    Colonial Zambia’s tsetse control efforts were deeply intertwined with wildlife management, shaping lasting ecological impacts.– Lacan, L. 2024

    The article examines the historical efforts to control the tsetse fly in colonial Zambia (1895–1959), providing a nuanced exploration of how these measures were deeply intertwined with the broader colonial project of reshaping the natural and social landscape. Tsetse control efforts were driven by the threat posed by the fly, a vector for trypanosomiasis (sleeping sickness) in both humans and livestock, which significantly hindered colonial agricultural and economic goals. Central to these efforts was the management of wildlife, which was viewed through a dual lens: as both a threat and a resource. On the one hand, wild animals were seen as reservoirs for the tsetse fly, perpetuating the disease cycle, leading to widespread campaigns of game elimination. On the other hand, wildlife was valued as a source of revenue through hunting and tourism, complicating the narrative around its eradication.

    To control tsetse populations, colonial authorities employed aggressive and often disruptive methods, including the mass culling of wildlife, clearing large tracts of vegetation to destroy the fly’s habitat, and forcibly resettling human populations to create “fly-free zones.” These interventions reflected the colonial vision of separating “civilized” human spaces from the untamed wilderness, reinforcing a dichotomy between humans and nature. This separation was not only physical but ideological, shaping policies that prioritized agricultural and economic development at the expense of ecological balance and local livelihoods. The article also explores the long-term consequences of these colonial policies on Zambia’s wildlife management and conservation efforts. Many of the practices and attitudes established during this period, such as the demarcation of conservation areas and the displacement of local communities, continue to influence contemporary conservation strategies. These legacies highlight the enduring tensions between conservation goals, economic development, and the rights of indigenous populations, offering critical insights into the intersection of environmental and colonial histories.

    How the Study was Conducted

    The study employed a combination of archival research and analysis of historical records. The author examined various methods used for tsetse control, such as game elimination, vegetation clearing, and resettlement of populations, and also analyzed the impact of these methods on wildlife management and conservation areas. The study involved reviewing documents, reports, and correspondence from the colonial period to understand the strategies and policies implemented for tsetse control and their long-term effects on the environment and local communities

    What the Authors Found

    The authors found that the tsetse control efforts in colonial Zambia were deeply intertwined with wildlife management. The author also discovered that wildlife was viewed both as a threat to be eliminated and as a resource to be conserved.

    Why is this important?

    This study is important because it sheds light on the historical practices of tsetse control and wildlife management in colonial Zambia, revealing how these efforts were deeply intertwined. The findings highlight the lasting impact of colonial policies on current wildlife management and conservation areas. Understanding this history helps us appreciate the complexities of managing human-wildlife interactions and the long-term consequences of past interventions on the environment and local communities.

  • Obstetric Violence in Sub-Saharan Africa: Addressing Maternal Care Abuse and Systemic Failures

    Obstetric Violence in Sub-Saharan Africa: Addressing Maternal Care Abuse and Systemic Failures

    In August 2013, Josephine Majani, a mother of three from Bungoma County in Kenya, endured an appalling birth experience. Despite her desperate cry for help during labor, hospital nurses ignored her plight. Struggling to walk to the labor ward amid excruciating pain, she discovered that all the beds were occupied. With no alternative, she was forced to give birth on the cold concrete floor.

    Majani’s ordeal did not end there. The attending nurses subjected her to verbal and physical abuse, even compelling her to carry her placenta back to the labor ward. Seeking justice for this traumatic experience, she turned to Kenya’s judiciary. In February 2024, Kenya’s Court of Appeal upheld an earlier High Court decision in her favor—a ruling that came six years after the initial judgment and eleven years after the incident.

    Her story sheds light on obstetric violence, a widespread but underreported form of abuse in maternal healthcare across Sub-Saharan Africa. This case underscores urgent systemic failures that allow such mistreatment to persist, raising critical questions about the state of maternal care in Kenya and beyond.

    The Silent Epidemic of Obstetric Violence

    Obstetric violence, as defined by the United Nations Special Rapporteur on Violence Against Women, encompasses verbal and physical abuse, neglect, non-consensual medical procedures, and unlawful detention for unpaid medical bills during childbirth. It is a gender-based violation of women’s rights to health, dignity, autonomy, and freedom from cruel, inhumane treatment.

