The impact of bifunctional molecules on the gluten network during mixing Inra
Auvergne, R.; Morel, M.H.; Menut, P.; Guilbert, S.; Robin, J.J..
The protein network in gluten was either cross-linked or functionalized by using chain extenders to afford novel bio-based materials. These chain extenders consist on di- or tri- ethylene glycol oligomers functionalized at both end with maleimide or maleate groups and also with commercially available vinyl ether. These bi-functional additives are incorporated into standard gluten/glycerol blends during batch mixing. The gluten polymerization proceeds by thiol/disulfide exchanges during mixing and was assessed by the loss of the soluble fraction of protein in SDS. Modifications of protein size distribution revealed a cross-linking between chain extender and gluten, depending on the reactivity of the terminal functions of the used extender. Maleimide...

Maximum Economic Yield Fishery Management in the Face of Global Warming ArchiMer
Diop, Bassirou; Sanz, Nicolas; Junior Duplan, Yves Jamont; Guene, El Hadji Mama; Blanchard, Fabian; Pereau, Jean-christophe; Doyen, Luc.
This paper deals with fishery management in the face of the ecological and economic effects of global warming. To achieve this, a dynamic bioeconomic model and model-based scenarios are considered, in which the stock's growth function depends on the sea surface temperature. The model is empirically calibrated for the French Guiana shrimp fishery using time series collected over the period 1993–2009. Three fishing effort strategies are then compared under two contrasted IPCC climate scenarios (RCP 8.5 and RCP 2.6). A first harvesting strategy maintains the Status Quo in terms of fishing effort. A more ecologically-oriented strategy based on the closure of the fishery is also considered. A third strategy, which relates to Maximum Economic Yield (MEY), is...

Mangrove increases resiliency of the French Guiana shrimp fishery facing global warming ArchiMer
Diop, Bassirou; Blanchard, Fabian; Sanz, Nicolas.
This paper deals with the biological, ecological and economic impact of global warming and mangrove habitat availability on the French Guiana shrimp fishery. A dynamic bio-economic model is built by employing a shrimp stock's growth function depending on Sea Surface Temperature (SST) and on mangrove surface. The model is empirically calibrated for the French Guiana shrimp fishery using time series collected over 1995–2011. First, two Cobb-Douglas functions, which describe shrimp's natural growth and harvest, are estimated. Then, a Maximum Economic Yield (MEY) harvest rule, based on the optimization of the net present value derived from fishing, is computed. Three management strategies are compared (Closure, Status Quo management, and MEY) under three...

Taxation of a polluting non-renewable resource in the heterogeneous world Inra
Daubanes, J.; Grimaud, A..
This paper extends the literature on the taxation of polluting exhaustible resources by taking international heterogeneities and national tax-setting into account. We propose a two-country Romer model of endogenous growth in which the South is endowed with the stock of an essential polluting non-renewable resource and world economic growth is driven by a northern research sector. We consider the stock of pollution as affecting global welfare. First, we characterize the optimal environmental taxation policies. Second, we examine the impacts of national taxes. Their time profile determines the extraction path, the dynamics of pollution accumulation and that of world output. Their respective levels entail inter-country interactions by altering the efficiency...

West African fish biodiversity reference center: Ghana OceanDocs
Abban, E.K.; Teugels, G.G.; Fermon, V..
Renewable natural resources constitute major sources for socioeconomic development of all developing countries, if they can be con-served, developed and sustainably exploited. For its strategic conservation and sustainable exploitation, biodiversity has to be investigated and documented at various levels and in an internationally accepted manner. However, the human and material resources available in the developing countries are insufficient to under-take the necessary studies, while various forces continue to degrade or erode biodiversity; The obvious solution is through collaboration in research and training.

Influencia social y sostenibilidad en el uso de recursos renovables AgEcon
Almudi, Isabel; Choliz, Julio Sanchez.
En este trabajo presentamos un modelo en el que las actividades extractivas referidas a un recurso natural renovable, si son abusivas, generan algún tipo de reacción social que modifica las preferencias sociales. Esta modificación es tenida en cuenta por el planificador a la hora de decidir cual es la asignación intertemporal óptima entre consumo y stock del recurso. Bajo estas nuevas condiciones, nos preguntamos cómo cambia el stock del recurso natural en el estado estacionario y qué puede decirse acerca de la posibilidad de sobreexplotación en comparación con los modelos tradicionales en los que no se considera reacción social. Los resultados obtenidos muestran que bajo estas nuevas condiciones el stock del estado estacionario aumenta y el comportamiento...

Absolute Abundance and Relative Scarcity: Announced Policy, Resource Extraction, and Carbon Emissions AgEcon
Di Maria, Corrado; Smulders, Sjak; van der Werf, Edwin.
We study the effectiveness of climate change policy in a model with multiple non-renewable resources that differ in their carbon content. We find that, when allowing some time between announcement and implementation of a cap on carbon dioxide emissions, emissions from non-renewable energy sources increase at the time of announcement. There are two channels behind this effect. First, since a binding constraint on emissions restricts energy use during some period of time, more must be extracted during other periods. Second, since low carbon energy sources are relatively more valuable when the policy is implemented, it is optimal to conserve them ahead of enforcement. This might induce a...

Grazing Fees versus Stewardship on Federal Lands AgEcon
Watts, Myles J.; Shimshack, Jay P.; LaFrance, Jeffrey T..
Livestock grazing on public lands continues to be a source of intense conflict and debate. We analyze this problem using a dynamic game. Low grazing fees let ranchers capture more rent from grazing. This increases the incentive to comply with federally mandated regulations. Optimal grazing contracts therefore include grazing fees that are lower than competitive private rates. The optimal policy also includes random monitoring to prevent strategic learning by cheating ranchers and avoid wasteful efforts to disguise noncompliant behavior. Finally, an optimal policy includes a penalty for cheating beyond terminating the lease. This penalty must be large enough that the rancher who would profit the most from cheating experiences a negative expected net return.

Dynamics of Spatial Exploitation: A Metapopulation Approach AgEcon
Sanchirico, James N.; Wilen, James E..
We present a bioeconomic model of a harvesting industry operating over a heterogeneous environment comprised of discrete biological populations interconnected by dispersal processes. The model generalizes the H. S. Gordon [1954]/V. Smith [1968] model of open-access rent dissipation by accounting for intertemporal and spatial "Ricardian" patterns of exploitation. This model yields a simple, but insightful, framework from which one can investigate factors that contribute to the evolution of resource exploitation patterns over space and time. For example, we find that exploitation patterns are driven by biological and fleet dispersal and biological and economic heterogeneity. We conclude that one cannot really understand the biological processes operating in...

Policy Endogeneity and the Effects of Trade on the Environment AgEcon
Copeland, Brian R..
This paper reviews recent work on the implications of endogenous policy for the effects of trade on the environment and the sustainability of renewable resource stocks. A recognition that pollution policy is endogenous has had a major impact on the trade and environment literature and has reversed some of the previously established empirical findings. Work on pollution has proceeded faster than work on renewable resources. I suggest some directions for future work in this area.
