Growing Food with Human Waste

Growing Food with Human Waste

Growing Food with Human Waste is Needed

A few projects are looking at growing food with human waste, including researchers from the Laboratoire Eau Environnement et Systemes Urbains just outside of Paris. They are switching out harmful synthetic fertilizers from being used on their wheat crops to urine-based fertilisers. And they are seeing positive results as the waste-based fertilizers provide organic matter that improves the soil.

Farmers in a small town in Tepetixtla, Mexico, use fertilizer made from human excrement to fertilize their crops. Growing food with human waste requires a composting process used to be hygienic and better for the soil and biodiversity. Moreover, growing food with human waste also saves water and reduces pollution because the excrement isn’t flushed into the sewage system.

In Vermont, the Rich Earth Institute runs a community program that turns human urine into fertilizer. The Institute conducts original research to examine the safety and efficacy of urine-derived fertilizers in agriculture. The program encourages community members to donate their urine to help them further their research. In 2021, 180 people donated their urine to the Rich Earth Institute.

In Kenya, the organization Sanivation developed a fecal sludge treatment plant. The plant can serve 10,000 people and produce 350 tons of fuel per month. This can be used as a cooking and industrial fuel, a sustainable option for charcoal made from fallen trees. Each plant ensures that water is safely managed, creates local employment, prevents environmental pollution and saves trees through their innovative biofuels.

In Switzerland, a company called Sanitation 360 developed a urine cassette that collects, contains, treats and concentrates the urine inside the toilet. The urine is then stabilized, dehydrated, and used directly as a fertilizer. The fertilizer includes the same type and concentration of plant nutrients in commercial fertilizers. By converting urine into a dried fertilizer, the flow of polluting plant nutrients to the environment can be minimized, which can help limit nutrient overload and dead zones in aquatic ecosystems.

Human excrement is one of the world’s most natural things, and it’s a shame that much of it is going to waste. While we may get queasy thinking about fertilizing our crops with human excrement, do we know what is in the currently used fertilizers? What is more natural and less environmentally damaging than something from our bodies? With more organizations and researchers finding new sanitary ways to use human excrement as fertilizers, this may become the new normal and the new way of food production.

Cloud technology could be the most disruptive digital tool for empowering ASEAN’s vulnerable communities

Cloud technology could be the most disruptive digital tool for empowering ASEAN’s vulnerable communities

Cloud technology in Asia Pacific is projected to grow dramatically in the next few years, and plays a crucial role in modernising and empowering communities across the region. But it is not without challenges to ensure its benefits are broadly felt.

Cloud technology plays a crucial role in modernising and empowering communities across Southeast Asia, from boosting financial inclusion to streamlining access to formal markets for smallholder farmers, according to a report by Eco-Business Research launched on Friday (19 March). But multiple stakeholders must collaborate to ensure that there is true democratisation of cloud technology across the region 

Cloud technology – the delivery of on-demand computing services through a network of remote servers – is projected to grow by 117 per cent in Asia Pacific between 2019 and 2024, according to GlobalData with more businesses allotting bigger budgets towards it.

Cloud needs minimal infrastructure and investment while it has the ability for companies to operate at scale quickly making it particularly appealing for emerging economies. 

Nevertheless, the development and adoption of cloud technology vary considerably across the five focus countries studied in the Eco-Buisness report.

Singapore is a leader in cloud adoption and growth potential, which is underpinned by its robust infrastructure and enabling policies. It is ranked top in the Eco-Business Cloud Opportunity Matrix. Its ‘Smart City, Smart Nation’ initiative places heavy focus on cloud technology to enable a more efficient provision of services and to streamline government systems. 

Parking, tax and government platforms allowing you to register births and businesses are powered by cloud technology. “We now have the ability to use data to manage transport systems like never before,” Jamie Leather, chief of Transport Sector Group, Asian Development Bank said in the report.

Thailand and Malaysia are ranked next in the matrix, with conducive regulatory environments and relatively high digital penetration at around 80 per cent of the populations in both countries.

Indonesia, the most populous country in Southeast Asia, and the Philippines still have some way to go, the report noted, with both countries lacking the bedrock digital infrastructure needed to propel cloud technology. 

Nevertheless, Indonesia is one to watch as it is one of the fastest growing markets for cloud computing, with a thriving digital start-up industry boasting companies such as multi-service platform and digital payment group, Gojek and e-commerce company, Tokopedia.   

