The use of multi-criteria analysis in the recovery of abandoned mines: a study of intervention in Portugal

Considering that the budget for the recovery of abandoned mining zones is limited, it was necessary to develop a model that would make it possible to choose which mines should be targeted for intervention, taking into account the various factors by which their external effects may be assessed (the environment, public health, the landscape and their usefulness to industrial archaeology). A multi-criteria analysis using the analytic hierarchy process, in which each major factor, result, and mine are compared, was employed to generate an innovative assessment model that guaranteed that the overall value of the intervention was maximised, compared to two other methods (intervention ranked by the greatest overall severity and ranked by the cost–benefit ratio). The results indicate an economically and socially viable and efficient choice, making it possible to undertake new similar studies. © 2018 Departamento de Administrac¸ao, Faculdade de Economia, Administrac ˜ ¸ao e Contabilidade da Universidade de S ˜ ao Paulo – FEA/USP. ˜ Published by Elsevier Editora Ltda.

The use of multi-criteria analysis in the recovery of abandoned mines: a study of intervention in Portugal

Tendo em consideração a existência de uma limitação orçamentária que inviabilizava a recuperação de todas as áreas mineiras abandonadas, foi necessário desenvolver um modelo que permitisse escolher quais as minas que seriam objeto de intervenção, tendo em consideração os diferentes fatores de avaliação de seus efeitos externos (no ambiente, na saúde pública, na paisagem e no seu aproveitamento para a arqueologia industrial). A partir de uma análise multicritério (utilizando o Analytical Hierarchy Process - AHP), onde cada fator preponderante, resultado e mina foram comparados, gerou-se um modelo inovador de avaliação onde se garantiu a maximização do valor global da intervenção, em comparação a outros dois métodos (intervenção ordenada pela maior gravidade global e pela relação custo-benefício). Os resultados apontam para uma escolha econ×mica e socialmente viável e eficiente, permitindo instigar novos estudos análogos.Considering that the budget for the recovery of abandoned mining zones is limited, it was necessary to develop a model that would make it possible to choose which mines should be targeted for intervention, taking into account the various factors by which their external effects may be assessed (the environment, public health, the landscape and their usefulness to industrial archaeology).

Exploring Local Maize Diversity for Increased Agricultural Sustainability: New Insights into Drought Stress Response and Recovery of Guinea-Bissau Landraces

Landraces are rightfully known as the backbone of sustainable food production, particularly in areas experiencing significant environmental constraints. However, protecting landraces from genetic erosion and valuing their potential for plant breeding and sustainable food production requires in-depth understanding of their phenotypic traits. Two Guinea-Bissau landraces (GA, GV) and two elite cultivars (P98438, P0023) were subjected to drought stress for 7 (S1) and 12 (S2) days. After this period plants were rewatered (R). The relative water content (RWC) was unchanged in S1 and decreased in S2 in all genotypes. Chlorophyll a fluorescence parameters changed moderately in S1 and remarkably in S2, including on GA and GV plants, where a decrease of Fv/Fm and PI, and an increase in absorbed, trapped, and dissipated energy per reaction center, was found. P0023 plants showed the most contrasting behavior to Guinea-Bissau genotypes, presenting an increase in Fv/Fm and PI values and a decrease in the specific energy fluxes per reaction center (RC), whereas P9838 presented an intermediate behavior. Drought (S1 and S2) decreased the amount of chlorophyll (Chl.) and carotenoids in GA and GV plants. On the contrary, in the P0023, the only pigment to decrease with stress was Chl. b. Fatty acid (FA) analyses allowed for the identification of C16:0, C18:2, and C18:3 in larger amounts, and C14:0, C16:1t, C18:0, and C18:1 acids in lower abundance. Drought stress decreased C18:3, the double bond index, and the total FA (except for P0023 and GV in S2) and increased C14:0 and C16:0 acids. The expression of phospholipase D (PLD) was higher at S2. After recovery, PLD expression presented a notorious decrease on the Guinea-Bissau landraces. P0023 showed the smallest alterations after recovery, while Guinea’s plants suffered more radical alterations leading to the conclusion that Guinea’s landraces were more drought-sensitive and that their recovery rate was impaired.info:eu-repo/semantics/publishedVersio

Estoque de carbono no solo após manejo nutricional de pau-de-balsa

The objective of this work was to evaluate whether balsa wood plantation and its fertilization can improve soil carbon stocks. Total carbon stocks in the soil-biomass system, at 0.0-0.30 m soil depths, were evaluated under three fertilization strategies, after three and seven years, and compared with carbon stocks from native forest and degraded pasture. At the highest fertilization level, balsa wood showed a carbon stock similar to that of the native forest (65.38 Mg ha-1) and, after seven years, it increased carbon stock by 18% in the soil, and by 42% in the soil-biomass system.O objetivo deste trabalho foi avaliar se o plantio de pau-de-balsa e seu manejo nutricional aumentam os estoques de carbono no solo. Os estoques de carbono total do sistema solo-biomassa à profundidade de 0,0–0,30 m foram avaliados em três níveis de adubação, após três e sete anos, e comparados com mata nativa e pastagem degradada. No nível de maior adubação, o pau-de-balsa apresentou estoque de carbono semelhante ao da mata nativa (65,38 Mg ha-1) e, após sete anos, aumentou o estoque de carbono em 18%, no solo, e em 42%, no sistema solo-biomassa

