Farming for Nature - How mimicking natural processes can feed our planet

PictureCattle in a Silvopasture grazing system (13)

​Current intensive livestock grazing practices have a significant negative effect on vegetation growth and diversity in various ecosystems throughout the world (1). Heavy grazing leads to a consistent decrease in the alpha diversity of plant groups; the number of distinct species in an area (2). Decreasing plant diversity contributes to the unprecedented loss of biodiversity we are currently seeing throughout the world, a significant issue encompassed by UN sustainability goal 15; Life on land (3). Intensive livestock grazing plays a key role in the degradation of fertile land, affecting the food security and ecosystem services of one billion people worldwide (4).  Additionally, intensive livestock grazing releases stored soil carbon as carbon dioxide (5).

Animal products provide all the essential amino acids as well as a dense store of proteins and fat required for human health (6). One billon people around the world rely on animal products for their survival (7). How do we balance these nutritional benefits and the demand they create with the undeniable impact livestock have on our planet?

Regenerative agriculture may be the solution.

Regenerative agriculture is described as “farming and grazing practices that….reverse…. reverse climate change by rebuilding soil organic matter and restoring degraded soil biodiversity…” (8). These practices have three main effects:

Sequestering carbon from the atmosphere and locking it within the soil (8).

Increasing the water storage capacity and percolation properties of soil which results in healthier and more sustainable groundwater catchments (8).

Increasing biodiversity in the soil and on the surface (8).

Central to the concept of regenerative agriculture are the processes of silvopasture, holistic planned grazing, and agroecology (8). These processes integrate grazing livestock with biodiverse landscapes comprising both trees and managed grasslands, mimicking how grazing herds used to migrate across major grasslands such as the American mid-west and the South African veld (9).
​

Combining animals and crop systems may sound like a recipe for disaster, however, it has an excellent ecological basis following the hypothesis of intermediate disturbance. This states that achieving the highest levels of biodiversity in an ecosystem requires an intermediate intensity disturbance at an intermediate frequency for an intermediate period of time (10). This means that an ecosystem will function best when there is enough disturbance to create opportunities for new growth and the filling of niches, but not so much disturbance that the ecosystem is stripped of its life completely. In the South African veld this is achieved through maintaining dense herds of cattle that are moving constantly, mimicking the migration of large grazing herds in the area, thus maintaining the ecosystem (9).

Here in New Zealand, where almost 50% of our emissions come from the agricultural sector (11), regenerative agriculture may provide the solution we have been looking for. Already a movement has begun lead by Mangarara station in the Hawkes Bay who have turned their farm into a biodiverse landscape whilst still running sheep, cattle and poultry (12). If we can learn from nature and follow the example set by places such as Mangarara station then the future of New Zealand’s, and the World’s, food security and ecosystem integrity can be secured.

Two Brothers and a Cousin fresh off walking the Camino de Santiago were searching for their next steps in life. After being in the wilderness for over a month, there was a certain level of excitement when presented with a business proposition involving nature and giving back to the environment. It was also a great time to give this a go as Oderings had just closed down leaving only Mitre 10 Mega as the sole plant provider within Upper Hutt. With a quick visit to inspect the potential produce that we would buy we were blown away with their quality. leveraging off the old mans years of experience we were convinced this would work. Let the first of many road trips commence...
Picture
Once we arrived at our destination we got straight to work bundling and trimming our first bunch of maples and magnolias and packing them onto the back of a trailer...
Picture
We quickly realised this would not be completed in a single day and after getting home at 2 am, healing in the plants till 3 am, we were back off on another road trip at 5:30 am to get the second lot of trees.... 
Picture
The following months were spent bagging up roughly 2000 trees and building the first of our irrigation lines. It was during this part of the process that we realised just how much plastic is used in the nursery/garden center industry. We wanted to change this as much as we could and since then this has been one of our main drivers.

    As a local New Zealand family owned and operated business we are proud ensure D.I.Y is kept in our DNA as can be seen when walking through the Gardens, Nursery and Garden Center. Never ones to let a hard tasks pass us by we tackle them head on and learn as much as we can as fast as we can to try and create a positive change and encourage people to fall in love with the outdoors again.
