Assessing village food needs following a natural disaster in Papua New Guinea

Papua New Guinea is vulnerable to natural disasters, including drought and frost associated with El Niño weather events and excessive rainfall associated with La Niña events. Drought, frost and excessive rainfall can cause major disruptions to village food supplies. Drought also reduces villagers’ access to clean drinking water, which in turn has a negative impact on peoples’ health and the capacity of schools and hospitals to operate. There are often other impacts — damage to crops and property by wildfires, out-migration and an increased death rate. In 1997–98, and again in 2015–16, a major El Niño event caused significant disruption to drinking water and food supply for many Papua New Guinean villagers. Staff of many agencies, including those working through the Church Partnership Program El Niño Drought Response Program, were involved in assessing the impact and providing relief in 2015–16. This publication brings together the experiences of those working on the Church Partnership Program response to the 2015–16 El Niño event and serves as a guide for assessing future food shortages and to help those in need.Australian Government Department of Foreign Affairs and Trade (DFAT

Pacific Island food security: situation, challenges and opportunities

In recent years, there have been large and rapid increases in the prices of basic foods worldwide. Pacific island countries have not been isolated from the global food 'crisis'. This article shows that there are substantial differences in the impacts within and between Pacific island countries. To be effective and not counterproductive, policy and donor responses need to be tailored accordingly. This article recommends a combination of measures directed at mitigating the threats and empowering rural people to take advantage of the opportunities

Full scale study of chemically enhanced primary treatment in Riviera de Sao Lourenco, Brazil

Thesis (M.Eng.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 2000.Includes bibliographical references (leaves 148-149).Effective, low-cost wastewater treatment that permits removal of pollutants and the deactivation of pathogens is essential to protect public health. An emerging technology that has been proposed to accomplish this goal, is Chemically Enhanced Primary Treatment, or CEPT. CEPT vastly improves the effectiveness of an existing wastewater treatment facility, enabling the plant to not only meet increasing flow demands, but to attain higher removal efficiencies at the same time. Similarly, in the case of a new treatment facility, it can be designed to treat larger amounts of flow, and/or the designed size can be decreased by as much as half, and still meet expected capacity. The governing principle behind CEPT is the enhancement of the primary settling process through the addition of low dosages of metal salts and extremely small amounts of an anionic polymer. These additions cause the particulate matter in the wastewater to coagulate and flocculate, thus creating larger particles, which in turn settle at a much faster rate. This thesis looks at the different forms by which CEPT can be implemented in wastewater lagoon systems, namely "pre-pond" and "in-pond" CEPT. While there is discussion of numerous CEPT plants, special attention is paid to the full-scale study and analysis of the CEPT upgrade at Riviera de Sao Lourenco, Brazil. This plant conducted full-scale tests of both "prepond" and "in-pond" CEPT. This thesis compares the advantages and disadvantages of "prepond" and "in-pond" CEPT, along with the effectiveness of each.by Mike R. Bourke, Jr.M.Eng

Bougainville Province: Text summaries, maps, code lists and village identification

The major purpose of the Papua New Guinea Agricultural Systems Project is to produce information on small holder (subsistence) agriculture at provincial and national levels (Allen et al 1995). Information was collected by field observation, interviews with villagers and reference to published and unpublished documents. Methods are described by Bourke et al. (1993). This Working Paper contains a written summary of the information on the Agricultural Systems in this Province, maps of the location of agriculture systems, a complete listing of all information in the database in coded form, and lists of villages with National Population Census codes, indexed by agricultural systems. This information is available as a map-linked database (GIS) suitable for use on a personal computer in ESRI and MapInfo formats. An Agricultural System is identified when a set of similar agricultural crops and practices occur within a defined area. Six criteria are used to distinguish one system from another: 1. Fallow type (the vegetation which is cleared from a garden site before cultivation). 2. Fallow period (the length of time a garden site is left unused between cultivations). 3. Cultivation intensity (the number of consecutive crops planted before fallow). 4. The staple, or most important, crops. 5. Garden and crop segregation (the extent to which crops are planted in separate gardens; in separate areas within a garden; or are planted sequentially). 6. Soil fertility maintenance techniques (other than natural regrowth fallows). Where one or more of these factors differs significantly and the differences can be mapped, then a separate system is distinguished. Where variation occurs, but is not able to be mapped at 1:500 000 scale because the areas in which the variation occurs are too small or are widely dispersed within the larger system, a subsystem is identified. Subsystems within an Agricultural System are allocated a separate record in the database, identified by the Agricultural System number and a subsystem number. Sago is a widespread staple food in lowland Papua New Guinea. Sago is produced from palms which are not grown in gardens. Most of the criteria above cannot be applied. In this case, systems are differentiated on the basis of the staple crops only. The Papua New Guinea Resource Information System (PNGRIS) is a GIS which contains information on the natural resources of PNG (Bellamy 1986). PNGRIS contains no information on agricultural practices, other than an assessment of land use intensity based on air photograph interpretation by Saunders (1993. The Agricultural Systems Project is designed to provide detailed information on agricultural practices and cropping patterns as part of an upgraded PNGRIS geographical information system. For this reason the Agricultural Systems database contains almost no information on the environmental settings of the systems, except for altitude and slope. The layout of the text descriptions, the database code files and the village lists are similar to PNGRIS formats (Cuddy 1987). The mapping of Agricultural Systems has been carried out on the same map base and scale as PNGRIS (Tactical Pilotage Charts, 1:500 000). Agricultural Systems were mapped within the areas of agricultural land use established by Saunders (1993) from aerial photography. Except where specifically noted, Agricultural Systems boundaries have been mapped without reference to PNGRIS Resource Mapping Unit (RMU) boundaries. Agricultural Systems are defined at the level of the Province (following PNGRIS) but their wider distribution is recognised in the database by cross-referencing systems which cross provincial borders. A preliminary view of the relationships between PNGRIS RMUs and the Agricultural Systems in this Province can be obtained from the listing of villages by Agricultural System, where RMU numbers are appended.

