The objectives of the research include; to examine the demographic characteristics of people living in Kwali Area Council; the causes of population increase in the area; to show the trends of agricultural productivity between 2007 -2016; to examine the relationship between population increase and agricultural productivity in the study area, as well as the effect of population change on agricultural productivity in the area. Data was sourced from both primary and secondary sources. Questionnaire was the major source of data while respondents were selected through systematic sampling technique. The data was analyzed using descriptive statistics such as frequency tables, percentages and charts among others graphs. Relationships were tested using the student T-test. The findings reveal that there exists a consistent increase in population size leading to the decline in agricultural productivity in the study area. Illiteracy, high fertility, improved medical facilities, presence of industries and basic amenities as well as good security network over the years were found to be the main reasons behind the increase in population. Some of the problems identified and threatening the existence of the area include; loss of agricultural land which led to decrease in food supply, hunger and poverty. Recommendations were proffered which include; placing restriction and curbing migration into the study area to check population as well as enforcing sanctions on land use abusers that convert agricultural lands to other land use in Kwali Area Council.

INTRODUCTION Annually, states in Nigeria encounter a massive loss of arable farmland caused by erosion as a result of heavy precipitation. In lined with this, prolonged drought and the pressure of animals grazing on the land is on its daily increase in the northern deserts while in the Niger delta region, oil spill and severe land degradation daily pollutes and renders hectares of arable farmlands infertile and this 135| Page 30 April 2019 www.gjar.org Vol-6, Issue-4 Global Journal of Advanced Research contributes immensely to about 80% of loss of biological diversity (Chakir, 2010). The rise in population has resulted in marginal rainfall areas being vulnerable to drought and more bare lands as a result of the decline in vegetative cover resulting from the intensive anthropogenic activities by humans, higher rates of animal grazing, deforestation for building and fuel needs, thereby exposing the soil to the ravages of wind and water erosion (Chakir, 2010). The high rate of population growth in Nigeria has resulted in the unsustainable use of natural resources which is the basic foundation for livelihood without having concern for the future. This has led to tremendous effects on our natural ecosystem. The provisioning, regulatory, cultural and supporting services which are derived from the ecosystem are put at a high risk due to the harsh use of these natural resources (Allen, 2014). Over the years, there have been several symptoms of ecological stress like the deteriorating nature of the grass land areas, very low crop yield, soil erosion which has forced so many migration activities to the cities and low standard of living by the poor. All these effects can produce long-term, possibly permanent damage to the environment which in turn would have a huge negative effect on agricultural production in Kwali Area Council (Wassmer, 2012). Kwali Area Council land is now being converted to other uses such as residential to meet the housing demand of the increasing population as well as commercial and industrial functions. The 200-2006 demolition exercise carried out by Mallam Nasir El-rufai, the then minister of the FCT forced lots of people to relocate from the city centers to its suburban in which Kwali was not left out. These created pressure on available resources in Kwali Area Council and led to reduction of farm sizes and consequently decline in the volume of agricultural products (Ejaro, 2013). 2. THE STUDY AREA Kwali is situated on the south-eastern wings of the FCT. It is located within latitude 08o10’ North and 08o49’ North and longitude 07o03’ East. Kwali is bounded by the Sukuku mountain ranges to the south and east. River Gurara to the west, and river Usman to the North. It is located at about 74km drive to the FCT centre, with a total land mass of about 1,206 kilometer square (National Population Commission (NPC), 2016). Kwali Area Council is also bounded to the North by Gwagwalada Area Council, South by Abaji Area Council, East by Kuje Area Council and west by Suleja Hills, the land area translates to about 4,850 hectares (Ejaro, 2013).

LITERATURE REVIEW 3.1 Concept of Agricultural Productivity Agricultural productivity is measured as the ratio of agricultural outputs to agricultural inputs. Agricultural productivity is not a synonym of fertility. It is generally use to express the power of agriculture in a particular region to produce crops without regard to whether that power is due to the bounty of nature or to the efforts of the man. Productivity like disparity is a relative concept. The term productivity has been used in different meanings and has aroused many conflicting interpretations. Some time it is considered as the overall efficiency with which a production system works, while others it is defined as a ratio of output to resources expended separately, or collectively. This term has also incorrectly and interchangeably been used with production. In reality, production refers to the volume of output while productivity signifies the output in relation to resource expended. Production can be increased by employing more resources without increasing productivity. On the other hand, productivity can be increased without increasing production by employing less input for the same production level. But it is commonly agreed that productivity is the ability of a production system to produce more economically and efficiently. Therefore, agricultural productivity can be defined as a measure of efficiency with which an agricultural production system employs land, labour, capital and other resources. In recent years many attempt have been made to define the connotation of agricultural productivity (Ildephonse, 2016). Daniel (2015) explains it as, “Productivity expresses the varying relationship between agricultural output and one of the major inputs, like land or labour or capital, other complimentary factors remaining the same...” It may be born in mind that productivity is physical rather than a value concept. The connotation of agricultural productivity engaged the attention of many an economist at the 23rd annual conference of the Indian society of agricultural economics, some economists suggested that the yield per acre should be considered to indicate agricultural productivity. A number of objections were raised against this view because it considered only land which is just one factor of production while other factors are also responsible, and therefore it was arbitrary to attribute productivity entirely to land and express it per acre of land. It was suggested, for instance, that productivity could also be measured in terms of per unit of labor and 137| Page 30 April 2019 www.gjar.org Vol-6, Issue-4 Global Journal of Advanced Research different regions compared on that basis. After a thorough discussion, it was generally agreed that the yield per acre may be considered to represent the agricultural productivity in a particular region and that other factors of production be considered as the possible cause for the variation while comparing it with the other regions (Daniel, 2015). Ildephonse (2016) has expressed the connotation of productivity in these wards.” Productivity is defined in economics as the output per unit of input… the art of securing an increase in output from some input or of getting the same output from a smaller input.” He further suggests that increases in productivity, Whether in industry or agriculture, is generally the result of a more efficient use of some or all the factors of production, viz. land,labour and capital Saxon incorporates the productivity as a physical relationship between output and the input which gives rise tothat output. Ildephonse (2016) considers productivity in broad terms, to denote the ratio of output to any or all associated inputs in real term. 3.2 Measurement of Agricultural Productivity The assessment of agricultural productivity has engaged the attention of scholars working in different disciplines like geography, economics and agricultural science for a land time; many attempts have been made to measure and quantify agricultural productivity in India as well as in other countries of the world. The measurement of agricultural productivity is not a simple task as it involves a relationship between inputs and outputs in agricultural production Input itself is a complex thing which governs farming efficiency.
