Impact of nigerian agricultural policies on crop production and the environment
SummaryNigerian efforts in agricultural development over the past three decades have failed to improve the country's economy. A review of the sector depicts a gloomy picture. Performance is reflected in environmental degradation, mounting food deficits, and decline in both gross domestic product and export earnings, while retail food prices and import bills have been increasing. These effects have further impoverished the smallholder farmers, locking them into a poverty web. The Government must seek to establish agricultural strategies which promote political stability, self reliance, public participation, sustained production and environmental security.
The migrant Igbira farmers and food crop production in Bendel State, Nigeria
Abstract The migrant Igbira farmers produce the bulk of the foodstuff which supports the high concentration of non-farming urban population in Bendel State. The migrants are professional food crop farmers whose push and pull factors of migration are motivated by access to farmland and cash income from food crop production. These farmers fill the gap left by subsistence indigenous farmers who produce food mainly for household requirements. This study examines the farming techniques and profitability of land use by the migrant farmers. Data were collected from 500 Igbira farmers from Bendel North Senatorial District where these farmers are found. Three sources of data were employed: discussions with migrant farmers, farm observations and a questionnaire survey. The results of data analyses indicate that migrant farmers were attracted to areas of abundant farmland in hospitable environments that were located near to their natal settlements. The financial evaluation of land use showed that the net income from land per hectare varied from 60 for pepper through 735 for melon to 7830 for yam. Similarly, the net present worth gave 10 178 per hectare while the benefit cost ratio was 2·8. Nevertheless, high cost of seed yams, unstable market prices for food crops and inadequate labour supply were the main factors that inhibit food crop production by the migrant farmers.
