A nivel mundial, la utilización eficiente del agua en la producción agrícola sólo se puede lograr cuando se planifica el proyecto de riego, con un diseño que permita opera el recurso, con el fin de atender en cantidad y tiempo, las necesidades de agua de un cultivo, para un crecimiento óptimo y altos rendimientos. Lo que implica realizar un adecuado diseño del sistema de riego, donde en la actualidad existen varios software para el diseño de sistemas de riego, todos ellos siendo de gran aceptación por su versatilidad y facilidad de manejo y el poco tiempo que se emplea para realizar los diseños. Sin embargo todos y cada uno de ellos tienen su sustento en los procedimientos y métodos de cálculo manual que se han desarrollado a lo largo de la historia. El... |

Concerned decision makers increasingly pose questions as to whether current management practices are able to cope with climate change and increased climate variability. This signifies a shift in the framing of climate change from asking what its potential impacts are to asking whether it induces policy failure and unacceptable change. In this paper, we explore the background, feasibility, and consequences of this new framing. We focus on the specific situation in which a social-political threshold of concern is likely to be exceeded as a result of climate change, requiring consideration of alternative strategies. Action is imperative when such a situation is conceivable, and at this point climate change becomes particularly relevant to decision makers. We... |

Adverse impacts of marine litter is documented on >1400 species, including marine megafauna (fish, birds, sea turtles and mammals). The primary impacts include ingestion and entanglement, and there is increasing concern about chemical contamination via ingestion. Numerous survey approaches and monitoring programs have been developed and implemented around the world. They may aim to provide data about parameters such as species distribution and interactions with anthropogenic activities. During the Sixth International Marine Debris Conference, a session was dedicated to the tools and constraints in monitoring interactions between litter and megafauna. In the present paper, we summarize 7 case studies which discuss entanglement and ingestion including... |

To attain sustainable development in the 21st century, the world's population still has to overcome many challenges; hunger, poverty, environmental degradation and depletion. Policy design in such a context is and will remain a complex task. On one hand, policy makers often lack information on stakeholders' strategies and constraints as well as on potential options for improvement. On the other hand, stakeholders do not always adhere to policies for lack of understanding of the pursued goals. It is not unusual to observe that often, real policy effects are not those initially expected. Furthermore, existing decision-making mechanisms for public intervention are increasingly questioned due to pressure for market liberalization, decentralization processes... |

Farm risk management for income stabilization is on-going issue. An applied work has been performed to measure farm risk using a stochastic model. Risk management tools, with symmetric as well as asymmetric impacts, are then tested and compared through ad hoc statistics. Normal farm business risk can be efficiently managed using a precautionary saving provision. Farm revenue insurance is found as the most efficient asymmetric tool for dealing with climatic and market shocks. The linkage between these complementary tools can be adjusted upon market environment. |
