This paper analyses the determinants of household farms’ participation in land rental markets in transition countries and what affects their access to land through rental markets. We derive several theoretical hypotheses on the impact of households’ management ability, land endowment, land quality and prices, transaction costs in the land market, rural credit and labour market constraints. We t...

Agriculture is important to New Zealand's economy. Like other primary producers, New Zealand strives to increase agricultural output while maintaining environmental integrity. Utilising modelling to explore the economic, environmental and land use impacts of policy is critical to understand the likely effects on the sector. Key deficiencies within existing land use and land cover change models ...

Marginal farm land is land characterised by low food, feed and fodder crop productivity due to soil and environmental limitations. Such land may however be utilised for bio-energy crop production. We investigate the economic viability of small scale combined heat and power anaerobic digestion (CHP AD) projects based on feedstock from farm waste and bio-energy crops grown on a representative tem...

We aimed at quantifying the extent to which agricultural management practices linked to animal production and land use affect environmental outcomes at a larger scale. Two practices closely linked to farm environmental performance at a larger scale are farming intensity, often resulting in greater off-farm environmental impacts (land, non-renewable energy use etc.) associated with the productio...

rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...

Although land plays a crucially important role in economic development and structural transformation, the causes and consequences of the evolution of farming land have only been paid scant attention in recent decades. In this paper I document changes in the extent of global farming land and in average farm sizes. I show that the spatial distribution of global farming land has changed dramatical...

To assist water resource managers with future land use planning efforts, the eco-hydrological model Soil and Water Assessment Tool (SWAT) was applied to three catchments in South Australia that experience extreme low flow conditions. Particular land uses and management issues of interest included forest covers, known to affect water yields, and farm dams, known to intercept and change the hydro...

Informal land markets, particularly land rental markets, are emerging rapidly in many parts of subSaharan Africa (SSA). Land rental markets have the potential to contribute to structural transformation if, for example, such markets facilitate the transfer of land from less productive to more productive farming households. Although there is a growing literature on the determinants of smallholder...

Structural change in agriculture is characterized by the interdependency of farms’ growth decisions due to scarcity agricultural land . This paper adds sparse empirical literature on relation between market concentration and farm size changes, considering different definitions relevant market. Using data from Integrated Administrative Control System (IACS) 2005 until 2017 for Brandenburg, Germa...

n-farm research is motivated by a desire to learn more about a product/practice/system on land you manage. You may now have the tools (yield monitor, weighing grain cart, etc.) to accomplish on-farm research that generates information you can use in management decision-making. Your on-farm research should start with the design of a “valid comparison”, according to your research objective (Soil ...
