The escalation in world food prices and its implications for the Caribbean

During the last years, the steep increase in food prices has been one of the most distinctive characteristics of the world economy. Many factors have been hypothesized as the main drivers of this phenomenon, both structural and temporary. International food inflation has had perceptible effects on food importing countries and regions. As such, the Caribbean has suffered the impact mainly through four channels, namely, domestic inflation, imports bill and trade balance, poverty and indigence rates, and equity. This study addresses empirically these issues from a regional perspective.

Paraguay: a housing finance proposal for middle- to low-income groups

The construction and ownership of homes is fundamental to economic development, the generation of wealth and the formation of the middle class. Although a number of studies have been conducted and programmes implemented in recent decades, there remains a significant housing deficit in Paraguay and Latin America, indicating that such programmes have been unsuccessful. For families unable to document a steady income, the main obstacle to homeownership is often financing. This paper aims to demonstrate the economic and financial feasibility —provided there is sufficient political will and coordination between public and private entities— of a project to build 75,000 homes for 300,000 people (4.5% of the Paraguayan population) with middle to low incomes. The median household income in this segment, for which there is a significant shortage of decent housing, is US$ 396.50. A maximum of US$ 63.44 per month may be set aside for housing costs.

Vila da Barca, das palafitas ao conjunto habitacional: análise sobre a (im)permanência dos moradores na área

Este trabalho apresenta uma reflexão sobre a atual orientação da política habitacional brasileira de intervir em áreas de assentamentos precários, sem a remoção dos moradores, de modo a garantir sua permanência nos locais infraestruturados. O eixo da investigação gira em torno da seguinte questão: em que medida a atual orientação da política habitacional brasileira de intervir em áreas de assentamentos precários, sem a remoção da população, garante efetivamente a permanência dos moradores nos referidos locais, particularmente no Projeto de Urbanização e Habitação da Vila da Barca. O estudo apóia-se em referenciais teóricos sobre a produção da cidade capitalista e a desigualdade de apropriação do solo urbano, processos estes que impactam diretamente na constituição dos assentamentos precários como espaço de moradia para as frações da classe trabalhadora brasileira, que não conseguem acessar o mercado privado da habitação, dado os mecanismos de formação de preços da terra urbanizada. A pesquisa foi desenvolvida com base no método dialético, tendo como procedimento metodológico o levantamento bibliográfico, documental e de campo, sendo entrevistados 35 moradores que foram remanejados pelo projeto urbanístico da Vila da Barca. Os resultados apontam que as formas precárias de moradia popular constituídas em áreas insalubres e inadequadas, como os cortiços, as favelas, e, no caso de Belém, as baixadas, historicamente, foram removidas de forma repressiva pelo poder público. Entende-se que os projetos urbanísticos padronizados desenvolvidos na atualidade e voltados para o atendimento da necessidade de moradia dos trabalhadores, ainda que apresentem em sua configuração o tema da permanência, preservam os interesses da produção da cidade capitalista e evidenciam a lógica de segregação sócio-espacial, pois não imprimem mudanças substantivas na realidade das famílias. Além disso, ao contrário do que é propagado pelo discurso estatal, a pesquisa realizada na Vila da Barca, demonstra que tais projetos não conseguem garantir a fixação dos moradores nos locais de intervenção, uma vez que desarticulam as estratégias de sobrevivência das famílias, que sem condições financeiras e impossibilitadas de arcarem com os custos da nova moradia (taxas de serviços urbanos), tendem a vender os imóveis que lhes foram destinados, reproduzindo em outros assentamentos precários as condições anteriores de vida. Desta forma, o Projeto da Vila da Barca, concebido para resolver a situação de moradia das famílias da área, gerou graves consequências para as mesmas, em especial, a desestruturação das atividades ocupacionais, demonstrando os limites da intervenção estatal de acordo com a lógica de produção da cidade capitalista.

Estudo da distribuição espacial dos condomínios horizontais fechados e loteamentos fechados na cidade de Rio Claro-SP

In Brazil, the proliferation phenomenon of gated communities and land lots had its origins in big cities, such as Rio de Janeiro and Sao Paulo, since 1970. The implementation of these types of intramural housing are done in expanding are as of the city, based on the availability of bigger lots, lower land prices, and the search for are as closer to nature. The gated communities and land lots that, initially, had their architecture only accessible to the higher social classes, as a second home alternative away from urban problems, nowadays they can be reached by other social classes as well. Gated communities and land lots find their way to the center of larger cities, sustained mostly by the speech of real state entrepreneurs, and by its social “status”, a new emerging characteristic of this time period. The expansion of gated communities and land lots also change the cities lands cape and social spatial configuration. This work, therefore, attends the localization of gated communities and land lots spread out in the city of Rio Claro. It analyzes the scale in which the dynamics of the city’s urban expansion influenced the current distribution of these types of housing

