title: Objective assessment of ecosystem hydrological services in tropical areas: A Colombian experience in arid and semi-arid zones

description: Abstract This study presents a methodology to address the challenge of objectively demonstrating Ecosystem Hydrological Services (EHS). A case study is used in the region of the La Guajira Peninsula (Colombia), with a focus on the EHS of water flow regulation. The proposed methodology hypothesizes that EHS that have not been objectively demonstrated lead to failures in the implementation of guidelines of Payments for Ecosystem Services (PES). Following this idea, we have tried to understand and quantify the relationship between vegetation coverage and streamflow regulation. To prove this relationship and the existence of the mentioned EHS in the La Guajira Ecosystem, we determined land cover changes from 2000 to 2013 using the Normalized Difference Vegetation Index (NDVI), and we also quantified the streamflow regulation using hydrological and meteorological time series in the study area. The analysis methods used were insufficient to determine the influence of vegetation on hydric regulation EHS; nevertheless, a greater influence of morphometry was observed in medium-and large-sized basins. Another important finding shows the relevance of selecting an adequate spatial and time resolution when quantifying water flow regulation services and its relationship with land cover characteristics. In this way, this exercise shows the complexity of quantifying EHS. Furthermore, we highlight some aspects that must be taken into account to properly quantify streamflow regulation due to vegetation coverage.

title: Hydrological modeling of the Ribeirão das Posses - An assessment based on the Agricultural Ecosystem Services (AgES) watershed model

description: Abstract Southeastern Brazil has recently experienced drought conditions that have impacted watershed conservation and the management of water quality and quantity for agricultural and urban demands. The Ribeirão das Posses watershed is being monitored as a headwater of the Jaguarí River, which is one of the contributing rivers of the Cantareira Reservoir Complex in the state of São Paulo. The landscape has changed over the last century from native forests to more homogeneous vegetation for pastures, crops and some forest plantations of eucalyptus, which have cumulative impacts on water yield and quality. Currently, the Projeto Conservador das Águas (Water Conservationist Project) has planted small areas with native species vegetation in order to recover degraded areas. The objective of this study was to evaluate the quantity of water in the Ribeirão das Posses Basin by both measurements and by simulating hydrological responses. The Agricultural Ecosystem Services (AgES) watershed model was applied to simulate water movement and storage among land areas. The simulation period was from 2009 to 2014, because the daily streamflow and meteorological data were available for model calibration and testing. We discuss data input requirements, model calibration to fit measured streamflow, and sensitivity to spatially variable rainfall inputs. The calibrated model may be used to estimate streamflow during periods of missing data, and in the future to estimate impacts of land use changes on stream water quantity and quality. Such information can be used in programs of payments for ecosystem services.

title: Network Attributes Inter-State Mobility 2020 (Nigeria) - Modelling COVID-19 Impacts

description: The dataset consists of network attributes (vertex betweenness and nodal efficiency) computed to examine the impact of COVID-19 impacts on the economy. Spatial interaction is pertinent for economic activities, therefore we hypothesize that changes in the spatial interaction network will have a commensurate impact on the economic output of the node within the network. The data utilized for this computation were collated from Facebook Data For Good - GeoInsight Platform. From this we collected movement data capturing the number of Facebook user moving from one State to the other in Nigeria. The computation of the network attributes was carried out with R packages (brainGraph - nodal efficiency and igraph - betweenness).

title: Solid phase extraction using molecular imprinting polymers (MISPE) for the determination of estrogens in surface water by HPLC

description: Abstract Estrogens are emerging pollutants and traditional sewage treatments unable to remove them. They are harmful to human health and to the environment. It is therefore important to evaluate the presence and concentration of estrogens in water bodies and environmental matrices. This work presents the development and application of a methodology for the determination of E1, E3, EE2 and E2 in surface waters using solid phase extraction with molecular imprinting polymers (MISPE) followed by identification and quantification by HPLC-DAD. Acetonitrile and water deionized acidified with phosphoric acid pH 3 (1:1, v/v), a flow rate of 1.0 ml min-1, at 40°C and an injection volume of 5 µL. The method was validated according to the protocol ICH Q2R. Reproducibility and repeatability tests resulted in a smaller variation coefficient of 10%; the calibration curves in the concentration ranged from 1 to 20 mg L-1, with return linearity values greater than 0.99. The limits of detection and quantification were less than 1 mg L-1 and the method was satisfactory for specificity and selectivity tests using caffeine, which is often found in water bodies receiving effluent, and DES, an estrogen used in the treatment of prostate cancer. Selected samples underwent clean-up and pre-concentration treatments using solid phase extraction with commercial phase (C18) and molecularly imprinted polymers (MISPE). The analysis of MISPE extracts indicate that it is possible to obtain results with greater sensitivity and precision for analyses of complex environmental matrices, demonstrating that the developed method can be applied in complex environmental matrices.

