RESUMEN

Most countries have many pieces of legislation that govern biodiversity, including a range of criminal, administrative, and civil law provisions that state how wildlife must be legally used, managed, and protected. However, related debates in conservation, such as about enforcement, often overlook the details within national legislation that define which specific acts are illegal, the conditions under which laws apply, and how they are sanctioned. Based on a review of 90 wildlife laws in 8 high-biodiversity countries with different legal systems, we developed a taxonomy that describes all types of wildlife offenses in those countries. The 511 offenses are organized into a hierarchical taxonomy that scholars and practitioners can use to help conduct legal analyses. This is significant amidst competing calls to strengthen, deregulate, and reform wildlife legislation, particularly in response to fears over zoonotic threats and large-scale biodiversity loss. It can be used to provide more nuance legal analyses and facilitate like-for-like comparisons across countries, informing processes to redraft conservation laws, review deregulation efforts, close loopholes, and harmonize legislation across jurisdictions. We applied the taxonomy in a comparison of sanctions in 8 countries for hunting a protected species. We found not only huge ranges in fines (US$0 to $200,000) and imprisonment terms (1.5 years to life imprisonment), but also fundamentally different approaches to designing sanctions for wildlife offenses. The taxonomy also illustrates how future legal taxonomies can be developed for other environmental issues (e.g., invasive species, protected areas).


Creación de una Taxonomía Mundial de Ofensas a la Fauna Resumen La mayoría de los países tienen muchos instrumentos de legislación que gobiernan la biodiversidad, incluyendo una gama de disposiciones de leyes criminales, administrativas y civiles que declaran cómo se debe usar, manejar y proteger legalmente a la fauna. Sin embargo, los debates relacionados a la conservación, como el cumplimiento de las leyes, generalmente ignoran los detalles dentro de la legislación nacional que definen cuáles actos específicos son ilegales, las condiciones bajo las cuales aplican las leyes y cómo son sancionadas. Con base en una revisión de 90 leyes relacionadas con la fauna en ocho países con una gran biodiversidad y diferentes sistemas legales, desarrollamos una taxonomía que describe todos los tipos de ofensas a la fauna en aquellos países. Las 511 ofensas están organizadas en una taxonomía jerárquica que los académicos y los practicantes pueden usar para ayudar a realizar análisis legales. Lo anterior es significativo en medio de las peticiones competitivas por fortalecer, desregular y reformar la legislación de la fauna, particularmente como respuesta al miedo por las amenazas zoonóticas y la pérdida a gran escala de la biodiversidad. La taxonomía puede usarse para proporcionar análisis legales más matizados y para facilitar las comparaciones igual-por-igual entre los países, informar los procesos para reformular las leyes de conservación, revisar los esfuerzos por desregular, cerrar los vacíos legales y armonizar la legislación entre las jurisdicciones. Aplicamos la taxonomía en una comparación de las sanciones aplicadas en ocho países a la caza de especies protegidas. Encontramos no sólo una gama enorme de multas (de US$0 a $200,000) y términos de encarcelamiento (de 1.5 años a sentencias de por vida), sino también estrategias fundamentalmente diferentes para el diseño de las sanciones para las ofensas a la fauna. La taxonomía también ilustra cómo pueden desarrollarse las siguientes taxonomías legales para otros temas ambientales (p. ej.: especies invasoras, áreas protegidas).

RESUMEN

The dominant approach to combating the illegal wildlife trade has traditionally been to restrict the supply of wildlife products. Yet conservationists increasingly recognize the importance of implementing demand-side interventions that target the end consumers in the trade chain. Their aim is to curb the consumption of wildlife or shift consumption to more sustainable alternatives. However, there are still considerable knowledge gaps in understanding of the diversity of consumer motivations in the context of illegal wildlife trade, which includes hundreds of thousands of species, different uses, and diverse contexts. Based on consultation with multiple experts from a diversity of backgrounds, nationalities, and focal taxa, we developed a typology of common motivations held by wildlife consumers that can be used to inform conservation interventions. We identified 5 main motivational categories for wildlife use: experiential, social, functional, financial, and spiritual, each containing subcategories. This framework is intended to facilitate the segmentation of consumers based on psychographics and allow the tailoring of interventions-whether behavior change campaigns, enforcement efforts, or incentive programs-to the specific context in which they will be used. Underlining the importance of consumer research and collaborating with local actors is an important step toward promoting a more systematic approach to the design of demand reduction interventions.


