ArticleJournal articleModeling CO2 restoration potential of mangrove ecosystems in Pakistan to support urban green spaces and human well-being

No results found.Abstract: Pakistan is facing major climate change challenges since in recent years, the annual mean temperature has increased by 0.5°C in the country. Karachi is the largest city and highly vulnerable to fatal heatwave events trolling maximum deaths and illness in recent years. Coast of Mangrove Forest (MF) plays an important role in daily temperature, local environment, and microclimatic conditions. It is a well-established scientific reality that carbon traps heat in the air, and now observing a dramatic rise in temperature. The study aimed to evaluate the vulnerability of the communities to heat-stress, and categorize the role of Mangrove Ecosystem Services to mitigate future disasters. Coupled models and GIS/RS tools were used to estimate the suitability of MF land-cover to categorize the latent status. Heatwaves during summer for three days were calibrated by the models which resulted that an inundation of CO2 stress factors, 250 (S-u=1.0) with a rise in temperature up to 44°C with 70% humidity causes more deaths under heat-periods. Our results linked heatwaves with climate warming and extreme weather events, aggravated by rapid urbanization, industrialization, deforestation, emission of CO2, degradation of MF, and land-use change. Moreover, findings revealed that there is a significant drop-off in urban greenspaces and growth in built-up areas during 1984-2016. In addition, the SILVA-model projected that MF around the city has the ability to absorb CO2 emission up to 55.4 million tons. SILVA-growth projected that 43.61% CO2 stock can be deposited by MF which contributes 19% of the ecosystem. Model showcase that rehabilitation of 30-mangrove trees per/100m2 possibly reduce the extreme tide of heat stress, tsunami, CO2, and improve the air-quality index of the city. This study provides initial assessment and policy directions to rehabilitate MF to promote sustainable cities and societies.

Book (series)FlagshipThe State of Food Security and Nutrition in the World 2020
Transforming food systems for affordable healthy diets
2020Updates for many countries have made it possible to estimate hunger in the world with greater accuracy this year. In particular, newly accessible data enabled the revision of the entire series of undernourishment estimates for China back to 2000, resulting in a substantial downward shift of the series of the number of undernourished in the world. Nevertheless, the revision confirms the trend reported in past editions: the number of people affected by hunger globally has been slowly on the rise since 2014. The report also shows that the burden of malnutrition in all its forms continues to be a challenge. There has been some progress for child stunting, low birthweight and exclusive breastfeeding, but at a pace that is still too slow. Childhood overweight is not improving and adult obesity is on the rise in all regions.The report complements the usual assessment of food security and nutrition with projections of what the world may look like in 2030, if trends of the last decade continue. Projections show that the world is not on track to achieve Zero Hunger by 2030 and, despite some progress, most indicators are also not on track to meet global nutrition targets. The food security and nutritional status of the most vulnerable population groups is likely to deteriorate further due to the health and socio economic impacts of the COVID-19 pandemic.The report puts a spotlight on diet quality as a critical link between food security and nutrition. Meeting SDG 2 targets will only be possible if people have enough food to eat and if what they are eating is nutritious and affordable. The report also introduces new analysis of the cost and affordability of healthy diets around the world, by region and in different development contexts. It presents valuations of the health and climate-change costs associated with current food consumption patterns, as well as the potential cost savings if food consumption patterns were to shift towards healthy diets that include sustainability considerations. The report then concludes with a discussion of the policies and strategies to transform food systems to ensure affordable healthy diets, as part of the required efforts to end both hunger and all forms of malnutrition. -
BookletCorporate general interestEmissions due to agriculture
Global, regional and country trends 2000–2018
2021Also available in:
No results found.The FAOSTAT emissions database is composed of several data domains covering the categories of the IPCC Agriculture, Forestry and Other Land Use (AFOLU) sector of the national GHG inventory. Energy use in agriculture is additionally included as relevant to emissions from agriculture as an economic production sector under the ISIC A statistical classification, though recognizing that, in terms of IPCC, they are instead part of the Energy sector of the national GHG inventory. FAO emissions estimates are available over the period 1961–2018 for agriculture production processes from crop and livestock activities. Land use emissions and removals are generally available only for the period 1990–2019. This analytical brief focuses on overall trends over the period 2000–2018. -

No results found.The SWSR is a reference document on the status of global soil resources that provides regional assessments of soil change. The information is based on peer-reviewed scientific literature, complemented with expert knowledge and project outputs. It provides a description and a ranking of ten major soil threats that endanger ecosystem functions, goods and services globally and in each region separately. Additionally, it describes direct and indirect pressures on soils and ways and means to combat s oil degradation. The report contains a Synthesis report for policy makers that summarizes its findings, conclusions and recommendations.The full report has been divided into sections and individual chapters for ease of downloading:
