The paper has some approaches for aspects that are part of the relations between agriculture and the natural environment in which they reside, without its favorability, its existence couldn't be conceived. The manifestation of some environmental components is on the same wave length as the need to satisfy the development of plants, which has a negative impact on agricultural activities and on the economic and production results of exploitations, them manifesting as natural risk factors that are highlighted by climate phenomenon newly developed. Considering the above-mentioned relations, there was followed the trend for vegetable production on a ten years timeframe and the effects of oscillations on some economic results of the branch and some synthetic indicators representative for economic growth.

The increasing demand for agricultural products partly due to the high population growth requires agriculture to struggle for productivity improvement. However, productivity search is constrained by environmental preoccupations, raising the question of agricultural development models to be adopted to increase productivity while limiting environmental consequences. This paper examines the role of market orientation by assessing the effect of agricultural commodity export on greenhouse gas emissions relatively to local market oriented agricultural production model. Using panel data from 1986 to 2010 for 136 countries around the world, and accurate instrumental variables technique, the findings suggest that the proportion of primary commodity export in agricultural production increases greenhouse gas emissions. These results are robust to different sources of agricultural export and environmental data, and to the inclusion of additional control variables. [ABSTRACT FROM AUTHOR]

A common factor that explains why agriculture causes too much environmental degradation, grows too slowly, and has been ineffective in reducing rural poverty is the generalized tendency by governments to under invest in public goods despite the high rates of return to such investments. A large share of rural public expenditures is deviated to private goods (mostly subsidies to the wealthy), which generally have low or even negative rates of return. Behind such an obviously aberrant choice are political economy forces; a highly unequal political lobby market leads to government policies that are biased in favor of economic elites and detrimental for both the environment and rural development. Globalization may affect this important distortion on the allocation of government expenditures in various ways. One such way is by restricting the ability of governments to repress the political mobilization of the poor to counter the almost unchallenged power of the elites in the lobby market. This may contribute toward creating conditions that are more consistent with sustainable and socially equitable development. [ABSTRACT FROM AUTHOR]
