Ammonia Concentrations and Emissions from Finishing Pigs Reared in Different Growing Rooms
Authors: Costa Annamaria 
Published: January 2017

Even with the adoption of Best Available Techniques (BAT) standards, pig producers have observed different degrees of fouling on the floor during the finishing phase. These differences depend on the excretory behavior of pigs reared in different growing facilities. Our objectives in this study were to measure ammonia (NH3) concentrations and emissions from finishing pigs reared in different growing rooms and subsequently housed in identical BAT room types. The 1600 pigs used in the study were reared in growing rooms with a slatted floor and a vacuum system for manure removal (WSF) or in growing rooms with a solid floor and an outside alley and storage pit (WCF). Pigs were grouped by type of growing room and allocated to two WCF finishing rooms per group. Mean NH3concentration (7.45 vs. 5.31 mg m−3) and degree of fouling on the floor (77 vs. 37%) were significantly greater (P< 0.001) in the WSF compared with the WCF finishing rooms. Pigs in the WCF emitted 4.63 g NH3pig−1during the measurement period, whereas those in the WSF emitted 6.55 g NH3pig−1. Our results indicate that, because pigs’ fouling behavior is established during the growing phase, the finishing phase should be performed in a similar facility designed to maintain the NH3reduction provided by BAT systems. In this study, growers housed in a WSF facility exhibited the same defecating and urinating habits when moved to the WCF facility despite the availability of an outside alley. This management choice limited the capability to lower NH3concentrations and emissions, negatively affecting animal performance.Core IdeasTwo groups of 800 fattening pigs were housed in different BAT weaning facilities.Weaners were reared either on slats or on full floor with external area.Floors were fouled by 35% in WCF and by 70% in WSF weaning rooms.With fatteners reared in WCF houses, fouling degree was 37% (WCF) and 77% (WSF).Ammonia concentration and emission was higher for WSF fatteners.
Chemical Composition of Soil Organic Matter in a Subarctic Peatland: Influence of Shifting Vegetation Communities

Published: January 2017

Core IdeasSoil organic matter chemical composition highlighted the inputs of varied vegetation communities in the past.Soil N is an indicator of peat decomposition based on relationship of functional group C and total N.Future surveys of soil organic matter biogeochemical parameters and C chemical composition should be pursued.Climate change in the subarctic region has increased the rate of inundation of peatlands due to increased temperatures, precipitation, and permafrost thaw. Increased inundation may result in vegetation community shifts, as documented in a subarctic mire near Abisko, Sweden. The wet fen communities have established in former sphagnum areas, and sphagnum colonized in degraded palsa hummocks. At Stordalen mire, we studied the influence of vegetation community on chemical composition of peat soil organic matter (SOM). Vegetation and soil samples were obtained along a hydrologic gradient with representative communities: palsa, sphagnum, and fen. Soil organic matter chemical composition indicated shifts in vegetative communities. Total N and N isotope signatures in fen soils showed characteristics of sphagnum and palsa communities at >6‐cm depth, and sphagnum soil profile signatures shifted from sphagnum to palsa properties at a 20‐cm depth. Soil chemical composition measured by Fourier Transform Infrared (FTIR) spectroscopy and13C Nuclear Magnetic Resonance (NMR) spectroscopy showed increasing recalcitrant C (alkyl and aromatic) in palsa soil. Sphagnum soil profiles sustained labile organic C (O‐alkyl) until 15 cm then shifted to humified soil, and fen soil profiles showed areas of sphagnum and palsa signatures. Furthermore, the strong relationship between functional group C (O‐alkyl and alkyl) and total N demonstrated that soil N is an effective indicator of peat decomposition. Our results identified change points in soil chemical composition in regards to N content and C functional group which highlights the importance of historic vegetation community on chemical composition of peat soils.

Borde costero resiliente: aprendizaje post-27F para el norte grande de Chile
Authors: Intveen Pérez Hans P. 
Published: January 2017

Resumen: Con posterioridad al terremoto y tsunami de 2010 en Chile, se ha evidenciado que los espacios residuales que el crecimiento urbano no planificado de las ciudades ha dejado en el paisaje costero, se han transformado en la primera línea de defensa contra los eventos naturales catastróficos, al tener una relación directa con las unidades de paisaje donde se produce la mayor destrucción. El proceso de reconstrucción, posterior al desastre, ha permitido incorporar nuevos conceptos a la planificación del paisaje costero, lo que ha generado una experiencia y un caudal de conocimiento que permiten extraer principios de diseño urbano que pueden replicarse en otras geografías vulnerables, como el caso del Norte Grande en Chile. La investigación plantea una sistematización de principios generales de ordenamiento espacial para espacios costeros en el contexto de paisaje nortino, de una manera que permita no solo la resistencia al evento, sino su eficiente reconstrucción y rápida adaptación a circunstancias adversas.
___Palabras clave: Mitigación, resiliencia, borde costero, paisaje urbano.
___Abstract: Following the earthquake and tsunami of 2010 in Chile, it has become evident that the residual spaces that unplanned urban growth of the cities has left in the coastal landscape have become the first line of defense against catastrophic natural events, since they have a direct relationship with the landscape units where the greatest destruction occurs. The post-disaster reconstruction process has allowed the incorporation of new concepts into coastal landscape planning, which has generated an experience and a wealth of knowledge that allow the extraction of principles of urban design that can be replicated in other vulnerable geographies, such as the case of the Great North in Chile. The research proposes a systematization of general spatial planning principles for coastal spaces in the context of the northern landscape, in a way that allows not only the resistance to the event, but also its efficient reconstruction and rapid adaptation to adverse circumstances.

Embalses de retención y canales verdes: herramientas para el control de inundaciones y la planificación urbana. Caso de estudio: municipio de Turbaco, Bolívar
Authors: Guerrero Pájaro Milton 
Published: January 2017

Resumen: La rapidez en el crecimiento de nuestras ciudades y municipios, y el aumento vertiginoso en la demanda de suelo urbanizable, ha originado la impermeabilización del suelo urbanizado, lo que ha producido un aumento en los caudales de escorrentía. Por otro lado, el cambio climático impone nuevos desafíos en materia de gestión del drenaje pluvial para nuestras ciudades y municipios. El municipio de Turbaco vive una problemática en materia de drenaje pluvial, por causa del aumento en la demanda de suelo urbanizable y por la impermeabilización del suelo urbanizado. Los embalses de retención y las canales verdes surgen como una alternativa para la gestión de las aguas pluviales. Estos sistemas son de fácil adaptación al medio y son soluciones que van en favor del medio ambiente, al tiempo que constituyen parte del paisaje urbano.
___Palabras clave: Inundaciones, embalses, canales verdes, análisis hidrológico, planificación urbana.
___Abstract: The rapid growth of our cities and municipalities, and the rapid increase in the demand for urbanizable land, has led to the waterproofing of urbanized land, which has led to an increase in runoff flows. On the other hand, climate change imposes new challenges in the management of storm drainage for our cities and municipalities. The municipality of Turbaco lives a problem in the matter of rainwater drainage, due to the increase in the demand of urbanizable land and the waterproofing of the urbanized land. Retention reservoirs and green channels emerge as an alternative to stormwater management. These systems are easy to adapt to the environment and are solutions that are in favor of the environment, while being part of the urban landscape.
