“…Certains pensent même que du fait qu'ils ne vont pas verser les intrants chimiques directement dans l'eau alors, ce qu'ils utilisent au niveau de leur exploitation ne peut aller polluer l'eau. La source d'eau étant loin d'eux, ils ignorent l'effet de ruissellement pour drainer les résidus dans les eaux de même que la persistance de ces produits dans l'environnement comme l'ont montré Adam et al, (2010), Aïkpo et al, (2015). Les facteurs socio-économiques tels que le sexe, le niveau d'instruction, la taille du ménage et la part de revenu non agricole dans le revenu total influencent positivement le niveau de perception des externalités négatives des pratiques de production de coton.Les résultats obtenus sur le niveau d'instruction sont en lien avec les travaux de N'dambiri et al 2012, Ndamani et Watanabe (2017) de Tatlidil et al, (2009), Abdollahzadeh et al, (2015) selon lesquels il existe une relation positive entre la perception et le niveau d'éducation.…”

“…Diverses études ont montré la dégradation des terres, la contamination des sols, la pollution des eaux, la perte des organismes bénéfiques et donc de la biodiversité (Adam et al, 2010, Agbohessi et al, 2012, Aïkpo et al, 2015, Toko et al, 2014Ba, 2016) dans les zones cotonnières dues à l'utilisation des intrants notamment chimiques. Les engrais chimiques perçus comme source d'amélioration de la fertilité des sols n'ont pas pu combler les attentes puis que le problème est persistant notamment dans le bassin cotonnier (Nacoulma et Guigma, 2015).…”

This study has sought to explore farmers' perceptions of the environmental externalities of cotton production in Benin and the factors influencing the level of perception. Data were collected in northern Benin from 387 randomly selected households (189 organics and 198 conventional). The perception index has been modeled using a Tobit model to analysis the factors that determine perception. The findings reveal that organic producers have a better perception of the environmental externalities of cotton production. Decline in soil fertility is the most perceived negative externality. The factors determining perception are male sex, education level, household size, contact with extension, training on production practices, adoption of organic cotton, experience with the negative effect of pesticides, level of soil degradation and fertility. These results highlight the importance of training and awareness programs regarding good production practices.

“…Already the study conducted in the cotton producing area in 2007 detected the residues of eight pesticides in well water at low volumes (Dem et al, 2007), then the work of Maiga et al, (2014) resulted in quantifications of organochlorine pesticides in well waters to finish with the results of this study which found high levels of organochlorine pesticides with deltamethrin. The autors Aïkpo et al, (2015) concluded that the pesticides widespread presence in all samples at high levels presage of an uncontrolled use of these products. This presence of pesticide residues in the well waters, can be explained by recent use of Deltamethrin in market garden production near wells without coping for most of them.…”

The cotton production in Mali is made with a massive use of fertilizers and pesticides. This use of pesticides against cotton pests raises questions about the level of pollution of the environment in general and the groundwater from the cotton basin of Mali in particular. The study consists of sampling shallow ground water from two areas, each considered vulnerable to ground water contamination from agricultural chemicals. It carried out in the regions of Koulikoro and Sikasso, then consisted of a search for residues of four organochlorine pesticides (DDT, dieldrin, endosulfan α and lindane) and one pyrethrinoid (deltamethrin) in the well water. Five sampling sites (Kassela, Koumantou, Ouelessebougou, Sido and Tienfala) were explored. Two collection seasons were carried out in September 2016 (S1) and September 2017 (S2). They involved a total of 104 well water samples divided into 78 wells without margins and 26 wells with margins. The samples were extracted and analyzed by a gas chromatograph equipped with an Electron Capture Detector. The results show the presence of pesticide residues at measurable concentration for 80 of the 104 wells from the five sites. Pesticides residues were determined in 76.92% of the samples. The pesticide with the highest detection frequency was Deltamethrin which was detected in 20 of the 80 contaminated wells.

“…Among the articles reporting environmental contamination by organochlorine pesticides, we cite the article on the evaluation of pesticide contamination of the waters of the Couffo River in the cotton-growing area of Djidja in Benin (16). The article on Pesticides and the environment in Morocco reports contamination of groundwater, drinking water, soil and plants (17).…”

The inappropriate use of pesticides in the world and particularly in Africa, explains their presence in various environmental compartments. This presence in the environment has harmful consequences on living beings, especially humans. This review, based on scientific publications, aims to analyze the problem of pesticides in Africa. From a corpus of 81 articles published in Africa on this topic between 1996 and 2019, we have outlined the issues relating to phytosanitary practices, environmental pollution, food contamination, intoxication of farmers and consumers, qualitative and quantitative analysis methods used, as well as the regulations on the subject and their application in Africa. Based on an analysis of the factors that are at the root of the problems of environmental pollution, contamination and health that they cause in Africa, possible solutions were proposed to produce healthy products and preserve our common environmental heritage.
