“…For instance, oppressive state control and rent seeking behaviour can put the resource base at risk (Benjaminsen et al, 2013). Further, essential research on attributes of property rights would contribute to sustainability of biological resources (Diekert, 2012;Nkhata et al, 2012). As the tragedy of the commons is increasingly part of the conventional wisdom in environmental studies, economics and ecology (McEvoy, 1988;Leach and Mearns 1996), results and lessons from the tragedy of commons could proof relevant in the formulation of strategies and policies for sustainable natural resource management.…”

Natural resources degradation threatens persistence of biological resources in many parts of Eastern and Southern African regions. In these regions, property rights regimes intractably influence resource utilisation and biodiversity conservation. Hitherto, the underlying causes of varied performances of property rights regimes are rarely collated. Consequently, resource policies are often flawed, resulting in pervasive systems failure and biodiversity losses. In this study, this particular information gap is interrogated by systematically reviewing various property rights regimes, their influence on resource utilisation and biodiversity conservation from wealthy of available literature. The results unravelled that the performance of various property rights regimes are influenced by levels of social capital, encompassing stakeholders' participation, trust, commitment and social networking at the base regardless of whether the property rights areby full hegemony or sanctioned by higher authorities.This findingcloselyapproximatestheconceptofenvironmentalsubsidiarityinnaturalresourcemanagement.Furth er, it is concluded that bottom-up self-institutional regulation and top-down state controlplay complimentary if not invasive role to each other. These approaches stimulate sustainable resource utilisation and biodiversity conservation, where legal actors are given full resource property rights to access, own, utilise and exclude intruders to avoid the 'tragedy of the commons'.

“…Recent research, however, is unraveling the rent dissipation process, revealing the multiple dimensions where it occurs, such as space, age or size, habitat, genetic diversity, etc. (see Abbott and Wilen, 2011;Smith, 2012;Reimer et al, 2014;Diekert, 2012).…”

a b s t r a c tFishing impacts biodiversity on multiple levels, potentially resulting in unintended feedbacks to the economic performance of the fishery over time. For example, targeting observable traits within a population can impact genetic diversity and targeting valuable species can impact biodiversity at the ecosystem level. The bioeconomic literature, however, has given little attention to the effect of fishing on population diversity, even though population diversity contributes to ecosystem services and estimates of population extinction rates are three orders of magnitude higher than species extinction rates. Here we develop a stochastic bioeconomic model that links the harvest of multiple salmon populations in a single commercial fishery to the trajectory of population diversity in a salmon stock complex. We parameterize our model with biological and economic data from the Copper River Chinook salmon fishery. We show that markets can incentivize the degradation of population diversity, reducing infra-marginal fishery rents, and increasing variability in economic returns. We also show that second-best management can conserve population diversity and improve welfare. Furthermore, depending on fishermen's time preferences, this management strategy is potentially self-financing.

“…Second, both biologists (Almroth et al 2012) and economists (Diekert 2012 andQuaas et al 2010) have recently called for new regulation where age and size of fish are taken into account.…”

“…Recently, more realistic age-structured models have been developed, see e.g., Diekert (2012), Tahvonen (2009) or Quaas et al (2010). Based on the findings in these papers, the authors call for regulation based on age-structured models rather than traditional biomass models.…”

Terms of use: Documents in AbstractThe importance of fish size for price per kilo is studied using an inverse demand approach. Prices per kilo in different size categories of the same species differ significantly. This means that the average price for a species may change due to e.g., high-grading, growth overfishing or a changing climate which all have the potential to change the size composition of the catch. The estimates show that quantity flexibilities differ substantially across size and species while scale flexibilities in general are close to homothetic. The results imply that the effect of size on price is an important aspect to take into account when formulating regulation or policies to curb growth overfishing and high-grading.
