Les nouvelles sur l’état de l’agriculture en Afrique sont en grande partie décourageantes, mais on entrevoit des lueurs d'espoir. Quelques efforts stimulants réalisés par des agriculteurs et chercheurs africains au cours des dix dernières années ont sensiblement augmenté la productivité agricole dans certains pays et pour certains produits. Ces cas peuvent servir de modèles pour de futurs efforts, mais seulement si les responsables des politiques de développement et les professionnels comprennent les processus qui ont amené ces résultats, et les éléments clé de leur succès.

The current study attempts to examine whether large-scale agricultural investment of this type benefits the poor and how this investment can be implemented to increase benefits for the poor. It is arguable whether the poor need more land to grow crops to meet their food security requirements or need to benefit from large-scale agricultural investment in Cambodia. Although the poor households are capable of operating small plots of a few hectares each, they generally lack capital and the means to work large chunks of new land with forests or degrade forests.

FIRST PARAGRAPH OF OVERVIEW: This paper is part of a study “Policy Analysis for the Development of Land Policy for Socio- Economic Development.” Land policy relates to the institutional arrangements through which the Government of Vietnam defines which individuals and groups have access to rights in land and the circumstances that apply to gaining and retaining that access.

ABSTRACTED FROM THE INTRODUCTION: This is a study of the rice economy in Myanmar. It seeks to identify barriers and bottlenecks that are hindering growth and depressing value in a sector that must play a central role in alleviating the extreme poverty that currently afflicts an expanding proportion of rural households.

INTRODUCTION: Over the last 30 years, the context of development in Cambodian has undergone dramatic changes. A succession of deep transformations, characterized by a complete restructuring of institutional and socio-economic environment, has resulted in a singular situation. Cambodian society remains largely agrarian, with land being the corner stone of the production system for a large majority of the population.

Los últimos episodios de volatilidad extrema de los precios en los mercados agrícolas mundiales presagian mayores y más frecuentes amenazas a la seguridad alimentaria mundial. Para reducir la vulnerabilidad de los países, las políticas deberían equiparlos para que puedan hacer frente a los efectos adversos de una volatilidad extrema, y mejorar el funcionamiento del mercado.

Agri-environment schemes (AES) are central to the conservation of Europe's farmland biodiversity. The UK Government's Public Service Agreement target seeks to reverse the decline of farmland birds in England by 2020 through the use of AES. The Entry Level Stewardship (ELS) scheme, introduced in 2005, is the first non-competitive, broad-uptake stewardship scheme designed to deliver simple but effective environmental management on farms throughout England.

The aim of this paper is to set-up the algorithm for determining the degree of workabilityof the soil, to help the owners of family farms to plan working hours of agricultural machines, i.e.with the machine park management. The plans, which would be made by use of these algorithmsand based on the accurate information of the cultivation conditions, would result in the appropriateuse of time and capacity of the agricultural machines. In some sectors, such as agriculture or certainindustries, chance that certain event occurs plays a very important role.

The development of synergies between efforts to mitigate land degradation and biological diversity decline can enhance effectiveness, speed up implementation and avoid potential conflicts. Due to the variable nature of these processes and to the variable characteristics of the areas where they occur, there is no general rule linking land degradation and biological diversity decline. Thus, a geographically limited approach focusing on drivers of change may provide a more appropriate base upon which synergies can be built. This exercise is undertaken for the case of northern Mediterranean.

In the vicinity of a city, farmers are confronted with increasing agricultural land prices and rents along the rural-urban gradient, but they concurrently enjoy the advantages associated with proximityto a larger and wealthier consumer base. We hypothesize that farmers transition fromlow-value, land-intensive \traditional" crops to high-value, labor-intensive \specialized" crops on parcels located closer to urban centers. Once returns to development of a parcel exceed theprofits associated with farming, exurban farmers may sell their land for conversion to urban use.

The impacts of agricultural practices and landscape composition on bee communities were investigated in 14 sites located in four Western European countries (Belgium, France, the Netherlands and Switzerland). Standardized interviews with farmers assessed agricultural practices in terms of agricultural inputs (nitrogen fertilization and pesticides), livestock density and crop types. The proportion of semi-natural habitats was calculated for each site. We showed negative effects of agricultural intensification on species richness, abundance and diversity of wild bees.
