“…The characteristics of "moderate shade" in this study were a shade tree cover of between 41 and 60%, a tree density of 200-250 trees per hectare, and three to six tree species. This is a higher level of shade than that identified as optimal by Cerda et al (2020) who working just in the Turrialba area found no evidence of shade contributing to pest and disease yield losses when below 35% shade cover (equivalent to our low shade). In terms of the classification used by Moguel and Toledo (1999) our "moderate shade" would correspond to the "commercial or traditional polyculture shade" but not meet the complexity of "rustic shade" nor be as simple as "shaded monoculture" systems.…”

Despite many years of research, there is still a lack of consensus as to the nature of the relationship between shade trees and agronomic intensification in coffee agroforestry systems. While some studies find unshaded intensively managed coffee is the most productive, other studies find no trade-off between shade characteristics and productivity. Our study of 179 farms from the main coffee growing regions of Costa Rica and Guatemala analyzed how shade affected the productive response of coffee to intensification of agronomic management. Four levels of coffee productivity were differentiated for each country associated with three levels of shade development in Costa Rica and two levels in Guatemala. The highest coffee productivity group was associated with medium shade development in both countries. High shade groups had low productivity, but very low productivity groups were associated with low (Costa Rica) or medium (Guatemala) shade. Medium and high productivity farms were associated with high elevation, lower rainfall and regions with higher coffee prices. Yields with a moderate level of investment (720–1,500 USD−1) and with medium shade (LAI 0.55-1.1) were not significantly different from yields with higher investment or lower shade levels. The increase in yields with increasing N fertilizer application were similar under low, medium and high LAI, but the mean productivity significantly lower with high LAI. Agronomic intensification to increase productivity is equally effective for low and medium shade systems (LAI <1.1); low productivity farms may have high shade or low shade but are mainly limited by low investment. Intensification of production is compatible with medium shade levels that should deliver broader ecosystem services but achieving this depends on coffee prices enabling this investment.

“…The adaptive qualities of agroforestry have been extensively studied in the specialized field of climate change adaptation 2 (Nair, 1997;Akamani, 2016;Gomes et al, 2020). In particular, research has shown the potential of coffee agroforestry systems (CAFS) to reduce the impact of pests and diseases (Cerda et al, 2020) and to preserve soil carbon and biodiversity (Soto-Pinto et al, 2002;Baca et al, 2014;Läderach et al, 2017). The CAFS have been subjected to different adaptation approaches, especially ecosystem-based adaptation (Nalau and Becken, 2018) and community-based adaptation (c.f.…”

“…There is an ongoing process of landscape simplification and homogenization seeking to achieve higher productivity. The implications of this in terms of adaptation are clear: the way in which the new varieties are being introduced does little to strengthen the adaptive properties of the agroforestry systems (Cerda et al, 2020).…”

The most recent wave of coffee leaf rust, and its interaction with climatic variability, caused severe crop losses in shade-grown coffee areas in Latin America during the 2010–14 production cycles and beyond. Fungal attack on traditional Arabica varieties led to a process of substitution with new coffee varieties that are tolerant or resistant to the pathogen. The adaptation literature classifies this type of intervention as an incremental adaptation, with the potential to lead the system toward sustainable transformation. This research explores the initial consequences of introducing certain hybrid varieties into the transboundary area of the Tacaná Volcano, located between Chiapas and Guatemala, with the objective of identifying aspects that put the potential for adaptive agroforestry at risk. We hypothesize that the interaction of a range of economic, political, and ecological factors leads to ambiguous results in terms of both production and environmental adaptation. Ecological and management variables were analyzed in a case study of 30 producers. Quantitative data, collected through ecological plot sampling and application of a socio-productive survey, was complemented with ethnographic data. We conclude that, for our case study, the manner in which these new coffee varieties were introduced raises new sources of vulnerability that could be compromising the local and ecological benefits of agroforestry systems, as well as diminishing their capacity to cope with the future impacts of climate change.

“…The low level of selfprovisioning in Coffee Farmers' households is probably because most of the farm's productive area is devoted to coffee cultivation (Salcedo 2016). But coffee and cocoa have been established crops under agroforestry systems that allow for increased diversity of food species (Vaast and Somarriba 2014), mostly fruits (Cerda et al 2020;Cerda et al 2014). Crops in agroforestry systems and fruit trees grown in the home garden explain the higher percentage of self-provisioning food in the seven types of rural households.…”

Production for self-provisioning contributes to food security in rural territories; however, studies have indicated that this capacity is limited. We analyze the impact of livelihood strategies on self-provisioning conditions in 162 rural households in the department of Huila, Colombia. Different topics were examined: a. source of the food; b. composition of home gardens; c. push and pull factors towards self-provisioning; d. capacity of rural households to access food in the face of COVID-19. Results indicated that rural households are 75% dependent on grocery stores for access their food. Only 51% of households have a home garden, with limited species diversity. Capacity for self-provisioning varies according to the livelihood strategies and capital endowment of the household; those with a greater diversity of agricultural activities have better capacity to provide for self-provisioning. We conclude that resilience of rural households is minimal to face atypical events such as the pandemic generated by COVID-19.
