A bioüzemanyag-gyártás nemzetközi összefüggései AgEcon
Popp, Jozsef.
A dráguló olajár „felszínre hozta” a fosszilis energiahordozók környezetbarát energiahordozókkal való kiváltásának problémáját. Az olajkészletek korlátozottsága mellett a bizonytalan kitermelés és a folyamatosan növekvő árak a bioüzemanyagok felé irányítják a politikai döntéshozók és a befektetők figyelmét. Az olajimportőr országoknak a bioüzemanyag-gyártás nyersanyagainak hazai termelése lehetővé teszi importköltségeik visszafogását, az üvegházhatást okozó gázok kibocsátásának csökkentését, valamint a mezőgazdasági termelők jövedelem-színvonalának javítását. A bioüzemanyagok elterjedése ugyanakkor enyhíti a kapacitása határán dolgozó olajfinomító ipar üzemanyag-ellátási terheit is, ami jelentős mértékben hozzájárul(t) az üzemanyagárak emelkedéséhez. Ma...

Adoption of Maize Production Technologies in the Coastal Lowlands of Kenya AgEcon
Wekesa, E.; Mwangi, Wilfred; Verkuijl, Hugo; Danda, Milton Kengo; De Groote, Hugo.
Maize is the major food crop grown in the coastal region of Kenya and constitutes a major component of the diet of the population in the region. However, average yields are far below the potential for the region and low production levels create serious food deficits. Over the years, new technologies have been introduced but adoption has remained low, especially for fertilizer. This paper examined current maize-farming practices and technological and socioeconomic factors that influenced adoption in the Kilifi and Kwale Districts of the Coast Province, that together account for half of maize production in the region. The study found low adoption levels for improved maize varieties and technology, especially fertilizer, among farmers in the area. Farmers...

ALBERTA AGRICULTURE AND FOOD TRADE: RECENT TRENDS AgEcon
Rosario, Joe A..
Exports have been an integral and essential feature of the agriculture and food industry in Alberta. This is a product of the province’s relatively low population and consumption base on the demand side juxtaposed with a large resource base of prime agriculture land for crop production and an abundance of range and pasture for grazing and forage for raising livestock on the supply side. A host of factors influence the disposition of surplus production or exports including global supply/demand balances, relative cost/price relations, structural changes through farm consolidation and scale economies, market access, exchange rates, sanitary and phyto‐sanitary standards and regulations, disease and pest related issues. The inherent nature of agriculture means...

Assessment of the effectiveness of maize seed assistance to vulnerable farm households in Zimbabwe AgEcon
Langyintuo, Augustine S.; Setimela, Peter S..
The publication describes outcomes of a study to assess the effectiveness of a large-scale crop seed relief effort in Zimbabwe during 2003-07. Aims of the effort, which was supported by the British Department for International Development (DfID) and coordinated by the Food and Agricultural Organization (FAO) regional office in Harare, included broader diffusion of open-pollinated maize varieties (OPVs), as opposed to hybrids. Based on the findings of the study, the authors recommend that, to increase benefits to vulnerable groups, participants in such efforts should effectively disseminate information on selecting and recycling seed, supported by training and field demonstrations, and should target relatively well-endowed farmers initially. Recommendations...

Balance between food production, biodiversity and ecosystem services in Brazil: a challenge and an opportunity Biota Neotropica
Martinelli,Luiz Antonio; Filoso,Solange.
Brazil has a unique position in the world. It is one of the few countries that can be one of the most important producers of food, fiber and biofuel and at the same time maintain its mega biodiversity endowment and vital ecosystems services properly running. This is a challenge that only can be achieved by recognizing the importance of agribusiness sector to the Brazilian economy, but also that ecosystems have limits and we should not endless expand agriculture in the name of "development". Ecosystem services have to be recognized also as a "development" to be kept for the next generations. Agriculture only exists where ecosystems are able to maintain its basic functioning. Therefore, a well preserved nature it is the most precious asset of agriculture.

