Econometric and simulation analyses indicate that land degradation does not threaten agricultural productivity growth and food security at the global level, but problems exist in some areas. Improving market performance could reduce erosion-induced yield losses to 0.1 percent per year and the number of hungry people in less-developed countries by 5 percent over 10 years.

Ever since the oil, financial and food crises of 2008, sub-Saharan Africa has witnessed a marked increase in large-scale investment in agricultural land. The drivers of this investment are varied and include growing food, water and energy insecurity as well as social and economic interests of investors and recipient countries. The shape of these investments and their eventual outcomes are equally influenced by the existing land and water governance systems in the host countries.

Concerns about future food security in the face of volatile and potentially lower yields due to climate change have been at the heart of recent discussions on adaptation strategies in the agricultural sector. While there are a variety of studies trying to quantify the impact of climate change on yields, some of that literature also acknowledges the fact that these estimates are subject to substantial uncertainty. The question arises how such uncertainty will affect decision-making if ensuring food security is an explicit objective.

Population pressures and the need to optimize the use of limited available land has led to increasing cropping affluence levels within the maize agro-ecologies in Kenya, and a shift from large to smallholder intensification and multiple cropping patterns. Using a geographic information system, this study relates cropping patterns, by area share, maize productivity and household incomes across maize agro-ecologies, with the purpose to establish a decision support system for optimizing land allocation and in priority setting for introduction of new technologies such as Bt maize varieties.

Without support, the levels of agricultural public goods will fall short of the demand in high cost countries like Norway, Finland and Iceland. However, as demonstrated in this paper using Norway as a case, the current support and agricultural activity is far out of proportions from a public goods perspective. Model simulations show that at most 40% of the current support level can be defended by the public good argument. Furthermore, the present support, stimulating high production levels, is badly targeted at the public goods in question.

Vihiga, one of the poorest and densely populated districts in Kenya is perpetually food deficit (GOK, 2005). While food demand continued to rise, production fell behind both targeted production and district demand. To make matters worse food deficit situation worsened over the last decade. Rising population and competition for resources have curtailed efforts to improve household food production in the district. Unfavorable poverty indicators in the district only make matters worse.

Land has a cultural value in Nigeria in that its ownership cements
the relationship of the owner with the community. But more
importantly, land resource is critical to the livelihood of rural
farmers because they depend on it for income and food supply.
It is therefore important that it is sustainably managed and
efficiently used. This study investigated the ownership pattern
of land among the farming families in the study area and the
attitude towards its management. It adopted the farming and
