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.

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).

This guidelines booklet is addressed to the LADA partner countries and, more in general, to the increasing number of countries which are expressing their interest in implementing the LADA approach for mapping Land Degradation. The specific objective is to provide guidelines for the identification, selection and description of nationally based indicators of land degradation. The LADA approach is well defined by a range of specific documents and manuals. The National indicators common to all countries are based on the LADA-Wocat QM manual.

Agricultural productivity in Zimbabwe, like in many other countries in SSA has been declining over the years despite the numerous advancements made in agricultural technology development. Yield levels usually averaging below 1t ha-1 have resulted in persistent cereal deficits despite the large area put under production each year.

Attainment of MDG-7 (environmental sustainability) requires the realization of sustainable agriculture systems. There is now inexorable pressure on world agriculture to play a much wider range of roles than ever before.