Growing pains are to be expected as digital infrastructure, awareness and enabling policies develop alongside the uptake of cloud technology.

“Everyone is still on this journey, no-one has a solution for best practice,” said Calum Handforth during a panel discussion launching the paper, and who advises on smart cities and digitalisation for the United Nations Development Programme

 

Breaches in data privacy are a headache for both public and private sector entities and could undermine the adoption of cloud technology, despite most providers having robust security systems in place, the report saidSingapore’s digital success story is marred by serious data breaches including one in 2018 when hackers accessed 1.5 million medical records, including those of Prime Minister Lee Hsien Loong. 

“Governments are upskilling their ability to understand the discussions around privacy and security,” May Ann Lim, executive director of Asia Cloud Computing Association, said in the report.  

Cloud technology is in a strong position to be a “force for good” the report said, enabling collaborative cross-border efforts to cohesively deal with cybercrime. However, borders must stay open to allow cloudtech to maximise on trade and economic opportunities. The report suggests the creation of a “common set of principles governing cross-border data flows” will boost economic competitiveness collectively as a region.

The report said that the digital divide is a major impediment to cloud technology. Some in Southeast Asia are being left behind in the race to digitise with stuttering power supply and unstable internet provision in developing markets including the Philippines and Indonesia. 

Even in markets with high internet provision, “policymakers and digital service providers need to address the disparity between different segments of society,” the report charged. Meanwhile, improving computer literacy is instrumental in ensuring cloud technology is inclusive of all.  

The report showcases several examples of best-practice in the region. Indonesia has rising potential in using cloud technology to help support and modernise agribusiness. “The farm-to-customer model has also helped the industry address the ongoing problem of multiple middlemen who typically take a 10 to 15 per cent margin each,” according to the report.  

 

There is potential for smallholders to tap into the e-commerce market using cloud-powered apps as the country’s growing middle class opts for online shopping over the traditional open-air ‘wet’ market, Purnama Adil Marataan expert in agribusiness in Indonesia told the panel. Meanwhile, cloud-powered innovations can “make modern farming more inclusive for the smallholder farmer,” Marata added 

Cloud has also played a part in facilitating access to finance for smallholder farmers in Southeast Asia, home to one of the world’s largest unbanked populations. By leapfrogging bricks-and-mortar banking, Indonesia’s farmers, one of the poorest groups in the region that would be ordinarily regarded as high-risk borrowers by traditional financers, can tap into micro-loans as well as agricultural cooperatives where farmers can pool their resources.

“These cloud-enabled lending platforms have also provided farmers with legitimate and safer alternatives to predatory loan sharks,” said the report.

More collaboration is needed in the region to maximise cloud potential. “For this to work, it requires more than just technology…you need to combine it with leadership,” Jane Treadwell from Amazon Web Services said during the panel discussion, whose backlog of experience also includes the digital transformation of governments for the World Bank.

Greater collaboration is needed between government, the private sector, academia and customers to ensure democratisation of the cloud, and that the benefits of this technology can help the most vulnerable people in the region. “Without partnerships, collaborations, we have nothing,” Akanksha Bilani, regional alliance head at Intel told panellists.

Denmark just opened a huge vertical farm, and it could be a sign of things to come globally

Denmark just opened a huge vertical farm, and it could be a sign of things to come globally

When you look at a lush, green, delicious plant, you probably tend to think it comes from a fertile land somewhere in the world. Well, that might no longer be the only option out there. A vertical farm just opened up in an old warehouse without windows in Copenhagen and it expects to produce 1,000 tons of produce per year by 2021, showing that vertical farms really do have a solid future.

They won’t see the light of day or have access to soil, but hundreds of tons of lettuce, herbs, and kale (among other produce) will soon be coming out of the vertical farm. The advantage of the vertical farm is that it takes less space than a conventional crop, helping to meet the world’s food demand and producing food locally instead of importing it.

Around 37% of the earth’s landmass is used for agriculture, according to the World Bank. But climate change and conflicts can challenge the availability of land for farming, not to even mention soil erosion — one of the major environmental issues that often fly under the radar. A quarter of the world’s productive lands have already been degraded, according to the World Food Programme, challenging food security.

