Latin America and the Caribbean (LAC) countries are among the global leaders in the production and exports of agricultural and fisheries commodities, accounting for 15% of the world's average agri-food export from 1995 to 2019. With rising global market competitiveness, considering the agri-food sector, it is important to assess if the region can compete against other global rivals, and in what products. Accounting for regional potential economic power, remarkable agricultural food export and market expansion, this paper explored the LAC agricultural trade patterns and export competitiveness through the analysis of the Revealed Comparative Advantage (RCA) index, and its modifications - SRCA (Symmetric Revealed Comparative Advantage), RTA (Relative Trade Advantage, and RC (Revealed Competitiveness) - in the agricultural sector for the period of 1995-2019. This paper contributes to the literature by presenting the export characteristics in Latin American developing countries, which can be an important instrument for decision-makers in the agricultural trade policy. Throughout the research period, the results indicated that Brazil, Argentina, and Mexico were the TOP agri-food exporters in LAC. The highest RCA, SRCA, and RTA were found in Guatemala, whereas the greatest RC was found in Argentina. At the product level analysis, oil seeds and oleaginous fruits, miscellaneous grains, seeds and fruit, industrial or medicinal plants, and straw and fodder (HS12) were the most exported items at the 2-digit level. Fruit and nuts, edible; peel of citrus fruit or melons (HS08) had the most competitiveness in the worldwide market, with the highest SRCA and RC indices, whereas coffee, tea, mate, and spices (HS9) had the highest BRCA and RTA values. The evidence suggests that among the TOP 10 exporters in LAC, all indices in the global agri-food trade are said to be relatively stable, whereas survival rates do not persist over time.

This paper aimed to analyze the relationships between the variables price, consumption and supply of electricity in rural Brazil and the different public pricing policies applied to the sector. To this end, an autoregressive time series model (VAR) and Granger causality are used, with data from the rural electricity sector, from 1996 to 2020, distributed quarterly. Among the contributions, it is observed that the policy of universalization of access to electrification can be considered a success regarding the number of consumer units reached, however, there is a need for a review regarding the pricing policies applied, since there is a bidirectional relationship, in which Production causes Consumption and Consumption causes Production, but Price does not cause Production, but causes Consumption. This is in line with the results of the VAR model which show that an increase in the price of energy in the Rural Zone would reduce its consumption, negatively impacting productivity, since energy is an important input for production and income in the agricultural sector.

This work presents a review related to the obtainment of cellulose from different structures in agro-industrial residues, both for application in the food industry and for the reinforcement of other materials. Cellulose nanofibers are produced by the heart of palm (Bactris gasipaes) industry in Brazil and are used as a stabilizer in avocado oil emulsions; conversely, cellulose nanocrystals are produced in waste from the tequila industry (Agave tequilana Weber var. Azul) in Jalisco, Mexico, and are used for reinforcement applications. [ABSTRACT FROM AUTHOR]

Business cycle analysis faces the challenge of high-dimensional databases with a time-irregular span. This study addresses these issues to estimate the Brazilian agricultural business cycle by proposing the use of an entropic test of relative information and the estimation of a generalized dynamic factor model in the context of a time-irregular span. In addition, we assess the co-movements between the estimated cycle and a wide range of weather, macroeconomic, and sectoral variables. The main results are: (i) the sharpest crises of the agricultural cycle are associated more with weather events than with Brazil's economic crises, reinforcing that agriculture has a stabilizing role in the aggregated cycles; (ii) among all the variables analyzed, those related to weather (minimum and maximum temperature and precipitation) present the greatest commonalities with the agricultural cycle and are leading indicators; (iii) minimum temperatures and precipitation in states are essentially pro-cyclical, while maximum temperatures are pro-cyclical in typically colder states and counter-cyclical in warmer states; (iv) following the weather variables, credit variables had the highest average commonalities, with phases of expansion in the agricultural cycle leading to contractions in the indicators of arrears and defaults and in the interest rate of rural credit, with some time lag; (v) the behavior of the Brazilian economy and global demand for imports are also antecedent and pro-cyclical, but with relatively smaller commonalities; and (vi) expansions of the agricultural cycle lead to contractions in the unemployment rate of the economy. The contribution of this study is twofold: (1) its methodological innovation and (2) its application to the Brazilian agricultural business cycle, both of which are unprecedented.

The Xingu River Basin (XRB) in the Brazilian Amazon region has a great relevance to the development of northern Brazil because of the Belo Monte hydropower plant and its crescent agribusiness expansion. This study aimed to evaluate the potential of the Lavras Simulation of the Hydrology (LASH) model to represent the main hydrological processes in the XRB and simulate the hydrological impacts in the face of land-use change scenarios. Following the trend of the most relevant agribusiness evolution in the XRB, four agribusiness scenarios (S) were structured considering the increase in grasslands (S1: 50% over the native forest; S2: 100% over the native forest) and soybean plantations (S3: 50% over the native forest; S4: 100% over native forest). Average hydrographs were simulated, and the frequency duration curves (FDC) and average annual values of the main hydrological components for each scenario were compared. The results showed that, in general, changes in land use based on deforestation in the XRB would lead to an increase in flood streamflow and a reduction in baseflow. The increases in direct surface runoff varied from 4.4% for S1 to 29.8% for S4 scenarios. The reduction in baseflow varied from −1.6% for S1 to −4.9% for S2. These changes were reduced when the entire XRB was analyzed, but notable for the sub-basins in its headwater region, where the scenarios were more effective. [ABSTRACT FROM AUTHOR]

Purpose: Driven by scientific and technological intensification, Brazilian agribusinesses are among the main food producers and exporters worldwide. Knowledge management contributes to the development of agribusinesses. The objective of this study is to analyze knowledge management practices in the supply chain of broilers at the level of farmers and compare the differences between farmers who are members of cooperatives, and those who are suppliers of firms. Design/methodology/approach: Using data from a sample of broiler farmers (n = 240, where 80 respondents are associated with cooperatives) from Brazil, descriptive statistics were used to measure the four knowledge management dimensions (leadership, people, process and technology). The Mann–Whitney test was performed to verify the difference in the adoption of knowledge management practices between farmers who are members of cooperatives, and those who are suppliers of firms. Findings: The results showed significant differences between the analyzed groups of broiler farmers that are members of an agricultural cooperative and suppliers of firms. Farmers who supply firms adopt knowledge management practices with greater intensity. They are also more technified and have a larger scale of production. Research limitations/implications: The study was conducted in a single agribusiness chain. Future studies may look at another method of knowledge management assessment to see if the results will be similar. Practical implications: The results can contribute to the development of programs and policies, incorporating knowledge management into agribusiness as a competitive strategy. Originality/value: While knowledge management is a widely studied topic, there has been little focus on this subject with regard to agribusiness. Empirical findings of an important agribusiness supply chain are provided and show the differences in knowledge management perceptions between farmers who are members of cooperatives and those who are suppliers of firms.
