It has been argued that the management of land, whether at the field, farm or regional scale, can benefit from computer-based land use system analysis. As a result, a large number of computer-based models and tools have been produced over the past decades with the aim of providing support to policy and management. Though there is still optimism about the potential of land use modelling to contribute to societal problem solving, a number of scholars perceive the impact as too limited.

Much is reported about the destruction of natural forests and the consequences for global warming, while on the other hand, exotic plantations in some regions struggle to gain public acceptance. The earth's population is projected to rise to around 9 billion by 2050, with a concomitant increase in demand for forest products. Inevitably, forests in general, and managed forest in particular, will be called on to provide an ever-increasing proportion of local supplies and the international wood trade.

Across vast areas of the world, human activity has degraded once fertile and productive land. Deforestation, overgrazing, continuous farming and poor irrigation practices have affected almost 2 billion hectares worldwide, threatening the health and livelihoods of over one billion people. In this edition of New Agriculturist, a collection of articles explores some of the approaches and policies that can help to successfully rehabilitate degraded land.

This study develops a dynamic multi-output model of farmers crop allocation decisions that allows estimation of both short-run and long-run adjustments to a wide array of economic incentives. The method can be used to inform decision makers on a number of issues including agricultural policy reform and environmental regulation. The model allows estimation of dynamic effects relating to price expectations adjustment, investment lags, and crop rotation constraints.

As a result of urban development farmland in many countries is under pressure. Reasons to preserve farmland are related to cultural heritage, food safety, open space, the environment, but also slowing and restricting development is a reason. To protect farmland countries use different land use policies. This paper will look specifically at two jurisdictions: The Netherlands and a particularly rich farming area in British Columbia, Canada. For these areas we will investigate how the institutions and laws present in these jurisdictions contribute to agricultural land preservation.

Fires have attracted interest and generated alarm since the early 1980s. This concern has been particularly evident in tropical forests of Southeast Asia and the Amazon, but disastrous fires in recent summers in Australia, Europe, and the United States have drawn worldwide attention.

Wolf Canis lupus dispersal, social structure and mortality have been extensively studied in natural and semi-natural areas of North America and northern Europe but have never been assessed in agricultural areas. From 1997 to 2004, 14 wolves (11 in a wolf-saturated area and three in a low-density area) were radio-collared with long-lasting transmitters in a Spanish agricultural area containing a high-human-population density, a dense network of roads and a shortage of wild ungulates. The wolves mainly feed on an overabundance of livestock carrion.

A dráguló olajár „felszínre hozta” a fosszilis energiahordozók környezetbarát energiahordozókkal való kiváltásának problémáját. Az olajkészletek korlátozottságamellett a bizonytalan kitermelés és a folyamatosan növekvő árak a bioüzemanyagokfelé irányítják a politikai döntéshozók és a befektetők figyelmét.

Latvia, United States of America
The current support policy is increasing gaps in land management intensity among different regions of the country. The support policy for agricultural and rural development does not deal with solutions for land abandonment or environmental objectives, because the abandonment is becoming a hidden, environmental policy and rural development process, which is more expensive for society. Some alternative approaches and principles for designing a new agricultural land policy for Latvia could decrease the policy costs and make land management more targeted and acceptable for society.