The project is run by YesHealth Group, a Taiwanese company with a long record developing vertical farming technology, in partnership with Nordic Harvest, a Danish start-up that wants to use technology to make food production more sustainable. YesHealth already runs in Taiwan the largest vertical farm in China.

It’s not actually a brand-new idea, as vertical farms have been around for almost a decade. They first took in Asia and the United States, which has the world’s biggest vertical farm, located in a steel mill in New Jersey and producing two million pounds of produce every year. But the idea is now also catching up in Europe.

 

“We offer a more sustainable way of producing food year-round, locally, without disturbing nature,” founder of Nordic Harvest, Anders Riemann, told Reuters. “We take some of the food production back into the cities where you can grow in a much smaller land and space-optimized in the height.”

 

The farm is installed in a 7,000 square meter hall and has 14 shelves of greens stacked up toward the ceiling in aluminum boxes. It’s all automated, with robots used to move the shelves into position and stack the produce. When fully operational, the farm will be hermetically sealed to secure the farming conditions.

Water consumption will be between 90% and 95% lower compared to traditional farming. No artificial fertilizers, pesticides, or other toxic chemicals will be used. About 200 tons of produce will be harvested in the first quarter of 2021 but this would reach 1,000 annually when the farm runs at full capacity by end of 2021.

The project also addresses one of the frequent criticism vertical farms have, the fact that they require a vast amount of electricity to provide artificial light — but for Denmark, that won’t be too big of a problem. The farm uses 20,000 specialized LEDs lightbulbs, manufactured by YesHealth, that are powered by renewable energy from Denmark’s extensive wind farms.

 

“A vertical farm is characterized by not harming the environment by recycling all the water and nutrition or fertilizer,” said Riemann. “In our case, we use 100% energy from windmills which makes us CO2-neutral.”

 

Denmark reported record-breaking wind power in 2019, covering 47% of the country’s electricity demands for the entire year. Out of the 47%, most came from onshore (29%), although offshore also generated a healthy amount (18%). The country expects to keep expanding renewables as a way to reduce its emissions.

Environment to benefit from ‘biggest farming shake-up in 50 years’

Environment to benefit from ‘biggest farming shake-up in 50 years’

Wildlife, nature and the climate will benefit from the biggest shake-up in farming policy in England for 50 years, according to government plans.

The £1.6bn subsidy farmers receive every year for simply owning or renting land will be phased out by 2028, with the funds used instead to pay them to restore wild habitats, create new woodlands, boost soils and cut pesticide use.

The wealthiest farmers – those receiving annual payments over £150,000 a year – will face the sharpest cuts, starting with 25% in 2021. Those receiving less than £30,000 will see a 5% cut next year.

Some of the biggest recipients of the existing scheme have been the Duke of Westminster, the inventor Sir James Dyson, racehorse owner Prince Khalid bin Abdullah al Saud and the Queen.

Farmers will also get grants to improve productivity and animal welfare, including new robotic equipment. The goal of the plan is that farmers will – within seven years – be producing healthy and profitable food in a sustainable way and without subsidies.

The environment secretary, George Eustice, acknowledged the damage done to the environment by industrial farming since the 1960s and said the new plans would deliver for nature and help fight the climate crisis. Farming occupies 70% of England, is the biggest driver of biodiversity loss and produces significant greenhouse gas emissions and water pollution.

The radical changes in agricultural policy are possible due to the UK leaving the EU, whose common agricultural policy is widely regarded as a disaster for nature and even critics of Brexit see the changes as positive.

Farming and environment groups largely welcomed the plans but said more detail was urgently required. Brexit is looming at the end of December and uncertainties remain over food tariffs and trade deals. Many groups are also concerned about the potential import of food produced to lower animal welfare and environmental standards.

“[This is] the biggest change in agricultural policy in half a century,” said Eustice. “It makes no sense to subsidise land ownership and tenure where the largest subsidy payments often go to the wealthiest landowners.

“Over the last century, much of our wildlife-rich habitat has been lost, and many species are in long-term decline.

“I know many farmers feel this loss keenly and are taking measures to reverse this decline. But we cannot deny that the intensification of agriculture since the 1960s has taken its toll. Our plans for future farming must [also] tackle climate change – one of the most urgent challenges facing the world.”

The total of £2.4bn a year currently paid to farmers will remain the same until 2025, as promised in the Conservative manifesto. Currently, two-thirds of this is paid solely for owning land, but the proportion will fall to one-third by 2025 and zero by 2028. Funds for environmental action will rise from a quarter of the total to more than half by 2025, with the remaining funds used to increase productivity.

