COVID-19, systemic crisis, and possible implications for the wild meat trade in sub-Saharan Africa

Wild animals play an integral and complex role in the economies and ecologies of many countries across the globe, including those of West and Central Africa, the focus of this policy perspective. The trade in wild meat, and its role in diets, have been brought into focus as a consequence of discussions over the origins of COVID-19. As a result, there have been calls for the closure of China’s “wet markets”; greater scrutiny of the wildlife trade in general; and a spotlight has been placed on the potential risks posed by growing human populations and shrinking natural habitats for animal to human transmission of zoonotic diseases. However, to date there has been little attention given to what the consequences of the COVID-19 economic shock may be for the wildlife trade; the people who rely on it for their livelihoods; and the wildlife that is exploited. In this policy perspective, we argue that the links between the COVID-19 pandemic, rural livelihoods and wildlife are likely to be more complex, more nuanced, and more far-reaching, than is represented in the literature to date. We develop a causal model that tracks the likely implications for the wild meat trade of the systemic crisis triggered by COVID-19. We focus on the resulting economic shockwave, as manifested in the collapse in global demand for commodities such as oil, and international tourism services, and what this may mean for local African economies and livelihoods. We trace the shockwave through to the consequences for the use of, and demand for, wild meats as households respond to these changes. We suggest that understanding and predicting the complex dynamics of wild meat use requires increased collaboration between environmental and resource economics and the ecological and conservation sciences

Essai de lutte intégrée contre la prolifération de Cissus quadrangularis L. (Vitaceae) dans le Parc National des Iles de la Madeleine (Sénégal)

Objectif : contribuer à mettre en place une lutte intégrée contre la prolifération de Cissus quadrangularis L. dans le Parc National des Iles de la Madeleine (PNIM) au Sénégal.Méthodologie et résultats : Des essais de contrôle biologique et physique ont été testés. La lutte biologique a été basée sur la collecte et l’élevage en laboratoire de chenilles capables de dégrader les tiges et les feuilles de C. quadrangularis. Quant à la lutte physique, elle a consisté à arracher les individus de l’espèce et à suivre la capacité de régénération des résidus de la plante après différents traitements. Les résultats obtenus ont montré qu’une lutte biologique est envisageable à travers la chenille de   Hippotion celerio, phytophage de C. quadrangularis. Aussi, les tests de contrôle physique ont montré que l’arrachage manue  semblerait être efficace quand les fragments de la plante sont éliminés par  incinération hors du parc.Conclusion et application: La combinaison de ces deux méthodes pourrait permettre de réduire et de limiter la superficie d’occupation de C. quadrangularis dans le PNIM.Mots clés: Cissus quadrangularis, plante proliférante, Parc National des Iles de la Madeleine, lutte physique, lutte biologique, Hippotion celerio.Introduction: Help put up a integrated fight against the proliferation of Cissus quadrangularis L. in the National Park des Iles de la Madeleine (NPIM) in Senegal.Methodology and results: of trying to biological and physical control. Biological control has been based on collecting and raising caterpillars capable of degrading the stems and leaves of the concern species. As for the physical struggle, it was to snatch individuals of C. quadrangularis and follow the regenerative capacity of the plant residues after different treatments. The results have shown that biological control is possible through the caterpillar of Hippotion celerio, phytophage of C. quadrangularis. Also, physical control tests have shown that manual eradication would seem to be effective when the fragments of the plant are disposed of by incineration out of the park.Conclusion and application: The combination of these two methods could reduce and limit the occupancy area and possible spread of C. quadrangularis in NPIM.Keywords: Cissus quadrangularis, Alien plants, National Park des Iles de la Madeleine, physical control, biological control, Hippotion celerio

Putting conservation efforts in Central Africa on the right track for interventions that last

