The Government of Pakistan strongly supports public–private partnership (PPP) initiatives. From 1990 to 2019, Pakistan witnessed 108 financially closed PPP projects, with a total investment of approximately $28.4 billion. About 88% of these projects are in the energy sector, attracting more than $24.7billion, followed by investments in the port sector. In early 2021, Parliament approved the amendments to the 2017 PPP Law, enacting the Public Private Partnership Authority (Amendment) Act 2021. This further strengthens the enabling legal and regulatory framework for developing and implementing PPPs, thereby promoting private sector investment in public infrastructure and related services.
Work is constantly reshaped by technological progress. New ways of production are adopted, markets expand, and societies evolve. But some changes provoke more attention than others, in part due to the vast uncertainty involved in making predictions about the future. The 2019 World Development Report will study how the nature of work is changing as a result of advances in technology today. Technological progress disrupts existing systems. A new social contract is needed to smooth the transition and guard against rising inequality. Significant investments in human capital throughout a person’s lifecycle are vital to this effort. If workers are to stay competitive against machines they need to train or retool existing skills. A social protection system that includes a minimum basic level of protection for workers and citizens can complement new forms of employment. Improved private sector policies to encourage startup activity and competition can help countries compete in the digital age. Governments also need to ensure that firms pay their fair share of taxes, in part to fund this new social contract. The 2019 World Development Report presents an analysis of these issues based upon the available evidence.
Presents case studies resulting from participation in the World Bank by developing countries such as Chad, Brazil, and Nigeria
Jerry Thigpen's study on the history of the Combat Talon is the first effort to tell the story of this wonderfully capable machine. This weapons system has performed virtually every imaginable tactical event in the spectrum of conflict and by any measure is the most versatile C-130 derivative ever produced. First modified and sent to Southeast Asia (SEA) in 1966 to replace theater unconventional warfare (UW) assets that were limited in both lift capability and speed the Talon I quickly adapted to theater UW tasking including infiltration and resupply and psychological warfare operations into North Vietnam. After spending four years in SEA and maturing into a highly respected UW weapons system the Joint Chief of Staff (JCS) chose the Combat Talon to lead the night low-level raid on the North Vietnamese prison camp at Son Tay. Despite the outcome of the operation the Talon I cemented its reputation as the weapons system of choice for long-range clandestine operations. In the period following the Vietnam War United States Air Force (USAF) special operations gradually lost its political and financial support which was graphically demonstrated in the failed Desert One mission into Iran. Thanks to congressional supporters like Earl Hutto of Florida and Dan Daniel of Virginia funds for aircraft upgrades and military construction projects materialized to meet the ever-increasing threat to our nation. Under the leadership of such committed hard-driven officers as Brenci Uttaro Ferkes Meller and Thigpen the crew force became the most disciplined in our Air Force. It was capable of penetrating hostile airspace at night in a low-level mountainous environment covertly to execute any number of unconventional warfare missions.
This technical paper begins by introducing the concept of aquaponics, including a brief history of its development and its place within the larger category of soil-less culture and modern agriculture. It discusses the main theoretical concepts of aquaponics, including the nitrogen cycle and the nitrification process, the role of bacteria, and the concept of balancing an aquaponic unit. It then moves on to cover important considerations of water quality parameters, water testing, and water sourcing for aquaponics, as well as methods and theories of unit design, including the three main methods of aquaponic systems: media beds, nutrient film technique, and deep water culture. The publication discusses in detail the three groups of living organisms (bacteria, plants and fish) that make up the aquaponic ecosystem. It also presents management strategies and troubleshooting practices, as well as related topics, specifically highlighting local and sustainable sources of aquaponic inputs. The publication also includes nine appendixes that present other key topics: ideal conditions for common plants grown in aquaponics; chemical and biological controls of common pests and diseases including a compatible planting guide; common fish diseases and related symptoms, causes and remedies; tools to calculate the ammonia produced and biofiltration media required for a certain fish stocking density and amount of fish feed added; production of homemade fish feed; guidelines and considerations for establishing aquaponic units; a cost-benefit analysis of a small-scale, media bed aquaponic unit; a comprehensive guide to building small-scale versions of each of the three aquaponic methods; and a brief summary of this publication designed as a supplemental handout for outreach, extension and education.
In recent years, the humanitarian community has looked inward, learning from their past experiences in providing emergency shelter for the ever-increasing number of populations suffering from crises worldwide. The humanitarian reform process has helped widen the community of practitioners, reinforced global and country-based coordination systems, and required the agencies concerned to seek new and better means of ensuring integrated and robust humanitarian programming. This publication is an example of a series of learning tools being produced to support improved response to crises. It has been developed by the Emergency Shelter Cluster through a group of agencies within the cluster led by UN-HABITAT. It contains summaries of a range of experiences applied in crisis situations, and an honest appraisal of their successes and failures.
Focused on the dual aspects of access and quality, this publication discusses the role of textbooks in facilitating quality education for all. The book consists of reviews of the international perspectives as well as case studies on Brazil, Russian Federation, and Rwanda. It also documents strategies that could help to optimise procedures of textbook development, production, and evaluation; enhance textbooks' pedagogical impact; improve teachers' selection of textbooks; and raise textbook supply efficiently.
