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.

The Campesino-to-Campesino agroecology movement of ANAP in Cuba: social process methodology in the construction of sustainable peasant agriculture and food sovereignty

Background

This article focuses on agroecology as a farming practice based upon principles rooted in the biology of a place and its organic matter. Agroecology has been promoted by community organizations and NGOs and is scaling up to national peasant organizations and social movements. This study looks at Cuba as a case study for La Via Campesina, a global peasant movement, and how agroecology has spread in Cuba from campesino-a-campesino, or peasant-to-peasant.

Direct seeding to restore rainforest species: Microsite effects on the early establishment and growth of rainforest tree seedlings on degraded land in the wet tropics of Australia

Background

In Queensland, Australia, three degraded sites (a high elevation site, mid elevation site and low elevation site) that were dominated by non-native grass were studied. The study looked at how six different methods of sowing affected the establishment and growth of small and large seeds, as well as how it affected weeds growth and re-establishment. Before the sowing treatments were conducted, the weeds, since it often outcompetes seeds/seedlings, were removed using herbicides. The sowing treatments created microsites that either consisted of the seeds being buried beneath the soil or placed above the soil.

Bridging the great divide: State, civil society, and ‘participatory’ conservation mapping in a resource extraction zone

Background

The author evaluates the outcomes of a participatory and inclusive mapping technique in a mineral extraction zone—the Cordillera Huayhuash—in the Andes of Central Peru. Knowing that land titling is often a source of mistrust and conflict between communities and the government, this technique offers a way to build counter-narratives to the unused territory story often told by state resource management agencies in charge of granting concessions to outside interests.

Factors influencing community participation in mangroves restoration: A contingent valuation analysis

Background

This paper analyzes the willingness of a household to participate and pay for the benefits of a mangrove restoration program in the West Coast of India. In the second half of the twentieth century, this region has been threatened by shrimp cultivation, industrial development and hydroelectric projects, which overall made mangroves recede substantially.
