Ecosystem services and adaptation for agriculture and food security: analysis of two decades (1991–2011) of financing by the Global Environment Facility

Investing in global environmental and adaptation benefits in the context of agriculture and food security initiatives can play an important role in promoting sustainable intensification. This is a priority for the Global Environment Facility (GEF), created in 1992 with a mandate to serve as financial mechanism of several multilateral environmental agreements. To demonstrate the nature and extent of GEF financing, we conducted an assessment of the entire portfolio over a period of two decades (1991–2011) to identify projects with direct links to agriculture and food security. A cohort of 192 projects and programs were identified and used as a basis for analyzing trends in GEF financing. The projects and programs together accounted for a total GEF financing of US$1,086.8 million, and attracted an additional US$6,343.5 million from other sources. The value-added of GEF financing for ecosystem services and resilience in production systems was demonstrated through a diversity of interventions in the projects and programs that utilized US$810.6 million of the total financing. The interventions fall into the following four main categories in accordance with priorities of the GEF: sustainable land management (US$179.3 million), management of agrobiodiversity (US$113.4 million), sustainable fisheries and water resource management (US$379.8 million), and climate change adaptation (US$138.1 million). By aligning GEF priorities with global aspirations for sustainable intensification of production systems, the study shows that it is possible to help developing countries tackle food insecurity while generating global environmental benefits for a healthy and resilient planet.

A model-based assessment of the effects of projected climate change on the water resources of Jordan

This paper is concerned with the quantification of the likely effect of anthropogenic climate change on the water resources of Jordan by the end of the twenty-first century. Specifically, a suite of hydrological models are used in conjunction with modelled outcomes from a regional climate model, HadRM3, and a weather generator to determine how future flows in the upper River Jordan and in the Wadi Faynan may change. The results indicate that groundwater will play an important role in the water security of the country as irrigation demands increase. Given future projections of reduced winter rainfall and increased near-surface air temperatures, the already low groundwater recharge will decrease further. Interestingly, the modelled discharge at the Wadi Faynan indicates that extreme flood flows will increase in magnitude, despite a decrease in the mean annual rainfall. Simulations projected no increase in flood magnitude in the upper River Jordan. Discussion focuses on the utility of the modelling framework, the problems of making quantitative forecasts and the implications of reduced water availability in Jordan.

An integrated assessment of carbon dioxide capture and storage in the UK

Geological carbon dioxide storage (CCS) has the potential to make a significant contribution to the decarbonisation of the UK. Amid concerns over maintaining security, and hence diversity, of supply, CCS could allow the continued use of coal, oil and gas whilst avoiding the CO2 emissions currently associated with fossil fuel use. This project has explored some of the geological, environmental, technical, economic and social implications of this technology. The UK is well placed to exploit CCS with a large offshore storage capacity, both in disused oil and gas fields and saline aquifers. This capacity should be sufficient to store CO2 from the power sector (at current levels) for a least one century, using well understood and therefore likely to be lower-risk, depleted hydrocarbon fields and contained parts of aquifers. It is very difficult to produce reliable estimates of the (potentially much larger) storage capacity of the less well understood geological reservoirs such as non-confined parts of aquifers. With the majority of its large coal fired power stations due to be retired during the next 15 to 20 years, the UK is at a natural decision point with respect to the future of power generation from coal; the existence of both national reserves and the infrastructure for receiving imported coal makes clean coal technology a realistic option. The notion of CCS as a ‘bridging’ or ‘stop-gap’ technology (i.e. whilst we develop ‘genuinely’ sustainable renewable energy technologies) needs to be examined somewhat critically, especially given the scale of global coal reserves. If CCS plant is built, then it is likely that technological innovation will bring down the costs of CO2 capture, such that it could become increasingly attractive. As with any capitalintensive option, there is a danger of becoming ‘locked-in’ to a CCS system. The costs of CCS in our model for UK power stations in the East Midlands and Yorkshire to reservoirs in the North Sea are between £25 and £60 per tonne of CO2 captured, transported and stored. This is between about 2 and 4 times the current traded price of a tonne of CO2 in the EU Emissions Trading Scheme. In addition to the technical and economic requirements of the CCS technology, it should also be socially and environmentally acceptable. Our research has shown that, given an acceptance of the severity and urgency of addressing climate change, CCS is viewed favourably by members of the public, provided it is adopted within a portfolio of other measures. The most commonly voiced concern from the public is that of leakage and this remains perhaps the greatest uncertainty with CCS. It is not possible to make general statements concerning storage security; assessments must be site specific. The impacts of any potential leakage are also somewhat uncertain but should be balanced against the deleterious effects of increased acidification in the oceans due to uptake of elevated atmospheric CO2 that have already been observed. Provided adequate long term monitoring can be ensured, any leakage of CO2 from a storage site is likely to have minimal localised impacts as long as leaks are rapidly repaired. A regulatory framework for CCS will need to include risk assessment of potential environmental and health and safety impacts, accounting and monitoring and liability for the long term. In summary, although there remain uncertainties to be resolved through research and demonstration projects, our assessment demonstrates that CCS holds great potential for significant cuts in CO2 emissions as we develop long term alternatives to fossil fuel use. CCS can contribute to reducing emissions of CO2 into the atmosphere in the near term (i.e. peak-shaving the future atmospheric concentration of CO2), with the potential to continue to deliver significant CO2 reductions over the long term.

