Earth, Air, Fire, Water

I am Earth:
Grounded and mounded
And moulded in clay
Secret and shrouded
And hidden from day

Womb am I:
Life is seeded and sprouted
And spread out in green
I am fertile and febrile –
The guardian unseen

I am Air:
Wispy and misty
And swirling in space
Fleeting and flirting
And moving with grace

Breath am I:
Life is shaped and spoken
And scattered in white
I am ethereal, inspiring –
The guardian of flight

I am Water:
Flowing and knowing
And fresh with surprise
Snaking and slaking
And shifting disguise

Thirst am I:
Life is suckled and sated
And swaddled in blue
I am replenishing, forgiving –
The guardian of new

I am Fire:
Burning and yearning
And purging the night
Forging and flashing
And shedding all light

Heat am I:
Life is sparked and stoked
And flame-licked in gold
I am passion, transcendence
The guardian of soul

We are Earth, we are Air
We are Water and Fire
And the mission we share
Is to quench life’s desire

The message we bring
Is the wisdom we keep:
That we four merge to one
In the love that you seek

Meeting water and energy challenges in agri-food sector with technology

Meeting water and energy challenges in agri-food sector with technology

Article by Wayne Visser

Part of the Sustainable Innovation & Technology series for The Guardian.

Innovations in sugar cane processing to reduce water use and produce energy will help to meet future agricultural product demands

Worldwide, the overall growth in demand for agricultural products will require a 140% increase in the supply of water over the next 20 years compared to the past 20 years. While the bulk of this demand will be from irrigation, food processing plants can also be water intensive. So, any technological innovations in the industry that save water are welcome.

One such innovation is by Mars Petcare, which has developed a recirculation system that reduces the potable water used for cooling in its pet food production process by 95%. Wastewater is also down by 95% and gas by 35% through the use of a treatment method that keeps the water microbiologically stable.

In Brazil, water used in sugar cane processing has gone down from 5.6 to 1.83 cubic metres (m3) per tonne in recent years, due to improved technologies and practices in waste water treatment.

Further reductions can be made by replacing the standard wet cane washing process with a new technique of dry cane washing. Costa Rican company Azucarera El Viejo SA has found that this switch has resulted in more than 6m gallons of water being saved each day during the harvest season, netting savings of approximately $54,000 (£32,000).

Of course, in food processing, it is not only volume of water that is important, but also the quality of water effluent associated with the manufacturing process. In Brazil, sugar cane is partly processed into ethanol. Vinasse is a byproduct of this process that pollutes water. Technological innovation shows that, while in Brazil emissions of 10-12 litres of vinasse per litre of ethanol are standard, levels of 6 litres can be achieved.

Other examples of innovative water quality solutions in the agri-foods sector are Briter-Water, which has been piloted in the EU and uses intensified bamboo-based phytoremediation for treating dairy and other food industry effluent; and the Vertical Green Biobed, developed by HEPIA, a school from the University of Applied Sciences of western Switzerland, to improve water treatment of agricultural effluents.

Generating energy from agricultural waste

Besides water issues, agriculture is also very energy intensive, accounting for 7% of the world’s greenhouse gas emissions, according to 2010 figures. Even carbon emissions associated only with direct energy use by the sector stand at 1.4% of the world’s total. Energy efficiency technologies will certainly help, but there is an equally big innovation opportunity in generating energy from agricultural waste.

It is estimated that the global biofuels market could double to $185.3bn (£110.5) by 2021 and that next generation sugar cane bagasse-to-biofuels technologies could expand ethanol production in key markets like Brazil and India by 35% without land or water intensification. Experiences in this rapidly growing industry suggest some lessons which can be applied to sustainable technology innovation more generally.

Lesson 1: technologies must be ready-for-market

There are always competing technological solutions at the Research and Development (R&D) phase, but a critical test is which ones are ready to scale commercially. In the case of cellulosic biofuel technologies, despite early research into wheat straw and corn stover, sugar cane biomass ended up being more commercially attractive to big investors like Blue Sugars, Novozymes, Iogen, Beta Renewables, DSM and Codexis.

Lesson 2: partnership is critical for success

There have been few standalone projects announced. Instead, technology companies from the US and the EU have generally teamed up with large aggregators of bagasse like Raizen and Petrobras. Apart from technology transfer benefits, access to already-aggregated bagasse is economically essential.

Lesson 3: policy support and market demand attract investment

Brazil is especially attractive as a technology transfer destination due to a combination of policy certainty and strong ethanol demand. This combination is also stimulating parallel next generation biofuels. Most notably GraalBio and Praj have significant projects targeting other feedstocks such as straw.

Investment in biofuels can also generate significant economic value for agri-food processors. During the sugar cane harvest, the left over fibre is burned and converted into energy via bagasse-to-biogas production. During the 2011-12 harvest, approximately 38m kWh of energy derived from bagasse-to-biogas production was sold by Azucarera El Viejo to the Costa Rican Electricity Institute, bringing over $3m (£1.79m) of income to the company.

In Nepal, the Biogas Support programme installed over 250,000 domestic biogas plants in rural households between 1992 and 2011, using cattle manure to provide biogas for cooking and lighting, replacing traditional energy sources such as fuel wood, agricultural residue and dung. Besides health benefits from less indoor smoke, the project has cut 625,000t of CO2.