CAMBIO DE PARADIGMA, PRODUCCIÓN DE ENERGÍA O DE ALIMENTOS: EL CASO DE PUERTO RICO AgEcon
Colon Guasp, Wilfredo.
The amount of energy and food consumed in Puerto Rico is more indicative of a developed nation than one than is underdeveloped. All the energy consumed in Puerto Rico is from fossil fuels, while the agricultural sector marginally provides the needs of the consumer. In addition, the animal production sectors rely exclusively on imported feedstock for the preparation of feeds. There is a potential to develop an ethanol industry based initially on sugarcane, as the main feedstock and then turn to biomass from energy cane and or organic solid waste in the future. In order to move to the second generation of ethanol production, the cellulosic ethanol industry has to become economically viable. A limiting factor in the use of sugarcane is that only 40,000 ha are...

Cost of GMO-related co-existence and traceability systems in food production in Germany AgEcon
Menrad, Klaus; Gabriel, Andreas; Zapilko, Marina.
In contrast to the increasing use of GM plants in world-wide agriculture, the acceptance of GM food is still low in the European Union (EU). In order to ensure freedom of choice for consumers and users of GM and non-GM products, GM food and feed products have to be labeled in case a tolerance threshold of 0.9 % is exceeded for EU authorized GMOs. This paper aims to quantify the cost of traceability and co-existence systems for GM food from the seed to the food level for sugar, wheat starch and rapeseed oil for human consumption in Germany respecting the 0.9 % threshold for labelling of GM food. The cost calculation for traceability and co-existence measures follows the principle of aggregating all incurred cost on the different levels of the value chain...

Disponibilidade nutricional e calórica dos alimentos produzidos em Rio Claro, RJ: uma contribuição à análise da segurança alimentar e nutricional do município. Infoteca-e
FIDALGO, E. C. C.; TURETTA, A. P. D.; PEDREIRA, B. da C. C. G..
A segurança alimentar existe quando todas as pessoas, em todos os momentos, têm acesso físico, social e econômico a alimentos suficientes, seguros e nutritivos que atendam às suas necessidades dietéticas e preferências alimentares para uma vida ativa e saudável. Tal conceito, estabelecido pela Organização das Nações Unidas para a Alimentação e a Agricultura, é multidimensional, baseado em quatro pilares fundamentais: disponibilidade de alimentos, acesso a alimentos, utilização de alimentos e estabilidade da oferta de alimentos. A disponibilidade do alimento, que significa a oferta de alimentos para toda a população, depende da produção, da importação (quando necessária) e de sistemas de armazenamento e distribuição. Considerando que a agricultura é a...

Economic and management issues involved in the adoption and maintenance of integrated crop-livestock systems MV&Z
Mendonça, Gabriela Geraldi; Augusto, Jeferson Garcia; Bonacim, Pedro Miele; Menegatto, Leonardo Sartori; Simili, Flávia Fernanda; Gameiro, Augusto Hauber.
Professionals involved in animal and plant production chains are currently confronted with a scenario of contradictions. There is a growing demand for food, on the other hand, social pressures question how food is produced. Within this context, integrated production systems could be an important strategy. Integrated crop-livestock systems (ICL) consists of the implementation of different systems for animal and agricultural production in the same area, planted concurrently, sequentially or in rotation. The most reported advantages of ICL systems are agronomic or productive benefits, which are the result of improved soil quality and better pest control. However, to implement ICL systems on large scale, representing an actual alternative for food production,...

Effects of Agricultural Greenhouse Gas Emission Mitigation Policies: The Role of International Trade AgEcon
Schneider, Uwe A.; Lee, Heng-Chi; McCarl, Bruce A.; Chen, Chi-Chung.
The Kyoto Protocol represents the first international agreement to reduce greenhouse gas emissions. Proposed mitigation efforts may involve the agricultural sector through such options as planting trees, crop and livestock management changes, and biofuels production. The combined use of these strategies could substantially reduce net emissions of carbon dioxide, methane, and nitrous oxide. However, countries where the Protocol imposes emissions caps have expressed concern about their competitiveness with countries that are not part of the Kyoto Protocol. In a free-trade arena, food production and exports in unregulated countries could increase and reduce market share for the producers in complying countries. We examine the effects of differential Protocol...
