Policy Targets
The Convention on Biological Diversity (CBD) entered into force on 29 December 1993. It has 3 main objectives:
- The conservation of biological diversity
- The sustainable use of the components of biological diversity
- The fair and equitable sharing of the benefits arising out of the utilization of genetic resources
Policy Targets
The Convention on the Conservation of Migratory Species of Wild Animals is an environmental treaty under the aegis of the United Nations Environment Programme. CMS provides a global platform for the conservation and sustainable use of migratory animals and their habitats. As the only global convention specializing in the conservation of migratory species, their habitats and migration routes, CMS complements and co-operates with a number of other international organizations, NGOs and partners in the media as well as in the corporate sector. Migratory species threatened with extinction are listed on Appendix I of the Convention. Migratory species that need or would significantly benefit from international co-operation are listed in Appendix II of the Convention.

The 2030 Agenda for Sustainable Development, adopted by all United Nations Member States in 2015, provides a shared blueprint for peace and prosperity for people and the planet, now and into the future. At its heart are the 17 Sustainable Development Goals (SDGs), which are an urgent call for action by all countries - developed and developing - in a global partnership. They recognize that ending poverty and other deprivations must go hand-in-hand with strategies that improve health and education, reduce inequality, and spur economic growth – all while tackling climate change and working to preserve our oceans and forests.
The SDGs build on decades of work by countries and the UN, including the UN Department of Economic and Social Affairs
- In June 1992, at the Earth Summit in Rio de Janeiro, Brazil, more than 178 countries adopted Agenda 21, a comprehensive plan of action to build a global partnership for sustainable development to improve human lives and protect the environment.
- Member States unanimously adopted the Millennium Declaration at the Millennium Summit in September 2000 at UN Headquarters in New York. The Summit led to the elaboration of eight Millennium Development Goals (MDGs) to reduce extreme poverty by 2015.
- The Johannesburg Declaration on Sustainable Development and the Plan of Implementation, adopted at the World Summit on Sustainable Development in South Africa in 2002, reaffirmed the global community's commitments to poverty eradication and the environment, and built on Agenda 21 and the Millennium Declaration by including more emphasis on multilateral partnerships.
- At the United Nations Conference on Sustainable Development (Rio+20) in Rio de Janeiro, Brazil, in June 2012, Member States adopted the outcome document "The Future We Want" in which they decided, inter alia, to launch a process to develop a set of SDGs to build upon the MDGs and to establish the UN High-level Political Forum on Sustainable Development. The Rio +20 outcome also contained other measures for implementing sustainable development, including mandates for future programmes of work in development financing, small island developing states and more.
- In 2013, the General Assembly set up a 30-member Open Working Group to develop a proposal on the SDGs.
- In January 2015, the General Assembly began the negotiation process on the post-2015 development agenda. The process culminated in the subsequent adoption of the 2030 Agenda for Sustainable Development, with 17 SDGs at its core, at the UN Sustainable Development Summit in September 2015.
- 2015 was a landmark year for multilateralism and international policy shaping, with the adoption of several major agreements:
- Sendai Framework for Disaster Risk Reduction (March 2015)
- Addis Ababa Action Agenda on Financing for Development (July 2015)
- Transforming our world: the 2030 Agenda for Sustainable Development with its 17 SDGs was adopted at the UN Sustainable Development Summit in New York in September 2015.
- Paris Agreement on Climate Change (December 2015)
- Now, the annual High-level Political Forum on Sustainable Development serves as the central UN platform for the follow-up and review of the SDGs.
Today, the Division for Sustainable Development Goals (DSDG) in the United Nations Department of Economic and Social Affairs (UNDESA) provides substantive support and capacity-building for the SDGs and their related thematic issues, including water, energy, climate, oceans, urbanization, transport, science and technology, the Global Sustainable Development Report (GSDR), partnerships and Small Island Developing States. DSDG plays a key role in the evaluation of UN systemwide implementation of the 2030 Agenda and on advocacy and outreach activities relating to the SDGs. In order to make the 2030 Agenda a reality, broad ownership of the SDGs must translate into a strong commitment by all stakeholders to implement the global goals. DSDG aims to help facilitate this engagement.

Since the declaration of Sars-Cov-2 pandemic in March 2020, concerns have roused on the potential impacts on biodiversity and protected areas. Particularly in developing countries, high impacts were expected in and around protect areas as consequence of both direct and cascade effects, from drop of tourism revenues due to travel banning to consequences of global economic shrinking affecting government and international funding.
