TL;DR: In this article, a statistical analysis carried out for oil spillage quantities and incidence between 1976-2000, showed a decrease in the amount of oil spilled and an increase in the number of oil spillages.
Abstract: Colonel Drake drilled a 70 feet well in Titusville, Pennsylvania and discovered oil. In 1956, Shell British Petroleum discovered crude oil in the Niger Delta within Nigeria and since then oil exploration and exploitation have been ongoing for several decades. The Niger Delta consists of highly diverse ecosystems supportive of numerous species of terrestrial and aquatic fauna and flora and is the largest wetland in Africa. The oil spillages ongoing for several decades have characterized the area by contaminated rivers, stream and forest, which constitutes the major income source for the majority of the local population inhabiting the region, which are mainly dependent on ecosystem services. Approximately 1.5 million tons of oil has been spilled within the Niger Delta region over the span of several decades, most of which was partially cleaned or not cleaned totally, making some areas wastelands. Statistical analysis carried out for oil spillage quantities and incidence between 1976-2000, showed decrease in oil spillage quantity and increase in oil spillage incidence. These results were based on figures the oil companies submit to the government and one would not expect them to represent the actual figures. Reliable data could not be obtained for the most recent spills, more extensive evaluation is required. Keywords: Oil, Spillage, Niger Delta, Nigeria

TL;DR: In this article, food loss and waste can contribute to food security and sustainability through measuring food loss, identifying where in the food system it occurs, and developing effective policies along the value chain.
Abstract: Reducing food loss and waste can contribute to food security and sustainability. Measuring food loss and waste, identifying where in the food system it occurs, and developing effective policies along the value chain are essential first steps toward addressing the problem.

TL;DR: In this paper, a detailed review of different approaches to model the HPF is presented, and a new four-dimensional piecewise linear model is proposed, taking into account the water head as a function of forebay and tailrace levels and considering spillage effects.
Abstract: The generation of a hydroelectric plant is a nonlinear function of the turbined outflow, storage and sometimes also of the spillage. Other aspects, such as forbidden operating zones and individual turbine efficiency curves, are also important. Although for the self-scheduling of a hydro plant a precise integer modeling of the hydro power production function (HPF) is convenient, in the security constrained short-term hydrothermal dispatch problem for large-scale systems a strategy which best balances an accurate representation with an acceptable computational burden is required. In this paper, a detailed review of different approaches to model the HPF is presented, and a new four-dimensional piecewise linear model is proposed. This model takes into account the water head as a function of forebay and tailrace levels and considers spillage effects. Nonconcave regions of the HPF are approximated by using convexification and regression techniques. A major advantage of this approach is to consider the influence of storage, turbined outflow and spillage in a single function that can be used in a straightforward way, instead of deriving several curves for different heads. Numerical results show the applicability of this approach to the day-ahead network constrained short-term hydrothermal dispatch problem of the large Brazilian system.