Regional climate change mitigation with crops: context and assessment

The intention of this review is to place crop albedo biogeoengineering in the wider picture of climate manipulation. Crop biogeoengineering is considered within the context of the long-term modification of the land surface for agriculture over several thousand years. Biogeoengineering is also critiqued in relation to other geoengineering schemes in terms of mitigation power and adherence to social principles for geoengineering. Although its impact is small and regional, crop biogeoengineering could be a useful and inexpensive component of an ensemble of geoengineering schemes to provide temperature mitigation. The method should not detrimentally affect food security and there may even be positive impacts on crop productivity, although more laboratory and field research is required in this area to understand the underlying mechanisms.

The "value" of property rights in social security law

This article provides a critical examination of the way that property rules are applied judicially in the context of social security law concerned with the assessment of capital, and especially in connection with the determination of ownership and the valuation of assets, which can have a critical bearing on entitlement to various means-tested benefits.

Multimodel assessment of water scarcity under climate change

Water scarcity severely impairs food security and economic prosperity in many countries today. Expected future population changes will, in many countries as well as globally, increase the pressure on available water resources. On the supply side, renewable water resources will be affected by projected changes in precipitation patterns, temperature, and other climate variables. Here we use a large ensemble of global hydrological models (GHMs) forced by five global climate models and the latest greenhouse-gas concentration scenarios (Representative Concentration Pathways) to synthesize the current knowledge about climate change impacts on water resources. We show that climate change is likely to exacerbate regional and global water scarcity considerably. In particular, the ensemble average projects that a global warming of 2 degrees C above present (approximately 2.7 degrees C above preindustrial) will confront an additional approximate 15% of the global population with a severe decrease in water resources and will increase the number of people living under absolute water scarcity (< 500 m(3) per capita per year) by another 40% (according to some models, more than 100%) compared with the effect of population growth alone. For some indicators of moderate impacts, the steepest increase is seen between the present day and 2 degrees C, whereas indicators of very severe impacts increase unabated beyond 2 degrees C. At the same time, the study highlights large uncertainties associated with these estimates, with both global climate models and GHMs contributing to the spread. GHM uncertainty is particularly dominant in many regions affected by declining water resources, suggesting a high potential for improved water resource projections through hydrological model development.

Metabolomic assessment with CE-MS of the nutraceutical effect of Cystoseira spp extracts in an animal model

There is a need of scientific evidence of claimed nutraceutical effects, but also there is a social movement towards the use of natural products and among them algae are seen as rich resources. Within this scenario, the development of methodology for rapid and reliable assessment of markers of efficiency and security of these extracts is necessary. The rat treated with streptozotocin has been proposed as the most appropriate model of systemic oxidative stress for studying antioxidant therapies. Cystoseira is a brown alga containing fucoxanthin and other carothenes whose pressure-assisted extracts were assayed to discover a possible beneficial effect on complications related to diabetes evolution in an acute but short-term model. Urine was selected as the sample and CE-TOF-MS as the analytical technique to obtain the fingerprints in a non-target metabolomic approach. Multivariate data analysis revealed a good clustering of the groups and permitted the putative assignment of compounds statistically significant in the classification. Interestingly a group of compounds associated to lysine glycation and cleavage from proteins was found to be increased in diabetic animals receiving vehicle as compared to control animals receiving vehicle (N6, N6, N6-trimethyl-L-lysine, N-methylnicotinamide, galactosylhydroxylysine, L-carnitine, N6-acetyl-N6-hydroxylysine, fructose-lysine, pipecolic acid, urocanic acid, amino-isobutanoate, formylisoglutamine. Fructoselysine significantly decreased after the treatment changing from a 24% increase to a 19% decrease. CE-MS fingerprinting of urine has provided a group of compounds different to those detected with other techniques and therefore proves the necessity of a cross-platform analysis to obtain a broad view of biological samples.

A virtual clinic : telemetric assessment and monitoring for rural and remote areas

This article reports the establishment of a pilot ‘virtual clinic’ in a rural region of Victoria, Australia. Using low-cost videophones that work across ordinary phone lines, together with off-the-shelf (mostly automatic) clinical tools, local volunteers have been trained to mediate a virtual consultation between simulated patients and local GPs. This system has the potential to save long trips into town by such patients since the traditional ‘home visit’ is not feasible, as well as to provide regular home monitoring for those with chronic conditions. This in turn should impact favourably on ambulance deployment, sometimes enabling patients to avoid going to hospital or allowing them to come home sooner than otherwise would be the case, and generally to offer a sense of medical security to those living in isolated regions.

Committing to quality learning through adaptive online assessment

With advances in computer-based technologies and the emergence of e-learning, there are unprecedented opportunities to reconsider assessment of learning (and, axiomatically, of teaching) and how this can be undertaken. One approach is adaptive assessment. Although it has existed in the tertiary environment since the time of the oral examination, advanced technologies allow much fuller exploitation of the possibilities inherent in a dynamic system of testing that responds to the user. Having described the characteristics of adaptive assessment, this paper considers how it can achieve significant pedagogical aims within the sector. The paper differentiates between adaptive assessment to assist learning and adaptive assessment to assess achievement. How adaptive assessment can be put in place and salient issues, such as security and system integrity, when such assessment is used for credit, are then discussed. The paper concludes that the capability exists but it has yet to be exploited within higher education as a viable approach to assessment and as a contributor to quality learning.

A retail supply chain risk assessment conceptual model

Supply chains are increasingly relying on information and communications technologies and in particular electronic commerce to facilitate transactions between supply chain partners. The adoption of these enabling technologies brings several enhancements to the conduct of business including gains in efficiency. However there are also drawbacks inherent in these technologies that include threats that are imposed on businesses that use them. This paper presents a study on retail supply chains and the risks and vulnerabilities that cooperating supply chain partners are exposed to when adopting these technologies. In particular, the paper discusses the various threats and vulnerabilities of retail supply and presents a conceptual model of such risks.

E-business security management for Australian small SMEs - a case study

Small and Medium sized Enterprises (SMEs) play an important role within the Australian economy. There is a strong business case for Australian SMEs to be involved in e-business, which has been realised as the use of the Internet for performing business activities continues to increase. The evidence available indicates the uptake and advancement of performing e-business activities shall be dependent on the ability of Australian SMEs to secure their e-business systems. This paper presents the results of a case study, which applied a previously developed methodology to a small SME e-business system. The purpose was to validate the ability of the Australian Small to Medium Enterprise E-business Security Methodology (ASME-EBSM) to provide an effective security management strategy for Australian SMEs. The outcome demonstrated that this approach was both feasible and realistic for providing recommendations to secure the e-business activities performed and to protect the small SME e-business system.

