In the Sahel, host communities are among those most affected by recurrent internal displacement, but they are often ignored in responses to displacement. Furthermore, their situation has attracted little attention from researchers or other observers. The present article will argue that it is essential to provide these communities with adequate protection, especially as they play a leading role in providing humanitarian protection and assistance to internally displaced persons (IDPs). The article begins by examining the legal instruments that protect populations affected by forced displacement, in order to identify and present the legal protection they offer to IDP host communities. The article will then analyze and highlight the advantages of fully applying this protection. It will show that the recurrent violence and breaches of the law that these communities suffer are impeding the full realization of those advantages. Finally, the article shall propose solutions that would overcome the deficiencies noted and hence ensure enhanced protection for IDP host communities in Burkina Faso, Mali and Niger.

Parasites directly and indirectly influence the important interactions among hosts such as competition and predation through modifications of behaviour, reproduction and survival. Such impacts can affect local biodiversity, relative abundance of host species and structuring of communities and ecosystems. Despite having a firm theoretical basis for the potential effects of parasites on ecosystems, there is a scarcity of experimental data to validate these hypotheses, making our inferences about this topic more circumstantial. To quantitatively test parasites' role in structuring host communities, we set up a controlled, multigenerational mesocosm experiment involving four sympatric freshwater crustacean species that share up to four parasite species. Mesocosms were assigned to either of two different treatments, low or high parasite exposure. We found that the trematode Maritrema poulini differentially influenced the population dynamics of these hosts. For example, survival and recruitment of the amphipod Paracalliope fluviatilis were dramatically reduced compared to other host species, suggesting that parasites may affect their long-term persistence in the community. Relative abundances of crustacean species were influenced by parasites, demonstrating their role in host community structure. As parasites are ubiquitous across all communities and ecosystems, we suggest that the asymmetrical effects we observed are likely widespread structuring forces.

Before the Syrian civil war, Egyptians were the single largest migrant labor community in Jordan. Labor market pressures and changes to the Jordanian work permit system have resulted in the increasing vulnerability of Egyptian labor, who have been the primary labor force on Jordanian farms and construction sites since the late 1970s. Using new data from the 2015 Jordanian census, the 2010 and 2016 Jordan Labor Market Panel Survey, and field interviews conducted in Jordan from 2014 to 2018, I show that higher concentrations of Syrians at the subdistrict level are associated with higher rates of informal labor market participation for Egyptians. Furthermore, higher proportions of Syrians do not correlate with negative impacts on the formality or household wealth of Jordanian citizens, suggesting that Syrian labor does not directly compete with the Jordanian labor force. Given the importance of supporting host communities during refugee crises, this analysis sheds light on how mass forced migration affects other vulnerable segments of the migrant labor force in the Global South.

Community-based conservation efforts are designed to foster local stewardship of important ecological resources. However, inequitable distribution of costs and benefits in communities surrounding protected areas can negatively impact livelihoods, increase wealth disparities and create conflict. To examine the potential for conflict between host communities involved in a community-based conservation program and neighbouring (non-host) communities, we explored local residents’ attitudes towards conservation at Tiwai Island Wildlife Sanctuary (TIWS) in Sierra Leone. Intercept surveys (n = 368) were conducted in 18 villages (eight host, ten non-host) within 8 km of TIWS during 2010. Results revealed significant differences between residents of the host and non-host villages with respect to attitudes towards resource use and overall support for site protection. The most substantial discrepancies centred on perceived benefits associated with TIWS, and these drastically different perspectives generated a high potential for conflict. To minimize conflict and foster broader community support for conservation, managers must carefully consider how benefits associated with protected areas are communicated and distributed across protected area-proximate landscapes.
