Agricultural production is affected by variations in weather conditions and long-term climate patterns. The pattern of changing climate in the last three decades indicated that changes in rainfall and temperature reduced agriculture outputs and yields, which is significant in rice. A farm experiment was set up with six cultivars of rice. The APSIM model was used to simulate grain yield at maturity under a change in temperature scenarios to observe the effect of climate change on rice. Results showed that the mean annual temperature in KRIS has risen by about 0.62 degrees in a decade, while a rise of 0.9 degree Celsius between “2010-2040” respectively. Also, there was no significant difference in the measured yield between the rice varieties, however, their response to a change in temperature in the simulated yield is significant. effect of decreased temperature on the rice yield within the span of two deca...

For example the widely used quantitative metrics for irrigation water allocation performance assessment include equity, adequacy, and reliability of water supply. However, a qualitative metric that is seldom applied particularly in Nigeria is the value engineering method. A value engineering method is problem identification and solving approach commonly used to analyze the level of functionality of a given system or its components. The approach comprised the following phases; problem identification, system functionality analysis, creation, evaluation and development of value alternatives. A value engineering approach was applied to identify and solve the water allocation problem at Watari Irrigation Project (WIP), Kano Nigeria. Eleven (11) major problems related to water allocation were identified, and 27 sol...

Ordinarily, soils are assigned with K factors depending on geological properties only which can result into erroneous calculation of soil erosion. This study explores roles of different agricultural land use on the spatial variability of soil erodibility on hilly farms at Cameron Highlands. Soil samples, slopes and spatial locations were collected based on crop types being cultivated. Meanwhile, the land use and type of equipment for each crop are recorded and ranked depending on the degree of soil disturbances. The results showed that, K values are ranged from 0.0084 to 0.0161. Shallow-root crops, such as vegetables and flowers have higher K values due to shallow soil rootzone and frequency of surface operations. However, tea cultivated areas and forests have low K values, indicating comparably higher ability to resist erosion. Furthe...

The experiment consisted of four levels of irrigation water application depth of 100%, 75%, 50% and 25% replacement of moisture depleted and three irrigation intervals (7, 14 and 21 days) combined in Randomized Complete Block Design in a Split plot arrangement and laid as treatments in plots (3 m x 3 m basin) and replicated three times. Irrigation water was applied to each basin using a calibrated PVC pipe. The soil moisture was monitored throughout the crop growing season with theta probe. The crop canopy temperature (Tc) in the experimental plots was measured with a portable hand-held infrared thermometer. The dry and wet bulb temperatures were measured with an aspirated psychromet...

Deficit and constant loss (DCL) method has been introduced in Hydrologic Engineering Center's Hydraulic Modeling System (HEC-HMS) model for continuous based simulations. However, studies on climate change impacts using the method are still very few. This study used the method to evaluate potential impacts of climate change on streamflow at Bernam Basin, Malaysia for 2010-2039, 2040-2069 and 2070-2099 to the baseline period (1976-2005) under two RCP scenarios (RCPs 4.5 and 8.5). The model efficiency during evaluation is found satisfactory. Compared with the baseline period, the predicted streamflow decreased in all future periods during main and off-seasons. However, the changes have become more pronounced during the off-season with a significant decrease of 9.14% under the worst-case scenario (RCP8.5). Therefore, the Basin would likely experience tremendous pres...

The AquaCrop model was firstly calibrated using the data obtained from the field and was later used to simulate the observed yield, water productivity and biomass of tomato. The Root Mean Square Error (RMSE), Coefficient of Residual Mass (CRM) Normalized Root Mean Square Error (NRMSE) and Modelling efficiency (EF) were used to compare the observed and simulated values. The governing equation of AquaCrop simulation software was then optimized using the evolutionary optimization method of GA with MATLAB programming software. All the statistical indices except CRM used in comparing the simulated and observed values indicated good agreement. The CRM values of -0.11, -0.06 and -0.20 were obtained for the yield, biomass and water productivity of tomato which indicated a very slight over-estimation of the observed results by the AquaCrop model. The optimiza...

