Design and management considerations for the Kenya-Tanzania marine transboundary conservation area.

Although transboundary conservation areas (TCAs) are critical tools for protecting ecosystems and ecological processes that transcend national jurisdictions, they are challenging to create due to the differences in governance contexts and capacity and power dynamics among countries. Marine TCAs are also more difficult to enforce relative to terrestrial TCAs because most nations still treat oceans as open access. Current guidelines for TCA development and implementation also focus mostly on terrestrial TCAs, which are not practical for marine TCAs. Hence, we reviewed the challenges associated with the design and management of marine TCAs and devised analytical and practical approaches to support the application of spatial planning frameworks and adaptive governance mechanisms. We used the lessons from the review to examine the decisions made for the proposed marine TCA in the Kenya-Tanzania border region and created options and considerations to promote effective design and management processes. We found the obstacles to marine TCAs in general are related to issues of fit, particularly differences in environmental research capacity, socioeconomic contexts, and internal institutional arrangements. These included differences in knowledge and capacity for marine ecological research and conservation; ability to adjust and update data; differences in values, interests, and resource uses; conservation costs; jurisdictional differences; engagement of multiple levels of organization; and differences in legal bases and policy development processes. Understanding and reconciling these challenges during the TCA development process can help enhance meaningful discussions in the design of the TCA and cultivate the enabling conditions for collaborative governance across countries and within different levels of organization from national to local actors.

Fostering international and trans-boundary cooperation in the management of Lake Chad fisheries, wildlife and flora: the role of a trans-boundary Ramsar conservation area

The Lake Chad basin is one of the most politico-ecologically complex regions in Africa. The rapid global climate change caused by decades of unsustainable resource utilization has not only impaired the ecosystem function but has escalated further conflict with the associated terrorism in the region. This paper reviews the notion of environmental peacebuilding through the introduction of trans-boundary conservation as a mechanism to achieve peace and harmony in the Lake Chad region. The proposed trans-boundary conservation area will restore ecosystem services, conserve biodiversity, improve livelihood, and reduce poverty in the Lake Chad basin. The paper provides justification for the establishment of the “Lake Chad trans-boundary Ramsar site” as an example of how a trans-boundary conservation area could act as a catalyst for improved political cooperation using inter-linkage with other Multilateral Environmental Agreements in the region.

THE PERVERSE EFFECTS OF SHARED MANAGEMENT OF A CROSS-BORDER CONSERVATION AREA

Cross-border cooperation is gaining momentum across Africa, giving rise to a new type of natural resource management: shared management. The importance of this type of cooperation lies in the pooling of conservation efforts. The idea of this article is to contribute to this debate by analysing the functioning of transboundary governance in the field of natural resources within a transboundary conservation area (CTA) by providing an overview of the challenges caused by the institutionalisation of transboundary cooperation in the transboundary space. It is a question of taking into account the pernicious consequences of the cross-border project on symbolic representations, but also at the level of the cross-border institutional frameworks put in place. To provide an overview of these perverse effects and their nature, the methodology used is based on the analysis of perceptions and the study of the actors' interactions. The issue of shared management in a transboundary context is addressed through seven comparative case studies: W Park, Mount Nimba, Ziama-Wonogizi-Wologizi, Outamba Kilili Pensely Soya, Télé-Lac Tumba, Tri National de la Sangha and Virunga.

Quality of Environmental Impact Assessment Reports for Lodge Developments in Protected Areas: The Okavango Delta Case, Botswana

This paper evaluates the quality of environmental impact assessment (EIA) reports for lodge developments in Botswana’s Okavango Delta, which is a wetland of international importance and forms part of a transboundary conservation area and world heritage site. A quality review of 31 EIA reports, approved between 2013 and 2021, was conducted by applying a context specific EIA report quality review package. The review package consists of four review areas with seventeen categories and 64 sub-categories, adapted from similar international packages to address the specific legal requirements for EIA in Botswana as well as best practice. Results show that the overall quality of the reports are poor, with 71% graded as ‘unsatisfactory’. In general, descriptive areas of the EIA reports fared better, while the performance of the more analytical areas was ‘poor’. Key areas of weakness include - the identification of impacts; prediction and assessment of impact magnitude; as well as identifying alternatives and mitigation measures. Overall results suggest that currently EIA report content is insufficient to inform decision-making towards sustainable tourism development in the Okavango Delta. It is recommended that areas of weakness can be addressed by providing clear strategic direction; developing a central data management system; setting norms and standards for tourism development as well as building capacity and awareness of key stakeholders. This will ensure that EIA remains a tool of choice for decision making and avoid becoming a mere ‘red-tape’/administrative process aimed at securing development approvals.

