Agência FAPESP – Brazil is recognized as the country with the world’s most efficient biofuel production, which is principally based on sugarcane. The success that the country has enjoyed in transforming this plant into a bioenergy source, however, is due more to a pioneering initiative to create an industrial system for ethanol production than the plant itself.
The system began to be developed in the 1930s when an agronomic development program that made the plant highly efficient was established. Despite these efforts, the agronomic performance of sugarcane is still below that of the other raw materials tested for this purpose over the last few years in different parts of world.

The Fish Site – Per capita income is set to eclipse population growth as the dominant driver of change in the global food system, says a Purdue researcher noted for his work on the economic impacts of global trade and environmental policies.
Thomas Hertel said that while population and income will remain the two most influential factors in determining global food demand and cropland expansion, their relative importance will be altered.
Labex Korea - Achieving both economic growth and better quality of life is human kind’s longstanding aspiration. To that end, we need to tap natural resources in an environmentally sustainable manner and stop polluting environment in the process of consuming the resources.
Advanced nations have made a continuous effort and seen a significant progress in maximizing productivity of resources while realizing economic development that minimizes environmental pollution. They have sought ways to curb environmental degradation by inventing relevant technologies and nurturing industries.
The Ministry of Environmental and Korean Environmental Industry & Technology Institute prepared a book to introduce Korea’s competitive environmental enterprises and technologies to the world.

The Guardian - Ethan Brown likes the taste and texture of meat. He just doesn’t like the morals of it. Until now, that left him with the choice of eating an animal and feeling guilty, or going vegetarian and missing out on the juicy taste of grilled chicken. Fungi-based substitutes such as Quorn don’t tend to cut it with those who miss real meat.
But Brown, a former clean-energy executive, belongs to a new generation of tech entrepreneurs who are taking a new approach to protein. “Look at the impact of meat on the climate”, he says. “Look at its impact on human health, the vast resources meat production consumes and how factory farming affects animal welfare. It’s all pointing in the direction of a major change.” Brown’s solution is making plants taste like poultry. His Los Angeles-based company, Beyond Meat, produces protein that looks, tastes and feels like chicken – but is made entirely from plants.

Science Direct (Summary) – Energy is a vital input for social and economic development. As a result of the generalization of agricultural, industrial and domestic activities the demand for energy has increased remarkably, especially in emergent countries. This has meant rapid grower in the level of greenhouse gas emissions and the increase in fuel prices, which are the main driving forces behind efforts to utilize renewable energy sources more effectively, i.e. energy which comes from natural resources and is also naturally replenished. Despite the obvious advantages of renewable energy, it presents important drawbacks, such as the discontinuity of generation, as most renewable energy resources depend on the climate, which is why their use requires complex design, planning and control optimization methods.

Science Direct (Summary) – Sustainability is a key principle in natural resource management, and it involves operational efficiency, minimisation of environmental impact and socio-economic considerations; all of which are interdependent. It has become increasingly obvious that continued reliance on fossil fuel energy resources is unsustainable, owing to both depleting world reserves and the green house gas emissions associated with their use. Therefore, there are vigorous research initiatives aimed at developing alternative renewable and potentially carbon neutral solid, liquid and gaseous biofuels as alternative energy resources. However, alternate energy resources akin to first generation biofuels derived from terrestrial crops such as sugarcane, sugar beet, maize and rapeseed place an enormous strain on world food markets, contribute to water shortages and precipitate the destruction of the world’s forests. Second generation biofuels derived from lignocellulosic agriculture and forest residues and from non-food crop feedstocks address some of the above problems; however there is concern over competing land use or required land use changes.

The developing-country shares of the projected growth include 81 per cent for meat, 83 per cent for grains and oilseeds, and 95 per cent for cotton. Furthermore, developing countries’ demand for agricultural products is expected to increase faster than their production. As a result, these countries will account for 92 per cent of the total increase in world meat imports, 92 per cent of the increase in total grains and oilseeds imports, and nearly all of the increase in world cotton imports.
Factors behind the rapid increase in developing countries’ demand are high rates of population and income growth, accompanied by increased urbanization and an expanding middle class. Populations in developing countries, in contrast to those in high-income countries, tend to be younger and undergoing more rapid urbanization, which generally leads to more diversified diets. These consumption changes are expected to shift import demand from traditional staples toward feedstuffs and high-value food products.

The Poultry Site – Insects as food and feed are a particularly relevant issue in the 21st century due to the rising cost of animal protein, food and feed insecurity, environmental pressures, population growth and increasing demand for protein among the middle classes, according to a new report from FAO.
FAO has published a book entitled ‘Edible insects: Future prospects for food and feed security’ by Arnold van Huis, Joost Van Itterbeeck, Harmke Klunder, Esther Mertens, Afton Halloran, Giulia Muir and Paul Vantomme of Wageningen University of the Netherlands.
This study is part of a broader research process assessing the local economic, social and environmental impacts from feedstock expansion for the growing biofuel sector. Nonetheless, in the Malaysian context, biofuel production volumes are negligible despite government interest in romoting sector expansion.

Since Malaysia is the second largest palm oil producer in the world, palm oil is slated to become the primary feedstock for biofuel production in the country. Since palm oil consistently outperforms all other substitute vegetable oils on price, it is also becoming an important feedstock globally. While a rapidly growing global biofuel sector could develop into an important new market outlet for Malaysia, it does carry a number of risks. This paper aims to reflect on these risks by exploring the local social and land-use impacts of oil palm in the Beluran District of Sabah State. This is based on household surveys to discover the perception of impacts among relevant local stakeholder groups, and remote-sensing analysis. While the impacts of oil palm in the study site cannot be attributed to the biodiesel industry per se, lessons learnt will be directly applicable to the biodiesel sector in Malaysia, and relevant for the whole Southeast Asia region.

The Guardian – Technology and innovation are powerful tools for change, in both positive and negative ways. As we begin to face up to the multiple economic, environmental and social challenges of our time, could it be that technology offers the solutions at the speed and scale required?
