Among multiple slippage effects potentially generated in voluntary land retirement programs, this study attempts to identify one unique source of slippage. Specifically, I examine slippage caused by within-a-farm land conversion from uncultivated land to cropland. With the U.S. Agricultural Census farm-level longitudinal data on land use and enrollment in the Conservation Reserve Program (CRP), I find that an average partial-farm CRP participant converts 25% of noncropland to cropping activities as a consequence of CRP enrollment.

In the conditions of the Republic of Belarus there were examined different formulations of a notion and term of 'land use', there was presented its content taking into account modern conditions. There was shown the notion and content of intra-farm land use planning of agricultural organizations; its content updated with the issues on ecologization of land use planning. There was suggested an energy approach to the economic estimation of taken project decisions made in land use planning.

Livestock-water productivity (LWP) refers to a set of innovations that could contribute towards reducing the amount of water needed per unit of output generated. But what does it take to get these ideas adopted by livestock keepers in crop-livestock systems? In this paper, we treat LWP as an innovation, and consider in what ways it may be introduced and/or developed among the crop-livestock agricultural systems by drawing on successful examples of change.

In the conditions of the Republic of Belarus there was formulated a term of intra-farm organization of the territory of an agricultural enterprise. There was examined its content, role and meaning in the organization of agricultural production. On-farm organization of a territory of an agricultural enterprise represents a regularization of allocation of a complex of interrelated and interdependent sustainable elements of a territory which included natural and anthropogenic objects. There were presented the parameters, which characterized intra-farm organization of the territory.

AIM: Improving our understanding of the drivers of forest fragmentation is fundamental to mitigating the consequences of anthropogenic fragmentation for biodiversity. Moreover, the impacts of fragmentation on biodiversity depend on the spatial scale at which fragmentation occurs. Therefore, understanding how the effect of land use on fragmentation patterns varies across scales is critical to ensure that fragmentation is managed at scales relevant to the ecology of target species or to land management.

We used data available from the literature and measurements from Baltimore, Maryland, to (i) assess inter-city variability of soil organic carbon (SOC) pools (1-m depth) of six cities (Atlanta, Baltimore, Boston, Chicago, Oakland, and Syracuse); (ii) calculate the net effect of urban land-use conversion on SOC pools for the same cities; (iii) use the National Land Cover Database to extrapolate total SOC pools for each of the lower 48 U.S. states; and (iv) compare these totals with aboveground totals of carbon storage by trees.

There is a strong need for accurate and spatially referenced information regarding policy making and model linkage. This need has been expressed by land users, and policy and decision makers in order to estimate both spatially and locally the impacts of European policy (like the Common Agricultural Policy) and/or global changes on farm-groups. These entities are defined according to variables such as altitude, economic size and type of farming (referring to land uses).

We quantified potential biases associated with lakes monitored using non-probability based sampling by six state agencies in the USA (Michigan, Wisconsin, Iowa, Ohio, Maine, and New Hampshire). To identify biases, we compared state-monitored lakes to a census population of lakes derived from the National Hydrography Dataset. We then estimated the probability of lakes being sampled using generalized linear mixed models.

This paper presents findings of a land-use and land-cover (LULC) change mapping exercise conducted in Freetown, Sierra Leone. Nine LULC classes were mapped from multi-temporal Landsat data of 1974, 1986 and 2000. Special attention was given to the growth or otherwise of agricultural land in relation to other LULC classes. Conversion of one land-use/-cover type to the other was identified, and its effects discussed. Major conversions occurred between agricultural lands, grasslands, evergreen forest, built-up areas and barren land.

Two-thirds of the total area of Taiwan is mountainous terrain, which is the main groundwater recharge source of the plains region. This study assesses groundwater recharge and exploitative potential zone in the central division of the mountain areas of Taiwan (the middle reaches of the Jhuoshuei River Basin). Basic information from remote sensing and a satellite phantom is collected to set up the basic data maps using elevation, Formosa-II images, the Normalized Difference Vegetation Index, drainage distribution, slope, aspect ratio, lineament distribution, and land cover.
