The Historical Context for Soil and Land Resource Surveys in Angola

Overview

Angola

The catalogue lists over 30 entries for Angola which includes material which has only indirect natural resource interest such as a livestock sector review; geophysical and geological material; and one volume on the agronomy of cotton. An examination of the specific pedological items suggests a grouping of the documents into the following groups:

  • four items which were completed during the 1950s;
  • four items which are representative of District surveys completed in mostly in the 1960s; and three later volumes which are regional summary volumes.;
  • two items which are also numbered as part of this series but are national in scope.

General Soil Reports from the 1950s

The archive holds the following general soil reports frokm the 1950's:

  • ID 1722. Solos De Angola., Botelho da Costa, J.V. and Azevedo, A. L, 1953, 373 pages, with a soft cover, includes a brief English summary at the beginning and an overview of the proposed system in relation to existing international classifications as Appendix VII, also in English. The volume sets out a proposed classification of the soils of Angola at great Group level. There are comprehensive maps included but the sites of profiles described and sampled are recorded along roads.
  • ID 1723. Solos de Angola E A Agriculture, Ario Lobo Azevedo, 1954, soft cover, 98 pages, with coloured map at a scale of 1:4 Million, folded into the text. There is no English summary.
  • ID 2657. Reconhecimento Da Baixa De Cassanje. Domingos H. G. Gouveia, 1956, soft cover, 155 pages, with a 1: M coloured map folded into rear cover, with two smaller coloured figures. There is no English summary. Soils are described as a part of complexes or associations.
  • ID 23689. As Laterites do Ultramar Postugues; (Laterites from the Portuguese Overseas Provinces. 1959. Soft cover 156 pages, with an eight page summary in English. This volume is mainly concerned with the use of laterite gravel in road construction in all the overseas jurisdictions of Portugal at time, including Angola.

Reconnaissance Level District Surveys during the 1960s

The WOSSAC archive holds four examples of District Level surveys undertaken in the period 1959 to 1969: These volumes share the following characteristics:

  • this material is in Portuguese, with no English summary;
  • the volumes are published in Lisbon;
  • coloured maps are folded inside the back cover;
  • the legend provides details at great group level with individual series/associations numbered and then described in the text;
  • each series is accompanied by analytical data

Specific details for each document is provided below.

Note, This publication series therefore has at minimum 59 volumes, of which the WOSSAC collection has a small sample only. The extent of the total collection (1-59) at least, are recorded inside the front cover of each volume. The District coverage includes Districts I to IV. It is not clear if there are other Districts mapped subsequently.

Regional surveys from the 1970s

Three later documents are also held within WOSSAC.

  • ID 1719. Geomorfologia, Solos E Ruralismo Da Regiao Central Angolana (Geomorphology, Soils and Ruralism of the Central Zone of Angola), Castanheira Diniz, A & de Barros Aguiar, F. Q. 1966. There is short English synopsis. Soft cover and 64 pages with many black and white pictures. A 1:1M geomorphology map is bound into the rear of the text.
  • ID 2648. Solos Aluviaia de Angola (Alluvial soils of Angola) Volume II Sedimentology and Mineralogy. Vieira e Silva, J. M. 1972. 11 pages with a soft cover. There is a short abstract in English. No maps.
  • ID 23516. Esboco Pedologico De Uma Regiao Centro Angolana. 1970. Soft cover 105 pages with two 1:1m dyeline maps bound into the text. This volume relates to the central core of the county and covers some Districts. The maps are difficult to interpret as one has the a legend but with no numbers or codes shown, and the other has the boundary lines but does not have a legend.

Project Documentation: Rangeland Reports

ID 8042, ID 8043, ID 8044, ID 8045, and ID 8046. These are project reports published in 1974 which provide a comprehensive Livestock Sector review. The work was carried out by two UK consultant organisations (APG Integrated Projects and Hunting Technical Services). The work was funded by the Coffee Diversification Fund of Angola. Volume I is the summary volume which provides a useful overview; Volume II which seems to be missing from the archive is the overall Livestock review; Volume III relates to Infrastructural Requirements; Volume IV deals with production prospects; and there is a separate volume (not numbered) on Meat Processing and Transport.

Loose Maps

The collection also holds a number of loose maps of Angola which are detailed below. None are of direct pedological interest. These include:

  • ID 15725, a 1969 road map of Angola at a scale of 1:1.5m. This map sheet is folded (cabinet 5) and is in poor condition;
  • ID 19679, a 1:1M scale topographic sheet of the Luanda area dated 1953; and
  • ID 19689, as above for the Cassamba area.

Gedological material

Seven items all dating from earlier than 1960, are held in the collection and brief details are noted below:
