    Evaluation of Loggers’ Knowledge of Environmental Consequences of Logging in Kwarra, Wamba L.G.A, Nasarawa State
    (Department of Environmental Management, Nasarawa State University Keffi, 2020-06-06) Adana, Mohammed Yusuf; Dahiru, M.K.; Alkali, Mohammed; Umar, Nasiru
    Evaluation of loggers’ knowledge of environmental consequences of logging in Kwarra, Wamba L.G.A, Nasarawa State. Stratified sampling technique was employed for data collection. The sample points were stratified into 23 villages where each village represents a stratum. The result obtained from the respondents’ knowledge on the impact of logging on the environment revealed that 51.7% of the respondents are aware of the fact that logging can pose significant impact on the environment while 48.3% are ignorant. Out of the number of the respondents that are aware of the impacts or effects of logging on the environment, 44.4% of them cannot say specifically what constitutes the impacts. However, it is also revealed that much of the impacts was related to soil erosion; while degradation, change in the amount of oxygen, absence of some medicinal plants and economic trees accounts for only 4.4%, 2.2%, 2.2% and 2.2% respectively. The study concluded that the Loggers in Kwarra District are not ignorant of the impacts of logging on the environment; despite the knowledge of the impacts, but could not do anything to mitigate the impacts. So, the study recommended that policies and laws that support conservation of natural resources should be fully implemented.

    GEOSPATIAL ANALYSIS OF HYDROLOGIC RESPONSE UNITS OF FLOOD INUNDATION AT DIFFERENT SUB-BASINS PARAMETERS IN TERENGGANU WATERSHED, MALAYSIA
    (Department of Environmental Management, Nasarawa State University Keffi, 2022-01-01) Alkali, Mohammed; Sufiyan, Ibrahim; Dahiru, M.K.
    Flood is one of the natural events in our environment. It destroys and displaces naturally existing structures found within the Hydrologic Response Units (HRUs). These include the Land Cover/Land use, Soil structure and the topography or the terrain. The method applied was the used of ArcSWAT to determine those flooded sub-basins by simply delineating the whole watershed into different sub-basin parameters. The result proves that what determines the flood influence was the area of the sub-basin that contained the HRUs not the HRUs itself. Once the sub-basin was inundated, the flooded streams within the sub-basins were calculated as flood impact, in this analysis 5 number of sub-basins were flooded in the watershed of Terengganu. Sub-basin number 3 has the highest flood impact with 14,699 hectares and sub-basin number 5 has the lowest total flood impact of 968.82 hectare.

    GEOSPATIAL TREND ANALYSIS OF RAIN-FED AND IRRIGATION PRACTICES FOR CROPS YIELD IMPROVEMENT IN KURA AND MINJIBIR, KANO STATE, NIGERIA
    (Department of Environmental Management, Nasarawa State University Keffi, 2022-01-03) Dahiru, M.K.; Sufiyan, Ibrahim; Alkali, Mohammed
    One of the advancements in Agriculture in recent time is the boost of crop yield to increase the number of output and feed the growing Nigerian population. The higher the output the less cost of food items and the more the food security. Kano State is one of the focal point not only on rain fed Agriculture alone but in irrigation farming. Irrigation was adopted coupled with soil fertility, most major crops such as Sorghum Bicolor, Maize, Millet, Beans and Groundnuts are typically grown during rainy season, while market garden crops such as Tomatoes, Pepper, Onion and Rice are now cultivated during the dry period in large hectares of land. This study focuses on different crops yield and its spatial distribution; to calculate the total crop yield per hectare and ascertain the duration of bumper harvest using trend analysis and normal probability. The result indicated more turn-out of farmers with double output of both rain fed and irrigation crops from 2019 and 2020 in two major local government area of Kano State Nigeria.
