Embrapa presents results of Agricultural Climate Risk Zoning

The main results obtained with the new methodologies adopted for Agricultural Climate Risk Zoning (Zarc) will be presented in Campinas (SP), from November 21st to 23rd, during a workshop hosted by Embrapa Informática Agropecuária. Researchers, technicians and sector leaders working on the topic will discuss technical criteria validated for different cultures in different regions of the country, in addition to demands from the risk management sector, among other topics.

The grape's new Zarc is one of the topics highlighted at the technical event. On the 21st, Embrapa Grape and Wine researcher Marco Conceição, who coordinated the updates for the crop, will present the criteria used for the state of São Paulo. “The methodology used takes into account the characteristics of the climate, soil and culture, and seeks to quantify the climatic risks that can cause losses in production in the various Brazilian wine-growing regions”, says the coordinator. The event will also include the validation of the proposal with technicians and representatives of the state's productive sector.

The first Zarc Uva ordinances, published for the 2005/2006 harvest, covered the states of Rio Grande do Sul, Santa Catarina, Paraná, São Paulo, Bahia and Pernambuco, with specific criteria for each state. The new version of this zoning unified the criteria presented. “Based on the different variables, the occurrences of frost and drought were considered as the main climatic risks, thus standardizing the climatic indices for the whole of Brazil”, explains Conceição.

Other cultures that have been reevaluated, or that have had their zoning methodologies improved, will also be the topic of the workshop. Among them are: peanuts, bananas, cocoa, Phaseolus beans, cactus and soybeans. After validating the proposal prepared by Embrapa, the Ministry of Agriculture, Livestock and Supply (Mapa) will officially publish it in ordinances in the Official Gazette of the Union (DOU). The general coordinator of Zarc at Embrapa and researcher at Embrapa Informática Agropecuária, José Eduardo Monteiro, clarifies that the new results will be consolidated in a report, which will be sent to Mapa for publication in the DOU, by the end of this year.

An innovation that will be presented at the event is the first Agricultural Risk Zoning of Climate Productivity (Zarp), for irrigated rice in Rio Grande do Sul, developed through a partnership between Embrapa, the Federal University of Santa Maria (UFSM) and the Instituto Riograndense do Arroz (Irga) and already published by Mapa. Zarp irrigated rice is generated from SimulArroz, a process-based ecophysiological model that simulates the development, growth and productivity of rice in flood irrigation systems, practiced in the state of Rio Grande do Sul. This type of zoning , in addition to incorporating a greater number of climatic variables with greater precision, it opens up possibilities for generating risk zoning for different expectations or expected productivity.

Another novelty is the Zarp methodology for beef cattle farming, developed by Embrapa Informática Agropecuária and Embrapa Pecuária Sudeste (São Carlos, SP). Zarp beef cattle is generated from a pasture productivity model associated with a forage budgeting model, allowing the risk to be estimated for different combinations between maximum stocking rate levels and food supplementation.

Zarc

O Zarc It is an instrument of agricultural policy and risk management in agriculture, which guides rural producers on the best time to plant and sow crops, aiming to reduce agricultural losses. Developed to offer more safety and efficiency to the work of rural producers, it seeks to predict the possibility of damage to agricultural plantations due to climatic and geographical conditions, considering the ideal date for sowing with low climatic risk, cultivars adapted to the region and type of soil for the crop. cultivation. The system generates planting calendars and a list of municipalities that indicate when and where a given crop will have the greatest chance of success.

Currently, zoning is done for 44 species and plant production systems in Brazil. To modernize and increase effectiveness, the program periodically receives a review of its technological supports, information and methodologies. Constant improvement combines the use of advanced computational tools and technical-scientific knowledge accumulated in various institutions and in specialized publications, national and international. “Data such as precipitation, temperature and water consumption are taken into account to increase the chance of success in the crops analyzed”, says researcher Aryeverton Fortes de Oliveira, from Embrapa Informática Agropecuária.

Participating in the workshop, as speakers, are representatives from Mapa, the Central Bank, the Brazilian Agriculture and Livestock Confederation (CNA) and the National Federation of General Insurance (Fenseg). Employees from the following Embrapa Units will still be present: Acre, Cotton, Amapá, Rice and Beans, Cerrados, Temperate Climate, Forests, Agricultural IT, Mid-North, Corn and Sorghum, Southeast Livestock, Soy, Soils, Fishing and Aquaculture, Semiarid , Coastal Boards, and Grape and Wine.
