AVALIAÇÃO ECONÔMICA DE SISTEMAS DE IRRIGAÇÃO EM ESTABELECIMENTOS RURAIS FAMILIARES NA REGIÃO OESTE DO PARANÁ  Silvio Cesar Sampaio; Michelle Sato; Elisandro Pires Frigo; Celso Schonwald; Morgana Suszek; Jian Pires FrigoSetor de Recursos Hídricos e Saneamento Ambiental (RHESA), Universidade Estadual do Oeste do Paraná,  Cascavel, PR, [email protected]  1 RESUMO O aumento do custo da terra e dos meios de produção necessários à exploração agrícola não permitem mais que a produção final dependa de fatores climáticos, como um regime de precipitação adequado, devido aos altos custos dos produtos finais. Assim sendo, a tendência do meio empresarial agrícola tem sido o aumento do interesse pela prática da irrigação, que além de reduzir riscos, proporciona outras vantagens significativas ao produtor irrigante. O Instituto Nacional de Colonização e Reforma Agrária (INCRA) e o Fundo das Nações Unidas para a Agricultura e Alimentação (FAO) apresentam dados que revelam que, aproximadamente, 85% do total de propriedades rurais do país são de estabelecimentos rurais familiares, ficando evidente, então, a importância destes agricultores para o setor agropecuário do país. Desta forma, o objetivo deste trabalho foi avaliar a viabilidade econômica de projetos de irrigação implantados em estabelecimentos rurais familiares, voltados à produção de olerícolas, na região oeste do Paraná.A falta de experiência dos produtores com relação à produção de olerícolas foi determinante nos resultados obtidos, gerando produções e produtividades abaixo do esperado, além de valores de TIR e TR que inviabilizaram os projetos. Conclui-se que, apenas nas culturas de morango e tomate, a implantação de sistemas de irrigação, dentro dos mesmos parâmetros de análise deste diagnóstico, foi viável economicamente. UNITERMOS: projetos de irrigação, morango, tomate.  SAMPAIO, S.

ECONOMIC EVALUATION OF IRRIGATION SYSTEMS IN FAMILIAR AGRICULTURAL PROPERTIES IN THE WESTERN REGION OF PARANÁ STATE, BRAZIL  2 ABSTRACT The increase of land cost and the necessary production means of agricultural exploration does not allow, anymore,  the final production dependence on climatic factors,like appropriate  precipitation regimen,  due to the high costs of final products. Thus, the trend in agricultural business has been the increase of interest for irrigation, which, besides reducing risks, provides other significant advantages to the producer. The Instituto Nacional de Colonização e Reforma Agrária (INCRA) and the Foundation of United Nations for Agriculture and Food (FAO) present data that show that, approximately 85% of the total of land properties in this country are familiar agricultural ones, making them important  to the farming sector of the country. Therefore, the objective of this work was to evaluate the economic viability of implanted projects of irrigation in familiar agricultural properties, mainly the olericultural ones in the western region of  Paraná. The producers’ lack of experience with regard to olericultural production was determinant in the obtainedresults, generating productions and yield below the expected ones; moreover, TIR and TR values made the projects impracticable . It may be concluded that, only in the cultures of strawberry and tomatoes, the implantation of irrigation systems, following the same analysis parameters of this diagnosis, were economically  viable. KEY WORDS: irrigation projects, strawberry, tomatoes.

Abstract Background Prior to the first recorded outbreak of Rift Valley fever (RVF) in Uganda, in March 2016, earlier studies done until the 1970’s indicated the presence of the RVF virus (RVFV) in the country, without any recorded outbreaks in either man or animals. While severe outbreaks of RVF occurred in the neighboring countries, none were reported in Uganda despite forecasts that placed some parts of Uganda at similar risk. The Ministry of Agriculture, Animal Industry and Fisheries (MAAIF) undertook studies to determine the RVF sero-prevalence in risk prone areas. Three datasets from cattle sheep and goats were obtained; one from retrospective samples collected in 2010–2011 from the northern region; the second from the western region in 2013 while the third was from a cross-sectional survey done in 2016 in the south-western region. Laboratory analysis involved the use of the Enzyme Linked Immunosorbent Assays (ELISA). Data were subjected to descriptive statistical analyses, including non-parametric chi-square tests for comparisons between districts and species in the regions. Results During the Yellow Fever outbreak investigation of 2010–2011 in the northern region, a total sero-prevalence of 6.7% was obtained for anti RVFV reacting antibodies (IgG and IgM) among the domestic ruminant population. The 2013 sero-survey in the western region showed a prevalence of 18.6% in cattle and 2.3% in small ruminants. The 2016 sero-survey in the districts of Kabale, Kanungu, Kasese, Kisoro and Rubirizi, in the south-western region, had the respective district RVF sero-prevalence of 16.0, 2.1, 0.8, 15.1and 2.7% among the domestic ruminants combined for this region; bovines exhibited the highest cumulative sero-prevalence of 15.2%, compared to 5.3 and 4.0% respectively for sheep and goats per species for the region. Conclusions The absence of apparent outbreaks in Uganda, despite neighboring enzootic areas, having minimal restrictions to the exchange of livestock and their products across borders, suggest an unexpected RVF activity in the study areas that needs to be unraveled. Therefore, more in-depth studies are planned to mitigate the risk of an overt RVF outbreak in humans and animals as has occurred in neighboring countries.
