Farmers’ planting practices in Burkina Faso

Background

Improved Seed Supply for Agroforestry in African Countries (ISSAAC) is a Danish funded project led by ICRAF, FLD, and national seed centers in Burkina Faso, Malawi, and Uganda. This paper focuses on the project in Burkina Faso, whose overall objective is to improve farmer access to agroforestry seed.

Efecto de la zona de vida y la altitud en la mortalidad y adaptabilidad al primer año de especies forestales en la Cordillera Volcánica Central de Costa Rica

Español

Antecedentes

El entendimiento comprensivo de la restauración de bosques requiere de la comprensión del fenómeno de la mortalidad incluyendo su magnitud y ubicación espacial. En Costa Rica, no existe suficiente información capturando los efectos de climas pluviales sobre la mortalidad de especies forestales, especialmente en zonas altas.

Carbon sequestration versus bioenergy: A case study from South India exploring the relative land-use efficiency of two options for climate change mitigation

background

This study explores avenues to meet increased rural electricity demand with carbon emissions mitigation. The study compares the option of energy derived from gasification of biomass from forest plantations to energy derived from fossil fuels, with forest plantations used as a carbon sink.The case study uses power demand, land requirements, and management approaches for Hosahalli village, Karnataka, pop. 218.

Afforestation for Reclaiming Degraded Village Common Land: A Case Study

background

In India, population growth and agriculture put a strain on natural resources, often resulting in "wastelands" where the soil is no longer productive - often either affected by either salt or alkilinity. Using soil amendments to restore these lands to productivity can be cost-prohibitive for the small villages that own these lands. Afforestation is one possible method for restoring the health of these in a cost-effective and scalable way.

Timber Investment Returns for Selected Plantations and Native Forests in South America and the Southern United States

background

This study examines the value of timber investments in South America. Exotic Eucalyptus in the southern cone (Argentina + Chile) are the most profitable, with Internal Rate of Return of 13-23%, followed by exotic loblolly pine (Pinus taeda), whereas investments in the southeast USA is less profitable.

Effect of Exotic Tree Plantations and Site Management on Plant Diversity

Background

In this study of species richness, species behavior and stand parameters were analyzed under fast growing exotic tree plantations and compared with the characteristics of nearby secondary forest patches in Pointe-Noire and Loudima in Congo. The plantations were established in a grass-dominated vegetation of native savanna. The planted species investigated were mainly eucalypts hybrid (PF1), and secondarily Acacia auriculiformis and Pinus caribaea.

Expediting Reforestation in Tropical Forests Grasslands: Distance and Isolation from Seed Sources in Plantations

background

This study investigates the potential use of tree plantations to facilitate regeneration of indigenous trees in successionally arrested grassland. It focuses on how characteristics of the plantations and native species can determine the type of regeneration occurring in Kibale National Park, Uganda.

Restoration and Rehabilitation of Arid and Semiarid Mediterranean Ecosystems in North Africa and West Asia: A Review

background

This study systematically analyzes extensive literature on exclosures, afforestation, reafforestation, rehabilitation and other regeneration operations over several million hectares. It also includes 50 years of the author’s personal field experience in 17 of the 20 Mediterranean bioclimatic areas from the Atlantic Ocean to the Aral Sea.

Reforestation Strategies Amid Social Instability: Lessons from Afghanistan

Background

This study evaluates recent reforestation programs in Afghanistan in anticipation of larger scale programs needed to address watershed-scale degradation.

Research Goals & Methods

It surveys reforestation programs in rural upper watershed areas in Afghanistan in order to provide insight for similar problems in insecure regions elsewhere, especially where reforestation may help reverse degradation and assist with social stabilization efforts.
