Participatory Mapping with Herders in a Climate Adaptation Research Project.

Declining grazing lands threaten the livelihoods of Fulɓe herders in Burkina Faso and other parts of Africa. I used GIS to spatially represent ethnographic narratives about land use and land cover changes. In a place where maps were unavailable or treated as closely held community secrets, I used participatory mapping to offer participants the opportunity to control the process and resulting maps. Our project sought to understand environmental challenges from a fine-grained emic perspective using high-resolution satellite imagery and focus groups. I reflect on challenges of conducting fieldwork in one's home country, which made it easier to build relationships and interact with officials. At the same time, however, I faced the intersecting challenges of "being an outsider and a woman" as I interacted with Fulɓe men and that of being "too educated" in interacting with women.

Violent conflict exacerbated drought-related food insecurity between 2009 and 2019 in sub-Saharan Africa.

Conflict, drought and locusts are leading concerns for African food security but the relative importance and spatiotemporal scale of crises resulting from each hazard is poorly characterized. Here we use continuous, subnational data to demonstrate that the rise of food insecurity across sub-Saharan Africa that began in 2014 is attributable to an increase in violent conflict, particularly in South Sudan and Nigeria. Although drought remains a leading trigger of food crises, the prevalence of drought-related crises did not increase from 2009 to 2018. When exposed to drought, pastoralists experienced more widespread, severe and long-lasting food crises than people living in agricultural zones. Food insecurity remained elevated in pastoral regions for 2 years following a drought, while agricultural regions returned to pre-drought food-security levels in ~12 months. The few confirmed famines during the 2009-2018 period coincided with both conflict and drought, while locusts had little effect on food security during this period.

Participatory Mapping with High-resolution Satellite Imagery: A Mixed method Assessment of Land Degradation and Rehabilitation in Northern Burkina Faso.

Sahelian West Africa is a region that suffers from high population densities, frequent severe droughts, and enormous pressure on natural resources. Because of these challenges, it is the place where the term "desertification" was originally coined. Recently, however, experts have identified large zones of "greening" where the amount of vegetation exceeds what one would expect based on rainfall alone. This pattern is well documented, but its mechanisms remain poorly understood. This research employs participatory mapping linked with high-resolution satellite imagery to better understand the human role behind regional vegetation trends. Through a case study of three communities in northern Burkina Faso, this paper presents a pilot methodology for explicitly mapping perceived areas of both land degradation and rehabilitation. Combining participatory mapping exercises with standard image classification techniques allows areas of land degradation and rehabilitation to be precisely located and their extents measured for individual communities and their surrounding terroirs. Results of the spatial analysis show that the relative proportion of greening and browning varies among communities. In the case of Sakou, nearly 60 percent of its terroir is degraded. While in another, Kouka, this is 48 percent. This method also elicits perspectives of Burkinabè agro-pastoralists on the local land-use practices driving these twin environmental processes. Altogether, this case study demonstrates the analytical power of integrating ethnography and high-resolution satellite imagery to provide a bottom-up perspective on social-ecological dynamics.

'Where's the map?': Integrating ethnography with maps to understand the complementarity between pastoral mobility and border formation.

The resettlement of herders in pastoral zones is often criticized for hindering pastoral mobility, which is essential to survival. We integrate narratives of conflict and environmental change with maps to demonstrate the complementarity between pastoral mobility - porous borders- and border demarcation - rigid borders. We use evidence from the Sondré-Est Pastoral Zone in southern Burkina Faso, where herders were voluntarily resettled near agricultural villages following the droughts of the 1970s. Over time, however, farmers encroached on the borders of the pastoral zone and surrounding grazing areas declined. This increased land-use disputes. Tensions were exacerbated by the fact that these communities kept maps as community secrets. We re-created the administrative boundaries of the pastoral zone to map land-use/land-cover changes and conflict hot spots. The maps show that conflicts happened along porous borders where agricultural fields encroached. Herders called for a clear demarcation of the border of the pastoral zone to preserve exclusive access to resources within it. Simultaneously, they also wanted to maintain shared access to other resources outside the pastoral zone. The herders' desire for both border clarity and some form of flexibility underlines the complementary between both processes, especially in times of resource scarcity and land-use conflict. The mystery around the maps helps sustain ambiguity that is key for pursuing both goals.

