-Introduction. The cultivation of high-value fruit species is a profitable agricultural activity in many tropical countries; however, intensive fruit cultivation may depend on high amounts of external inputs. The objective of our study was to quantify and compare the resource use during the cultivation of eight tropical fruit species (Rubus glaucus, Solanum quitoense, Passiflora edulis, Cyphomandra betacea, Physalis peruviana, Ananas comosus, Persea americana and Mangifera indica) commonly cultivated in Colombia. It further aimed to identify greenhouse gas (GHG) emissions in the selected production systems and to highlight the potential to contribute to climate change mitigation efforts. Materials and methods. The analysis was based on data from agricultural databases and applied a life-cycle assessment with energy use and GHG emissions as impact categories. Furthermore, economic indicators were taken into account with the aim of integrating the environmental and economic goals of production systems. Results and discussion. Among the eight fruit species studied, mango (Mangifera indica) was found to have the lowest and tree tomato (Cyphomandra betacea) the highest emission profile. The variability in resource use among growers of the same species was high, indicating the need to improve management abilities at the farm level. Mineral fertilizer production was the highest contributor to GHG emissions. GHG-and energy-efficient management alternatives would have a high potential to reduce the carbon footprint of fruit cultivation. Colombia

“…Previously, this type of information has not been available to PKO producers. An overview of the literature reveals that there are no publications concerning the energy usage in PKO plants, where as literature is replete with information on energy usage in plants processing beverage (Akinbami et al , 2001), rice (Chang et al , 1996; Ezeike, 1987), cashew‐nut (Jekayinfa and Bamgboye, 2003), tea (Baruah and Bhattacharya, 1996; Palaniappan, 1993; Palaniappan and Subramanian, 1998), sugarbeet (Mrini et al , 2002), spinach (Chinnan et al (1980) and poultry (Whitehead and Shupe, 1979).…”

Direct energy utilization in nine palm‐kernel oil (PKO) mills located in Southwestern Nigeria was analyzed. The mills were stratified into small, medium and large‐scale categories, based on their modes of operations and production capacities. Evaluation of energy usage was carried out in the seven readily defined unit operations namely: palm‐nut drying, palm‐nut cracking, palm‐kernel roasting, palm‐kernel crushing, PKO expression, PKO sifting and PKO bottling/pumping. PKO extraction rates in the three mill categories were evaluated. The average PKO extraction rate for small, medium and large mills were 48.45 percent, 42.68 percent and 36.24 percent, respectively. The total energy expenditure in small, medium and large‐scale PKO mills were 350.89MJ/tonne, 230.70MJ/tonne and 181.74MJ/tonne, respectively. This suggests that the unit energy requirement for PKO output decreases as mill capacity increases. The four most highly energy‐intensive operations identified were palm‐nut cracking, palm‐kernel roasting, palm‐kernel crushing and PKO expression, altogether accounting for 95.29, 92.14 and 93.65 percent of total energy used in small, medium and large‐scale mills, respectively.

“…They submitted that a tea garden required an estimated 18,408 MJ/ha of human energy in the first year. Other similar works reported in literature relating to evaluation of energy efficiency in processing industries include cashew-nut processing in Nigeria (Jekayinfa & Bamgboye, 2003, 2006; palm-kernel oil processing in Nigeria (Jekayinfa & Bamgboye, 2004, 2007 rice production in Bangladesh (Islam, Rahman, Saker, Ahduzzaman, & Baqui, 2001) sugar-beet production in Morocco (Mrini, Senhaji, & Pimentel, 2002) and, energy and labour use in Italian agriculture (Pellizzi, 1992). This study was undertaken to investigate the energy use pattern in the selected cassava processing mills in southwestern Nigeria and to develop predictive models that could estimate and optimize the energy demand of each unit operation for different selected cassava products.…”