Papers and reports have been published on expected of observed impacts of Sars-Cov-2 pandemic (see for example Lindsey et al. 2020, Gaynor et al. 2020, Waithaka et al. 2021). Despite the efforts, homogeneous coverage of geographical and thematic scopes across the globe was not easy to achieve. In the meanwhile a series of survey were carried out to investigate the short and long term impacts on operators (e.g. Spencely 2020), protected areas (WCPA 2020) or more generally on biodiversity (e.g. FZS in preparation).
We addressed this topic from to two different angles. From a bottom up perspective, we engaged with regional observatories to investigate expected and observed challenges, responses and priorities for interventions at regional level. In parallel, we developed a theoretical indicator of vulnerability to the pandemic crisis (or a similar event) and identified available data for estimating the indicator at country and protected area level.

Le Plan de Convergence est un instrument de référence pour la gestion durable des écosystèmes forestiers de l’ensemble des pays membres de la COMIFAC.
Le défi ici est d’actualiser la dimension stratégique du Plan de Convergence de manière à ce qu’il englobe l’ensemble des priorités nationales et sous-régionales en matière de conservation et de gestion durable des écosystèmes forestiers, afin que soit renforcée la convergence entre intérêts nationaux et sous-régionaux.
De nombreuses consultations nationales et sous-régionales ont été conduites et ont permis de recenser les thématiques prioritaires et émergentes dans le secteur forêt environnement dans chaque pays et à l’échelle sous-régionale. Les thèmes prioritaires et émergents issus de ces consultations ont été pris en compte dans la détermination des six axes prioritaires d’intervention et des trois axes transversaux, ainsi que lors de la formulation des objectifs stratégiques et opérationnels et des résultats attendus.
Les objectifs stratégiques ainsi retenus guideront l’action de toutes les parties prenantes et de tous les partenaires du Plan de Convergence. La réalisation de ces objectifs à long terme contribuera à la concrétisation de la vision énoncée ci-dessus. Les impacts directs sont les effets à long terme qui permettent de mesurer la réalisation desdits objectifs stratégiques.
Les objectifs opérationnels guideront les actions que toutes les parties prenantes et tous les partenaires mèneront à court et à moyen termes pour concourir à la réalisation des objectifs stratégiques mentionnés précédemment. Les résultats correspondent aux effets à court et à moyen termes attendus de la réalisation des objectifs opérationnels.
Policy Targets
The Regional Strategy consists of the following three broad strategic areas. First, enhancing the region’s economic and business base by adding value to and commercializing its biological resources; and broadening and diversifying its industrial and manufacturing base. Second, ensuring that economic opportunities that emerge from “biotrade” and economic diversification do not lead to the unsustainable use of the region’s biodiversity and result in the loss of
biological resources and ecological processes. Third, developing and implementing biodiversity awareness, information and capacity building programmes; research and development initiatives; and sustainable financing arrangements.

The Gambia's biological resources are vital to the population’s economic and social development. As a result, there is a growing recognition in the Gambia that, biological diversity is a global asset of tremendous value to present and future generations. At the same time, the threat to species and ecosystems has never been as great as it is today. Species extinction caused by human activities continues at an alarming rate. Recognizing the need to conserve its biological resources, the Government of the Gambia has made a commitment to conserve at least 5% of terrestrial and inland water, and 10% of coastal and marine areas through systems of protected areas. Although in-situ conservation must be the first priority, the protected area network alone will not be sufficient to secure all of Gambia’s biodiversity for future generations.

