A conservação de bacias e os desafios para a sustentabilidade da agricultura. Infoteca-e
FIGUEIREDO, R. de O.; GREEN, T. R..
Resumo: Esta publicação aborda a complexidade e os desafios para que se alcance a sustentabilidade no uso da terra, no tocante à conservação dos recursos hídricos e respectivas bacias hidrográficas. Trata da dinâmica de alterações nos processos biogeoquímicos e hidrológicos presentes nas bacias onde o ecossistema natural é modificado. Considera, também, as variações temporais e espaciais distintas, dependendo das características biofísicas e biogeoquímicas originais da bacia, ao lado do uso da terra presente. Os autores abordam como e porque a bacia hidrográfica deve ser considerada a unidade de estudo primordial nas análises ambientais que visam a conservação de recursos hídricos. São, assim, considerados os processos naturais, o manejo agropecuário, a...

A földbirtok-politika lehetséges irányai (Az eddigi vita összefoglalása) AgEcon
Kapronczai, Istvan.
A „Gazdálkodás” 2010. évi 2. számában vitacikkem jelent meg „A földbirtok-politikaválaszt igénylő kérdései” címen. Ezzel az volt a célom, hogy a témakörrel kapcsolatban felvessek kérdéseket, leírjak megállapításokat, és ezzel egy olyan vitát generáljak, ami fórumot ad a tudományos közélet szereplőinek a megszólalásra, a vélemények ütköztetésére, egymás nézeteinek jobb megértésére, a politika számára javaslatok megfogalmazására. A vitában az agrárgazdaságtan, üzemtan képviselői és mások kifejthették a véleményüket olyan fontos birtokpolitikai kérdésekkel kapcsolatban, mint a földtulajdon, a földhasználat, a földbérlet, a földpiac, a mezőgazdasági üzemszabályozás, a tagosítás, a föld öröklése, a külföldiek földhöz jutása, az állam szerepvállalása és ennek...

A földbirtok-politika választ igénylő kérdései AgEcon
Kapronczai, Istvan.
A kérdések széles területet ölelnek fel, ami folytatható a földvédelemmel, a kör-nyezetvédelemmel, a földadó kérdésével stb. A politikának – kompromisszumokkal és megegyezéssel – mielőbb lépnie kell, mert a rendezett birtokviszonyok növelik a földárat, élénkítik a termőföld iránti keresletet. Az emelkedő árak ugyanakkor bővítik a földkínálatot, végeredményben élénkül az egész földpiac. Ez a leghatékonyabb eszköz a termőfölddel kapcsolatos spekulációk visszaszorítására. Van-e azonban esély a megegyezésre? Politikai síkon aligha! Sőt az agrárközgazdász szakma is meglehetősen megosztott a birtok, a föld kérdésében, hisz körein¬ken belül is hatnak az érdekek, a megcsontosodott előítéletek. Mégis szükség van egy szakmai vitára, egy őszinte véleménycserére,...

A globális gazdasági válság és a magyarországi agrárgazdaság kilátásai AgEcon
Magda, Sandor; Magda, Robert.
A tanulmány a globális pénzügyi és gazdasági válság klímaváltozás – fenntart¬hatóság – globalizáció rendszerébe illesztve olyan változásokat javasol – előnyt kovácsolva a kényszerből –, melyek számolnak a tényleges helyzettel és viszonylag kisebb áldozatokkal, valamint kockázattal megvalósíthatók. Ennek lényege tömören a termőföld-hasznosítás tudatos arányváltásai, a foglalkoztatás bővítése, integrációk szervezése és az oktatás korszerűsítése. Ajavasoltak nem veszélyeztetik hazánk élelmiszer-ellátásának biztonságát, de csökkentik az agrárágazatok, a vidék energiaköltségeit, energiafüggőségét, új munkahelyeket teremtenek, javítják a mezőgazdaságból és a vidéken élők anyagi körülményeit, hozzájárulnak az ország energiafüggőségének csökkenéséhez, így a...

