In view of the continuing increase in cost and scarcity of mineral fertilizers resulting from the use of high-cost fossil energy, there is renewed interest in organic recycling and biological nitrogen-fixation to improve soil fertility and productivity. The workshop in Alexandria recommended the further promotion of research, development, application and dissemination of information available on various aspects of biological nitrogen-fixation, including symbiotic systems of rhizobia/legume and Azolla/blue-green algae, and free-living nitrogen-fixing bacteria and blue-green algae.

Land Tenure Working Paper 11. This co-publication of FAO and UN-HABITAT seeks to better understand and define the processes, mechanisms and institutions of governance of tenure in rural and urban areas. The paper recognises that excellent land policies, laws and technical reforms have been developed. However, in many cases their implementation has slipped, stalled or even been reversed. By adopting a governance and political economy perspective, the paper offers insights for the design of reforms and for the development of land governance tools.

They are important because they can best cater to the specific needs of poor urban households. They also provide employment and income to low income households, and supply food products and services that are tailored to the particular needs of urban consumers.
