Das HWWI hat im Auftrag des Projektentwicklers Peper & Söhne eine Studie zur möglichen Nutzung des ehemaligen Güterbahnhofsgeländes in Bremen erstellt. Dabei untersucht das HWWI neben dem wirtschaftlichen Umfeld auch, welche Chancen und Potenziale sich aus Megatrends wie der Digitalisierung,...

The Conservation Reserve Program (CRP) is arguably the world's largest conservation program on private lands, with $1.8 billion paid to farmers in 2017 for practices on 23.4 million acres. Existing theory and literature suggest that a modified auction structure could make CRP more...

Now over 25 years old, as of June 2012 the Conservation Reserve Program (CRP) removes over 29 million acres of environmentally sensitive farmland from crop production under 10- to 15-year contracts. Over time, the program's size and goals have changed, from its early emphasis on limiting crop...

2016 gab es nach der Flächennutzungskartierung des RVR 14.474 Hektar 'nicht genutzte Flächen' (Brachflächen/Konversionsflächen) im RVR-Gebiet. Dies entspricht in etwa einer Fläche von 13.400 Fußball-Spielfeldern. Die höchsten Anteile weisen 'nicht genutzte Flächen' der Typen 'Sonstige'...

CultNature ist als ein interaktives Entwicklungs- und Gestaltungsprojekt angelegt, bei dem es vor allem da-rum geht: Evidenzbasiertes Handlungswissen über urbane Flächenpotentiale und ihre Nutzung im Bereich erneuerbarer Energien, über die damit verbundenen Finanzierungsfragen und...

By improving wildlife habitat and air and water quality, CRP has significantly increased the number and variety of wildlife, attracting bird watchers, hunters, anglers, and other outdoor recreation enthusiasts, who then spend money in rural areas. In 2004, ERS research confirmed that the CRP’s...

Reductions in maximum Conservation Reserve Program (CRP) acres mandated by the 2008 Farm Act, along with relatively high agricultural commodity prices, could lead to reduced overall environmental benefits and higher CRP costs. ERS is analyzing alternative enrollment policies and practices that...

This report considers how increased commodity prices might influence enrollment in and benefits from the Conservation Reserve Program (CRP) using two complementary models: a likely-to-bid model that uses National Resources Inventory data to simulate offers to the general signup portion of the...

This report estimates the impact that high levels of enrollment in the Conservation Reserve Program (CRP) have had on economic trends in rural counties since the program's inception in 1985 until today. The results of a growth model and quasi-experimental control group analysis indicate no...

Die vorliegende Arbeit mit dem Titel Anreizsysteme zum Flächenrecycling für mindergenutzte bzw. brachgefallene Flächen mit gewerblicher Vornutzung basiert auf einer empirischen Datenerhebung in 10 Kommunen in Baden-Württemberg mit anschließender Befragung der an einer Brachenrevitalisierung...

Russia is a major player in the global wheat market, but extensive unused land resources and large yield gaps suggest that wheat production can be substantially increased. We combined time series of cultivated cropland, abandoned cropland and yield gap estimates to assess the potential...

Small farmers in many tropical developing countries practice swidden agriculture. A key aspect of swidden agriculture is the time period during which the land is left fallow. This paper uses a new ecological-economic approach to study the fallow period and to determine the optimal length of this...

Fazit der Leopoldina-Studie: Ausbau der Bioenergie auf landwirtschaftlichen Nutzflächen nicht fortführen. Flächenkonkurrenz: Bis zum Jahr 2030 werden ca. 500 Mio. ha zusätzliche Agrarfläche für die menschliche Ernährung benötigt. Flächenverbrauch und Bauprojekte auf 'Grüner Wiese':...

Dargestellt werden die Ergebnisse einer Befragung zu den ersten Einschätzungen des CultNature-Konzepts durch die für das Projekt relevanten Akteure. Ziel ist die Abschätzung des mit dem Projekt verbundenen Erwartungshorizontes. Das Projekt wurde von den relevanten Akteuren in vielen Punkten...

Benefit transfer is a quick and inexpensive alternative to conducting an original study to determine economic value. Although this practice is attractive, it can result in biased welfare estimates. This paper proposes a method of calibrating benefit transfers in order to reduce this bias. An...

Set-asides and subsidies are used extensively in government procurement and natural resource sales. We analyze these policies in an empirical model of U.S. Forest Service timber auctions. The model fits the data well both within the sample of unrestricted sales where we estimate the model, and...

Socio-economic and institutional changes may accelerate land-use and land-cover change. Our goal was to explore the determinants of agricultural land abandonment within one agro-climatic and economic region of post-Soviet European Russia during the first decade of transition from a state-command...

Given that the Conservation Reserve Program (CRP) costs taxpayers $2 billion per year and remains the largest conservation program in U.S. history, Roberts and Bucholtz are to be commended for revisiting the slippage issue. However, their central point that regional variation in CRP acreage is...

The Conservation Reserve Program (CRP) pays farmers about $2 billion per year to retire cropland under ten- to fifteen-year contracts. Recent research by Wu found that slippage - an unintended stimulus of new plantings - offsets some of CRP's environmental benefits. Wu does not account for the...

Each year, billions of dollars of public funds are expended to purchase conservation easements on farmland. One unintended impact of these programs is that they may bring non-cropland into crop production. Such a slippage effect can be caused by increased output prices and by substitution...

The growth in conservation programs has created a need for modeling frameworks capable of measuring microlevel behavioral responses and macrolevel landscape changes. This paper presents an empirical model that predicts farmers' production practices and the resulting levels of agricultural...
