Ecological Restoration and Sustainable Agricultural Landscapes

Background

This paper summarizes the talks of 2013 symposium held in Bogota, Colombia titled Ecological Restoration and Sustainable Agricultural Landscapes. The talks center around the pressing issue of balancing agricultural demands and the need to conserve biodiversity. They discuss current initiatives throughout Latin America that seek to both conserve and restore productive landscapes. Five talks in total are summarized touching on subjects ranging from agroforestry to silvopastoral systems to capacity building.

Shade-grown coffee in Puerto Rico: Opportunities to preserve biodiversity while reinvigorating a struggling agricultural commodity

Background

Coffee has been a traditional crop in Puerto Rico since the mid-1700s. As the global market became more competitive in the 20th century, the Puerto Rican government provided subsidies and policies to protect the sector as well as promoted the transition to shade grown coffee for higher yields in the 1980s. The researchers surveyed 100 farms and 5 agronomists to determine attitudes about this transition.

Development of the soil macrofauna community under silvopastoral and agrosilvicultural systems in Amazonia

Background

The Brazilian Amazon has experienced extensive land conversion from forests to cattle pasture, many of which now lay abandoned. Agro-forestry serves as one potential solution to this problem and this study examines the re-establishment of a diversified soil macrofauna in order to inform this approach.

The Contribution of Traditional Agroforestry to Climate Change Adaptation in the Ecuadorian Amazon: The Chakra System

Background

This article explores the amazonian-indigenous "chakra" agroforestry system, and its utility as a forest management practice that sequesters carbon, increases food security, grows valuable timber, and acts as a habitat connectivity. The size of these cultivated areas range from 0.4 - 4ha, and include species such as anioc (Manihot esculenta Crantz), banana (Musa paradisiaca L.), peach palm (Bactris gasipaes Kunth), fine-flavored cacao (Theobroma cacaoL.) and robusta coffee (Coffea canephora Pierre ex A. Froehner), and a variety of medicinals.

Tree species selection for a mine tailigns bioremediation project in Peru

Background

This article explains a project in southern Peru where tree plantings were used as bioremediation for treating tailings water from a copper mine. A variety of 25 tree species were selected for trial plantings on the site that could also be suitable for fuel and construction wood in the future.

Using artificial canopy gaps to restore Puerto Rican Parrot (Amazona vittata) habitat in tropical timber plantations

Background

This study tests whether or not man-made canopy gaps can restore native tree diversity as food sources for the endagered Puerto Rican Parrot (Amazona vittata). The site is located within a non-native blue mahoe (Hibiscus elatus) plantation in the Río Abajo forest in central Puerto Rico, where the researchers planted native species in assisted natural regeneration. The gaps were created in 20m x 20m plots by girdling and applying herbicide on non-native trees and by clearing leaf litter and vegetation, creating space for planted and naturally established advance regeneration seedlings.

Riparian restortion for protecting water quality in tropic agricultural watersheds

Background

In the Sarapui River watershed in southeastern Brazil, the water quality system was measured for six subwatersheds in the region.  In addition to measuring the subwatersheds, the entire watershed system was also measured and compared to a simulation model that included riparian zones throughout the river watershed.