Identifying opportunities for transboundary conservation in Africa

The conservation of natural and cultural resources shared between countries is a significant challenge that can be addressed through the establishment of transboundary conservation areas (TBCAs). TBCAs enable countries to harmonize cross-border governance and management, increase protected area (PA) coverage, and strengthen relationships between neighbouring countries and communities. In Africa, many ecosystems and species ranges span multiple countries, making TBCAs a crucial tool for biodiversity conservation. However, there is a lack of research on where TBCAs can be established or need to be established. To address this gap, we conducted a study to identify opportunities for establishing TBCAs in Africa. We first compiled an up-to-date list of existing TBCAs on the continent. Then, we identified potential TBCAs by identifying protected areas next to country borders that are adjacent to other protected areas in a neighbouring country. We also evaluated the functional connectivity between these PA pairs and prioritized potential TBCAs based on size, connectivity, and ease of establishment. We identified 27 existing TBCAs and 8,481 potential TBCAs in Africa composed of various possible combinations of 2,326 individual PAs. Our results provide a baseline of existing TBCAs and offer a better understanding of where transboundary conservation might be established or strengthened. We also highlight areas where future transboundary conservation efforts could safeguard PA connectivity. This information can guide policy and decision-making processes towards promoting conservation and sustainable use of natural and cultural resources shared between countries in Africa.

Population estimate and conservation status of the Persian Leopard, Panthera pardus tulliana, in the Bamo and Khoshk Mountains in Kurdistan Region, northern Iraq

In Iraq, the endangered Persian Leopard (Panthera pardus tulliana) is distributed in the northern part (Kurdistan Region) along the Zagros mountain steppe ecoregion, which includes the Bamo and Khoshk Mountains, where we carried out a field survey between October 2020 and November 2022 including camera trapping and interviews with local communities. At least five individuals were recorded during this study, including males, a female, and a family, given a population density of 1.25 indivuduals/100 km2. Bezoar Goat and Wild Boar are their key prey species in the area. Poaching and wildlife trafficking, decreasing natural water sources, overgrazing, minefields, and forest fires are identified as key threats facing the Persian Leopard population, their prey species, and their natural habitats in the Bamo and Khoshk Mountains. It is suggested to designate the study area as a national protected area or a transboundary conservation area between Iraq and Iran.

Can Environmental Injustices be Addressed in Conservation? Settlement History and Conservation-Induced Displacement in the Case of Lyanshulu in the Zambezi Region, Namibia

The Zambezi Region of Namibia is known for its vast conservation landscape, which is part of the world’s largest transboundary conservation area – the Kavango Zambezi Transfrontier Conservation Area (KAZA TFCA). Less known are the settlement histories of the communities displaced from their villages during the planning and implementation of this conservation landscape. We reconstruct the settlement history of two families that lived on two islands in the Kwando River and the adjacent riverbanks in today’s Mudumu NP, and we describe the circumstances that led to the designation of a national park in this region and the subsequent conservation-induced displacement. The evicted families increasingly protest and legally contest estrangement from their ancestral land, which is now a protected area. We argue that current nature-conservation efforts can succeed only if issues of past and present environmental injustices are comprehensively addressed.

