This bulletin gives an overview of the ninth session of the working party on Soil Classification and Survey of the European Commission on Agriculture that took place in Ghent, Belgium, in september 1973. It presents the papers, discussions and recommendations developed during the meeting. A methodology of land evaluation is being developed in FAO and will be used for the interpretation of the FAO/UNESCO Soil Map of the World with a view to making a global evaluation of the land resources available for agricultural development.

Extensive grazing is the predominant form of land use on at least a quarter of the world’s land surface, in which livestock are raised on food that comes mainly from rangelands. Extensive grazing differs from crop or forestry production, in which the produce remains in situ whilst growing. Evaluation for extensive grazing, unlike that for cropping or forestry, must take into account the production of both grazing forage, termed primary production, and the livestock that feed on this forage, termed secondary production.

This issue of Unasylva analyses the urban forestry situation and considers its potential for increasing living standards in different urban settings.

High-precision land-cover-land-use GIS mapping was performed in four major townships in Maine’s Aroostook River Valley, using on-screen digitization and direct interpretation of very high spatial resolution satellite multispectral imagery (15–60 cm) and high spatial resolution LiDAR data (2 m) and the field mapping method. The project not only provides the first-ever high-precision land-use maps for northern Maine, but it also yields accurate hectarage estimates of different land-use types, in particular grassland, defined as fallow land, pasture, and hay field.

Kenya is going through a period of intense transition. The country's main development policy, Vision 2030, is just entering the second Medium Term Plan of Implementation from 2013. The development priorities focus extensively on large scale investments, for industrial, irrigated agriculture, utilization of newly discovered natural resources, and infrastructure development. Land is therefore a central commodity for realization of the sought after socioeconomic transformation.
