Barley (Hordeum vulgare) is a globally significant cereal crop, widely used in both food production and brewing. However, it is particularly vulnerable to climate change, especially extreme temperature fluctuations, which can severely reduce yields. To address this challenge, a detailed climate zoning study was conducted to assess the suitability of barley production areas across South America, considering both current conditions and future climate scenarios from the Intergovernmental Panel on Climate Change (IPCC).

Article Synopsis
  • Yerba mate is culturally significant in South America and has notable nutritional and pharmaceutical benefits, leading to various patents on its properties.
  • This research utilizes the CMIP6 climate model to evaluate how climate change may impact the production and distribution of yerba mate across major growing regions in Brazil, Argentina, Paraguay, and Uruguay.
  • Findings indicate that many areas analyzed are currently non-conducive for yerba mate cultivation, highlighting the need for adaptive strategies to support sustainable production amid changing climate conditions.

Background: Climate influences the interaction between pathogens and their hosts significantly. This is particularly evident in the coffee industry, where fungal diseases like Cercospora coffeicola, causing brown-eye spot, can reduce yields drastically. This study focuses on forecasting coffee brown-eye spot using various models that incorporate agrometeorological data, allowing for predictions at least 1 week prior to the occurrence of disease.

Article Synopsis
  • The study focused on estimating the number of generations and cycle duration of major coffee pests in Paraná, Brazil, using thermal indices to improve pest control strategies.
  • Data on temperature and precipitation from 1984 to 2018 was analyzed, with calculations made for evapotranspiration and water balance methods to understand pest dynamics.
  • Results indicated that coffee pests are most severe in the warmer, northern regions of Paraná, which also have the highest coffee production, with altitude significantly influencing pest lifecycle variability.

Background: The loss of coffee leaves caused by the attack of pests and diseases significantly reduces its production and bean quality. Thus this study aimed to estimate foliation for regions with the highest production of arabica coffee in Brazil using nonlinear models as a function of climate. A 25-year historical series (1995-2019) of Coffea arabica foliation (%) data was obtained by the Procafé Foundation in cultivations with no phytosanitary treatment.

Background: Peanuts are widely grown in Brazil because of their great importance in the domestic vegetable oil industry and the succession of sugarcane, soybean and maize crops, contributing to soil conservation and improvement in agricultural areas. Thus, the present study aimed to determine the zoning of peanuts' climatic risk by estimating the water requirement satisfaction index (WRSI) for the crop in Brazil. We used a historical series of data on average air temperature and rainfall between 1980 and 2016.
