The socio-economic drivers of bushmeat consumption during the West African Ebola crisis.

Bushmeat represents an important source of animal protein for humans in tropical Africa. Unsustainable bushmeat hunting is a major threat to wildlife and its consumption is associated with an increased risk of acquiring zoonotic diseases, such as Ebola virus disease (EVD). During the recent EVD outbreak in West Africa, it is likely that human dietary behavior and local attitudes toward bushmeat consumption changed in response to the crisis, and that the rate of change depended on prevailing socio-economic conditions, including wealth and education. In this study, we therefore investigated the effects of income, education, and literacy on changes in bushmeat consumption during the crisis, as well as complementary changes in daily meal frequency, food diversity and bushmeat preference. More specifically, we tested whether wealthier households with more educated household heads decreased their consumption of bushmeat during the EVD crisis, and whether their daily meal frequency and food diversity remained constant. We used Generalized Linear Mixed Models to analyze interview data from two nationwide household surveys across Liberia. We found an overall decrease in bushmeat consumption during the crisis across all income levels. However, the rate of bushmeat consumption in high-income households decreased less than in low-income households. Daily meal frequency decreased during the crisis, and the diversity of food items and preferences for bushmeat species remained constant. Our multidisciplinary approach to study the impact of EVD can be applied to assess how other disasters affect social-ecological systems and improve our understanding and the management of future crises.

Democracy and cooperation in commons management: experimental evidence of representative and direct democracy from community forests in Ethiopia

Abstract The authors use dynamic lab-in-the-field common pool resource experiments to investigate the role of two forms of democracy on the cooperation of forest users in Ethiopia. In this experimental setup, participants can either directly select a rule (direct democracy) or elect a leader who decides on the introduction of rules (representative democracy). These two treatments are compared with the imposition of rules and imposition of leaders. It is found that both endogenous leaders elected by the community members and endogenous rules selected by the direct involvement of the participants are more effective in promoting cooperation among the community members compared to exogenous leadership, exogenous rule imposition and the baseline scenario without any of these modifications. However, no significant difference is found between representative democracy in the election of leadership and direct democracy in the selection of rules. Leadership characteristics and behavior are further analyzed. The results underline the importance of democratic procedures.

Forest dependence and income inequality in rural Ethiopia: evidence from Chilimo-Gaji community forest users

The aim of the study was to examine the determinants of forest dependence and the role of community forest on income inequality in rural Ethiopia. Regression results, using Heckman’s two-stage estimation method, suggest that the probability of households’ participation in low-return forest activities is determined by farm size, number of male members in the household and distance from the forest plot to the household’s homestead. Further, the likelihood of households’ participation in high-return forest activities is determined by the number of male household members, the distance from the households’ homestead to the community forest block and being a member of the forest user group’s executive committee. Using instrumental variable method, we found that, in relative terms, households with more non-forest income are less likely to depend on forest commons for their livelihood. Further, wealthier households are less dependent on forest products for their livelihood. We also found that forest products play a crucial role in reducing income inequality in the study area. Income inequality increases by 24% when we exclude forest income from the calculation of inequality measure (Gini coefficient).

The impact of the Ebola virus disease (EVD) epidemic on agricultural production and livelihoods in Liberia.

There is unequivocal evidence in the literature that epidemics adversely affect the livelihoods of individuals, households and communities. However, evidence in the literature is dominated by the socioeconomic impacts of HIV/AIDS and malaria, while evidence on the impact of the Ebola virus disease (EVD) on households’ livelihoods remains fragmented and scant. Our study investigates the effect of the EVD epidemic on the livelihoods of Liberian households using the Sustainable Livelihood Framework (SLF). The study also explores the effect of the EVD epidemic on agricultural production and productive efficiency of farm households using Spatial Stochastic Frontier Analysis (SSFA). We collected data from 623 households across Liberia in 2015, using a systematic random sampling design. Our results indicated that the annual income of sample households from communities where EVD occurred did not differ from the annual income of households from communities where EVD did not occur. Nonetheless, the majority of sample households reported a decrease in their income, compared to their income in the year before the survey. This suggests that the impact of the EVD epidemic might not only have been limited to communities directly affected by the epidemic, but also it may have indirectly affected communities in areas where EVD was not reported. We also found that the community-level incidence of EVD negatively affected crop production of farm households, which may have exacerbated the problem of food insecurity throughout the country. Moreover, we found that the EVD epidemic weakened the society’s trust in Liberian institutions. In a nutshell, our results highlight that epidemics, such as the recent EVD outbreak, may have long-lasting negative effects on the livelihoods of a society and their effect may extend beyond the communities directly affected by the epidemics. This means that the nation’s recovery from the impact of the epidemic would be more challenging, and the social and economic impacts of the epidemic may extend well beyond the end of the health crisis.

Households’ dependence on community forest and their contribution to participatory forest management: evidence from rural Ethiopia

In recent decades, there has been a major shift in natural resource conservation policies in developing countries, and community-based natural resource management has become the integral part of the policies. Nonetheless, the link between the local communities’ dependence on forest resources for their livelihood and the likelihood of the success of community forest management has been understudied. Thus, this study investigates how forest dependence influences the contribution of local communities to the management of community forest, using the data collected from 190 households participating in community forest management in rural Ethiopia. It was found that the sample households derived almost 38% of their annual income from community forest. Moreover, results from mixed effects linear regression models show that forest dependence promotes contribution to collective action in the management of community forest. When households derive more income from the community forest relative to their total income, they contribute more to the management of the community forest. This suggests that the more the households depend on the community forest for their livelihood, the more they value the resource and the more they participate in the management of the forest. Thus, the results underline that the success of local communities in managing community forest may be significantly influenced by their level of dependence on the resources from the forest.