Historical and current distribution and movement patterns of large herbivores in the Limpopo National Park, Mozambique

This study provides a first attempt to describe the historical distribution and movement patterns of selected large herbivore (LH) species in Limpopo National Park (LNP), an area in Mozambique today connected to a network of transboundary conservation areas. Between 1976 and the early 2000s, most LH species were absent in this area following the civil war in Mozambique followed by intense poaching due to weak law enforcement capacity. Through the reconstruction of the historical and current distribution and movement patterns of seven LH species in five periods, we investigate possible changes in distribution and movement patterns over time. Data collection is based on a systematic literature search, censuses reports, online databases, dung count transects, and camera trap surveys. We mapped all LH observations and movements using ArcGIS 10.1. Our results reveal a dramatic collapse of LH populations between the peak of the colonial period and the post-colonial/civil war period (1800–2001), followed by a slight recovery from the post-proclamation of Great Limpopo Transfrontier Park to the current period (2002–2021). While LH population decline applied to all seven species, there are species-specific differences in the process of restoration: African elephant (Loxodonta africana), African buffalo (Syncerus caffer), and plains zebra (Equus quagga) appear to recover to a greater extent than giraffe (Giraffa camelopardalis), eland (Tragelaphus oryx), blue wildebeest (Connochaetes taurinus), and white rhino (Ceratotherium simum). We found evidence of the functioning of proposed wildlife corridors in the LNP. The results give reason to assume that restoration of populations of LH is still in a very early and vulnerable state and that further efforts are necessary to strengthen the slowly increasing populations of LH. Our results highlight the importance of combining past and current data as a guide for the restoration of threatened species in African savannas impacted by human activities.

Assessing Distribution Patterns and the Relative Abundance of Reintroduced Large Herbivores in the Limpopo National Park, Mozambique

This study is the first systematic assessment of large herbivore (LH) communities in Limpopo National Park (LNP) in Mozambique, an area where most LH species were extinct until the early 2000s. We investigate whether LH community parameters are linked with the availability of habitat types or the distance between sampling sites and the origin of LH resettlement. We placed camera traps in five habitat types in resettled and not-resettled areas to compare species richness, relative abundance index, grazers–browsers–mixed feeder and naïve occupancy of 15 LH species. While the richness decreased along the distance gradient of LH resettlement, relative abundance index strongly responded to habitat features. The grazer–browser–mixed feeder ratio oscillated, while from resettled to not-resettled areas, the ratio increased. Most species show a wide distribution range. The associations of most LH community parameters with habitat types rather than distance to initial release, together with the species-specific and guild-specific response patterns of LH, suggest LNP to already be in an intermediate stage of restoration. Our results highlight the importance of post-release monitoring of reintroduced wildlife as a tool to assess the success of ecological restoration initiatives in transboundary conservation areas.

Vulnerability of a top marine predator in one of the world’s most impacted marine environments (Arabian Gulf)

Knowledge of the habitat use of wildlife in highly impacted areas is essential to identify areas of biological importance and to implement appropriate conservation measures. The Arabian Gulf represents one of the most extreme marine environments and is considered one of the regions in the world with the greatest anthropogenic impact. Information on the habitat use and abundance of marine top predator species is, however, lacking, despite being a prerequisite for effective planning of conservation measures. Here, we provide novel information for the Indo-Pacific bottlenose dolphin (Tursiops aduncus) in the Arabian Gulf (Abu Dhabi, United Arab Emirates). Data from 80 daily surveys conducted between June 2014 and November 2019 were used both to assess correlates of bottlenose dolphin habitat use and relative density and to calculate mark-recapture abundance estimates. This study confirms the strong adaptability and tolerance of this top marine predator to extreme environmental conditions within a highly heterogeneous and impacted marine habitat. The observed preferences for areas with less human pressure were likely a result of the interactions of environmental factors with prey availability and human disturbance. This study also provides the first abundance estimates for a bottlenose dolphin population in the Arabian Gulf. Our findings support the call for increased marine-protected areas and the creation of transboundary conservation areas in the region. Regional connectivity should be of value to marine predators whose wide distribution and vulnerability to human activities means that alteration of their habitats can result in population declines and eventual local or regional extinctions.

Bound within boundaries: Do protected areas cover movement corridors of their most mobile, protected species?

