Item Assessment of Rainfall Impact on Groundwater Vulnerability for Agricultural Production(Journal of Engineering in Agriculture and the Environment, 2024) Ngema, Hellen; Olago, Daniel; Opere, Alfred; Silas, OriasoThe research study was conducted in Northern Lake Victoria basin to assess rainfall impact on groundwater as a fresh water source on 30 farms for agricultural production. Depth Aquifer Recharge and Transmissivity (DART) index quantitative method was applied that revealed that rainfall was directly related to groundwater vulnerability index. Positive DART index was realized during long rainfall season between April and June, and during short rainfall season in September and October. The other months had negative values during dry season. DART indices ranged between -8.40 and 2.50 with positive values representing more resilience to negative impact of erratic rainfall. There were two groundwater vulnerability Index Thresholds of -8.40 and -4.80 that marked onset of long and short rainfall seasons respectively. Mann-Kendall trend analysis and t-test performed indicated a downward trend and a significant difference of groundwater vulnerability index values because of seasonal rainfall changes that caused wells to dry up thus increasing water insecurity. The research study results confirmed the severity of rainfall patterns on groundwater recharge that can affect agricultural production and food security to households.Item ENVIRONMENTAL HEALTH & DEVELOPMENT(Daystar University, 2019-01) Daystar UniversityItem ENVIRONMENTAL HEALTH EDUCATION AND EXTENSION(Daystar University, 2019-01) Daystar UniversityItem ENVIRONMENTAL HEALTH ADMINISTRATION(Daystar University, 2019-01) Daystar UniversityItem PARASITOLOGY(Daystar University, 2019-01) Daystar UniversityItem ENVIRONMENTAL SAMPLING AND ANALYSIS(Daystar University, 2019-01) Daystar UniversityItem OCCUPATIONAL HEALTH, SAFETY AND HYGIENE(Daystar University, 2019-01) Daystar UniversityItem ENVIRONMENTAL MICROBIOLOGY(Daystar University, 2019-01) Daystar UniversityItem INTRODUCTION TO ENVIRONMENTAL POLLUTION(Daystar University, 2019-01) Daystar UniversityItem BCL 402T: ENVIRONMENTAL LAW(2012-01) SCHOOL OF BUSINESS AND ECONOMICSSCHOOL OF BUSINESS AND ECONOMICS DEPARTMENT OF COMMERCE END OF SEMESTER EXAMINATION SEMESTER: JANUARY 2012 CODE BCL 402T UNIT: ENVIRONMENTAL LAWItem ENV 112X & Y: Environmental Science(2012) Department of Science and EngineeringDepartment of Science and Engineering ENV 112X & Y: Environmental Science End of January 2012 Semester ExaminationItem ENH120A: PRINCIPLES OF ECOLOGY(2012-01) SCHOOL OF SCIENCE, ENGINEERING AND HEALTHSCHOOL OF SCIENCE, ENGINEERING AND HEALTH DEPARTMENT OF SCIENCE AND ENGINEERING END OF JANUARY 2012 SEMESTER EXAMINATIONS ENH120A: PRINCIPLES OF ECOLOGYItem ENH 103: BASIC ZOOLOGY(2012-01) SCHOOL OF SCIENCE, ENGINEERING AND HEALTHItem PHY 112: Physical science(DAYSTAR UNIVERSITY, 2018-06) DAYSTAR UNIVERSITY, SCHOOL OF BUSINESS AND ECONOMICS DEPARTMENT OF COMMERCEItem MAT 120A COLLEGE ALGEBRA(DAYSTAR UNIVERSITY, 2012-01) DAYSTAR UNIVERSITY, SCHOOL OF SCIENCE, ENGINEERING AND HEALTHItem MATH 211 X: OPERATIONS RESEARCH(DAYSTAR UNIVERSITY, 2012-01) DAYSTAR UNIVERSITY, SCHOOL OF BUSINESS AND ECONOMICSItem MAT 322A: PROBALITY AND STATISTICS(DAYSTAR UNIVERSITY, 2012-01) DAYSTAR UNIVERSITY, SCHOOL OF SCIENCE, ENGINEERING AND HEALTHItem MAT 223A: Discrete Mathematics(Daystar University, 2012-01) Daystar UniversityItem MAT 223A: DESCRETE MATHEMATICS(DAYSTAR UNIVERSITY, 2012-01) DAYSTAR UNIVERSITY, SCHOOL OF SCIENCE, ENGINEERING AND HEALTHItem MAT 102 A - T Basic mathematics(DAYSTAR UNIVERSITY, 2012-01) DAYSTAR UNIVERSITY, SCHOOL OF BUSINESS AND ECONOMICS DEPARTMENT OF COMMERCE
