\u3000The test site was a bamboo grove plot (60 m elevation, north-facing slope) at the Fukuoka Prefectural Agricultural and Forestry Experiment Station, Research Center for Utilization of Resources, located in Yamamoto-cho, Kurume City, Fukuoka Prefecture. The plot was planted in 1995, and has been managed by cutting down bamboos and tailoring parent bamboos to achieve a density of 300 standing bamboos\/10a every year. The soil is a fine-grained normal brown forest soil.<\/p>\n\n\n\n

\u3000Table 3 shows the working hours required for fertilizer application. The labor-saving area applied 1.4 times as much fertilizer as the conventional area, and thus required 4.2 hours\/10a\/person, 1.3 times as long as the latter area. Although the amount of summer fertilizer applied in the conventional area was the same as that of the courtesy fertilizer, the summer fertilizer required 3.5 hours\/10a\/person, 1.1 times longer than the courtesy fertilizer, probably because the work efficiency was reduced due to the heat. Assuming that the labor-saving zone required 2.5 hours per 10a\/man per year less than the conventional zone, assuming that the labor for the application of the original fertilizer was the same in both test zones.<\/p>\n\n\n

\u3000Although there are some unverified aspects, the yield of bamboo shoots in this study exceeded the yield target of 1000 kg\/10a (Nonaka, 2003) corresponding to an annual nitrogen fertilizer application rate of 20 kg\/10a every year for three years, and the coefficient of variation of yield was 0.23 (labor-saving area) and 0.14 (conventional area), which was sufficiently low compared to the average of 0.38 in 87 areas in Fukuoka Prefecture, which was investigated by Tanizaki et al. (2024), and the coefficient of variation of yield was 0.23 (labor-saving area) and 0.14 (conventional area), which was sufficiently low compared to the average of 0.38 in 87 areas in Fukuoka Prefecture, suggesting that the twice-yearly labor-saving fertilization schedule did not have a negative impact on bamboo shoot production.<\/p>\n\n\n\n

\u3000Currently, in bamboo shoot production, smart agriculture is progressing with the development of a \"bamboo shoot digging assistant robot\" (Horiuchi et al., 2015), which is shaped like a brushcutter and has a rotating mulberry blade at its tip, and a detector that uses resonance-type electrodes to detect underground bamboo shoots (Iwamoto et al., 2022). While looking forward to the development of such technologies, we would like to promote \"work style reforms\" that can be done now, and support production areas so that they can be maintained.<\/p>\n\n\n\n

\u3000In this issue, I will present examples of economic exploitation by developed countries that have caused soil degradation and environmental destruction in the Global South. In each case, the environmental destruction was caused by the expropriation of labor and resources in the name of producing raw materials necessary for our daily lives.<\/p>\n\n\n\n

\u3000The oil palm, also called palm palm, produces palm oil from the pulp of the fruit and palm kernel oil from the seeds. The two are different products with different main components (Figure 1).<\/p>\n\n\n

\u3000Palm oil is not only inexpensive, but is also resistant to oxidation. For this reason, it is widely used in processed foods, snacks, fast foods, French fries, ice cream, chocolate, margarine, soap, detergents, cosmetics, and other products. However, in Japan, the labeling of food ingredients only mentions \"vegetable fats and oils. Therefore, it is difficult to be aware of the fact that we depend heavily on palm oil in our daily lives.<\/p>\n\n\n\n

\u3000However, few small-scale farmers were able to adapt to this technology, and in practice, intensive cultivation was carried out very inappropriately. As a result, the soil on the farms suffered from erosion, and the overused chemical fertilizers and pesticides flowed into the rivers, reducing the number of river fish. The river fish were a valuable source of protein for the local population. The residents were no longer able to consume that protein source and had to spend more money to obtain another source of protein. To make ends meet, they turned to illegal trade in wildlife, especially endangered species such as orangutans and tigers. Thus, the lives of the inhabitants have changed drastically (Saito, 2020).<\/p>\n\n\n\n

\u3000Yamashita (2001) points out that, in response to consumers' demand for inexpensive food, \"Just as each person has his or her own value, there is and must be a decent price for things. The cost reductions that make food inexpensive are achieved by externalizing the environmental impact of the cost reductions onto people and the natural environment somewhere far away.<\/p>\n\n\n\n
