Settlement in Transition: a Transformation of a Village into a Small Town in Western Sudan

UN-Habitat projects Sub-Saharan Africa’s global share of the urban population to increase from 11.3% in 2010 to 20.2% by 2050. Yet little is documented about the underlying urbanization processes, particularly of emergence of small towns. This article uses household interviews, focus groups, observation, and secondary data to examine the spontaneous transformation of a western Sudanese village, Shubbola, into a small town. We use changes in building construction approach, materials, and style as an indicator of development and provide rare documentation of the process, the main actors, choices taken, timescales, and outcomes of the rapid urbanization of Shubbola between 2006 and 2013. Housing transformation was variable but involved a gradual process of replacing traditional non-durable building materials (wood and straw) with modern durable ones (sun- or fire-cured bricks, cement blocks, and metal roofs). Unlike traditional top-down models of urbanization generally driven by government investment, Shubbola epitomizes an organic, bottom-up process dependent on self-reliance and agriculture development fueled by remittances from urban-based relatives. While many small towns with similar origins fail to do so, Shubbola already provided important urban services to its inhabitants and surrounding rural areas. The study enhances understanding of small towns and underlying urbanization processes and their contribution to often neglected bottom-up, low-cost processes that do not fit traditional top-down models. It also contributes to literature and policy on sustainable cities and their role in sustainable development as encapsulated in UN Sustainable Development Goal 11. The study contributes to understanding the processes and implications of rapid urbanization in the Sudan and Africa and other world regions

Persistent Barriers to Implementing Efficacious Mosquito Control Activities in the Continental United States: Insights from Vector Control Experts

Many barriers undermine vector surveillance and control efforts in the United States. Experts warn that such barriers, including funding, threaten the capacity of public-health surveillance systems to detect emerging mosquito-borne disease and respond appropriately, timely and effectively. This chapter explores the status, barriers, and corrective strategies to effective mosquito surveillance and control in the US based on experiences and insights of the 35 interviewed representatives of diverse mosquito-control programs selected from 18 U.S. states. Although our interest is in mosquito-borne diseases, we focus on the 2016 Zika outbreak. For the most part, this chapter will outline issues relating to mosquito control and surveillance that have persistent among state, county and municipal programs as a result of insufficient and unreliable funding, inadequate trained personnel, poor facilities, and inadequate political support. At the community level, we will discuss issues that hinder mosquito control efforts including apathy and low public awareness, and provide examples of how mosquito control agencies have adapted to “readily” respond to changing vector-borne disease environments, demands and constrained funding

Do youth conceptualizations influence the inclusion of young people in sustainable agriculture intensification? Insights from Ghana and Malawi

We examine local conceptualizations and definitions of the youth and how they influence youth inclusion in sustainable agriculture intensification (SAI) in Ghana and Malawi amidst challenges of high youth unemployment and underemployment, food insecurity, and rural out-migration. We use data from focus group discussions and key informant interviews. Definitions of youth(hood) varied among communities and agricultural officials based on age mediated by multiple socio-cultural, demographic, biological, economic, and relational factors. Conceptual mismatches between national formal and local definitions, and negative perceptions of youths undermined youth inclusion. Unpacking and harmonizing conceptualizations of youths as human capital and youth as transitional condition with local definitions that also foster positive youth identities and cultures, and treating dependent and independent youth separately, can reveal meaningful, youth-inclusive intervention points. It can enhance youth opportunity spaces and agency for their increased engagement in SAI, and help to avoid misguided policies arising from conceptual reductionism of youth

Sociospatial geographies of civil war in Sierra Leone and the new global diamond order: is the Kimberley process the panacea?

We examine the relationship between diamonds and conflict, and performance of the Kimberley Process Certification Scheme (KPCS) in combating ‘conflict diamonds’ using Sierra Leone as a case study and theory on the social production of scale. A ‘glocalization’ process produced lawless spaces and economic opportunities for rebels to circumvent national controls through subregional networks and to access global capital to fund conflict, while KPCS arrangements stemmed conflict diamonds by restoring state regulation and transparency. We contend that the KPCS and its scaling were initially more about protecting economic interests of major diamond companies and trading countries than about ‘ethical diamonds’. The KPCS externalized costs to national governments and poor alluvial-diamond-producing countries relative to industry players; hence the discordance between near elimination of conflict diamonds globally and relative failure in these countries. Findings suggest an approach differentiated by country circumstances, and broadening the KPCS from conflict to illicit and development diamonds.

Analyzing Geographical Access to HIV Sentinel Clinics in Relation to Other Health Clinics in Zambia

This paper illustrates that in countries such as Zambia where available sentinel clinic data lack patient use information while including location and clinic type, advanced geospatial modeling can be a good proxy for measuring access to health care facilities including HIV sentinel clinics. The analysis shows mapped patterns of potential accessibility to HIV sentinel clinics versus all other clinics, while taking into consideration the spatial distribution of the country's population. The results indicate that Zambia has developed a relatively impressive set of health facilities-so much so that 98% of the population is within 50 km of a health facility, a reasonable distance for a day's bike ride, and nearly three in four are within 20 km. However, when it comes to HIV sentinel or surveillance clinics, this target is far from being realized, with only 52% percent of the population being within 50 km of a sentinel clinic

Landscape-scale effects of farmers’ restoration decision making and investments in central Malawi: an agent-based modeling approach

Local farmers’ engagement and contributions are increasingly underscored in resources restoration policy. Yet, empirical context-situated understanding of the environmental impacts of farmer-led restoration remains scant. Using six Agent-based Modeling (ABM) simulations that integrate multi-type data, we explore the potential spatial-temporal aggregate patterns and outcomes of local restoration actions in Central Malawi. Findings uncover a 10-year positive trend and spatially explicit potential restoration extent and intensity, greenness, and land productivity, all varying by farmer’s participation level. Landscape regreening is modestly promising with fluctuating greenness levels and low, slightly incremental, then steady land-productivity levels. Findings also show appropriate incentives, restoration knowledge, and inspiring local leadership as propitious management options for boosting local restoration. Bundling these enabling management and policy options would maximize local restoration. Findings suggest empowering bottom-up restoration efforts for enhanced environmental impacts. We also demonstrate the potential of using ABM to offer insights for spatially targeted, evidence-based restoration policy implementation and monitoring

Smallholder farmers and forest landscape restoration in sub-Saharan Africa: evidence from Central Malawi

Malawi is a sub-Saharan African country at the forefront of the contemporary forest landscape restoration movement that places local smallholder farmers and resources users at the center of restoration actions. However, the manifestations of farmer-led bottom-up restoration efforts at individual and collective levels, and how they add up to landscape-scale restoration outcomes remain understudied. We analyze the nature of restoration efforts across interlocked forest and agricultural landscapes, estimate the extent of farmlands under restoration, and examine the contextual drivers and barriers of restoration. We use a mixed-methods approach combining a multivariate Tobit regression model and a Poisson model based on a 2019 household survey (N = 480 households), and qualitative insights from seven focus group discussions from Malawi's Dedza and Ntchisi Districts. The estimated mean total area of restored farmlands per household was 1.10 ( ± 0.76) and 1.07 ( ± 0.72) acres, representing, on average, about 54 % and 43 % of the total household landholdings in Dedza and Ntchisi, respectively. Results also indicate restoration diversification and intensification patterns whereby farmers generally combine two or more land-management practices based on complementarities in achieving specific livelihoods, food security, and ecological goals of restoration, and on compatibility regarding labor and other inputs demand. Land configuration mattered. Land plots that were spatially consolidated and tenure-secured were associated with higher restoration efforts. Also, women restoration efforts are limited by their inadequate access to productive inputs. Therefore, restoration policies should center on strategies that improve land-ownership security while minimizing fragmentation within landholdings and promote gender-responsive interventions. Drivers of collective resources restoration include strong local leadership; perceived tangible benefits for firewood, NTFPs, and timber resources; secure rights to collect firewood and free access to grazing areas; and perceived balanced among payoffs for energy needs, climate change adaptation, and ecological goals. These can inform restoration programs involving collective actions and their governance

Improving Representation of Decision Rules in LUCC-ABM: An Example with an Elicitation of Farmers’ Decision Making for Landscape Restoration in Central Malawi

Restoring interlocking forest-agricultural landscapes—forest-agricscapes—to sustainably supply ecosystem services for socio-ecological well-being is one of Malawi’s priorities. Engaging local farmers is crucial in implementing restoration schemes. While farmers’ land-use decisions shape land-use/cover and changes (LUCC) and ecological conditions, why and how they decide to embrace restoration activities is poorly understood and neglected in forest-agricscape restoration. We analyze the nature of farmers’ restoration decisions, both individually and collectively, in Central Malawi using a mixed-method analysis. We characterize, qualitatively and quantitatively, the underlying contextual rationales, motives, benefits, and incentives. Identified decision-making rules reflect diverse and nuanced goal frames of relative importance that are featured in various combinations. We categorize the decision-making rules as: problem-solving oriented, resource/material-constrained, benefits-oriented, incentive-based, peers/leaders-influenced, knowledge/skill-dependent, altruistic-oriented, rules/norms-constrained, economic capacity-dependent, awareness-dependent, and risk averse-oriented. We link them with the corresponding vegetation- and non-vegetation-based restoration practices to depict the overall decision-making processes. Findings advance the representation of farmers’ decision rules and behavioral responses in computational agent-based modeling (ABM), through the decomposition of empirical data. The approach used can inform other modeling works attempting to better capture social actors’ decision rules. Such LUCC-ABMs are valuable for exploring spatially explicit outcomes of restoration investments by modeling such decision-making processes and policy scenarios

A Survey of Program Capacity and Skills of Florida Mosquito Control Districts to Conduct Arbovirus Surveillance and Control

Effective and efficient surveillance systems are key for preventing arthropod-borne diseases. We examined the capacity of Florida mosquito control districts (both state-approved and open programs, n = 90; 48.9% response rate). Questions centered on budgets, staffing levels, equipment, vector control measures, and staff perceptions of own agency's capacity to implement routine surveillance and vector control activities. Bivariate analyses indicate that districts with relatively large budgets have advanced capacities regarding staffing levels, employee specialties, mosquito control equipment, conduct routine surveillance and vector control yet they serve only a small proportion of the population. Independent tax districts' average annual budgets were 9 times higher than Board of County Commissioners programs in fiscal year 2017-18. Most respondents indicated that staff is appropriately trained, and has timely access to information and needed equipment for mosquito surveillance and control. Slightly more than half of respondents feel they are understaffed. Perceived understaffing may compromise mosquito surveillance and control efforts in some districts