And in Rwanda, there is a proposal – yet to be approved and implemented – for two biofuels companies, Eco-fuels Global and Eco Positive, to invest $250m (£149m) and grow 120m jatropha trees, helping to make Rwanda self-reliant in biodiesel by 2025 and bringing jobs to 122 small oilseed-producing cooperatives with over 12,000 members.

Water Footprints

Water Footprints:

Lessons from Kenya’s floriculture sector

Article by Wayne Visser

An International Sustainable Business column for The Guardian

There are flowers to fit every occasion. But if you are celebrating World Water Week (26-31 August), you might want to think twice. A single rose – grown in Kenya, as many of the world’s cut flowers are – takes around 10 litres of water to produce, with the so-called water footprint, or virtual water export, of Kenya’s floriculture industry having more than doubled over the past 15 years, mostly to supply the Netherlands (69%), the UK (18%) and Germany (7%).

This notion of virtual water – the water embedded in the things that we trade – is gaining visibility as awareness of our global water crisis increases. I remember first getting to grips with the idea a few years ago when I interviewed Fred Pearce, author of When the Rivers Run Dry, for the University of Cambridge Top 50 Sustainability Books project. According to his calculations, to get us through the day, it takes about a hundred times our own weight in water.

Of course, water footprints are not the only impacts we find in our global supply chains. There are issues of labour rights, climate change, transparent governance, biodiversity loss and economic development, to mention but a few. The challenge is to manage and minimise the negative impacts. This is where I believe the example of Kenya’s cut-flower industry can help us to tease out some hard-won lessons, starting with the story behind the Horticultural Ethical Business Initiative (HEBI).

The seeds of the HEBI process were sown in November 1999 when local civil society organisations mounted a successful campaign against workers’ rights violations in Cirio Delmonte, one of Kenya’s largest pineapple growers. The success of this campaign raised concerns in the flower industry, prompting stakeholders to develop the Kenya Standard on Social Accountability and a Voluntary Private Initiative to oversee its implementation.

However, the real impetus for HEBI came from the pressure exerted by transnational alliances of NGOs and consumer groups. The Kenya Women Workers Organisation (KEWWO) was funded by the UK-based Women Working Worldwide (WWW) to gather evidence of the Ethical Trade Initiative Base Code violations. Their report catalogued various unacceptable conditions, from pesticide poisoning to sexual harassment and rape, and spurred a campaign dubbed Produce Safely or Quit. At the same time, the Kenya Human Rights Commission issued a three month ultimatum to flower producers to improve working conditions, failing which they would go international in their campaign.

When the Ethical Trading Initiative (ETI) was alerted to these serious labour rights violations in 2002, several of their corporate and NGO members visited Kenyan flower producers. In fear of losing their most significant market, Kenyan stakeholders came together for the first time to lay the groundwork for the formation of HEBI. What I find particular interesting is that the Horticultural Ethical Business Initiative (HEBI) did not arise from a vacuum of voluntary codes. On the contrary, there were already seven different international ethical codes being applied. However, they seemed to lack effectiveness and credibility …

Tackling the World Water Crisis

Blog by Wayne Visser

Part 11 of 13 in the Age of Responsibility Blog Series for 3BL Media.

About 2.4 billion people live in water-stressed countries, according to a report by the Pacific Institute. Water demand in the next two decades will double in India to 1.5 trillion cubic meters and rise 32% in China to 818 billion cubic meters, according to the 2030 Water Resources Group. China is home to roughly 20% of the world’s population, but has only about 7% of the world’s water. That means there are around 300 million people living in water-scarce areas. According to a World Bank report, water scarcity and pollution reduce China’s gross domestic product by about 2.3%.

When I interviewed Fred Pearce about his book, When the River Runs Dry, he told me that, for the average Westerner to get through the day, it takes about a hundred times their own weight in water – that’s every day; not every year, every day. The water used is mainly to grow the things that we eat. Pearce gave me some of the facts and figures: To grow a kilogram of wheat takes about a ton of water, a kilogram of rice takes more. Once you start feeding grains to livestock to produce meat and dairy products, the numbers are even higher. To produce enough meat for one hamburger takes about 10,000 litres of water, which is about 10 tons. If you are a vegetarian you are not doing too much better because it typically takes 4,000 litres of water to produce one litre of milk.

That’s for food. What about drinks? Coca-Cola sells 1.5 billion beverages a day in over 200 countries and uses about 2.5 litres of water to produce one litre of its products. The company received its water wake up call in 2002, when residents of Plachimada, a village in India’s southern state of Kerala, accused the company’s bottling plant there of depleting and polluting groundwater. Two years later, the local government forced Coke to shut down the plant. In 2006, their situation got worse when a New Delhi research group found high levels of pesticides in Coca-Cola and PepsiCo’s locally produced soft drinks, resulting in several Indian states banning their products. Coke denied any wrongdoing, claiming that bore-hole water fed farming was mainly responsible for lowering the water table and that the pollution claims were unsubstantiated. However, the public perceptions battle had already been lost.

Speaking to Time magazine in 2008, Jeff Seabright, the company’s vice president of environment and water resources, admitted that Coke had mishandled the controversy. ‘If people are perceiving that we’re using water at their expense, that’s not a sustainable operation,’  he said. This realisation resulted in a serious shift in Coke’s strategic positioning of its CSR towards tackling water as priority number one. ‘It’s great that companies used to hand out checks for scholarships or to clean up litter,’ said Seabright, ‘but increasingly the real relevance is using the company’s core competence to address issues that are of societal concern.’ And for Coke and the communities in which it operates, the concern is water …
