The sluggish increase in the area productivity of staple crops is a major factor causing increased dependence of African countries on food imports. The increased use of mineral fertiliser may dramatically improve the food balance of many countries and result in lower food prices, higher food supply and consumption, and improved food security and nutritional status. In Benin, West Africa, political measures to improve farmers' access to fertiliser are biased in favour of cotton production.

Spatio-temporal dynamics of pastoral grazing resources influences the pastoral production system. Obtaining timely and reliable information on the status of these resources will support planning and early response to climatic variability.

Study on household food security is very essential now that Nigeria is currently facing the problem of food crisis. This study presents findings on household food security in the North Central Nigeria (NCN). The first objective was to review and highlight the commonly used measures of households' food security with their pros and cons; second, to determine the food security status of households; and third, to analyse the determinants of household food security status in the study area.

Large-scale irrigation schemes have not yielded the expected outcomes in Sub-Saharan Africa. In Mauritania, average land productivity of rice schemes lies between 3 and 3.5tha⁻¹ and irrigated land has progressively being abandoned. At the same time, there is new international attention towards interventions in large-scale irrigation in the Sahel. Spatial and temporal variability of production are main causes of low productivity of large-scale irrigation schemes in Mauritania and threats to their sustainability.

Safe and sustainable management of waste presents a major challenge in cities in the Global South. For decades farmers in the peri-urban interface (PUI) have used biodegradable components of urban waste as inputs into their farming practices. Evidence from Kano, Nigeria; Kumasi, Ghana; Hubli-Dharwad and Kolkata, India reveals in rare detail how urban waste reuse plays an important role in the livelihood strategies of lower-income families nd while waste farming also contributes significantly to urban food security.

During 2008 the world witnessed a global food crisis which caused social unrest in many countries and drove 75 million more people into poverty. The crisis resulted from sharply higher oil prices, increased bio-fuel production, dwindling grain stocks, market speculation, changing food consumption patterns in emerging economies, and changes in world trade agreements, among other factors. Although the rise in food prices was sudden, the fragility of global food security had been developing for years.

The social and economic consequences of horticultural product food losses from farm to the consumer remain unacceptably high. In developing countries postharvest losses compromise food security, income generation and poverty alleviation for millions of families. In developed countries substantial product losses result in economic losses to supply chain participants and reduced supplies of healthy products into international markets.

Botanical capacity plays a fundamental role in solving the grand challenges of the next century, including climate change, sustainability, food security, preservation of ecosystem services, conservation of threatened species, and control of invasive species. Yet critical components of botanical education, research, and management are lacking across government, academic, and private sectors.

For the last 50 years, local, state and the federal governments have expressed concerns about farmland retention. Four benefits have been used to warrant farmland preservation programs: food security and local food supply, viable local agricultural economy, environmental and rural amenities, and sound fiscal policy and orderly development. We explore the available evidence of how well farmland preservation programs have provided these benefits.

The growth of private investment in developing‐country agriculture, new advances in the biological sciences, and rapid integration of developing countries into the global trading system has heightened interest in the topic of seed market and intellectual property rights’ (IPRs) policies among public policy‐makers, corporate decision‐makers and other actors in the agricultural sector.

Land-use patterns are influenced by both top-down and bottom-up (local) factors, with their interactions varying in both space and time. This provides a major challenge to decision-making for sustainable multifunctional landscapes. A cross-scale scenario structure has been developed to integrate top-down and bottom-up context based upon the familiar IPCC Special Report on Emission Scenarios framework.
