Journal Articles & Books
Décembre, 2009
États-Unis d'Amérique

This paper reports the results of a study that explores the relationship between farm woodland owners' stated intentions for owning woodland, and the structure and composition of these woodlands in the states of Illinois, Indiana and Iowa in the upper Midwest of the United States. Data from two sample-based inventories conducted by the USDA Forest Service, Forest Inventory and Analysis (FIA) program were combined for this analysis--the FIA forest resources inventory and the National Woodland Owner Survey (NWOS).

Farmlink: promoting conservation buffers farmer-to-farmer

Journal Articles & Books
Décembre, 2009

Farmer-to-farmer outreach was used within a targeted watershed to promote the installation of conservation buffers. In this program called “FarmLink”, four farmers/landowners were employed part-time as “advisors” and trained by University of Nebraska-Lincoln Extension, Natural Resources Conservation Service, and Natural Resources District personnel. Topics included basic buffer design and benefits, availability of incentive programs, and sales techniques. These individuals then contacted their neighbors to explain the need for and benefits of buffers and other conservation practices.

Factors affecting farm operators' interest in incorporating riparian buffers and forest farming practices in northeast and southeast Missouri

Journal Articles & Books
Décembre, 2009

Interest in the incorporation of riparian buffers and forest farming were modeled following agricultural conservation and agroforestry adoption studies. Attitudes, individual characteristics, economic diversity of landowners' household portfolio, and physical and ecological conditions were explanatory variables in Logit regression models of interest. Habitus and field, the values and institutions of farm operators, were included in the framework.

Quantifying soil organic carbon in forage-based cow-calf congregation-grazing zone interface

Journal Articles & Books
Décembre, 2009

Recent concerns about global warming due to accumulations of atmospheric CO₂ have encouraged the achievement of better understanding of the roles of animal agriculture in mitigating CO₂ emissions. Grazing can accelerate and alter the timing of nutrient transfers, and increase the amount of nutrients cycled from plant to soil.

Sustainable agricultural development is a necessity for sustainable economic growth and social development in Africa. Sustainable agriculture largely depends on how effective natural and environmental resources are managed and utilized; it also depends on the security of continuous access to such resources. This research was aimed to look into trends in agricultural productivity, examine the persistence of the environmental insecurity, analyze the relationship between the two, and explore their links to the national development policies.
