Abstract:Effective public policies are needed to manage a nation’s natural resources, including soil and water. However, making such policies currently requires a shift from a traditional qualitative approach to a mix of scientific data, evidence and the relevant social elements, termed data-driven policymaking. Nigeria, like most developing countries, falls short of the framework for this approach. Nevertheless, the lack of potable water in some regions and the continuous degradation of farmable lands call for interve… Show more
“…Since agriculture is the main component in the Egyptians' economy, and food security is significantly limited by soil and water resources, there is a growing need to develop effective policies for the long-term management of natural resources (Doro et al, 2020). Summer vegetable crops' growth is threatened by many factors such as water scarcity (Abdelsamie et al, 2012) and heavy weed infestation.…”
To manage natural resources and achieve agricultural sustainability, effective production strategies are required. For a healthier crop and a cleaner environment, reducing or eliminating chemical use is also a desirable goal. The goal of this study was to see how soil polyethylene mulch affected tomato crop output and quality. The Experimental Farm of the Faculty of Agriculture, Sohag University, Egypt, was used for two consecutive early summer seasons production. Manual weeding was used as a positive control treatment to compare its effect with black plastic mulch and herbicide on the growth, yield, and quality of two tomato hybrids (G.S-12 and Fayrouz). Weed density and biomass and economic profitability levels were also investigated. The use of black plastic mulch greatly enhanced all of the measured characteristics in both seasons, according to the data. i.e., vegetative traits, vitamin C content, total soluble solids, and N, P, and K leaves' concentrations. Data also revealed a superiority of G.S-12 hybrid over Fayrouz hybrid in most characters. Results showed a surprising effect for black plastic mulch treatment on smothering weed emergence compared with the conventional manual or chemical weed control treatments during the two seasons of considering. The hand-hoeing treatment proved to be the least viable weed control system among all treatments. This study recommends applying black plastic soil mulch in tomato production particularly in reclaimed soil conditions to reduce labor requirements and produce a higher, healthier output. In terms of gross margin and benefit-cost ratio (BCR) analyses, it also showed to be the optimum strategy.

“…To address this challenge, it is pertinent to assess potential sites' subsurface stratigraphic and hydrogeological conditions before establishing medium to large-scale fishponds to ensure that they would be capable of holding water year-round or would need to be engineered for such purpose [ 27 ]. Integrating such data-informed approaches into local fish farming in Nigeria would improve sustainable agriculture [ 32 ]. Fig.…”
“…The provision of potable water is one of the cardinal responsibilities of modern government (Japan International Cooperation Agency (JICA), 2014), which can be achieved by development of surface, (Kuria and Vogel, 2014), and ground water resources (Carrard et al, 2019). Abundant precipitation and good topography in a region may indicate that surface water source as being the better alternative to ground water source which is exhaustible (Doro et al, 2020;Healy et al, 2020;Salau and Salaudeen, 2017). Within the Bauchi Local Government Area (LGA), this is even more poignant considering the underlying basement complex rock formation which is known to have poor groundwater retentive capacity, transmission and large population base.…”

“…Advances in computer technology have made possible the development and use of simulation models in hydrology (Doro et al, 2020;Chandwani et al, 2015;Kumar and Tv, 2013). Normally, these models are sets of equations describing various phases of the rainfall-runoff processes and account for water balances through time, of which there are different types based on a wide range of characteristics.…”
The maximum yield of 90,000 m3 /day from the existing Gubi dam in Bauchi will barely meet the water demand beyond 2030 at an average water use of 100 litres per capita/day. For higher water demand of up to 250 litres per capita/day expected in an urban centre, the existing dam capacity is inadequate, and the demand should grow to 253,102 m3/day by 2037. This is the rationale for this study, which showed the feasibility of a new dam through technical reviews and analysis of topography, hydrology of the site, field and laboratory investigations, computer analyses and designs. Hydrologic simulation of rainfall-runoff processes for 57 years of rainfall data using the Soil Conservation Service (SCS) method gave an annual runoff volume of 59 Mm3 on a stream in Miri, which can be harnessed to assure adequate water supply in the metropolis. This will require the construction of a 25 m high embankment dam. Topographic survey and analysis indicated that the proposed site has good water retention capability. Although net flow adjustment analysis showed a high evaporation loss of up to 13.5 Mm3 annually, seepage loss is expected to be small in view of the underlying basement complex rock formation.