One of the four existential threats humankind faces today is the loss of biological diversity. The others are climate change, food insecurity and poverty. Biodiversity, most simply stated, is life on Earth, the wealth of ecosystems, species and ecological processes that make up our living planet. It is humankind‘s living natural resource base, our biological capital in the global bank. Managing biodiversity sustainably is critical to the survival of humanity and thus needs to be given the utmost serious consideration by all actors. As is true globally, an unexampled rate of extinction of marine and terrestrial animal and plant species is plaguing Liberia‘s biological resource base. It now approaches a crisis proportion that requires urgent and concrete actions for mitigation. This crisis is impelled, almost invariably, by the direct and indirect threats of agro-industrial plantations of rubber, recently oil palm that are replacing the natural forests, giant logging concessions and related contracts, mining, unsustainable and destructive extraction and collection of firewood, charcoal production, shifting cultivation, uncontrolled hunting and fishing practices, ineffective community-based forest management and strategy, invasive alien plant species, , the lack of a national land use policy and strategy, climate change, poverty, the extreme lack of knowledge about ecosystem values, the lack of recognition and employment of local knowledge systems in natural resource governance and management and the lack of a national energy policy and strategy. The United Nations Convention on Biodiversity is the instrument for ensuring the conservation of biodiversity, sustainable utilization of its resources, and the fair and equitable sharing of benefits accruing from the use of these resources. Chapter II and Article 7of the Constitution of the Republic of Liberia, the National Environment Policy, and sectoral programmes, plans and policies are in agreement with the purpose of the Convention and Liberia has revised her National Biodiversity Strategy & Action Plan in keen adherence to the Strategic Plan for Biological Diversity 2011-2020 which was adopted in Nagoya, Japan, in 2010.At such the Revised NBSAP largely mirrors and details the vision and strategy for the Aichi Biodiversity Targets and a ten-year action plan (2015-2025) for conservation and sustainable management of biodiversity in Liberia. Preparation of the plan commenced in 2012 by the National Biodiversity Coordinating Section of the Division of Multilateral Environmental Agreements at the EPA, the lead Agency for environmental sustainability in Liberia. The document is a result of a Country Study that takes into account the political and socio-economic contexts that influence biodiversity management. It provides a summary of key issues, constraints and opportunities identified during the stocktaking and inventory phases of the Study. It further defines the strategic objectives, actions, outputs and indicators needed to achieve the overarching goals of communicating informed decisions about the implementation of the Convention nationally. The strategy identifies three key components to ensure effective implementation, one of which is Financial and Resource Mobilization Plan (FRMP). The FRMP provides a framework for sources of funds to implement programs and activities proposed in the Strategy, as well as the indicative budget required to implement the Revised NBSAP. The other implementation plans include Capacity and Technology Needs Assessment and Communication Strategy, which address, respectively, what capacity is required to implement the Strategy, and how effectively the Revised Strategy needs to be communicated to ensure participation of all stakeholders.

Nigeria houses a cornucopia of both plants and animal species which makes it very rich in biodiversity. The considerable levels of endemism and species richness in the country are due to a complex topography, favourable climate and wide range of habitats. These include but are not limited to coastal creeks of the Niger Delta, the rainforests of the Cross River basin and the mountains along the Cameroun border. The Atlantic Ocean forms the southern border part of Nigeria, and with its highly diverse marine and freshwater ecosystems. There exists an inland layout of an array of other forest ecosystems including the Sahel Savannah in the extreme North, Sudan Savannah, Guinea Savannah and Derived Savannah woodland. Species statistics showed that Nigeria has an endemic flora of 91 species belonging to 44 families with Rubiaceae accounting for the highest numbers. A list of faunal species was also outlined. According to the IUCN Red list 2013, Nigeria has a total of 309 threatened species in the following taxonomic categories: Mammals (26), Birds (19), Reptiles (8), Amphibians (13), Fishes (60), Molluscs (1), other Invertebrates (14) and Plants (168) (Sedghi, 2013). The categories of biodiversity related sites in Nigeria include: 7 National Parks of Old Oyo, Cross River, Gashaka-Gumti, Okomu, Chad Basin, Kainji Lake, and Kamuku; 27 Important Bird Areas including all National Parks and 60% the Ramsar sites; 11 Ramsar Sites; 2 World Heritage Sites of Sukur Kingdom and Osun Osogbo Grove; 994 Forest Reserves; 32 Game Reserves; 1 Biosphere Reserve; and many Sacred groves at varied level of protection. This document gave information on the status of biodiversity and its contribution to varied sectors of Nigerian economy including tourism, agriculture, water resources, health, commerce and industrial development. It showed how biodiversity impacts on the lives and livelihoods of the people as well. The value of biodiversity to Nigerians and the linkages it has on various sectors of the Nigerian economy was vividly shown. The threats to biodiversity, causes and consequences of biodiversity loss in Nigeria were also identified and analysed. It outlined the Policy, Legal, and Institutional Frameworks on conservation