The Dilemmas of Risk-Sensitive Development on a Small Volcanic Island

Abstract

In the Small Islands Developing State (SIDS) of St Vincent and the Grenadines in the Caribbean, the most destructive disasters in terms of human casualties have been the multiple eruptions of La Soufrière volcano situated in the north of St Vincent. Despite this major threat, people continue to live close to the volcano and national development plans do not include risk reduction measures for volcanic hazards. This paper examines the development options in volcanic SIDS and presents a number of conundrums for disaster risk management on the island of St Vincent. Improvements in monitoring of volcanic hazards and ongoing programmes to enhance communications systems and encourage community preparedness planning have increased awareness of the risks associated with volcanic hazards, yet this has not translated into more risk-informed development planning decisions. The current physical development plan in fact promotes investment in infrastructure in settlements located within the zone designated very high-hazard. However, this is not an anomaly or an irrational decision: severe space constraints in SIDS, as well as other historical social and economic factors, limit growth and options for low-risk development. Greater attention needs to be placed on developing measures to reduce risk, particularly from low-intensity hazards like ash, limiting where possible exposure to volcanic hazards and building the resilience of communities living in high-risk areas. This requires planning for both short- and longer-term impacts from renewed activity. Volcanic SIDS face multiple hazards because of their geography and topography, so development plans should identify these interconnected risks and options for their reduction, alongside measures aimed at improving personal preparedness plans so communities can learn to live with risk.

Ensuring Resilience of Natural Resources under Exposure to Extreme Climate Events

by Brent Jacobs, Louise Boronyak-Vasco, Kristy Moyle and Peat Leith

Abstract

Natural resources directly support rural livelihoods and underpin much of the wealth of rural and regional Australia. Climate change manifesting as increasing frequency and or severity of extreme weather events poses a threat to sustainable management of natural resources because the recurrence of events may exceed the resilience of natural systems or the coping capacity of social systems. We report the findings of a series of participatory workshops with communities in eight discrete landscapes in South East New South Wales, Australia. The workshops focused on how natural resource management (NRM) is considered in the Prevent-Prepare-Respond-Recover emergency management cycle. We found that NRM is generally considered only in relation to the protection of life and property and not for the intrinsic value of ecosystem services that support communities. We make three recommendations to improve NRM under extreme climate events. Firstly, the support to communities offered by emergency management agencies could be bolstered by guidance material co-produced with government NR agencies. Secondly, financial assistance from government should specifically target the restoration and maintenance of green infrastructure to avoid loss of social-ecological resilience. Thirdly, action by natural resource dependent communities should be encouraged and supported to better protect ecosystem services in preparation for future extreme events. Full article

Critical Minerals and Energy–Impacts and Limitations of Moving to Unconventional Resources

by Benjamin C. McLellan, Eiji Yamasue, Tetsuo Tezuka, Glen Corder, Artem Golev and Damien Giurco

Abstract

The nexus of minerals and energy becomes ever more important as the economic growth and development of countries in the global South accelerates and the needs of new energy technologies expand, while at the same time various important minerals are declining in grade and available reserves from conventional mining. Unconventional resources in the form of deep ocean deposits and urban ores are being widely examined, although exploitation is still limited. This paper examines some of the implications of the transition towards cleaner energy futures in parallel with the shifts through conventional ore decline and the uptake of unconventional mineral resources. Three energy scenarios, each with three levels of uptake of renewable energy, are assessed for the potential of critical minerals to restrict growth under 12 alternative mineral supply patterns. Under steady material intensities per unit of capacity, the study indicates that selenium, indium and tellurium could be barriers in the expansion of thin-film photovoltaics, while neodymium and dysprosium may delay the propagation of wind power. For fuel cells, no restrictions are observed. Full article

Forest Health Management and Detection of Invasive Forest Insects

by Kaelyn Finley and Sophan Chhin

Resources 2016, 5(2), 18; https://doi.org/10.3390/resources5020018 - 7 May 2016

Cited by 11 | Viewed by 6825

Abstract

The objectives of this review paper are to provide an overview of issues related to forest health and forest entomology, explain existing methods for forest insect pest detection, and provide background information on a case study of emerald ash borer. Early detection of potentially invasive insect species is a key aspect of preventing these species from causing damage. Invasion management efforts are typically more feasible and efficient if they are applied as early as possible. Two proposed approaches for detection are highlighted and include dendroentomology and near infrared spectroscopy (NIR). Dendroentomology utilizes tree ring principles to identify the years of outbreak and the dynamics of past insect herbivory on trees. NIR has been successfully used for assessing various forest health concerns (primarily hyperspectral imaging) and decay in trees. Emerald ash borer (EAB) (Agrilus planipennis), is a non-native beetle responsible for widespread mortality of several North American ash species (Fraxinus sp.). Current non-destructive methods for early detection of EAB in specific trees are limited, which restricts the effectiveness of management efforts. Ongoing research efforts are focused on developing methods for early detection of emerald ash borer. Full article

Paddy Farmers’ Sustainability Practices in Granary Areas in Malaysia

Abstract

Food safety is a serious concern among the consumers of agricultural products. Toxicity risks are created by the acute presence of contaminating chemicals in foods. The usage of chemical inputs in paddy farms has not only caused health issues for farmers but it has also adversely affected the environment, killed animals, and polluted air and water. This creates controversial issues that need immediate attention, since sustainable agriculture needs to meet both consumers’ and farmers’ welfare in terms of food and farmers’ safety, respectively. This study looks at paddy farming practices and the creation of the Farmer Sustainability Index as a measurement to gauge whether farmers are practicing sustainable agriculture by following the Rice Check guideline that has been stipulated by the Department of Agriculture, Malaysia. The questionnaire was constructed to capture the 16 farming practices based on the Rice Check guideline and a score was given to each practice to see whether the guideline is being followed. The data from the questionnaire were analyzed and the Farmer Sustainability Index was calculated. The range of index is from 0 to 100, where 0 is not sustainable at all and 100 is highly sustainable. Eighty (80) paddy farmers from Sungai Petani, Kedah participated in the study and the result shows that 80% of the farmers practice quite unsustainable paddy farming with an average score of less than 40.0 on a scale of 0–100.