Political Islam and human security

Summary: "In the wake of the September 11 and subsequent terrorist attacks, the academic and media commentaries on Islam the religion and Islam the basis for political ideology haves received an unprecedented high level of exposure and attention. The acts of political violence by extremist groups and the omnipresent war on terror have added fresh uncertainties to an already complex global order. Just as terrorism and counter-terrorism are locked in a mutually re-enforcing symbiosis, the sense of insecurity felt by Muslims and non-Muslims alike is mutually dependent and has the potential to escalate. This general assessment holds true for Muslims living in the Muslim world and beyond. The pervasive sense of being under attack physically and culturally by the United States and its allies has contributed to a growing unease among Muslims and re-enforced deep-seated mistrust of the ʻWestʼ. Public articulation of such misgivings has in turn, lent credence to Western observers who posit an inherent antipathy between the West and the Muslim world. The subsequent policies that have emerged in this context of fear and mutual distrust have contributed to the vicious cycle of insecurity. The present volume is anchored in the current debates on the uneasy and potentially mutually destructive relationship between the Muslim world and certain West countries. It brings together leading international scholars in this interdisciplinary field to deal with such inter-related questions as the nature of Islamism, the impact of the ʻwar on terrorʼ on the spread of militancy, the growing sense of being under siege by Muslim Diasporas and the many unintended ramifications of a security-minded world order. This volume deliberately focuses on these issues both at a broad theoretical level but more importantly in the form of a number of prominent case studies including Indonesia, Algeria and Turkey."--Publisher description.

User participation in the performance assessment of school buildings : a study of six primary schools in the Bellarine Peninsula region

Young children spend a significant portion of their lives at primary school. This research traces the development of school facilities in Victoria and examines the performance of six primary schools from the users' perspective. Performance assessments were carried out using participatory evaluation methods that included Touring Interviews with small groups of students aged from six to twelve years. The study found that participatory evaluation methods with both student and staff users generate significant information to improve school facilities. User comments were analysed with respect to 14 aspects of building quality and serviceability including character, thermal environment, privacy and flexibility. The study concludes that school buildings do not meet a number of key user requirements. Children expressed dissatisfaction with furniture and equipment in their classrooms and the playground, and to a lesser extent with student toilets, security of their school bags and personal privacy. Staff were dissatisfied with the provision of withdrawal areas and specialist spaces. Department of School Education facilities guidelines do not address the concerns of school users or meet user needs.

The relationship among malingering, psychopathy, and the MMPI-2 validity scales in maximum security forensic psychiatric inpatients

The records of 392 men hospitalized in a maximum security forensic psychiatric hospital were reviewed. Demographic information was collected as well as data from the men's performance on the Psychopathy Checklist-Revised (PCL-R) and Minnesota Multiphasic Personality Inventory-2 (MMPI-2). Prevalence rates for malingering were low across the sample. However, results of chi-square analysis revealed that those who scored high on the PCL-R received a diagnosis of malingering significantly more frequently than those who scored low on the PCL-R. Clinical applications and theoretical implications of the results are discussed.

Towards a knowledge perspective in information security risk assessments - an illustrative case study

Many methodologies exist to assess the security risks associated with unauthorized leakage, modification and interruption of information for a given organisation. We argue that the traditional orientation of these methodologies, towards the identification and assessment of technical information assets, obscures key risks associated with the cultivation and deployment of organisational knowledge. Our argument is developed through an illustrative case study in which a well-documented methodology is applied to a complex data back-up process. This process is seen to depend, in subtle and often informal ways, on knowledge to sustain operational complexity, handle exceptions and make frequent interventions. Although typical information security methodologies identify people as critical assets, we suggest a new approach might draw on more detailed accounts of individual knowledge, collective knowledge, and their relationship to organisational processes. Drawing on the knowledge management literature, we suggest mechanisms to incorporate these knowledge-based considerations into the scope of information security risk methodologies.