Aggregate stability and carbon and nutrients distribution in an Acrisol under organic and mineral fertilization

O objetivo deste trabalho foi avaliar o impacto da adubação orgânica e mineral sobre a estabilidade de agregados e a distribuição de C, N e P, em classes de agregados de um Argissolo Vermelho-Amarelo. Os tratamentos consistiram de 0 e 40 m3 ha-1 por ano de adubação orgânica e de 0, 250 e 500 kg ha-1 de adubação mineral N–P–K da fórmula 4–14–8. Uma área sob floresta atlântica foi utilizada como referência. Amostras foram coletadas nas camadas de 0–10 e 10–20 cm. Houve predomínio da classe de agregados entre 4 e 2 mm, que correspondeu a 39,7% do total de agregados separados por via seca no tratamento com composto orgânico. Os teores de C orgânico total para adubação orgânica foram 17,5 e 36,7% maiores para as classes 4–2 e 0,105–0,25 mm. A adubação orgânica contribuiu para teores de N e P totais de 43 e 38,7% (0–10 cm) e 35,4 e 36,8% (10–20 cm), maiores que os dos tratamentos sem adubo orgânico. A relação carbono/nitrogênio se manteve constante entre as classes de agregados de um mesmo tratamento, enquanto a de carbono/fósforo reduziu com o uso de adubo orgânico ou mineral, em relação à mata nativa. Os índices de estabilidade de agregados se correlacionaram positivamente aos teores de carbono orgânico total da classe 4–2 mm.The aim of this work was to evaluate the effect of mineral and organic fertilization on the soil-water aggregate stability and on the distribution of C, N and P in different classes of aggregates in an Acrisol. The treatments were 0 and 40 m3 ha-1 per year of organic fertilizer and 0, 250 and 500 kg ha-1 of mineral fertilizer N–P–K of the formula 4–14–8. An area under Atlantic forest was used as reference. Soil samples were collected at 0–10 and 10–20 cm depths. The distribution of aggregates showed the highest values from 4 to 2 mm. In the organic fertilizer treatment, the aggregates 4–2 mm corresponded to 39.7% of the total on the soil. For the aggregates 4–2 and 0.105–0.25 mm, the total organic carbon contents were 17.5 and 36.7% higher in the organic fertilizer treatments. The organic fertilization contributed to values of N and P of 43 and 38.7% (0–10 cm) and 35.4 and 36.8% (10–20 cm), which were higher than the treatments without organic fertilizer. The carbon/nitrogen ratio did not vary among the aggregate classes in the same treatment. However, the carbon/phosphorus ratio was reduced with the use of organic and mineral fertilizer. The indexes of aggregates stability were positively correlated with the content of total organic carbon in the 4–2 mm

Liquid nitrogen fertilization on the yield and phenologic variables of narrow-row cotton

Slow-release liquid nitrogen fertilizer sources have been around since 1970. However, this technique is not widely used in the field, probably due to the low cost per ton of nitrogen in the solid form. This study aimed to evaluate the combination of the conventional and slow-release nitrogen fertilization on the yield and phenological variables in a narrow-row cotton crop. Treatments consisted of the combination of the nitrogen fertilizer applied as topdressing in solid form (via soil) and pulverized in the liquid form (via urea formaldehyde - UF): 0% of solid N + 0% of liquid N (0S0L); 100% of solid N + 0% of liquid N (100S0L); 75% of solid N + 25% of liquid N (75S25L); 50% of solid N + 50% of liquid N (50S50L); 25% of solid N + 75% of liquid N (25S75L); e 0% of solid N + 100% of liquid N (0S100L). The cotton crop was phenotypically evaluated at 35, 70, and 130 DAE (Days after emergence) and at the harvest time. The variation between the source of the solid nitrogen fertilizer applied to the soil (ammonium nitrate) and the liquid Nitrogen fertilizer applied by spraying (UF) affects the phenology, physiology, and yield components of the narrow-row cotton crop. The highest yield of the narrow-row cotton crop under the experimental conditions was achieved when 25% of the dose of the solid nitrogen fertilizer was applied as topdressing via soil, and 75% of the dose of the slow-release nitrogen fertilizer was sprayed. This technique provides higher profitability of the produced cotton in relation to the conventional application of the N solid fertilizer via soil
