Danos causados aos arrozais por cigarrinhas das pastagens.
Provedor de dados: 14
Autores: FERREIRA, E.; GUAZZELLI, R. J.
Observou-se um ataque incomum do insto nas lavouras de arroz em Goiás. Para isto contribuiram: a) condições climáticas favoráveis, isto é, choveu mais cedo, em outubro, e as chuvas se mantiveram com regularidade favorecendo a eclosão das ninfas do inseto e seu desenvolvimento; b) o aumento da área de pastagens com gramíneas, altamente susceptíveis como Brachiaria decumbens cv. australiana, cv. IPEAN e B. ruziziensis; c) o plantio de lavouras de arroz e outras gramíneas nas proximidades das áreas com pastagens.

SOCIAL IDENTITY AND MANIPULATIVE INTERHOUSEHOLD TRANSFERS AMONG EAST AFRICAN PASTORALISTS
Provedor de dados: 31
Autores: Huysentruyt,   Marieke; Barrett,   Christopher B.; McPeak,   John G.
We model interhousehold transfers between nomadic livestock herders as the state-dependent consequence of individuals' strategic interdependence resulting from the existence of multiple, opposing externalities.  A public good security externality among individuals sharing a social (e.g., ethnic) identity in a potentially hostile environment creates incentives to band together. Self-interested interhousehold wealth transfers from wealthier herders to poorer ones may emerge endogenously within a limited wealth space as a means to motivate accompanying migration by the recipient.  The distributional reach and size of the transfer are limited, however, by a resource appropriation externality related to the use of common property grazing lands. When this effect...

Autores: Bazen,   Ernest F.; Roberts,   Roland K.; Travis,   John; Larson,   James A.
Understanding the interactions between supply and demand for hay is important because of hay’s significance to the agricultural sector and economy, and because hay is an important crop on highly erodible soils. As an example, Tennessee has the most erodible cultivated cropland in the United States (Denton, 2000), nearly half of the state’s current CRP acreage contracts are set to expire in 2007 (U.S. Department of Agriculture, 2006), and hay is one of the most economically important crops produced in the state (U.S. Department of Agriculture, 2004). Cross (1999) attributed the upward trend in Tennessee hay acreage since 1980 to an increasing number of farmers who were searching for alternative production activities, such as hay, pasture and livestock, to...
