A hazai zöldségtermelés megújítása AgEcon
Hodossi, Sandor; Dudas, Laszlo; Fari, Miklos Gabor.
Az éghajlatváltozás hatásai a minőségi termelés követelményei, a rentábilis termelés igénye, a termeléstechnológiai elemek megújításának, korszerűsítésének szükségessége egyaránt sürgetik a fenti követelményeket szem előtt tartó, annak megfelelni akaró módszert, a szabadföldi intenzív termelést, melynek legfontosabb elemei: az időszakos talaj-, növény- és légtértakarás, a víztakarékos öntözési módok alkalmazása és a retardált műtrágya használata. Az időszakos talaj-, növény- és légtértakarással a szedési időszak meghosszabbítható, és egyúttal javítható a talaj vízgazdálkodása, valamint visszaszorítható a gyomosodás. A mikroöntözés alkalmazásával, azonos vízmennyiséggel kétszer akkora terület öntözhető. Retardált (fékezett lebomlású) műtrágyák...

Climate Policy Design under Uncertainty AgEcon
Pizer, William A..
The uncertainty surrounding both costs and benefits associated with global climate change mitigation creates enormous hurdles for scientists, stakeholders, and decision-makers. A key issue is how policy choices balance uncertainty about costs and benefits. This balance arises in terms of the time path of mitigation efforts as well as whether those efforts, by design, focus on effort or outcome. This paper considers two choices-price versus quantity controls and absolute versus relative/intensity emissions limits-demonstrating that price controls and intensity emissions limits favor certainty about cost over climate benefits and future emissions reductions. The paper then argues that in the near term, this favoritism is desired.

Factors influencing the intensity of market participation by smallholder farmers: A case study of rural and peri-urban areas of Kenya AgEcon
Omiti, John M.; Otieno, David Jakinda; Nyanamba, Timothy O.; McCullough, Ellen B..
Participation in commercial agriculture holds considerable potential for unlocking suitable opportunity sets necessary for providing better incomes and sustainable livelihoods for small-scale farmers. This study examined factors that influence the intensity of market participation among smallholder farmers in Kenya. Data was obtained through a rapid rural appraisal and a household survey. A truncated regression model was applied in the analysis. Results showed that farmers in peri-urban areas sold higher proportions of their output than those in rural areas. Distance from farm to point of sale is a major constraint to the intensity of market participation. Better output price and market information are key incentives for increased sales. These findings...

The Case for Intensity Targets AgEcon
Pizer, William A..
While the rest of the world has pursued absolute emissions limits for greenhouse gases, the Bush administration has proposed an alternative policy formulation based, among other things, on reducing emissions intensity-that is, emissions per dollar of real gross domestic product. Critics of this formulation have denounced the general idea of an intensity-based emissions target, along with its voluntary nature and weak targets. This raises the question of whether intensity-based emissions limits, distinct from the other features of the Bush initiative, offer a useful alternative to absolute emissions limits. This paper makes the case that they do, based on how emissions targets are framed. The argument draws on four key observations: greenhouse gas emissions...
