In a rainforest the succession plan involves plants that are happy to start in deep shade and will suddenly rise to the occasion when a mature tree falls.

What Weeds Are Good At

Weeds are excellent adapters. They can mine the on-site resources better than most other plants.  Weeds will mine minerals, sop up excess nutrients on a site and cover bare ground which builds organic matter in the soil.  If you remove a weed, you need to plant something almost just as strong or have a plan to nurture the next plant. There are easy ways to nurture plants, dig swales to bring water to them, cover the surrounding soil with mulch and build a tent of leafless branches to protect plants from too much sun, frost or animal damage and keep a regularly watch on young plantings.

Plan For A Time After The Weeds

When we remove a weed and send it away we are losing minerals and fertility from our site.  If we slash a weed before it goes to seed we get the benefit of the mineral rich organic matter as mulch.  When we do nothing and let weeds and non-edibles rule our site we miss out on the opportunity of having a balanced diet of fresh food and herbs.  Enjoy outsmarting a weed and implement a natural succession plan for a fruitful forest.  Living mulch is ideal to stop future weed invasion especially if it is edible.
