    本研究は,ナイジェリアのフルベ族の牧畜経済を,その生態的側面と彼らをとりまく政治経済的側面との両面から分析したものである.なかでもフルベ族の移牧形態,家畜群の管理と販売からなる牧畜経済を記述・分析することが中心となった.調査の結果,移牧フルベは雨季から乾季にかけて約8m下がる

    の水位の変化に対応して,家族総出で居住地を氾濫原に移動する生活様式をとり,彼らの牧畜活動は,伝統的な薬を利用した牛の繁殖や牛の夜間放牧などに特徴がみられることが明らかになった.また,フルベは牛の価格の高い家畜市を選択するだけではなく,病気の牛,不妊の雌牛など,群れの中で不必要な牛を適宜売却することから,市場経済の原理に強く依拠している.彼らは,結婚式や命名式などで使われる数頭の牛を除くと,3頭分の牛を売却して得た現金によって穀物などを購入して,一年間の生計を維持することができる.ナイジェリアのオイルブームによる経済成長をへて,フルベは伝統的牧畜形態を維持したままの自営牧畜を展開させてきた.

    In Nigeria, regionalism is often seen as something working against national integration, and the word ‘regionalism’ has tended to be used in a negative term to denote divisive tendancies. And this is very different from the situation in Japan where political and economic centralisation is so strong that the study of ‘regionalism’ have received considerable attention in recent years.
    The origin of regionalism in Nigeria dated back to the history of the establishment of the country as a political unit. In this paper, the author traced the history of the demarcation of Nigeria's international boundaries.
    The emergence of Nigeria as a political unit occurred in two stages. The first stage featured the establisment of the British trading posts and later protectorates along the sea coast and the River Niger. The second stage was the demarcation of boundaries between Nigeria and the neighbouring countries.
    During the first stage, Britain succeeded in securing economic and political interest in the Niger delta district, partly because she had established relatively strong trade relations with the people of the district, and partly because the Royal Niger Company had made treaties of protection with the people.
    The second stage occurred when the land boundaries were decided upon during the partition of Africa at Berlin in 1885. And in this scramble for territory, the emphasis was on effective occupation.
    In both stages, the question of consulting the local people never arose, and in mamy cases, the international boundaries split some ethnic groups into two different countries, or it forced peoples of different languages, different religions, and different outlook to life to amalgamate into one country. The problem of regionalism in Nigeria dates back to this forced amalgamation. However, Nigeria aims at destroying tribal based regionalism in several ways. One of which is the creation of more states.

    It is widely known that not only Lord Lugard who had not hesitate to say about quasi “heaven-born” superiority of the Northern Nigeria, but also many British administrators had acknowledged their preference for the northern Nigeria than southern Nigeria. It is discussed in this paper what the origin of this “British administrators' preference for the north (Nothern Nigeria)” is.
    Before the year of 1830 when the River Niger's mouth was discovered, the main British people who were active on the coast of the Bight of Benin and the Bight of Biafra were slave traders and explorers. Slave traders overwhelmed explorers in number, but as far as information is concern which they had brought in to the Britain, their cotribution was nominal. In contrast to this, explorers had brought many kinds of and large quantities of information about both of the South (coastal area) and the North (inland area). They wrote many reports and books, in which they depicted the northern area as highly organized Mahomedan countries where people were modest.
    About ten years after the discovery, many kinds of peoples began to come to both coastal and inland areas. Among those groups, the most important groups were non-slave traders, missionaries, and administrators. All these new-comers arrived to Nigeria with the information and knowledge which was available in Britain. That is; continual political coflicts in the south, and well organized Mahomedan Emirates in the north; wild “pagan” people in the south, and polite and honest islamic people in the north; highly humid weather in the south, and dry and relatively comfortable weather in the north.
    But as missionaries in the north had experienced failure of missionary work because of strong resistance by islamic people and they had succeeded in the south, they began to change their image of Nigerian people. Contrary to this, administrators whose main interest was to find the means to secure their country's economic and political interest over the new territory, felt no need to change their image of Nigeria. For them well organized society in the north seemed to be favorable for their future rule. And this is one of the most important reasons why British administrators in the north concentrated their attention upon establishment of administrative and taxation systems in the first stage of British administration, and the British administrators in the south did not.

