Farmers spot diseased crops faster with artificial intelligence

At the Fujitsu factory in Japan, a significant decline in demand for semiconductor computer chips meant the company had large empty factory space sitting unused. A new business approach allowed them to dually address both the need to evolve their business model with a global decline of viable agricultural space needed to grow the world's food. Now, the factory houses indoor vegetable gardens, soil free and less resource-heavy than traditional farmland.

The rapid development of emerging economies across Asia and Africa is lifting hundreds of millions of people out of poverty - but there is much debate as to how to best structure this growth. If these economies evolve in the same way as in the West - with unchecked, excessive resource consumption and heavy pollution - the planet may be on the fast track to disaster. Earthrise explores how these nations can grow sustainably using improved, eco-conscious technologies like renewable energy and eco-friendly farming practices.

During the Industrial Revolution, farmers began harvesting monoculture crops which produced promising profits but proved harmful to the soil and weakened the immune capabilities of native plants. Lately, however, permaculture practices have been on the rise amongst farmers to better diversify their yields and reduce reliance on chemicals.

As climate change continues to advance, its impact on farmlands has become more pronounced and increasingly devastating. Farmers and researchers in both South Africa and Nepal are working towards solutions to problems specifically related to climate change. Centered on developing technology, these farmers have found success with NASA satellite imagery as well as local clinics.

To cope with and combat gentrification, residents of Miami's Little Haiti neighborhood created a community garden called the Femme Fairy Garden, founded by Fempower. Community members come together every Sunday to tend to their plants and connect with their neighbors.

Communities across Uganda have been realizing the benefits of agroforestry, an old farming system that mimics natural ecosystems. Apart from creating a diverse, stable local food supply, the practice promotes soil health, bolsters biodiversity, creates wildlife habitat, and sequesters carbon. An NGO is working with communities to spread the practice across the region, with marked effect.

For years, a rancher in Southern Oregon has been trying to keep a local pack of wolves from killing his livestock, and after many rounds of trial and error and collaborative efforts, a high-tech fence may be the solution. Although the fence isn't cheap, many came forward to help make this a possibility and show their support for a project that united people that historically have stood politically opposed.

In Arizona, the use of drones as farming technology is gaining traction. While still in the early stages, drones have shown to help with field mapping and data collection on things like crop conditions, water quality, and infestations. In an area that has been experiencing a 2-decade drought, these drones are able to help identify more precisely the water needed for soil.

As climate changes causes seawater to flood land and increase the salt content in soil, farms in Scotland and the Netherlands are experimenting with using the saltwater to grow food. Seawater Solutions is growing crops called halophytes that have a high-salt tolerance and can be eaten or used as material for cosmetics and biofuels. And the Salt Farm Foundation has shown that potatoes, cabbage, and tomatoes can grow in saltwater. These projects can labor intensive, but seawater irrigation could be a viable climate adaptation solution.

Violent clashes between farmers and cattle herders that have claimed thousands of lives have largely ceased in Otukpo, thanks to a peacekeeping process that resolves disputes and is based on a shared recognition of two groups' humanity. The process imposed rules in an otherwise unruly system in which Fulani herders' open-grazing cattle destroyed crops, leading to violence. Negotiated leases and dispute-resolution mechanisms, governed through monthly meetings, have resulted in only one death since 2018, while surrounding areas continue to suffer many casualties.
