Previous issue date: 2014-06-30 / Mozambique is in the process of agricultural expansion, particularly in the areas
of predominance of Miombo Biome, mostly located in the northern part of the country,
driven by the trilateral cooperation program (ProSAVANA) involving Mozambique,
Brazil and Japan. Some studies were already conducted by this program, for instance,
related to the adaptability of maize and soybean seeds in this area. This study aims to
analyze, by the biophysical point of view, the favorability of the agricultural expansion
in the northern part of Mozambique in the scope of ProSAVANA, based on the Japan-
Brazil cooperation program (PRODECER) experiences in the western part of Bahia. As
basic materials, digital elevation models from the Shuttle Radar Topography Mission
(SRTM) were used to generate hypsometric and slope maps from both sites, Tropical
Rainfall Measuring Mission (TRMM) to compare rainfall data from both sites, data
from MODIS/Terra (MOD13Q1) sensor to compare the structure of the most
representative biome from both regions. Spatial database containing watershed
boundary, forest reserves and soils types were also considered. Techniques of digital
image processing, spatial analysis and spatial modeling available in the ENVI 4.8TM and
ArcMapTM 10 software packages were used. For the best performance of the EVI data,
the Double Logistic filter available in the TIMESAT 3xTM software was applied. Data
were analysed based on statistical methods of frequency, histogram and regression. As
results, a map of suitability for agricultural expansion areas based on physiographic
parameters were obtained over 4.8 million hectares (73 percent of the total area) as well
as a database with information of the physical conditions of the both region. The
method used here was relatively simple and can be reproduced for other similar
researches. / Mo?ambique encontra-se em processo de expans?o agr?cola, em especial, nas ?reas de predom?nio do Bioma Miombo, localizadas, em sua maior extens?o, ao norte do pa?s, impulsionado pelo programa de coopera??o trilateral envolvendo Mo?ambique, Jap?o e Brasil, denominado ProSAVANA. Alguns estudos j? foram conduzidos por esse
programa, por exemplo, relacionados com a adaptabilidade das sementes de milho e sorgo na regi?o norte de Mo?ambique. Esse estudo procura analisar, sob ponto de vista biof?sico, a favorabilidade ? expans?o agr?cola da regi?o de predom?nio do bioma Miombo ao norte de Mo?ambique (Corredor de Nacala) no ?mbito do ProSAVANA, ?
luz da experi?ncia do programa PRODECER do oeste da Bahia. Como materiais b?sicos, foram utilizados os modelos digitais de eleva??o da Shuttle Radar Topography Mission (SRTM) na gera??o de mapas de hipsometria e declividade, Tropical Rainfall Measuring Mission (TRMM) na an?lise comparativa de dados de precipita??o, dados do sensor MODIS/Terra (MOD13Q1) na compara??o da estrutura da vegeta??o
predominante nas duas regi?es (oeste da Bahia e Nacala), al?m do banco de dados espaciais contendo dados sobre as bacias hidrogr?ficas, reservas florestais e solos. Foram utilizadas t?cnicas de processamento digital de imagens e an?lise espacial dispon?veis nos aplicativos ENVI 4.8 e ArcMap 10 e ferramentas de modelagem de
dados geogr?ficos. Para uma melhor an?lise dos dados EVI, usou-se o filtro Log?stica Dupla dispon?vel no programa TIMESAT 3.x, que possibilitou a suaviza??o dos ru?dos presentes nesse tipo de dados. Os dados foram analisados com base em m?todos estat?sticos utilizando a regress?o linear e an?lises de frequ?ncia e histogramas. Como
resultados, obteve-se um mapa de ?reas favor?veis ? expans?o agr?cola sob ponto de vista fisiogr?fico, na regi?o norte de Mo?ambique, avaliadas em cerca de 4.8 milh?es de
hectares (73% da ?rea total), al?m de um banco de dados contendo informa??es sobre as condi??es f?sicas de ambas regi?es. O m?todo utilizado nesse estudo foi relativamente simples e pode ser estendida para outras pesquisas similares.
