Comparison of Canopy Openness in Different Cocoa (Theobroma cacao) Production Systems in Alto Beni, Bolivia

Jacobi, Johanna; Schneider, Monika; Bottazzi, Patrick; Pillco, Maria; Calizaya, Patricia; Rist, Stephan.

Cocoa-based small-scale agriculture is the most important source of income for most farming families in the region of Alto Beni in the sub-humid foothills of the Andes. Cocoa is grown in cultivation systems of varying ecological complexity. The plantations are highly susceptible to climate change impacts. Local cocoa producers mention heat waves, droughts, floods and plant diseases as the main impacts affecting plants and working conditions, and they associate these impacts with global climate change. From a sustainable regional development point of view, cocoa farms need to become more resilient in order to cope with the climate change related effects that are putting cocoa-based livelihoods at risk. This study assesses agroecosystem resilience under...

Microbial biomass and cellulase activity in soils under five different cocoa production systems in Alto Beni, Bolivia

Niether, Wiebke; Maldonado, Carla; Silva, Erika; Schneider, Monika; Gerold, Gerhard.

Cocoa (Theobroma cacao L.) grows naturally as an understory tree in tropical forests and produces well under shaded and non-shaded conditions. It is cultivated by small scale farmers in South America under various conditions, ranging from monocultures to different kinds of agroforestry systems. While in monocultures it is exposed to direct sunlight, one or various tree species shade the cocoa in agroforestry systems. Also organic cocoa cultivation is becoming more and more popular due to premium prices and increasing ecological consciousness. In Alto Beni, Bolivia, the Research Institute of Organic Agriculture (FiBL) and local partners have established a long-term field trial to compare cocoa production systems. The bi-factorial randomised block design...

Cocoa is one of the most important crops of the ‘‘Alto Beni’’ region in Bolivia. This crop is produced in different systems, among them monoculture and agroforestry. In order to determine the effect of the production system on microbiological soil characteristics, we measured microbial biomass carbon, microbial biomass nitrogen and cellulase activity and we determined the microbial quotient in soil under five different cocoa production systems (conventional monoculture, organic monoculture, conventional agroforestry, organic agroforestry and successional agroforestry) and in fallow plots. The measurements were carried out in dry and rainy season. Soil from fallow plots and soil under agroforestry had higher microbial biomass than soils under monocultures,...

Selección de diferentes sistemas de producción de cacao (Theobroma cacao, Malvaceae) por aves en Alto Beni, Bolivia - una prueba de cafetería en el campo

Naoki, Kazuya; Gómez, M. Isabel; Schneider, Monika.

El cacao (Theobroma cacao, Malvaceae) es una especie nativa de Sudamérica, y se considera que su cultivo cumple un rol importante para la conservación de biodiversidad. Se estudió la selección de aves entre cinco sistemas de producción de cacao y barbecho, a través de una prueba de cafetería en Alto Beni, Bolivia. Las aves fueron cuantificadas por medio del conteo de punto modificado durante la época seca. Se registraron 239 visitas de 43 especies de aves pertenecientes a 18 familias. El número de especies y la frecuencia de visitas de las aves estuvieron relacionadas positivamente con la complejidad de la estructura vegetal y la diversidad de árboles, disminuyendo desde el barbecho, el sistema agroforestal sucesional (SAFS), los sistemas agroforestales,...

Bolivia's local organic market and how it might be affected by the new national organic legislation 3525/06

Cocoa and total system yields of organic and conventional agroforestry vs. monoculture systems in a long-term field trial in Bolivia

Zschocke, Arnd.

The booming demand for organic products leads to high growth rates in this sector, especially in exporting countries. This study investigates how organic legislation in Latin American countries, which is intended to support the export sector, can also influence the local market. This is done through a case study for Bolivia, its new law 3525/06 and its national market for organic products. The general situation in Bolivia is described briefly, the new law is analyzed, and an analysis of the national market for organic products is presented. The results are that the new law is very progressive and allows easier access to organic certification for the internal market. Nevertheless, the local organic market is still a very small niche market and completely...

Schneider, M.; Andres, C.; Trujillo, G.; Alcon, F.; Amurrios, P.; Perez, E.; Weibel, F.; Milz, J..

Cocoa (Theobroma cacao L.) is produced in systems of varying complexity ranging from monoculture with temporary shade to highly diverse agroforests. Producers have to weigh high cocoa yields in the short to medium term in monocultures against higher total system yields in the short term and sustainable production systems in the long term in conjunction with ecosystem services in agroforestry systems (AFs). More long-term data on the comparative agronomic, economic and ecological performance of differently managed cocoa production systems is required to make sound recommendations to farmers. This paper describes the only long-term field trial worldwide comparing different cocoa production systems under conventional and organic management. The factors (i)...

Die Agroforstwirtschaft kann zum Schutz des Bodens, der Biodiversität, zur Ernährungs- und Einkommenssicherheit sowie zur Resilienz gegenüber dem Klimawandel beitragen. Kakaobauern in Alto Beni in Bolivien setzen verschiedene Varianten von Agroforstsystemen ein, und viele haben die Bio-Zertifizierung. Um die verschiedenen Anbausysteme zu vergleichen und herauszufinden, was die Rolle der Bio-Zertifizierung ist, wurden für diese Studie Daten in Kakaoparzellen erhoben und Interviews mit Kakaoproduzenten durchgeführt. Neben der Biodiversität waren auch die Kakaoernten und die Einkommen der Familien höher, welche ein Agroforstsystem hatten. Die Interviews zeigten, dass die Bio-Zertifizierung die Kakaoproduzenten motivierte, Kooperativen zu gründen, die Wissen...

Cocoa Yield Development of Different Sites, Varieties, Production Systems and Years, in Alto Beni, Bolivia

Cocoa agroforestry systems vs. monocultures under conventional and organic management - results from tropical Bolivia

Schneider, Monika; Perez, Eucebio; Alcon, Freddy; Choque, Romero; Trujillo, German; Andres, Christian.

One of the most essential limiting factors of cocoa (Theobroma cacao L.) productivity worldwide is pests and diseases. Each of the major production regions has its specific pests and diseases. Reported yield losses range from minor to almost 100 per cent. In Alto Beni, located in the Amazonian watershed of the department La Paz, Bolivia, the Research Institute of Organic Agriculture (FiBL) and its local partners are addressing several problems of cocoa producers using a participatory technology development approach. Problems were identified in a participatory way and are, in order of priority, i) to reduce the incidence of pests and diseases, mainly the cocoa mirid (Monalonion dissimulatum) and Frosty Pod Rot (Moniliophthora roreri); ii) to evaluate the...

Bolivian Rhinotragini IX: new genera (Coleoptera, Cerambycidae)

Andres, Christian; Milz, Joachim; Seidel, Renate; Trujillo, German; Alcon, Freddy; Weibel, Franco; Schneider, Monika.

Cocoa is one of the most important export commodities for many developing countries and provides income for millions of smallholders. The expansion of cocoa production has resulted in habitat destruction, biodiversity loss, and soil degradation. The prevalent cocoa production systems worldwide are conventional monoculture full sun systems. Agroforestry systems are argued to be a viable strategy for sustainable cocoa production. However, data-based information on advantages and limitations of different cocoa production systems is limited. Pairwise comparisons on the long-term performance of cocoa monocultures and agroforestry systems under conventional and organic management are inexistent. FiBL is pioneering to fill this knowledge gap with a unique...
