Negotiations between industry, environmental partnership and government were intense, demanding, and created a high degree of confidence, candour and openness among participants. Over a three-week period, a very high level of trust was developed as vested interests were left at the door. All parties were expected to, and did, operate in an honest and forthright fashion. At the end of the process, participants were able to deliver a document built on mutual gains. Each party could honestly say they had gained from the process and not merely acquiesced to a form of consensus. The "Ontario Forest Accord" is, by any measure, a tremendous step forward for industry, government and the environmental community.

Landslide Disaster

Jember regency has several areas that are morphology of folding hills and mountain folds. The part of landslide prone zone is closely related to the slope of the slope. Areas with a sloping slope of more than 15º need attention to the possibility of a landslide disaster. Interconnection contacts with weathering of rocks, settlements and land cover also affect the landslide potential. The existence of Ijen Volcano that produces volcanic rock deposits that are generally not yet unified will increase the potential for landslides in Jember Regency. Landslide has occurred one of them on Gunung Gumitir Street which is the main route of Surabaya-Jember-Banyuwangi traffic. In May 2016 this street is hit by landslide, so the flow of traffic through this lane is paralyzed and must be diverted to a further path, which rotates to Situbondo City. The transfer of this pathway resulted in a loss to the local community and who crossed the path.The occurrence of landslide disaster shows that Jember Regency area is vulnerable and potentially return to landslide. Therefore there is a need for a solution to solve this problem. One solution to solve the problem is by utilizing Geographic Information System (GIS) application. The purpose of this research is to analyze zonation prone to landslide in jember district. The design of the research is Geographic Information System overlay analysis. This design combines several parameters in the determination of landslide-prone zones. This design combines several parameters in the determination of landslide-prone zones. The parameter used in this research is (1) land use, (2) topography, and (3) soil.Based on the research results, it can be known zone with highest to lowest vulnerability level. Zone with very high level of vulnerability is located in Panti sub-district, Sumberbaru, Sukorambi, Dyke, Silo and Jelbuk. The zones have similar characteristics that include (1) soil type of andosol, (2) clay texture, (3) uncompacted rock, (4) slope of 30⁰-40⁰ (steep and very steep), and (5) land use for settlements and plantations.

Este trabalho objetivou avaliar o potencial pedoclimático do Estado da Paraíba para a cultura agrícola do algodão herbáceo. Na obtenção dos mapas de potencial pedoclimático, as informações obtidas do potencial dos solos foram cruzadas com aquelas da aptidão climática considerando três cenários pluviométricos: anos chuvosos, anos regulares e anos secos. O cruzamento das informações foi realizado por meio de técnicas de geoprocessamento utilizando o software SPRING e obtendo-se os mapas do potencial pedoclimático. O resultado das interpretações foi classificado em quatro classes: Muito Alto, Alto, Médio, Baixo e Muito Baixo. Os resultados demonstraram que a variabilidade pedológica e climática do Estado da Paraíba tem influenciado o potencial pedoclimático do Estado para a cultura do algodão herbáceo, tendo sido observadas diferenças significativas na extensão territorial das classes e subclasses de potencial pedoclimático. A extensão do potencial pedoclimático Alto e Médio apresentou significativo aumento em relação aos cenários seco e regular, com maior percentual de ocorrência para o cenário pluviométrico chuvoso. Não houve dados para a classe de potencial pedoclimático Muito Alto e dessa forma a mesma não foi mapeada neste trabalho. A área da classe Alta aumenta conforme cresce o cenário pluviométrico. A classe Média do potencial pedoclimático é ampliada em área conforme aumenta a probabilidade de chuvas. Na classe Baixa de potencial pedoclimático a diferença na mudança foi pouco significativa. Entre as subclasses do potencial Muito Baixo, foi observado aumento da área de acordo com o aumento da probabilidade de ocorrência de chuvas no Estado.    A B S T R A C T The objective of this work was to evaluate the soil and climate potential for upland cotton in Paraiba state, Brazil. For obtaining pedoclimatic potential maps, the information obtained for soil potential were combined with that to climate ability considering three rainfall scenarios: wet years, dry years and regular years. Information crossing was carried out by techniques of geoprocessing using the SPRING software and maps of soil and climate potential were obtained. The interpretation results were classified into four pedoclimatic potential classes: Very High, High, Medium, Low and Very Low. The results showed that pedological and climate variability in Paraiba state have influenced the pedoclimatic potential of this state to the upland cotton, with significant differences observed in the territory for classes and subclasses of pedoclimatic potential. The extent of potential soil and climate High and Medium showed a significant increase over the dry and regular scenarios, with the highest percentage of occurrence for the rainy rainfall scenario. There was no data for the potential class Very High soil and climate and therefore the same has not been mapped in this work. High class area enlarges as the rainfall scenario increases. The mapped area for the Middle class showed enlargement with rainy probability increases. Little significant changes were observed for Low class of soil and climate potential. Among potential subclasses Very Low, were observed an area increase according rain probability was enlarging in the state.

