The study examined the relationship between agricultural land use and population growth rates from 1961 to 2018 in Nigeria. Secondary data were obtained from Food and Agricultural Organization and the World Bank. Descriptive statistics, trend equation and correlation analyses were used. Findings revealed that agricultural and arable land utilization grew at the rate of 0.62% and 0.72%, respectively per annum; while the total population growth rate stood at 2.57%. Also, urban and rural population grew at a rate of 4.75% and 1.67% respectively. In addition, the agricultural and arable land utilization rates had significant positive correlations with the total population, urban and rural population. Besides, the findings revealed that, agricultural land (to total land ratio) has continued to increase and currently averaged at 68.78% indicating massive land expansion put under agricultural used. Findings revealed that, most arable crop outputs increase majorly from land expansion rather than land productivity, a situation that cannot assure sustainable agricultural land use food security in a near future. Hence, the country needs agricultural land sparing policies and technologies to slow the current agricultural land expansion drive. Besides, the country’s agricultural land policies should focus on achieving land productivity and sustainable land-sharing strategies among major land users in the country. Again, the rural population growth rate is lower than the urban growth rate, implying that, the rural population is deteriorating with its probable negative effect on farm labour. This needs to be addressed urgently if the sustainable agricultural system is to be achieved in the near future in Nigeria.

This chapter asks whether evidence supports the widely held belief that land used for agriculture around the world has continued to rapidly expand via conversion of natural habitat in response to the demands created by recent human population growth. Contrary to conventional wisdom, global agricultural land use peaked in 1998 and has since declined. While habitat continues to be cleared for agriculture, on a global net basis, more agricultural land has been converted to other uses than vice versa. This analysis also found that national trends in agricultural expansion are driven by factors other than population growth. Although this does not mean agriculture is “sustainable,” these findings challenge the dominant narrative around global agricultural expansion and highlight other important issues that must be addressed. Looking at data at national and subnational scales is essential to understand the implications of global trends in agriculture, where improvements and interventions are most needed.

The Tehuacán-Cuicatlán Valley, Mexico, is the semiarid region with the richest biodiversity of North America and was recently recognized as a UNESCO's World Heritage site. Original agricultural practices remain to this day in agroforestry systems (AFS), which are expressions of high biocultural diversity. However, local people and researchers perceive a progressive decline both in natural ecosystems and AFS. To assess changes in location and extent of agricultural land use, we carried out a visual interpretation of very-high resolution imagery and field work, through which we identified AFS and conventional agricultural systems (CAS) from 1995 to 2003 and 2012. We analyzed five communities, representative of three main ecological and agricultural zones of the region. We assessed agricultural land use changes in relation to conspicuous landscape features (relief, rivers, roads, and human settlements). We found that natural ecosystems cover more than 85% of the territory in each community, and AFS represent 51% of all agricultural land. Establishment and permanence of agricultural lands were strongly influenced by gentle slopes and the existence of roads. Contrary to what we expected, we recorded agricultural areas being abandoned, thus favoring the regeneration of natural ecosystems, as well as a 9% increase of AFS over CAS. Agriculture is concentrated near human settlements. Most of the studied territories are meant to preserve natural ecosystems, and traditional AFS practices are being recovered for biocultural conservation.

Farmer Decision Making

Agricultural land-use change is a dynamic process that varies as a function of social, economic and environmental factors spanning from the local to the global scale. The cumulative regional impacts of these factors on land use adoption decisions by farmers are neither well accounted for nor reflected in agricultural land use planning. We present an innovative spatially explicit agent-based modelling approach (Crop GIS-ABM) that accounts for factors involved in farmer decision making on new irrigation adoption to enable land-use predictions and exploration. The model was designed using a participatory approach, capturing stakeholder insights in a conceptual model of farmer decisions. We demonstrate a case study of the factors influencing the uptake of new irrigation infrastructure and land use in Tasmania, Australia. The model demonstrates how irrigated land-use expansion promotes the diffusion of alternative crops in the region, as well as how coupled social, biophysical and environmental conditions play an important role in crop selection. Our study shows that agricultural land use reflected the evolution of multiple simultaneous interacting biophysical and socio-economic drivers, including soil and climate type, crop and commodity prices, and the accumulated effects of interactive decisions of farmers.
