“…The average annual erosivity is 6,738 mm ha -1 h -1 year -1 , with 62% of the annual erosion potential occurring from December to February (Lombardi & Moldenhauer, 1992). The history of the experimental area is described in Marques (1951), Marques et al (1961) and Tengberg et al (1997). …”

“…In Brazil, the association of physical losses caused by erosion with their economic aspects is not new (Telles et al, 2013b), but this approach was considered in a few studies (Marques et al, 1961;Sorrenson & Montoya, 1989;Martin et al, 1991;Marques, 1998;Rodrigues, 2005;Bertol et al, 2007;Sarcinelli et al, 2009;Dantas & Monteiro, 2010;Pugliesi et al, 2011;Andrade et al, 2011). Although these have addressed only the losses of nutrients in the production unit (on-site), representing a small portion of the total costs of soil erosion (Crosson, 1995), this information is important for farmers, researchers and policy makers to form their opinions on the conservation management practices.…”

The aim of this study was to estimate water erosion costs associated with nutrient losses in four different rates of artificial cover. The experiment was carried out from 1987 to 1996 in runoff plots to measure soil losses in Campinas, State of Sao Paulo, in an Ferralsol under natural rainfall. The experimental design was completely randomized, with four treatments (0%, 24%, 40% and 90% artificial cover) and three replications. To estimate costs, P, K + , Ca 2+ and Mg 2+ concentrations in runoff water and soil removed by erosion were summed up, converted into triple superphosphate, potassium chloride and dolomitic limestone and multiplied by their respective market prices. The results indicate that, under the experimental conditions, the greater the percentage of soil cover, the lower the losses of water, soil, organic matter and nutrients. The soil with 90% cover presented reduction of 51.97% in average water losses, 54.44 in soil losses and 54.91% in organic matter losses than the treatment with 0% cover. In bare soil, losses were estimated at 16% P 2 O 5 and 8% KCl in terms of the amount of fertilizers recommended. Costs varied from US$ 107.76 ha -1 year -1 in bare soil (0% cover) to US$ 18.15 ha -1 year -1 in soil with 90% cover. With these values, losses were estimated at 616.5 million tons of soil per year for Brazil, as a result of soil erosion in annual crops, and cost of this process is around US$ 1.3 billion per year.

“…João Quintilliano de Avellar Marques was one of the pioneers of this institution. Marques et al (1961) were the first Brazilian researchers to associate soil erosion with economic issues, estimating the cost-benefit for soil use and the financial returns of conservation. Bertoni & Lombardi Neto (2008) also discussed the economic importance of soil conservation.…”

The aim of this study was a survey of the estimated costs of soil erosion, an issue of fundamental importance in view of the current worldwide discussions on sustainability. A list was drawn up of research papers on erosion (on-site and offsite effects) and their respective costs. The estimates indicate the amount of resources spent in the process of soil degradation, raising a general awareness of the need for soil conservation. On-site costs affect the production units directly, while off-site costs create a burden borne by the environment, economy and society. In addition, estimating the costs of soil erosion should be effective to alert the agricultural producers, society and government for the need for measures that can be implemented to bring erosion under control. Among the various estimates of soil erosion costs between 1933 a 2010, the highest figure was 45.5 billion dollars a year for the European Union. In the United States, the highest figure was 44 billion dollars a year. In Brazil, estimates for the state of Paraná indicate a value of 242 million dollars a year, and for the state of São Paulo, 212 million dollars a year. These figures show, above all, that conservation measures must be implemented if crop and livestock farming production are to be sustainable. Index terms: soil degradation, on-site and off-site losses, sustainable development. RESUMO: OS CUSTOS DA EROSÃO DO SOLO

In this article the environmental and socio-economical impacts ethanol production from sugarcane in the state of São Paulo (Brazil) are evaluated. Subsequently, an attempt is made to determine to what extent these impacts are a bottleneck for a sustainable and certified ethanol production. 17 environmental and socio-economic areas of concern are analysed. Four parameters are used to evaluate if an area of concern is a bottleneck: (1) the importance of the area of concern, based on the severity of the impact and the frequency of which an aspect is mentioned in the literature as an area of concern, (2) the availability of indicators and criteria, (3) the necessity of improvement strategies to reach compliance with Brazilian and/or (inter)national legislation, standards, guidelines and sustainability criteria, and (4) the impact of these improvement strategies on the costs and potential of ethanol production. The availability of data allowed for the calculation of these costs for 12 criteria; the results indicate an increase of the production costs by 36% compared to convential ethanol production. In total 14 areas of concern are classified as a minor or medium bottleneck. Two possible major bottlenecks are the protection of biodiversity and the production of food resulting from the competition for land with (the expected increase in) sugarcane production. Genetically modified cane is another (potential) major bottleneck considering the potentially large benefits and disadvantages, both which are at this moment highly uncertain.