    現在の気候条件からみれば森林が成立していても良いと考えられるカメルーン中部および西部の高地では,更新世末の乾燥化(森林の大幅な後退),完新世初頭の湿潤化(森林の回復)を経て, 2,000y. B. P. 頃には人為的な森林破壊が進み,遅くとも1,000y. B. P.頃にはかなり強度の農耕が行なわれていたと思われる.その後, 150y. B. P. 頃から牛牧畜民の侵入をうけて農耕民が急減し,その結果定期的に火入れされる牛放牧地の鉢大をみた地域と,それを免れかなり集約的な農耕が継続された地域とで,表土層の維持・更新状況に明白な差異が生じるようになった.現在両地域には,森林がきわめて少なく自然状態より著しく乾燥したみかけを呈するという景観上の共通点と,かたや低木と高茎草本がさまざまな割合で混在した景観,他方では樹木の極端に少ない草地・農耕地景観が,それぞれ卓越するという相違点とがみられるが,これらはともに,人為の作用の時代的・地域的な変化と良く対応する.さらに表土の人為的削剥の強弱は,更新世の古気候の産物である鉄・アルミナ硬化層や礫質堆積物の露出状況に差異をもたらしているが,それも現在の景観の地域的な差異の形成に関与しているようにみえる.

    2019年に西部ナイジェリアのヨルバランドの5州で、ヨルバ語でヒョウを意味するアモテクンという自警団が名乗りを上げた。かつて東部ナイジェリアのエフィクやイビビオ社会で活躍した秘密結社エクペ(ヒョウを意味する)に倣ったかのようであった。

    西部5州の知事たちは、アモテクン設立にあたり北部から来たフラニ牧畜民による農民襲撃を最大の理由とした。ヨルバランドからフラニ牧畜民を排斥するという地域主義的運動に展開しかねない危険性を感じ取った連邦政府は、連邦警察以外に警察権を行使できる組織はあり得ないとする法律的理由からその設立に待ったをかけた。

    州知事が指揮権を持つアモテクンは、かつて東部の森のなかで活躍した秘密結社のヒョウではなく、連邦政府の警察権を脅かす存在として認識されることになったのである。

    Recently the scholars studying conflict theories or peace building in Africa have tended to neglect the historical perspective of Africa. Without knowing the history of traditional kingdoms and chiefdoms, including slave trade, colonialism, and neo-colonialism, we cannot accurately understand serious problems with which African people are now confronted.
    Coups d'etat are common in Africa. Nigeria in particular, an oil-rich African giant, has experienced the military rule for about twenty-nine years since its independence. Why did the Nigerian officers decide to seize the power? Why did they desire to keep the power for such a period of time? And, why don't they intend to withdraw from the political arena? To answer these questions, we should consider the impact of British rule in Nigeria.
    The Nigerian army was originally established to conquer the native kingdoms and chiefdoms under the policy of British colonization. British rulers sometimes undermined the “rule of law.” Later the Nigerian army became the tool for traditional rulers, who started to work for the British rule in order to suppress their own people. New rulers of independent Nigeria learned how to use the military to defend their vested interests during 1960 through 1966. Therefore, it is the negative legacy of British rule that civilian and military regimes had not maintained “law and order” to save the lives of Nigerian people. So many civilians, being involved in armed conflict between Nigerian army and rebellions, were killed by the army.
    Samuel Huntington showed two conditions to avoid military intervention. According to him, the civil-military relation may be destroyed if the governments would not be able to promote “economic development” and to maintain “law and order” and if civilian politicians would desire to use the military power for their own political ambitions.
    As to the “economic development,” approximately 80% of Nigerian people suffer from poverty, whereas the retired generals enjoy their political power as well as financial business with a plenty of money. As mentioned above, the aspect of “law and order” has been also neglected by the regimes. After independence, civilian regimes used the military for their political interests and led the army officials into the political arena.
    Therefore, as suggested by Huntington, military intervention may be caused in Nigeria again if the Fourth Republic would neglect the importance of promoting “economic development” and of maintaining “law and order.” The Fourth Republic also needs to keep the army out of politics and the politics out of the army to avoid military intervention. Actually it is difficult to meet these conditions, because the group of retired generals still has strong influence over political and economical arenas.
