Conservation and prioritization of indigenous vegetables in the Philippines
Nutrition-related problems are a widespread challenge in the Philippines. Many factors contribute to these problems - the availability and affordability of vegetables, for example, which are jeopardized by challenges such as seasonality and inconsistent yields due to the impacts of climate change. Crop improvement and on-farm diversification, particularly using indigenous vegetables (IVs), can help address these challenges, while also improving rural livelihoods, nutrition, and food security; and even safeguarding local culture and tradition

Temperaturas de acionamento de sistemas de climatização para perus em épocas de baixa umidade relativa do ar Activating temperatures of ventilation systems for turkeys in low humidity periods
Este estudo teve o objetivo de avaliar distintos programas de acionamento dos sistemas de climatização (ventiladores e nebulizadores), visando a aprimorar o ambiente interno e o bemestar das aves, evitando possĂveis perdas produtivas e gastos excessivos em energia elĂ©trica. O estudo foi conduzido em dois aviários localizados no municĂpio de Uberlândia - MG, durante a Ă©poca de baixa umidade relativa do ar (junho a dezembro). Os aviários foram comparados sob os parâmetros de concentrações de CO2, temperatura e umidade relativa do ar, temperatura superficial da cama e Ăndices produtivos. Os dados climáticos foram submetidos Ă análise de variância, e os dados produtivos submetidos ao teste de Qui-quadrado, utilizando-se do software MINITAB V.14. Os resultados apontados pelos tratamentos 1 e 2 mostraram que as concentrações de CO2 no ar (372,70 e 379,46 ppm, respectivamente) estiveram abaixo dos limites máximos recomendados internacionalmente para ambos os sistemas. As temperaturas internas (26,23 e 26,56 ÂşC, respectivamente) estiveram sempre acima do recomendado para as aves, e os nĂveis de umidade relativa do ar (69,73 e 70,42, respectivamente) estiveram, em mĂ©dia, na faixa recomendada, para ambos os sistemas. Conclui-se que o aviário programado para acionar o sistema de climatização mais tardiamente consumiu menos energia elĂ©trica, apresentou melhor conversĂŁo alimentar, menor incidĂŞncia de artrite, porĂ©m maior percentual de mortalidade.<br>This study aimed to evaluate different turn on systems of climatization (fans and fogging sprinklers) to improve the internal environment and the birds' welfare, avoiding productive losses and expensive wastes in electrical energy. The study was conducted in a commercial property with two poultry houses, located in Uberlândia, MG, Brazil, during the phase of low relative humidity of the air (June to December). The poultry houses were compared under the parameters of concentration of CO2, temperature and relative humidity, surface temperature of the litter and production indexes. The climatic data were subjected to analysis of variance and productive data submitted to chi-square, using the software Minitab, V.14. The results showed in treatments one and two that concentrations of CO2 in the air (372,70 and 379,46 ppm, respectively) were below the internationally recommended limits for both systems. The internal temperatures (26,23 e 26,56 ÂşC, respectively) were always above the recommended for birds, and the levels of relative humidity (69,73 e 70,42, respectively) were on average in the recommended range for both systems. The conclusion is that the poultry house programmed to trigger the air-conditioning later, consumed less electricity, had better feed conversion, lower incidence of arthritis, but a higher percentage of mortality
