    And encouraging new evidence suggests that most of the world’s fisheries, including small-scale fisheries, which is usually not industrialized and that millions of people depend for food, can be maintained by community-based co.

    “Most of the world’s fisheries are not and never will be managed by strong central governments with hierarchical rules and means to enforce them,” said the Uruguayan Nicolas Gutierrez, PhD of Aquatic and Fishery Sciences at the University of Washington (USA ) and author of the paper published by Nature this week.

    “Our findings show that many fisheries around the world co-managed by communities are well managed under limited central government structures, provided that fishing communities be involved proactively. Community-based co-management is the only realistic solution for most of the world’s fisheries, and is an effective way to conserve water resources and livelihoods of communities dependent on them, “says the researcher.

    Mayors and fishing agreements

    With this management system the responsibility of the resources are shared between the government and users. On a smaller scale, this may mean that mayors and fishermen from different nations to agree to avoid fishing in each other’s waters.

    Examples of larger scale includes the most valuable fisheries of Chile, a mollusc called “crazy” and also known as abalone from Chile. It began growing in 1988 one local fishermen cooperative along a stretch of coast of 4 km, and which today extends an administration area 700 with 20,000 fishermen along 4,000 km of coastline.

    Although there are individual case studies co-managed fisheries, this new work uses data from 130 fisheries in 44 developed and developing, and includes items such as marine and freshwater, and various fishing gears and target species.

    The statistical analysis shows that co-management often fails unless it has key elements: the presence of prominent leaders in the community and social cohesion, ensuring clear incentives for fishermen, for example, the amount that can capture or area in which to fish, and protected areas, especially when combined with a regulated harvest within or outside the area and when the proposed protected area is controlled by local communities.

    “Our results show that additional resources should be allocated to efforts to identify community leaders and build social capital, not just to impose administrative tactics to exclude users,” said Gutierrez.

    The Nobel Ostrom was right

    The new study confirms the theories of Elinor Ostrom, who won the Nobel Prize in Economics in 2009 for defying the conventional wisdom that common property is always given as deficient and should be regulated by central authorities or privatized. According to Ostrom, resource users often develop sophisticated mechanisms for decision making and implementation of rules for handling conflicts of interest.

    “Elinor Ostrom was right,” says Omar Defeo, a professor at the University of Uruguay, scientific coordinator of the national fisheries administration and co-author Uruguay. “With community-based co-management, fishers are able to self-organize, maintain their resources and achieve sustainable fisheries.”

    After reading the article before posting, Ostrom said the work was “fabulous” and said: “It was very exciting to see the findings on the cohesion of the community based on norms, trust, communication, commitment and respect for leaders as the most important attributes that lead to a fisheries co-management success. ”

    For the study met Gutiérrez scientific information, government reports and non-governmental organizations, as well as personal interviews with 130 co-managed fisheries. The eight attributes evaluated, ranging from community empowerment towards sustainable catch up to increases in the abundance of fish and prices of what was caught.

    The best fishing

    With 40% of the fisheries with positive score at 6, 7 or 8 attributes, and another 25% scored positively in 4 or 5, the co-authors argue that community-based co-management “is a great promise for success and sustainability fisheries around the world. ”

    Ray Hilborn, Professor of Aquatic and Fishery Sciences at the University of Washington and coauthor of the study, participated in another Science article in 2009 in which it was noted that many major industrial fisheries and fisheries ecosystems are increasingly sustainable.

    “This new study illustrates the potential for growth in the world to manage sustainable fisheries and appropriate tools for industrial fisheries in countries with strong central governments are very different from those with small-scale fishing or without such strong central government” said the expert.

    Dr. Azucena Gracia of the Economics Unit of the Agri-Food and Natural Resources of the CITA has led a research project on the social acceptance of biodiesel by the citizens of Aragon. The research team consists of Dr. Luis Perez y Perez y Gabriela Zeballos of CITA and Dr. Jesús Barreiro Hurlé of Research and Training Institute for Agriculture and Fisheries (IFAP).

    The study was conducted based on the analysis of surveys of 400 residents of the city of Zaragoza in September last. The sample comprised 49 percent of women and 51 percent of men, all characterized on the basis of sociodemographic factors.

    CITA research reveals very little knowledge about biodiesel in the population. The majority of respondents have never used due to lack of information and then not sold in regular duty station.

    Individuals with greater knowledge about biodiesel have greater intention to use in general, even at a higher price. It is noteworthy that women are more willing to use biodiesel than men, and respondents with higher income and education.

    Respondents are more concerned that biodiesel can be produced from raw materials produced in Aragon, his production will decrease dependence on oil imports from the countries, “is less polluting than traditional diesel,” his use decrease emissions to the environment “and” production can help increase farmers’ incomes and rural areas “and to a lesser extent that” more expensive to produce than diesel from fossil fuels “and” you can lead to an increase in food prices, “indicating that Aragon citizens have positive attitudes towards biodiesel.

    Attitudes toward biodiesel impact on the intention to use and the aspects that influence are positively related to emissions, with the lowest energy dependence, the role he is called to play in rural and regional origin. That is, they intend to use more than those who think that is more environmentally friendly, reduces dependence on energy, promotes the development of rural and regional value origin.

    Biofuels, particularly biodiesel, have become an alternative in the short to medium term, to partially replace traditional fuels.

    Currently, both types of fuels coexist and compete in the market but with very different market shares. In Spain, biodiesel represents only 1% of consumption and the European Union (EU) has established that by the year 2020, the share of renewable energy (particularly biofuels) in transport sector to achieve at least 10%.

    To reach this result, researchers have been calculating the price with a model that measures the number of medals in terms of government spending on sports, among other variables. “This model allows us to measure precisely how much extra spending is needed to win a medal,” explained UC3M teachers, Juan de Dios Tena and J. Ramón Flores, who have done this study within the research group in Economics of Sport, led by Professor David Forrest, University of Salford (England) and also comprises Ismael Sanz, Universidad Rey Juan Carlos and Jaime Alvarez , University Complutense of Madrid.

    “We have estimated the relationship between these costs and Olympic success once also takes into account the effect of economic variables, political and relevant demographic, as the size of the country,” said Tena. This work was presented at the workshop “The Economic of the Olympic Games in Groningen in July 2008 under the title” Can governments buy Olympic medals? ” and is currently under review in a research journal.

    In the area of Economics of Sport these researchers use econometric models (usually regression type) to analyze sporting events in which conditions appear economic. The general idea of the hub is that there are many possible causes of a phenomenon. “A regression model provides an estimate of the individual effect of each of these cases once they control all the others,” says Professor Flores, allowing rigorous conclusions from statistical models that can determine the specific influence of a element in the sporting context.

    The dilemma to fire coach

    For football teams, for example, this group of researchers has analyzed the figure of technical trainer and found that the effect of firing a coach mid-season is more negative than positive when it tends to repeat this situation. “A coaching change reduces average number of points scored in eight games in a unit,” he commented.

    From the results obtained for several seasons by the league clubs in Argentina, the econometric model developed shows an inverse relationship between the redundancy and performance. In short, the more layoffs, the worse results in the medium term. “Similar work done in European leagues, where the number of layoffs is lower, show no such effect, suggesting that the abuse of layoffs may generate negative consequences in this context,” they conclude these professors in the Department of Statistics UC3M.

    Another related issue that these investigators have studied was the effect it had the Bosman ruling of 1995 in the competitiveness of major league soccer. Before it, in national competitions governed a very strong limitation on the number of foreigners per team fichables, resulting in the good foreign players landfall usually available at big clubs. With the new legislation removed that limitation, greatly increased the number of players available, which mid-level clubs could also be strengthened under properly and increase their level as well as the competitiveness of the tournaments.