La réinstallation des éleveurs dans les zones pastorales est souvent perçue comme étant une entrave à la mobilité pastorale, essentielle à la survie dans le Sahel. Nous associons les récits sur les conflits et changements environnementaux à des cartes pour démontrer la complémentarité entre la mobilité pastorale ­ nécessitant des frontières poreuses - et la démarcation des frontières ­ imposant des frontières rigides. Nous utilisons comme exemple la zone pastorale de Sondré-Est dans le sud du Burkina Faso, où les éleveurs ont été volontairement réinstallés près des villages agricoles à la suite des grandes sécheresses des années 1970. Au fil du temps, cependant, les agriculteurs ont empiété sur les frontières de la zone pastorale, diminuant ainsi les zones de pâturage environnantes. Cela a accru les conflits d'utilisation des terres entre éleveurs et agriculteurs. Les tensions sont exacerbées par le fait que les cartes montrant les limites réelles de la zone pastorale sont gardées comme des secrets communautaires. Nous avons recréé les limites administratives de la zone pastorale pour cartographier les changements d'utilisation des terres et de la couverture terrestre ainsi que les lieux principaux de conflits. Les cartes montrent que les principaux conflits se sont produits le long de frontières poreuses où les champs agricoles empiétaient. Une démarcation claire de la frontière de la zone pastorale pourrait préserver l'accès exclusif des éleveurs aux ressources en son sein. Cependant, le désir des éleveurs de clarifier les frontières et de maintenir simultanément une certaine forme de flexibilité pour l'accès aux ressources en dehors de la zone souligne la complémentarité entre les deux processus, à savoir la démarcation des frontières et la mobilité pastorale. Cette complémentarité est encore plus importante en période de pénurie de ressources et de conflits. Le mystère autour des cartes contribue à entretenir une ambiguïté qui est essentielle pour atteindre simultanément les deux objectifs.

Ground-truthing Sahelian Greening: Ethnographic and Spatial Evidence from Burkina Faso.

Historically, the Sahel of West Africa has been considered synonymous with desertification. In recent decades, however, satellite images reveal patterns of enhanced vegetation termed the "greening of the Sahel." This greening is well-documented but its mechanisms remain poorly understood. The Sahel is also a region emerging from a thirty-year period of reduced rainfall in which several severe droughts occurred. As a response to droughts and land degradation, farmers have rehabilitated thousands of hectares of degraded soils by constructing low barriers of rock through widespread soil and water conservation (SWC) development projects. Remote sensing analyses suggest that these extensive soil conservation projects may explain greening in northern Burkina Faso. This study combines ethnographic fieldwork with the analysis of Geographic Information System (GIS) and remote sensing (RS) data to test whether SWC investments contribute to greening. Ethnographic data reveals a tension between the perceptions of rural producers who feel that their SWC efforts contribute to greening and those of state officials who contend that SWC has only local impacts and that the regional landscape continues to degrade. Our analysis of GIS and RS data suggest that both perspectives are valid but contingent on particular spatial and temporal scale used for analysis.

Famines are a Thing of the Past: Food Security Trends in Northern Burkina Faso.

Sub-Saharan Africa is often portrayed as a region of chronic hunger, conflict, and poverty. The country of Burkina Faso is a bright spot on the continent where government agencies, NGOs, and development organizations have progressively improved food security to the point where citizens often state, "famines of the past could never happen again." This study evaluates such claims by looking at food security trends over the last 18 years using ethnographic participatory fieldwork and grain price data. Community members have invested in numerous soil and water conservation (SWC) measures that buffer their crops from droughts and agro-climatic variability. There is also a national famine early warning system in place and improved infrastructure that helps the government and NGOs efficiently provide food assistance in times of need. Thus, fewer households are affected when droughts occur due to these adaptations and food insecurity is not as severe or widespread as in the past. Local grain prices are, however, rising and becoming more closely linked to world food markets. Just as most households are becoming more food secure, those who are dependent on grain purchases are becoming more food insecure.
