Los “márgenes multifuncionales” son franjas de terreno con vegetación espontánea o sembrada implantados en los márgenes de las parcelas, para mejorar la biodiversidad. Esta práctica se incluye en una medida agroambiental destinada a cultivos herbáceos de secano en Andalucía, y es compatible con los futuros eco-regímenes. Para valorar la disposición de los agricultores andaluces a realizar esta práctica, se aplica un modelo de valoración contingente doble dicotómica, realizado a partir de una encuesta telefónica. La disposición a aceptar de los agricultores obtenida supera el importe previsto en la medida actual, lo que tiene implicaciones para el diseño de políticas.

Este trabajo es una propuesta metodológica de construcción de índices de sostenibilidad para las ganaderías de bovino de leche en Cantabria. Mediante análisis factoriales de componentes principales, se obtienen 12 indicadores, 4 por cada dimensión (económica, ambiental y social), que permiten crear tres índices sintéticos de sostenibilidad y uno global. Las dimensiones que alcanzan mayores puntuaciones son la ambiental y la social en detrimento de la económica. Además, se observa una relación directa entre la sostenibilidad global y el tamaño productivo que, no se detecta para la dimensión ambiental, pero si en la social y económica.

Este estudio tiene como objetivo analizar las decisiones neuroeconómicas de pequeños productores de fibra de alpaca y papa nativa considerando la Teoría de la Jerarquía de Patrones Neuronales y el Modelo de la Memoria Temporal. Se pretende medir el impacto en el nivel de correlación de las competencias holísticas de innovación en el proceso de aprendizaje basado en el emprendimiento. Para ello se realizó una investigación de tipo experimental, transaccional, correlacional y descriptiva con una muestra de 88 individuos. Se aplicó una metodología de alineamiento de patrones neuronales emocionales. Los resultados muestran que (H1:Y0 > Y1), acentuando fibra de alpaca.

El objetivo es evaluar si los precios del frijol presentan volatilidad y si tiene implicaciones en la seguridad alimentaria de la población. Se aplicaron modelos simétricos y asimétricos de la familia ARCH a tres variedades de frijol en ocho mercados mexicanos. Los resultados mostraron una alta persistencia de volatilidad en frijol pinto y negro, la cual es mayor en los mercados locales que en los que tienen diferente punto de origen y destino. Por lo que dicha volatilidad impacta sobre las decisiones de consumo de la población más pobre.

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,and such support is weaker than what is obtained from the parametric models, particularly among medium and large landholders.

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 useof 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.

Este estudio evalúa la contribución de la agroecología a la seguridad alimentaria y contra el cambio climático en la agricultura familiar en la cuenca Mariño (Perú). Utilizamos como marco analítico los tres principios de la Agricultura Climáticamente Inteligente (CSA). Realizamos encuestasy mediciones en campo, evaluando tres principios, 10 criterios y 12 indicadores. Encontramos que la aplicación de prácticas agroecológicas mejora la autosuficiencia alimentaria e ingresos familiares; asimismo, reduce los antagonismos o incrementa sinergias entre productividad y adaptación o mitigación. Ello sugiere que la agroecología puede ayudar a alcanzar simultáneamente los objetivos (amenudo conflictivos) de la CSA.

Vegetable production is common in peri-urban agriculture where produce is sold in nearby towns, and the Santiago Metropolitan Region (SMR) in Chile is no exception. 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 suggestthat different characteristics and strategies are concomitant to certain attitudes that vegetable growers hold towards key aspects such as innovation or willingness to associate.

In Ecuador, since 2017, the representativeness of full employment had been showing a decline among the number of employed persons in rural and urban areas. This structural problem joins a break in economic growth of the country and the region. In this sense, this study aims to highlight the factors that determine access to non-full employment of young people in rural areas. For this, the estimation of a probit model is carried out. The results show the need to establish differentiated policies for access to full employment for rural youth.

The result of a LA-AIDS showed that the food consumption of poor households in West Java is influenced by its own-price, the price of other commodities, income, number of household members, household location, education of the head of household, and work type of the head of the household. The own-price elasticity identified that the price increase in each commodity group does not affect the consumption of the general food group. The cross-price elasticity of food groups showed more complementary.
