Land Tenure Systems and Agricultural Productivity in Gombe Nigeria

The purpose of this study is to examine the existing land tenure systems in Gombe state Nigeria with a view to determining its impact on agricultural productivity in the study area. The targeted population for the study comprised of 7,832 households in purposively selected agrarian settlements cutting across the 3 senatorial districts in Gombe state Nigeria. The population was stratified into three zones and two locations were selected from each zone. The sample size for the study comprised of 500 households in each of the study locations. Hence, 500 questionnaires were administered on the household heads of the 6 study locations making a total of 3,000 questionnaires (representing 38.3% of the targeted population). However only 2,223 (74.1%) questionnaires were correctly filled and returned for analysis. The random sampling technique was adopted in the questionnaire administration. Descriptive statistical tools such as frequency counts, averages, weighted mean and percentages were used in analyzing the data obtained. The Relative Importance Index (RII) was used to identify and rank the variables. Inferential statistical tool such as multiple regressions were also used in analyzing the relationship between the criterion or dependent variable and the predictors or independent variables. The study revealed that customary land tenure system is the predominant type of tenure system (60.1%) practiced in the study area. Similarly, agricultural productivity in the study area was shown to be impeded by land tenure insecurity (RII, 0.933963), political/bureaucratic bottlenecks in land rights acquisition for agricultural purposes (0.846154) and tenure rules such as stipulated in the Nigerian Land Use Act of 1978 (RII, 0.65596) among others. The study also showed a strong positive relationship of 0.809 between land tenure systems and agricultural productivity in the study area. The study concluded that for better agricultural productivity in the study area in particular and similar developing economies in general, farmers need to have secured land tenure as this encourages investments in the secured land which consequently improves agricultural productivity.

A Theoretical Model for Ore Mining Waste Management with regard to Pollution of Food Webs in Water Bodies

Dam disasters occur sometimes frequently around the world as they did recently in 2015 and 2019 in Minas Gerais, Brazil. As a result, hundreds of families were displaced, and many cities suffered from water shortages. The study aimed to reduce ore mining waste pollutions in rivers and ocean currents and therefore mitigate their impact on the food webs. A model based on the equality principle named EUROPE (Efficient Use of Resources for Optimal Production Economy) was used to estimate shadow costs of economic systems. It was applied to ore mining wastes management in order to mitigate their negative impact on rivers and oceans. As a result, it gave a comprehensive picture of that management system in economic, technical as well as environmental terms.

Trichoderma: A Complete Tool Box for Climate Smart Agriculture

The green revolution practiced at a great cost of environment to meet the ever-increasing demands for food and fiber. The indiscriminate use of agrochemicals resulted in a damaged ecosystem, food and water contamination, lost of local cultivar, pesticide tolerance, and disease resistance along with different climate change vulnerability. All these pressurize further on agricultural system to increase its productivity. Short-termed chemical remedy turns into today's hot topics of both environment and health concern. There is an urgent need to develop a sustainable approach for maximum crop production with minimum damage in climate vulnerable zone. Trichoderma are eco-friendly bio-reliance similar to organic and integrated management (IPM) recognized globally. In Bangladesh, the time is to avail Trichoderma as substitute of agrochemicals and fertilizers to combat biotic, abiotic both stresses. This study is for searching beneficial arsenal of Trichoderma to discover the whole tool box to counteract climate threat in rising demand of crop.
