Socio-economic, political, and institutional sustainability of agroforestry in Alta Verapaz, Guatemala
Promoting sustainable agricultural practices such as agroforestry (AF) could improve long-term productivity, enhance a sustainable rural livelihood and reduce pressure on natural resources and ecosystems in the tropics. However, AF seems to have adoption problems due to external market forces, lack of skills, financial resources and know-how ending in low flexibility and discontinuity of farmers in practicing AF. The objective of this study is to identify social, institutional, and economic factors that influence the adoption of AF on the household and community level, taking the region Alta Verapaz in Guatemala as a case study. Alta Verapaz is amongst the poorest regions in the country but also a tropical biodiversity hotspot where current agricultural practices are threatening forest environments and social development objectives. Our study explores how capital accessibility and institutional incentives are related to farmer’s livelihood sustainability and AF compositions. The methodology is composed by semi-structured interviews with nineteen farmers and field observations. The interviews have been analysed based on a qualitative content analysis by using the inductive category development. Based on these outcomes, the study found that human and economical capitals are favoured in communities were institutions are present especially through AF training offers, creation of farmers cooperatives and economic incentives. The role of institutions resulted to be crucial in the promotion of organic AF methods, forest protection and creation of long-term income. The combination of agricultural diversification with institutional incentives is one key livelihood strategy adopted by the farmers in order to achieve a socio-economic and ecological sustainability of their households. The further promotion of community forestry projects, expansion of networks and ongoing agricultural trainings as well as the diversification of agricultural systems could be beneficial for farmers in Alta Verapaz
Botanical diversity, structure and composition in cocoa agroforest systems in Alta Verapaz, Guatemala
The tree composition in cocoa agroforestry systems (CAFS) in Guatemala is valued for providing a number of ecosystem services. Despite the importance of the trees in these systems, little is known about the tree species richness and its contribution to the conservation of diversity. We studied the botanical composition of CAFS of different ages in the Alta Verapaz department of Guatemala. In total, 70 survey plots with a size of 2500 m2 were established. An inventory was carried out in each sampling unit, recording the tree species present and measuring the diameter at breast height (DBH 1.30 m) and the height of each tree. The Importance Value Index (IVI) was calculated and species richness and the similarity between sites were evaluated. A total of 2519 trees, belonging to 59 species and 34 families were identified. The species with the highest IVI was Gliricidia sepium (Jacq.) Kunth. The CAFSs with the highest and lowest species richness were those of 9-12 and 27 years old, respectively (H´=1.99, H´=0.34). This behavior can be explained by the fact that growers work to enrich the agroforestry systems with a broad diversity of species in the first years which they then begin to harvest at around 16 years of age. A discriminant analysis of principal components (DAPC) and the Jaccard Similarity Index were used to show that several AFS were similar in terms of composition and botanical diversity. Given the tree diversity within the CAFS, these can be acknowledged as areas with good potential for the conservation of overall biodiversity. We recommend education programs for local growers about the benefits of shade management during the production cycle of cocoa to preserve the botanical composition and structural complexity of the AFS