The new green payments will be trialled with 5,000 farmers before a full launch in 2024. But the level of payments for work such as natural flood defences and restoring peatlands and saltmarshes has not yet been set. Nor has the likely cut in carbon emissions been quantified.

The president of the National Farmers’ Union, Minette Batters, said: “Farming is changing and we look forward to working with ministers and officials to co-create the new schemes.”

But she added: “Expecting farmers to run viable, high-cost farm businesses, continue to produce food and increase their environmental delivery, while phasing out existing support and without a complete replacement scheme for almost three years is high risk and a very big ask.”

The cuts are expected to reduce the income of livestock farmers, for example, by 60% to 80% by 2024, Batters said.

Kate Norgrove, of the WWF, said: “Our farmers have the potential to be frontline heroes in the climate and nature emergency, and this roadmap starts us on the right path. It must see increased investment in nature as a way to tackle climate change.”

Tom Lancaster, principal policy officer for agriculture at the RSPB, said: “This is a make or break moment for the government’s farming reforms, which are so important to both the future of farming and recovery of nature in England. [This plan] provides some welcome clarity, but faster progress is now needed over the coming months.”

But Craig Bennett, CEO of the Wildlife Trusts, said: “We are deeply worried that the pilot [environment] schemes simply cannot deliver the promise that nature will be in a better state. Four years on from the EU referendum, we still lack the detail and clarity on how farm funding will benefit the public.”

Other measures in the government plan include funding improvements in how farmers manage animal manure – slurry is a major polluter of both water and air – and a scheme where farmers seeking to leave the sector can cash out all the subsidies payments they are due up to 2028 in 2022, part of efforts to help new farmers enter the sector.

The government said it would be cutting “red tape” for farmers, with warning letters replacing automatic fines for minor issues and more targeted – though not fewer – inspections.

In July, the government said rules about growing diverse crops, fallow land and hedges would be abolished in 2021, claiming they had little environmental benefit. Farming policy is a devolved matter and other UK nations have yet to bring forward firm new plans.

Green Party plan for regenerative farming to start from the grassroots

Green Party plan for regenerative farming to start from the grassroots

The success of a Nelson organic community garden is a blueprint the Green Party hopes to replicate throughout the country.

Green Party co-leader James Shaw was in Nelson on Saturday, where he visited the Waimarama Community Garden to talk about his party’s policy for sustainable and regenerative farming.

A week ago the Greens launched their Future of Farming plan, which pledged $297m to support farmers and growers to transition to more environmentally-friendly farming practices.

Along with that was $10m for community food production projects, similar to the one at Waimarama.

Run by volunteers, the Waimarama Community Garden specialises in organic produce, seeds and compost, and provides garden space and educational workshops for the public.

Shaw said Nelson was at the forefront of efforts to increase food resiliency and support community food production.

“This will be one of those examples that will be used around the country, for the kinds of community composting and regenerative farming examples we want to see more of.

“The idea is to scale up this kind of work here in Nelson and right around the country so communities, households and local businesses can get involved in processing their own food waste, turning it into high quality compost and then turning that into sustainable food grown locally.”

Shaw said while the plan was a practical way of reducing food waste and providing high-quality sustainable food for low-income families, there was also an educational component as well.

“It means that people who don’t normally have the opportunity to think about where food comes from, they get connected to that system and become more conscious about the waste they produce in their homes and businesses.”

Shaw said while an exact delivery method of the money had not been set out, if passed the $10m would go a long way.

“[Community gardens] do run on the smell of an oily rag – that funding should give the whole sector a shot in the arm.

“If we can get the funding over the line… it will provide a real boost to initiatives like [Waimarama], who are doing such good work and are such a good example to the rest of the country.”

Speaking on the party’s broader farming plan, Shaw said the $300m investment would help remove the financial barriers for farmers to transition to more environmentally sustainable practices.

Some of these changes would include tightening the limits on nitrogen fertilisers, and banning the import of palm kernel as a stock feed.

“We know farmers are really proud of the land and have a deep connection to the land,” Shaw said.

“A lot of farmers are stuck in a hamster wheel. They’re highly indebted, they want to move towards more sustainable models of farming and food production, but are stuck.”