    “To measure this increased use measures well known in the literature, for example the percentage of the total points achieved by the two, four or ten best teams in the league, while taking into account other factors that influenced the change of market, such as the introduction of the Champions League and their subsequent rewards “they say. The conclusion: since the entry into force of the Bosman ruling reduced the ratio of points of the two best teams in 2 per cent and eight at 4 percent.

    This type of data and research can provide guidance and assistance in the decision making process. In addition, the responses obtained can be extrapolated to broader contexts. “Our intention is to apply them profusely and assist in the resolution of questions that generate debate in society that produce interesting findings that are rarely studied with the rigor they deserve,” say these teachers on the campus of the UC3M Colmer, who have the impression that in this area are often presented as ‘analysis’ work goes beyond just mere opinion.

    “Because of the media for everything related to sports – complain – usually appear low statistical studies or made directly by amateurs, Derived from pedestrians from samples that do not offer the slightest guarantee.”

    “Our study proves that one of the main factors affecting progress of Spanish productivity is the high rate of temporary workers between industries with high technological intensity. These sectors are also those that provide the highest aggregate productivity growth (of all sectors) to our economy, “says Welcome Ortega, author of the study and researcher at the UMA.

    The labor law reform of 1984 introduced in our country the possibility of new temporary contracts. And after the subsequent reforms of 1994, 1997 and 2001, the use of temporary contracts has decreased only marginally since 1995 in some sectors.

    “We agree that this kind might have multiple beneficial effects such as providing companies the flexibility to adjust the templates to fluctuations in demand, companies provide workers to replace sick leave or maternity, or favoring entrepreneurs open new businesses by reducing fixed costs, “says the researcher.

    However, according to the study, the increase of temporary contracts has penalized the productivity growth in Spain and has generated greater instability in employment.

    The proportion of temporary, temporary result derived from wage employment and total – in 2004 reached 34.6% in Spain, even to 47.2% in regions such as Andalusia. For that year, the Organization for Economic Cooperation and Development (OECD) as a whole this ratio stood at 13%.

    “Spain is three times the rate of temporary employment of countries, from a cultural and labor market regulations are coming as France and Italy,” said Ortega.

    The use of temporary contracts is distorted

    “It is clear that employers use temporary contracts as a mechanism of adjustment of employment and, therefore, dominate this type of temporary contracts on the selection. Also, the temporary increase reduces the possibilities of investing in human capital or to receive specific training in the company, “says Ortega.

    The evidence from this research indicate that in the case of construction and services, increasing the proportion of temporary workers has not had a significant effect on productivity growth. However, the energy sector and advanced manufacturing is a “clear” decline in growth rate with respect to labor productivity.

    “The high seasonality may encourage further sectoral shifts in industries that traditionally prevails this time work, such as low productivity industries (agriculture, construction and catering), and divert investment into them. A further impediment to the development of high added value sectors, “they say.

    “We need an urgent reform of the labor market and sectoral policies that are effective for increasing permanent recruitment, at least in the companies belonging to these branches of production,” says the expert

    For companies engaged in R & D, the movement of researchers to competitors is an important challenge. Even if the company’s innovations are patented, the output of these employees can leak key information and knowledge to competitors. What researchers in an R & D are more likely to move to the competition? This research by Neus Palomeras and Eduardo Melero, Department of Business Economics of the UC3M attempts to answer this question.

    The most notable finding of the study, published in the journal Management Science, shows that, paradoxically, the inventors involved in the key areas of a company are the most “palatable” to competitors and those who are more likely to end up leaving to other companies innovative. Another noteworthy finding, the researchers claim, is that inventors working in larger teams are less “attractive” to competitors. “This means – Eduardo Melero said – that companies organize their innovation activities in working groups will be better able to retain their workers because it is more difficult to identify who provides the key knowledge in addition to that, obviously, be a whole team to another company is more complicated, “he explains.