title: Effects of global climate change on chlorophyll-a concentrations in a tropical aquatic system during a cyanobacterial bloom: a microcosm study

description: Abstract Recent studies have investigated the impact of climate change on aquatic environments, and Chlorophyll-a (Chl-a) concentration is a quick and reliable variable for monitoring such changes. This study evaluated the impact of rainfall frequency as a diluting agent and the effect of increased temperature on Chl-a concentrations in eutrophic environments during a bloom of cyanobacteria. This was based on the hypothesis that the concentration of Chl-a will be higher in treatments in which the rainfall frequency is not homogeneous and that warmer temperatures predicted due to climate change should favor higher concentrations of Chl-a. The experiment was designed to investigate three factors: temperature, precipitation and time. Temperature was tested with two treatment levels (22°C and the future temperature of 25°C). Precipitation was tested with four treatments (no precipitation, a homogeneous precipitation pattern, and two types of concentrated precipitation patterns). Experiments were run for 15 days, and Chl-a concentration was measured every five days in each of the temperature and precipitation treatments. The water used in the microcosms was collected from a eutrophic lake located in Central Brazil during a bloom of filamentous cyanobacteria (Geilterinema amphibium). Chl-a levels were high in all treatments. The higher temperature treatment showed increased Chl-a concentration (F=10.343; P=0.002); however, the extreme precipitation events did not significantly influence Chl-a concentrations (F=1.198; P=0.326). Therefore, the study demonstrates that future climatic conditions (projected to 2100), such as elevated temperatures, may affect the primary productivity of aquatic environments in tropical aquatic systems.

title: Initial development of cowpea plants under salt stress and phosphate fertilization

description: Abstract The objective of this work was to study the effects of irrigation with saline water associated with phosphate fertilization on the emergence and early growth of cowpea plants. The assay was conducted in the greenhouse of the Department of Environmental Sciences and Technology of the Federal Rural University of the Semi-Arid (UFERSA) in Mossoró-RN, during October and November of 2015. The study adopted a randomized block with treatments arranged in a 5 x 3 grid, corresponding to five levels of water salinity (0.5, 1.5, 2.5, 3.5 and 4.5 dS m-1) and three doses of superphosphate, based upon the soil analysis (60%, 100% and 140% of the recommended dose for the crop 60 kg P2O5 ha-1), with five repetitions. The cowpea plants, cv. Paulistinha, were grown in lysimeters with capacity of 8 dm3. During the first 15 days of the initial stage of development the plants were evaluated for emergence, growth and biomass accumulation. The increase in water salinity above 1.5 dSm-1 reduced the emergence, growth and dry matter accumulation of cowpea plants. The increase of 40% in the recommendation of phosphorus fertilization of cowpea increased the growth and biomass accumulation of shoot plants, regardless of salinity.

title: Bioaccumulation of heavy metals in Oncorhynchus mykiss for export at production centers in the Peruvian Central Highlands

description: Abstract The bioaccumulation of the heavy metals Cu, Zn, Fe and Pb was determined in the livers, kidneys and muscles of Oncorhynchus mykiss trout at seven production centers in the province of Yauli, Junín-Peru. The determination and quantification of total heavy metals in water samples collected monthly from the production sites and in 28 trout that averaged 250 g and 27 cm was performed by atomic absorption spectrophotometry, according to the methodology recommended by FAO. Levels of Zn, Fe and Pb were found to exceed the environmental quality standards established by the Peruvian Ministry of the Environment for the rivers of the coast and highlands, as well as the quality standards of the European Union for the cultivation of trout, while levels of Cu conformed with those standards. Concentration of Cu, Zn, Fe and Pb in the livers, kidneys and muscles exceeded the maximum permissible limits established by the European Union for fish meat and by the Mexican official standard, NOM-027-SSA1-1993, for fresh, refrigerated and frozen fishery products, in the case of Pb. The correlation between the concentrations of copper, zinc, iron and lead in the water and the concentrations of these metals in the livers, kidneys and muscles is low and not significant, except for copper, which had a significant correlation.

title: Methane concentration variability in Pantanal region in the Mato Grosso State using data from AQUA satellite

description: Abstract Methane emission is an important factor in the management of wet areas such as the Pantanal region. The temporal variability of CH4 concentrations on the Pantanal was therefore studied using remote sensing data from 2003 to 2013 from an AIRS sensor on board of AQUA satellite. Wetlands worldwide contribute to the overall CH4 cycle, emitting around one-third of the overall CH4. However, the dynamics of CH4 remain poorly understood in the Pantanal. This work studied the variability of CH4 in the atmosphere over the Pantanal of Mato Grosso, based on the time series of CH4 concentration (2002-2013). The methodology used was based on descriptive statistics that included weekly averages, variance anomalies, cross-correlation between precipitation and concentration of CH4, and the transformed wavelet technique. The results showed a seasonal average concentration and the variability of CH4 abnormality in a negative cross-correlation with precipitation. Sub-annual variations of CH4 were inversely related to precipitation, and seemed to be influenced by the concentration of hydroxyl [OH-] during the rainy season, which reduces the balance of CH4 emissions. The wavelet analysis found an annual and inter-annual cycle of CH4 concentration between 2009-2013.
