1. introduction the phenomenon of land consolidation has been the concern of economists, geographers, soil scientists, anthropologists, and politician in the last decades. it has achieved little success for agricultural development in iran. most of iranian land consolidation schemes ignore to meet sustainability criteria as a critical phase in the planning process. therefore, they have caused m...
Sub-Saharan Africa is experiencing major changes in farm land ownership and use, which are both cause and consequence of the economic transformations that the region is now experiencing. The rapid rise of emergent investor farms in the 5 to 100 hectare category represents a revolutionary change in Africa’s farm structure since 2000. The rise of investor farmers is affecting the region in divers...
This study aimed to assess the merit and suitability of individual functional units (FU) in expressing greenhouse gas emissions intensity in different dairy production systems. An FU provides a clearly defined and measurable reference to which input and output data are normalised. This enables the results from life-cycle assessment (LCA) of different systems to be treated as functionally equiva...
EXTENDED ABSTRACT The end user requirement for this development is to be able to assess the impact of land use changes on groundwater quality, specifically that due to nitrate leaching from agriculture. Implementation will be for alluvial plains at scales up to about 2000 km. GIS databases provide information on land use and soils. This information, at individual field and farm scale, enables m...
this article examines the livelihood strategies of land scarce peasants in ethiopian. land scarce peasants have a limited livelihood security on a sustainable manner and bypassed by major development programmes. the study was centred on two sets of rationales. first, for those peasants who do not have sufficient farmland, agriculture provides only a limited portion of households’ livelihood sec...
This paper develops a model to understand the mechanism that might explain how land rights security may facilitate labor specialization. The theoretical framework suggests that with secured land rights, households with high farming ability are likely to invest in land while households with low farming ability tend to investment in human capital and migrate. Land security is identified as whethe...
Land uses has significant impact on soil biological properties that incessantly intimates the soil quality change and are assessed by soil microbial and biochemical indicators, as they are highly sensitive to change in environment. The purpose of this study was to investigate the impact of land use on soil enzyme activities and gene diversity in selected location of Northwestern Himalayas, Indi...
An agricultural policy option where individual producers’ support prices increase with the proportion of land set-aside is evaluated. A theoretical framework is presented and a stochastic simulation model is developed to generate estimates of the impacts of the policy on aggregate and regional distribution of government payments and farm-level income. Results indicate that significant land idli...
Land redistribution was legislated in 1994; it was designed to resolve historical imbalances inland ownership in South Africa. Between 2002 and 2006, a longitudinal observational studywas conducted with 15 purposively selected small-scale dairy farmers in a land redistributionproject in Central North West Province. Four farmers left the project over the period. For thepurposes of this study, a ...
Smallholder farming systems in sub-Saharan Africa have undergone changes in land use, productivity and sustainability. Understanding of the drivers that have led to changes in land use in these systems and factors that influence the systems' sustainability is useful to guide appropriate targeting of intervention strategies for improvement. We studied low input Teso farming systems in eastern Ug...
