“…Widawsky and Rozelle (1998) using data from regions of China found, instead, that the number of planted varieties reduces both the mean and the variance of rice yield. Di Falco and Perrings (2005), found a positive relationship between crop biodiversity and agricultural production in a case study on cereal production in southern Italy. Di Falco and Chavas (2006) found a positive correlation between crop genetic diversity and productivity.…”

“…5 Some applied economists have focused on the empirical assessment of the determinant of in situ crop biodiversity (e.g., Evenson, and Gollin 1997;Heisey et al 1997;Smale, Bellon, and Aguirre Gomez 2001;Smale et al 2003;Di Falco and Perrings 2005). Other authors have addressed the issue of the measurement of biodiversity (Solow, Polasky, and Broadus 1993;Weitzman 1992) and its role on potential commercial profits and its social value (e.g., Goeschl and Swanson 2002;Simpson, Sedjo, and Reid 1996). implications for resilience.…”

ABSTRACT. This paper investigates the dynamic effects of rainfall shocks on agroecosystems productivity. The analysis estimates a panel data model of cereal production in southern Italy. It documents the adverse effects of a reduction in rainfall on the agroecosystem productivity both in the short run and the long run. It investigates how increasing the level of spatial crop diversity can mitigate this negative impact. The empirical evidence shows how higher diversity supports resilience and maintains the system productivity under challenging climatic conditions. (JEL Q24, Q54, Q57)

“…Yet, on the other hand, gaining of economic profits by improving agrarian structure and recovering infrastructure, can affect the landscape diversity as a consequence of decreasing number of mid-field balks, being field margins tiny uncultivated strips of lands, which demarcate land possession. Additionally, enlargement of arable plots done by removal of small biotopes, resulting in decline of biodiversity, not mention about lowering aesthetic values of landscape (Herzog 1998, Di Falco, Perrings 2005, Miranda et al 2006, Sklenicka 2006. Undoubtedly, it has consequences on cultural landscapes, because it leads to more homogeneous landscape and the loss of cultural value (Pasakarnis et al 2013).…”

abstract. Fragmentation of agricultural landscape is a specific feature of agrarian structure in Poland. Despite the fact that consolidation work has been carried out for years, the positive effects are still negligible. This is because land consolidation in Poland is encountering with a number of obstacles, which on the one hand, is cumbersome formal and legal policy, and on the other hand, disapproval of officials and farmers as well. These barriers unnecessarily prolong the proceeding, which is inherently long-term, sometimes takes years and not always is successfully completed. For this reason an effort was made to answer the question: how improving in land consolidation policy may look up the efficiency of land merging work in Poland? Two formal procedures were presented, on the basis of which land consolidation is carried out in two voivodeships: Wielkopolskie and Dolnośląskie. The study revealed the main obstacles and weaknesses in legal regulation. Additionally, open-interviews among farmers as well as local and regional land consolidation authorities, were undertaken. On the basis of the acquired data, a number of new suggestions to more successful land consolidation policy, were put forward. Finally, possible solutions to perk up the land unification work were established. key worDs: agrarian structure, land fragmentation, patchwork, chessboard, plot distribution pattern, Wielkopolskie and Dolnośląskie voivodeships.

“…Based on our earlier observation from pig production, it may be argued that integrating the peas and rapeseed on the dairy farm could lead to further reductions in GHG emissions in milk production. The trade off, however, is that increasing crop diversity also limits economies of scale and may decrease farm net revenues and increase labour cost (Di Falco and Perrings, 2005). The clover-grass silage used in the local scenario decreases the roughage content of the diet, resulting in about 3% increase in feed digestibility (Table 2), which in turn reduces enteric CH 4 emissions per unit of feed intake (McAllister et al, 1996).…”

Livestock farmers in Sweden usually grow feed grains for livestock but import protein feed from outside Sweden. Aside from the economic implications, some environmental issues are associated with this practice. We used life cycle assessment to evaluate the impact of local protein feed production on land use and greenhouse gas emissions, compared with the use of imported protein feed, for pig meat and dairy milk produced in Sweden. Our results showed that local production reduced greenhouse gas emissions by 4.5% and 12%, respectively, for pigs and dairy cows. Land use for feed production in Sweden increased by 11% for pigs and 25% for dairy cows, but total land use decreased for pig production and increased for dairy milk production. Increased protein feed cultivation in Sweden decreased inputs needed for animal production and improved some ecological processes (e.g. nutrient recycling) of the farm systems. However, the differences in results between scenarios are relatively small and influenced to an extent by methodological choices such as co-product allocation. Moreover, it was difficult to assess the contribution of greenhouse emissions from land use change. The available accounting methods we applied did not adequately account for the potential land use changes and in some cases provided conflicting results. We conclude that local protein feed production presents an opportunity to reduce greenhouse gas emissions but at a cost of increasing land occupation in Sweden for feed production.
