Local Institutions and Better Forests: Empirical Evidence from Household Data

This research aims to enhance informed policy-making and sustainable management of natural resources in Ethiopia through furthering our understanding of the factors that contribute to success (better outcome in forest commons). The research intends to investigate the interplay between the user characteristics, resource characteristics, and the institutional regime as they determine better forest outcome at a more deeper level using household level dataset.

    Sanctioned Quotas vs. Information Provisioning for Community Wildlife Conservation in Zimbabwe: A Framed Field Experiment Approach

    We investigate the behavioural responses of resource users to two policy interventions: sanctioned quotas and information provisioning. We do so in a context in which multiple resources (pastures and wild animal stocks) are connected and could substantially and drastically deteriorate as a result of management. We perform an experimental study among communities that are managing common pool wildlife in Zimbabwe.

    Managing and Defending the Commons: Experimental Evidence from TURFs in Chile

    This work presents the results of framed field experiments designed to study the joint problem of managing harvests from a common pool resource and protecting the resource from poaching. The experiments were conducted both in the field with TURF users and in the lab with university students. Our study has two objectives. First, we designed our experiments to study the effects of poaching on the ability of common pool resource users to coordinate their harvests when encroachment by outsiders is unrestricted and when the government provides weak enforcement.

      The role of institutions in community wildlife conservation in Zimbabwe

      Institutions play a significant role in stabilising large-scale cooperation in common pool resource management. Without restrictions to govern human behaviour, most natural resources are vulnerable to overexploitation. This study used a sample size of 336 households and community-level data from 30 communities around Gonarezhou National Park in Zimbabwe, to analyse the relationship between institutions and biodiversity outcomes in community-based wildlife conservation. Our results suggest a much stronger effect of institutions on biodiversity

      Polycentric governance of multifunctional forested landscapes

      Abstract: Human-induced causes of forest change occur at multiple scales. Yet, most governance mechanisms are designed at a single level – whether international, national, regional or local – and do not provide effective solutions for the overarching challenge of forest governance.

      The Problem of Shared Irresponsibility in International Climate Law

      States have treaty-based and customary international law-based responsibilities to ensure that greenhouse gas emissions emanating from their territory do not cause transboundary harm. However, those international legal responsibilities conflict with the observed behavior of states, which suggests a general rule of irresponsible treatment of the global commons.

      Resistance to the Regulation of Common Resources in Rural Tunisia

      We examine the effect of the introduction of uniform water-charging for aquifer management and provide evidence using a survey-based choice experiment of agricultural water users in rural Tunisia. Theoretically, we show that the implementation of the proposed second-best regulation would result both in efficiency gains and in distributional effects in favour of small landholders. Empirically, we find that resistance to the introduction of an effective water-charging regime is greatest amongst the largest landholders.

      Child Labor, the Wealth Paradox, and Common Forest Management in Bolivia

      That wealthier developing country households may rely more heavily on child labor than poorer households has come to be known as the “wealth paradox.” This paper tests for a wealth paradox with regard to common natural resource wealth by analyzing the relationship between child labor and improved common property forest management (CPFM) in Bolivia.

      Effect of Social Networks on the Economic Performance of TURFs: The Case of the Artisanal Fisherman Organizations in Southern Chile

      The effect of social capital on the economic performance of artisanal  fishermen organizations that work under a Territorial Use Rights in Fisheries (TURF) system was tested using the social networks approach. The application was based on a sample of artisanal fishers organizations that extract the locally named “loco” (Concholepas concholepas) in Central-Southern Chile. Social networks were measured through organizations’ structural properties and their bonding, linking, and bridging relationships. Economic performance was measured through per capita income.

      Extracción de Recursos Naturales en Contextos de Abundancia y Escasez: Un Análisis Experimental sobre Infracciones a Cuotas en Áreas de Manejo y Explotación de Recursos Bentónicos en el Centro-Sur de Chile

      Estudiamos, a través de un experimento económico de campo contextualizado, los efectos de cambios exógenos en los niveles de abundancia de un recurso natural renovable en las decisiones de cumplimiento individual de usuarios operando bajo un régimen de propiedad común y un sistema de derechos de uso territorial pesqueros (DUTPs), que considera cuotas de extracción y fiscalización externa para detectar y sancionar transgresiones.

      Community Controlled Forests, Carbon Sequestration and REDD+ Some Evidence from Ethiopia

      REDD+ (Reduced Emissions from Deforestation and Forest Degradation, “plus” afforestration) is a tool that supports forest carbon-enhancing approaches in the developing world in order to mitigate and hopefully reverse climate change. A key issue within REDD+ is to appropriately bring in the almost 25% of developing country forests that are effectively controlled by communities.

      Regulatory Compliance in Lake Victoria Fisheries

      This analysis of the fishers’ compliance with regulations in Lake Victoria, Tanzania, gives support to the traditional economics-of-crime model and shows that the extension of the basic deterrence model can lead to a richer model with substantially higher explanatory power.

      Can the restrictive harvest period policy conserve mopane worms in Southern Africa? A bio-economic modelling approach

      Imbrasia Belina also known as the mopane worm, like other edible insects and caterpillars, is a vital source of protein to Southern African countries. The worms live and graze on mopane trees, which occupy agricultural land. With increasing commercialization of the worm, the management of the worm, which was hitherto organized as a common property resource, has degraded to a near open access.

      Technical Efficiency and the Role of Skipper Skill in Artisanal Lake Victoria Fisheries

      This paper studies technical efficiency and skipper skill (and explores potential proxies), using Tanzanian fishery data for the two major species, Nile perch and dagaa. The relative level of efficiency is high in both fisheries, and several observable variables linked to skipper skill significantly explain the efficiency level. However, given the rapidly depleting fish stocks in Lake Victoria, increased efficiency at the aggregate level is only possible if fishing effort is limited.

          Water resources management in the Nile basin: the economic value of cooperation

          Since 1999 a multilateral effort termed the Nile Basin Initiative has been underway among the Nile riparians to explore opportunities for maximizing the benefits of the river's waters through cooperative development and management of the basin. However, to date there has been virtually no explicit discussion of the economic value of cooperative water resources development.

            Africa’s International Rivers: An Economic Perspective

            Cooperative management and development of Africa’s international rivers holds real promise for greater sustainability and productivity of the continent’s increasingly scarce water resources and fragile environment. Moreover, the potential benefits of cooperative water resources management can serve as catalysts for broader regional cooperation, economic integration and development—and even conflict prevention. But riparians will pursue joint action only when they expect to receive greater benefits through cooperation than through unilateral action.
