The objective of this paper is to examine the feasability of using the walloonian permanent forest inventory to monitor maintenance of the sustainability forest management over time. Criteria and in-dicators which were designed to be used in assessing such a sustainability, as acted in the interna-tional conference of Helsinki, have been analysed to serve at a regional level. The variables selected to define or to be considered as components of indicators have been divided by various types according to 4 classes : “initial” variables (already available in the existing inventory), “calculated” variables (is-sued from data processing or data transformation), “new variables” (addressing parameters less linked to traditional forest inventories), “non relevant” variables (the level and the nature of which cannot be considered in the used sampling method). Slight modifications affecting the design of the inventory and some new observations seem to be sufficient to meet the requirements of a comprehensive monitoring of a sustainable forestry.

This thesis used an integrated approach to develop options for the control of cereal and legumes insect pests in Senegal combining laboratory and field tests. A diagnostic survey was conducted to fully understand current storage practices and control methods in foods and seeds. The study focused on traditional practices from the eastern parts of Senegal to develop options in harmony with the populations concerns. Boscia senegalensis is a plant known for its medicinal properties and its food use was the first plant to be tested for the control of Caryedon serratus, the groundnut weevil. We observed that fruits (3% w/w) and crushed leaves (6% w/w) of this species protected groundnuts. B. senegalensis was subsequently used for protection of cowpea, millet and maize against Callosobruchus maculatus, Tribolium castaneum, Sitophilus zeamais and Prostephanus truncatus. Only T. castaneum was insensitive to this plant at low concentrations. Methylisothiocyanate (MITC) is the main active ingredient of this plant liberated from glucocapparin. This molecule can reach C. maculatus and C. serratus larvae and eggs which develop inside grains but concentrations need to be two to four times higher than adults. Ripe fruits still proved to be effective but immature fruits had a higher efficacy. Residues of MITC were detected in the stored grains after treatment, but the treatment had no effect on germination of stored grains. During the study a reliable and effective method to analyze glucocapparin in leaves and fruits of B. senegalensis was developed, during two years in four localities showing an apparently very marked “soil effect”. Highest glucocapparin concentrations were recorded in January at the beginning of dry season and the lowest during the rainy season from August to November, independent of locality. Powdered maize cobs were effective in maintaining maize grain quality in laboratory studies. Observed damage and losses were respectively 5 and 1% at 2.4% (w/w). At higher doses, mixing of powdered maize cobs with grains offered equal protection as Actellic (pyrimiphos-methyl). The efficacy of this control method was tested during two years in farmer’s granaries confirmed the validity of the laboratory tests. The traditional practice of incorporating insecticidal plants within the storage structure did not impact development of pests already established in the granaries. By contrast, storage of maize cobs using a sandwich method with Hyptis spicigera proved to be effective against storage pests. In addition, the storage of non-winnowed maize grains offered a substantial degree of protection against insect infestations. Their composition was carried out by GC-MS/GC-FID analyses.

Niger faces the brunt of desertification in the Sahelian belt. Many national and international programs attempt to help the country fight against this serious environmental degradation. This article relies on an inter-university targeted program (ITP) funded by the Coopération Universitaire au Développement (CUD) called "Invasion of circular lowlands (cuvettes) of south-eastern Niger by aeolian deposits: processes, impacts and means of struggle" to demonstrate the interest of an inter / multidisciplinary approach in the research of a better solution to an environmental problem as comprehensive as that of desertification. The study is focused on a specific form of desertification, which is that of silting “cuvettes”, areas of lowlands in the south-eastern Niger. Two examples illustrate the practical contribution of this type of approach. The article also shows the link between all the teams who have contributed to the results of the ITP and the development of this special issue. [less ▲]Detailed reference viewed: 74 (6 ULg)
