Analyse socio-economique des effets des interventions de la fao sur le renforcement de la resilience des menages vulnerables dans la commune de kalfou, region de tahoua au niger

Abstract: In accordance with its vision of development, the Food and Agriculture Organization of the United Nations (FAO) took action in Niger in the Tahoua region through the implementation of four types of interventions. These include the distribution of unconditional cash (Action 1), the distribution of agricultural inputs and technical training (Action 2), unconditional cash followed by distribution of agricultural inputs and technical training (Action 3), through the combination of Action 3 followed by distribution of zootechnical inputs (Action 4). This study was carried out to analyze the effects of these interventions on improving the living standards of vulnerable populations. Also, a household survey was carried out with 10% of the beneficiaries of the villages of the commune of Kalfou, region of Tahoua. A total of 40 heads of households were surveyed. The results showed that Action 1 enabled 30% of the beneficiaries to set up working capital to carry out an activity that generates income. Improved food availability is observed in 100% of beneficiaries with Action 2. Actions 3 and 4 have enabled 40% and 70% of beneficiaries respectively to increase their income. The results of the study will enable decision-makers to choose the options for strengthening the resilience of the most vulnerable households.

Caractéristiques Physico-Chimiques Des Eaux De La Nappe Alluviale De La Vallée Du Goulbi N'Kaba Dans La Région De Maradi Au Niger

Abstract: The Goulbi N'Kaba valley is located in the Maradi region of southcentral Niger. It contains an alluvial aquifer that is used for the drinking water supply, breeding, increasingly more irrigation and for the extractive industries. In addition, this valley is subject to the effects of climate change. A study is needed to improve the knowledge of this water resource, a condition for a better match between the uses and the potentialities of the aquifer. The investigations on the physicochemical parameters and the stable isotopes of the water molecule (oxygen 18 and deuterium), made it possible to reach the following main results: The waters of the alluvial aquifer are slightly acidic, with a pH ranging from 5,2 to 7.2. The mineralization is relatively weak with conductivities between 89,3 and 325 μs/cm, resulting in sodium and calcium bicarbonate facies. These waters are generally good for human consumption and for irrigation. However, in the center of the study area, fluorine and nitrate contents are observed that exceed the WHO guideline values (2006).

Morbi-Mortalité des Contusions Abdominales : La Face Visible de L’iceberg

Abstract: Objectif : rapporter la morbimortalite des contusions abdominales (CA) a l’hopital national de Niamey. Patients et methode : il s’agissait d’une etude retrospective, descriptive et analytique sur 4 ans incluant les patients pris en charge pour CA a l’hopital national de Niamey. Les variables etudiees etaient le sexe, l’âge, le mode de traitement, les lesions abdominales, les lesions associees, la morbidite et la mortalite. Resultats : l’etude incluait 137 patients, soit 1,6% des urgences abdominales. Il s’agissait de 116 hommes et de 27 femmes avec un sex ratio de 5,52. L’âge moyen des patients etait de 22,09 ±12,3 ans. Le delai moyen d’admission etait de 18,4 ±26,3 heures. Les accidents de la voie publique representaient 49,64% des circonstances de survenue du traumatisme. La CA etait isolee chez 75,2% des patients et associee a une lesion extra-abdominale chez 24,8% des patients. Cette association lesionnelle realisait un polytraumatisme chez 18,9% des patients. Les lesions abdominales etaient dominees par les lesions spleniques survenues chez 38,6% des patients, suivies par les lesions de l’intestin grele chez 12,4% des patients. Une complication etait survenue chez 10,9% des patients et 6,5% des patients etaient decedes a l’hopital. La survenue de complications etait influencee par le delai d’admission et la survenue d’une peritonite (p=0,002). L’hemorragie etait la principale cause de deces. Conclusion : les CA constituent un traumatisme de l’adulte jeune de sexe masculin. La morbimortalite des CA n’est peut etre que ‘’la face visible de l’iceberg’’. Objective : to report the morbidity and the mortality of the blunt abdominal trauma (BAT) at the national hospital of Niamey. Patients and method: it was a retrospective, descriptive and analytical study over 4 years including patients managed for BAT at the national hospital of Niamey. The variables analyzed were the age, sex, treatment, abdominal organs injury, associated injury, morbidity and mortality. Results: the study included 137 patients, whether 1.6% of abdominal emergencies. They were 116 men and 27 women, with a sex ratio of 5.52. The average age was 22.09[±12.3] years old. The average intake time was 18.43[±26.3] hours. Car crashes accounted for 49.64% of the circumstances of the trauma. The BAT was isolated in 75.2% of patients and associated to a (34) extra-abdominal trauma in 24.8% of patients. This lesional association achieved polytrauma in 18.9% of patients. The most abdominal organ injured was spleen in 38.6% of patients followed by small intestine in 12.4% of patients. The morbidity rate was 10.9% and the intrahospital mortality rate was 6.5%. The occurrence of morbidity was influenced by the intake time and the occurrence of peritonitis (p=0.002). Hemorrhage was the leading cause of death. Conclusion: BAT are most frequent in young male adults at national hospital of Niamey. The morbimortality of BAT is perhaps ‘’the visible face of the iceberg’’.

