Natural capital accounting perspectives: a pragmatic way forward

Introduction: Recent debates surrounding the application of natural capital accounting (NCA) have produced several approaches to further develop this system, as well as highlighted a number of conceptual and methodological issues that need to be resolved before mainstreaming NCA into policy and decision making. We argue that prolonged debate over the value concepts (i.e., exchange versus other values) underpinning different modifications to NCA has slowed progress in experimentation and uptake by policymakers.Outcomes: Consequently we propose three broad approaches which can be progressed in parallel to reinvigorate experimentation with the NCA principles and practice, while at the same time generating policy relevant tools and evidence bases for decision support. The three approaches are; extended SNA accounting anchored to the use of exchange values; a complementary accounts network (CAN) that utilizes plural values as supplementary accounts to the SNA system; and wealth accounting that focuses on measures of welfare and wellbeing. The three approaches are complementary and data developed in any one can inform the other two.Conclusions: We contend that CAN offers the most flexibility and opportunities to progress short term support for decision making on environmental issues which are now becoming urgent

Sustainable Agricultural Productivity Growth and Bridging the Gap for Small-Family Farms: Interagency Report to the Mexican G20 Presidency

In 2011, G20 leaders committed to sustainably increase agricultural (production and) productivity (paragraph 43 of the Cannes Declaration). They "agree(d) to further invest in agriculture, in particular in the poorest countries, and bearing in mind the importance of smallholders, through responsible public and private investment," they "decide(d) to invest in research and development of agricultural productivity. Early in 2012 Mexico, as G20 President, invited international organisations to examine practical actions that could be undertaken to sustainably improve agricultural productivity growth, in particular on small family farms. The preparation of this report, co-ordinated by the FAO and the OECD, responds to this request. It is a collaborative undertaking by Bioversity, CGIAR Consortium, FAO, IFAD, IFPRI, IICA, OECD, UNCTAD, Coordination team of UN High Level Task Force on the Food Security Crisis, WFP, World Bank, and WTO. We, the international organisations, are pleased to provide you with this joint report and look forward to continuing collaboration within the G20 framework to further elaborate and, as appropriate, implement the recommendations that it contains

Sex, gender, and health biotechnology: points to consider

<p>Abstract</p> <p>Background</p> <p>Reproductive technologies have been extensively debated in the literature. As well, feminist economists, environmentalists, and agriculturalists have generated substantial debate and literature on gender. However, the implications for women of health biotechnologies have received relatively less attention. Surprisingly, while gender based frameworks have been proposed in the context of public health policy, practice, health research, and epidemiological research, we could identify no systematic framework for gender analysis of health biotechnology in the developing world.</p> <p>Discussion</p> <p>We propose sex and gender considerations at five critical stages of health biotechnology research and development: priority setting; technology design; clinical trials; commercialization, and health services delivery.</p> <p>Summary</p> <p>Applying a systematic sex and gender framework to five key process stages of health biotechnology research and development could be a first step towards unlocking the opportunities of this promising science for women in the developing world.</p

The geography of yam cultivation in southern Nigeria:Exploring its social meanings and cultural functions

Background: Yam (Dioscorea spp.) is a very important common food crop in West Africa. Beyond its food and nutritious values, the ownership and cultivation of yam have many cultural, religious, and social meanings, which may vary between specific ethnic groups and regional areas. This study explored the diverse social, cultural, and religious perspectives associated with yam and its cultivation in southeastern Nigeria. Methods: We used a comparative approach and utilized in-depth, semistructured interviews, local narratives, and our experiential background to understand the similarities and differences in the local notions of yam and their impacts on the general societal structure across three ethnic regions in southeastern Nigeria. We discussed the findings on a thematic basis to reflect the social and cultural issues associated with the ownership and cultivation of yam. The themes ranged from religious practices, impact on social status, and gender relations. Results: We found no significant differences in the incidence of local perceptions and practices between the study areas. Conclusion: This study has demonstrated the importance and functions of yam crop in structuring the social, economic, religious and cultural fabric of the society

