An analysis of natural factors of traffic accidents involving Yezo deer (Cervus nippon yesoensis) OAK
Kawata, Yukichika.
In Hokkaido, Japan, the number of Yezo deer (Cervus nippon yesoensis) has recently increased drastically, causing a large number of deer-vehicle traffic accidents. This paper examines conditions related to deer-vehicle traffic accidents by analysing the following relationships: time of accident and lunar phase; time of accidents and time of sunrise/sunset; likelihood of accidents and rainfall patterns, temperature and season (particularly snow and hunting seasons). The results suggest that the potential for deer-vehicle traffic accidents increases during hunting and non-snow seasons when there is little or no rainfall, just before sunrise or just after sunset, or during a full, first quarter, or third quarter moon. A statistically significant relationship...

Application of a microbial source tracking based on bacterial and chemical markers in headwater and coastal catchments ArchiMer
Jarde, Emilie; Jeanneau, Laurent; Harrault, Loic; Quenot, Emmanuelle; Solecki, Olivia; Petitjean, Patrice; Lozach, Solen; Cheve, Julien; Gourmelon, Michele.
This study identified sources of fecal contamination in three different French headwater and coastal catchments (the Justiçou, Pen an Traon, and La Fresnaye) using a combination of microbial source tracking tools. The tools included bacterial markers (three host-associated Bacteroidales) and chemical markers (six fecal stanols), which were monitored monthly over one or two years in addition to fecal indicator bacteria. 168 of the 240 freshwater and marine water samples had Escherichia coli (E. coli) or enterococci concentrations higher than “excellent” European water quality threshold. In the three catchments, the results suggested that the fecal contamination appeared to be primarily from an animal origin and particularly from a bovine origin in 52%...

Apport des données TRMM 3B42 à l'étude des précipitations au Mato Grosso. Repositório Alice
ARVOR, D.; DUBREUIL, V.; RONCHAIL, J.; SIMÕES, M..
En région tropicale, où les précipitations sont principalement d'origines convectives et où les réseaux d'observations au sol présentent de nombreuses lacunes, les données satellitaires TRMM (Tropical Rainfall Measuring Mission) représentent une alternative efficace pour l'étude de la variabilité spatiotemporelle des précipitations. Celle-ci est abordée au moyen d'une analyse en composantes principales des données TRMM 3B42 (au pas de temps mensuel) de 1998 à 2006 qui permet de mettre en évidence la variabilité saisonnière et interannuelle des pluies du Mato Grosso (Brésil), situé au sud du bassin amazonien. Les produits TRMM 3B42 sont ensuite validés à partir d'indices statistiques pour permettre de définir une résolution temporelle optimale qui autorise...

Are Brazil nut populations threatened by fruit harvest? Repositório Alice
BERTWELL, T. D.; KAINER, K. A.; CROPPER JUNIOR, W. P.; STAUDHAMMER, C. L.; WADT, L. H. de O..
Harvest of Brazil nuts from the large, iconic tree Bertholletia excelsa generates substantial income for smallholders, providing a strong incentive to conserve the mature forests where it grows. Although much previous work has focused on the impact of nut harvest on new seedling recruits into B. excelsa populations, the connection between harvest rates and long-term population stability is still unclear. Moreover, there is additional uncertainty for Brazil nut management in terms of population response to climate change and other anthropogenic influences. We drew on 14 years of research in two sites in Acre, Brazil with different B. excelsa nut harvest intensities (39% and 81%), to produce stochastic and deterministic matrix population models which...

Assessing the Impact of Changing Climate on Crop Water Requirements in Nigeria. CIGR Journal
Ilesanmi, Oluwaseun Ayodele.
Climate change is a phenomenon most of the world is recently coming to terms with but unfortunately, the African region is yet to fully understand and prepare for its effects. The change is predicted to herald positive results likewise potentially severe consequences for global food security. This study aims to improve the understanding of the impact these changes being experienced in the Nigerian climate system will have on Crop Water Requirements (CWR) for optimal productivity. Five statistically downscaled and bias-corrected Global Climate Models (GCMs): CCCMA, NOAA, MIROC, ICHEC, and NCC were applied in the estimation of CWR through the period 1985–2100 under the Representative Concentration Pathway RCP8.5. These were used to produce values of crop...

Characterization of water availability in a hydrographic basin REA
Arai,Fabiane K.; Pereira,Silvio B.; Gonçalves,Geula G. G..
The quantitative knowledge of hydrological parameters (rainfall and flow) and their spatial and temporal variability on the regions or basins should be understood as essential to the efficient planning and management of water resources. Because the Ivinhema Basin, located in the state of Mato Grosso do Sul, Brazil, represents an important inductor on the region agricultural development, characterized as a major producer of grains and meat, it was used to characterize the hydrological study. Knowing the rainfall, flow and drainage area of each of the studied affluent, it was calculated the proportion of contribution of the affluent. To that end, it was proposed the concepts of potential and real contributions, aiming to identify the proportion of...

