| Resumo: Este trabalho apresenta a analise da relacao beneficio/custo do manejo em areas de pastagem nativa associadas a producao de ovinos na regiao de caatinga no Nordeste do Brasil. Quatro sistemas de manejo da caatinga foram analisados: caatinga raleada (CR), caatinga raleada e adubada (CRA), caatinga raleada e enriquecida (CRE) e caatinga raleada, enriquecida e adubada (CREA). A analise economica com uso da taxa interna de retorno, do valor presente liquido e do periodo de recuperacao do capital, demonstrou a viabilidade economica dos sistema de manejo quando foi usado o metodo de raleamento da caatinga com adubacao fosfatada e enriquecida com grama Cynodon dactylon (CREA), associado a producao de ovinos, com precos de venda diferenciados em R$ 0,80,... |

| Resumo: O objetivo deste estudo foi realizar uma análise econômica do protocolo de sincronização do estro mais a ração flushing oferecida as cabras durante a estação de monta. Foram selecionadas 12 cabras da raça Saanen e um reprodutor, recebendo ração flushing. Utilizou-se esponjas análogas a progesterona, Prostaglandina e Gonadotrofina Coriônica Equina. O custo total foi de R$ 46, 17/animal. A utilização da sincronização torna-se uma medida viável economicamente quando comparada a monta natural. [Economic analisy on station of sum to Saanen goats using protocol of synchronization of estrous and flushing ration]. Abstract: The aim of the experimente was to realize na economic analysis of protocol synchronization of estrous and flushing ration offered to... |

| Irrigation occupies a central position in China’s crop production. However, due to low per capita water resources, much worse, unevenly distributed over regions and time and the rapid increase of water diversions to non-irrigation sectors, irrigation water shortages have become a very serious problem. Without the adoption of effective measures this problem may even threaten China’s food security. Currently, irrigation efficiency is very low in general, irrigation water prices cannot fully recover water supply costs, and irrigation facilities are aging due to the lack of funding for O&M (operation & maintenance). Since water prices are regulated by the government, and not determined by the market, water prices did not work effectively in water... |

| The Florida Department of Citrus (DOC) is spending public funds to register an abscission agent compound (CMNP) with the U.S. EPA as part of its effort to enhance the private benefits associated with citrus mechanical harvesting. An abscission agent application should allow existing harvesting equipment to operate through the entire late season orange harvesting period. When estimating costs and benefits through 2018, the net present value of mechanically harvesting 25,000 acres is between $60.8 and $79.9 million, depending on price, production, and fruit loss scenarios. For any of the scenarios considered, the discounted value of abscission benefits with mechanical harvesting fully pays for the costs of registration and development within four years. |
