Agricultural productivity is determined and limited in general by a combination of the natural environment and technical measures. If non-capital intensive management is assumed, the natural potential and constraints are of specific importance for the agricultural land use and its productivity. In this context, the Potsdam Institute for Climate Impact Research (PIK) in cooperation with the Max ...

This study aimed at investigative decision support systems for assisting strategic and tactical decision making of smallholder farmers to reduce climate risks and increase crop productivity of semi-arid areas. Specifically, the study assessed farm-level decisions used by the farmers for reducing climate risks; examined information communication and knowledge sharing strategies for enhancing dec...

abstract comparison of food prices in different periods, indicates fluctuations and continually upward trend. any change in agricultural sector variables, as main food supplier, will affect food price. productivity shocks and production gap are examples of such variables. in this paper ,hodrick prescott and kalman filters are used as generators of productivity shocks and production gap series. ...

In this paper we explore the incentives of low income agricultural producers to adopt soil carbon sequestration, focusing particularly on the impact of risk. A dynamic optimization model of the farm level decision to adopt conservation is then presented, where farmers’ optimize over the expected utility of profits from agricultural and carbon sequestration activities. Carbon sequestration adopt...

This paper analyses, within the new growth theory framework and using panel cointegration techniques, the effect of agricultural international technological spillovers on total factor productivity growth for a sample of 47 countries during the period 1970-1992. The analysis shows that total factor productivity is strongly influenced by domestic as well as foreign public R&D spending in agricult...

Structural transformation is a process by which the relative contribution of nonagricultural sectors to the overall economy rises as agriculture’s share declines in relative terms. In absolute terms, however, agriculture continues to grow and contribute to overall economic growth. Agricultural productivity growth and increased farm incomes are prerequisites for structural transformation. Increa...

investing in research and development spending (r&d) affects total factor productivity (tfp).recently new theories of economic growth have emphasized the relationship between r&d and tfpand also identified a number of channels through which a country’s r&d affects tfp of its tradepartner. this study seeks to estimate the effect of agricultural r&d and education spending and some...

Agriculture is critical for human welfare, providing food, employment, income, and assets. In the past, agricultural research and development largely focused on improving production, productivity, and profitability of agricultural enterprises. Nutrition and other benefits of agriculture were not always optimized, while the negative impacts on health, well-being, and the environment were often i...

Agricultural labor productivity is key for understanding aggregate cross-country income differences. One important proximate cause of low agricultural productivity is the low use of intermediate inputs, such as fertilizers, in developing countries. This paper argues that farmers in poor countries rationally choose to use fewer intermediate inputs because it limits their exposure to large uninsu...