Physicochemical analysis of crude waste waters from industrial and domestic sources in the Kossodo market garden site (Ouagadougou)

Abstract: In Burkina Faso, Water resources are threatened today by pollution from domestic waste, industrial and agricultural discharges without adequate treatment. This pollution is the main cause of degradation of water quality. The objective of this study is to evaluate the physicochemical quality of the water in the market garden site of Kossodo watered with sewage sludge from the city of Ouagadougou industries. Indeed, seven (7) wastewater samples collected over a 90 days period at the site where a Water Treatment Plant (WTP) was installed were analysed in the laboratory. The parameters were pH, EC, Ca2+, Mg2+, Na+, K+, Cl-, SO42-, NH4+, NO3-, HCO3-, CO32- , BOD5, SM and COD. The analytical data was compared to WHO standards. The Results show that the concentrations of the chemical elements are very high in the wastewater, but hardly exceed the levels recommended by the standards for agro-pastoral needs. Electrical conductivity indicates that 57% of the samples analysed are not saline. Phosphorus and potassium concentrations are low. There is a strong mineralization resulting from industrial or domestic pollution. The physicochemical characterization of the raw wastewater revealed that this liquid discharge is very heavy in organic matter in term of COD (Avg.= 341.52 mg/L), in BDO5 (Avg.= 260 mg/L), in Suspend Matter (Avg.= 307.6 mg/L) and mineral matter expressed in terms of chlorides (Avg.= 75.968 mg/L), electric conductivity (Avg.= 580.24 µs/cm) and alkalinity expressed as CaCO3 (Avg.= 220.70 mg/L) with a pH of 7.5 (±0.3). The average levels of nitrates and orthophosphates respectively of the order of 33.11 mg/L and 86.74 mg/L. Over the entire sampled site, most of the wastewater analysed is suitable for agriculture.

Impacts de la variabilité spatiale de l’occupation des sols sur l’érosion éolienne et les transports de nutriments dans le terroir de Banizoumbou (sud-ouest du Niger)

Abstract: Au Sahel, l'erosion eolienne cause des pertes en terres et en nutriments. Au Niger meridional, cette forme erosion est une cause majeure de la degradation de l'environnement. Le paysage de ce milieu est domine par une juxtaposition de surfaces exploitees sous culture pluviale, et de jacheres d'âges differents. L'objectif de ce travail est de quantifier les flux d'erosion eolienne et les transferts de nutriments associes en fonction du type d'occupation du sol sur une saison entiere. Il apparait que l'erosion eolienne est faible dans la jachere ancienne (Pi) du fait d'un fort couvert vegetal (80%). Cette occupation du sol a respectivement emis pres de 7 et 3 fois moins de flux d'erosion que le champ (Pc) et la jachere d'une annee (Pj). De meme, la somme des bases echangeables sur la jachere ancienne (2,669 Meq/100g) est superieure a celles sur le champ (2,085 Meq/100g) et la jachere jeune (2 Meq/100g). Ceci est lie, en particulier, au piegeage des particules et des nutriments associes transportes depuis les surfaces tres sensibles a l'erosion eolienne (champ et jachere jeune) par le couvert vegetal de la jachere ancienne.
