The objective of this research is to provide an understanding of how coffee production has been taking place since the coffee industry in Vietnam came out in the global market after Doi Moi. Current research tries to understand how the local households of coffee production adjusts to their production process according to internal and external influences. In order to explore coffee production in the level of local and household units, the structure of coffee production in Dak Lak is first explored in terms of production and sales with the cases from two communes. The examination reveals that general characteristics of coffee crops that would reflect coffee production structure. Further, this study interrogates farmers' response to reflect some direct and indirect influences in recent years. That shows how the elements of coffee production in global market induce a change of coffee production in the study area. Those aspects are analyzed in relation to yearly coffee price fluctuation and diversification. Also, this research explores some of farmers' responses toward the environmental friendly coffee production.

Effect of climate change on the agricultural sector has been predicted and studied, including its effects on coffee cultivation. Climate change can directly impact coffee production or indirectly influence it through its effects on coffee pests. In Indonesia, coffee is a critical export commodity. Climate change can have a large effect on many farmers if it is not addressed appropriately. This study summarizes several studies and data on how climate change affects coffee production and the coffee berry borer (CBB; Hypothenemus hampei) pest in Indonesia. Adaptation plans that can be employed to mitigate impacts of climate change are also summarized.

In this paper, the carbon resources recycling of the overview of coffee waste generation in Vietnam. Since few years, there has been a significant research studies was done in the areas of coffee waste generation areas and also waste water generation from coffee production. The coffee residue (solid) and waste water (liquid) both are caused the underground water contamination and also soil contamination. These residues contain high organic matter and acid content leads to the severe threat to environment. In second stage of coffee production process, the major solid residue was generated. Various solid residues such as spent coffee grounds, defective coffee beans and coffee husks) pose several environmental concerns and specific problems associated with each type of residue. Due to the unlimited usage of coffee, the waste generation is high. At the same time, some researchers have been investigated the spent coffee wastes are the valuable sources for various valuable compounds. Biodiesel or biomass productions from coffee waste residues are the best available utilization method for preventing the landfill problems of coffee waste residues.

Vietnam is the second-largest coffee exporter in the world. Most of the coffee areas are concentrated in Dak Lak-a province of commercial agricultural production, making up 32.4% of the total coffee area in Vietnam. At present, coffee is the main income source for the province, with coffee accounting for 85% and 40%(2010) of the export value of the province and of the country, respectively. Although the rapid development of Dak Lak's coffee production significantly benefits the province and its coffee planters socioeconomically, emerging urgent problems such as land dispute among ethic groups need to be addressed. This paper aims to examine how coffee-production development in Dak Lak has affected land mobility. In addition, we consider how these changes have affected the livelihoods of the Kinh-the majority ethnic group in Vietnam-as well as the ethnic minorities. As a result, it is pointed out that the coffee development in Dak Lak creates the individual ownership on land. This ownership is more and more fortified when the encroaching land of the Kinh immigrants happens impetuously defying the customary law of the ethnic minorities.

This article describes the application of discrete event simulation in a process industry (coffee manufacturing) as a daily production-scheduling tool. A large number of end products (around 300), sporadic demand, and limited shelf life of coffee (90 days) make it difficult to generate feasible production schedules manually. To solve this problem, an integrated system was developed incorporating discrete event simulation methodology into scheduling process. The integrated system is comprised of two components: a scheduling program and a simulation model. The scheduling program is used to generate daily schedules for roasting, grinding, and packing coffee. The simulation model uses the generated schedules to simulate the production of coffee and regenerates a modified production schedule. In this paper, each of the components will be described in detail, evaluated in terms of performance factors, and validated with a set of real production data. Although this article focuses on a specific system, we will share our experiences and Intuitions gained and encourage other process industries to develop simulation-based scheduling tools.

Since the late 1990s Vinacafe has gone through strategic changes in corporate governance and managements due to an increase in the introduction of coffee MNCs, a growth of global demands in sustainable coffee, aging coffee tree, and the deterioration of coffee production with climate changes in Vietnam. Vinacafe has attempted to cope with these kinds of changes through strategies for equitization. Therefore, the main aim of this paper is to identify strategies for enhancing the competitiveness of the Vietnamese coffee industry by investigating changes in corporate governance and processes of coffee production and distribution. The equitization of Vinacafe has led to the enhancement of coffee competitiveness in two perspectives. Firstly, as it has decentralized decision-making from headquarter, subsidiaries have become able to strength their competitiveness themselves by introducing new technologies, improving coffee quality, and encouraging the introduction of eco-friendly production methods through cooperative relationships with stakeholders involved in coffee production and distributions in Vietnam. Secondly, it has also enhanced competitiveness through the diversification and effectiveness of coffee managements by intensifying the flexibility of contract with coffee farmers and diversifying coffee sales and supply chains in Vietnam.

A series of coffee middlemen has come to be regarded as an exploitative force in the lives of small and poor coffee farmers, which is called 'coyote', controlling production, paying unfair prices for labor and goods, and participating in fraudulent practices to maximize their own profits. However, the reality of gains captured by coffee middlemen in the value chain might be exaggerated and even unfair. Therefore, the main aim of this paper is to reconsider the implication of coffee middlemen for the development of coffee value chain in Vietnam. It also attempts to identify their characteristics by investigating relations among coffee farmers, middlemen and processing/exporting firms. In terms of middlemen's margin in the coffee sub-sector, their margin is quite small when compared to other actors higher in the value chain. Rather, coffee middlemen in Vietnam have played a critical role as an intermediary of change in local economies. More specifically, coffee middlemen in Dak Lak has played a significant role as a market facilitator by stimulating the access of farmers to markets by providing buyers for farmers thanks to changes in institutional environment. Also, they have played a critical role as an agent of sustainable coffee production by encouraging sustainable coffee production in accordance with the demand of processing and exporting firms.

Production of biodegradable polymer polyhydroxyalkanoates (PHAs) from industrial wastes exhibits several advantages such as recycle of waste and the production of high valuable products. To this end, this study aimed at isolating from the sewage treatment plant a PHA producing bacterium capable of utilizing wastes generated from biodiesel and food industries. A Bacillus cereus strain capable of producing poly(3-hydroxybutyrate) [P(3HB)] was isolated, which was followed by confirmation of P(3HB) accumulation by gas-chromatographic analyses. Then, the effects of nutrient limitation on P(3HB) production by B. cereus was first examined. Cells cultured in a minimal medium under the limitation of nitrogen, potassium and sulfur suggested that nitrogen limitation allows the highest P(3HB) accumulation. Next, production of P(3HB) was examined from both waste of biodiesel production (crude glycerol) and waste from food industry (spent coffee grounds). Cells cultured in nitrogen-limited minimal medium supplemented crude glycerol and waste spent coffee grounds extract accumulated P(3HB) to the contents of 2.4% and 1.0% of DCW. This is the first report demonstrating the capability of B. cereus to produce P(3HB) from waste raw materials such as crude glycerol and spent coffee grounds.