and sustainable use of biodiversity as an integral part of the national policy on environment. There was an elaboration of Stakeholders on Biodiversity management. This revised NBSAP was developed within the framework of stakeholder’s participatory approach involving series of plenary of multi-stakeholders workshop and peer reviews with over 500 stakeholders ranging from international and national experts to officials of sub national entities and managers of natural resources at the grass root. The consultative process included a detailed review of Nigeria’s first NBSAP (2001-2010) which provided valuable lessons and guidance for the formulation of this second NBSAP (2016 – 2020). Some of the key lessons learned from the first NBSAP include the lack of management structures for implementation of the NBSAP and the low level of awareness creation at Federal, State and Local governments during its preparation. Institutional linkages were not properly addressed in the implementation plan of action. Targets and Actions were not set to address identified major challenges although challenges were identified. Strategies for mainstreaming biodiversity into different sectors were weakly analysed in the first NBSAP. These shortcomings of the previous NBSAP form the bases of the lessons learned and the planning process of the current NBSAP has addressed them as critical in the implementation of the revised NBSAP. Nigeria’s Long Term Vision for biodiversity management is: ‘A Nigeria with healthy living environment where people live in harmony with nature and sustain the gains and benefits of biodiversity, integrating biodiversity into National programme aimed at reducing poverty and developing a secure future in line with the principle of ecological sustainability and social equity.’ The major focus of this vision is the consideration of genetic materials as a strategic but fragile resource to be conserved, sustainably utilized and perhaps more importantly to be deployed as natural capital for socio -economic development of Nigeria. Seven principles governing the national biodiversity Strategy were outlined. These are linked to Nigeria’s commitment to the CBD that is a genuine appreciation of biodiversity in national development and socio-economic welfare of the Nigerian people. They include specific principles that support global best practices in biodiversity management and in general, the environment and natural resources. Nigeria considers the five goals of the Global Strategic Plan for Biodiversity 2011-2020 very appropriate and applicable to its situation and adopted them to form the basis of the current NBSAP. It has also adopted 14 SMART National Targets with 21 Impact Indicators and 67 Actions with 123 Performance Indicators and 20 Programmes. Consequently, Nigeria’s current NBSAP is closely aligned to both the CBD Strategic Plan for biodiversity 2011-2020 and its Aichi biodiversity Targets and Nigeria’s unique Priorities and features.
Policy Targets
- Biodiversity is key to human survival and livelihood, especially in developing countries
such as Rwanda, where a large proportion of the population depend on natural resources for their livelihood.
- The present National Biodiversity Strategy and Action Plan (NBSAP) reflects a framework for conservation, sustainable use and equitable sharing of benefits from biodiversity use and ecosystem services of the country. It also provides a framework for maintaining the necessary environmental conditions to reduce poverty, ensure sustainable development and food security in the country.
- In Rwanda, root causes of biodiversity loss range from natural processes to anthropogenic actions. Results from recent research have shown that threats to biodiversity arise from loss of habitat due to encroachment for agricultural activities, over-harvesting of resources through poaching and deforestation, as well as increasing socio-economic activities such as mining, urban development, etc.
- Underlying causes are predominantly related to issues of land tenure and poor management of natural resources. In addition, a long-standing focus on increasing crop production at the expense of natural resources conservation also constitutes a key factor leading to intensive biodiversity loss.
- Nowadays, partnership between different stakeholders including government institutions,
development partners, private sector, civil society (NGOs) and local communities‟ organizations, is playing vital role in sustainable use and conservation of biodiversity.
- The NBSAP preparatory process was highly participatory, involving broad stakeholders‟ consultations. Three national workshops were organized which provided the basis for the national priorities for conservation, targets and strategic actions that collectively constitute the NBSAP substance.
- More emphasis has been oriented towards awareness building among stakeholders, in order to ensure that ownership of the NBSAP is widespread among them, and that responsibility for its implementation is widely shared. Furthermore, modalities for improving biodiversity policy and legal framework have been emphasized as well as capacity building for a better management of natural resources.
- The overall objective of the NBSAP development has been worked out as to preserve the national biodiversity in order to ensure that its various components are utilized in a sustainable manner for reaching socio-economic development of the nation and ensuring better livelihood of Rwandans.
The major objectives of the NBSAP are:
to improve environmental stability for natural ecosystems and their biodiversity;
to restore degraded ecosystems and maintain equilibrium among biological
communities;
to establish an appropriate framework for access to genetic resources and equitable
sharing of benefits arising from biodiversity use and ecosystems services; and
to improve policy, legal and institutional framework for a better management and
conservation of national biodiversity.

