This paper does two things. First, it develops a game theoretical model over population groups that optimize their survival under resource scarce conditions. The model includes two rather obvious, but in the theoretical literature neglected, strategies - survival by migration and, once a...

Traffic accidents with wild boar have increased rapidly over the last years in Sweden. This paper calculates and predicts costs of current and future accidents, totally and for different Swedish counties, based on estimates of wild boar populations. A logistic population model is assumed, and...

Using solar energy through photovoltaic systems implementation in an agricultural household leads to the increasing of it’s efficiency, to optimizing energy balance thus implying the decreasing of the primary energy costs. The solar energy refers to a renewable energy source that is produced...

Water scarcity in Balochistan is more severe as of Pakistan. Ground water level is depleting day by day. One of the solutions for such problem is to store water through mini-dams. This study is conducted to find an impact of mini-dam on agricultural productivity in Ziarat, taking apple as the...
