Embedding co-management: community-based fisheries resource management regime in Lake Victoria, Tanzania

This paper discusses fisheries management reforms through involving local level institutions (LLFI). It is based on studies which were undertaken on TanzaniaÆs Lake Victoria fishery where LLFIs were established through the formation of Local enforcement Units, later named Beach Management Units (BMU), between 1998 and 2002. The paper takes the view that the overfishing problems that confront TanzaniaÆs fisheries management authorities are best understood from a social science perspective. The argument is that most communitiesÆ values and institutions are embedded in their societies. The same is however, not true for externally originated management tools and systems as is the case with BMUs. This paper shows that the BMUs established between 1998 and 2002, were not sufficiently grounded in their socio-cultural environment and this led them to be unsustainable and ineffective. The paper demonstrates that this mismatch by examining the different historical and social contexts in which livelihoods such as fishing emerged and was carried out. These social contexts generated social values that explain the individual behaviour of community members. It is such values that communities always strive to maintain in any activity including fishing. Thus, when confronted with situations that threaten these values, communities strategize or negotiate ways to cope. The coping strategies of two communities riparian to the lake are discussed. The paper therefore proposes a framework for making these units æfitÆ local conditions in order to make them effective and sustainable so as to reform fisheries management.Fishery management

Magnetic phase diagram of three-dimensional diluted Ising antiferromagnet Ni0.8_{0.8}Mg0.2_{0.2}(OH)2_{2}

$H$-$T$ diagram of 3D diluted Ising antiferromagnet Ni$_{c}$Mg$_{1-c}$(OH)$_{2}$ with $c$ = 0.8 has been determined from measurements of SQUID DC magnetization and AC magnetic susceptibility. At $H$ = 0, this compound undergoes two magnetic phase transitions: an antiferromagnetic (AF) transition at the N\'{e}el temperature $T_{N}$ (= 20.7 K) and a reentrant spin glass (RSG) transition at $T_{RSG}$ ($\approx$ 6 K). The $H$-$T$ diagram consists of the RSG, spin glass (SG), and AF phases. These phases meet a multicritical point $P_{m}$ ($H_{m}$ = 42 kOe, $T_{m}$ = 5.6 K). The irreversibility of susceptibility defined by $\delta$ (= $\chi_{FC} - \chi_{ZFC}$) shows a negative local minimum for 10 $\leq H \leq$ 35 kOe, suggesting the existence of possible glassy phase in the AF phase. A broad peak in $\delta$ and $\chi^{\prime \prime}$ at $H \geq$ 20 kOe for $T_{N}(c=0.8,H) \leq T \leq T_{N}(c=1,H=0)$ (= 26.4 K) suggests the existence of the Griffiths phase.Comment: 11 pages, 14 figures; J.

Country of Origin Labeling of Fresh Produce: A Consumer Preference Analysis

This paper investigates the relationships between country of origin labeling (COOL) issues and consumers concern about safety and health towards using of foreign produce. Results show that those who were married, self employed, had higher incomes, or possessed more education were more likely to support COOL. A consumer survey showed that about 84% of respondents overall, and more specifically, about 84% of female and 83% of male respondents would like markets to provide information about country of origin of fresh produce. The result also shows that about 73% of respondents regularly read food advertisements in newspapers and grocery brochures.Demand and Price Analysis, Food Consumption/Nutrition/Food Safety, International Relations/Trade,

Demographic Characteristics of Consumers who Read Grocery Brochures Regularly and Those who are willing to Switch Supermarkets to Buy Advertised Specials: An Analysis.

This study analyzed the influence of demographic and behavioral characteristics on the likelihood of a consumer to read food advertisements in grocery brochures and the likelihood of a consumer to shop at more than one store to purchase advertised specials. Overall, 73% and 46% of respondents read food advertisements and shop multiple stores to purchase advertised specials, respectively. Consumer characteristics which are shown to influence the reading of food advertisements and shopping at more than one food store to buy advertised specials were the possession of education beyond the 2/4 year college degree and the tendency to read ingredient labels.Consumer/Household Economics, Marketing,

Selecting Indicators for Assessing Neighbourhood Sustainability:The Metropolitan Lagos Workflow

Neighbourhood Sustainability Assessment Frameworks (NSAFs) are increasingly touted as crucial in planning and designing sustainable urban neighbourhoods. Ostensibly, NSAFs ensure that sustainability concerns are duly addressed following the recognition that neighbourhoods are key building blocks of urban areas. While the NSAF discourse has largely involved developed countries, the selection of appropriate indicators to use in an NSAF has remained a problem often because of little robust evidence to support the selected indicators. Also, as develoing countries are largely absent in this discourse, this paper presents an exemplar approach and workflow for selecting NSAF indicators for a Sub-Saharan Africa (SSA) context. Positivist techniques (weighted average, co-efficiency of variation, and content validity in ratio) are used to rank the significance of the stakeholders’ indicated perceptions and preferences collected using questionnaire surveys from metropolitan Lagos. This paper’s significance lies in showcasing the robust methodological approach and sound evidence-base for selecting the indicators based on input form diaparate stakeholders: including data requirements and workflow that SSA countries can easily adopt

