This study tests cropland contract hypotheses utilizing a landlord data set. Ordered probit and classical regression models are estimated and presented identifying factors that affect the contract type selection and terms. Results suggest credit constraints are a viable land-leasing hypothesis. Risk aversion, managerial ability, and social capital are also supported.
Este trabajo calcula el valor del regadío en la provincia de León a partir de datos de precios de la tierra desagregados por aprovechamiento y comarca. El valor de los beneficios asociados al regadío puede averiguarse comparando dos parcelas de tierra "iguales" excepto por el hecho de que una de las tierras sea de secano y la otra de regadío.
The terms of grazing lease contracts potentially influence the tenants incentive to preserve the vegetation resource. Annual stocking rate decisions dictate the degree of overgrazing, which can be cumulative over long periods of time. The objective of this study is to identify the impact the tenants planning horizon and cost structure specified in the lease contract has on his/her profit-maximizing stocking rate. A multi-period nonlinear programming model was developed to identify economically optimal stocking rates each year over a 24-year period.
The objective of this paper is to present a way of complementing empirical results with farmers' perceptions in defining limiting biophysical land properties in a land suitability evaluation using the FAO framework methodology. The farmers' perceptions were identified using rapid and participatory rural appraisal (RRA/PRA) tools. The study catchment, having a semiarid continental climate and located on the Loess Plateau in northern China, covered an area of 3.5 km2. Most of the land users were dependent on subsistence agriculture.
The increasing problem of landlessness in Ethiopia has put pressure on regional governments to redistribute land. In 1997 and 1998, a major land redistribution was undertaken in the Amhara Region, reducing landlessness where implemented. While the impacts of such redistributions have been hotly debated, little empirical evidence exists concerning the actual impacts of redistribution.
The development of a land rental market in China may help stimulate further increases in agricultural production. This paper provides a description of land rental transactions in rural China, analyzes the determinants of land supply and demand and estimates the implications land rental activity has for increasing agricultural production.
Increasing world population and the depletion of natural resources due to imbalances in development necessitates a new approach to development and the use of natural resources. Controlled adaptive planning, design, and judicious management of these precious resources seem to be a more logical approach towards resource conservation and sustainable development. This requires careful consideration and understanding of all attributes of a proposed site in order to suggest the appropriate form of development that will be in harmony with existing natural forces acting on the site.
This article reviews intellectual property rights (IPRs), with some emphasis on the protection of agricultural and life sciences innovations. The main institutional features of IPRs are first discussed, along with a brief historical background and an articulation of the main rationale for the existence of such rights. This is followed by an overview of the principal economic issues related to IPRs.
Counter intuition, an analysis of tree‐line position across the Swiss Alps based on a geographical information system (GIS) with a spatial resolution of 100 m (2.5 million points) revealed no difference in climatic tree‐line altitude with slope exposure. Through step wise discrimination procedures our analysis accounts for anthropogenic tree‐line depression. Any land cover bias affects the frequency of GIS‐points corresponding to tree‐line forests rather than the mean elevation of such points, captured by our analysis.
