Climate change is a global environmental threat, affecting every sector of the economy with agriculture being the most affected as a result of its dependence on climate especially rainfall and temperature. The objective of this study is to examine the impacts of climate change on agriculture (crop production) and identify the farmers’ adaptation strategies to the impacts of climate change in Senegal. This study employed systematic literature review. Searching of relevant documents were conducted between 26th December 2020 and 10th February, 2021. A comprehensive search of six databases were conducted. The databases searched were Scopus, African Journal Online (AJOL), ProQuest, Elsevier, Research gate, and Google scholar. The findings revealed that temperature is expected to increase by median value of 0.90C (0.70C-1.50C) by 2035, by 2.10 (1.60C-3.30C) by 2065, and 4.00C (2.6-5.90C) by 2100 and rainfall could increase by 1% (uncertainty range of −4% to +8%) by 2035, 2% (−8% to +8%) by 2065, and 5% (−10% to +16%) by 2100. As a result of rising temperatures, local agricultural production will be less than 50kg per capita by 2050. This is expected to have an effect on crop imports as well as regional migration. The decrease in rainfall under RCP2.6, (Representative Concentration Pathway) combined with the effect of temperature, has a significant impact on the yield of sorghum, maize, and millet, with production decreasing by up to 20-50%. Farmers employed several adaptation strategies to adapt to the impacts of climate change; sowing improved variety, mixed cropping, income diversification, ownership of multiple farms, religious practices in form of prayer. The review recommends strengthening of climate related institutions, adoption of new innovations, implementation of new climate related policies, climate monitoring and forecasting, enhancing and strengthening community-based adaptation through sensitization and incentives.

This paper presents an overview of the current solid waste management practices in Gashua town and provides a brief discussion on future challenges. Gashua town the headquarters of Bade Local Government Area since 1949. Since then the population has mainly due to the influx of people and its strategic location along the axial route to significant towns in the state. Wastes are generated mainly from residential, commercial and institutional land uses. Waste collection sites are strategically situated as identified by the agency and designated as high waste generating points, metal waste bins and constructed waste bunkers. The contents of these bins are finally disposed of at a location 6kilometres away from the generating points. Spatial data on waste distribution was collected using a global positioning system (GPS). The data was manipulated and processed using a Geographic information system (GIS) to produce the waste distribution map. Findings revealed that the existing solid waste management system is inefficient as the present practice relies on monthly collection and disposal of waste using an open dumpsite.

ARCO and PERTAMINA, the Indonesian State Oil and Gas Company, produced gas from reserves in the Kangean Block, about 100 miles north of the island of Bali. The block areas covers approximately 4508 sq.km. of ocean and land, including 10 islands, and consists of 14 production wells, 30 exploratory wells, 2 gas processing trains, a harbour, an air strip and other support facilities. An estimated 225 miles of subsea and 45 miles of onshore pipelines deliver produced gas to customers. Potential environmental impacts of development and operations include affects on marine life, terrestrial function ecosystems and the atmosphere. The potential impact also exist on the socio and human environment. We used social cultural needs and government regulations issues is a main tool to minimize or prevent the impact and to avoid possible reversals and disturbance to the gas development and operation itself. These tools then effectively raise many ideas on how to protect, preserve, and develop or enhance environmental quality, to integrate the company policy and commitment, and to arrive at the decision making with involving all concerned individuals, groups, or organizations in Environmental Management System (EMS) planning, implementing, and monitoring steps. These processes produced a "Top - Down Strategy" to develop and operate the Kangean block area. In addition, the strategy also tends to produce a severe imbalance between gas development on the hand, and EMS implementation on the other. To overcome the problem, we used six structural components in the EMS for Kangean block: planning/policy, project assessment, implementation, technical rigor, consultation, and institutional integrity.
