Brazil's drought: River levels rise after declines

Brazil's drought: River levels rise after declines

Sao Paulo, 23 October (Argus) — Brazilian grain and fertilizer shipments remain at risk from low river levels along key waterways, as the worst drought in Brazil's history continues to hamper inland navigation. But rivers have recovered this week, because of increased rainfall in the country, with their levels rising again after almost a month of extended declines. Madeira waterway The Madeira waterway links Rondonia state's capital Porto Velho to Itacoatiara port in Amazonas state, and is the second largest in the northern region. Itacoatiara is expected to receive around 70,634 metric tonnes (t) of fertilizers in October, according to line-up data from shipping agency Unimar. The Madeira river's depth at Porto Velho increased to 91cm on 23 October, from 46cm on 18 October, according to monitoring data from Brazil's geological survey SGB. But navigation remains suspended at the port after the state's ports and waterways authority SOPH halted operations on 23 September in response to the Madeira registering its lowest level since monitoring began in 1967. Amazon waterway The Amazon River is the main waterway in northern Brazil, handling around 65pc of the region's cargo, according to national transportation and infrastructure department DNIT. It links Amazonas state capital Manaus to Para state capital Belem. The Negro river's depth was at 12.56m at the SGB monitoring point in Manaus on 23 October, up from 12.46m on 18 October. This still exceeds the previous historic low of 12.7m over the past 121 years of monitoring. Tapajos waterway Tapajos is an important waterway for moving product from the northern part of Mato Grosso state to Santarem port in Para state. Santarem is expected to receive 130,234t of fertilizers in October, according to line-up data from Unimar. The Tapajos-Teles Pires waterway is also facing a dire situation. National water and sanitation agency ANA declared a water shortage on the Tapajos river on 23 September. Drier than usual weather has reduced river levels — especially between Itaituba and Santarem cities, in Para state — to below the historic minimum. The depth of the Tapajos at the Itaituba monitoring point, where the transfer point for the Miritituba waterway is located, was 1.03m on 23 October, up from 92cm on 18 October but still below the previous record low of 1.32m, according to SGB data. At the Santarem monitoring point, the Tapajos was at 27cm, a level considered to be dry. The level was 28cm on 18 October. The historic minimum at the location is -55cm below the port's reference point. A level below zero does not mean the river is dry, but indicates extremely low levels. Tocantins-Araguaia waterway The Tocantins-Araguaia waterway encompasses the Araguaia and Tocantins rivers. It runs from Barra do Garcas city, in Mato Grosso, into the Araguaia river, or from Peixes city, in Tocantins state, into the Tocantins river to the port of Vila do Conde, in Para state. Soybeans, corn, fertilizers, fuels, mineral oils and derivative products are transported along the northern waterways. Vila do Conde is expected to receive 245,500t of fertilizers in October, according to Unimar. The SGB has two monitoring points on the Araguaia river. In Nova Crixas city, in Goias state, the river was at 3.11m on 23 October, up from 2.85m on 18 October, surpassing the previous historic minimum of 3.10m. In Sao Felix do Araguaia city, in Mato Grosso state, the Araguaia was at 2.71m, up from 2.56m on 18 October, recovering from extreme drought-like levels and moving away from the historic low of 2.51m.