Trade Liberalization, Corn Prices and a Rural Community in Guatemala

Trade liberalization policies in Guatemala have impacted agricultural production. This thesis focuses on how trade liberalization has happened, what have been the impacts at a national level and describes how a community has adapted to the implementation of these policies. The implementation of trade was influenced by several, international and national institutions. Among the international institutions are the World Bank, the World Trade Organization and the United States Agency for International Development. At the national level the institutions that have partaken in shaping the trade policies are the military and the owners of capital and labor. The implementation of trade policies at a national level has affected national corn prices, population level diets and to some extent reduced poverty levels. At a local level trade liberalization policies have impacted land holdings, increased intensification of agriculture, including agrochemical, machinery and crop plantations per year, and consumption rates of corn have been affected. Maximization of the benefits and minimization of the detrimental effects can happen with the implementation of policies that promote food security, improve access to health and education, and prevent environmental and human health consequences from the intensification of agriculture and at the same time continue with the production of non-traditional agricultural products.

Co-Product Prices May Be Nearing Seasonal Low

The supply of corn milling co-products from ethanol production has increased rapidly over the last several years. Based on United States Department of Agriculture (USDA) projections of corn ground for ethanol production, approximately 38 million tons of distillers grains would have been produced in the 2009-10 marketing year, with 40 million tons projected for the 2010-11 marketing year. While supply has grown, so too has demand from both domestic and international users. Cattle feeders in particular have found wet distillers grains plus solubles (WDGS), modified wet distillers grains plus solubles (MWDGS) and dried distillers grains plus solubles (DDGS) to be excellent feedstuffs that can lower cost of gain through performance efficiencies and lower ingredient costs. United States swine and poultry producers have also increasingly adopted DDGS in rations in response to higher corn prices, while international shipments of DDGS have also grown.

Three Counties Saw the Majority of Nebraska’s Housing Growth 2007 – 2008

According to estimates released by the Bureau of the Census in August, 2009, Nebraska’s total housing stock increased by 5,529 units between July 1, 2007 and July 1, 2008, an increase of 0.7 percent for the year. This represented an estimated rate of growth in housing stock slightly below the state’s estimated rate of population growth, which was 0.8 percent for the same time period.

