The main goal of the study is to quantify the effects of a) change in nitrogen fertilization rate, b) adjustment of sowing date, c) implementation of new cultivars, and d) supplementary irrigation on maize cropping systems across six African countries including Ghana, Nigeria, Kenya, Malawi, Ethiopia and Burkina Faso. For this purpose, 30 years (1980-2010) of climate data are used as well as soil and management information obtained from global datasets at 0.5° x 0.5° spatial resolution.
It is now widely acknowledged that biotechnology will have significant implications for development. While biotechnology’s potential for low income economies is still the subject of controversy, this paper argues that it is precisely in these countries that food and agriculture related biotechnology could efficiently contribute to the achievement of development objectives. To date, however, biotechnological advances have been realized predominantly in industrialized countries.
This paper considers genetically modified (GM) seed adoption decisions by farmers in a developing country under two alternative information regimes (with and without perfect information regarding production conditions) that allows the monopolist producer of GM seeds to either practice perfect discrimination or uniform pricing. Under each regime we analyze two scenarios: when the government can and cannot credibly commit to the announced form of welfare enhancing intervention in the domestic seed market.
Innovations are fast changing the agricultural landscape driven by the increasing need to shift towards sustainable practices without sacrificing the productivity and profitability of farming. Innovations in technology, institutions, processes, and products have contributed to the growth of agriculture, globally and in developing countries including India and Africa, as observed in the cases of green revolution in cereals; and gene revolution in cotton.
The first section of this paper outlines the effect of gender norms on the productivity and incomes of women in the agricultural sectors of various African countries. The main challenges faced by women in value chains are outlined, including limited land rights, lower education levels and lower financial inclusion, as well as traditional division of labour in the household. These constraints are examined in turn, and their implications in terms of agricultural productivity and earnings are discussed.
En esta comunicación se argumenta en torno a las ventajas de contar con una “Educación Intercultural sobre el Cambio Climático” como vía para empoderar a las comunidades locales. Se propone una metodología para la recuperación y valoración del estado de vitalidad/erosión intergeneracional de los conocimientos tradicionales sobre el cambio climático.
