Marques, Érika Tavares ; Gunkel, Günter ; Sobral, Maria Carmo (2019-06-04)

Due to global warming, a reduction in available water will occur in many watersheds and conflicts concerning water use will take place. This situation is already typical in semi-arid areas, where many reservoirs have been constructed for water storage. Increased energy demands and climate change have led to severe and increasing pressure on aquatic systems. Today, the environmental policies of ...

Data for Fish Stock Assessment Obtained from the CMSY Algorithm for all Global FAO Datasets

Hélias, Arnaud (2019-05-24)

Assessing the state of fish stocks requires the determination of descriptors. They correspond to the absolute and relative (to the carrying capacity of the habitat) fish biomasses in the ecosystem, and the absolute and relative (to the intrinsic growth rate of the population) fishing mortality resulting from catches. This allows, among other things, to compare the catch with the maximum sustain...