Autism McLean: Housing for Adults with ASD

In January 2020, six graduate students from the Stevenson Center at Illinois State University were assigned to conduct social research for Autism McLean, a local, volunteer organization that aims to promote the general welfare of children and adults with autism and to provide support for their families. The objective was to conduct an applied research project that met Autism McLean\u27s needs while providing an applied education to service minded students. The focus of the research was specifically on the housing assets and programs available in McLean County and whether those assets match the needs of people with autism

The Spitzer c2d Survey of Nearby Dense Cores. V. Discovery of a VeLLO in the "Starless" Dense Core L328

This paper reports the discovery of a Very Low Luminosity Object (VeLLO) in the "starless" dense core L328, using the Spitzer Space Telescope and ground based observations from near-infrared to millimeter wavelengths. The Spitzer 8 micron image indicates that L328 consists of three subcores of which the smallest one may harbor a source, L328-IRS while two other subcores remain starless. L328-IRS is a Class 0 protostar according to its bolometric temperature (44 K) and the high fraction ~72 % of its luminosity emitted at sub-millimeter wavelengths. Its inferred "internal luminosity" (0.04 - 0.06 Lsun) using a radiative transfer model under the most plausible assumption of its distance as 200 pc is much fainter than for a typical protostar, and even fainter than other VeLLOs studied previously. Note, however, that its inferred luminosity may be uncertain by a factor of 2-3 if we consider two extreme values of the distance of L328-IRS (125 or 310 pc). Low angular resolution observations of CO do not show any clear evidence of a molecular outflow activity. But broad line widths toward L328, and Spitzer and near-infrared images showing nebulosity possibly tracing an outflow cavity, strongly suggest the existence of outflow activity. Provided that an envelope of at most ~0.1 Msunis the only mass accretion reservoir for L328-IRS, and the star formation efficiency is close to the canonical value ~30%, L328-IRS has not yet accreted more than 0.05 Msun. At the assumed distance of 200 pc, L328-IRS is destined to be a brown dwarf.Comment: 29 pages, 8 figures, 1 table, to be published in Astrophysical Journa

Bringing back the Manchester Argus Coenonympha tullia ssp. davus (Fabricius, 1777): quantifying the habitat resource requirements to inform the successful reintroduction of a specialist peatland butterfly

The period 2021–2030 has been designated the UN decade of ecosystem restoration. A landscape-scale peatland restoration project is being undertaken on Chat Moss, Greater Manchester, UK, with conservation translocations an important component of this work. The Manchester Argus Coenonympha tullia ssp. davus, a specialist butterfly of lowland raised bogs in the northwest of England, UK is under threat due to severe habitat loss and degradation. A species reintroduction was planned for spring 2020. This study aimed to quantify the resource thresholds for C. tullia, in order to assess potential risks for the project. Thirteen peatland habitat patches with either recent historic or current C. tullia populations were surveyed for biotic and abiotic factors based on previous qualitative research on the species’ requirements. Percentage cover of two habitat resources was found to be the strongest predictor in models of C. tullia presence: cross-leaved heath Erica tetralix and hair's-tail cotton-sedge Eriophorum vaginatum. Critical inflection points on logistic regression curves were used to make quantitative estimates of the minimum requirement of each resource for population survival and the near-optimum abundance of each resource. The results of this study improve our understanding of C. tullia’s ecology and the restoration of peatlands for its reintroduction. Additionally, the method has wider utility for the quantitative assessment of habitat readiness before attempting species reintroductions