La Conca de Tremp, situada en la comarca montañosa catalana del Pallars Jussá, es una de las áreas donde más se ha incrementado la ganadería porcina en régimen estabulado en las últimas tres décadas. Los impactos medioambientales negativos derivados de este sistema de producción ganadera son muy considerables, especialmente los relacionados con el vertido de puriñes que ha provocado un alto grado de nitrificación de las aguas. Análisis pormenorizados demuestran que el nivel de nitrificación de las aguas en la Conca de Tremp ha alcanzado un nivel muy alto, con las consecuencias que ello tiene en la salud de las personas. Atendiendo a las exigencias del desarrollo sostenible, única forma de garantizar el futuro de las comarcas de montaña, se apuntan soluciones para paliar los graves problemas generados por la intensificación de la ganadería porcina.The Tremp Basin, placed in the mountainous Catalonian region of the Pallars Jussá, is one of the areas where stabled pig cattle raising has been more increased in the last three decades. Negative environmental impacts, derived from this cattle raising production system are greatly substantial, specially the ones related to purine wastes which have caused a high degree of nitrification of the waters. Detailed analyses show that the degree of nitrification of the waters in the Tremp Basin has reached a very high level, with all that this implies for human health. Attending to the requirements of a sustainable development, which is the only way of granting a future for the mountainous regions, this paper hints at some solutions to lessen the serious problems generated by the intensification ofpig cattle raising.

Flow metering of industrial fluids remains the concern of several researchers and exporting countries of gas and oil in the world. It is in this context that a vast numerical investigation is done in our laboratory of Industrial Fluids Measurements and Applications (FIMA). This article examines numerically a new design of the Etoile flow straightener which is described by the standard ISO 5167. This new design consists in removing the central part of the Etoile which, according to researchers, leads to a very high level of turbulence. Our intervention relates to the development and the establishment of the flow parameters downstream the Etoile with and without central part. The flow is produced by air in a 100mm pipe diameter and 40D of length with a Reynolds number of 2.5×105. The disturbance is a valve maintained 100%, 50% and 30% open. The flow parameters examined are velocity profile, turbulence intensity profile, and the fluid gyration angle. The code CFD Fluent is used for this simulation. The results obtained are compared according to directives of the standard ISO 5167. The results obtained show that for the valve settings 30% and 50% open, upstream the Etoile, we have a high turbulence level and a velocity profile with recirculation zones more significant for the valve 30% open than for the valve 50% open. It is also noted that the valve develop very high fluid gyration angle apart from the standard values. The flow behavior downstream the central part of Etoile described by the ISO 5167 is well simulated with the valve open at 100%, with a deficit of flow and a very high degree of turbulence. At this stage for the two designs, the noticed results seem so identical beyond a certain stations downstream the Etoile.

