Scaling Success: Lessons from Adaptation Pilots in the Rainfed Regions of India
"Scaling Success" examines how agricultural communities are adapting to the challenges posed by climate change through the lens of India's rainfed agriculture regions. Rainfed agriculture currently occupies 58 percent of India's cultivated land and accounts for up to 40 percent of its total food production. However, these regions face potential production losses of more than $200 billion USD in rice, wheat, and maize by 2050 due to the effects of climate change. Unless action is taken soon at a large scale, farmers will see sharp decreases in revenue and yields.Rainfed regions across the globe have been an important focus for the first generation of adaptation projects, but to date, few have achieved a scale that can be truly transformational. Drawing on lessons learnt from 21 case studies of rainfed agriculture interventions, the report provides guidance on how to design, fund and support adaptation projects that can achieve scale
Pediatric Idiopathic Intracranial Hypertension
Our understanding of pediatric IIH has been refined since Dr. Lessell's review in 1992. Recent studies use of rigorous methodologies and standard definitions has elucidated distinct demographic trends. Specifically, the incidence of IIH seems to be increasing among adolescent children, and within older children its clinical picture is similar to that of adult IIH
Mainstreaming Photo- and Video-Based Documentation as Method for Establishing a Level of Service Framework for the Mumbai Suburban Railway System
The city of Mumbai has grown at an unprecedented rate, increasing the burden of mobility on its core public transport system, the Mumbai suburban railway network. The system is likely failing from “over-optimization,” with stations not designed to cater to the needs of a rapidly growing city, which has led to a steady surge in fatalities over the years, primarily in the metropolitan region beyond the city limits. Besides fatalities, research indicates that crowding has led to extreme fear and insecurity, especially in women and young commuters, with inappropriate behavior by fellow passengers causing them extreme discomfort. There is a need to decongest the Mumbai suburban rail network across the system and to gain a better measure of the extent of crowding in and around transit facilities. Concepts such as level of service (LOS) from the vantage point of crowding science can be used to address this need. However, there are two critical challenges. First, concepts developed in the Global North are inadequate to deal with the kind of commuter densities and complexities typical of cities like Mumbai. Secondly, conventional data gathering methods have proved to be time consuming, costly, and too inflexible to capture dynamic commuter behavior critical to the science of crowd management. This paper aims to address these two challenges by articulating a set of “inquiries” that can inform a localized framework and share learnings from the application of basic video and image processing. Thus, it proposes dynamic data capture methods that inform and enable a scientific planning process
Urban Dynamics for Environmental Action
Urban growth and urbanization processes have accelerated globally, especially in the last 45 years (United Nations Population Fund [UNFPA] 2007; United Nations 2019a).
This has improved the quality of life of many people. Urban
life provides some groups with access to better jobs, better
services like drinking water and sanitation, better education,
housing and health care, resulting in longer life expectancies
(Vardoulakis and Kinney 2019). For others, however, urban
life is characterized by the challenges of poverty and
inequality, congestion, poor health and feelings of isolation or
dislocation. Significant portions of the urban population still
struggle to access the basic services required for a dignified
human life (Satterthwaite et al. 2020) and feel trapped within
harsh living conditions. At the same time, urbanization, along
with biodiversity loss, ecosystem degradation and pollution,
are central drivers of environmental change (United Nations
2019b and see chapter 3). As highlighted in the GEO-6 report,
urban inequality and environmental sustainability are deeply
intertwined. This report argues, so are their solutions.
This chapter, along with chapter 3, sets out the context
through which deep urban transformation objectives and
pathways can be understood. It outlines the deeply rooted and
persistent challenges of inequality, pollution, environmental
degradation, resource depletion and biodiversity loss faced
by the majority of cities. All these problems have intensified
in recent decades, despite global, national and local efforts
to facilitate sustainable urban transitions. Rising to the
challenge of necessary urban transformations first requires
us to identify and understand these persistent challenges,
referred to here as “lock-ins”. For the purposes of this chapter
this term is defined as complex, structural barriers that are
deeply rooted in the political economy and the governance
web particular to each city and that, combined, contribute to
”business-as-usual” urban planning visions and practices.
Effectively, lock-ins refer to sociopolitical and behavioral
processes that lead to physical lock-ins of energy use and
carbon emissions in built infrastructure and urban form,
biodiversity loss, ecosystem degradation and pollution. This
interconnected set of lock-ins is ultimately slowing down
the pace of urban transformation.
This account of the systemic failures to deliver
transformation – or at the very least to slow the pace of
change in most cities (section 2.3) – is developed after a
description of larger global urbanization trends (section 2.2).
These trends include the diversity of cities and urban areas
in terms of population, size, urbanization, their relationship to
the environment and ecosystems, and their varying capacities
to respond to the growing and interconnected challenges
of urbanization in the twenty-first century. In particular,
many of the rapidly urbanizing cities of the Global South are
poorly equipped to deal with these challenges. They are also
the most affected by deepening inequality, the impacts of
climate change and environmental degradation. Most cities
are currently on unsustainable trajectories. This contributes
to multiple dimensions of ecological, social and economic
damage, although this can take different forms, with different impacts and in ways that are yet to be fully grasped.
Finally, the chapter explores ways in which a growing
number of cities are already experimenting with
transformative actions to overcome intersecting sociopolitical,
behavioural and physical lock-ins, positioning
them as drivers of environmentally sustainable, low-carbon,
resilient, healthy and inclusive futures (section 2.4). This
section shows that disruption to “business as usual” can
occur on different scales, can come from multiple sources
and agents, and is often pioneered by singular, even small
catalytic actions, as is explained in more detail in chapter
5. However, for the large-scale systemic change that is
urgently called for and described in chapter 4 to happen,
local authorities and urban communities will need support
and must share risks beyond their boundaries. Setting and
maintaining cities on transformative pathways will mean
reinforcing networks of learning and support, from the level
of key communities all the way to national governments