The Democratic Republic of São Tomé and Príncipe, aware of its role in the preservation of the Country biodiversity, which is a natural heritage of great importance for its people and for the world, has assumed the share of the responsibility incumbent upon it in this matter, despite the enormous constraints of economic and social order that the country has recently faced, due to the complex adjustment process to a new social and economic order, which was imposed by its independence. In a society still suffering from significant financial and economic difficulties, it is not always easy to decide on the option for immediate or deferred access to natural resources, all the more when it was not yet possible a full detailed assessment of the respective consequences. Only with the assiduous and careful efforts of the technical staff and people’s organizations, with the possible support from the political governance and the share of the international partners, it has been possible a greater restraint in the indiscriminate access to those resources and a better control of potentially detrimental actions for biological diversity. The progressive official and unofficial engagement is the guarantor of a committed on-going move towards a greater security of the biodiversity, through a sustainable use of the natural resources and the equitable share of the benefits derived therefrom. This engagement is enshrined in the country commitment and participation in the several international Agreements, Conventions and Protocols, related with the protection and valuation of biodiversity, and is strengthened by the general citizens perception of the relevance of its national natural heritage, so as in the global agreed effort, to safeguard biological diversity and environmental quality It is under this perspective that, once completed the First National Biodiversity Strategy and Action Plan of São Tomé and Príncipe (NBSAP I), with a clear achievement of most of the envisaged goals, now it is presented the NBSAP II, aware of its costs for the country and for international partners, but in the certainty, however, of the urgency in achieving the proposed objectives, to safeguard the valuable universal heritage of which we have de custody.

Section I - Background to the NBSAP This National Biodiversity Strategy and Action Plans (NBSAP) for Sierra Leone has been formulated since 2003 (NBSAP 2004-2010) to stem the alarming rate of loss of biodiversity and degradation of ecosystems in various ecological belts in the country. This reviewed version is effective for the period 2017-2026. The development of the NBSAP is a concept that was initiated and sanctioned by the Conference of Parties (COP) of the Convention on Biological Diversity in 2003 as a key requirement for parties of the convention to fulfil their commitment to conserve biodiversity, as required by Article 6 of the Convention. The reviewed strategy is consistent with two main categories, namely the thematic strategies and general measures, as guided by the Convention on Biological Diversity. The main themes are Wildlife, Forest Biodiversity, Agricultural Biodiversity, Freshwater, Marina and Coastal Biodiversity. The cross-sector strategies and cross-cutting issues include financial resources, policies, regulations and legislation, research and training, capacity building, public participation, planning, monitoring, conservation of protected areas, sustainable use, incentive measures, public education, impact assessment, access to technology, information exchange, sharing of benefits and indigenous knowledge. Sierra Leone became a signatory to the Convention on Biological Diversity, in 1994 in Bahamas. The development of the NBSAP is consistent with Agenda 21 of the United Nations, which is the Rio Declaration on Environment and Development. In 2003, Sierra Leone developed its NBSAP 2004-2010, but its implementation has had a fair share of successes and challenges. The World Bank, GEF, UNDP, the RSPB and Wetlands International are some of the organisations that supported the NBSAP 2004-2010. There is yet a huge backlog of project objectives to be achieved, which have been considered in the reviewing process. Key lessons were learnt from the development of the NBSAP 2004-2010 fed into the review and development of the NBSAP 2017-2026. Additional priority thematic areas were identified and addressed, such as intellectual property rights and climate change, collaboration between stakeholders, the problem of overlapping mandates and conflict of interest among government agencies, inter alia. The 20 Aichi targets were the key focus in all thematic presentations and group discussions during the national and provincial workshops. The key outcome of the workshops’ presentations, plenary and discussion sessions were the identification of the issues and gaps (Appendix V) in national and local efforts to conserve biodiversity.

