    Opis:
    There are ample facts that the whole world is facing an ecological crisis by reason of heavy deforestation. Thus, this study assesses the influence of deforestation on some selected villages in Borgu Local Government Area, Niger State. Data were collected from members of the community using a set of structured questionnaire. This was then analyzed using descriptive statistics (percentages and frequency count). Findings reveal that the major occupation is trading (33.3%), followed by farming (30%). The causes of deforestation in the study area include: fuelwood removal (31.7%), urbanization (25.0), logging (20.0%), subsistence farming (15.8%), population growth and overpopulation (3.3%), commercial farming (2.5%) and inequitable distribution of wealth and power (1.7%). Global warming (31.7%) was the major effect generated by deforestation in the study area, followed by soil erosion (24.2%). Encouragement of better agroforestry practices (30.8%) was seen as the major strategy for reducing deforestation by the respondents. Other best practices include: afforestation (27.5%), public enlightenment (13.3%), enforcement of forest land and policy (12.5%), forest education (8.3%), forest conservation and preservation (7.5%).

    Opis:
    Water contamination and pollution pose health hazards to humanity and hence the need for their treatment. This study compared reverse osmosis (RO) and ultra-violet (UV) radiation in treating borehole water (BHW) and surface water (SW). The study area is Omoku community in Rivers State of Nigeria. The RO- and UV-treated waters were determined by their physicochemical characteristics and total Coliform, with the control to check the impact of each one. The obtained results showed slight variations, which were either significant or not. The pH of the treated BHW was slightly acidic with the value of 6.52. Water conductivity ranged from 40.33 µs/cm3 to 42.40 µs/cm3 for the BHW treated with RO, UV and control samples, respectively. SW conductivity attained a range of 425.07–800.0 µs/cm3. Turbidity of BHW were beyond the detectable limit but was higher than the WHO limit of <5.00NTU, while total suspended solid (TSS) of SW ranged from 9.08–46.43 ppm. Total dissolved solids (TDS) values of water were between 3.50 ppm and 16.67 ppm for RO treated BHW and higher than that of SW. There was a reduction of salinity of BHW from 40.7 mg/l to 11.8 and 21.6 mg/l following RO and UV treatment, while SW salinity was also reduced from 75.0 mg/l to 20 mg/l in RO treated water and 16 mg/l in UV treated water. In this study, RO and UV water treatment proved to be effective in producing potable water from both BHW and SW, although RO seemed to produce water with reduced mineral content in comparison to the UV treatment. Both methods effectively reduced heavy metals as well as Coliform. The physicochemical parameters tested were below the WHO recommended limits in most cases. It is recommended that both methods be incorporated in a single WT in order to gain the benefits of both technologies.

    Opis:
    This paper described and contextualized participatory development of demand-driven curriculum for career-ready e-extension services in Nigeria as introduced by the Sasakawa Africa Fund for Extension Education. The stages of participatory development were participatory need assessment, participatory stakeholders’ workshop and validation among 124 stakeholders selected as key informants in relation to agricultural extension training, delivery, end users and policy makers. The stakeholders were grouped as follows: community leaders and policy makers; extension agencies / organisations / institutions / employers; farmers; input suppliers / marketers / agro-based traders / other value actors; and potential candidate groups. Stakeholder meetings were held separately with different groups three times, and then a combined meeting took place. The aggregated major decisions/consensus were subjected to content analysis using ATLAS.ti. The validation process included reading of each agreed decision to all participants, then participants indicated their agreement or otherwise, which led to either rejection or acceptance of the decision. This paper concludes that participatory curriculum development has enhanced the stakeholders to identify areas of demand-driven training in response to community needs. The stakeholders preferred more online than face-to-face training. The major perceived advantages of e-extension were reduced risk, time and cost effectiveness while infrastructural and human challenges were the perceived challenges that could possibly hinder the smooth running of eextension.
