Nutrient-balance assessments are valuable tools for delineating the consequences of farming on soil fertility. Various approaches and methods for different situations have been used. This bulletin presents a state-of-the-art overview of nutrient-balance studies. It brings out the evolution of the approaches and methods, provides for comparisons among them, features the improvements made, and highlights remaining issues. The analysis would be useful in further development of the assessment methodologies as reliable tools for devising time-scale soil fertility management interventions.

Forest and landscape restoration is a key issue in the ongoing discussions at the Paris Climate Change Conference, convened to broker a game-changing agreement on climate change. On a planet where the mark of human activity is almost ubiquitous, restoration is by necessity a concept that has to take into account human well-being and ongoing change. In addition, in order to succeed in the long term, forest and landscape restoration initiatives will need to successfully engage a range of stakeholders, from policy-makers to local communities and from governments to private actors.

Метод картирования ВОКАТ-ЛАДА-ДЕЗИРЕ основывается на исходной анкете картирования ВОКАТ (WOCAT, 2007). Она был расширена чтобы уделить большее внимание таким вопросам как биологическая и водная деградация и придает большее значение непосредственным и социо-экономическим причинам этих феноменов включая их влияния на услуги эко-системы. Она оценивает в форме анкеты какие типы деградации земли в действительности происходят, где и почему и что нужно сделать по этому поводу с точки зрения Сбалансированного ЗемлеУправления (СЗУ).

Une série de 9 cartes s’intéressant aux menaces principales pesant sur les sols ont été préparées dans le cadre de la Journée mondiale sur les sols 2016. Elles offrent une brève description sur l’Imperméabilisation du sol et emprise sur les terres (définition, causes, les principaux faits) et illustre les conditions dans le monde entier et les tendances par région. Les données utilisées pour leur préparation sont tirées des informations publiées dans l'État des ressources du sol le rapport du Monde, publié en Décembre à 2015.

Farmers are constantly being subjected to changes that are beyond their control on account of factors that affect the viability and profitability of their farming enterprises. Therefore in order to sustain agricultural development, farmers must acquire the capacity to respond to these changing situations and opportunities in order to maximize production. Farmers need to be helped to develop this capability by encouraging their innovations and by involving them in a learning process in which they are exposed to new knowledge and technologies.

The front of the postcard provides a short description on Soil organic carbon (SOC) loss (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.
