    A synergetic linkage between agricultural productivity, nutrition and health
    (2013-01) Agulanna, F. T.; Ikpi, A. E.; Okoruwa, V. O.; Akinyosoye, V. O.
    This study examined the effect of health and nutrition on labour productivity of farmers in South-western Nigeria. Within this geo-political zone of the country, primary data was collected through a field survey of 470 rural farmers. Descriptive statistics, Anthropometric measures of nutrition (BMI and DDS) and the Tobit model were used to show the effect of nutrition and health on the productivity of farmers. Estimated results show that body mass index (BMI) and dietary diversity score (DDS), which are nutritional variables, have effect on the frequency of the occurrence of sickness of rural farmers in the study area; thus affecting their productivity. These results help to establish the synergy between health, nutrition and productivity. Moreover, the policy implication of these findings point to the fact that poor health and malnutrition adversely affect productivity of labour, inversely establishing the fact that good health is a key element of development and a driver of growth. The need arises, therefore, to invest more on human capital, especially health in order to enhance the productive capacity of rural farmers.

    Productivity impact differential of improved rice technology adoption among ricefarming households in Nigeria
    (Journal of Crop Improvement,, 2011) Dontsop Nguezet, P. M.; Okoruwa, V. O.; Adeoti, A. 1.; Adenegan, k. O.
    The contribution of technological change to agricultural productivity in developing countries has long been documented. It is believed that the adoption of new agricultural technologies, such as high-yielding varieties, could lead to significant increases in agricultural productivity and stimulate the transition from low-productivity, subsistence agriculture to a high-productivity agro-industrial economy. The article uses the local average treatment effect (fATE) to estimate the impact of adoption of improved rice varieties on rice farmers' productivity in the three major rice ecologies of Nigeria. A stratified random sampling was adopted by the study to select a sample of 500 rice farmers across ecologies. Findings of the analysis indicated that adoption of improved varieties helped raise farmers' area harvested and yield per hectare, respectively, by 0.39 hectare and 21 7.9 kg/ ha for NERTCA and 0.51 hectare and 2.10.4 kg/ ha for other improved varieties, thereby increasing their productivity. In addition, NERICA varieties performed better than any other upland improved variety and the impact of its adoption on both area harvested and yield was greater among female rice farmers than among their male counterparts. Intervention programs to increase the dissemination of high-yielding rice varieties to areas with low productivity are, therefore, a reasonable policy instrument
