“…India is vulnerable to climate change in view of the dependence of its huge population on agriculture, excessive pressure on natural resources, and poor coping mechanisms (Sikka et al, ). Agriculture plays a vital role in the Indian economy; it accounts for 18% of India's gross domestic product (GDP) (Madhusudhan, ) and 55% of the population is dependent on agriculture (Kumar et al, ). Hence, any change in crop conditions, including the fact that nearly 52% of the total cultivated area is under rainfed agriculture, is likely to affect the overall economy of the country (Naresh Kumar et al, ; Parmeshwar et al, ).…”

An integrated farming system (IFS) aims to sustain agricultural production, maintain farm incomes, safeguard the environment and respond to climate change impacts. Experiments in a tribal farmer's fields during 2016–2018 with two IFS models (pulse and cotton) were conducted in the Telangana region, India. An on‐farm reservoir (OFR) is designed for storing surface runoff based on the area and runoff coefficient determined through a modelling approach. The results demonstrated how supplemental irrigation and water harvesting are the most important and proven technologies for improving crop productivity and the efficient use of water in dryland areas of the semi‐arid tropics. The economic analysis indicated that after introduction of OFR technology, farmers' profits were increased under both scenarios of prolonged and short dry spells. According to the results, adoption of the OFR and IFS models not only ensured economic returns but provided regular employment even on less than 1 ha of land, which is usually non‐sustainable if monocropping is being practised. The approaches used in this work might be useful for guiding producers’ decisions in optimizing resources and selecting crops based on economic and water use efficiency. © 2020 John Wiley & Sons, Ltd.

“…Drip irrigation has been highlighted in this context, since the flow rate and operating pressure of the system are lower when compared to sprinkler irrigation systems. According to Kumar et al (2015), drip irrigation technologies are widely considered as one of the most effective and efficient method of irrigation when properly designed and operated.…”

ABSTRACT:In this study we designed and evaluated a microtube irrigation kit, pressurized by a pump powered by solar energy; and presented the cost of the developed kit. The kit consisted of irrigation laterals, positive displacement pump, photovoltaic generator, battery, charge controller and solenoid valves. The first step was to design microtubes and lateral lines to compose a kit, followed by selecting the appropriate pump. After testing the pump in laboratory conditions, four lateral lines were installed on beds cultivated with lettuce in order to evaluate their performance in field conditions. In both, laboratory and field conditions, the kit presented uniformity greater than 94%. Estimates indicated that the selected pump could irrigate up to 15 beds (270 m²), though its efficiency did not overcome 10.8% on the evaluated conditions. During days of long irrigation routine, the pumping system presented efficiency of 9.7% for the motor pump set, 36.6% for energy conversion and 2.4% for the overall system. The total fixed cost of deployment kit developed for irrigation of 15 beds was R$ 4,313.33, including irrigation controller and solenoid valves, or R$ 3,083.33 without these items. Therefore, the kit developed was considered technically feasible for lettuce irrigation. Estimativas mostraram que o conjunto de bombeamento selecionado é capaz de irrigar até 15 canteiros (270 m²), apesar da sua eficiência não ter sido maior que 10,8%. Para os dias com maior tempo de irrigação, o sistema de bombeamento apresentou eficiências de 9,7% para o conjunto motobomba, 36,6% para a conversão de energia e 2,4% para a global. O custo fixo total de implantação do kit desenvolvido para a irrigação de 15 canteiros foi de R$ 4.313,33 com controlador de irrigação e válvulas solenoides, ou R$ 3.088,33 sem esses itens. Assim, o kit desenvolvido mostrou-se tecnicamente viável para irrigação de alface.

This investigation focused on the research undertaken on solar photovoltaic (PV) and solar thermal technologies for pumping water generally for irrigation of remote rural farms specifically considering the Sub-Saharan African region. Solar PV systems have been researched extensively for irrigation purposes due to the rise in Oil prices and the upscaling in commercialisation of PV technology. Based on the literature the most effective PV system is presented for the irrigation of a small scare remote rural farm with respect to the cost, pumping capacity and system efficiency. Similarly, solar thermal systems are reviewed and the most effective system described. Unlike PV technology, solar thermal technology for water pumping is lacking especially in small scale operations. However, with the possibility of local production, low investment cost, easy maintenance and lower carbon footprint, solar thermal water pumping technologies may be able to overcome the shortcomings of the PV technology that has stopped widespread use of the technology for irrigation applications. Taking into consideration recent developments in concentrated solar technologies using the Stirling engine, novel solar thermal water pumping systems may be developed. This review also highlighted the different methodologies such as modelling, used to investigate and optimise the performance of solar powered systems.
