A LOGIT ANALYSIS OF PARTICIPATION IN TENNESSEE'S FOREST STEWARDSHIP PROGRAM AgEcon
Bell, Caroline D.; Roberts, Roland K.; English, Burton C.; Park, William M..
This study determines the likely effect of cost-share incentives on participation in the Tennessee Forest Stewardship Program and identifies other factors that may contribute to participation. A random utility model is used to determine the probability that a landowner will choose to participate in the program. A binary choice model is specified to represent the dichotomous decision and a logit procedure is used to fit the model. Data are obtained from mail surveys of 4,000 randomly selected landowners. Results indicate that attitudes and knowledge of forestry programs may be more influential in a landowner's decision to participate than monetary incentives.

A Multisector Framework for Assessing Community-Based Forest Management: Lessons from Madagascar Ecology and Society
Raik, Daniela B; Cornell University; dbr23@cornell.edu; Decker, Daniel J; Cornell University; djd6@cornell.edu.
Community-based forest management has proliferated throughout Africa as national governments have decentralized the administration of public forestry. Community-based forestry has taken multiple forms, depending on the assortment of land-tenure systems, forest-use norms, wood demand, and social organization, among others factors. Nature, Wealth, and Power is an analytical framework that has been developed from experiences in natural resource management in Africa. In this paper, we amend the framework to People, Nature, Wealth, and Power (PNWP), and propose it as an analytical lens for community-based forest management initiatives. We use the PNWP framework to assess the responsiveness of contractual forest management in the Menabe region of Madagascar to...

Afforestation and Timber Management Compliance Strategies in Climate Policy. A Computable General Equilibrium Analysis AgEcon
Michetti, Melania; Nunes Rosa, Renato.
This paper analyzes the role of afforestation-reforestation and timber management activities, and their major and secondary economic effects in stabilizing climate during the first commitment period of the Kyoto Protocol. In particular, with a Computable General Equilibrium framework, the ICES model, it is inferred how forest carbon sequestration fits within the European domestic portfolio of a 2020-20 and 2020-30 climate stabilization policy. Afforestation and land use are accounted for by introducing their effects in the model. This is done by relying on carbon sequestration curves provided by Sohngen (2005), which describe the average annual cost of sequestration for selected world regions. Results show that afforestation and timber management could...

Analyse ausgewählter internationaler Studien und Dokumente in Hinblick auf Kosten und Potentiale der Minderung von Treibhausgasemissionen sowie des Aufbaus und der Erhaltung von C-Senken im deutschen Agrar- und Forstsektor AgEcon
Osterburg, Bernhard; Roder, Norbert; Elsasser, Peter; Dieter, Matthias; Krug, Joachim.
Zusammenfassung: In dieser Studie werden Dokumente der Europäischen Kommission zur künftigen Klimaschutzstrategie, eine Studie von McKinsey sowie ein UNFCCC-Papier in Hinblick auf Aussagen zu Klimaschutzmaßnahmen im Agrar- und Forstbereich untersucht. Die EU-Dokumente lassen einen steigenden politischen Handlungsbedarf für den Klimaschutz auch außerhalb des Treibhausgasemissions-Handelssystems (EU-ETS) erwarten. Die anderen beiden Dokumente geben Einschätzungen zu weltweiten Klimaschutzpotentialen wieder, und die Ergebnisse sind nur sehr eingeschränkt auf Deutschland anwendbar. In Kapitel 3 werden erste Ergebnisse einer Literaturanalyse zu Potentialen und Kosten von Maßnahmen im Agrarbereich dargestellt. Die Literaturanalyse ergab keine umfassenden, für...

Australian tree species selection in China AgEcon
McKenney, Daniel W..
The Australian Centre for International Agricultural Research (ACIAR), through collaborative projects with the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia, and the Chinese Academy of Forestry (CAF), has been involved in tree species selection trials in southern China since 1984. The trials were aimed at identifying fast-growing species of Eucalyptus, Acacia and Casuarina. The Chinese have been planting Australian tree species for more than 100 years, but before the ACIAR project there had been little progress in determining which species and provenances would be best for the local climate and soils. This paper presents an assessment of the economic impact of research undertaken under two ACIAR-supported projects....

