RESUMO Por lo general, los historiadores de la ciencia reconocen la importaocia de Alexander von Humboldt en el desarrollo de la geografía moderna, si bien tal contribución especializada no es claramente desglosada de su multifacética producción científica. Con ocasión del bicentenario de su viaje a la América tropical, el papel de Humboldt en la formulación de las bases de una metodología analítica para la investigación geográfica, y su monumental trabajo sustantivo, lo mismo que su penetrante permanencia e inspiración en la tradición geográfica, deben acreditarse como justificación amplia y suficiente para su título de padre fundador de la geografía científica. Epígrafes: Humboldt, historia de la geografía, geografía moderna, metodología geográfica, exploración científica.ABSTRACT Alexander von Humboldt’s contributions to the development of modern geography are generally ackoowledged by historians of science, though not always stated precisely out of his many-sided scholarly production. On the occasion of the Bicentennial of his voyage to tropical America, Humboldt’s role in setting forth the foundation of an analytical methodology for geography as well as for his monumental substantive work, along with his pervasive and inspiring perrnanence in the geographical tradition, must be recognized as ample justification tu his title as founding father of scientific geography. Key words: Humboldt, history of geography, modern geography, geagraphical methodology, scientific exploration.

Using Data

This study tests the hypothesis of whether credit impacts productivity, and whether productivity in turn impacts market participation under a simultaneous modelling framework of credit, productivity and market participation, which has not been pursued in the literature. Using data from the Ghana Living Standards Survey Round 6, we applied a conditional mixed process estimation technique to correct for selectivity bias and unobserved endogeneity. We find that credit positively impacts productivity, which in turn positively impacts market participation. Furthermore, other determinants such as roads, public transport, radio and phone, and compliance with extension advice positively influence productivity while availability of markets and multiple cropping in a season increase the decision to sell maize. These findings imply that the transmission mechanism to transform the subsistence nature of Ghanaian agriculture into a sector characterized by commercial agriculture is to enhance access to credit, which in turn would stimulate productivity, which in turn would enhance market engagement.

The Tropics

There is a strong interaction between irrigation and crop improvement, irrigation creating new opportunities and challenges for plant breeders while depending on their progress for its full benefits to be realized. In temperate environments the primary emphasis is on raising yield potential, especially as irrigation enhances the use of agrichemical inputs. Efficiency of water and energy use through the modification of physiological processes and of sensitivity to stress at various stages of the life cycle is also sought. In tropical environments, breeding for greater yield potential and more comprehensive pest and disease resistance are still important. However, shortening the length of the life cycle, reducing its sensitivity to seasonal signals and increasing yield per day may be more important than raising yield per crop because of the scope for multiple cropping made possible by irrigation in the tropics in the absence of contraints by low temperatures.