Pacitan is one of the regencies in East Java Province, dominated by hills and mountain landforms covering 85% of its area. Since 2011, more than 16 landslides have occurred significantly in this area. These disasters have engulfed more than 350 ha of agricultural land in Pacitan. This study analyzed the risk of future landslides due to land use change. The parameters used were rainfall, slope, topography, geology, soil, and land use which were assessed and weighed by the Paimin method. Land-use classification from Landsat 8 OLI in 1998, 2008, and 2018 were analyzed using regression formula to calculate the trend of change in 2030. Land use was also classified from the land capability classification (LCC) and regional spatial planning (RSP) as land use options in 2030. The results showed that land use changed over time due to the changes in landslide hazards, which increased three-foldfrom 1998 to 2018 and will peak tremendously in 2030. There are 29.47 ha of agricultural land in 2018 that have a high potential landslide hazard if no intervention is made. The accuracy for prediction of the 2018 data mapping was 82%. The LCC strategy suggests land use planning to reduce a high level of the landslides.

Um instrumento utilizado no planejamento ambiental de bacias hidrográficas é o zoneamento (geo)ambiental, principalmente no que diz respeito à expansão urbana. Nesse contexto, o trabalho teve como objetivo a elaboração da carta de potencial de contaminação de aquíferos para a bacia hidrográfica do Ribeirão das Pedras (São Paulo, Brasil), na escala de 1:50.000. Esta bacia estende-se por 111,47km2, tendo a maior parte de sua área contida no município de Santa Cruz das Palmeiras e algumas parcelas menores nos municípios de Tambaú, Pirassununga e Porto Ferreira. Para a elaboração deste documento cartográfico foram adotados os seguintes procedimentos: delimitação da bacia a partir da articulação de cartas topográficas no software de Sistema de Informação Geográfica (SIG) ArcGis® 10.3; elaboração da carta de formações geológicas da bacia e a classificação do potencial de contaminação, por meio de uma análise multicritério, envolvendo cinco classes: muito baixo, baixo, médio, alto e muito alto.  Como resultado, obteve-se a carta de potencial de contaminação, na qual as classes “alto” e “muito alto” potencial somam 36,31% da área, onde as unidades aquíferas têm grande capacidade de fluxo e armazenamento, os potenciais baixo e muito baixo, se localizam nas unidades aquíferas Intrusivas Básicas e Aquicludo Corumbataí, com características que limitam a capacidade de percolação e armazenamento de água. O potencial “médio” teve influência positiva da maioria dos atributos (unidades aquíferas, materiais inconsolidados, declividades e formas do terreno), sendo que o único atributo que contribuiu de forma negativa é o uso da terra, devido às práticas agrícolas. O documento pode contribuir para um melhor ordenamento do território respeitando o meio físico e sua capacidade de suporte, de forma a colaborar para gestão da BHRP.  Anthropic Activities in Ribeirão das Pedras Drainage Basin, São Paulo State, Brazil A B S T R A C TGeoenvironmental zoning is an instrument widely used in the environmental planning of river basins, especially with regard to urban expansion. In this context, the objective of this study was to prepare a 1:50,000-scale chart of the contamination potential of aquifers for the Ribeirão das Pedras watershed, located in Sao Paulo state, Brazil. This river basin comprises an area of 111.47 km2, most of it located in the municipality of Santa Cruz das Palmeiras, with some smaller portions in the municipalities of Tambau, Pirassununga, and Porto Ferreira. The following procedures were conducted for the preparation of this cartographic document: delimitation of the catchment area based on the articulation of topographic charts using the Geographic Information System (SIG) ArcGis® 10.3 software; preparation of a map of geological formations of the basin; and classification of the contamination potential by multicriteria analysis including five classes: very low, low, medium, high, and very high. As a result, a chart of contamination potential was produced showing that the high and very high potential classes comprised 36.31% of the catchment area, where the aquifer units present high water flow and storage capacity; the low and very low potentials are located on the Basic Intrusive and Corumbatai aquifer units, with characteristics that limit the capacity of water percolation and storage; and the medium potential positively influenced most of the attributes (aquifer units, uncontaminated materials, slopes, and geological formations), with land use due to agricultural practices as the only attribute with negative contribution. With this information, it is possible to develop a better land use planning, respecting the physical environment and its support capacity in order to collaborate to the management of this water source.Keywords: Geoenvironmental zoning; Multi-criteria analysis; Aquifer units; Land use planning.

