Sustainability & Environment

Figures on global data availability and growth are staggering. Data are expected to grow by an astounding factor of 300 between 2005 and 2020, and are predicted to reach 40 trillion bytes by 2020. This creates significant opportunities for data-based decision-making in industries such as agriculture.

Indeed, ongoing developments in precision agriculture and web-based apps can help the farmer to greatly enhance their efficiency, productivity and sustainability, and to prepare themselves for potentially catastrophic climatic events in real time.

On the other hand, farmers have traditionally relied on a more conventional approach for monitoring and improving their performance, namely, benchmarking. In a nutshell, benchmarking is about comparing one’s performance to that of their peers in terms of one or more performance indicators, typically expressed as ratios – i.e. output over input.

For instance, a dairy farmer may want to know how far their milk production per cow is from the top 10% of farms, or whether farms with a different management strategy than theirs (e.g. pasture-based farm vs. all-year housed system) could deliver higher milk yields. Farm benchmarking reports are standard practice in agricultural extension and consultancy.

However, these reports can be overly simplistic, because partial performance ratios cannot capture the multifaceted nature of agricultural sustainability, encompassing environmental (e.g. carbon footprints), social (e.g. labour use) and other indicators (e.g. animal health and welfare), in addition to economic and technical ones.

Agrifood

A world with a rapidly increasing population needs a rapidly increasing food supply. However, with a limited amount of land to work with, farmers must maximise agricultural production on the land they have available.

Modern-day intensive agriculture techniques include mechanical ploughing, chemical fertilisers, plant growth regulators, pesticides, biotech, and genetic modification.


1. Crop production has rapidly expanded in the past few centuries

Worldwide, the amount of cultivated land increased 466% between 1700 and 1980, with global food production doubling four times between 1820 and 1975. In 1940, the average farmworker supplied 11 consumers; in 2006, each supplied 144 customers. Two out of five American labourers were farmers in 1900, but now only one in 50 work in agriculture. In 1830, five acres of wheat took 250-300 hours of work to produce. By 1975, it only took 3¾ hours.


2. Crops can be grown without soil

Using a crop-growing method called hydroponics, instead of putting plants in soil, a mineral solution is pumped around the roots. This makes it possible to grow crops in regions with low-quality soil or none at all, increasing the amount of space that can be used for agriculture. This technique also allows for the nutrients to be effectively recycled and eliminates the risk of soil organisms that cause disease.


3. At least 90% of the soy, cotton, canola, corn, and sugar beets sold in the US are GMOs

Since the 1970s, scientists have been working on genetically modifying crops to make them tougher, disease-resistant, more nutritious, and higher yielding. Though the first commercially available GMO came onto the market just 23 years ago, global markets have already been transformed by the ground-breaking innovation.


4. Regenerative grazing increases the health and productivity of pastures

Regenerative grazing - staggering grazing on different plots of land according to a calendar – has proven to increase soil health. By allowing plots to rest after grazing, the soil and anything living in it is able to recover before the next time it is used. Regenerative grazing cultivates fields with less bare soil and increases populations of earthworms and soil organisms. Not only that, it also eliminates the need for chemical fertiliser, increases grass growth by 14%, and causes a 10% decrease in carbon footprint per litre of milk.
