“…In contrast, moringa showed greater orientation towards sustainability, being a perennial tree that increases productive diversification, where biofertilizers and bioinsecticides are applied, as the leaves are the harvest product and for human consumption (Mota-Fernández et al, 2019). In addition, moringa does not require high application of agricultural inputs, compared to the high input demand of sugarcane, maize and citrus crops (Mrini et al, 2001).…”

Objective: To evaluate the sustainability of four agroecosystems in the state ofVeracruz, Mexico: sugarcane, maize grain, orange and moringa.Design/Methodology/Approach: Producers that provided information about thecrops’ management were located. Semi-structured interviews were conducted toidentify critical points affecting sustainability, and the indicators were weighted usingthe bottom-up criterion and the PSR model.Results: The most sustainable crop was moringa, and the least sustainable wasmaize for grain. Conventional crops are characterized by being monocultureplantations and demanding large amounts of non-renewable external inputs thatundermine their sustainability. Lack of technical training for producers was identifiedas a critical point.Study Limitations/Implications: The results obtained are limited to the analysis offour production systems and their environmental, social and economic dimensions.Findings/Conclusions: Moringa is presented as an alternative crop with lowenvironmental impact that generates employment and strengthens social capital.

“…The extraction of groundwater from wells consumes about half of the electricity utilized by India’s agriculture sector ( Singh, Mishra & Nahar, 2002 ). A major part of the energy consumed by irrigation is supplied by non-renewable fossil fuels ( Mrini, Senhaji & Pimentel, 2001 ; Topak et al, 2005 ). Dependence on fossil fuels, which are widely used to generate energy, could pose a threat to global food production growth and stability ( Deike, Pallutt & Christen, 2008 ; Pimentel et al, 2002 ).…”

The study was aimed at identifying the potential energy saving for groundwater pumping through enhanced efficiency of the pump sets. A total of 65 electrically powered tube wells were selected in the Sonipat district of the north Indian State of Haryana to study the energy use efficiency for groundwater pumping. The existing efficiency as well as the minimum expected overall efficiency of the tubewells were determined based on field survey, measurements, and applicable standard code of the Bureau of India Standards. The overall efficiencies of selected tube wells, computed based on actual measured power consumption, varied from 10.1% to 56.6% in the Sonipat block and 15.3% to 52.8% in the Rai block. The average energy requirement, for the selected tube wells, at the current efficiency level was 4,364.0 and 13,100.4 kWh for wheat and paddy crops, respectively, in the Sonipat block, while it was 3,424.8 and 10,280.9 kWh for wheat and paddy crops, respectively, in the Rai block. Analysis revealed that improving overall efficiency from the current level to the minimum expected level can lead to energy savings of 48.3% and 35.9% for tube wells in the Sonipat and Rai block, respectively. In the Rai block, where the groundwater level has declined significantly, the replacement of inefficient pumps should be done in tandem with crop diversification, improving water application efficiency and groundwater status by employing improved irrigation management practices and adopting groundwater recharge techniques.

“…Previous studies have compared the energy consumption of various irrigation technologies (Mrini et al 2001, Topak et al 2005, Chen and Baillie 2007, Baillie 2009). However, these studies fail to provide a complete picture as they have not analysed GHG emissions associated with the use of primary farm inputs, including farm machinery, fuels to run farm machinery and agrochemicals (fertilizers, manures, insecticides, herbicides, fungicides, plant regulators etc).…”

The Australian Government is currently addressing the challenge of increasing water scarcity through significant on-farm infrastructure investment to facilitate the adoption of new water-efficient pressurized irrigation systems. However, it is highly likely that conversion to these systems will increase on-farm energy consumption and greenhouse gas (GHG) emissions, suggesting potential conflicts in terms of mitigation and adaptation policies. This study explored the trade-offs associated with the adoption of more water efficient but energy-intensive irrigation technologies by developing an integrated assessment framework.Integrated analysis of five case studies revealed trade-offs between water security and environmental security when conversion to pressurized irrigation systems was evaluated in terms of fuel and energy-related emissions, except in cases where older hand-shift sprinkler irrigation systems were replaced. These results suggest that priority should be given, in implementing on-farm infrastructure investment policy, to replacing inefficient and energy-intensive sprinkler irrigation systems such as hand-shift and roll-line. The results indicated that associated changes in the use of agricultural machinery and agrochemicals may also be important.The findings of this study support the use of an integrated approach to avoid possible conflicts in designing national climate change mitigation and adaptation policies, both of which are being developed in Australia.
