In the past 50 years, the application of synthetic nitrogen (N) fertilizer to farmland resulted in a dramatic increase in crop yields but with considerable negative impacts on the environment. New solutions are therefore needed to simultaneously increase yields while maintaining, or preferably decreasing, applied N to maximize the nitrogen use efficiency (NUE) of crops. In this review, we outline the definition of NUE, the selection and development of NUE crops, and the factors that interact with NUE.
African agriculture is currently at a crossroads, at which persistent food shortages are compounded by threats from climate change. But, as this book argues, Africa can feed itself in a generation and help contribute to global food security. To achieve this Africa has to define agriculture as a force in economic growth by: advancing scientific and technological research; investing in infrastructure; fostering higher technical training; and creating regional markets.
This edition of “The Outlook for Agriculture and Rural Development in the Americas,” covering 2015-2016, is divided into the following four chapters:
Chapter I: Macroeconomic Context: The author analyzes the evolution and outlook for financial and macroeconomic markets, which determine the conditions in which agriculture in the Americas will have to operate.
Increasing of agriculture products is of importance so that research and development in this branch considers as one of the most important infrastructure which develops production growth. Agriculture provides new and improved findings regarding inputs and production methods hence R&D efficiency increases and leads to potential creation in increasing of agriculture products and reduces pressure on natural resources.
In response to population growth, rising income and urbanisation, the demand for livestock products, such as milk, meat and eggs is growing in Ethiopia. The growing demand for milk products offers opportunities for smallholders to realize better livelihoods. Whereas the growing demand for milk products in Ethiopia is widely recognised, the dairy sector has not been able to produce adequate milk to satisfy this demand, mainly due to low productivity of dairy animals.
USAID’s Avansa Agrikultura Project is a horticulture value chain activity aimed at addressing the key challenges of rural poverty, natural resource degradation, food insecurity, and under-nutrition.Through the promotion of sustainable production practices, increased functionality of farmer groups and associations, improved market linkages, and increased availability and access to quality agricultural inputs and services, including access to finance, the project will aim to stimulate and support increased economic activity and growth for Timorese citizensi
Cet article reprend des travaux de prospective réalisés sur l’Afrique de l’Ouest. Il souligne la tendance à l’augmentation de la taille et à la concentration des exploitations agricoles. Selon les auteurs, cette évolution nécessitera pour l’agriculture familiale une transition vers une vocation plus commerciale.