    Despite its prevalence, obstetric violence remains underreported, earning it the label of a “silent epidemic.” Data on the issue is sparse even globally, limiting understanding of its true scope. Where data does exist, the findings are alarming. For instance, 20% of women in Kenya report mistreatment during childbirth—a figure mirrored in countries like Tanzania, Ghana, Nigeria, and Ethiopia. Given the lack of comprehensive statistics, the actual rates are likely higher.

    Addressing obstetric violence requires a multifaceted approach, including increased research funding to illuminate its prevalence and nuanced solutions tailored to specific countries.

    Abuse and Neglect Across the Region

    Kenya:
    Even with initiatives like Linda Mama, which offers free maternity services, Kenya’s public hospitals remain chronically underfunded, understaffed, and overwhelmed. Reports indicate that approximately one-third of adolescent mothers experience stigma or abuse from healthcare workers, with 10% suffering outright neglect during childbirth.

    Although Kenya’s Constitution guarantees the right to the highest attainable standard of health (Article 43(1)(a)) and the Maputo Protocol affirms women’s rights to dignity and health, implementation remains weak. Josephine Majani’s court victory, while a step forward, underscores the systemic obstacles women face when seeking justice.

    Uganda:
    In Uganda, one of the most egregious forms of obstetric violence is the detention of women post-delivery for failing to pay medical fees. This practice not only violates international human rights laws but also highlights the systemic inequalities in access to maternal care. With a maternal mortality rate of 375 deaths per 100,000 live births, women—especially in rural areas—face compounded risks from inadequate healthcare access.

    Despite ratifying international human rights instruments, Uganda struggles with enforcement, leaving countless women vulnerable to mistreatment.

    Nigeria:
    In Nigeria, chronic underfunding of the healthcare system exacerbates obstetric violence. In 2024, Nigeria allocated just 4.47% of its national budget to healthcare, falling far short of the 15% target set by the Abuja Declaration. High maternal mortality rates and widespread mistreatment during childbirth remain stark reminders of systemic inadequacies.

    While the African Commission on Human and Peoples’ Rights acknowledged the gravity of Nigeria’s maternal health crisis in a 2024 decision, aligning these efforts with international human rights standards remains a critical challenge.

    The Systemic Drivers of Obstetric Violence

    The persistence of obstetric violence is rooted in intersecting systemic issues:

    1. Weak Accountability Mechanisms:
      Healthcare systems often lack oversight structures to prevent and address mistreatment. This allows abuse to continue unchecked, particularly in resource-constrained settings.
    2. Societal Norms:
      Deeply entrenched gender inequalities marginalize vulnerable women, especially those from rural or impoverished backgrounds.
    3. Resource Deficits:
      Chronic underfunding of maternal healthcare leads to overwhelmed facilities, inadequate staffing, and insufficient training, creating environments where abuse thrives.

    Strategies for Addressing Obstetric Violence

    Combatting obstetric violence requires a multi-pronged approach:

    1. Strengthen Accountability:
      Ombudsman systems should be established in hospitals to provide women with transparent, impartial avenues for reporting mistreatment. This model, effective in countries like Malawi, could be adopted in Kenya, Uganda, and Nigeria.
    2. Legal Advocacy:

  • Digital Transformation of Welfare in Africa: Challenges, Opportunities, and Inclusive Solutions

    Digital Transformation of Welfare in Africa: Challenges, Opportunities, and Inclusive Solutions

    The digital transformation of welfare systems in Africa represents both a milestone in accessibility and a critical challenge for inclusivity. Welfare payments—government financial support provided to individuals who cannot work due to pregnancy, disability, illness, or old age—constitute an essential part of social protection. This framework is vital for upholding basic human rights, alleviating poverty, and ensuring societal dignity and health.

    Historically, social protection systems are funded through a mix of worker contributions and general taxation, creating a safety net for those in need. As of 2010, only five African nations—Ethiopia, Ghana, Malawi, Rwanda, and South Africa—had comprehensive social protection policies. By 2019, this number had grown to 35 out of 54 countries, showcasing the continent’s commitment to expanding these programs.

