“…The survey allowed the development of a database that includes the location of green spaces in the communes of Bamako and Sikasso, and the type of green space according to the vegetation cover based on the typology described by [62][63][64][65][66]. Figure 2 shows the methodological process.…”

Increasing land use and land cover change and climate change have considerable impacts on urban green spaces and their ecosystem services. These impacts result in a loss of urban green space and particularly weaken the climate resilience of urban populations. Landsat imagery data from 1990 to 2020 were used to track the spatio-temporal dynamics of urban sprawl and its influence on the loss of urban green space in Bamako and Sikasso in Mali. Furthermore, a survey of local stakeholders was conducted to capture the perceptions of the status of urban green space. The results of the land use/land cover analysis of the cities between 1990 and 2020 showed that most of the vegetation classes, mainly urban green spaces, have been converted into built-up and bare land in both cities during the last 30 years. In Bamako, built-up land has risen from 5421 hectares in 1990 to 13,350 hectares in 2020, and in Sikasso, from 929 hectares in 1990 to 2213 hectares in 2020. Respondents mentioned street trees as the prevalent type of urban green spaces in both cities (20% of the respondents in Bamako and 24% in Sikasso). In addition, the majority of respondents perceived urban green spaces in Sikasso as having a good status and in Bamako as having a good or moderate status. This study recommends improving the number and quality of urban green spaces, which are crucial for the provision of ecosystem services and for the resilience of cities against climate change.

“…This methodology is not adapted to the discrimination of the discontinuous built-up areas (peri-urban areas), which is necessary in our case. The analysis performed in this study, based on spatial morphology, with processing of satellite images, is usually applied to identify the zones within the urban-rural gradient [13,34,35,45]. However, the morphological criteria used may pose challenges in terms of measurability, as a function of the spatial resolution of the satellite images used (high, medium, or low).…”

The rapid population growth in sub-Saharan Africa requires regular monitoring of the spatial expansion of cities in order to facilitate efficient urban planning. In this study, we quantified the dynamics of urban and peri-urban areas in the city of Kisangani from 1987 to 2021, based on morphological criteria. Results demonstrate continuous urban and peri-urban growth, with respective average annual change rates of 8.2% and 7.6%. The urban core area expanded from 13.49 km2 to 100.49 km2, resulting from an alternating process of diffusion and coalescence. Peri-urbanization indexes developed to assess the trend of the decline in urban densities indicate a phase of urban densification over the period 1987–2010 succeeded by a decline in urban density over the period 2010–2021 that is characterized by a large expansion of the peri-urban area. However, despite this trend observed between 2010 and 2021, the decrease in urban density was not effective between 1987 and 2021 in Kisangani, as the fraction of peri-urban area observed in 1987 remains equivalent to that observed in 2021. This suggests a continuity of urban densification despite increasing peri-urbanization.

“…It is characterized by a rainy season (November to March), a dry season (May to September), and two transition months (April and October) [39]. With an average annual temperature of 20 • C (minimum of 8 • C and maximum of 32 • C), annual rainfall amounts to 1270 mm with extremes of 717 and 1770 mm [11].…”

“…Unfortunately, unemployment affects all social groups, regardless of their level of education [10]. In addition, the serious economic crisis observed since the 1990s and following the bankruptcy of the main mining company, Gécamines, coinciding with a period of spectacular demographic explosion [11], increase in urban poverty [12], and food dependency [13], prompted Lubumbashi's estimated six million inhabitants to engage in informal income-generating activities for survival [10,12]. These activities mainly concern urban agriculture, which mostly draw on the production and seasonal marketing of short-cycle vegetable crops.…”

Factors Influencing the Sustained Adoption of Innovative Techniques by Urban Farmers in Lubumbashi, Democratic Republic of Congo

et al. 2022

A package of innovations was disseminated in urban agriculture and created real opportunities for employment, income, and the supply of vegetables of high nutritional quality. However, ten years later, farmers are working for a daily income of less than United State Dollars 1.25, and critical exceedances of heavy metal content standards in crops are recorded. Survey data collected from 202 farmers were used to identify, via the Logit model, the factors influencing the sustained adoption of the of two contrasting innovations of the package. The results of the exploratory survey of 537 farmers showed that 2.42% owned a motor pump, while the in-depth survey revealed that 25.2% of the 202 respondents were using motor pumps at the time of the survey. A total of 74.8% watered with buckets and watering cans. The high cost of the motor pump makes it inaccessible to farmers. Some tried to circumvent this constraint, which led to group purchases. Integrated soil fertility management was used by 58.4% of respondents. In total, 41.6% applied only chemical fertilizers. However, Integrated soil fertility management has been hampered by farmers’ difficulties in accessing organic matter. The results of the Logit model revealed that no socio-demographic factors were significant for sustained adoption of the motor pump. They were relevant, rather, for integrated soil fertility management, where a single factor (mutual aid) appeared to play a role, albeit a moderate one. Economic factors such as land tenure status and diversification of income sources were significant for a sustained adoption of the motor pump. In contrast, no economic factors were significant for a sustained adoption of the integrated soil fertility management. Institutional factors such as access to credit and membership in an association were significant for sustained adoption of the two of innovations studied. A series of avenues to follow to improve the productivity of farms is proposed. We suggest an in-depth study of the mutual aid practiced by 86.1% of the farmers. The results of this study can be taken into account in research and policy aimed at improving adoption of innovative techniques that are beneficial to farmers in developing countries.
