Zambia and particularly the Eastern province have one of the highest rates of malnutrition in the world. The most vulnerable are the children from rural households which depend entirely on seasonal agricultural production and income, and survive on diets that are deficiency in proteins and other...

The study investigates whether African agricultural efficiency levels has been improving or not and what drives its over the years based on 442 frontier studies using meta-regression analysis. The results show that mean efficiency estimates from studies decrease significantly as year of survey...

This paper presents some evidence of a positive effect of Agriculture R&D investment on economic growth in general dynamic setting using annual data for 57 developing countries for the period 1981-2010. The potential endogeneity of Research and Development Investment is also addressed to...

We investigate the environmental effects due to pesticides for two different genetically modified (GM) seeds: insect resistant (IR) cotton and herbicide tolerant (HT) soybeans. Using an agricultural production model of a profit maximizing competitive farm, we derive predictions that IR trait...

Increasing temperature and variability in precipitation in the semi-arid regions have reduced crop yields and increased vulnerability of the farmers. This paper has estimated the vulnerability of both farmers and irrigation tanks to rainfall variability in a rain-fed area. It has also looked...

Rainfall and temperature are the two important weather factors that affect crop yields due to their direct and indirect influences on agricultural practices. This study has negated the method of direct use of meteorological factors (either monthly or seasonal), in multiple regression analysis to...
