Effects of Fair Trade and organic certifications on small-scale coffee farmer households in Central America and Mexico

We provide a review of sustainable coffee certifications and results from a quantitative analysis of the effects of Fair Trade, organic and combined Fair Trade/organic certifications on the livelihood strategies of 469 households and 18 cooperatives of Central America and Mexico. Certified households were also compared with a non-certified group in each country. To analyze the differences in coffee price, volume, gross revenue and education between certifications, we used the Kruskal‐ Wallis (K‐W) non-parametric test and the Mann‐Whitney U non-parametric test as a post-hoc procedure. Household savings, credit, food security and incidence of migration were analyzed through Pearson’s chi-square test. Our study corroborated the conditions of economic poverty among small-scale coffee farmer households in Central America and Mexico. All certifications provided a higher price per pound and higher gross coffee revenue than non-certified coffee. However, the average volumes of coffee sold by individual households were low, and many certified farmers did not sell their entire production at certified prices. Certifications did not have a discernable effect on other livelihood-related variables, such as education, and incidence of migration at the household level, although they had a positive influence on savings and credit. Sales to certified markets offer farmers and cooperatives better prices, but the contribution derived from these premiums has limited effects on household livelihoods. This demonstrates that certifications will not singlehandedly bring significant poverty alleviation to most coffee-farming families. Although certified coffee markets alone will not resolve the livelihood challenges faced by smallholder households, they could still contribute to broad-based sustainable livelihoods, rural development and conservation processes in coffee regions. This can be done by developing more active partnerships between farmers, cooperatives, certifications and environmental and rural development organizations and researchers in coffee regions. Certifications, especially Fair Trade/organic, have proven effective in supporting capacity building and in serving as networks that leverage global development funding for small-scale coffee-producing households.

Agroecology as a Transdisciplinary, Participatory, and Action-Oriented Approach

This article traces multiple directions in the evolution of agroecology, from its early emphasis on ecological processes in agricultural systems, to its emergence as a multidimensional approach focusing on broader agro-food systems. This review is timely, as agroecology is being increasingly applied within a diversity of scientific-, policy-, and farmer-based initiatives. We contrast different agroecological perspectives or “agroecologies” and discuss the characteristics of an agroecology characterized by a transdisciplinary, participatory and action-oriented approach. Our final discussion describes the contents of the special issue, and states our goal for this compilation, which is to encourage future work that embraces an agroecological approach grounded in transdisciplinarity, participation, and transformative action.

Agrobiodiversity and Shade Coffee Smallholder Livelihoods: A Review and Synthesis of Ten Years of Research in Central America

We used households as the primary unit of analysis to synthesize agrobiodiversity research in small-scale coffee farms and cooperatives of Nicaragua and El Salvador. Surveys, focus groups, and plant inventories were used to analyze agrobiodiversity and its contribution to livelihoods. Households managed high levels of agrobiodiversity, including 100 shade tree and epiphyte species, food crops, and medicinals. Small farms contained higher levels of agrobiodiversity than larger, collectively managed cooperatives. Households benefited from agrobiodiversity through consumption and sales. To better support agrobiodiversity conservation, our analysis calls for a hybrid approach integrating bottom-up initiatives with the resources from top-down projects.

Food sovereignty: an alternative paradigm for poverty reduction and biodiversity conservation in Latin America

Strong feedback between global biodiversity loss and persistent, extreme rural poverty are major challenges in the face of concurrent food, energy, and environmental crises. This paper examines the role of industrial agricultural intensification and market integration as exogenous socio-ecological drivers of biodiversity loss and poverty traps in Latin America. We then analyze the potential of a food sovereignty framework, based on protecting the viability of a diverse agroecological matrix while supporting rural livelihoods and global food production. We review several successful examples of this approach, including ecological land reform in Brazil, agroforestry, milpa, and the uses of wild varieties in smallholder systems in Mexico and Central America. We highlight emergent research directions that will be necessary to assess the potential of the food sovereignty model to promote both biodiversity conservation and poverty reduction.

Cooperative management and its effects on shade tree diversity, soil properties and ecosystem services of coffee plantations in western El Salvador

We compared how management approaches affected shade tree diversity, soil properties, and provisioning and carbon sequestration ecosystem services in three shade coffee cooperatives. Collectively managed cooperatives utilized less diverse shade, and pruned coffee and shade trees more intensively, than individual farms. Soil properties showed significant differences among the cooperatives, with the following properties contributing to differentiation: N, pH, P, K, and Ca. Higher tree richness was associated with higher soil pH, CEC, Ca, and Mg, and lower K. Higher tree densities were associated with lower N, K, and organic matter. Although we found differences in the incidence of provisioning services (e.g., fruit), all plantations generated products other than coffee. No differences were observed between C-stocks. The history and institutional arrangements of cooperatives can influence management approaches, which affect ecosystem properties and services. Our study corroborates that interdisciplinary investigations are essential to understand the socio-ecological context of tropical shade coffee landscapes.

