“…It is estimated one billion people currently suffer from chronic hunger and that global food production needs to double when the global population will stabilise at around 9.8 billion in 2050 1,2 . Increases in agricultural output have been largely driven by raising the use-efficiency of labour, land, capital and other inputs, including fertilisers 3,4 , but further escalation in food demand will place increasing pressure on finite land and water resources, raising serious concerns over land use intensification and global food security [5][6][7] . The challenge of meeting sustainable food production while achieving the UN Millennium Development Goals of ending hunger and ecosystem protection is substantial [8][9][10] and has been described as "a perfect storm" 11 .…”

Agriculture's most pressing challenge is raising global food production while minimising environmental degradation. Nutrient deficiencies, principally nitrogen (N), limit production requiring future increases in fertiliser use and risk to proximal non-agricultural ecosystems. We investigated combining humate with urea, globally the most widely used N-suppling fertiliser, in a four-year field study. Humate increased pasture yield by 9.8% more than urea and significantly altered soil microbial diversity and function. Humate increased N retention suggesting microbial sequestration may lower N leaching and volatilisation losses. Humic microbial bio-stimulation could feasibly increase fertiliser efficiency and development of ecologically sustainable agriculture.

“…The model supports operational decisions about which route and transport mode to choose and also aids strategic considerations on where to locate a logistics node or infrastructure along a cold chain. Mc Carthy et al (2018) define in their review the four Pillars of Food Security. One of the important pillars is storage, with related high energy cost.…”

Factors causing peak energy consumption of reefers at container terminals

et al. 2019

Reefers are refrigerated containers commonly used for transporting perishable goods such as meat, fish, vegetables and fruit. Nowadays, reefers are responsible for 40% of the total energy consumption of container terminals, when connected to the electricity grid on shore. Every time when a large number of reefers is plugged-in after arrival, peaks in energy consumption occur. As container terminals purchase energy using a demand-based fee, exceeding the reserved capacity during peak times increases the energy costs of the terminal significantly. So far the literature has not dealt with the root causes of peak energy consumption of reefers, or ways to reduce these peaks. The aim of this paper is to identify the root causes and to quantify their importance. We use data of energy consumption of reefers at a large container terminal, over the period of 1 year. In order to identify the importance of factors, we apply a sequential multiple regression analysis approach with backwards feature selection. Variations in energy demand are explained for 77% by the arrival pattern of containers, for about 5% by dwell time and for 2% by other factors, such as container temperature at plug-in. Promising approaches to reduce peak energy consumption of reefers includes dynamic pricing, energy management and specific peak shaving strategies.

“…The main challenges of the food industry are obtaining a trade-off between product price versus safety, quality, variety, and demand. To address these challenges, industry professionals are required to focus on each major area where a product is processed, stored and distributed (Lorenzetti et al, 2015(Lorenzetti et al, , 2018Carthy et al, 2018).…”

The processing steps as scalding and de-feathering in the poultry industry have a great impact in meat quality. In this sense, the aim of this work is to evaluate the temperature effect (52, 57 and 62ºC), broiler weight (2.4-2.6, 2.8-3.0 and 3.2- 3.4 kg) and broiler processing line speed (4.000, 6.500 and 9000 broilers/h) of the scalding and de-feathering in the meat quality. An experimental design 23 was employed to evaluate the physical characteristics (absence of torn breast skin, epidermis, feather on wing and uropygium), color (L*, a*, b*), texture profile (hardness, adhesiveness, elasticity, cohesiveness, gumminess, chewiness, and resilience), and pH of broiler breast fillets. The pH did not suffer significant effect (p>0.05) of the variables between the ranges studied. In general, the better meat quality was obtained at 57°C scalding temperature, 3.0-3.2 kg weight and 6500 broilers/h processing line speed. In addition, these conditions are applicable to removal the epidermis, feather on wing and uropygium.
