Restoring the strength of soils using natural elements

Spotted: After decades of the intensification of farming, and the ensuing harm it has caused to environments, growers and policy makers are beginning to more seriously consider regenerative farming as the means of achieving a carbon-neutral future. Regenerative agriculture focuses on soil health and a circular agricultural economy, where resources are used in harmony with the natural environment. And, the World Economic Forum (WEF) estimates that farming regeneratively on 40 per cent of the world’s cropland would save around 600 million tonnes of emissions. 

The challenge is the slow pace of change. Regenerative agriculture must scale more quickly in order to cover 40 per cent of global cropland by 2030. Changing soil health can take years, so French agrobiotechnology company Gaïago has created a suite of products designed to help growers make faster improvements to their land. 

Using organic elements that plants already use, such as hydrogen, proteins, and fungi, Gaïago’s products encourage the fertility of the soil and therefore the growing environment of crops. Nutrigeo is a soil prebiotic that stimulates the growth of humidifying fungi. Two different probiotics provide additional nitrogen to the roots, and a foliar prebiotic, Stimulus, supports plants in resisting environmental stressors.  

And for the plants themselves, Gaïago created Vitam’in, a prebiotic for seeds that boosts general vigour at germination to help maximise full genetic growth. Improvements in the fertility of soil can be seen in as little as six months, and when integrated into a regenerative style of farming, will have long term environmental health and biodiversity benefits.  

Other ways in which Springwise is spotting agriculture creating more healthful growing environments include plant patches that monitor stress and eco-friendly insect treatments that do not harm pollinators.

A modular system of 3D-printed bricks for restoring reefs

Spotted: Less than 45 per cent of original global reefs remain, and scientists predict that by 2070, they could disappear altogether. Reefs are declining at twice the pace of rainforests and stopping the damage requires swift, focused actions at sites around the world. One company, Swiss-based Rrreefs, creates bespoke coral reef replacements that provide multiple environmental benefits. The company’s goal is to revive one per cent of coastal coral reefs by 2033.

Using pure clay, the company 3D prints reef bricks that are customised to best suit the nearest shoreline and local environment. By understanding water flows and marine topography, the company builds structures that provide microenvironments for thousands of animals and plants to thrive. Protecting shores from erosion improves the growing environments for underwater forests of mangroves and seagrass, both of which are crucial to the capture of carbon dioxide. And a single cubic metre of the reef blocks provides a new home to more than 20,000 tiny animals, 20 corals, 60 fish, and more.  

The surface of the bricks is designed specifically to support a variety of coral larvae contributing to the genetic diversity of the new reef. The natural clay material contains no artificial ingredients or chemicals, making it a healthy choice that contributes no new pollution to the world’s oceans.  

Using 3D printing allows for modular production and complete customisation of height, width, and length of the overall reef structure. The process also allows for local manufacturing, which further reduces the carbon footprint of each reef.  

The innovations seeking to help stop the irreversible destruction of the world’s coral reefs are many and varied. Recent ones spotted by Springwise include a global cat food brand supporting new reefs and a company making leather out of an invasive fish that threatens reef health.