Abstract Conserving and managing large portions of land to connect wildlife reserves is an increasingly used strategy to maintain and restore connectivity among wildlife populations. Boundaries of such conservation areas are often determined based on expert opinion and socio‐political constraints, yet the extent to which they match species' movement corridors is rarely examined. This is mainly due to a lack of data, particularly on wide‐ranging movement behaviour such as dispersal. Nevertheless, empirically assessing the adequacy of protected areas is key for the implementation of targeted management actions and efficient use of limited conservation funds. Between 2011 and 2019, we collected high‐resolution GPS data on 16 dispersing African wild dog Lycaon pictus coalitions from a free‐ranging population in the Kavango–Zambezi Transfrontier Conservation Area (KAZA‐TFCA). Spanning five countries and 520,000 km2, the KAZA‐TFCA is the world's largest transboundary conservation area and a prime example for international conservation efforts. We used integrated step selection analysis to estimate habitat selection of dispersers and to create a permeability surface for the KAZA‐TFCA. We compared landscape permeability across different regions within the KAZA‐TFCA as well as outside its boundaries. Lastly, we calculated least‐cost paths and corridors to verify that major movement routes were adequately encompassed within the KAZA‐TFCA. Permeability within the boundaries of the KAZA‐TFCA was more than double compared to areas outside it. Furthermore, we observed a fivefold permeability difference among the five KAZA‐TFCA countries. We also showed that major movement corridors of wild dogs ran within the KAZA‐TFCA, although some minor routes remained formally unprotected. Differences in permeability were mainly related to different degrees of human activities across regions, and to the presence or absence of rivers, swamps and open water. The relationship between permeability and other landscape features was less pronounced. Synthesis and applications. In this study, we showed how pertinent dispersal data of a highly mobile species can be used to empirically evaluate the adequacy of already existing or planned protected areas. Furthermore, we observed regional differences in landscape permeability that highlight the need for a coordinated effort towards maintaining or restoring connectivity, especially where transboundary dispersal occurs.

An indicator framework for assessing cooperative cross-border conservation in the Karakoram-Himalayan region

The Karakoram-Himalayan (KH) region comprises high mountains across seven countries (i.e., China, Afghanistan, Pakistan, India, Nepal, Bhutan, and Myanmar) with a variety of management regimes and priorities and capacities for conservation. Currently, there is no comprehensive framework for assessing cooperation on protected areas (PAs) in the KH region. Such a framework is essential to guide managers and policymakers in the formulation of consistent management plans and strategies for regional sustainable development. In this study, an indicator framework for assessing cooperation on PAs was developed based on four factors: the natural environment, the human environment, transport accessibility, and the diplomatic environment. The assessment involved 49 cross-border national parks and nature reserves in this region. Furthermore, the indicators were analyzed by using the analytic hierarchy process, resulting in eight cross-border groups. The analysis reveals that the region has a good foundation for cooperative cross-border conservation in general. Among the eight groups, the Karakoram-Pamir, Kangchenjunga, and Everest groups exhibit greater potential for closer cooperation, whereas the Kashmir group has a lower basis for cooperation. The results suggest that the establishment of transboundary conservation areas (TBCAs) and academic and scientific development can provide opportunities to enhance our understanding of the KH region and to collaborate across national boundaries. This case study explains that the indicator framework can be used as a reference for cooperative cross-border conservation in other regions worldwide.

Connectivity of Avicennia marina populations within a proposed marine transboundary conservation area between Kenya and Tanzania

Threatened ecosystems such as intertidal mangrove forests often span political boundaries and require cross-border conservation planning initiatives. Population connectivity is key to establish transboundary collaborative actions. In this study, we assessed genetic diversity and connectivity of mangrove populations in a proposed transboundary conservation area (TBCA) between Kenya and Tanzania, where human demography exerts increasing pressure on biodiversity and ecosystem services. East African mangrove ecosystems comprise a complex pattern of estuaries and coastal bays, with Avicennia marina as a major mangrove component. Our main objective was to test a hypothesis of overall migration directionality reflecting regional ocean surface current flows. Fourteen microsatellite markers in 670 A. marina trees revealed no overall significant difference in allele or gene diversity levels between populations but showed an overall effect of geographic distance with a gradient of admixed gene pools. Migration tests and Approximate Bayesian computations supported a customized stepping-stone model of overall south to north migration with bidirectional gene flow and admixture between adjacent bays near the Kenya-Tanzania border. Observed patterns of gene flow suggest an important effect of large rivers and connections via creeks. Our results indicate that relevance for conservation and management of mangroves areas may remain largely within a hydrological connectivity context of each bay, despite prevailing genetic estimates reflecting historically well-connected mangroves between bays. For sustainable management, populations must be considered complementary and not redundant. Hence, transboundary regions must primarily adhere to local contemporary conservation and management, and not solely rely on the assumption of strong regional connectivity built historically.

