| Successful agricultural development has resulted in substantial alleviation of poverty and food security in Asia and Latin America since the 1960s. Much of this success can be attributed to the introduction of high-yielding varieties of crops, especially wheat and rice, which have addressed the constraints faced by farmers using traditional varieties. In Sub-Saharan Africa (SSA), however, productivity levels have remained stagnant despite the introduction of new crop germplasm. In recent years, scientists have recognized that low soil fertility is the primary constraint blocking agricultural development in SSA. Major findings from this study may be summed up in five key points. Declining fertility and SOM in SSA are a result primarily of... |

| In this study we attempt to understand the relationship between regional growth in population, employment, and per capita income, and farmland development in Maryland, Pennsylvania, and West Virginia. A spatial simultaneous equations model is estimated using county-level data. Results indicate that while county income growth and agricultural land value increases in neighboring counties increase the rate of farmland loss, growth in county agricultural land values, increases in agricultural land density in neighboring counties, and increases in agricultural income per farm reduce farmland losses. Farmland protection policies were not significant in reducing agricultural land development. This approach, focused on regional growth, provides insight into... |

| This paper uses hedonic analysis to examine the impact of small dam removal on property values in South-central Wiscosin. Data on residential property sales were obtained for three categories of sites: those where a dam is intact, those where a dam was recently removed, and those where the stream has been free-flowing for at least 20 years. The primary conclusions that emerge from the data are that residential property located in the vicinity of a free-flowing stream is more valuable than identical property in the vicinity of a small impoundment, and that shoreline frontage along small impoundments confers no increase in residential property value compared to frontage along free-flowing streams. |

| Beginning in January 1991, the U.S. Agency for International Development funded a series of studies on land, employment, and financial markets in the peri-urban areas of Maputo. Beginning in September 1991, a land-market survey involving 121 households and 162 plots of land was administered in two peri-urban green zones of Maputo-districts 4 and 6. Households were queried about their land-settlement histories, mode of land acquisition, terms and conditions of transfer, land rights, size of holdings, perceptions of tenure security, land-use practices, commercial input use, hired labor, agricultural sales and revenues, nonfarm employment and earnings, and general demographic characteristics. The present study reports findings from the land-market survey... |

| While theory strongly suggests that restricting development rights should reduce land prices, empirical evidence of this effect has been notoriously hard to obtain. Indeed, largely based on this difficulty a Congressional committee has recently recommended that tax benefits for such restrictions be severely curtailed. We collect data on 131 land transactions in South Central Wisconsin, including 19 cases of developmentrestricted parcels. When we use the whole sample to estimate the impact of conservation easements we replicate the results of Nickerson and Lynch (2001), finding a negative but statistically insignificant effect. However we then show that when the sample is appropriately restricted to a more homogenous group of land parcels, our ability to... |

| Many communities are experiencing the negative effects associated with not sustaining a sufficient level of tree canopy coverage. Tree canopy plays a crucial role in the environment, providing benefits such as clean water and air, erosion prevention, climate control, and sustained ecological resources and native species habitat. Additionally, tree canopy plays an economic role by increasing housing values, alleviating expenditures related to erosion destruction, decreasing spending on sewer standards, increasing energy efficiency, and reducing medical costs related to health issues, such as asthma, that are associated with environmental degradation. To study how local government policies may be related to changes in tree canopy, an empirical study was... |

| Economic impacts often are cited as justification both for and against changes in grazing policy on public lands. A recent study conducted in Owyhee County, Idaho, illustrates a process to gather ranch-level economic information, develop economic models for different ranching systems, and use the models to estimate economic impacts of grazing policy changes. Ranch-level models were developed from producer panels and interviews within the county. Costs and returns, livestock production information, dependency on public lands, and other factors relative to ranch-level economics were gathered in four meetings with livestock producers and other interested parties. Results indicate that, as dependency on federal lands rise, both costs and returns fall.... |

| This study investigates the micro-determinants of land use change using community, household and plot histories, an ethnographic method that constructs panel data from systematic oral recalls. A 20-year historical timeline (1975-1995) is constructed for the village of La Lima in central Honduras, based on a random sample of 97 plots. Changes in land use are examined using transition analysis and multinomial logit analysis. Transition analysis shows that land use transitions were relatively infrequent in areas under extensive cultivation, but more so in areas of intensive cultivation; and that most changes favored intensification. Econometric analysis suggests that land use intensification was influenced by plot level variables (especially altitude, slope,... |

| This staff paper provides (1) a summary of the proposed bill regarding the annual conservation and land preservation tax concept, (2) observations and a preliminary assessment of the impacts, and (3) an outline of potential issues, considerations, and related alternative concepts that policymakers, interest groups and citizens may wish to consider during the course of debate on the proposal. Ideas and concepts discussed in this staff paper should not be considered recommendation, but rather fodder consisting of alternative ideas to fully inform and assist policymakers in making informed choices and reducing unintended consequences. |

| Up to 60% of potable water supplied to Perth in Western Australia is extracted from the Gnangara mound. Many of the urban wetlands above the Mound are groundwater-dependent. Excessive groundwater extraction and climate change have resulted in a decline in water levels in the wetlands. This study estimates the value of urban wetlands in three local government districts in the Perth metropolitan region using the hedonic property price approach. Preliminary results found that proximity to wetlands influences the sales prices of properties. The marginal implicit price of reducing the distance to the nearest wetland by 1 metre, evaluated at the mean sales value, is AU$463. If there is more than one wetland within 1.5 kilometres of a property, the second wetland... |

| In a two-period model, economists such as K.J. Arrow, A.C. Fisher, and C. Henry, have shown that when development is both indivisible and irreversible, a developer who ignores the possibility of obtaining new information about the outcome of such development will invariably underestimate the benefits of preservation and hence favor development. In this note, I extend the AFH analysis in two directions. I model the land development problem in a dynamic framework, explicitly specifying an information production function. In such a setting, I then ask and answer the question concerning when development should take place. Forthcoming in Journal of Environmental Management |

| Farmland often contributes scenic quality and cultural heritage to a region; however, these factors are challenging to incorporate into standard farmland valuation schemes because of their qualitative nature. This research develops a method for enhancing the Land Evaluation and Site Assessment (LESA) model to incorporate scenic quality and cultural heritage elements into the rating scheme. Data on the scenic quality and cultural heritage values of the community was gathered via a participatory geographic information system (PGIS) exercise and combined with traditional LESA factors to develop a GIS-linked enhanced LESA model. This method provides a holistic valuation of farmland characteristics and directly incorporates community values. When a LESA model... |
