The main objective of this paper consist to discuss the relationship between poultry producers and their integrators in West region of Paraná, capturing poultry producer’s perception and theirs decisions for choosing and staying in an integration contract. A sample of 98 producers were interviewed and non-parametric statistical tests were used, including cross-reference tables, comparison proportions tests and bivariate correlations. Results indicate that producer profiles are mainly constituted by small or medium enterprises with a high dependence degree on agro-industry. An intense competition exists and mostly, producers choose an integrator based on brand trustworthiness and not according to prices offered, explained by the high specificity of production relationship.

The paper aims at adapting the knowledge regarding the capitalization of tourist resources to the method of tourist choremas in the Oltenia region, Romania, thus creating a tool for planning and organizing the geographical space for sustainable development. The tourism choremas method uses the graphic and cartographic modelling of the territory of the South-West Oltenia region, and in a post-COVID-19 period it is important that the research can help in increasing the productivity in tourism, which can lead to higher incomes for managers in the tourism sector and for the locals from different rural/disadvantaged area of the region. GIS (Geographical Information Systems) represents a key element for the future development of tourism in the virtual environment, given the fact that many travellers use virtual electronic systems to see the tourist destination, surroundings, protected areas, accommodation, tourist routes, recreation and entertainment areas (zoos, hunting areas), etc. Chor...

Air pollution has numerous detrimental consequences for human health, visibility, climate, materials, plant health, and animal health. A portion of air pollution consists of metals, which are emitted into the environment via the combustion of fossil fuels, industrial activities, and the incineration of metal-containing products. In this work, the particulate matter and particle-related metal pollution from various sources, in the Turkish province of Kayseri, were determined. AERMOD modeling was also used to examine the distribution of PM10 around the Kayseri Organized Industrial Zone (OIZ). Particulate matter (PM10) samples were collected using MCZ dust collecting devices at six monitoring locations mainly affected by residential heating (Hürriyet, Talas, and Kocasinan), industry (OIZ), and traffic (Tramway and Cumhuriyet) during the autumn/winter months and at three monitoring locations mainly affected by residential heating (Kocasinan), industry (OIZ), and traffic (Tramvay) during...

The flood hazard risks and vulnerability in the urban areas alongside major rivers of India have been gradually increasing due to extreme climatic events. The present study is intended to assess flood hazard vulnerability and potential risk areas and aims to ascertain the management strategies in Nabadwip Municipality, a statutory urban area of West Bengal. The multi-criteria decision making (MCDM) of selected criteria and geospatial techniques have been employed to determine the urban flood vulnerability in the study area. The study has been conducted using secondary datasets including relevant remotely sensed data and participant observation. The potential flood-affected zones have been determined using the normalized difference flood index (NDFI) and flood vulnerability index (FVI). The analysis of the standardized precipitation index (SPI) of 20 years of monthly precipitation shows the variability of seasonal rainfall distribution in the study area. Furthermore, the spatial dist...

Dams are infrastructural projects with multiple uses that include hydropower, irrigation, water storage, flood management, and recreation. Most research on dams in Southeast Asia focuses on the Mekong River Basin and there is limited research on dams in Indonesia. Here, we developed a comprehensive database of dams in Indonesia derived from global and local datasets. We also used Google Earth Pro to locate additional dams and to validate the presence of all the dams. Our database had a total of 1506 dams (from large to mini dams and run-of river dams) in operation or under construction, and this was three times the number of dams reported in Indonesia’s national database for dams. There were another 250 planned dams, of which, only 30 had known locations. Our database also includes information such as the geographical coordinates of each dam, their physical characteristics, and what each dam is used for. Ultimately, we hope that our work will help researchers, non-government organiz...

The impacts of Climate Change are quite visible in Guinea-Bissau. Greater irregularity at the beginning and end of the rainy season, as well as in relation to the interannual variability of precipitation, are evidence that shows these phenomena in West African countries and particularly in Guinea-Bissau, where the agriculture is rain-fed. The year 2020 was characterized as very rainy in comparison to the climatological average of 1981–2020, with positive anomalies throughout the country, despite the late arrival of the wet season, which usually occurs in May. July, August, and September 2020 were the rainiest months, registering above a normal frequency of days with precipitation greater than 50 mm. Bissau, the capital, registered a record-breaking annual rainfall and monthly amounts higher than the 90th and 95th percentiles in July and August, respectively. This heavy rain accompanied by strong winds caused flooding in several urban areas and agricultural fields, and the destructio...

2020 was the start of the toughest year for the world community in general, especially Indonesia in the health sector. The outbreak of the Covid-19 case in various regions requires clear and accurate information in efforts to deal with this pandemic. This study aims to spatially map the vulnerability of COVID-19 based on Geographic Information Systems (GIS). The method d used is a weighted overlay. The data used are population (P), population density (PD), elderly (EP), school students (SS), and hospital beds (HB). The analysis s used is a spatial analysis using ArcGIS 10.8. The results of the study show that North Pontianak District has a very high vulnerability to COVID-19. West Pontianak District and Pontianak City have high vulnerability. South and East Pontianak sub-districts have moderate vulnerability. For Pontianak Tenggara District, the level of vulnerability to COVID-19 is very low. The vulnerability to COVID is very low in Southeast Pontianak District because it has the s...

We examine the coseismic influence of the 5 July 2019, MW7.1 Ridgecrest and the 24 June 2020 MW5.8 Owens Lake earthquakes on rockfall distributions in two undisturbed high-altitude areas of the southern Sierra Nevada Mountains, California, USA. These events occurred within the geologically recent (<2 Mya) Walker Lane/eastern California shear zone. While both study areas are characterized as plutonic, the Owens Lake event largely affected terrain that was formerly glaciated and oversteepened while the Ridgecrest event affected non-glaciated terrain. Our inventory of rockfall locations was derived from analysis of Sentinel-2 images acquired just prior to and immediately after the events. This difference mapping approach using readily-available Sentinel-2 imagery allows for rapid rockfall and landslide mapping. GIS analysis shows that even though the total area assessed for both earthquakes was similar (~1500 km2), the significantly lower magnitude Owens Lake event produced nearly t...

Energies

This article evaluated bioelectricity’s evolving competitiveness and systemic complementarity benefits, both in comparison with other renewable sources. To do so, the results of several energy auctions were analysed, and a modelling exercise was developed using an optimisation model based on stochastic dual dynamic programming. The results indicate that wind and solar energies became the least cost expansions, and sugarcane bioelectricity lost significance and competitiveness in this environment. At the same time, the study shows that wind power’s potential to be complementary to hydropower generation is greater than bioenergy in Brazil. These findings have relevant policy implications regarding the power sector and whether bioelectricity from sugarcane should still be incentivised along with wind power sources. It is worthwhile to point out that although the Brazilian case is explored in the article, it can be used as an example by other countries, especially developing ones, that ...
