| 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... |

| 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... |

| A compilation of phycological literature published on Bolivian algae is presented together with an analysis of strengths, weaknesses, and needs in this field of investigation. An analysis of the nationality of authors, type, content, and geographic focus of the references shows that literature is largely produced by foreign scientist, concentrated on just a few areas of the country, or are biased toward particular algal groups, leaving ample room for more exploration. The Altiplano (high mountain plateau) and Amazon concentrate most of the publications, the phytoplankton and algae found in sediment cores, being the communities that have received more attention from scientists. Taxonomic references focus more on phytoplankton and tychoplankton communities... |

| Se presentan datos de avistamientos del Mirlo de Agua de Barba Roja (Cinclus schulzi) en la Cordillera de Sama, departamento de Tarija, Bolivia. Se recorrieron 17 quebradas, arroyos y ríos, pero solamente se realizaron 12 avistamientos en 4 cursos de agua, correspondientes a un mínimo de 10 individuos: 4 parejas, un individuo solitario y un volantón. Los mirlos fueron registrados en cursos de aguas claras, pero estaban ausentes en las porciones de los ríos contaminados con residuos de ganado. Se confirma la presencia de Cinclus schulzi en la Reserva Biológica Cordillera de Sama y su nidificación en el área. Además, se presentan datos sobre el comportamiento de alimentación y la interacción con otras especies. |

| 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... |

| Migration from the Bolivian Altiplano to the Amazonian lowlands poses a number of challenges related to climate change adaptation and disaster risk reduction. Alto Beni, located in the Bolivian Yungas at the interface between two altitudinal zones, is a critical area in this respect. Unsustainable land use practices are leading to soil erosion, shallow landslides, as well as forest and biodiversity loss. Settlers from the Altiplano see themselves confronted with an ecosystem that does not support the agricultural systems they were once used to. Soil degradation and government incentives have promoted migration further into the rainforest, creating pressure on local indigenous groups and biodiversity. The best-suited land use system for the fragile soils... |

| The global demand for cacao has recently increased. To meet this demand, the cultivated area has been expanded in tropical forest areas and production has intensified by replacing traditional agroforestry systems with monocultures. This has led to a loss of biodiversity in cacao-growing areas. More sustainable production systems such as agroforestry and organic managed systems are expected to yield less cacao, but by-crops and premium prices, respectively, might economically compensate for the lower yields. Here, we compared the productivity and the return on labor, that is the return per working day, of four different cacao production systems: agroforestry and monocultures under organic and conventional management. Cacao and by-crop yields, costs,... |
