Ghana, África, África occidental
Including inland water bodies, Ghana covers 238,539 square kilometers and is located on the south central coast of West Africa. The country shares bor¬ders in the east with Togo, in the north with Burkina Faso, and in the west with Côte d’Ivoire. The topography of Ghana is mainly undulating, with most slopes less than 5 percent and many not exceeding 1 percent. The topography of the high rainforest is, however, mainly strongly rolling. The uplifted edges of the Voltarian basin give rise to narrow plateaus between 300 and 600 meters in elevation (Boateng 1998).

In Africa, where most agriculture is rainfed, crop growth is limited by water availability. Rainfall variability during a growing season generally translates into variability in crop production. While the seasonality of rainfall in the drier rangelands can play a significant role in productivity, rain-use efficiency (RUE)—the amount of biomass produced (in kilograms of dry matter per hectare) per millimeter of rainfall—also drives production.

Sustainable agricultural intensification holds promise to play a
role in the broader effort to ensure food security while protecting our natural
resource base. But what would such a sustainable intensification look like in
practice? This chapter presents the results of an ex ante assessment of the yield
and food security potential of 11 technologies for the sustainable intensification
of the key staple crops of maize, rice, and wheat.

Malnutrition costs the world trillions of dollars, but global commitment to improving people’s nutrition is on the rise, and so is our knowledge of how to do so. Over the past 50 years, understanding of nutrition has evolved beyond a narrow focus on hunger and famine. We now know that good nutrition depends not only on people’s access to a wide variety of foods, but also on the care they receive and the environment they live in. A number of countries and programs have exploited this new understanding to make enormous strides in nutrition.

Smallholder farmers have a vital role to play in global food security and nutrition, and in supporting a range of development and climate change goals. Strengthening the resilience and commercial viability of these farmers, particularly women and youth, can increase their capacity to contribute to these global goals.
