| The Rio Grande has headwaters in Colorado, flows through New Mexico, and serves as the United States.–Mexico border in Texas, emptying into the Gulf of Mexico. Snow melt in Colorado and northern New Mexico constitutes the water river supply for New Mexico and the El Paso region, whereas summer monsoonal flow from the Rio Conchos in Mexico and tributaries, including the Pecos River, provides the Rio Grande flow for southern Texas. The region is mostly semiarid with frequent long-term drought periods but is also characterized by a substantial irrigated agriculture sector and a rapidly growing population. International treaties and interstate compacts provide the rules for allocation of Rio Grande waters between the United States and Mexico and among... |

| Coastal resource utilization and management systems, bothtraditional and more recently conceived, were studied in Mecufidistrict, northern Mozambique in a post-conflict situation prior towhich a significant migration of people to the coast had occurred.A wide variety of coastal biotopes containing a multitude ofresources had been affected in various ways. Intertidalorganisms exhibited signs of decreasing abundance and averagesize, whereas offshore fishes and mangrove forests did not showsigns of overutilization. It was observed that traditional coastalmanagement systems were still influential, but that newerinitiatives were only beginning to enter into significant dialogueand cooperation with these. In the current circumstances ofpeace and political... |

| The objectives of marine protected areas (MPA), such as Reunion’s Marine Reserve founded in 2007, are (i) protect habitats (ecosystems) and resources (biodiversity) from increasing pressure due to a major urban, economic and recreational development; ii) manage uses and conflicts between traditional fisheries, spear-fishing, diving and recreational activities inside the coastal zone. These goals necessitate monitoring tools such as indicators and diagnostics. The PAMPA programme involves seven MPA including the Natural Marine Reserve of La Reunion (RNMR). It aims for each site to identify and validate indicators according to management objectives and group them in a MPA performance dashboard. This panel will help to visualize temporal trends and define... |

| During the last SCRS plenary meeting, the sub-committee on environment suggested to present a document on the ‘Ecosystem Approach to Fisheries’ (EAF). This document firstly recalls the general scientific and institutional background of EAF, then we propose a synoptic view of EAF, including four main domains: governance, exploitation, resources and impacts on ecosystems. The way that EAF is tackled within the various tuna commissions is then summarised. Finally, we rapidly examine the way the SCRS could cope with EAF issues and we suggest to merge the sub-committee on environment with this on by-catch into a single subcommittee on ecosystem. |

| This communication aims at the analysis of the construction process of territorial resources which allowed the local system of production / processing of shallot to remain on the Dogon plateau. Complex resources, putting in relation specific know-how and local organizational and institutional devices carried the development of this production and conferred it a certain specificity, recognized by the consumers. It was so able to resist to the new competitions, national, then international. The interest and feasibility of the recording of this product as Geographical Indication is questioned nowadays. If this project can allow opening new markets, fighting against phenomena of usurpation and strengthening local organizations, it is raising the issue of the... |

| Marion Clawson passed away in April 1998 at the age of 92. He was a giant in the field of resource and environmental economics who devoted the last decade and one-half of his professional career to forest and forest related issues. He produced over 30 professional books and hundreds of papers. This paper presents a broad overview of his career as an economist, with a focus on his work in and influence on forestry and forest policy. From the early 1970s through to his last professional book in 1983, and his final professional contributions in the mid 1990s, Clawson devoted most of his professional efforts to forest issues. His influence on forests and forest policy was substantial, especially in the context of public policy toward America's publicly owned... |

| The habitat use and feeding habits of a set of nektonic fish species often found in small low-gradient streams in Brazil were investigated. The core species in the present study was Knodus moenkhausii (Eigenmann & Kennedy, 1903), the most abundant of five species in the nektonic guild. Records of the species in 22 streams indicate that K. moenkhausii is associated, on a mesohabitat scale, with runs, and on a microhabitat scale, with sandy bottoms, intermediate depth, and open sites without coverage or submerged vegetation. During snorkeling observations, two additional nektonic registered species showed spatial segregation from K. moenkhausii with respect to foraging microhabitats. Feeding habits of the observed nektonic species were significantly... |

| Textbooks in agricultural economics characterize resources used in production agriculture into four categories: land, labor, capital, and entrepreneurial ability. Profit is presented as earned by management. This traditional list of resources is respecified. Management is redefined as a specialized type of labor and two additional resources, information and risk bearing capacity, are added. Profits accrue not to management but to those able to bear the risk inherent in production agriculture. Equity diversification is a means for farmers to provide and manage this resource and, thus, earn economic profits. Producer education and the repeal or amendment of legislation restricting the ability of farmers to diversify their equity investment are needed. |

| We review and compare four broad categories of spatially-explicit modelling approaches currently used to understand and project changes in the distribution and productivity of living marine resources including: 1) statistical species distribution models, 2) physiology-based, biophysical models of single life stages or the whole life cycle of species, 3) food web models, and 4) end-to-end models. Single pressures are rare and, in the future, models must be able to examine multiple factors affecting living marine resources such as interactions between: i) climate-driven changes in temperature regimes and acidification, ii) reductions in water quality due to eutrophication, iii) the introduction of alien invasive species, and/or iv) (over-)exploitation by... |