The making of a conservation landscape: the emergence of a conservationist environmental infrastructure along the Kwando River in Namibia's Zambezi region

AbstractThe Kwando Basin of north-eastern Namibia is firmly embedded in current national and international conservation agendas. It is a key part of the world's largest transboundary conservation area, the Kavango–Zambezi (KAZA) Transfrontier Conservation Area, and the home of seven community-based conservation areas (conservancies) and three smaller national parks (Mudumu, Nkasa Rupara and Bwabwata). While conservation agendas often start from the assumption that an authentic part of African nature is conserved as an assemblage of biota that has not been gravely impacted by subsistence agriculture, colonialism and global value chains, we show that environmental infrastructure along the Namibian side of the Kwando Valley has been shaped by the impact of administrative measures and the gradual decoupling of humans and wildlife in a vast wetland. The way towards today's conservation landscape was marked and marred by the enforced reordering of human–environment relations; clearing the riverine core wetlands of human habitation and concentrating communities in narrowly defined settlement zones; the suppression of specific, wetland-adapted subsistence practices; and the elimination of unwanted microbes with the help of insecticides. The interventions in the ecosystem and the construction of an environmental infrastructure have created a unique conservation landscape in the Namibian Zambezi region, which provides the foundation for its popularity and success.

Fortress tourism: exploring dynamics of tourism, security and peace around the Virunga transboundary conservation area

This paper examines the role of tourism in promoting peace around transboundary protected areas (TBPA) in conflict-affected regions through a case study of the Virunga TBPA straddling the Democratic Republic of Congo, Rwanda and Uganda. Also praised as ‘peace parks’, TBPAs embody the rationale that stimulating a tourism economy in shared conservation spaces will provide incentives for formerly antagonistic states and actors to cooperate. Virunga TBPA exemplifies this strategy by promoting high-end gorilla tourism in a region scarred by longstanding conflict. Drawing on twelve months of fieldwork, we found that these optimistic aspirations are contradicted by militarisation of the three National Parks constituting the TBPA, as well as prevalence of violence and political segregation among the countries. As park authorities sell ‘feelings of security’ by framing their neighbours as threats in order to attract visitors, intrastate competition and conflict intensifies. Peace tourism rhetoric and revenues allow the governments to justify and finance the militarisation as necessary to protect ‘their’ tourists while concealing their security interests in protecting national borders. This contradiction between tourism’s ostensive ‘peace dividend’ and the violence it generates within transboundary conservation efforts poses the question: what kind of ‘peace’ can be generated through tourism, and for whom?

The evolution of regional wildlife conservation, environmental protection and anti-poaching law in the Southern African development community

Environmental laws in Africa have their roots in the political economy of colonialism. This article examines the evolution of wildlife crime and conservation institutional framework in the Southern African Development Community (SADC) region. SADC countries have ratified multilateral environmental agreements and embraced Transboundary Conservation Areas. However, SADC states are hesitant to ratify treaties that make inroads into their sovereignty. Classification of poaching as a transnational organised crime is essential in effectively combating this crime. Policy recommendation on the effective use of wildlife instruments is made. It is recommended that the SADC Tribunal be resuscitated with jurisdiction over transnational environmental issues.