Climate risk in maize crop in the northeastern of Brazil based on climate change scenarios REA
Silva,Vicente de P. R. da; Campos,João H. B. da C.; Silva,Madson T..
This study evaluates the impacts of climate change on the agricultural zoning of climatic risk in maize crop cultivated in the Northeastern of Brazil, based on the Intergovernmental Panel on Climate Change (IPCC) reports. The water balance model, combined with geospatial technologies, was used to identify areas of the study region where the crops could suffer yield restrictions due to climate change. The data used in the study were the time series of rainfall with at least 30 years of daily data, crop coefficients, potential evapotranspiration and duration of the crop cycle. The scenarios of the increasing of air temperature used in the simulations were of 1.5ºC, 3ºC and 5ºC. The sowing date of maize crop from January to March appears to be less affected...

Climatic characteristics of the 2010-2016 drought in the semiarid Northeast Brazil region Anais da ABC (AABC)
MARENGO,JOSÉ A.; ALVES,LINCOLN M.; ALVALA,REGINA C.S; CUNHA,ANA PAULA; BRITO,SHEILA; MORAES,OSVALDO L.L..
ABSTRACT This study discusses the climatological aspects of the most severe drought ever recorded in the semiarid region Northeast Brazil. Droughts are recurrent in the region and while El Nino has driven some of these events others are more dependent on the tropical North Atlantic sea surface temperature fields. The drought affecting this region during the last 5 years shows an intensity and impact not seen in several decades in the regional economy and society. The analysis of this event using drought indicators as well as meteorological fields shows that since the middle 1990s to 2016, 16 out of 25 years experienced rainfall below normal. This suggests that the recent drought may have in fact started in the middle-late 1990s, with the intense droughts...

Climatic risk for potato late blight in the Andes region of Venezuela Scientia Agricola
Garcia,Beatriz Ibet Lozada; Sentelhas,Paulo Cesar; Tapia,Luciano Roberto; Sparovek,Gerd.
Potato is an important crop for Venezuelan agriculture. However, its production is highly affected by late blight (Phytophtora infestans), since weather is commonly favorable for this disease. The aim of this study was to determine the sowing dates of low climatic risk for potato late blight in the Andes region of Venezuela, with an agrometeorological disease model and geographical information system (GIS) tools. The disease model used in this study was developed by Hyre (1954) which requires daily rainfall and temperature data which were obtained from 106 weather stations, located at the States of Mérida, Táchira, and Trujillo, for a period of 31 years. Hyre's model was applied for all stations obtainig the following variables: number of disease favorable...

Climatic risk zoning for corn and palisade grass (Brachiaria brizantha cv. Marandu) cultivated in integrated crop-livestock systems in São Paulo state, Brazil. Repositório Alice
SANTOS, P. M.; PEZZOPANE, J. R. M.; MENDONCA, F. C.; BETTIOL, G. M.; EVANGELISTA, B. A.; SILVA, F. A. M. da.
Climatic risk zoning allows the identification of areas of low risk of reduced crop productivity due to climatic events. In Brazil, losses to agriculture due to climate are mainly caused by drought. The objective of this research was to determine areas of low climatic risk for corn and palisade grass cultivated in integrated crop-livestock systems in Sao Paulo state. Corn varieties characterized by a 120-day growing cycle and soil with three different water holding capacities (sandy, medium and clayey soils) were considered. A daily water balance model was used to simulate planting dates between September and December. The water requirement satisfaction index (WRSI) was calculated for critical phenological phases of both cultures (germination, emergence...

CLIMATOLOGICAL WATER BALANCE WITH DATA ESTIMATED BY TROPICAL RAINFALL MEASURING MISSION FOR THE DOCE RIVER BASIN REA
Louzada,Franciane L. R. de O.; Xavier,Alexandre C.; Pezzopane,José E. M..
ABSTRACT The Climatic Water Balance (CLIMWB) is very used in the climatic characterization and can also offer important contribution in the identification of the water demand for irrigation of a region. For this, reliable precipitation data with good spatial coverage is required. The Tropical Rainfall Measuring Mission satellite -TRMM-3B43-v7 is a partnership between NASA (National Aeronautics and Space Administration) and Japan's Aerospace Exploration Agency (JAXA), which estimates rainfall data for the tropics region. The aim of this study is to evaluate the CLIMWB obtained by the Thornthwaite & Mather method (1955), with estimated rainfall data with the 3B43 product versus those generated with rainfall data and to map pixel-by-pixel water...

Daily rainfall variability at a local scale (1,000 ha), in Piracicaba, SP, Brazil, and its implications on soil water recharge Scientia Agricola
Reichardt,K.; Angelocci,L.R.; Bacchi,O.O.S.; Pilotto,J.E..
Daily rainfall variability at a local scale (1,000 ha) was studied at Piracicaba, SP, Brazil, for the period of one year (1993-1994), in order to better understand the process of soil water recharge. Coefficients of variation of daily data for ten observation points varied from 2.2 to 169.3% and the variability was independent of rain type, i.e. whether convective, frontal or of other origin. Data were not related to separation distances between observation points and it is concluded that one observation point does not represent areas as far as 1,000 to 2,500 m apart, for daily, monthly or even quarterly averages. Yearly totals for the ten observation points presented a coefficient of variation as low as 3.06%, indicating that all points can replace each...
