Políticas públicas y agriculturas familiares en América Latina y el Caribe: balance, desafíos y perspectivas

Este libro reúne un conjunto de estudios de caso y un análisis transversal de las políticas públicas para la agricultura familiar en once países latinoamericanos. Aborda la situación de las agriculturas de base familiar en cada uno de ellos y la evolución de las políticas enfocadas o que inciden directamente en ella, así como las definiciones, tipologías e instrumentos para orientar y aplicar esas políticas. Finalmente, valora sus resultados e impactos, sus perspectivas actuales y los principales desafíos que enfrentan dichas políticas y las diversas agriculturas familiares del hemisferio.

Componentes principais na elaboração de índices de provas de desempenho em bovinos

The principal component analysis assists the producers in making decision of which evaluated features must be maintained in performance tests indexes, according to the variation present in these animals evaluated. The objective in this study was to evaluate a set of characteristics measured in a performance test in semifeedlot cattle of the Simmental and Angus breeds, by means principal component analysis (PC), aim to identify the features that represent most of the phenotypic variation for preparation of indexes. It was used data from 39 Angus and 38 Simmental bulls from the Santa Éster farm, located in Silvianópolis - MG. The performance test period was from october 2014 to february 2015. The features evaluated in the test were: final weight (FW), average daily gain weight (GW), respiratory rate (RR), haircoat temperature (HT) and rectal (RT), hair number (HN), hair length (HL), hair thickness (HT), muscularity (MUSC), racial characteristics, angulation, reproductive and balance (BAL), height of the front and back, width and length of croup, body length, depth and heart girth, subcutaneous fat thickness and rump (FTR), loin eye area and marbling (MAR). It was used PRINCOMP from SAS program for procedure the PC analysis. It was found that of the 27 features evaluated, the first four PC for Simmental breed explained 74% total variation data. The four PC selected with the corresponding weighting coefficients formed the following index: (0.27 * FW) + (0.47 * MUSC) + (0.50 * HL) + (0.39 * HT). Since the characteristics related to the adaptability of great importance for the studied breed, it was decided to keep the index of evidence for the Angus breed, the feature hair number, because there is a feature that presented a great variability and occupied one of the first principal component. Thus, the Angus index was composed by five features, with 79% total variation data, resulting in the following formula: (0.26 * FW) + (0.33 * BAL) + (0.58 * MAR) - (0.43 * FTR) – (0.38 * HN). By the principal component analysis it was possible to minimize the features number to be evaluated on performance tests from that farm, making the animal selection rapidly and accurate.

Centroamérica y República Dominicana: evolución económica en 2015 y perspectivas para 2016. Balance preliminar

El presente documento hace un balance preliminar de las economías de Centroamérica y la República Dominicana (CARD) en 2015 y ofrece perspectivas para 2016. Es un análisis de aoyuntura elaborado por la Unidad de Desarrollo Económico de la sede Subregional de la CEPAL en México, con información disponible al 31 de enero de 2016. En primer lugar se analiza el contexto internacional, en particular los eventos que impactan directamente a las economías de CARD. En segundo término, se presentan los rasgos generales de la evolución económica de los países bajo estudio, para, en tercer lugar, hacer un análisis en materia de política fiscal, monetaria, cambiaria y comercial. En cuarto lugar, se estucia la evolución del sector externo y, por último, se analiza la actividad económica, los precios y el empleo.

Radiation balance in a soybean ecosystem in the Amazon

O avanço da fronteira agrícola na Amazônia, da forma como vem sendo realizado, tem deixado a comunidade cada vez mais preocupada ante os possíveis impactos ambientais decorrentes desta mudança no uso da terra, devido à grande importância que a Amazônia representa para o clima global. Neste trabalho avaliaram-se os componentes do balanço de radiação à superfície, ao longo do ciclo da soja (Glycine Max (L.) Merryl), em uma área de avanço da fronteira agrícola na Amazônia. Os componentes do balanço de radiação foram monitorados continuamente durante o ciclo da soja, em 2006 e 2007, em uma área de 200 ha de extensão. O monocultivo da soja na Amazônia apresentou uma contínua mudança nos componentes do balanço de radiação, tendo como consequência uma redução na energia disponível para o ambiente devido o aumento na reflexão da superfície. Observou-se uma importante contribuição da radiação solar difusa na interceptação da soja durante dias nublados, mesmo sob condições de dossel incompleto. Por outro lado, após o fechamento do dossel, a interação da soja com a radiação acontece de forma semelhante, independente da condição de nebulosidade.

Nutritional balance and yield for green manure orange trees

Intercropping could efficiently prevent soil nutrient losses caused by extensive agriculture. The present study aimed to assess the effect of green manure on the nutritional status of orange trees cultivar 'Pera' (Citrus sinensis (L.) Osbeck). The plants were grafted on 'Cravo' lime trees and were then planted in a 7x4m space. Four different treatments corresponding to the evaluated green manures were employed: jack bean (JB) (Canavalia ensiformis DC), lablab (LL) (Dolichos lablab L.), pigeon pea (PP) (Cajanus cajan L. Millsp), and Brachiaria (BQ) (Brachiaria brizantha Hochst ex A. Rich. Stapf) as control. The experimental design was in randomized blocks, in split-plot time, with six replicates, with four treatments (green manures) and two plants per evaluation. The nutritional status was assessed by using the DRIS method (Diagnosis and Recommendation Integrated System); the yield and the macro and micronutrient levels contained in green manures and in the control was also determined. The nutritional diagnosis indicated that, in the two years of experiment, plants treated with green manure showed better nutritional balance index compared to Brachiaria. This suggests that, over time, green manure can lead to better nutritional balance. Pigeon pea treatment showed the highest yields, compared to control, in the two evaluated crop cycles (2004/05 and 2005/06).
