The present study describes a methodology to quantify the gross soil nitrogen balance (SNB) for agricultural land use in the Tagus Nitrate Vulnerable Zone (TVZ) between 1989 and 2016, including effects of implementation of the EC Nitrates Directive (ND, 91/676/EEC) since 2004. The study uses decadal information from National Agricultural Census at parish level and is supported by a Geographical Information System (GIS). The average SNB of the TVZ decreased significantly (p 

O tema do mercado de terras integra a agenda contemporânea das políticas agrárias, tanto no Brasil como em outros países. No caso brasileiro, decorre da história de ocupação do território e da própria formação social e econômica que produziram um quadro de ilegalidade, de instabilidade jurídica e de fragilidade institucional.

A história da agricultura mundial no último meio século tem sido, sobretudo, a história de transformações produtivas, impulsionadas pela ciência e pela intensificação tecnológica, e a resultante expansão da capacidade produtiva, pari passu com o crescimento da demanda de alimentos.

Cette journée de réflexion a été consacrée à la place de l’enjeu foncier en milieu rural dans les conflits civils contemporains dans les pays en développement. Elle a mobilisé le réseau élargi du Comité, avec plus d’une cinquantaine d’experts, de chercheurs et de décideurs venus contribuer au débat. Jean-Pierre Chauveau et Éric Léonard de l’IRD-Pôle foncier de Montpellier ont assuré le cadrage général et l’identification des principaux intervenants.[…]

Dans un contexte de pression accrue sur les terres et les ressources naturelles, la formalisation (reconnaissance légale et écrite) des droits fonciers est aujourd’hui présentée comme un moyen à privilégier pour une meilleure sécurisation foncière.

L’élevage pastoral et agropastoral (ou pastoralisme) est un système de production basé sur un élevage extensif valorisant majoritairement les parcours naturels. Utilisé par des communautés qui vivent dans des contextes souvent marginaux, il est associé à un mode de vie fondé sur un lien particulier entre l’homme, l’animal et la nature.

En 1962, René Dumont publiait L’ Afrique noire est mal partie. Ce livre, qui concernait essentiellement l’Afrique de l’Ouest, fit scandale à l’époque car il intervenait au lendemain des indépendances des colonies européennes, à un moment où les jeunes États africains pouvaient espérer un développement prometteur.

This paper examines the intersections between youth access to land, migration decisions and employment opportunities using nationally representative and multi-year data from multiple African countries. We document evidence on the evolving dynamics in land distribution and ownership patterns, the effect of land access on youth livelihood choices and development of rental and sales market in the region.

A narrative on rural youth in Africa has continued to evolve in policy circles around the world. Much of it is driven by population statistics that point to an imminent youth bulge in Africa and concerns about a poor economic outlook (stagnation) for African productivity and growth. Fears of massive unemployment, social unrest and undesirable migration due to limited economic growth drive the bulk of the discourse. This is juxtaposed with the promise of a youth dividend for the continent, which is highlighted by some quarters of the policy debate.

Countries of the Near East, North Africa, Europe and Central Asia (NEN) region face a myriad of social, economic and political challenges that have stalled their structural and rural transformation processes. This has had a detrimental impacton rural youth, who, as a result, face limited economic opportunities. The NEN region has the highest youth unemployment rates in the world. Weak education systems are failing to provide youth, especially in rural areas, with the cognitive and non-cognitive skills they need to compete in a global economy.