    The results obtained in this study suggest that companies hire those inventors of competition which can absorb knowledge. Thus, by recognizing the characteristics of the researchers most likely to leave, managers can design policies for human resources and R & D to make the market less attractive to these workers, and therefore able to retain them, target these UC3M teachers.

    During the research the authors of the study took as a reference one of the leading companies in the field of technology to the nineties. They analyzed the movement to other firms that patented inventor at IBM and found those who were authors of innovations in higher quality, those with expertise in key business areas, in addition, other companies do not dominate were more likely to leave the company. “Keep in mind that companies’ human factor is important in transferring knowledge between them,” said Neus Palomeras, he decided to start this research to confirm this fact in a previous study of the licensing market.

    The figure of the inventor has always been important to obtain innovations clearly. “What is true – added Professor Melero – is that as knowledge has become more complex and increased professional specialization of research and development companies, the figure of an inventor who has a broad vision, and complete global innovations that are involved gains value. “

    “We’ve reached the end of a century of policies that tend to favor the export of raw materials and food in Africa. The continent is beginning to turn its gaze to agricultural innovation as a new engine of regional trade and prosperity,” said Calestous Juma, director of the study and researcher at the Belfer Center at Harvard University.

    The study’s strategy calls on governments to make African agricultural expansion in the spotlight in all decisions. Since the transport infrastructure and communication, to education beyond secondary education and investment in R & D.

    “Africa still has vast arable land and abundant labor, which, in agreeing a common approach and establish sound policies, could lead to increased production, income and food security, experts say.

    Key elements in making this transition

    Some of the steps to achieve change in Africa go through the use of latest technologies (including modern biotechnology) and investment in geographic sciences to enable optimal management of natural resources.

    The experts also considered necessary the constant expansion of basic infrastructure (telecommunications, transport, energy and irrigation), enhancement of technical training, especially for women and the practical knowledge and the creation of new companies especially in seed production, agricultural mechanization, food storage and processing.

    “The agricultural revolution in Africa is an achievable goal, provided that the continent known to focus on developing small-scale agriculture that can respond to national and regional food needs,” says Juma.

    Food production in Africa is low because it is reversed

    According to survey data, global agriculture in the last 40 years has been characterized by an increase in food production per capita of 17%. Similarly, African agriculture has gone to the opposite direction. It has grown coffee, cocoa and other export items, but food production has fallen 10% since 1960 due to low investments in the sector.

    Throughout these four decades, have stalled production levels and farm incomes, as well as poverty rates, these figures become worse in some cases.

    Although 70% of Africans belong to the world agricultural production is so low that nearly 250 million people (one quarter of the world population) are malnourished. One third of sub-Saharan Africa suffer from chronic hunger, while drought, land degradation and disease and appear to be endemic.

    Juma highlights the importance of being able to look beyond the problems and take advantage of the vast tracts of Africa, water resources and energy. “It is the only continent with arable land and available for expanding agriculture. Southern Sudan alone could feed the whole of Africa if developed properly, “he says.

    A study of the political dimension

    The work has gained a political dimension because of its presentation by the President of Tanzania, Jakaya Kikwete, the meeting of the leaders of the East African Community (EAC), which takes place today in Arusha, Tanzania. Moreover, the 19-member Common Market for Eastern and Southern Africa – COMESA, the continent’s largest trading bloc, have already implemented the preliminary results of the study.

    “The plan would combine the use of the latest science and technology, infrastructure expansion, enhancement of technical training and stimulation of business development. If you focus on women and rural prosperity, Africa would create a more agricultural revolution integral, “says Juma.

    “This remarkable statement, in absolute contrast with the deeply rooted and gloomy picture we have of the continent, it serves to present a series of investigations that are published today and offer clear solutions to transform the sub-Saharan agriculture and hence their economy, “says the researcher.
