Aviation makes a massive global, socio-economic contribution (Oxford Economics 2011). Growth is generally fastest in developing countries, precisely because it’s so intimately linked to economic development. At the same time, it's clear aviation is carbon-intensive and in need of low carbon solutions. It’s a huge challenge, and huge opportunity to make a big difference. Any breakthroughs could not only change aviation, but also the wider transport industry, with its big carbon footprint (2% global carbon contribution for aviation, and growing; 4% for shipping; 12% for other transport: WRI, 2005). Our biggest opportunity to make a significant difference is by supporting next-generation, low carbon fuels, while avoiding the problems of earlier generation ‘biofuels’, by using novel feedstocks like waste gases, liquids and solids. (How amazing to make a fuel from ‘recycled’ carbon that would otherwise end up in our atmosphere, rather than taking new carbon out of the ground?) We insist on suppliers using the RSB gold-standard, international, independent, multi-stakeholder standard for sustainable fuels, which includes robust LCA methodology. We encourage the technological know-how. But much supplier work is early-stage, and there’s a big funding gap that airlines alone cannot address. We at Virgin are accelerating the fuels’ route to commercialisation by convening key leading stakeholders (inc. suppliers, NGOs, scientists, policy-makers, industry, and – crucially – financers) to create a market and solutions. Much of the detail is confidential, but this is the essence of it.

Ceiba maximizes project returns by matching feedstocks with appropriate bioenergy technologies in developing economies with high energy consumption metrics, making smaller scale bioenergy an accessible enterprise. The bioenergy value chain begins with energy agriculture and tropical agroforestry systems which provide the feedstocks for bioenergy projects with technologies such as gasification and pyrolysis. Ceiba’s energy agriculture team grows and manages fast-growing oil crops, biomass crops and timbers to provide a continuous feedstock supply -- often in conjunction with other existing agriculture or forestry waste -- increasing project reliability and viability. Our agronomists and foresters plan and implement strategies with fast-growing oil and biomass crops, bamboo and precious hardwoods for oil, timber and biomass production. We hire local community members in all aspects of our operations, and offer employees the opportunity for training and upward mobility within the company. These strategies underpin bioenergy project stability, maximize land productivity and asset value with multiple timescale revenue streams. Ceiba monetizes this value, with a team well-versed in feedstock contract negotiation, PPA acquisition, project finance, as well as corporate structuring -- assuring successful implementation. We help to green and stabilize the grid, reducing transmission and transport losses of energy. Our production systems support more biodiversity than competing uses (eg cattle), and can boost local production of new crops, increasing agroecosystem diversity.

The first action we implemented thanks to the community responds to both the environmental and social goals of our CSR strategy.

I started a new topic online asking “How can we make sure that the waste we recycle in our offices are actually dropped in the correct public cans at the end of the day?”

People teamed up and came up with a new initiative: to recruit persons with Down syndrome to take charge of our waste management. They will first act on reducing and reusing resources (eg. create notepad with used paper). Then, they will recycle the trash in the correct public cans. This solution enable us to go even further and organize regular collect of goods from the employees for local NGOs such as clothes, toys, medicine drugs, hygiene products, food, etc.

The team has now contacted an agency helping disabled people to recruit 3 new part-time employees. 3 persons are going to be able to work. Even though it will be few hours a day, I know it means a lot to them, having their first job…

This community has the power to do good, for the company, for our employees who see direct results of their actions and for the society.

Nearly 70 percent of people in the African continent do not have access to the national power grid, and the 30 percent who do have access cannot rely on steady power. While the government develops and extends the national grid, they also have increasingly sought alternative energy sources-such as the Bishop Kodji solar project-to meet the shortfall but the major problem is maintainability .
Example : Five years ago, the Lagos state government in Nigeria launched a solar electrification project at the Onisowo village of Bishop Kodji. The first of its kind in the state. The project was built to power water pumps, fish driers, and street lamps, giving the tiny fishing and boat-carving community's 5,000 residents easier access to drinking water, securing their sandy streets, and strengthening the oceanic island's fishing economy.Things didn't go as planned.
"We don't know what's going on," said Azime Anthony. "It only worked for about three months, then it stopped. All the places where we are supposed to have light are dark and they never came back to try to fix any of it."
This is just the main problem in service delivery in Africa but having been in the UK for over 11 years and see how things are meant to be done, the package we have will surprise everybody.
We will set up and manage these solar farms in different locations to power the areas. We will install and own the system, have a power purchase agreement with the users which will include monthly service charges. With this, maintenance will be our number one priority and we believe that will be the difference.

Kitchen gardening: The purpose of use this term is that farmers can produce or grow vegetations in their home garden, which don’t have enough land. These practices are very useful for daily necessary things for a home like Pepper, onion and cucumber. Temperature: When we are making nursery in plastic nursery the temperature should be minimum 18˚c and maximum 24˚c. The change in temperature may effect / damage vegetables. The access of moisture in tunnel also affects the vegetables. To protect vegetables from disease should to protect its leaves as leaves get disease the vegetable damage badly. We can get 1440 cucumber plants from 5 kg seed and get 0.4 million from one acre land.

Tunnel Farming: Tunnel farming is the method by which we can control moisture and cold. We also can grow off season vegetables. Wire hoops with perforated shopper over it and plants nursery is in under these hoops. By closing the shopper ends we can maintain the temperature of the tunnel at which vegetable growing speed increases. We also give require temperature by locally made tunnels.

Urban food gardening requires suitable land, labour, and skill.
It is a rare person in the "developed world" of the 21st century who has simultaneous claim to all three. By connecting skilled practitioners of SPIN (Small Plot INtensive) food gardening with eager landowners and their landless neighbours, Village Vancouver has dramatically increased urban agricultural production. This enables a low or no-carbon source of fresh, nutritious, and waste-free vegetable and fruit produce and simultaneously teaches urban populations about organic food production, sustainable farming, and the value of sharing land, skills, and labour for mutual benefit.
Aside from multiple informal and formal "yard-swaps" paired with agricultural training, Village Vancouver has championed "urban collaborative market gardening," a new model for food production in cities. In contrast with community gardening, where individuals tend to small plots, this collaborative model pools such plots into far larger row or field production to take advantage of economies of scale, skill-sharing, labour-sharing, and organisational learning. Labour is rewarded with a share of the harvest, and any excess is sold or distributed in the neighbourhood to extend the community benefit of locally-produced food.
These are the modern day Victory Gardens that will help us win the war on climate change and the worst excesses of industrial agriculture.
