“…Furthermore, the use of North-South horizontal axis solar trackers, that provide a constant daily profile of PV power, allows a better matching with the dynamic of the well [11], [12], [13]. Finally, the decrease in the cost of the PV module [14], the exclusión of batteries and the increase in the price of conventional electricity [15], [16] makes this solution more competitive [17], [18], [19], [20] with some real-scale experienees showing cost savingsof80% [7], [21].…”

This paper presents a new method for selecting a pump for large-power PV irrigation systems working at a variable frequency. This can have a significant impact since the traditional way of selecting the pump is based on maximizing the efficiency of pump in the duty point at a certain single operating frequency, which is not useful for PV irrigation systems working at a variable frequency. The proposed method starts by considering the pumps with H-Q curves with a high slope and the duty point in the right-hand third of the curve to assure a wide range of operating frequencies. Then, the efficiency within the whole range of frequencies is evaluated. An example of a performance comparison between the pumps selected with the new and traditional methods has been carried out. Results show that by using the new method, the yearly volume of water pumped increases by 7.2-21.0%) and the pump efficiency by 4.3-5.3%). Finally, it is important to mention that the proposed method has already been implemented in the SISIFO tool, able to simúlate PV irrigation systems.

“…Also, electrifying pumps increase investment in irrigation by 28% and output by 2% (Binswanger et al, 1993) while, subsidy removal in electricity causes food inflation (R. Bhattacharyya & Ganguly, 2017). Thus, Langarita, Chóliz, Sarasa, Duarte, and Jiménez (2015) advocate for a low tariff on electricity to the rural dwellers.…”

Despite having vast farmland suitable for paddy rice farming, local production in the country is weak, especially in Kano where the state has the most abundant farmland put to rice farming and the most extensive rice farmers in the 36 states of the country. As such, over 4mm/t of milled paddy rice has to be imported annually into Nigeria to supplement home production. The economy cannot sustain rice import because it depends on crude oil revenue; thus, leading to scarcity of rice at an exorbitant price. The study was conducted in the 2018 cropping season for rainfed and irrigated paddy rice, to identify the impact of rural infrastructure on the productivity of rice farmers in Kano State, Nigeria. There are seven local governments with 17 rice clusters in the state that are cultivating rice. A random sample of 768 rice farmers was selected in 9 rice clusters from the population of 135,895 rice farmers using multistage and purposive sampling. Using the Statistical Package for Social Science (SPSS) software version 22, data screening and preliminary analysis was conducted, aimed at satisfying the assumptions of the multivariate analysis. Thus, missing data analysis was performed to identify univariate outliers and multivariate outliers. Likewise, normality skewness and kurtosis, as well as multicollinearity issues, were checked. The preliminary analysis indicates that the data fulfil the conditions of multivariate analysis, thus, suitable for inferences.

“…The relation between the farming sector and energy has been discussed in previous research such as [103] where the potential for the utilisation of biogas was demonstrated and [104] where the use of agricultural biomass in CHP has been presented on a study for Serbia. In another case study [105] the effect of increases in electricity costs on 58 farming communities in north-eastern Spain are investigated and changes in the current tariff structure as well as increases in articles, such as energy intensity, with all the positive and negative aspects of using it [107]. Some research articles have analysed various parameters influencing energy development and have also defined a level of sustainable energy development, for example on a case study for Western Balkan countries [108].…”
