| Households in rural India are highly dependent on firewood as their main source of energy, partly because non-biofuels tend to be expensive. The prevailing view is therefore that, when faced with shortages of firewood in the village commons, such households, and especially the women in them, have to spend more and more time searching for firewood and eventually settle for poorer-quality biomass such as twigs, branches and dry leaves. Using data from a random sample of rural households in the Indian state of Madhya Pradesh, we come to very different conclusions, however. We find that households in villages with degraded forests do not spend longer hours searching for firewood, but instead switch to either using firewood from private trees or to using... |

| Recreational hunting has been an attractive enterprise for some ranchers who are interested in supplementing their income from cattle. Ranchland attributes-such as parcel size, tree cover, and proximity to urban centers-are expected to influence hunters’ preferences and, thus, hunting lease payments. We estimated the effects of these attributes on hunting revenues using a hedonic model. The results reveal that trees and vegetation cover on ranchlands have a positive impact on hunting revenues, indicating opportunities for silvopasture practices. Those ranchers in Florida who maintain about 22% trees and other vegetation cover receive $16.15 acre per year from hunting leases, but doubling the cover would generate only an additional $3.20 per acre per... |

| Shade-grown coffee provides a livelihood to many farmers, protects biodiversity, and creates environmental services. Many shade-coffee farmers have abandoned production in recent years, however, in response to declines in international coffee prices. This paper builds a farmer decision model under price uncertainty and uses simulation analysis of that model to examine the likely impact of various policies on abandonment of shade-coffee plantations. Using information from coastal Oaxaca, Mexico, this paper examines the role of various constraints in abandonment decisions, reveals the importance of the timing of policies, and characterizes the current situation in the study region. |

| This paper maintains that the Forest Service (FS), as an institution, is in deep trouble. It argues that the FS today is an agency without a unique mission and without a supporting constituency. For the FS to be viable in the future it needs a distinct well-defined mission and a committed constituency. The distinct mission needs to be generally supported, or at least not opposed, by most of the American people. The constituency needs to be committed to the FS to the extent that it will provide major support in the Congress for FS budgets. The paper identifies some potential candidates for a mission for the National Forest System (NFS), e.g., as a biological reserve or as a provider of forest recreation. Another potential paradigm could be that of the... |

| According to FAO (2005) about 13 million hectares of the word’s forest are lost due to deforestation. Naoto (2006) found Africa to lead the list of countries with the highest rate of deforestation. This worrisome situation is further aggravated by the possible negative impacts of climate change due to an increase in the mean global temperature. Evidence supports that Africa is most likely to suffer the most the devastating impacts of natural calamities such as droughts and floods. This paper sought to evaluate the causes of deforestation in 27 Sub-Saharan African (SSA) countries. Our model uses annual data spanning from 1990 to 2004. Trade and urban population tend to be associated with a decline in deforestation. On the other hand, we found strong... |
