    Desde 1988 el sector ejidatario mexicano se ha visto afectado
    por una serie de cambios de política y perturbaciones exógenas
    que han puesto en tela de juicio la viabilidad agrícola del
    sector en su conjunto. Los cambios --liberalización del comercio,
    privatización, reducción de los subsidios, eliminación
    de los controles de precios, perturbaciones macroeconómicas,
    devaluación y grandes reformas del marco legal que rige el
    uso de la tierra en los ejidos-- han llevado a un reordenamiento

    Since 1988 the ejido sector in Mexico has been buffeted by a series of policy changes and exogenous shocks that have brought into question the agricultural viability of the sector as a whole. These changes -trade liberalization, privatization, falling subsidies, the abolition of price controls, macroeconomic shocks, devaluation and momentous changes in the legal framework governing land use in the ejido- have led to a radical reordering of the policy framework and incentive structure under which the farmers of these communal lands operate.

    Kenya

    The various legal, political, economic and social perspectives that have influenced the land reform discourse in Kenya are examined. The historical perspectives of the land question in Kenya are outlined, and the factors that shaped the content of Kenya's land law and attendant institutional and constitutional regimes are addressed. The operationalization of the legal regimes and policy frameworks emergent from the colonial legacy is also extensively dealt with, focusing on the way the state has sought to balance private and public interests in land through the instruments of law.

    The importance of cassava relative to other crops in the cropping system was almost total; cassava was present in 70% of arable fields; maize and beans or peas were each present in 13% of arable fields and all other crops were present in 4%. Cassava was produced mostly for sale, yet it was not as important around market centers as in remote areas because imported rice and wheat products were easily accessible.

    Since 1995, experiences have been gathered with the calculation of National Greenhouse Gas Inventories in Germany. Because only marginal changes of the total forested area occur in Germany, relevant changes of the balance of greenhouse gases in the forest sector are related to forest management. It was found that the increment of wood by far exceeds the harvested timber volume. Therefore, forests in Germany currently represent a significant sink for carbon (8-9 Mt C per year).

    Identifying the appropriate germplasm to be improved is a key component of any participatory breeding effort because of its implications for impacts on social welfare and genetic diversity. This paper describes a method developed to select a subset of 17 populations for a participatory breeding project from a set of 152 maize landraces. The larger set of landraces was collected in order to characterize, for conservation purposes, the maize diversity present in the Central Valleys of Oaxaca, Mexico.
