Properties, best management practices and conservation of terraced soils in Southern Europe (from Mediterranean areas to the Alps): A review

Europa

Terrace soils are distinctive features of the agricultural landscape in Europe. Due to their historical and aesthetic significance, they are a resource for agriculture and tourism: however they are also a challenge for land conservation and management. Nevertheless, the fundamental role of terrace soils for agricultural quality and natural hazard prevention has not been fully investigated. In the past, terraced slopes became ideal sites for human settlement and agricultural activities.

Negative Off-Site Impacts of Ecological Restoration: Understanding and Addressing the Conflict

Journal Articles & Books
Dezembro, 2008

Ecological restoration is a key component of biological conservation. Nevertheless, unlike protection of existing areas, restoration changes existing land use and can therefore be more controversial. Some restoration projects negatively affect surrounding landowners, creating social constraints to restoration success. Just as negative off-site impacts (i.e., negative externalities) flow from industrial areas to natural areas, restoration projects can generate negative externalities for commercial land uses, such as agriculture.

The advent of grid electrification in the Sandveld region of South Africa in the 1980s increased the utilisation of groundwater resources for commercial irrigation purposes. In the wake of the consequent increased pressure on the resource, it behooves landowners to use water more productively and responsibly. This paper calculated the marginal product value (MPV) of irrigation water for potatoes and vine production in this region to assess and to allow the comparison of the productivity of irrigation water with other commodities and regions.

Using policy to promote participatory planning: an examination of Minnesota's Lake Improvement Districts from the citizen perspective

Journal Articles & Books
Dezembro, 2012

Increased development around Minnesota's lakes and their respective watersheds has degraded lake health in counties surrounding the St. Paul and Minneapolis metro areas. Confronted with the implications of degraded lakes, such as loss of property values and declining recreational experiences, lakefront landowners, and those using the lake for recreation, are increasingly looking for meaningful ways to engage in activities to improve lake water quality.

arithmetic method to determine the most suitable planting dates for vegetables

Arábia Saudita

Optimum crop yield is greatly affected by proper planting and sowing times. The objective of this research was to develop an algorithm that uses the heat unit concept to determine the most suitable planting times for vegetable crops. The developed algorithm was programmed in a database environment with sample climatic data for the Kingdom of Saudi Arabia. The model was tested by validation (comparison to experts’ estimations), verification (statistical comparison to formal published data), and evaluation (by professionals, landowners, and farmers).

Red deer hunting—commercializing versus availability

Many deer populations in Europe and North America have increased in abundance over the last decades. The increasing populations potentially entail both ecological and economic challenges and opportunities, but in practice we still know little about the extent to which these opportunities are being exploited in different management systems. The Norwegian red deer population has increased in density and expanded rapidly since the 1950s. Traditionally, red deer hunting has been undertaken by the local landowner and his relatives and friends.

Impacts of Southern Oak Seedling Survival on Investment Returns in Mississippi

Journal Articles & Books
Dezembro, 2003

Increasingly, landowners are establishing hardwood plantations to satisfy their land management goals. Unfortunately, little is known about how competition control affects initial seedling survival and subsequent investment returns for hardwood plantations. This study examines five alternative competition control regimes for southern oak establishment. The regimes include no site preparation, disking only, sub-soiling with rotary mowing, herbicides only, and herbicides with rotary mowing and sub-soiling.

Understanding Loggers' Perceptions

Dezembro, 2003

Loggers play a critical role in managing forest resources. This study focused on understanding loggers' attitudes-information that we believe would be useful for improving communications and ultimately improving forest practices. Through interviews and a mail survey, four themes emerged, providing insight into loggers' attitudes: (1) Pennsylvania loggers are proud of their industry, (2) Public pressure is affecting the logging industry, (3) Loggers are concerned about the future, and (4) Loggers, foresters, and landowners need to improve their communications.

Best management practices and timber harvesting: the role of social networks in shaping landowner decisions

The influence of social others in private landowner decision-making has received limited attention despite growing support for peer-to-peer learning and landowner cooperative behavior. We applied social network analysis (SNA), a relatively novel methodology in the context of private forestry, to evaluate the influence of landowners' social networks on their forestry management decisions and as related to current policy arrangements in Wisconsin, USA.

Characteristics of Logging Businesses that Harvest Biomass for Energy Production

Journal Articles & Books
Dezembro, 2014

Utilization of biomass from logging residues for renewable energy production depends on forest harvesting businesses. As biomass markets emerge, businesses will need to adapt to meet operational requirements. Logging businesses that supplied biomass for energy production in Virginia were surveyed regarding operations and attitudes. Results show that businesses across a broad range of total production levels (150 to 6250 tons/wk) harvested biomass and roundwood using integrated harvesting operations with whole tree chippers. Businesses had produced biomass an average of 6.8 years.