L’Etat de Côte d’Ivoire, à l’instar des autres Etats du monde entier, est conscient de l’importance de la diversité biologique à telle enseigne que son ministère à charge de cette question se doit d’élaborer une stratégie pour la préserver. Afin d’aboutir à cela, plusieurs approches ont été menées. Dans ce contexte, il importe d’abord d’avoir un aperçu de la diversité biologique du pays. La diversité biologique terrestre et aquatique (ensemble des organismes, plantes et animaux) de la Côte d’Ivoire, dans l’état actuel des connaissances, comprend globalement 17.343 espèces. Les éléments constitutifs de la diversité biologique sont répartis entre deux types d’écosystèmes : - les écosystèmes terrestres : 12.647 espèces réparties entre ; 5.413 végétaux ; 6.019 invertébrés et 1.215 vertébrés ; - les écosystèmes aquatiques : 4.696 espèces réparties entre 2.102 organismes, 375 végétaux aquatiques et 2.219 animaux aquatiques. Les organismes terrestres comprennent des Virus, des Champignons, des Bryophytes, des Filicinophytes ou Ptéridophytes, des Progymnospermes et des Angiospermes signalées dans différentes phytocénoses dans les diverses zones climatiques et physiographiques du pays. Les virus identifiés sont au nombre de 101 espèces affectant les hommes, les plantes et les animaux. Chez les bactéries, ce sont 251 espèces. La flore des champignons comprend 557 espèces dont 356 espèces de champignons supérieurs parmi lesquels on compte 87 comestibles, 42 espèces de champignons inférieurs parasites de l’homme et 179 espèces de champignons inférieurs parasites des plantes cultivées. La flore des Bryophytes ou des mousses se trouve essentiellement dans les forêts des régions du sud du pays. Les inventaires signalent l’existence de 55 espèces réparties entre 32 genres, 6 familles, 5 ordres et 2 classes. Les Filicinophytes ou Ptéridophytes sont des cryptogames vasculaires signalés dans diverses zones écologiques. Elles sont représentées par 144 espèces reparties entre 60 genres, 25 familles, 7 ordres et 3 classes. La plupart de ces espèces se rencontrent en zone de forêt et 17 d’entre elles se retrouvent dans les zones de savane, surtout celles du genre Ophioglossum que l’on trouve sur des bowals et les dômes rocheux. Les Progymnospermes sont des plantes introduites et utilisées comme plantes ornementales ou essences servant à la fabrication de papier. Ils comprennent 17 espèces réparties entre 6 genres, 4 familles, 2 ordres et 2 classes. Les Angiospermes représentent 96 % de la flore ivoirienne avec 3711 espèces, 1 256 genres et 173 familles. La faune terrestre est caractérisée par une richesse importante. Cette faune compte 11 embranchements d’animaux repartis en 74 ordres, 203 familles, 769 genres et 7 234 espèces. Le groupe d’animaux qui compte le plus grand nombre d’espèces est celui des insectes avec 5 574 espèces. Ce groupe représente 79 % des espèces Protozoaire, il n’a été inventorié que 64 espèces pathogènes, ceci sans tenir compte d’espèces comme l’hématozoaire du paludisme, le trypanosome de la maladie du sommeil. Cet inventaire ne prend pas non plus en compte les espèces comme la paramécie, la vorticelle, etc. Les végétaux aquatiques sont composés de 375 espèces réparties en 89 familles et 212 genres. Les monocotylédones comprennent 129 espèces et 14 familles, les dicotylédones sont composées de 166 espèces et 54 familles et enfin les Ptéridophytes comprennent 80 espèces et 8 familles. La faune aquatique inventoriée est très diversifiée et comprend le zooplancton, les Annélides, les Brachiopodes, les Mollusques, les Crustacés, les Poissons, les Mammifères, les reptiles, les amphibiens et les oiseaux. Le zooplancton comprend 328 espèces réparties entre 134 genres et 79 familles. Concernant les annélides, polychètes enregistrent 434 espèces pour 144 genres et 35 familles. Les annélides oligochètes sont riches de 12 espèces réparties entre 10 genres et 4 familles. Les invertébrés autres que les Brachiopodes, Mollusques et Arthropodes sont composés de 30 groupes zoologiques, mais seules les Annélides Polychètes ont fait l’objet d’inventaire taxinomique avec plus de 434 espèces en milieux marin et lagunaire. Une seule espèce de Brachiopode et 601 espèces de Mollusques ont été inventoriées. Parmi les mollusques, l’on distingue les Gastéropodes, les Bivalves, les Scaphopodes et les Céphalopodes dans les eaux douces, saumâtres et marines. Les Crustacés se subdivisent en 4 sous classes, 13 ordres pour 302 espèces regroupées au sein de 61 familles. Ces Crustacés se rencontrent dans les eaux douces, saumâtres et marines. Le nombre d’espèces de poissons recensés est de 501. Ces dernières se répartissent entre 3 classes, 33 ordres, 276 genres et 130 familles. Il existe par ailleurs, 166 espèces exclusivement marines contre 152 espèces en eaux douces et 19 espèces en eaux saumâtres. 