Synopsis (short abstract) The possible competition for land makes it impossible to produce enough first generation biofuel to offset a large percentage of the total fuel consumption for transportation. As opposed to land-based biofuels produced from agricultural feedstocks, cultivation of algae for biofuel does not necessarily use agricultural land and requires only negligible amounts of freshwater, and therefore competes less with agriculture than first generation biofuels. Combined with the promise of high productivi ty, direct combustion gas utilization, potential wastewater treatment, year-round production, the biochemical pathways and cellular composition of algae can be influenced by changing cultivation conditions and therefore tailored on local needs. On the other hand, microalgae, as opposed to most plants, lack heavy supporting structures and anchorage organs which pose some technical limitations to their harvesting. The reasons for investigating algae as a biofuel feedstock are strong but thes e reasons also apply to other products that can be produced from algae. There are many products in the agricultural, chemical or food industry that could be produced using more sustainable inputs and which can be produced locally with a lower impact on naturalresources. Co-producing some of these products together with biofuels, can make the process economically viable, less dependent from imports and fossil fuels, locally self sufficient and expected to generate new jobs, with a positive ef fect on the overall sustainability. This document provides an overview of practical options available for co-production from algae and their viability and suitability for developing countries.

    "This paper provides an overview of the main risks and opportunities that may arise from liquid biofuel production and use in developing countries. Both the potential environmental impacts and the socio-economic effects of liquid biofuel production and use are discussed, focusing, in particular, on the household-level implications. A few country-levels impacts, which might trickle down to the household level, are discussed as well. Recommendations on how to minimize the risks and maximize the opportunities of liquid biofuel production and use are provided in the final section of the paper".

    The livestock sector is transforming rapidly in response to shifts in the global economy and changing societal expectations. Society expects the livestock sector to provide safe and plentiful food and fibre for growing urban populations, livelihoods for more than a billion poor producers and traders as well as global public goods related to food security, environmental sustainability and animal-borne diseases. However, the rapid pace of change has led to unbalanced growth of the sector. This has manifested itself in a widening dichotomy within the sector in terms of the scale, intensity and efficiency of production and in unforeseen social, nutritional, animal health and environmental implications. These changes and the speed with which they are occurring have created systemic risks for livelihoods, human and animal health and the environment. To meet the challenges and constraints of the twenty-first century, the livestock sector requires appropriate in stitutions, research, development interventions and governance that reflect the diversity within the sector and the multiple demands placed upon it.

    Women in Agriculture: closing the gender gap for development

    Women make significant contributions to the rural economy in all developing country regions. Their roles OF FOOD AND AGRICULTURE differ across regions, yet they consistently have less access than men to the resources and opportunities they need to be more productive. Increasing women’s access to land, livestock, education, financial services, extension, technology and rural employment would boost their productivity and generate gains in terms of agricultural production, foo d security, economic growth and social welfare. Closing the gender gap in agricultural inputs alone could lift 100–- 150 million people out of hunger. No blueprint exists for closing the gender gap, but some basic principles are universal: governments, the international community and civil society should work together to eliminate discrimination under the law, to promote equal access to resources and opportunities, to ensure that agricultural policies and programmes are gender-aw are, and to make women’s voices heard as equal partners for sustainable development. Achieving gender equality and empowering women in agriculture is not only the right thing to do. It is also crucial for agricultural development and food security.
