Environmentally induced farmer migration is an important livelihood strategy, yet little is known of the effects on the destination region agroecosystem information networks and management practices. In the forest-savanna transition zone (Brong Ahafo Region) of Ghana, where migration from northern regions (migrant) and from neighboring regions (settler) is active, we chart the role of migrant famers and the type of agroecosystem management practices embedded in information networks using a social networks approach. Based on empirical network data from 44 respondents across three communities, we illustrate a diffuse information network, with variable tie frequency between settlement categories (local, settler, or migrant) of farmers. The cohesion of this...

Diversified Farming Systems: An Agroecological, Systems-based Alternative to Modern Industrial Agriculture

Kremen, Claire; Department of Environmental Sciences, Policy and Management, University of California Berkeley; ckremen@berkeley.edu; Iles, Alastair; Department of Environmental Sciences, Policy and Management, University of California Berkeley; iles@berkeley.edu; Bacon, Christopher ; Department of Environmental Studies and Sciences, Santa Clara University; christophermbacon@gmail.com.

This Special Issue on Diversified Farming Systems is motivated by a desire to understand how agriculture designed according to whole systems, agroecological principles can contribute to creating a more sustainable, socially just, and secure global food system. We first define Diversified Farming Systems (DFS) as farming practices and landscapes that intentionally include functional biodiversity at multiple spatial and/or temporal scales in order to maintain ecosystem services that provide critical inputs to agriculture, such as soil fertility, pest and disease control, water use efficiency, and pollination. We explore to what extent DFS overlap or are differentiated from existing concepts such as sustainable, multifunctional, organic or ecoagriculture....

Optimizing nitrogen rates in the midwestern United States for maximum ecosystem value

Ewing, Patrick M; University of Minnesota, Department of Agronomy and Plant Genetics ; ewing069@umn.edu; Runck, Bryan C; University of Minnesota, Department of Geography, Environment and Society; runck014@umn.edu.

The importance of corn production to the midwestern United States cannot be overestimated. However, high production requires high nitrogen fertilization, which carries costs to environmental services such as water quality. Therefore, a trade-off exists between the production of corn yield and water quality. We used the Groundwater Vulnerability Assessment for Shallow depths and Crop Environment Resource Synthesis-Maize models to investigate the nature of this trade-off while testing the Simple Analytic Framework trade-offs featured in this Special Feature. First, we estimated the current levels of yield and water quality production in northeastern Iowa and southern Minnesota at the 1-square-kilometer, county, and regional scales. We then constructed an...

Rural Social Movements and Agroecology: Context, Theory, and Process

Rosset, Peter M; Center for the Study of Rural Change in Mexico (CECCAM); University of Michigan at Ann Arbor; rosset@globalalternatives.org.

Rural social movements have in recent years adopted agroecology and diversified farming systems as part of their discourse and practice. Here, we situate this phenomenon in the evolving context of rural spaces that are increasingly disputed between agribusiness, together with other corporate land-grabbers, and peasants and their organizations and movements. We use the theoretical frameworks of disputed material and immaterial territories and of re-peasantization to explain the increased emphasis on agroecology by movements in this context. We provide examples from the farmer-to-farmer movement to show the advantages that social movements bring to the table in taking agroecology to scale and discuss the growing agroecology networking process in the...

Agroecological knowledge construction in the semi-arid region of Ceará

ExtensaoRural

Pinheiro, Bruna Carolina Frazão Silva; Gamarra-Rojas, Guillermo; Mattos, Jorge Luiz Schirmer de; Lima, Filipe Augusto Xavier; Fernandes, Luis Eduardo Sobral.

The National Policy for Technical Assistance and Rural Extension (PNATER) represents the resumption of strengthening family farming and meeting society's demands for sustainable agriculture. Its materialization translates into the transition from conventional agriculture to ecologically based agriculture, based on participatory methodologies and under a multidisciplinary and systemic approach toRural Extension. The article presents an analysis of the perceptions of the social actors of organic and agroecological agriculture in the semi-arid region of Ceará on the process of building agroecological knowledge. To this end, we performed a content analysis of interviews, using the Ecological Knowledge System (SCE) and the objectives of PNATER as benchmarks....

This study aims to evaluate the economic viability of supplying sweet potato meal as an alternative to the use of corn meal in the composition of laying hens feed in an agroecological system. Therefore, a field experiment was conducted in a family property in Jandaia do Sul - PR, with comparative analysis of two feeding compositions for laying hens in agroecological systems. The data were collected between March and July 2019, using methodological tools in two phases, with production cost data collection and economic feasibility analysis through gross and net margins and indicators such as the benefit index cost 2 | Análise da viabilidade econômica no uso de farelo de batata-doce na ração de poedeiras agroecológica and through a counterfactual test of two...

This article deals with the relationship between family farming, ethical-cultural values, solidarity, agroecological practice and good living. Initially, a reflection on the possible impacts of capitalist development on the category of family farmers is presented. After that, the existing relationship between solidarity economy and family agriculture is approached and, in the sequence, solidarity and agroecological family production style are correlated with the objective of living well. In this sense, as an example, the case of two cooperatives of ecological family farmers is presented. In the final conclusions, the effective possibilities of non-alienated and solidary work, experienced by ecological family farmers, are highlighted as a factor in the...

ABSTRACT The experiment was conducted in (Integrated Agroecological Production System in Seropedica-RJ) Sistema Integrado de Produção Agroecológica (SIPA), Seropédica-RJ, to evaluate the effect of two maize populations in relation to baby corn productivity and shoot mass, to determine the contribution of pre-cultivated maize, green velvet and organic topdressing fertilization in the agronomic performance of cabbage (Brassica oleracea var. capitata). The experimental design consisted of randomized blocks with three treatments (maize population of 100,000 and 200,000 plants ha-1 and green velvet at 100,000 plants ha-1) and eight replicates. After that, cabbage was transplanted in the straw of these species, adopting a randomized block design allocated in...

A Caatinga vem sendo utilizada desde tempos do pré-descobrimento como fonte de alimentos para a população humana, seja pela ação catadora de frutos e caçadora pelos indígenas, seja pela exploração agrícola, pastoril e madeireira, intensificadas a partir da colonização pelo homem branco. As características edafoclimáticas da Caatinga impõem severas restrições aos diversos tipos de exploração agrícola de base intensiva, privilégio possível, apenas para alguns setores, porém inviável na maior parte de seu território. Por sua vez, a Agroecologia tem referenciado os Sistemas Agroflorestais (SAFs) como um modelo de produção de alimentos fundamentados no funcionamento dos ecossistemas naturais. Neste contexto, os SAFs podem surgir a partir da interface entre...
