Land tenure relations have both social and environmental implications, ranging from potential power issues to land stewardship. Drawing upon survey data of landowners collected in the Great Lakes Basin of the U.S., this study builds upon existing research by examining absentee landlords of agricultural land—a vastly understudied but growing category of landowners.

The aim of this article is to analyze the effectiveness of land-use policy in Mexico City in controlling the expansion of informal human settlements in peri-urban zones of high ecological value. It is argued that Mexico City's land-use policy has been reactive and internally inconsistent, failing to take informal settlements into account, has not offered the poor access to housing with adequate services and greater security in terms of land tenure, and lacks the necessary financial resources and institutional capabilities for providing solutions to these problems.

In article is devoted to problems of land relations in agriculture, which provides an analysis of the nature this dynamics in recent decades, assess the rationality of land use in the context of globalization and offers an innovative solution for forming a model of land relations in agriculture. The authors is a traced the cyclic processes in the history of the development of land and property relations, assesses the present stage of the next cycle and are historical parallels in socio-economic development.

Soil microbes play major agricultural functions such as the transformation of soil organic matter into plant fertilizers. The effects of agricultural practices on soil microbes at the scale of plots, from meters to hectare, are well documented. However, the impact at soil microscale, from micrometers to millimeters, is much less known. Therefore, we studied bacterial community density and diversity at microscale in crop soil under grassland, tillage, and no tillage.

The weedy Setaria species (giant, green, yellow, knotroot, and bristly foxtail) compose one of the worst weed groups interfering with world agriculture and in other disturbed and managed habitats. These species, together with their crop counterparts (foxtail millet, korali), form the foxtail species-group (spp.-gp). Five successive waves of Setaria spp. invasion from preagricultural times to the present have resulted in widespread infestation of the disturbed, arable, temperate regions of the earth. These invasions have resulted in considerable economic and environmental costs.

Agricultural production is based on environmental natural resources, that is soil, water, air and the whole landscape with its biodiversity. The using with resources of soil should therefore be balanced which would combine the tasks of farmhold utilizing from both economical, social and environmental protection point of views. Principles these be realized in special means by ecological agriculture as sustainable system of food production.

Most desertification research focuses on degradation assessments without putting sufficient emphasis on prevention and mitigation strategies, although the concept of sustainable land management (SLM) is increasingly being acknowledged. A variety of already applied conservation measures exist at the local level, but they are not adequately recognised, evaluated and shared, either by land users, technicians, researchers, or policy makers. Likewise, collaboration between research and implementation is often insufficient.

The environment and the natural resource base have been severely degraded in Alxa League, western Inner Mongolia, China, over the past half-century. This study reports surveys that reveal farmers' perceptions of environmental degradation and their adoption of improved management practices in this poor and remote desert region. Surveys were made in villages that had been engaged in a large environmental rehabilitation and management project [Alxa League environmental rehabilitation and management project (ALERMP)] and those that had not.

It is now widely accepted that agricultural intensification drives the decline of biodiversity and related ecosystem services like pollination. Conservation management, such as agri-environment schemes (AES), has been introduced to counteract these declines, but in Western European countries these tend to produce mixed biodiversity benefits. Not much is known about the effects of AES in Central and Eastern European countries. We evaluated the effect of reduced stocking rates (0.5cow/ha vs. >1cow/ha) on bees and insect-pollinated plants in semi-natural pastures in Hungary.
