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.

The increasing number of Jakarta Special Province residents further increased the amount of land required for daily usages. In order to maintain and improve the economy, agricultural land-use continued to be converted into non-agricultural land-use. The reduced amount of agricultural land-use was able to increase the population pressure on said land, surpassing the land carrying capability. Analyzing the remaining land resources of Jakarta Special Province aimed to understand the changes in land-use, land carrying capability, the scale of land resources, and to determine the population pressure of the residents of Jakarta Special Province. The methods used in this analysis was to use secondary data, presented in the form of tables, graphs, and maps, as well as quantitative and qualitative descriptive analysis. In general, Jakarta Special Province had experienced a conversion of agricultural land-use into non-agricultural land-use (e.g. residential and industrial) between the year 2010 to 2018. The number of residents had exceeded the carrying capacity of Jakarta’s land. This resulted from a growing need for non-agricultural land as well as the amount of population pressure, causing the unmet settlement needs.

Rural settlements in mountainous regions are a typical process that occurs in many places around the world and have a number of implications on the landscape. Among them is a threat it possesses to the conservation and management of Afromontane ecosystems. This study assessed the socio-economic factors that drive the changes in land use and forest cover and the extent of land use and vegetation cover in and around Magamba Nature Reserve. Focus group discussion, direct field observation and household survey were used to acquire socio-economic information that impacts land use and forest cover. Through the use of Remote Sensing and GIS methods Landsat satellite images of 1995, 2008 and 2015 were employed to identify the extent of the changes in land use and forest cover. The perceived factors for the changes include education level, unemployment, landless/limited, landholding, population pressure, expansion of built-up areas and agricultural land at the expense of other land covers. This study revealed the transformation of natural forest and associated vegetation from one form to another. There was a decrease in natural vegetation from 61.06% in 1995 to 26.02% in 2015 and increase in built-up areas by 6.69% and agricultural areas by 4.70%. This study recommends conservation monitoring and strong law enforcement relating to natural resources so as to promote sustainable use of resources to rescue the diminishing ecosystem services.

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.
