| The possibility of cultivation of the giant kelp Macrocystis pyrifera was successfully experienced in France on the north coast of Brittany. In order to evaluate the possibility of eventual acclimation on the French shore, study tour was undertaken on the Californian and Chilian coasts on main kelp beds. Effects of such beds on general ecology, fish resources, sportfishing, navigation, beach cleanliness, and alginates industry are analyzed. Factors controlling kelp distribution and hazards of wide distribution are discussed. Macrocystis seems to be able of developing and maintaining a large standing crop and to contribute to a large and stable associated fauna. The advantage of enhancing fishing greatly outweight the minor disadvantage of navigational... |

| Local ecological knowledge (LEK) can shed light on ecosystem change, especially in under-researched areas such as South Africa’s Wild Coast. However, for ecosystem planning purposes, it is necessary to assess the accuracy and validity of LEK, and determine where such knowledge is situated in a community, and how evenly it is spread. Furthermore, it is relevant to ask: does LEK add value to science, and how do science and local knowledge complement one another? We assessed change in woodland and forest cover in the Nqabara Administrative Area on South Africa’s Wild Coast between 1974 and 2001. The inhabitants of Nqabara are “traditional” Xhosa-speaking people who are highly dependent on natural resources for their... |

| A regiao dos Cerrados tem experimento, nas ultimas duas decadas (1960 a 1980), um substancial crescimento na sua densidade demografica, principalmente na sua area rural. Enquanto a populacao rural decresceu no Sudeste em 41%, neste periodo, o Sul teve acrescimo de 38%, e o Centro-Oeste, onde se concentram mais de 80% dos Cerrados brasileiros, experimentou crescimento de 51,5% (1). Tradicionalmente, as atividades agropecuarias da regiao baseiam-se no cultivo de culturas anuais, no gado de corte e pastagens, com enfase para as duas ultimas. A fruticultura constitui uma opcao viavel para os Cerrados, nao so pela sua boa rentabilidade, mas tambem pelo efeito minimizador das perdas de safras, quando feita em consorcio com as culturas anuais. O clima, a... |
