The objective of this study is to simulate the effect of population pressure, market integration, technological improvement and policy decisions on natural resource management in the hillsides of Honduras. To do so, we developed a bioeconomic model that combines dynamic linear programming with a biophysical model, then applied this model to a typical microwatershed. Over recent years, farmers from the selected microwatershed have followed a "vegetables-intensive" pathway of development. We ran different scenarios with historical data over the period 1975 to 1995 and then projected 25 years into the future from 1995 to 2020. The results of the bioeconomic model presented in this paper help to test a number of induced innovation hypotheses. Many of our... |

The reliability of food security rating, a variant of the more familiar wealth ranking procedure, was tested in a rural area of Western Honduras. Twenty workshop sessions were conducted in 13 different communities, with members of organized small farmers' groups attended by a large agricultural development project. Participants were all poor farmers with no more than 10 hectares of land. Participants, who generally knew each other well, were split into small sets and each set was asked to rate the food security status of all households in their organized group. Inter-rater agreement was assessed using the Kappa statistic, and related to other characteristics of the informants and workshop sessions, using multiple regression methods. Agreement was very poor... |

This study investigates the micro-determinants of land use change using community, household and plot histories, an ethnographic method that constructs panel data from systematic oral recalls. A 20-year historical timeline (1975-1995) is constructed for the village of La Lima in central Honduras, based on a random sample of 97 plots. Changes in land use are examined using transition analysis and multinomial logit analysis. Transition analysis shows that land use transitions were relatively infrequent in areas under extensive cultivation, but more so in areas of intensive cultivation; and that most changes favored intensification. Econometric analysis suggests that land use intensification was influenced by plot level variables (especially altitude, slope,... |

Farmers who live in fragile tropical hillsides often operate under severe resource constraints and face difficult tradeoffs when confronted with changes in production conditions. Using a bioeconomic linear programming model, this study simulates the effects of population, market, and technological changes on farmers income and on their management of the natural resource in a hillside area of Central Honduras.The results show that economic growth and agricultural intensification are not necessarily adverse for fragile environments. In fact, farmer incomes would be much lower and degradation much higher if intensive agriculture had not been adopted. Such a result, however, must be framed within a complex set of conditioning factors, among which agroecology... |

This paper investigates whether inferences drawn about a population are sensitive to the manner by which those data are obtained. It compares information obtained using participatory appraisal techniques with a survey of households randomly drawn from a locally administered census that had been carefully revised. The community map tends to include household members who do not, in fact, reside in the enumerated locality. By contrast, the revised official census is slightly more likely to exclude household members who actually lived in the surveyed area. Controlling for the survey technique, we find that the revised official census produces higher estimates of average household size and wealth but lower estimates of total village size or wealth, than the... |
