Asiatic palm weevil Rhynchophorus vulneratus Panzer is one of the key pests coconut in Indonesia. Information regarding spatial distribution R. needed to support Integrated Pest Management and can be analyzed using Geographic System (GIS). Initial studies on interaction between Oryctes rhinoceros were also studied this study. This research aimed analyze GIS its with Coconut beetle rhinoceros. T...

The amount of rainfall that occurs can affect natural disasters and even food production to economic activities. the factor area where rain is one main parameters for how change occurs. So, it necessary have a prediction approach aims find out when what type will occur. Spatial classification interpolation are two methods used make predictions. Random Forest method be predict rainfall. Inverse ...

In this study, a regionalization study was conducted with the L–Moments method in order to determine change of dissolved oxygen (DO) required sustain life aquatic organisms given return period and also consider effects all stations. Dissolved concentration data 20 meteorological stations for spring months were evaluated between 1995 2014 Sakarya Basin, Turkey. Firstly, Homogeneity Criterion (H1...

Spatial and temporal variability analysis of precipitation is an important task in water resources planning and management. This study aims to analyze the spatial and temporal variability of precipitation in the northeastern corner of Iran using data from 24 well-distributed weather stations between 1991 and 2015. The mean annual rainfall, precipitation concentration index (PCI), and their coef...

The Multicriteria Decision Analysis (MCDA) and Geographical Information Systems (GIS) are used to provide more accurate decisions to the decision makers in order to evaluate the effective factors in the natural science. One of the popular algorithm of multicriteria analysis is Ordered Weighted Averaging (OWA). The OWA procedure depends on some parameters, which can be 15 specified by means of f...

Toxoplasmosis is a protozoan disease that is caused by Toxoplasma gondii in livestock and humans. Due to its medical and veterinary importance, it is essential to study the seroprevalence of T. gondii infection among humans and animals in various parts of the world. The major objective of this study was to determine the seroprevalence and spatial distribution of toxoplasmosis in small ruminants...

It is challenging to perform spatial geochemical modelling due to the spatial heterogeneity features of geochemical variables. Meanwhile, high quality geochemical maps are needed for better environmental management. Soil organic C (SOC) distribution maps are required for improvements in soil management and for the estimation of C stocks at regional scales. This study investigates the use of a g...

In this study, a spatiotemporal estimation method based on Funk singular value decomposition (F-SVD) that considers the correlation of rainfall is proposed to improve estimations from gauge observations. Hourly data several flood events are selected verify by comparing with Inverse Distance Weighting (IDW) and Ordinary Kriging (OK) in Hanjiang basin, China. The results show (1) F-SVD has best p...

Abstract An accurate analysis of spatial rainfall distribution is great importance for managing watershed water resources, in addition to giving support meteorological studies and agricultural planning. This work compares the performance two interpolation methods: Inverse distance weighted (IDW) Kriging, annual distribution. We use data state Rio Grande do Sul (Brazil) from 1961 2017. To determ...
