in this study, considering the importance of incremental capital output ratio (icor) in agriculture investment capital and self-sufficiency in this sector in order to grow and being influenced by the past and previous relationships strong agricultural sector productivity growth in other sectors of the economy, especially the effect of oil revenues, was trying to, long-term relationships as well...

Agricultural productivity, and its variation in space and time, plays a fundamental role in many theories of human social evolution. However, we often lack systematic information about the productivity of past agricultural systems on a scale large enough to test these th...

Capitalizing on the most recent worldwide estimates of the impacts of climate change on agricultural production, this paper assesses the economic effects of climate change for Southeast Asian countries through 2080. The results suggest that the aggregate impacts of agricultural damages caused by climate change on the global economy are moderate. However, the uneven distribution of productivity ...

Starting in the 1970’s, the Brazilian agricultural sector has experienced an important process of modernization, whose principal effects include advances in technological progress and gains in productivity. The primary objective of this paper is to analyze technological progress and total productivity growth in the Brazilian agricultural sector during the period from 1970 to 1996. The methodolo...

We ask whether prime-age adult mortality due to HIV/AIDS decreases the endowment of knowledge for agricultural production in Kagera, Tanzania, reducing total factor productivity. We also quantify how much this negative effect contributes to the decrease in long-term household agricultural income growth compared to the contribution of decreased accumulation of productive assets; household member...

Abiotic stress limits crop productivity [1], and plays a major role in determining the distri‐ bution of plant species across different types of environments. Abiotic stress and its effects on plants in both natural and agricultural settings is a topic that is receiving increasing at‐ tention because of the potential impacts of climate change on rainfall patterns and tempera‐ ture extremes, sal...

BACKGROUND: Seed can play a critical role in increasing agricultural productivity: it determines the upper limit of crop yields and the productivity of all other agricultural inputs to the farming system. In the mid-1970s, governments and donors recognized the critical role of seed in agricultural transformation and began to provide substantial support for seed system development. Since then, F...

Agriculture is the largest sector in most sub-Saharan economies in terms of employment, and it plays an important role in supplying food and export earnings. Rural poverty rates remain high, and labor productivity is strikingly low. This paper asks how these factors shape the role of agriculture in African development strategies. Is agricultural growth a prerequisite for growth in other sectors...