Motivaciones para el Uso y Consumo de Productos de Fauna Resumen Tradicionalmente, la estrategia dominante para combatir el mercado ilegal de fauna ha sido restringir la oferta de productos de fauna. Aun así, los conservacionistas cada vez reconocen más la importancia de implementar intervenciones por el lado de la demanda que se enfoquen en los consumidores finales en la cadena de mercado. Su objetivo es reducir el consumo de fauna o redirigir ese consumo hacia alternativas más sustentables. Sin embargo, todavía existen vacíos de conocimiento en el entendimiento de la diversidad de motivos para los consumidores dentro del contexto del mercado ilegal de fauna, el cual incluye cientos de miles de especies, diferentes usos y contextos diversos. Con base en consultas a varios expertos con una diversidad de antecedentes, nacionalidades y taxones de enfoque desarrollamos una tipología de motivos comunes que tienen los consumidores de fauna que pueden usarse para orientar las intervenciones de conservación. Identificamos cinco categorías principales de motivos para el uso de fauna: vivencial, social, funcional, financiero y espiritual, cada uno con subcategorías. Este marco de trabajo tiene la intención de facilitar la segmentación de consumidores con base en psicográficos y permitir la personalización de las intervenciones - sean campañas de cambios en el comportamiento, esfuerzos por hacer cumplir las reglas o programas de incentivos - al contexto específico en el que serán utilizadas. Resaltar la importancia de los estudios de mercado y la colaboración con los actores locales es un paso importante hacia la promoción de una estrategia más sistemática para el diseño de intervenciones para reducir la demanda.

RESUMEN

Political and economic transitions have had substantial impacts on forest conservation. Where transitions are underway or anticipated, historical precedent and methods for systematically assessing future trends should be used to anticipate likely threats to forest conservation and design appropriate and prescient policy measures to counteract them. Myanmar is transitioning from an authoritarian, centralized state with a highly regulated economy to a more decentralized and economically liberal democracy and is working to end a long-running civil war. With these transitions in mind, we used a horizon-scanning approach to assess the 40 emerging issues most affecting Myanmar's forests, including internal conflict, land-tenure insecurity, large-scale agricultural development, demise of state timber enterprises, shortfalls in government revenue and capacity, and opening of new deforestation frontiers with new roads, mines, and hydroelectric dams. Averting these threats will require, for example, overhauling governance models, building capacity, improving infrastructure- and energy-project planning, and reforming land-tenure and environmental-protection laws. Although challenges to conservation in Myanmar are daunting, the political transition offers an opportunity for conservationists and researchers to help shape a future that enhances Myanmar's social, economic, and environmental potential while learning and applying lessons from other countries. Our approach and results are relevant to other countries undergoing similar transitions.

RESUMEN

The supposition that agricultural intensification results in land sparing for conservation has become central to policy formulations across the tropics. However, underlying assumptions remain uncertain and have been little explored in the context of conservation incentive schemes such as policies for Reducing Emissions from Deforestation and forest Degradation, conservation, sustainable management, and enhancement of carbon stocks (REDD+). Incipient REDD+ forest carbon policies in a number of countries propose agricultural intensification measures to replace extensive "slash-and-burn" farming systems. These may result in conservation in some contexts, but will also increase future agricultural land rents as productivity increases, creating new incentives for agricultural expansion and deforestation. While robust governance can help to ensure land sparing, we propose that conservation incentives will also have to increase over time, tracking future agricultural land rents, which might lead to runaway conservation costs. We present a conceptual framework that depicts these relationships, supported by an illustrative model of the intensification of key crops in the Democratic Republic of Congo, a leading REDD+ country. A von Thünen land rent model is combined with geographic information systems mapping to demonstrate how agricultural intensification could influence future conservation costs. Once postintensification agricultural land rents are considered, the cost of reducing forest sector emissions could significantly exceed current and projected carbon credit prices. Our analysis highlights the importance of considering escalating conservation costs from agricultural intensification when designing conservation initiatives.

RESUMEN

Policy makers across the tropics propose that carbon finance could provide incentives for forest frontier communities to transition away from swidden agriculture (slash-and-burn or shifting cultivation) to other systems that potentially reduce emissions and/or increase carbon sequestration. However, there is little certainty regarding the carbon outcomes of many key land-use transitions at the center of current policy debates. Our meta-analysis of over 250 studies reporting above- and below-ground carbon estimates for different land-use types indicates great uncertainty in the net total ecosystem carbon changes that can be expected from many transitions, including the replacement of various types of swidden agriculture with oil palm, rubber, or some other types of agroforestry systems. These transitions are underway throughout Southeast Asia, and are at the heart of REDD+ debates. Exceptions of unambiguous carbon outcomes are the abandonment of any type of agriculture to allow forest regeneration (a certain positive carbon outcome) and expansion of agriculture into mature forest (a certain negative carbon outcome). With respect to swiddening, our meta-analysis supports a reassessment of policies that encourage land-cover conversion away from these [especially long-fallow] systems to other more cash-crop-oriented systems producing ambiguous carbon stock changes - including oil palm and rubber. In some instances, lengthening fallow periods of an existing swidden system may produce substantial carbon benefits, as would conversion from intensely cultivated lands to high-biomass plantations and some other types of agroforestry. More field studies are needed to provide better data of above- and below-ground carbon stocks before informed recommendations or policy decisions can be made regarding which land-use regimes optimize or increase carbon sequestration. As some transitions may negatively impact other ecosystem services, food security, and local livelihoods, the entire carbon and noncarbon benefit stream should also be taken into account before prescribing transitions with ambiguous carbon benefits.