A screening tool to prioritize public health risk associated with accidental or deliberate release of chemicals into the atmosphere

The Chemical Events Working Group of the Global Health Security Initiative has developed a flexible screening tool for chemicals that present a risk when accidentally or deliberately released into the atmosphere. The tool is generic, semi-quantitative, independent of site, situation and scenario, encompasses all chemical hazards (toxicity, flammability and reactivity), and can be easily and quickly implemented by non-subject matter experts using freely available, authoritative information. Public health practitioners and planners can use the screening tool to assist them in directing their activities in each of the five stages of the disaster management cycle

Early changes in Orthopteran assemblages after grassland restoration : a comparison of space-for-time substitution versus repeated-measures monitoring

Grasslands harbour significant biodiversity and their restoration is a common intervention in biodiversity conservation. However, we know very little on how grassland restoration influences arthropod groups. Here we compared orthopteran assemblages in croplands, natural grasslands and one to four-year-old grasslands restored in a large-scale restoration on former croplands in Hortobágy National Park (E-Hungary). Sampling was done by standardized sweep-netting both in a repeated measures design and space-for-time substitution (chronosequence) design. General linear models with repeated measures from five years showed that species richness, abundance and Shannon diversity of orthopterans decreased in the year following restoration but increased afterwards. By the fourth year, species richness almost doubled and abundance increased almost ten-fold in restored grasslands compared to croplands. Multivariate analyses showed that species composition in the first two years did not progress much but by the third and fourth year there was partial overlap with natural grasslands. Local restoration conditions (last crop, seed mixture) and landscape configuration (proportion of natural grasslands < 1 km away) did not influence the above patterns in either the repeated measures or the chronosequence design, whereas time since restoration affected almost all community variables. Our results suggest that generalist ubiquitous species appeared in restored grasslands first and the more sensitive species colonized the restored fields gradually in later years. The qualitative and quantitative properties of the orthopteran assemblages in restored fields did not yet reach those of natural grasslands, therefore, our study suggests that the full regeneration of the orthopteran assemblages takes more than four years

Interspecies interactions and potential Influenza A virus risk in small swine farms in Peru

<p>Abstract</p> <p>Background</p> <p>The recent avian influenza epidemic in Asia and the H1N1 pandemic demonstrated that influenza A viruses pose a threat to global public health. The animal origins of the viruses confirmed the potential for interspecies transmission. Swine are hypothesized to be prime "mixing vessels" due to the dual receptivity of their trachea to human and avian strains. Additionally, avian and human influenza viruses have previously been isolated in swine. Therefore, understanding interspecies contact on smallholder swine farms and its potential role in the transmission of pathogens such as influenza virus is very important.</p> <p>Methods</p> <p>This qualitative study aimed to determine swine-associated interspecies contacts in two coastal areas of Peru. Direct observations were conducted at both small-scale confined and low-investment swine farms (n = 36) and in open areas where swine freely range during the day (n = 4). Interviews were also conducted with key stakeholders in swine farming.</p> <p>Results</p> <p>In both locations, the intermingling of swine and domestic birds was common. An unexpected contact with avian species was that swine were fed poultry mortality in 6/20 of the farms in Chancay. Human-swine contacts were common, with a higher frequency on the confined farms. Mixed farming of swine with chickens or ducks was observed in 36% of all farms. Human-avian interactions were less frequent overall. Use of adequate biosecurity and hygiene practices by farmers was suboptimal at both locations.</p> <p>Conclusions</p> <p>Close human-animal interaction, frequent interspecies contacts and suboptimal biosecurity and hygiene practices pose significant risks of interspecies influenza virus transmission. Farmers in small-scale swine production systems constitute a high-risk population and need to be recognized as key in preventing interspecies pathogen transfer. A two-pronged prevention approach, which offers educational activities for swine farmers about sound hygiene and biosecurity practices and guidelines and education for poultry farmers about alternative approaches for processing poultry mortality, is recommended. Virological and serological surveillance for influenza viruses will also be critical for these human and animal populations.</p
