description Publicationkeyboard_double_arrow_right Article 2008Publisher:Elsevier BV Authors: David M. Lansing; Pedro Bidegaray; David O. Hansen; Kendra McSweeney;David M. Lansing; Pedro Bidegaray; David O. Hansen; Kendra McSweeney;Abstract Where large-scale plantation agriculture spatially coexists with smallholding agriculturalists, they interact in multiple ways. A number of researchers have addressed the broader social, environmental, and economic consequences of smallholder/plantation relationships. Few studies, however, have examined the household-level conditions that drive smallholders to engage in plantation wage work. Research from off-farm and non-farm labor markets offer a number of clues to what types of households participate in plantation wage work. These studies, however, use aggregate economic categories and fail to consider the specific case of plantation wage work. Utilizing household survey data, this paper seeks to understand the relationship between smallholders and plantations by examining the household-level conditions that lead to engagement with plantation wage work within Costa Rica's Dos Novillos watershed. Our principle findings are: (1) agricultural assets are negatively predictive of engagement in plantation wage work; (2) a household's male labor availability is strongly predictive of a household's level of engagement in the plantation economy; (3) participation in plantation wage work appears to be an income strategy for asset-poor households more generally. Overall, this study finds little engagement in plantation wage work by smallholding agricultural households. Instead, this type of work appears to be the domain of asset-poor households that are marginally engaged in agriculture. This paper concludes by suggesting policy prescriptions and an agenda for future research in this watershed.

Despite the importance of the secondary forest (SF) in tropical areas, few studies have quantified the soil organic carbon (SOC) pool in Costa Rica. Most of the studies conducted to date in this country have focused mainly on changes in the soil C pool following conversion of forests to pastures, which is the predominant land use in the tropics. The aim of this study was to measure SOC concentration and pool in particle-size fractions down to 50 cm depth in four SF stands regenerating from different intensities of prior land use in loamy sand and sandy loam soils of northeast Costa Rica: (i) a gallery forest (GF), (ii) a 15-year-old SF enriched with commercially planted native trees (15SF), (iii) a 25-year-old SF (25SF), and (iv) an abandoned Theobromma cacao plantation >60 years old (60SF). Additional objectives were (1) to determine the relationship of SOC concentration with selected physical and chemical soil properties, and (2) to establish the key determinants of the depth distribution of SOC in order to identify meaningful trends in the SOC pool. The SOC pool was highest under the 60SF (221.4 Mg C ha−1) followed by the 15SF (212.1 Mg C ha−1), the 25SF (195.9 Mg C ha−1) and the lowest in the GF (183.5 Mg C ha−1). The SOC concentration decreased significantly from 59.7 to 94.1 g kg−1 in the 0–10 cm layer down to 31.0 to 45.5 g kg−1 in the 40–50 cm layer in all forest stands. The fine silt + clay fraction contained the highest values of SOC concentration in all forest stands. Soil texture and the age of the SF were identified as the main factors that explained the variability in SOC. The age of SF stand influenced the distribution of size class aggregates and SOC. This work was funded by the US Department of Energy. The first author thanks “Fundación ARAID” (Spain) for financial support during manuscript preparation. 11 páginas, 4 figuras, 6 tablas.-- Ecological management and sustainable development in the humid tropics of Costa Rica.

Alvarado; K. Molina; E. Ac Bol;Abstract This study is a qualitative exploratory analysis of the communities of Turrialba, Siquirres and Guacimo, which border the Parismina River of Costa Rica. The main purpose of this study is to identify the structural weaknesses that are present in the enterprises and the impact of these weaknesses on the capacity for raising the sustainable development competitiveness for the area. The study used semi-structured interviews and focal interviews as instruments of data collection. In addition, the study used the community of Los Santos, located in the Central Valley of Costa Rica, as a reference for comparison. The results indicate weaknesses related to the capacity of organization, financial knowledge, and low technological innovation that demonstrates that the enterprises have a greater direction towards spurious competitiveness.
