Indian agriculture is the largest private sector enterprise in the country of over 110 million farmers. It engages two-third of total workforce, contributes to 26 per cent of the GDP and nearly one-sixth of the total export earnings. India inherited a stagnant agriculture at the time of independence growing at an annual rate of growth of 0.3 per cent in the first half of the last century. Due t...

Catastrophic collapses of top predators have revealed trophic cascades and community structuring by top-down control. When populations fail to recover after a collapse, this may indicate alternative stable states in the system. Overfishing has caused several of the most compelling cases of these dynamics, and in particular Atlantic cod stocks exemplify such lack of recovery. Often, competition ...

a basic subject in economy is change in growth of population and it’s link to ‎other variables. if growth in population is consistent with other economic ‎circumstances, it would lead to economic growth, otherwise it would be ‎problematic. by using okun's law and population structures, this paper is ‎analysis the case for iran for 1974-2010. predictions are related to 2025 ‎horizon. the re...

Qualitative and quantitative differences in population growth patterns of Aphelenchoides rutgersi from Florida, A. sacchari from Jamaica, A. dactylocercus from Great Britain, and A. cibolensis from New Mexico were assessed on 28 species of fungi. The patterns of population growth of A. rutgersi and A. sacchari were statistically similar although not identical, and they differed considerably fro...

Introduction Conclusions References

Harsh conditions (e.g., mortality and stress) reduce population growth rates directly; secondarily, they may reduce the intensity of interactions between organisms. Near-exclusive focus on the secondary effect of these forms of harshness has led ecologists to believe that they reduce the importance of ecological interactions, such as competition, and favor coexistence of even ecologically very ...

This research argues that the rapid expansion of international trade in the second phase of the industrial revolution has played a major role in the timing of demographic transitions across countries and has thereby been a significant determinant of the distribution of world population and a prime cause of the ‘Great Divergence’ in income per capita across countries in the last two centuries. T...

The Latin America and the Caribbean region is one of the most urbanized regions in the world, with a total population of around 630 million that is expected to increase by 25% by 2050. In this context, detailed and contemporary datasets accurately describing the distribution of residential population in the region are required for measuring the impacts of population growth, monitoring changes, ...