Biodiversity Planning Support Programme Integration of Biodiversity into National Forest Planning Programmes: The Case of Gabon OceanDocs
Nasi, R..
With a very high forest cover (over 80%) and low population density (below 5 inhbts/km2), Gabon is still a forest biodiversity rich country. Gabon's forests are amongst the richest in Africa in terms of botanical diversity and endemism for example, 22% of plants described in the Flora of Gabon are endemic and the forests of Gabon have more plant species (estimated at 8000 species) than all of the forests of West Africa combined. The fauna is also rich, estimated at more than 190 mammal species, including at least 20 species of monkeys, more than 600 species of birds, 70 species of reptiles and 100 species of amphibians. About 35,000 gorillas and 64,000 chimpanzees dwell in Gabon forests and elephants number between 60,000 and 74,000 individuals. The...

Biotechnology's Potential Contribution to Global Wood Supply and Forest Conservation AgEcon
Sedjo, Roger A..
Over the past 30 years, industrial plantation forests have become a major supplier of industrial wood. There are several reasons for this, including the improved economics of planted forests due to biotechnological innovations, the increases in natural forest wood costs due to increasing inaccessibility, and rising wood costs from natural forests due to new environmental restrictions related to logging. Forestry today is on the threshold of the widespread introduction of biotechnology into its operational practices. In many cases, the biotechnology likely to be introduced is simply an extension of that being utilized in agriculture, such as herbicide-tolerant genes. However, biotechnology in forestry also is developing applications unique to forestry,...

Can Permanence Be Insured? Consideration of Some Technical and Practical Issues of Insuring Carbon Credits from Afforestation and Reforestation AgEcon
Wong, Jenny L.P.; Dutschke, Michael.
Greenhouse gas (GHG) removals by afforestation and reforestation project activities under the Kyoto Protocol's Clean Development Mechanism (CDM) are vulnerable to a variety of risks and uncertainties, resulting in the partial or total reversal of such removals. Hence, GHG removals from these sink activities are considered to be of temporary nature and non-permanent. Specific modalities related to non-permanence will need to be developed in order to include afforestation and reforestation project activities under the CDM and for a decision on modalities to be reached at COP 9 in December 2003. Two main options on how to address non-permanence have been proposed, these being temporary credits and insurance of emission reduction credits. This paper discusses...

Carbon Leakage with Forestation Policies AgEcon
de Gorter, Harry; Drabik, Dusan; Just, David R..
This paper analyzes carbon leakage due to reduced emissions from deforestation (RED). We find that leakage with RED is good because the policy induces afforestation that contributes to a further carbon sequestration. By ignoring the domestic component of carbon leakage, the literature can either overestimate or underestimate leakage, depending on the magnitudes of the numerator and the denominator of the leakage formulas. Unlike the literature, we include the land and agricultural markets in the analysis of carbon leakage with forestation policies. In this model, carbon leakage depends on: (1) supply and demand elasticities of timber production and consumption, respectively in the country introducing a RED policy (Home country) and in the rest of the...

Coastal Ecosystems OceanDocs
The coastal forest communities of Kenya exist mainly as isolated blocks which show high levels of species endemism and comprise a total of about 83,800ha in a narrow belt which extends inland for about 30km. The forests are characterized by dense or moderately dense stands of tall trees, species of the genera Sterculia, Chlorophora and Memecylon. The drier woodlands include stands of Cynometra, Manilkara and Afzelia. Centuries of human occupation have reduced the forest element which was originally more extensive. Mangrove swamps occur in tidal estuaries and lagoons while coconut palms are common above high tide. A complex of many bush types occur in the high bush area. Scattered baobab trees present a striking appearance while the prevalence of mango...
