The intensive agriculture system is prominent in the mainstream production technique of Bangladesh. The paper illustrates the contests of the traditional production system of Khasi about mainstream social and economic expectations of resource use. The specific Khasi adaptation process and the patterned dependency on available environmental resources can be observed in the traditional Khasi production practices. Meanwhile, the logic on the need for intensive production has been rising in the changing socio-economic resource maximization process towards sustainability. The impact of the mainstream trends of agriculture practices on a small-scale economy has been analyzed here with the changes in labor mobility, mechanism of labor control, production cost, and hierarchy issues of the traditional production system. The research findings reflect that modernity initiatives have changed the social and natural support system in production, and changes occur in the system through the market-induced priority of development. The production process is trending towards intensive cultivation. Whether a generalized community, i.e., dependent on multiple natural yielding, diversified forest resources, and social value-oriented cultivation system, can continue the traditional living in a staple food dominated mainstream agro-economy. The study shows that intensive production is growing in the traditional production field of Khasi with modern technologies. As the ongoing production process is found segmented and capital intensive, the research suggests the community-based production behavior to defend the vulnerability of the economic capital-poor Khasis of Bangladesh.

To overcome pandemics, such as COVID-19, vaccines are urgently needed at very high volumes. Here we assess the techno-economic feasibility of producing RNA vaccines for the demand associated with a global vaccination campaign. Production process performance is assessed for three messenger RNA (mRNA) and one self-amplifying RNA (saRNA) vaccines, all currently under clinical development, as well as for a hypothetical next-generation saRNA vaccine. The impact of key process design and operation uncertainties on the performance of the production process was assessed. The RNA vaccine drug substance (DS) production rates, volumes and costs are mostly impacted by the RNA amount per vaccine dose and to a lesser extent by the scale and titre in the production process. The resources, production scale and speed required to meet global demand vary substantially in function of the RNA amount per dose. For lower dose saRNA vaccines, global demand can be met using a production process at a scale of below 10 L bioreactor working volume. Consequently, these small-scale processes require a low amount of resources to set up and operate. RNA DS production can be faster than fill-to-finish into multidose vials; hence the latter may constitute a bottleneck.

The paper defines replenishment time based on the leveled consumption controlled loop in production system. Then it proposes a method of Kanban calculation. Traditional production system dose not consider leveling principle, thus the replenishment time is not accurately and more likely to double or miss counting number of Kanban. In the paper, Replenishment time is specified into more parts to reflect all influence in production process, and leveling combined with consumption controlled loop is taken into consideration for the replenishment definition. A new defined replenishment time is a base of Kanban calculation. A method of Kanban calculation could be built. It could decrease the possibility of double or miss counting number of Kanban. A case study is given to prove feasibility of the method of Kanban calculation.

Abstract Purpose Global food production needs to increase to provide enough food for over 9 billion people living by 2050. Traditional animal production is among the leading causes for climate change and occupation of land. Edible insects might be a sustainable protein supply to humans, but environmental life cycle assessment (LCA) studies on them are scarce. This study performs an LCA of a small-scale production system of yellow mealworms (Tenebrio molitor) in Central Europe that are supplied with organic feedstuff. Methods A combined ReCiPe midpoint (H) and CED method is used to estimate the potential environmental impacts from cradle-to-gate. Impact categories include global warming potential (GWP), non-renewable energy use (NREU), agricultural land occupation (ALOP), terrestrial acidification potential (TAP) and freshwater eutrophication potential (FEP). The robustness of the results is tested via sensitivity analyses and Monte Carlo simulations. Results and discussion Impacts related to the production of 1 kg of edible mealworm protein amount to 20.4 kg CO2-eq (GWP), 213.66 MJ-eq (NREU), 22.38 m2 (ALOP), 159.52 g SO2-eq (TAP) and 12.41 g P-eq (FEP). Upstream feed production and on-farm energy demand related to the heating of the facilities are identified as environmental hot-spots: Depending on the impact category, feed supply contributes up to 90% and on-farm heating accounts for up to 65% of overall impacts. The organic mealworm production system is contrasted with a selected Austrian organic broiler production system, to which it compares favourably (18–72% lower impacts per category), with the exception of freshwater eutrophication (6% higher impacts). Conclusions This case study shows that the Austrian mealworm production system compares favourably to traditional livestock systems. Compared to LCAs from large-scale T. molitor rearing facilities in France and in the Netherlands, however, the Austrian production system cannot compete for the reasons of production scale, feed conversion efficiency and type of production system. Nevertheless, the investigated mealworms represent a sustainable protein alternative that should be added to the Western diet.

