Contributions of Agroforestry Systems to Food Provisioning of Peasant Households: Conflicts and Synergies in Chiapas, Mexico

Traditional agroforestry systems are widely recognized for their contributions to provisioning, support, regulation, and cultural services. However, because of the advancement of industrial agriculture and a corporative food system, peasants' food systems are rapidly undergoing transformation. We identify the contributions of four types of agroforestry systems (AFS)—shade cocoa agroforest, shade coffee agroforest, milpas and homegardens—to food provisioning in peasant families and discuss conflicts between traditional food systems and the contemporary industrial model of production and consumption confronted by peasants and semi-proletarian migrants. We carried out research in 17 peasant communities in Chiapas, Mexico, and conducted 97 semi-structured interviews and agroecological inventories with peasant families, and 15 interviews with semi-proletarian families laboring in shade-grown coffee plantations. Thirty-nine weekly food diaries were applied in two communities. We recorded 108 plant species belonging to 49 botanic families. These species play an important role as sources of carbohydrates, protein, vitamins, minerals, and fatty acids. Despite the extraordinary agrobiodiversity of peasant agroecosystems, peasant families (PF) are changing their AFS' structure, composition and functions due to the influence of agribusiness, global markets, and public policies that orient changes in production and marketing, which in turn devalue local food, agrobiodiversity, and knowledge. Changing perceptions regarding the value of “good food” vs. “food of the poor” and competition over land use between traditional and modern systems are driving changes in diet, food sources, and health of PF who are including industrialized foods in their diets, driving changes in consumption patterns and affecting human health. For semi-proletarian migrants laboring in coffee plantations, land access in and outside of the plantation and strengthening social networks could mean access to healthier and culturally appropriate foods. While peasants have historically responded to market and household needs, articulating both activities to satisfy family needs and provide income is limited. This work highlights the urgent need to acknowledge the non-monetary value of local foods, agrobiodiversity, local knowledge, community building, and the need to work towards securing land access for landless workers in Latin America.

Consistency of attack level of coffee berry borer (Hypotenemus hampei Ferr.) on organic and conventional arabica coffee plantation in Aceh Tengah District, Aceh Province, Indonesia

A study has been conducted for 3 consecutive years since 2019 to 2021 to investigate the influence of cultivation system of Arabica coffee against the attack of the coffee berry borer (Hypothenemus hampei Ferr.) in Arabica coffee plantations in Aceh Tengah District, Aceh Province, Indonesia. We observed the attack level of H. hampei on Arabica coffee plants that were cultivated both organically and conventionally. The results showed that for three years observation, in general, the attack level of coffee berry borer (CBB) on organic and conventional coffee plantations was not significantly different. Observations in 2019 showed that the attack level of CBB on organic coffee plantations ranged from 27-34 % and on conventional coffee plantations ranging from 33-49 %. Observations in 2020 showed that the attack rate of CBB on organic and conventional coffee ranged from 20-40 % and 28-41%, respectively, while observations in 2021 were 25-26 % and 27-28 %. The results of these studies indicate that the level of CBB attack on organic coffee plantations is no different from conventional coffee plantations that routinely use synthetic pesticides. This indicates that in organic coffee plantations, natural enemies have played an important role in suppressing the development of CBB populations. Although the use of synthetic pesticides in conventional coffee plantations can suppress pest populations, it is suspected that these pesticides also play a role in reducing the population of natural enemies of pests. Therefore, organic coffee cultivation is much more profitable, especially it can reduce the cost of buying synthetic pesticides and fertilizers, besides ensuring the safety of coffee farmers, workers, and consumers from harmful chemical contamination from pesticides.

Soil Moisture Assessment Using Soil Moisture Index (SMI) Method at the Bangelan Coffee Plantation, Malang Regency, East Java

Water is one of the limiting factors in the growth of coffee plants. If plants experience a lack of water, it can inhibit plant growth and, at a critical level, can lead to drought stress and plant damages. The available soil water to plants can be estimated from the level of soil moisture index. The monitoring of soil moisture status can be used in improving the management of coffee plantations. Soil Moisture Index (SMI) is a method that can be used to estimate the level of soil moisture using remote sensing technology using NDVI and LST values. The purpose of this study was to analyze the status and distribution of soil moisture at the coffee plantation; analyze the relationship between vegetation index and soil moisture; and analyzed the relationship between soil moisture status using the SMI method and soil moisture measured in coffee plantations. Results showed that the soil moisture index obtained from Landsat 8 OLI/TIRS image processing had an average value of 0.60. The average soil moisture index at the study site is 1.05. Soil moisture index from the Landsat 8 OLI/TIRS image has a significant positive effect on soil moisture at the study site (y = 7.4996x – 3.4789; R2 = 0.7146**). It is suggested that the SMI method can be used to estimate soil moisture in the coffee plantation.

Characterization and assessment of water quality in mountainous sub-basins on the Manhuaçu River, MG

The objective of this chapter is to carry out an analysis of the water quality of six different sites in the Manhuaçu River basin and to propose measures for the saved sites. Changes in land cover occur and can cause degradation of the landscape. Hydrographic data selected by IBGE and IEDE level curves on a scale of 1: 50,000 were used and performed on MDEHC using Arc GIS software. Six different locations were collected in the field in the Manhuaçu River basin in February 2019. The records provided by SAAE Manhuaçu were also used. How the analyzes were evaluated and using a Water Quality Index (IQA) for the saved locations. As sub-basins Córrego Bom Jesus, Rio Manhuaçu and Rio São Luis lowered low values of dissolved oxygen with values of 0.0; 2.3 and 2.5 mg l-1, respectively. Córrego Bom Jesus had the lowest IQA value, followed by Rio Manhuaçu and Rio São Luis with values of 36.69; 44.92 and 47.84 values considered ruins. High levels of pesticides were not detected in surface waters. The product of coffee plantations close to water courses and a potential contamination by pesticides are of concern, and it is necessary to increase a protected area in the riparian zone.