Interventions in Africa designed to stop biodiversity decline have often failed because they were based on a top-down approach to management and focused on enforcing restrictive rules and imposing bans. They were equally misaligned with the values and needs of local actors. This paper presents an African perspective on the discourse regarding the bushmeat crisis and shows that bushmeat in Africa goes beyond being a source of livelihood, having a multifaceted use that must be considered when designing interventions. We show that current conservation initiatives often do not address the right issues, by neglecting nonmonetary dimensions of bushmeat use, inadequately planning interventions, failing to align wildlife laws with realities on the ground, and carrying out ineffective law enforcement characterized by poor governance and corruption. We recommend a revision of current legal frameworks to enhance local ownership, tenure rights, and the sustainable economic empowerment of local communities to reduce hunting. We also call for development of regionally led innovative programs that invest in nature-based solutions and payments for environmental services. Finally, we identify where more research is needed to understand why wildlife use in Africa is overlooked in national development policies and not considered in national accounting

The role of environmental factors in promoting and limiting biological invasions in South Africa

A number of key points arise from this review. Since 1913, South Africa has been one of a few countries that have investigated and implemented alien plant biological control on a large scale, and is regarded as a leader in this field. South Africa was also prominent in the conceptualisation and execution of the international SCOPE project on the ecology of biological invasions in the 1980s, during which South African scientists established themselves as valuable contributors to the field. The development of invasion science benefitted from a deliberate strategy to promote multi-organisational, interdisciplinary research in the 1980s. Since 1995, the Working for Water programme has provided funding for research and a host of practical questions that required research solutions. Finally, the establishment of a national centre of excellence with a focus on biological invasions has made a considerable contribution to building human capacity in the field, resulting in advances in all aspects of invasion science—primarily in terms of biology and ecology, but also in history, sociology, economics and management. South Africa has punched well above its weight in developing the field of invasion science, possibly because of the remarkable biodiversity that provided a rich template on which to carry out research, and a small, well-connected research community that was encouraged to operate in a collaborative manner.https://link.springer.com/chapter/10.1007%2F978-3-030-32394-3_13Publisher’s versio

Investigating the risks of removing wild meat from global food systems

The COVID-19 pandemic has brought humanity’s strained relationship with nature into sharp focus, with calls for cessation of wild meat trade and consumption, to protect public health and biodiversity.1,2 However, the importance of wild meat for human nutrition, and its tele-couplings to other food production systems, mean that the complete removal of wild meat from diets and markets would represent a shock to global food systems.3, 4, 5, 6 The negative consequences of this shock deserve consideration in policy responses to COVID-19. We demonstrate that the sudden policy-induced loss of wild meat from food systems could have negative consequences for people and nature. Loss of wild meat from diets could lead to food insecurity, due to reduced protein and nutrition, and/or drive land-use change to replace lost nutrients with animal agriculture, which could increase biodiversity loss and emerging infectious disease risk. We estimate the magnitude of these consequences for 83 countries, and qualitatively explore how prohibitions might play out in 10 case study places. Results indicate that risks are greatest for food-insecure developing nations, where feasible, sustainable, and socially desirable wild meat alternatives are limited. Some developed nations would also face shocks, and while high-capacity food systems could more easily adapt, certain places and people would be disproportionately impacted. We urge decision-makers to consider potential unintended consequences of policy-induced shocks amidst COVID-19; and take holistic approach to wildlife trade interventions, which acknowledge the interconnectivity of global food systems and nature, and include safeguards for vulnerable people

Wild Meat Is Still on the Menu: Progress in Wild Meat Research, Policy, and Practice from 2002 to 2020

Several hundred species are hunted for wild meat in the tropics, supporting the diets, customs, and livelihoods of millions of people. However, unsustainable hunting is one of the most urgent threats to wildlife and ecosystems worldwide and has serious ramifications for people whose subsistence and income are tied to wild meat. Over the past 18 years, although research efforts have increased, scientific knowledge has largely not translated into action. One major barrier to progress has been insufficient monitoring and evaluation, meaning that the effectiveness of interventions cannot be ascertained. Emerging issues include the difficulty of designing regulatory frameworks that disentangle the different purposes of hunting, the large scale of urban consumption, and the implications of wild meat consumption for human health. To address these intractable challenges, we propose eight new recommendations for research and action for sustainable wild meat use, which would support the achievement of the United Nations Sustainable Development Goals
