We use the three principles of Climate Smart Agriculture (CSA) as an analytical framework. We carry out surveys and measurements in the field, evaluating three principles, 10 criteria and 12 indicators. We found that the application of<br />agroecological practices improves food self-sufficiency and family income and reduces antagonisms or increases synergies between productivity and adaptation or mitigation. This suggests that agroecology can help achieve simultaneously the often-conflicting goals of Climate Smart Agriculture.</p> Yésica Quispe Conde Bruno Locatelli Améline Vallet Raúl Blas Sevillano Copyright (c) 2022 YÉSICA QUISPE CONDE 2022-06-22 2022-06-22 22 1 5 29 10.7201/earn.2022.01.01 Farm size and productivity in Nicaragua: Parametric and nonparametric analyses for panel data <p>This paper examines the inverse relationship hypothesis (IR-H) between farm size and agricultural productivity in Nicaragua using parametric and nonparametric methods designed specifically for panel data. The data employed are from the World Bank’s Living Standards Measurement Study for the years 1998, 2001 and 2005. The analysis reveals strong support for the IR-H based on a number of alternative parametric specifications. The results from the nonparametric models lend partial support to the IR-H,<br />and such support is weaker than what is obtained from the parametric models, particularly among medium and large landholders.</p> Alexandre Nunes Almeida Boris E.

The objective of this article is to explore the productive, commercial and management strategies of small-scale vegetable growers at the SMR, their attitudes towards their activity, and to identify different profiles. We surveyed in person 170 farmers. The data was analyzed using descriptive and multivariate techniques. Results suggest<br />that different characteristics and strategies are concomitant to certain attitudes that vegetable growers hold towards key aspects such as innovation or willingness to associate.</p> Sofía Boza Marcos Mora Aracely Nuñez Macarena Espinoza Karina Orellana Copyright (c) 2022 Sofía Boza, Marcos Mora, Aracely Nuñez, Macarena Espinoza, Karina Orellana 2022-06-22 2022-06-22 22 1 53 67 10.7201/earn.2022.01.03 Rangeland cattle production in Uruguay: Single-output versus multi-output efficiency measures <p><span lang="EN-US">Rangeland cattle production is the largest agricultural sector of Uruguay. Ranches produce up to three products (beef, sheep-meat, and wool) usually combined into an equivalent meat (EM) index. The objective is to compare the empirical results from the estimation of a single output stochastic production frontier (SPF) and a multi-output stochastic ray frontier (SRF) to provide insights on the use<br />of the EM index to evaluate ranches performance. Results show similar efficiency scores. The average level of TE is 0.769 for the SPF and 0.779 for the SRF. We cannot discard EM index as a simple measure of combined production.</span></p> Federico García-Suárez Gabriela Pérez-Quesada Carlos Molina Riccetto Copyright (c) 2022 Federico García-Suárez, Gabriela Pérez-Quesada, Carlos Molina Riccetto 2022-06-22 2022-06-22 22 1 69 88 10.7201/earn.2022.01.04 Family Agrarian Neuroeconomics: Application of the Hierarchy of Emotional Neural Patterns in the Alpaca Fiber Sector and Native Potatoes in Peru <p>This study aims to analyze the neuroeconomic decision-making of small producers of alpaca fiber and native potato considering the Neural Pattern Hierarchy Theory and the Temporal Memory Model. The aim is to measure the impact on the correlation level of holistic competencies of innovation in The learning process based on entrepreneurship. To achieve this, experimental, transactional, correlational, and descriptive research was conducted with a sample of 88 individuals. A methodology for aligning emotional neural patterns was applied. The results show that (H1:Y0 &gt; Y1) emphasizing alpaca fiber.</p> Isaac Zúñiga Aguilar Antonio Colom Gorgues Eduard Cristóbal Fransi Copyright (c) 2022 Isaac Zúñiga Aguilar, Antonio Colom Gorgues, Eduard Cristóbal Fransi 2022-06-22 2022-06-22 22 1 89 121 10.7201/earn.2022.01.05 The volatility of the prices of bean (Phaseolus vulgaris) in Mexico: 2000-2020 <p>The objective is to evaluate whether bean prices present volatility clustering effects and whether these have implications for the food security of the population. Symmetric and asymmetric models belonging to the ARCH family were used. They were applied to three bean varieties for eight Mexican markets. The results showed a high persistence of volatility in pinto and black beans, the persistence is bigger in local markets than in those with different point of origin and destination. The volatility of the three varieties impacts on the consumption decisions of the most disadvantaged population. </p> María del Rosario Granados Sánchez Luis Gómez Oliver Javier Galán Figueroa Copyright (c) 2022 María del Rosario Granados Sánchez, Luis Gómez Oliver, Javier Galán Figueroa 2022-06-22 2022-06-22 22 1 123 148 10.7201/earn.2022.01.06
