“…In the sites in Diourbel-Louga, Senegal, Centre-Centre Sud in Burkina Faso, and Niger State in Nigeria, with very high livestock density (see Table 2), the BLR model predicted a negative impact of livestock density, especially cattle, on the presence of natural vegetation (see Tables 3 and 5 and Figure 6(b1,b2) for graphical representations of the cases in Diourbel-Louga, Senegal and Niger State, Nigeria). In reality, grazing and trampling pressure by livestock have negative impacts on total above ground biomass with pressure, increasing when livestock density increases [58,[86][87][88]. This is consistent with the findings from this study.…”

“…According to Schlecht et al [88], in highly populated and urbanized areas, livestock farmers dispose livestock dung in open spaces and streets. The exposure of dung to extreme sunlight and rainfall has negative implications on the environment since the process may lead to leaching of nutrients and emission of greenhouse gases, such as methane to the atmosphere with a subsequent impact on climate.…”

“…The exposure of dung to extreme sunlight and rainfall has negative implications on the environment since the process may lead to leaching of nutrients and emission of greenhouse gases, such as methane to the atmosphere with a subsequent impact on climate. In Burkina Faso, roadside grasses, fallowed vegetation and stubble material from public spaces within and particularly around the city, are contributing a significant share of dry matter intake of ruminants in Ouagadougou, which is one of the urbanized areas in the study site in Centre-Centre Sud of Burkina Faso [88].…”

Modeling the Underlying Drivers of Natural Vegetation Occurrence in West Africa with Binary Logistic Regression Method

et al. 2021

The occurrence of natural vegetation at a given time is determined by interplay of multiple drivers. The effects of several drivers, e.g., geomorphology, topography, climate variability, accessibility, demographic indicators, and changes in human activities on the occurrence of natural vegetation in the severe drought periods and, prior to the year 2000, have been analyzed in West Africa. A binary logistic regression (BLR) model was developed to better understand whether the variability in these drivers over the past years was statistically significant in explaining the occurrence of natural vegetation in the year 2000. Our results showed that multiple drivers explained the occurrence of natural vegetation in West Africa at p < 0.05. The dominant drivers, however, were site-specific. Overall, human influence indicators were the dominant drivers in explaining the occurrence of natural vegetation in the selected hotspots. Human appropriation of net primary productivity (HANPP), which is an indicator of human socio-economic activities, explained the decreased likelihood of natural vegetation occurrence at all the study sites. However, the impacts of the remaining significant drivers on natural vegetation were either positive (increased the probability of occurrence) or negative (decreased the probability of occurrence), depending on the unique environmental and socio-economic conditions of the areas under consideration. The study highlights the significant role human activities play in altering the normal functioning of the ecosystem by means of a statistical model. The research contributes to a better understanding of the relationships and the interactions between multiple drivers and the response of natural vegetation in West Africa. The results are likely to be useful for planning climate change adaptation and sustainable development programs in West Africa.

“…This will increase the demand for food and in particular livestock products [49], given that the per capita meat consumption of urban dwellers is also increasing as the middle class grows in Sub- The populations of cattle, sheep, and goats in Bamako have been estimated at 35,000, 58,000, and 36,000, respectively [35], which corresponds to a population of 33,900 ruminants of 250 kg body weight (Tropical Livestock Unit, TLU). With a yearly feed intake of 482 kg DM (dry matter) for an average sheep, 396 kg DM for a goat and 2156 kg for a cattle [46], it can be assumed that about 66,920 t of feed DM are required annually for the ruminant livestock herd in Bamako. Currently, the city loses surrounding grassland at a rate of about 2.6% per year while its urban area is expanding at 5.4% [47], mainly towards the Kabala axis, which is also one of the biggest zones of fodder production (Figure 6).…”

“…Currently, the city loses surrounding grassland at a rate of about 2.6% per year while its urban area is expanding at 5.4% [47], mainly towards the Kabala axis, which is also one of the biggest zones of fodder production (Figure 6). Where grassland is not converted into an urban built-up area, the transport of feeds into the city will lead to nutrient depletion of the feed-supplying rural hinterlands if the nutrients are not returned in the form of livestock manure [46].…”

Vehicular Livestock Mobility in West Africa: Seasonal Traffic Flows of Cattle, Sheep, and Goats across Bamako

Mali is a major livestock producing country in West Africa. However, in recent years, the sector has faced multiple challenges like farmer-herder conflicts, overuse of grazing and water resources, and the effects of climate change. Meanwhile, traditional livestock systems are becoming less important given the increased availability of vehicular transport for regional and international animal trade as well as new opportunities for more specialised urban and peri-urban production systems. To assess the role of Mali’s capital city Bamako for livestock consumption and trade, this study examined the scale of livestock movement in the city, comprising influxes, outfluxes, and transits. To this end, flows of cattle, small ruminants, and livestock feed were recorded through road surveys covering three different seasons. The results showed the role of Bamako as a major trade hub in the distribution of ruminants. While traffic of cattle and sheep was regional, movement of goats was smaller and more localised. Religious festivals were an important driver of livestock traffic, both in terms of the numbers of livestock and the distance covered. This study highlights the role of cities for livestock mobility and contributes to a better understanding of challenges related to urban livestock production and trade and its requirements for better livestock management.

The global challenge of rural-urban transformationDuring the last two decades the benefits, risks, negative externalities, and future social-ecological challenges of urban and (peri-) urban agriculture (UPA) have received increasing attention (Lydecker and Drechsel 2010;Safi and Buerkert 2011;Drechsel and Keraita 2014;Thebo et al. 2014). A main cause for this attention is the growing awareness of rapid ruralurban transformation processes that are changing matter flows, resource allocation, and ecosystem functioning as a consequence of strong shifts in the distribution of people along the rural-urban gradient (Cumming et al. 2014;Angel et al. 2005). It has been estimated that by 2050 the share of the global urban population may reach 68% compared with 55% today (United Nations 2017). Given continuing population growth, this phenomenon, in absolute numbers, entails
