Drainage of agricultural land is one of the most critical water management tools for the sustainability of productive cropping systems, as frequently this sustainability is extremely dependent on the control of waterlogging and soil salinization in the rootzone of most crops. On some agricultural lands, the natural drainage is sufficient to maintain high productivity. However, many others require improvements in surface and subsurface drainage in order to optimize land productivity, while maintaining the quality of soil resources.

The share of agriculture in the GDP declined from 16 percent in the 1990s to almost 14 percent in 2010. Meanwhile, those employed in agriculture as a percent of total labor force is declining since 1960 to 2006. Despite losing labor and share of the GDP, agriculture is, and will continue to be, among the major economic activities in Egypt, and a generator for economic growth. The balance between agriculture and other productive sectors of the economy require proper spatial and land use planning. Land tenure is central to this planning exercise.

This thirty-page report is the third out of three reports written on forest resources in Madagascar. It is aimed at the collection, analysis of data related to the forest plantations sector in Madagascar. Different from the other two reports, it deals with issues related to village plantations and its uses by local families. The report is composed of six main topics dealing with the methodologies used, the surface of the plantations, total volume of these, the commercial aspects, the duration of rotation and the dynamics of reforestation and exploitation.

The front of the postcard provides a short description on Soil contamination(definition, cause, key facts) while the back gives the worldwide conditions and trends by region. The data given here is derived from information published in the Status of the World's Soil Resources report, released in December 2015.

The Report and the Technical Summary are available at the links below:

One of the greatest challenges faced by mankind is to satisfy the needs of the fast growing global population and at the same time preserve land, water, air and biodiversity resources. Livestock are a crucial element in this balancing process. Demand for livestock products is growing fast, especially in the developing world. Livestock, through their multiple functions, are a cornerstone of the livelihood of most of the rural population in the developing world.

Agriculture must, literally, return to its roots by rediscovering the importance of healthy soil, drawing on natural sources of plant nutrition, and using mineral fertilizer wisely.

La mayor parte de los nmeros de Unasylva se centran en un tema concreto. El objetivo de esa orientacin temtica es examinar de forma pormenorizada un aspecto determinado de las actividades y el desarrollo forestales, con el fin de resaltar su significado e importancia dentro de los confines ms amplios de nuestro universo. Sin pretender que los diferentes nmeros sean como un manual de una materia concreta, se propone presentar una serie de anlisis de cuestiones especficas que contribuyan a suscitar inters y a concienciar al lector.