Much of the world's rangelands contribute to food production through extensive grazing systems. In these systems, livestock producers, pastoralists, and ranchers move grazing animals to access variable feed and water resources to create value while supporting numerous other ecosystem services. Loss of mobility due to political, social, ecological, and economic factors is documented throughout the world and poses a substantial risk to rangeland livestock production and conservation of rangeland resources. The integration of production-scapes can facilitate livestock mobility through transportation and trade. This paper describes the beef cattle production system in California, where transporting and marketing animals integrate an extensive grazing system with intensive production systems, including feeding operations. Analysis of livestock inspection data quantifies the magnitude of livestock movements in the state and the scope of production-system integration. Over 500,000 head−47 percent of the state's calf crop—leave California rangelands and are moved to new pastures or feedyards seasonally over a 12 week period each year. Most ranchers in California, from small-scale producers (1 to 50 head) to larger producers (more than 5,000), participate in the integrated beef production system. Less than 1% of steers and heifers go from rangeland to meat processing. Like pastoralists, ranchers strategically move cattle around (and off) rangeland to optimize production within a variable climate. Ranchers indicate that their movements result from changes in forage quality and quantity and support their desire to manage for conservation objectives, including reducing fire fuels, controlling weeds, and managing for wildlife habitat. Inspection data, as well as direct observation, interviews, and surveys within the San Francisco Bay area, reveal the extent to which the region's ranchers rely on saleyards to facilitate the movement of cattle and integration of production systems. Saleyards and cattle buyers drive beef production efficiency by sorting, pricing, and moving cattle and matching them to feed resources in more intensive production systems. However, transactions lack traceability to inform policy and consumer choice. New data technologies like blockchain can provide traceability through integrated production-scapes and facilitate market development to support grazing landscapes and consumer choice.

The snail Pomacea patula catemacensis is an endemic mollusk from the southeast Gulf of Mexico, which is commercially exploited and in decline since 2010. This decline is associated with an increasing market demand and illegal capture. We designed a small-scale production system for P. p. catemacensis and determined its financial feasibility for a base scenario. We used information gathered from stakeholders and stochastic modeling to predict the impact of uncertain variables on the economic indicators to assess the financial viability under varying conditions. The small-scale intensive production system, designed to yield 3.9 tons/year of unshelled product, requires an investment of about US $65,000. The production unit was financially assessed using the Modified Internal Return Rate and The Net Present Value of cash flow, considering a 14% discount rate and a 7% reinvestment rate. We obtained a Net Present Value of $67,000 and a Modified Internal Return Rate of 20% for the base scenario, which indicates the viability of the project. A Monte Carlo simulation was run to assess the robustness of the project to variability of three parameters: labor cost, energy cost, and market price; with random and simultaneous variation, resulting in 95% probability of getting a Modified Internal Return Rate larger than the current interest rate (8%) and a low probability (2.8%) to be financially unviable. This production system is worthy of consideration as an option to reduce the fishing pressure on the tegogolo natural populations of the Catemaco Lake while satisfying the market demand.

Tofu industry dominates by small-scale business with traditional production methods. On the other hand, demand for tofu products is quite high, and it is needed to increase tofu production. This study discusses the making of hygiene tofu maker tools able to simplify the production process. Based on the results of interviews with three tofu home industries in Cikarang, Bekasi, 17 request attributes of making an assistive tool obtain. Based on this, four technical responses were collected and will be developed become four concept designs. After conducting concept selection, it is determined to plan for making a tool which can simplify the process of making tofu. That is, starting from the manufacturing process, which starts from the pulp to the process of making tofu, can be put together into one manufacture of the tool. Thus, designing this tool can integrate the six stages of the tofu production process.

At the turn of the 19th – 20th century Siberia became a “melting pot” once again, where the representatives of various ethnic groups found themselves. The reasons for the resettlement beyond the Urals were of predominant economic character. The purpose of this paper is to analyze the impact of various social events of the first third of the 20th century on the life of Siberian Germans. Russian Germans engaged in agriculture were forced to seek the ways to survive inside Russia in the situation of the agrarian crisis. Modernization of the state migration policy at the beginning of the 20th century and development of the railway transport allowed for labor migration, as a result of which Siberia turned into one of the agrarian regions, being on the rise, by the mid-1910s. German immigrants, who created capitalist farm type households there and became a model for Russian old-timers and other immigrants, contributed greatly to his process. However, the events of 1914-1922 disrupted the customary pace of life in the German village. The economic policy of the Bolsheviks who came to power provoked famine in the first half of the 1920s.The German population suffered from hunger as well, which drove up emigration sentiments. However, NEP and restoration of cooperation allowed them to start rapid recovery of the small-scale economy. The All-Russian Mennonite Agricultural Union played a pivotal role in this process. The gradual curtailment of NEP and transition to a command-administrative economic model were connected with pressure on the German population among which the conservative-clerical sentiments prevailed. It was sure to provoke a new round of confrontation between the Russian Germans and the Soviet state in the late 1920s already. The article is intended for those interested in the history of ethnic minorities (Russian Germans) and national politics in the twentieth century.

Existing research has consistently shown that perceptions of the potential economic consequences of Scottish independence are vital to levels of support for constitutional change. This paper attempts to investigate the mechanism by which expectations of the economic consequences of independence are formed. A hypothesised causal micro-level mechanism is tested that relates constitutional preferences to the existing skill investments of the individual. Evidence is presented that larger skill investments are associated with a greater likelihood of perceiving economic threats from independence. Additionally, greater perceived threat results in lower support for independence. The impact of uncertainty on both positive and negative economic expectations is also examined. While uncertainty has little effect on negative expectations, it significantly reduces the likelihood of those with positive expectations supporting independence. Overall, it appears that a general economy-wide threat is most significant, and it is conjectured that this stems a lack of information on macroeconomic governance credentials.
