La herramienta Garantía de calidad - control de calidad (GC-CC) y verificación es parte de las Herramientas de análisis de emisiones del sector AFOLU, destinadas a apoyar a los países miembros a países miembro para mejorar la capacidad nacional de satisfacer los requisitos de presentación de informes de la Convención Marco de las Naciones Unidas sobre Cambio Climático (CMNUCC), y para diseñar acciones de política climática (i.e.

健康的土壤是满足粮食、生物质（能源）、纤维、饲料等产品不同需要的基本前提， 并确保在世界所有区域提供必要的生态系统服务。然而，人类正面临着前所未有的土 壤资源压力。特别是，各种类型的土地退化，包括快速城市化造成的土壤板结正在招 致沉重的代价，威胁着粮食安全和生态平衡。考虑到目前处于审议阶段并很快付诸实 施的可持续发展目标，必须从根本上保证土壤的可持续管理，才能让这些目标变为现 实

The present report gives the complete description of the preparation of a land use map and also the preparation of a national map of livestock intensity, needed as LUS input. The present method allows the preparation of a multi-country land use map in two weeks with the work of 13 experts, and is comparable to the continuous of 130 working days. Further to that, the LUS has been validated with the support of GIS consultants.

Здоровье почв является одним из главных условий, необходимых для удовлетворения разнообразных потребностей в продовольствии, биомассе (энергии), волокнах, кормах и других видах продукции, а также для обеспечения основных экосистемных услуг во всех регионах мира. Вместе с тем человечество сталкивается с беспрецедентным давлением на почвенные ресурсы. В частности, различные виды деградации почв, в том числе их запечатывание, которое связано с быстрой урбанизацией, наносят тяжелый урон, угрожая продовольственной безопасности и экологическому равновесию.

La tercera edición de la WRB incorpora, en el nuevo capítulo 2, elementos que permiten generar nombres taxonómicos mucho más informativos que llevan a deducir con facilidad la génesis y funciones de los suelos. Por otro lado, esta nueva versión de la WRB facilita la elaboración de leyendas de mapas a varias escalas para uso multifinalitario.

Des sols sains sont une condition préalable essentielle pour satisfaire divers besoins en nourriture, biomasse (énergie), fibre, fourrage et autres produits; et pour assurer la fourniture de services écosystémiques essentiels dans toutes les régions du monde. Cependant, les ressources en sol de l’humanité sont confrontées à des pressions sans précédent. Il s’agit notamment de diverses formes de dégradation des sols, dont l’imperméabilisation liée à une urbanisation rapide, qui ont de graves conséquences. La sécurité alimentaire et l’équilibre écologique de la planète sont menacés.

The completion of this comprehensive harmonized soil information database will improve estimation of current and future land potential productivity, help identify land and water limitations, and enhance assessing risks of land degradation, particularly soil erosion. The HWSD contributes sound scientific knowledge for planning sustainable expansion of agricultural production and for guiding policies to address emerging land competition issues concerning food production, bio-energy demand and threats to biodiversity.

The future is increasingly urban and inevitably so. Urbanisation is increasing at unprecedented rate in both Sub-Saharan Africa and developing world (UN Habitat, 1999). Alongside this rapid expansion comes the emergence of the peri-urban areas that are characterised of increasing intensification and co-existence of urban and rural areas, marked by dynamic flows of commodities, capital, natural resources, people and environmental pollution.

The history of surveys and mapping in Tanzania has been influenced by two European cultures through its colonization; first by the German and then by the British. During the German Administration, surveys and mapping activities were carried out by the Department of Surveys and Agriculture from 1893 to 1914. When the British took over the mandate for the territory after World War I, the also used the “old” German maps until when they when they started the surveys to produce other topographic maps from 1946. In 1961, the Surveys and Mapping Division was created.