76 espèces vivent à la fois dans ces deux derniers milieux. Le reste des espèces sont capables de vivre dans les trois milieux à la fois. 11 espèces dont (Oreochromis mossambicus, O. macrodir, O. hornorum, et Tilapia rendalli.) ont été introduites dans le cadre de la pisciculture ou du contrôle biologique. Les mammifères aquatiques sont représentés par le lamantin (Trichechus senegalensis), les Loutres, les hyppopotames (2 espèces) et les Cétacés ou les baleines avec une (1) famille, deux (2) genres et 33 espèces sont aussi signalées dans les eaux marines. Les amphibiens comprennent 11 genres, 17 espèces et 2 familles. Les reptiles aquatiques comptent 31 espèces et les tortues marines présentent cinq espèces, toutes menacées. Enfin, les oiseaux enregistrent 165 espèces dont 35 espèces à statut particulier. La vie animale des zones humides présente des intérêts multiples en raison de sa grande diversité. Que ce soit en zones d’eaux douces, lagunaires ou d’estuaire, dans les marécages ouverts, les mangroves ou les forêts inondées, l’ensemble du règne animal y est bien représenté. La faune de ces milieux est constituée en particulier par des reptiles représentés par les sauriens (3 espèces), les tortues, les serpents, les oiseaux appartenant à des grandes familles telles les anatidés, les ardélites, les rallidés, les rapaces et divers limicoles, les poissons et les mammifères comme l’hippopotame nain (Choeropis liberiensis). Par ailleurs, il importe de relever les services fournis par les écosystèmes. Ceux-ci approvisionnent en bois d’œuvre et de service (60 espèces), en plantes médicinales (1500 espèces), alimentaires de cueillette (120 taxons), en plantes ornementales (147 taxons) et divers autres usages traditionnels (367 espèces). Ils servent de régulateurs du climat en limitant les émissions de gaz à effet de serre et ils contribuent à créer des richesses et offrent également des loisirs. Malgré tous ces bienfaits, les écosystèmes connaissent des menaces aussi bien naturelles qu’anthropiques. Les menaces naturelles comprennent le changement climatique, l’érosion côtière, l’envahissement par les espèces exotiques et les épizooties. Les menaces anthropiques sont dominées par la surexploitation, les prélèvements frauduleux, les destructions des habitats et les causes structurelles telles que la pauvreté, la faiblesse des capacités conceptuelles et opérationnelles. Face à ces menaces qui ne garantissent pas une utilisation durable des ressources biologiques pour les générations présentes et futures, des mesures de conservation et de sauvegarde ont été prises aussi bien au plan réglementaire, institutionnel, qu’au plan des programmations et des planifications. De plus un dispositif de conservation des ressources reposant sur les aires protégées, les réserves naturelles, les réserves botaniques et des collections ex situ a été mis en place. Mais l’érosion de la diversité biologique persiste. D’où la nécessité de la mise en place de nouvelles orientations découlant d’une vision claire qui fixe un but précis. Pour atteindre les objectifs fixés, il importe de définir des bases communes pour toutes les parties prenantes à travers les principes directeurs, les concepts et les approches dans la conduite des actions. « À l’horizon 2025, la diversité biologique de la Côte d’Ivoire sera gérée de manière durable en vue de l’équilibre des écosystèmes, de l’amélioration de la qualité de vie des populations actuelles et de la préservation de l’héritage des générations futures, en tenant compte de la dynamique sous régionale et des dimensions régionale et mondiale ». Telle est la vision d’où découlent au total six (06) orientations stratégiques avec des objectifs à atteindre d’ici à 2020. Ce sont :
- la sauvegarde des milieux naturels, de leurs fonctions et services;
- la préservation des diversités spécifique et génétique;
- le renforcement des infrastructures de conservation;
- la valorisation et l’utilisation durable de la diversité biologique;
- la mobilisation citoyenne et la diffusion de la connaissance sur le vivant;
- le renforcement de la coordination nationale et de la coopération internationale.
Toutes ces orientations sont traduites en actions prioritaires dans un plan pour lequel des mesures de réussite de la mise en œuvre ont été élaborées.