A mezőgazdaságban keletkező biomassza energetikai hasznosításának agrárgazdasági megközelítése AgEcon
Molnar, Andras.
A gazdálkodás ökonómiai kérdéseivel foglalkozók számára a piaci csere híján fontos feladat az externáliák minél szélesebb körű számszerűsítése, mivel csak a társadalom számára jelentkező összes költség és haszon figyelembevételével lehet megítélni a mindenkori agrárpolitikát. Egyre fontosabb az, hogy milyen agrárpolitikai eszközökkel oldhatók meg a liberalizált kereskedelemmel szembeni elvárások és a nem-termék jellegű javak társadalmilag optimális kibocsátása. Ebben a kettős elvárásban a földtulajdon és földhasználat szétválása előnytelen. ------------------------------------------- In the absence of exchange in the market, researchers into economic aspects of farming place a high emphasis on quantifying externalities to the maximum extent possible....

A területhasználat néhány változása és következményei a Tisza-tónál AgEcon
Vasvari, Agnes; David, Lorant; Szabo, Szilard.
A Tisza-tó jelentős változásokat idézett elő a térség életében, módosult a települések térbeli kiterjedése. Ez a fajta térmódosulás a tanulmányban bemutatott ábrákon kiválóan végigkövethető. Sarud, Abádszalók és Tiszafüred esetében egyértelműen megállapítható, hogy a települések térszerkezetének eltolódása a Tisza-tó partján kínálkozó turisztikai lehetőségek hatására következett be. A településkép beépítettségében, új településrészek kialakításában, a település arculatának módosulásában szintén közrejátszott a Tisza-tó léte. A strandok településformáló hatása is jelentős a feléjük vezető lineáris infrastruktúrák fejlődésében, az út mentén lévő telkek árainak felértékelésében és a parton végbemenő változásokban (például Abádszalók). Az elárasztással...

Aggregate distribution, stability and release of water dispersible clay for two subtropical Oxisols Scientia Agricola
Azevedo,Antonio Carlos de; Schulze,Darrel Gene.
The behavior of a soil regarding the dispersion and aggregation of its particles is very important for the development of environmental and agricultural soil functions. This study was conducted to determine how aggregate distribution and stability are impacted by land uses and how the release of Water Dispersible Clay (WDC) relates to disaggregation in Oxisols from subtropical Brazil. Samples from two Oxisols, collected at three depths from sites under no-tillage (NT), conventional tillage (CT) and native vegetation (NV) land uses were shaken in 250 mL plastic bottles for intervals up to 27 hours. The mass of aggregates was measured in five size classes ranging from 53 to 2000 µm. Most aggregates larger than 500 mm disappeared during the first 7.5 hours of...

AGRICULTURAL COOPERATIVES AND THEIR DEVELOPMENT AFTER THE TRANSFORMATION AgEcon
Lazikova, Jarmila; Bandlerova, Anna; Schwarcz, Pavol.
Agricultural cooperatives in Slovakia still represent the most important legal form of enterprises in agriculture. Chosen indicators of financial analysis and indicators of revenues as calculated to hectare of agricultural land show that the transformed agricultural cooperatives in Slovakia are able to keep in step with newly created business companies. The paper tries to answer the question why the agricultural cooperatives in Slovakia still maintain their dominant position in agricultural business while in other countries of Central Europe agricultural cooperatives play only an insignificant role.

AGRICULTURAL LAND PROTECTION POLICY FOR ALBANIA: LESSONS FROM WESTERN EUROPE, NORTH AMERICA, AND JAPAN AgEcon
Jacobs, Harvey M..
This report has been prepared as one effort to assist the Albanian government in formulating a policy approach appropriate to the conditions and culture of their country. The goal of this report is to examine the approach to agricultural land protection in other parts of the world, for the lessons they can provide to Albania. There is little recent literature on the subject of agricultural land protection policies. Most of the articles found in the English-language literature are six to ten years old, and in turn often rely on other sources that are several years older still. Thus, this survey should be viewed as a somewhat dated catalog of policy approaches which have been used at various times in the respective jurisdictions rather than as a statement of...

