Xai-Xai IDP – INTRODUCTION
5 km deep in the hinterland including the environmentally sensitive strip of the coastal dunes of about 50 km2.
Almost at the very beginning, the photo-metric method was accepted as most appropriate for the preparation of the relevant maps requiring the line maps presentation, which proved to be optimal for the preparation of the IDP. First contacts in that direction were made with the relevant national institution DINAGECA from Maputo. However, since DINAGECA was not supplied with an aeroplane and equipment needed for making aerial photos, it was decided that the specialised companies from the neighbouring RSA should be asked for help. The best offer was received from the Aerial Azur company from Pretoria who obliged to make aerial photos and maps, and deliver them in a digital and hardcopy format in the scale 1:5,000 within the extremely short period of time. Total costs amounted about 10% of the planned budget of the entire IDP, which was acceptable.
Aerial photos were made on two occasions, in April and May 1998, whereas maps were delivered in the beginning of July 1998. Aerial photos and maps were of high quality with contour lines at the distance of 2.0 m enabling the high-quality diminishing or enlarging of the maps (besides the basic scale of 1:5,000) in proportion up to 1:3. After an adequate adaptation of lines and marks, the legible maps prepared in the scale 10,000 and 1:15,000 were used for various analyses and structural presentations. The detailed plans were elaborated on maps in the scale 1:2,000, and even manually elaborated in the scale 1:1,000, for the middle part of Xai- Xai Beach.
Aerial photos in the scale 1:15,000 were primarily used for the detailed vegetation cover and land-use analyses. For the analysis, preparation and presentation of thematic maps, i.e. suitability analysis, hard copies and manual elaboration methods were used since the application of the GIS methodology and the use of maps in a digital format would have required much more time and financial means to be invested in the training of national experts. In order to prepare a quality presentation, manually prepared thematic maps were later on scanned and elaborated in a colour technique using a PC.
Upon presentation and adoption of the IDP, all thematic maps were delivered to the relevant municipality institutions prepared in the original scale and poster format aiming as much as possible to a reliable implementation of the planning guidelines.
1.4 Assessment and Harmonisation with other Relevant Projects
In the First Phase of EAF/5 in Mozambique the Coastal Profile and ICAM Strategy for the Xai - Xai District Coastal Area have been elaborated and adopted by national and local authorities. The IDP is actually the continuation of the ICAM Management Strategy. The relevant parts of this report should be cited, because the concept of the IDP is based on them. Besides, it would provide better understanding of the modifications made while elaborating the IDP. In general, most of modifications followed the better and more accurate information basis, provision of aerial photos and preparation of detailed maps, and, being most important, the better integration of the wider scope of sectoral inputs into the IDP outputs.
1.4.1 ICAM Management Strategy The Xai-Xai ICAM Strategy Framework is best described in the following paragraphs:
“The sand dunes are classified in Category III of IUCN and, consequently, need protection by virtue of their special characteristics, importance of national uniqueness, and opportunities provided for interpretation, education and public appreciation. In addition, they have both recreational and tourist values, and should be managed in a way as to be relatively free of human interference.
Based on the presented principles, the ICAM Strategy Framework for the Coastal Area of Xai- Xai should depart from the two major policy decisions, namely:
Biodiversity protection of naturally most valuable and environmentally sensitive areas of coastal dunes, the Limpopo river and the Baixos de Inhampura Reef,