Does Shade Impact Coffee Yield, Tree Trunk, and Soil Moisture on Coffea canephora Plantations in Mondulkiri, Cambodia?

Shade is a natural condition for coffee plants; however, unshaded plantations currently predominate in Asia. The benefits of shading increase as the environment becomes less favorable for coffee cultivation, e.g., because of climate change. It is necessary to determine the effects of shade on the yield of Coffea canephora and on the soil water availability. Therefore, three coffee plantations (of 3, 6, and 9 ha) in the province of Mondulkiri, Cambodia, were selected to evaluate the effect of shade on Coffea canephora yields, coffee bush trunk changes, and soil moisture. Our study shows that shade-grown coffee delivers the same yields as coffee that is grown without shading in terms of coffee bean weight or size (comparing average values and bean variability), the total weight of coffee fruits per coffee shrub and the total weight of 100 fruits (fresh and dry). Additionally, fruit ripeness was not influenced by shade in terms of variability nor in terms of a possible delay in ripening. There was no difference in the coffee stem diameter changes between shaded and sunny sites, although the soil moisture was shown to be higher throughout the shaded sites.

Nitrous Oxide Emission Fluxes in Coffee Plantations during Fertilization: A Case Study in Costa Rica

The main source of N2O emissions is agriculture, and coffee monocultures have become an important part of these emissions. The demand for coffee has increased in the last five decades. Thus, its production in agricultural fields and the excess of fertilizers have increased. This study quantified N2O emissions from different dose applications and types of nitrogen fertilizer in a region of major coffee production in Costa Rica. A specific methodology to measure N2O fluxes from coffee plants was developed using Fourier-transform infrared spectroscopy (FTIR). Measurements were performed in a botanical garden in Germany and plots in Costa Rica, analyzing the behavior of a fertilizer in two varieties of coffee (Catuai and Geisha), and in a field experiment, testing two types of fertilizers (chemical (F1) and physical mixture (F2)) and compost (SA). As a result, the additions of synthetic fertilizer increased the N2O fluxes. F2 showed higher emissions than F1 by up to 90% in the field experiment, and an increase in general emissions occurred after a rain event in the coffee plantation. The weak levels of N2O emissions were caused by a rainfall deficit, maintaining low water content in the soil. Robust research is suggested for the inventories.

Weather based forewarning models for coffee berry borer and shot hole borer in Wayanad, Kerala

Pest damage due to coffee berry borer and shot hole borer in coffee plantations in Regional Coffee Research Station, Chundale and data on weather parameters were recorded during 1977 to 2007 (30 years). These long- term data on the pest damage and weather parameters were utilized to study the influence of weather variables on coffee berry and shot hole borer incidence with a view to develop weather based forewarning models for coffee berry borer and shot hole borer damage in Wayanad. The damage of coffee berry borer (CBB) was observed to be significant during January to March while the damage of shot hole borer (SHB) was spread during January to April and October to December. Highest percent damage of coffee berry borer and shot hole borer was observed during first fortnight of January. Maximum damage due to coffee berry borer was observed during 1982 and maximum damage due to shot hole borer was observed in 1994. Maximum temperature recorded during the first fortnight of January is predominant weather variable determining infestation of shot hole borer during first fortnight of January. Harvest and budding stages of the crop suffered heavy incidence of coffee berry borer and shot hole borer, respectively.

The Theatre of the Senses: Introductory Words and a Short Conversation for the Symposium

What happens to us when we enter a Teatro de los Sentidos (Theatre of the Senses) experience? Why do we need to play? Where does our need to play come from? Why is sensory theatre relevant today? For what strange reasons do humans like to play getting lost and finding themselves in the dark? I want to share with you the reasons why Teatro de los Sentidos has been significant to me ever since I became aware of inventing myself and inventing it in my childhood games, imagining forbidden labyrinths in Colombian coffee plantations, until today, at my eighty years of age. It is clear that a lot of primal and parallel knowledge has developed over time in all cultures. Myths, celebrations, imagination, poetry, symbolic powers ... resonate differently, each according to historical circumstances. Let us ask ourselves together: what potential does sensorial theatre have today? (Enrique Vargas: Some questions before the symposium.)

COFFEE TOURISM DEVELOPMENT STRATEGY BASED ON LOCAL CULTURE AS AN EFFORT TO INCREASE INCOME DURING THE COVID 19 PANDEMIC IN ACEH CENTRAL REGENCY

There are so many potential of Gayo highlands tourism, Central Aceh Regency, both natural tourism and cultural tourism. Based on initial observations from data from the Department of Culture, Tourism, Youth and Sports of Central Aceh Regency in 2018 with a total of 38 natural and artificial tourist objects, besides that the Gayo community has customs, culture and traditions that can become one of the cultural tourism destinations, as well as the potential for coffee plantations. For this reason, a more systematic study of tourism development management is needed by combining elements of existing physical and non-physical potential in order to increase the level of community income through the potential arising from tourism activities. The purpose of this study is to further examine the strategy of developing coffee tourism, both in the form of physical elements and non-physical elements through existing local wisdom as an effort to increase income, especially during the Covid19 Pandemic Period in Central Aceh Regency. The research method is descriptive qualitative with a sample of 40 respondents from coffee entrepreneurs and coffee shops in several tourist attraction areas. The results showed that Central Aceh Regency has great potential for the development of a coffee tourism model based on local culture in order to increase people's income, especially people who are directly involved in tourism management and coffee farmers.