Air traffic controllers use a radar separation minimum when keeping aircraft safely apart. The choice of minimum needs to ensure, to a very high degree of confidence, that radar inaccuracies are not putting the aircraft into a risk of collision – controllers can of course be required to use larger minima for operational reasons. A particular separation minimum necessarily feeds back into requirements on radar design criteria, data processing and performance. The estimation of the radar separation minimum is significantly improved by the use of a new methodology. Previous derivations were a major step forward, but were ‘static’, in that they did not attempt to take properly into account how controllers use separation minima dynamically. An analysis on the use of separation minima in en route airspace by controllers concludes that they are generally likely to use the radar minimum to pass aircraft, rather than to use the minimum in a ‘strategic’ sense (e.g. ‘in trail’ separation). The new ‘Event Model’ methodology recognises that collisions cannot happen instantly: the aircraft pair concerned must move from a safe configuration to a hazardous one. Collisions are therefore events caused by flawed flight paths, dependent on both the initial positions of aircraft and their subsequent movements and velocities.

The Impact

Land use change, especially that due to farmland abandonment in the mountains of Nepal, is being seen as a major factor contributing to increasing eco-environmental risk, undesirable changes in the socio-cultural landscape, biodiversity loss, and reduced capacity of the ecosystem to provide key services. This study aims to: i) evaluate eco-environmental risk for one of the high mountain river basins, the Dordi river basin in Nepal, that has a growing potential of farmland abandonment; and ii) develop a risk-based land use planning framework for mitigating the impact of risk and for enhancing sustainable management practices in mountain regions. We employed a multi-criteria analytic hierarchy process (AHP) to assign risk weightage to geophysical and socio-demographic factors, and performed spatial superposition analysis in the model builder of a geographic information system (GIS) to produce an eco-environmental risk map, which was subjected to a reliability check against existing eco-environmental conditions by ground truthing and using statistical models. The result shows that 22.36% of the basin area has a high level of risk. The very high, extreme high, moderate, and low zones accounted 17.38%, 7.93%, 28.49%, and 23.81%, respectively. A high level of eco-environmental risk occurs mostly in the north and northwest, but appears in patches in the south as well, whereas the level of moderate risk is concentrated in the southern parts of the river basin. All the land use types, notably, forest, grassland, shrub land, and cultivated farmland, are currently under stress, which generally increases with elevation towards the north but is also concentrated along the road network and river buffer zones where human interference with nature is the maximum. The risk map and the framework are expected to provide information and a scientific evidence-base for formulating and reasonable development strategies and guidelines for consensus-based utilization and protection of eco-environmental resources in the river basin. As an awareness raising tool, it also can activate social processes enabling communities to design for and mitigate the consequences of hazardous events. Moreover, this risk assessment allows an important link in understanding regional eco-environmental risk situation, land use, natural resources, and environmental management.

Abstract Channel dynamics is an inherent characteristic of the river in the floodplain region. The river bankline shifting and associate land use land cover (LULC) change is not only geomorphological but also an environmentally vital hazardous issue. It is a significant impact on the ecosystem and human life. GIS-based, DSAS and CA-Markov models are efficient to accurately measure historical and predictionevaluation of the relation between channel shifting and LULC change. In this study, forty-eight years (1972-2020) of earth observatory data have been used to demarcate the channel bank position and LULC change detection along the Kaljani River at the eastern Himalayan foothill. During 1998-2008, very high erosion rate on both bankline, which are about -4.48 m/y and -3.48 m/y at the left and right, respectively compared the others time frame. The overall result of the predicted bankline represents that the bulky expansion will occur along the left bank and sediment accretion will take place at the right bank. Among the three zones, both banks of zone ‘A’ (lower part of the river) is the worst affected part in the past, present, and future time. The LULC change of all six classes from 1972 to 1998 was very high when compared with the change between 1998 and 2020. Moreover, the long profile, hypsometric curve value, and the Soil Conservation Service Curve Number (SCS-CN) value have been a significant help in understanding and identification of consequences reasons. The level of accuracy is validated by the observed bankline positions (2020) with predicted bankline (2020) and observed LULC (2020) to predicted LULC (2020) empirically with RMSE and statistical test. Therefore, the output of the prediction not only serves as the spatial guidelines for monitoring future trends of channel shifting and land use planning management.
