“…A map of Land Suitability Units (LSUs) for the growth of T. magnatum was derived by overlapping the wetness index and soil suitability map. The most severe limitation, whether soil or wetness, determines the overall suitability final class while limitations of the same degree are joined in the overall suitability class (Bydekerke et al, 1998).…”

Land suitability is the fitness of a given type of land for a specific use. Tuber magnatum Pico is one of the most valuable truffles present in Italy. The objective of this study was to assess the suitability of land to favour the growth of T. magnatum, using detailed soil spatial information, for the area around Piana Crixia (a town in Province of Savona, Italy). The work is based on land evaluation framework promoted by the Food and Agriculture Organization of the United Nations. Attributes of the physical environment (soil and wetness characteristics) were assembled and used for the suitability assessment. Each attribute was mapped using a geographical information system and classified on the basis of predefined requirements. Soil and wetness requirements for T. magnatum were identified using expert knowledge of highly productive truffle grounds and a land suitability map at a scale of 1:10,000 was produced by overlaying the generated soil suitability and wetness suitability maps.

“…Os indicadores climáticos foram estabelecidos com base nas características climáticas das regiões de origem (consideradas aquelas de ocorrência de cruzamento natural entre a cherimóia e a pinha) e dispersão comercial da atemóia; já os indicadores pedológicos foram definidos a partir de informações citadas na literatura e do reconhecimento das características dos solos de algumas regiões de produção dessa cultura e regiões de origem de outras espécies das anonáceas (Bydekerke et al, 1998). Os indicadores pedoclimáticos, que podem ser utilizados no zoneamento de qualquer região para o cultivo da atemóia, são demonstrados na Tabela 1; no entanto se utilizaram no presente trabalho apenas os indicadores importantes para o Estado da Bahia.…”

RESUMOA cultura da atemóia tem despontado como opção de exploração comercial no Estado da Bahia, mas a expansão de áreas produtoras está sendo realizada sem prévio conhecimento das suas exigências climáticas e pedológicas. Em decorrência disso, o objetivo deste trabalho foi realizar um zoneamento pedoclimático para o cultivo da atemóia no Estado da Bahia, com base em indicadores de clima e solo estabelecidos de acordo com as exigências da cultura. Constatou-se, a partir do cruzamento das informações entre os mapas temáticos climático e pedológico, que 19,3% do território baiano apresentam condições adequadas para o cultivo da atemóia. Áreas marginais e inaptas também foram identificadas cobrindo, respectivamente, 13,9 e 24,3% do estado. Verificou-se também que 42,5% das áreas do estado possuem restrições à exploração comercial desta espécie devido, principalmente, às limitações climáticas; entretanto, as áreas que apresentam apenas restrições quanto à deficiência hídrica do solo devem ter o cultivo incentivado pelo uso da irrigação uma vez que as condições ideais dos fatores pedológicos e demais fatores climáticos podem favorecer a obtenção de bons rendimentos.

However, the expansion of the cultivated area is being conducted without knowledge of the climatic and pedologic crop requirements. The objective of this work was to carry out a pedoclimatic zoning for atemoya cultivation in the State of Bahia based on established criteria of climate and soil according to crop requirements. By crossing the information between climatic and pedologic thematic maps, it was verified that 19.3% of the state territory exhibited appropriate conditions for crop production. Marginal and unsuitable areas were also identified, covering 13.9 and 24.3% respectively of the state area. Restrictions for atemoya cultivation were also observed in the major part of the territory (42.5%), which is caused mainly by climatic limitations. However, areas that present soil water deficiency only should have the cultivation encouraged by the use of irrigation since ideal conditions of the pedologic and the remaining climatic factors may be appropriate for obtaining high income.

“…Suitability assessment is a multi-criteria evaluation (MCE) process widely used in a variety of planning and decision-making situations including natural resources planning (Ponce-Hernandez, 1998), agriculture (Ceballos-Silva and López Blanco, 2003a,b;Bydekerke et al, 1998;Wandahwa and Ranst, 1996), waste disposal management (Basnet et al, 2001), recreational facilities setting (Kliskey, 2000), coastal zone management (Fabbri, 1998), definition of protected areas (Villa et al, 2002) and mapping fish grounds (Bergmann, 2004).…”

Assessment, planning and management for coral reef ecosystems are particularly challenging tasks, especially in developing countries. In this study, a methodological approach which integrates Geographic Information Systems (GIS) and Multicriteria Evaluation (MCE) for the development of suitability assessment models for a variety of uses of coral reef resources is discussed. Such an approach is sustained by an extensive use of local expert knowledge coded in the form of automated decision trees (DTs). The usefulness of the approach and the models developed is demonstrated by their application to the participatory assessment and resources planning at "Alacranes Reef National Park" (ARNP), Yucatán, México. Overlaying of resulting suitability maps was also applied for identifying potential conflicting areas.
