“…varying between 0.06 ± 00 and 1.35 ± 0.2 mg/L in certain rivers in the country in the dry season. In the rainy season the same authors reported values ranging from 0.04 ± 0.0 to.55 ± 0.0 mg/L[7] found 4 NH + values between 0.01 and 0.29 mg/L with an average of 0.29 ± 0.83 mg/L and 0.011 and 0.4354 mg/L with an average of 0.407 ± 1.28 mg/L in the Moulouya and Ansegmir wad is in Morocco. Ammonium ions are the reduced form of nitrogen pollution.…”

The present study focused on the chemical characterization of the watercourse of the Togbadji Lake wildlife ranch. The methodological approach followed is as follows: Bibliography review, Sampling campaign. The results obtained were the subject of descriptive statistics, the two-sample Wilcoxon test to determine the impact of different localities on the abundance of microbiological contaminants, a Principal Component Analysis (PCA) with the software R version 3.5.0, in order to group the pollution parameters according to the different levels and sources of contamination. From our results, it is found that the respective average values in dry and rainy seasons for ammonium ions are 0.38 ± 0.16 mg/L and 0.22 ± 0.03 mg/L; for nitrite ions 0.20 ± 0.25 mg/L and 0.02 ± 0.01 mg/L; for nitrate ions 3.72 ± 2.52 mg/L and 7.84 ± 4.91 mg/L; for total Kjeldahl nitrogen 1.27 ± 1.44 mg/L and 1.19 ± 1.49 mg/L; for orthophosphate ions 0.20 ± 0.25 mg/L and 0.02 ± 0.01 mg/L; for total phosphorus 0.04 ± 0.01 mg/L and 0.11 ± 0.23 mg/L; the chemical oxygen demand 93.36 ± 61.73 mg/L of O 2 and 89.93 ± 66.11 mg/L of O 2 and the biochemical oxygen demand over 5 days 25.50 ± 18.22 mg/L of O 2 and 37 ± 33.15 of O 2 . It emerged that the main sources of pollution in Lake Togbadji are runoff water, discharges of various wastewater from artisanal activities, livestock farming and open defecation.

The 2016-2017 agricultural season was devoted to prospecting in different farms in the Triffa Plain. Mildew is present in almost all areas of the plain, given the favourable climatic conditions. Around 95% of the potato cultivated areas in the irrigated area of Moulouya are concentrated only in the Triffa plain, from which 51 plots have been identified. This survey showed that a total of 34 plots (476 hectares covering about 22% of the total area under potato cultivation) were attacked differently by the late blight, and the area managed by the Agricultural Valorization Center (AVC 108) showed the highest attack degree .Preventive control is the most used measure by farmers to protect their crops from attacks by this pathogenic fungus. More than 89% of farmers apply chemicals with health protection measures that are often insufficient or totally absent (77% of farmers apply 4 to 6 fungal treatments per cycle). However, the non-rational use of these chemicals revealed serious problems that are harmful to the various environment components, namely fauna and especially human beings’ health. The results obtained in this study recommend the use of rather organic and ecological treatments that are favourable for the preservation of human health and guarantee a sustainable and healthy agricultural production.
