Results revealed that 8 actives ingredients are regularly used: paraquat, atrazine, glyphosate, chlorpyrifos-éthyl, cypermethrin, maneb, mancozeb and diuron. The contamination of running water and rivers is caused by the fact that 81.25% of them are washing their pulverization equipments in these last ones. Moreover, 72.90% release empty packages of pesticides in the farm which will be carried away by running water. 59.09% adopt the overdose strategy in case of insufficient treatment. The inadequate equipment of protection and the consumption of surrounding water by 51.10% represent a danger for the health of market gardeners. Thus, headache and stomachache are the most recorded intoxications.展开更多

This study is designed to assess the impact of market gardening on soil, water and plant cover in the western Niger Republic. Semi-structured survey data were collected from 78 site operators in the Imanan rural municipality (Filingué, Tillabéry). In addition to the survey, a photographic collection illustrated certain observable facts in the field. The survey shows that the wooden enclosures (70.65% of respondents) around the fields are renewed every year. The impacts are then substantial: deforestation of plateaus, clearing of valleys for new extensions, loss of wildlife habitat, changes in the water flow regime resulting from a geomorphological change in the commune. Itou, the preparation of the planks consumes a lot of water. Thus, the new sinking of water points and the load pressure increase the drawdowns of wells and boreholes in the sites (75.46% of respondents). The frequent spills of waste oil on the sites, as well as the numerous potato storage pits, are among the factors and vectors most likely to contaminate the soils and aquifers of the study area. Market gardening destabilizes the soils and induces regressive erosion as well as area runoff of rainwater on all sites and on the slopes. On the other hand, slash-and-burn practices, drying of branches intended for fences, as well as rain-fed cowpea crops, promote improved physical properties and soil fertilization. To reduce the risks of disintegration and especially of silting up of sites, the study suggests a policy of live hedges and wire fences so that common spaces can be imposed on operators.展开更多

However, it remains one of the potential sources of environmental contamination and public health problems. This study examines the health and environmental risks associated with the use of phytosanitary products in market gardening in the town of Abengourou in Cote d’Ivoire. Field surveys carried out among all (30) market gardener sites housed 150 farmers showed that when the products were spread, no health and safety measures were observed. Approximately 80% of the respondents did not wear gloves or face masks. Some products used were not approved for market gardening. Farmers had itching, dizziness, headaches, colds and vomiting on a regular basis when applying the products. The study also revealed the presence of empty packaging in the surrounding surface water and on the ground. In addition to producers, this type of uncontrolled market gardening likely exposes consumers to high health risks and also contributes to environmental degradation. Raising awareness among stakeholders of good agricultural practices could help promote sustainable market gardening. However, studies of the effects of products in such an environment on the health of consumers deserve to be carried out.展开更多