Agroecology and Alternative Agri-Food Movements in the United States: Toward a Sustainable Agri-Food System

The concept of agroecology in the United States is born out of a dialectical process of co-production of knowledge whereby the science of agroecology has shaped and been shaped by alternative agri-food movements, policy, and local practice. This article examines the relationship between agroecology and alternative agri-food movements and identifies opportunities for greater engagement. The article concludes with a discussion of the challenges and opportunities to scaling up agroecology and sustainable agri-food systems.

Extent, pattern, and multifunctionality of treed habitats on farms in Vermont, USA

Agroecosystems can serve as multifunctional landscapes when treed habitats such as woodlots, hedgerows, riparian buffers, windbreaks, and orchards, are conserved on farms. We investigated the extent, pattern, and multifunctionality of on-farm treed habitats for 16 Vermont farms in the Lamoille watershed of the Lake Champlain Basin. The site was selected because the land use pattern is representative of the region, containing a mixture of agriculture and forest in different habitat types. We used a GIS-based approach to delineate treed habitats on farms and conducted semi-structured interviews with farmers to explore their perception of the functions of treed habitats. Through an evaluation of the relationship between farm characteristics and spatial attributes of treed habitats, we found farm size to be an important variable. Larger farms had more land in treed habitats, while the pattern of these habitats was more complex on smaller farms. Average elevation of the farm, an indicator of biophysical conditions, was a stronger predictor of the extent of treed habitats than farm characteristics. From interviews, we found that farmers benefited from alternative forest products, both for direct consumption and sale, including firewood, timber, maple sugar, edible fruits and nuts, and wood crafts. Most farmers also recognized cultural and ecological functions provided by treed habitats. These results have implications for developing policies to promote the conservation of treed habitats, considering the preferences of the landowner or farmer.

‘Los meses flacos’: seasonal food insecurity in a Salvadoran organic coffee cooperative

Central American coffee farmers commonly refer to annual periods of food insecurity as ‘los meses flacos’ – the thin months – indicating a recurring season in which they are unable to meet household food needs. Although this is a common phenomenon, little empirical research has documented the seasonal food insecurity that many small-scale coffee farmers face. Household surveys and focus groups were conducted with 29 members of an organic coffee cooperative in western El Salvador to determine the causes of, and responses to, seasonal food insecurity. Ninety-seven percent of households faced food shortages during some period of the year. The two most common proximate causes of food shortages were lack of income-generating opportunities to buy food and running out of staple food crops. Families coped with seasonal food shortages by borrowing money and food, seeking work outside of the community, changing diet, and selling livestock. It is clear that small-scale coffee farmers seek to maintain a balance between coffee, which provides income, and food crops, which provide staple food. Livelihood and income diversification are important coping strategies that should be supported; however, we conclude that efforts to address food insecurity in coffee regions require deeper structural changes to support peasant farmers.

Interactions between Carbon Sequestration and Shade Tree Diversity in a Smallholder Coffee Cooperative in El Salvador

Agroforestry systems have substantial potential to conserve native biodiversity and provide ecosystem services. In particular, agroforestry systems have the potential to conserve native tree diversity and sequester carbon for climate change mitigation. However, little research has been conducted on the temporal stability of species diversity and aboveground carbon stocks in these systems or the relation between species diversity and aboveground carbon sequestration. We measured changes in shade-tree diversity and shade-tree carbon stocks in 14 plots of a 35-ha coffee cooperative over 9 years and analyzed relations between species diversity and carbon sequestration. Carbon sequestration was positively correlated with initial species richness of shade trees. Species diversity of shade trees did not change significantly over the study period, but carbon stocks increased due to tree growth. Our results show a potential for carbon sequestration and long-term biodiversity conservation in smallholder coffee agroforestry systems and illustrate the opportunity for synergies between biodiversity conservation and climate change mitigation.

Transition from Semi-Confinement to Pasture-Based Dairy in Brazil: Farmers’ View of Economic and Environmental Performances

The production of ecosystem goods and services has increased significantly in the last 100 years, while the capacity of ecosystems to generate supporting and regulating services has decreased. In this context, agriculture and livestock production have become major concerns. At the same time, livestock, particularly dairy cows, play a key role and can serve to improve ecosystems, production, and rural livelihoods. We randomly selected and conducted semistructural interviews with 61 dairy family farmers from four cooperatives in the Encosta da Serra Geral Region of the Atlantic rainforest in Santa Catarina, Brazil. The goal was to analyze their production and viewpoints about environmental variables after adopting management-intensive grazing (MIG). The overall results showed that when farmers changed from semi-confinement and continuous grazing to MIG they perceived improvements in production, livelihoods, and ecosystem services. Moreover, according to farmers’ insights, MIG could be a tool to increase water and soil quality, animal health, alleviate poverty, and complement Brazilian conservation efforts.