Community Life and Housing in Rural Nebraska: 2005 Nebraska Rural Poll Results

Many rural communities are experiencing population decline. However, rural residents have continued to show a strong attachment to their communities. How do rural Nebraskans feel about their community? Are they satisfied with the services provided? Do they own their home? What is the condition of their home? This report details 2,851 responses to the 2005 Nebraska Rural Poll, the tenth annual effort to understand rural Nebraskans’ perceptions. Respondents were asked a series of questions about their community and housing. Trends for some of these questions are examined by comparing data from the nine previous polls to this year’s results. For all questions, comparisons are made among different respondent subgroups, that is, comparisons by age, occupation, region, etc. Based on these analyses, some key findings emerged: Rural Nebraskans’ views of the change in their community are similar to those expressed last year. This year, 28 percent believe their community has changed for the better, compared to 26 percent last year. And, in 2005, only 20 percent think their community has changed for the worse, compared to 22 percent last year. The proportion of expected movers who plan to leave the state decreased this year. Last year, 56 percent of the persons planning to move from their community expected to leave the state. That proportion decreased to 47 percent this year. Rural Nebraskans living in or near the largest communities are more likely than persons living in or near the smaller communities to say their community has changed for the better. Thirty-nine percent of persons living in or near communities with populations of 10,000 or more believe their community has changed for the better during the past year, but only 15 percent of persons living in or near communities with less than 500 people share this opinion. The community services and amenities that rural Nebraskans are most dissatisfied with include: entertainment, retail shopping and restaurants. At least one-third of rural Nebraskans express dissatisfaction with these three services. They are most satisfied with parks and recreation, library services, basic medical care services, highways and bridges, and education (K - 12). At least one-half of rural Nebraskans are satisfied with the following items in their community: appearance of residential areas (66%), crime control (61%), maintenance of sidewalks and public areas (57%) and noise (54%). Rural Nebraskans generally have positive views about their community. Sixty percent agree that their community is an ideal place to live and 52 percent say their community has good business leaders. Rural Nebraskans have mixed opinions about the future of their community. Fortyfour percent agree that their community’s future looks bright, but 42 percent disagree with this statement. Fourteen percent have no opinion. Rural Nebraskans living in or near the larger communities are more likely than residents of the smaller communities to think their community’s future looks bright. Fifty-nine percent of persons living in or near communities with populations of 10,000 or more agree with this statement, compared to only 25 percent of residents living in or near communities with less than 500 people. Further, 61 percent of the residents of the smallest communities disagree with this statement, compared to only 28 percent of the residents of the largest communities. Over three-quarters of rural Nebraskans disagree that younger residents of their community tend to stay there after completing high school. Seventy-six percent disagree with this statement, 16 percent have no opinion and eight percent agree that younger residents stay after completing high school. When comparing responses by age, younger persons are more likely than older persons to agree that younger residents stay in their community after high school. Sixteen percent of persons age 19 to 29 agree with this statement, compared to only six percent of persons age 50 to 64. Younger persons are more likely than older persons to be planning to move from their community next year. Fifteen percent of persons between the ages of 19 and 29 are planning to move next year, compared to only two percent of persons age 65 and older. An additional 17 percent of the younger respondents indicate they are uncertain if they plan to move. Most rural Nebraskans own their home. Eighty-four percent of rural Nebraskans own their home. Older persons are more likely than younger persons to own their home. Eighty-eight percent of persons over the age of 50 own their home, compared to only 52 percent of persons age 19 to 29. Housing in rural Nebraska has an average age of 50 years. Twenty-four percent of residences were built before 1930. Another 24 percent were built between 1930 and 1959. Twenty-nine percent were built between 1960 and 1979 and the remaining 24 percent were built in 1980 or later. The housing stock in smaller communities is older than the housing located in larger communities. Over one-third (35%) of the residences in communities with less than 1,000 people were built before 1930. Only 12 percent of the homes in communities with populations of 10,000 or more were built in this time period. Most rural Nebraskans appear satisfied with their home. Only 24 percent say the current size of their home does not meet their needs. The same proportion (24%) say their home is in need of major repairs. Thirty-eight percent agree that their home needs a lot of routine maintenance, but 87 percent like the location (neighborhood) of their home. One-third of rural Nebraskans living in or near the smallest communities say their home is in need of major repairs. Only 19 percent of persons living in or near communities with populations of 5,000 or more are facing this problem. Home ownership is very important to most rural Nebraskans. Eighty-two percent believe it is very important to own their home. An additional 12 percent say it is somewhat important and six percent say it is not at all important. However, persons who do not currently own their home do not feel it is important for them to do so. Only 32 percent of renters say it is very important to own their home, compared to 91 percent of home owners. And, 35 percent of renters say it is not at all important to own their home.

Thermal efficiency of fiber cement corrugated sheets applied to individual housing for calves exposed to sun and shade

This research presents a study of roof thermal efficiency in individual housing for calves exposed to sun and shade through infrared thermography, internal temperature and thermal comfort indexes. Four different individual housing for calves covered with asbestos-free fiber-cement corrugated sheets were evaluated. Three of them were directly exposed to the sun: (i) corrugated sheets painted white in the external surface, (ii) corrugated sheets without painting and (iii) with screen shade fabric installed 0.10m under de internal surface of the corrugated sheet. The fourth individual housing was installed in the shade area and covered with unpainted corrugated fiber-cement sheets. The analysis was taken for 21 days at 11h00min, 14h00min and 17h00min. The results indicate significant variations in the roofing surface temperature and thermal comfort indexes among the treatments exposed to the sun and shade, for all the evaluations during the day. The infrared thermography images were effective for better understanding the heat transfer processes from the roof to the internal environment of the housing.

Mouse Housing System Using Pressurized Cages Intraventilated by Direct-Current Microfans

We performed the initial assessment of an alternative pressurized intraventilated (PIV) caging system for laboratory mice that uses direct-current microfans to achieve cage pressurization and ventilation. Twenty-nine pairs of female SPF BALB/c mice were used, with 19 experimental pairs kept in Ply cages and 10 control pairs kept in regular filter-top (FT) cages. Both groups were housed in a standard housing room with a conventional atmospheric control system. For both systems, intracage temperatures were in equilibrium with ambient room temperature. PIV cages showed a significant difference in pressure between days 1 and 8. Air speed (and consequently airflow rate) and the number of air changes hourly in the PIV cages showed decreasing trends. In both systems, ammonia concentrations increased with time, with significant differences between groups starting on day 1. Overall, the data revealed that intracage pressurization and ventilation by using microfans is a simple, reliable system, with low cost, maintenance requirements, and incidence of failures. Further experiments are needed to determine the potential influence of this system on the reproductive performance and pulmonary integrity in mice.