AMENITY BENEFITS AND PUBLIC POLICY: AN APPLICATION TO THE CONNECTICUT DAIRY SECTOR AgEcon
Lopez, Rigoberto A.; Altobello, Marilyn A.; Shah, Farhed A..
This article develops a conceptual framework for analyzing the role of state-level policies towards the dairy sector in the presence of farmland amenity benefits, and applies it to Connecticut. Milk supply, demand and amenity benefit functions are estimated, and three exogenously determined milk prices are considered. The empirical findings show, under each price scenario, the extent to which land is underallocated to the dairy sector if amenity benefits are ignored. Analysis of policy options reveals that a partial production cost subsidy represents the least-cost alternative for attaining the socially optimal solution for the region.

AN AGENDA FOR THE STUDY OF LAND USE, WILDERNESS DESIGNATION, AND RESOURCE REGULATION IN THE AMERICAN WEST AgEcon
Batabyal, Amitrajeet A..
Atemporal and intertemporal use of public lands, the determination of optimal levels of wilderness designation and habitat preservation, and the appropriate regulation of natural resources have all been "hot button" issues in the American West for quite some time now. In this paper, I propose and describe a research agenda which promises to yield interesting and useful new policy insights into these fractious resource issues.

An Overview of the Implications of Global Change for Natural and Managed Terrestrial Ecosystems Ecology and Society
Walker, Brian; CSIRO Sustainable Ecosystems; Brian.Walker@csiro.au; Steffen, Will; ; Will.Steffen@dwe.csiro.au.
Global change is the net effect of individual and interactive effects of changes in land use, atmospheric composition, biological diversity, and climate. A synthesis of the past six years' activities of the Global Change and Terrestrial Ecosystems project of the IGBP (International Geosphere-Biosphere Programme) deals with global change effects as ecosystem responses and living with global change. Ecosystem responses are considered in terms of changes in function and vegetation composition/structure. Field experiments of elevated CO2 effects on aboveground biomass show, on average, a positive effect on biomass, ranging from -20% to +80%. Some early predictions of CO2 effects (C3 vs. C4 plants, N-fixers, C:N in litter) are not generally supported, and it...

Análisis multitemporal de la dinámica en el cambio de uso del suelo rural-urbano en la región de Atlixco, Puebla. Colegio de Postgraduados
Luna Fernández, Víctor Genaro.
La presente investigación se llevó a cabo en la región de Atlixco, Puebla, en las comunidades de San Pedro Benito Juárez y Nexatengo. Tuvo como objetivo conocer la dinámica en el cambio de uso del suelo en la región de Atlixco durante el periodo de 1977 al 2007 y la relación que existe en función de los factores sociales, económicos, agrícolas y ambientales. La importancia de estudiar estas relaciones desde un enfoque sistémico radica en tratar de comprender el funcionamiento de la sociedad desde una perspectiva holística e integradora, en donde lo importante son las relaciones entre los componentes, desde el punto de interés del todo y no solo el de las partes que son inherentes al problema. Debido a que el problema analizado se encuentra dentro de un...

Analysis of soybean cropland expansion in the southern Brazilian Amazon and its relation to economic drivers Acta Amazonica
GUSSO,Anibal; DUCATI,Jorge Ricardo; BORTOLOTTO,Virindiana Colet.
ABSTRACT The agricultural dynamics of soybean expansion have long been recognized as a major driver of excessive land cover change on the southwestern border of the Brazilian Amazon. The hypothesis that the soybean market exerts an influence on land use was investigated by the association between economic indicators and soybean crop dynamics in the state of Mato Grosso (western Brazil). We integrated a historical series of satellite data of soybean cropland expansion and the two main economic variables (selling prices and production costs) for soybean in Mato Grosso. We focused on the relation between profit (the difference between the average soybean price and production costs) and land-use transition to soybean from 2001 to 2013. The spatially explicit...