Explaining and characterizing these sociohydrological phenomena is a central focus of Panta Rhei–Everything Flows, the Scientific Decade of the International Association of Hydrological Sciences (2013-2022). Here we use System Dynamics’ archetypes to describe and classify socio-hydrological phenomena emerging from nonlinear interactions between human and water systems. Archetypes illustrate dynamic behaviours that are frequently observed across (seemingly) different systems, contexts or problem settings. They include intended or unintended actions and reactions with explicit recognition of delays in reaction times. Reinforcing (or positive) and balancing (or negative) feedback loops and system boundaries are key elements for describing archetypes. In the study of human-water systems, the most common archetypes are Limits to Growth, Fixes that Backfire, Success to the Successful, and Tragedy of the Commons. Using system archetypes to generalize the phenomena in coupled human-water systems allows for the comparison among case studies along with the integration of multiple dimensions, thereby contributing to the development of new theories which provide common causes and explanations. We first present several classes of sociohydrological phenomena that have been explored over the past decade, and then discuss their role in explaining the dynamics of human-water systems. Finally, we engage with the implications for integrated water resources management, hydrological risk reduction, and water governance.</p>

In northern Nigeria, irrigation has long been identified as the key to achieving the much-desired increase in food production to meet the ever-increasing population. However, the existing irrigation schemes encountered several challenges coming from different dimensions including economic, social, environmental, institutional and technological. To attain sustainable crop production, this paper attempts to uncover the underline challenges confronting irrigation schemes in northern Nigeria that cut across sustainability pillars. The findings revealed that irrigation schemes contributed immensely toward achieving food security and improving the well-being of rural dwellers. However, the huge investment in large- and medium-scale irrigation schemes have resulted in massive economic losses. This could be attri...

Some of these unlawful activities include unauthorized water abstractions, wastage, excessive losses, discharging untreated wastewater, over‐application of chemicals and fraudulent incidences. Despite advances in WRS planning and operational analysis, incorporating such undesirable activities to quantitatively assess their impact on WRS performance remain elusive. This study was then inspired by the need to develop a methodological framework for WRS performance assessment that integrated human impacts with WRS analysis tasks. A conceptual framework for assessing the impact of human behaviour on WRS performance using the concept of socio-hydrology is proposed herein. The framework identifies and coupled four major sources of water values (WRS, goals, managers and users) using three activities se...

This study evaluated the Aqua-Crop model using Onion crops under deficit irrigation and mulch practices in semi-arid Nigeria. Measurements were taken from the experimental plots which consisted of irrigation and mulch each at 4 levels were used to evaluate the Aqua-Crop model using canopy cover, biomass, yield, actual crop ET, and water productivity of Onion during the 2021 irrigation season. The simulated results from the Aqua-Crop model were evaluated and statistically compared with the experimental results. The model simulated canopy cover with the highest degree of correlation coefficient (0.74 ≤ r ≤ 0.94). The model perfectly predicted Onion yield and biomass under full irrigation irrespective of the mulching. However, the model underestimated Onion yield and biomass at de...

This paper presents the outcome obtained from a review to provide proactive measures that will combat the problems of water scarcity through the adoption of sensor-based drip irrigation by small-scale farmers. The small-scale farmers constituted the larger proportion of the farming population in the region. The paper is centred on the general overview of irrigation practices, advances in irrigation systems, modelling irrigation and cropping Systems, coupling soil sensors with drip irrigation and their adoption. Factors that hinder the acceptance and adoption of sensor-based drip irrigation systems were reviewed and synthesized which include initial capital investment, farmers’ awareness, risk perception and uncertainties, technical know-how, farm size and capital recovery. A simple framework for adopting a sensor-based drip irrigation ...

The estimated power required for the (Livestock Port) is 5MW, which will be mainly produced by a hybrid renewable energy system of (solar+ wind) energies. A standby power is required to be produced from biogas and batteries to cover approximately 10% of the estimated 5MW power i.e. 500kW, out of which 250kW will be generated from a biogas plant. Since the activity of the port is relying on exporting livestock, the biogas production will be a by – product which can be produced due to the transient stay of animals (mainly sheep) in the port. The paper made use of the comparison of six different animal dungs in producing biogas under anaerobic conditions. Sheep dung was found to produce the greatest amount of biogas compared to the other animals. Two types of energy production from biogas were discussed i.e. gas turbine generator and the mix of biogas with diesel in diesel e...