    The Digital Leap in Social Protection

    Recent years have seen a rapid shift toward digitalizing social protection systems. Digital platforms allow individuals to apply for and receive welfare payments online or via mobile phones. This shift offers numerous advantages: reduced travel to government offices, decreased waiting times, elimination of excessive paperwork, and the convenience of 24/7 access to services.

    However, the digital transformation also reveals significant inequalities. Millions of marginalized people face barriers that prevent them from benefiting from these advancements. The two largest obstacles are a lack of internet access and smartphones, compounded by inadequate digital literacy.

    The Digital Divide in Sub-Saharan Africa

    In sub-Saharan Africa, only about 51% of the population owns a smartphone, and less than one-third have internet access. These statistics highlight the inequities of digital transformation, particularly for vulnerable groups such as informal sector workers, people with disabilities, and rural communities. While digital systems streamline processes for some, they unintentionally exclude those most in need of social protection.

    Research Findings: Challenges in Digital Social Protection

    A 2023 study—the largest of its kind—investigated the impacts of digital social protection systems on marginalized workers across seven African nations: Ghana, Kenya, Nigeria, South Africa, Tanzania, Uganda, and Zambia. Conducted in partnership with labor, disability, and digital rights organizations, the research involved 276 surveys, 36 interviews with key informants, and 421 focus group participants.

    The study unveiled numerous barriers marginalized workers face:

    1. Availability: Many workers live in areas without reliable 4G networks or electricity, rendering digital systems inaccessible. These infrastructural gaps hinder registration and payment processes.
    2. Affordability: The high costs of smartphones and mobile data remain prohibitive. As a domestic worker from Zambia explained, “Most of us don’t have big phones with internet.”
    3. Awareness: Workers often lack awareness of their rights or knowledge of how to access digital systems. Campaigns to educate informal workers on these platforms are insufficient.
    4. Abilities: The lack of digital literacy, financial skills, and access to services in local languages limits participation. Online forms are predominantly in English, further excluding non-English speakers.
    5. Accessibility: Platforms often fail to accommodate disabilities. For instance, blind users lack adaptive technologies, and ATMs are not wheelchair-friendly.
    6. Accountability: Digital systems can diminish accountability and transparency. When errors occur, there is no human intermediary to assist, leaving workers frustrated and powerless. Additionally, concerns about data privacy and misuse of personal information were repeatedly raised.

    Structural Drivers of Digitalization

    The study highlighted that the shift to digital systems was largely driven by senior managers seeking efficiency gains and development donors like the World Bank, Mastercard, and private IT corporations. While proponents emphasize reduced corruption and cost savings, the top-down nature of these initiatives often excludes the voices of the very people they aim to serve. Marginalized workers, particularly those in the informal sector, are rarely consulted or involved in designing these systems.

    Addressing the Six “A”s of Social Protection Access

    The research findings stress the importance of addressing six critical dimensions to ensure equitable access to social protection systems:

    1. Availability: Expanding network and electricity infrastructure is essential for broader access.
    2. Affordability: Reducing the cost of smartphones and mobile data is necessary to bridge the economic divide.
    3. Awareness: Launching robust awareness campaigns to educate workers about their rights and system usage is crucial.
    4. Ability: Providing training in digital and financial literacy can empower marginalized groups.
    5. Accessibility: Designing platforms with inclusivity in mind—offering services in local languages and accommodating disabilities—is vital.
    6. Accountability: Ensuring mechanisms for error correction and data protection can build trust in the system.

    The Way Forward: Inclusivity and Participatory Design

    To prevent digital exclusion, governments must retain non-digital options for accessing social protection systems, such as in-person registration and cash payments. Furthermore, marginalized groups and their representatives must be actively involved in every stage of the design, implementation, and evaluation of digital systems. Collaborative governance ensures that the tools meet the diverse needs of all stakeholders and leave no one behind.

    In conclusion, while the digitalization of welfare systems in Africa holds promise for greater efficiency and convenience, it must prioritize equity and inclusivity. By addressing systemic barriers and involving marginalized communities, governments can ensure that technological advancements benefit everyone, not just the digitally privileged.