Abundant herds: Accumulation, herd management, and land-use patterns in a conservation area

North-eastern Namibia’s Zambezi Region became part of the world’s largest transboundary conservation area in the early 2010s: the Kavango–Zambezi Transfrontier Conservation Area. While wildlife numbers and wildlife-based tourism are increasing rapidly in this conservation zone, cattle herds and livestock-based economies are expanding as well. More than conservation and wildlife-based tourism, cattle husbandry is a project of the local population and of the local elite in particular. Cattle are an expression of wealth and are regarded as a means of saving. At the same time, cattle can be used to plough fields, pull sledges, and produce milk and meat for home consumption and also for sale. Cattle also fulfil important social functions; they are necessary for bridewealth payments and are used in cattle loans with which wealthy herd owners furnish poorer relatives. Recent investments into self-financed boreholes have opened new rangelands for the wealthy, while the expansion of conservation areas in the region’s wetlands and the establishment of wildlife corridors have rendered other rangelands challenging due to prohibitions and increasing incidences of human–wildlife conflict. The needs and practices of expanding cattle husbandry often conflict with the demands and challenges of conservation and conservation-related tourism.This contribution describes the emergence and expansion of cattle husbandry in a region which had hardly any cattle before the 1960s and which has seen a major expansion of conservation areas and a subsequent refaunation since the 1980s. The contribution analyses current cattle ownership patterns and management practices. We argue that livestock husbandry and conservation have to be considered together and not as competing land-use strategies that need to be kept apart but as separate visions and aspirations of different stakeholders relating to the same landscape.

Identifying transboundary conservation priorities in a biodiversity hotspot of China and Myanmar: Implications for data poor mountainous regions

Difficult to study species that inhabit inaccessible terrain, present significant challenges in obtaining accurate ecological, distributional, and conservation information. To address these challenges, we used an effective set of time- and cost-efficient methods including interview-based surveys assisted by Google earth 3D maps to document the distributional range of 32 native animal taxa in the biodiverse but difficult to access Gaoligong Mountains (GLGMS), located on the northern Sino-Myanmar Border. Five threatened flagship species, including the black snub-nosed monkey (Rhinopithecus strykeri), the Skywalker hoolock gibbon (Hoolock tianxing), Shortridge's langur (Trachypithecus shortridgei), Sclater's monal (Lophophorus sclateri) and the Mishmi takin (Budorcas taxicolor) were selected for intensive surveys and used as surrogate taxa to study community biodiversity. Field surveys of each species were conducted to determine their presence/absence and to confirm the reliability of species distribution data obtained from interview-based surveys. Multicriteria Decision Analyses were used along with data on habitat suitability (MAXENT) to prioritize transboundary conservation areas. Our results indicate that approximately 83.4% (10,398.7 km2) of the remaining habitat with high biodiversity conservation value in the GLGMs is unprotected. This includes six large zones located along the northern Sino-Myanmar border, separated by rivers and human settlements. These areas should be designated as a transboundary World Nature Heritage Site, national parks, or wildlife sanctuaries. This study presents a reliable, rapid and integrative method for developing informed policies for conservation prioritization in data poor areas, which can be applied successfully to assess conservation priorities in other mountainous regions where obtaining data on biodiversity is difficult.

Mangrove cover and cover change analysis in the transboundary area of Kenya and Tanzania during 1986–2016

ABSTRACTMangrove forests are among the most threatened ecosystems on earth. Some of these forests traverse national boundaries complicating their management due to differences in governance structures between countries. To improve the management of transboundary species regular monitoring is essential. Remotely sensed data were used to estimate forest cover and analyze conditions of mangroves in the proposed transboundary conservation area (TBCA) between Kenya and Tanzania. Image analysis was performed using unsupervised and supervised classification methods. The transboundary mangroves cover an estimated 11,906 ha; 55% being in Kenya, 45% in Tanzania. Ceriops tagal, Avicennia marina, and Rhizophora mucronata species co-dominate the mangroves of the transboundary area. The hotspot for loss and degradation of mangrove in the TBCA is Vanga in Kenya with a loss of 27 ha/yr. Harvesting of mangrove wood products have contributed to the loss of mangroves in the transboundary area. TBCA formation could play a critical role in ensuring sustainable mangrove resources utilization.