Cobalt removal from wastewater using pine sawdust

Agricultural wastes can cause environmental problems if not well managed, but there is a lot of potential to use these wastes as raw material in other processes. In this investigation, pine sawdust was evaluated as an adsorbent in the treatment of wastewater containing cobalt ions. A two-level three-factor full-factorial experimental design with centre points was used to study the interactive effect of the operating parameters in order to achieve the best conditions for the batch adsorption of cobalt ions. A response surface analysis was also conducted to further understand the interactions amongst the factors such as adsorbent dose, solution pH and initial concentration. In addition, adsorption isotherms, namely the Freundlich and Langmuir, were used to characterize the removal of cobalt from the wastewater. It was observed that the combined effect of low adsorbent dose, high pH and high initial concentration of wastewater resulted in the highest adsorption capacity. The Freundlich isotherm provided a better fit to the experimental data than the Langmuir isotherm. Moreover, pine sawdust showed adsorption capabilities for cobalt, and hence it could be an option in the quest to use waste to treat wastewater

PUBLIC APPROVAL OF PLANT AND ANIMAL BIOTECHNOLOGY IN KOREA: AN ORDERED PROBIT ANALYSIS

This study analyzes predictors of Korean public acceptance of the use of biotechnology to create genetically modified food products. Results indicate that the consumers with above average knowledge of specific outcomes of genetic modification were more likely than those with inaccurate or no knowledge to approve use of plant or animal genetic modification for the creation of new food products. Young South Koreans consumers (ages 20 to 29 years old) were more likely than old consumers (ages 50 to 59) to approve use of biotechnology to create both plant and animal based foods. Further, those Koreans in favor of GM labeling were less likely to approve the use of biotechnology for the creation of food products. The results also suggest that public trust and confidence on various institutions associated with biotechnology is critical for the future of the technology. There was some evidence of differential biotechnology approval among consumers of different residential areas, income levels and political affiliation. Thus, those in cities, those with incomes above 40 million Won, and of liberal political affiliation were found to be more approving of animal biotechnology.Research and Development/Tech Change/Emerging Technologies,

Consumer Acceptance of Genetically Modified Foods in South Korea: Factor and Cluster Analysis

This study extends biotechnology discourse to cover South Korea in the Asian sub-continent showing a marked difference in perceptions between traditional and GM foods. Factor analysis suggests South Koreans may treat foods that are locally produced and those with no artificial flavors or colorings preferentially to GM foods. Additionally, South Koreans have concerns about perceived risks related to biotechnology, and, given a choice, they may pay more to avoid GM foods. Cluster analysis results yielded four consumer segments: (a) ardent supporters of the attribute of “naturalness†in foods, (b) those apprehensive about biotechnology, (c) the food adventurous, and (d) information seekers about biotechnology.consumer perceptions, factor and cluster analysis, food attributes, genetic modification, Consumer/Household Economics, Food Consumption/Nutrition/Food Safety,

CONSUMER ACCEPTANCE OF GENETICALLY MODIFIED FOODS IN KOREA: FACTOR AND CLUSTER ANALYSIS

The study applies multivariate statistical and econometric tools to estimate the importance of the various factors driving Korean consumer acceptance of GM food products. The evidence thus far on biotechnology is decidedly mixed: public perceptions of food biotechnology are characterized by ongoing tension between opposing forces. The South Korean perceptions about food in general and ranges from excitement about the promise of environmental and economic benefits from GM products to fear and distrust of the technology for unknown risks. This highlights the importance of credibility of private and public institutions responsible for certifying the safety of GM foods and implementing necessary regulatory controls on GM processes and products. In between, many people are undecided, trying to learn more about the issues and reach a definitive position. Encouraging though is that some people are eager to try new foods. Koreans strongly favors food naturalness, familiarity, and access just as the west countries. Results suggest that the South Korean Consumer priorities with respect to various biotechnology and general food issues are related to their socioeconomic and value attributes. This implies that, at least in the near term, there will be considerable divergence within the society in terms of acceptance of food biotechnology. The finding that large segments of the Korean society are either not fully informed or interested in learning more about biotechnology calls for a public education program. A program that may play a constructive role in not only informing consumers but help them in arriving at a socially optimal collective decisions on the wisdom and desirability of food biotechnology.Research and Development/Tech Change/Emerging Technologies,
