TL;DR: In this article, the authors track some of the major myths on driving forces of land cover change and propose alternative pathways of change that are better supported by case study evidence, concluding that neither population nor poverty alone constitute the sole and major underlying causes of land-cover change worldwide.
Abstract: Common understanding of the causes of land-use and land-cover change is dominated by simplifications which, in turn, underlie many environment-development policies. This article tracks some of the major myths on driving forces of land-cover change and proposes alternative pathways of change that are better supported by case study evidence. Cases reviewed support the conclusion that neither population nor poverty alone constitute the sole and major underlying causes of land-cover change worldwide. Rather, peoples’ responses to economic opportunities, as mediated by institutional factors, drive land-cover changes. Opportunities and

TL;DR: In this paper, the authors revisited flooding problems in Ibadan Metropolis, in the past fifty years, especially the most recent flood of August 2011, and found that 26,553 buildings were constructed within the statutory set back to the rivers and streams while 2,105 were flooded.
Abstract: This paper revisits flooding problems in Ibadan Metropolis, in the past fifty years, especially the most recent flood of August 2011. Flood disasters can be attributed to the unnecessary risks people take when they encroach on flood plains. There will be no flood disasters if human beings stayed away from the flood plains. The methodology adopted for the flood investigations includes site visits, interviews of affected inhabitants, and analyses of flood data collected during the field investigations. These investigations were complemented with review of past records of flooding, and interpretation of satellite imagery of flood affected areas, especially for inaccessible areas, to produce flood hazard maps. Results of the spatial analysis of flooding in the 11 local government areas of Ibadan indicate that 26,553 buildings were constructed within the statutory set back to the rivers and streams while 2,105 were flooded. Large scale encroachment into the river floodplains was observed throughout the area. The major cause of flooding in Ibadan Metropolis is due to uncontrolled urbanization of the area. The Nigerian Meteorological Agency (NIMET) predicted that there will be very heavy rains and flooding in a number of states in Nigeria in 2012. In Oyo State, Ibadan is specifically mentioned as a city to experience flooding. This emphasises the urgent need to put in place measures to facilitate effective management of the anticipated floods to prevent the re-occurrence of the damage and losses of the 2011 disaster.

TL;DR: In this article, the authors highlight the complexity of land-use/cover change and propose a framework for a more general understanding of the issue, with emphasis on tropical regions, and argue that a systematic analysis of local-scale land use change studies, conducted over a range of timescales, helps to uncover general principles that provide an explanation and prediction of new land use changes.
Abstract: We highlight the complexity of land-use/cover change and propose a framework for a more general understanding of the issue, with emphasis on tropical regions. The review summarizes recent estimates on changes in cropland, agricultural intensification, tropical deforestation, pasture expansion, and urbanization and identifies the still unmeasured land-cover changes. Climate-driven land-cover modifications interact with land-use changes. Land-use change is driven by synergetic factor combinations of resource scarcity leading to an increase in the pressure of production on resources, changing opportunities created by markets, outside policy intervention, loss of adaptive capacity, and changes in social organization and attitudes. The changes in ecosystem goods and services that result from land-use change feed back on the drivers of land-use change. A restricted set of dominant pathways of land-use change is identified. Land-use change can be understood using the concepts of complex adaptive systems and transitions. Integrated, place-based research on land-use/land-cover change requires a combination of the agent-based systems and narrative perspectives of understanding. We argue in this paper that a systematic analysis of local-scale land-use change studies, conducted over a range of timescales, helps to uncover general principles that provide an explanation and prediction of new land-use changes.

TL;DR: The Millennium Ecosystem Assessment (MEA) as discussed by the authors is a conceptual framework for analysis and decision-making of ecosystems and human well-being that was developed through interactions among the experts involved in the MA as well as stakeholders who will use its findings.
Abstract: This first report of the Millennium Ecosystem Assessment describes the conceptual framework that is being used in the MA. It is not a formal assessment of the literature, but rather a scientifically informed presentation of the choices made by the assessment team in structuring the analysis and framing the issues. The conceptual framework elaborated in this report describes the approach and assumptions that will underlie the analysis conducted in the Millennium Ecosystem Assessment. The framework was developed through interactions among the experts involved in the MA as well as stakeholders who will use its findings. It represents one means of examining the linkages between ecosystems and human well-being that is both scientifically credible and relevant to decision-makers. This framework for analysis and decision-making should be of use to a wide array of individuals and institutions in government, the private sector, and civil society that seek to incorporate considerations of ecosystem services in their assessments, plans, and actions.

TL;DR: A global-scale assessment of intensification prospects from closing ‘yield gaps’, the spatial patterns of agricultural management practices and yield limitation, and the management changes that may be necessary to achieve increased yields finds that global yield variability is heavily controlled by fertilizer use, irrigation and climate.
Abstract: In the coming decades, a crucial challenge for humanity will be meeting future food demands without undermining further the integrity of the Earth’s environmental systems1, 2, 3, 4, 5, 6. Agricultural systems are already major forces of global environmental degradation4, 7, but population growth and increasing consumption of calorie- and meat-intensive diets are expected to roughly double human food demand by 2050 (ref. 3). Responding to these pressures, there is increasing focus on ‘sustainable intensification’ as a means to increase yields on underperforming landscapes while simultaneously decreasing the environmental impacts of agricultural systems2, 3, 4, 8, 9, 10, 11. However, it is unclear what such efforts might entail for the future of global agricultural landscapes. Here we present a global-scale assessment of intensification prospects from closing ‘yield gaps’ (differences between observed yields and those attainable in a given region), the spatial patterns of agricultural management practices and yield limitation, and the management changes that may be necessary to achieve increased yields. We find that global yield variability is heavily controlled by fertilizer use, irrigation and climate. Large production increases (45% to 70% for most crops) are possible from closing yield gaps to 100% of attainable yields, and the changes to management practices that are needed to close yield gaps vary considerably by region and current intensity. Furthermore, we find that there are large opportunities to reduce the environmental impact of agriculture by eliminating nutrient overuse, while still allowing an approximately 30% increase in production of major cereals (maize, wheat and rice). Meeting the food security and sustainability challenges of the coming decades is possible, but will require considerable changes in nutrient and water management.
