The Islamic Republic of Afghanistan. Agro-Ecological Zoning Atlas. Part 1: Agro-climatic indicators

Agriculture is crucial for the national economy of the Islamic Republic of Afghanistan. Adoption of new strategies for agriculture monitoring, rural land use planning, and management are urgently required to reduce hunger and poverty and to assure sustainable food and feed production for future generations. The availability of reliable information on natural resources and agriculture for its monitoring and analysis is indispensable to the development and implementation of such strategies. For this purpose the project “Strengthening Afghanistan Institutions’ Capacity for the Assessment of Agriculture Production and Scenario Development” (GCP/AFG/087/EC), funded by the European Union (EU), is implemented by the Ministry of Agriculture, Irrigation and Livestock (MAIL) and the Food and Agriculture Organization of the United Nations (FAO). Within the context of this project, FAO and the International Institute for Applied Systems Analysis (IIASA) are developing a National Agro-Ecological Zoning activity (NAEZ) in Afghanistan. This Atlas is the first of two books and provides the collected information and maps of the country based on the agro-climatic Indicators

Afghanistan's Agro-ecological zoning atlas. Part 2: Agro-ecological assessments. First revision

Agriculture is crucial for the national economy of Afghanistan and in particularly so for the agriculturally dependent population which is constituting 60 percent of the total population. Adoption of new strategies for agriculture monitoring, rural land use planning and land management are urgently required to reduce hunger and poverty among rural population and to assure sustainable food and feed production for future generations. The availability of reliable information on natural resources and agriculture for its monitoring and analysis is indispensable to development and implementation of such strategies. However, productivity in the agricultural sector has been relatively low. Afghanistan has the potential to increase its output of cereals, fruits and vegetables. For this purpose, the project “Strengthening Afghanistan Institutions’ Capacity for the Assessment of Agriculture Production and Scenario Development” (GCP/AFG/087/EC), funded by the European Union, is implemented by the Ministry of Agriculture, Irrigation and Livestock (MAIL) and the Food and Agriculture Organization of the United Nations (FAO). Among the project objectives are improving the understanding of the country’s national resources endowment and limitations as well as assessing agricultural production capacities under current climatic conditions and likely impacts of climate change. Within the context of this project the Food and Agriculture Organization of the United Nations (FAO) and the International Institute for Applied Systems Analysis (IIASA) support and implement a National Agro-Ecological Zoning activity in Afghanistan (NAEZ) which assesses quality and availability of land resources and identifies crop cultivation potentials - suitable area, production and attainable yield - under prevailing soil and terrain conditions and for given current or future agroclimatic conditions. One of the outputs of the NAEZ activities is this Agro-Ecological Zones Atlas which is based on applications of the FAO/IIASA National Agro-Ecological Zoning system for current and future climates

Harmonized World Soil Database - HWSD (version 1.2)

HWSD-coverDuring discussions at the International Institute for Applied Systems Analysis (IIASA) in 1996, the need was identified for refinement of the agro-edaphic element of IIASA and FAO's Agro-Ecological Zones (AEZ) methodology then being used for IIASA’s "Modeling Land Use and Land Cover Change in Europe and Northern Eurasia (LUC)" project. An IIASA Interim Report was produced in 1997 detailing twenty soil attributes identified as being important for land evaluation, the analyses performed on existing databases, and methodologies for the development of taxotransfer rules to derive necessary data. Conclusions of this report were used for the analyses of that time, but the process that was born continued to develop into what would eventually become a separate product, the Harmonized World Soil Database. Between 2003 and 2006, IIASA and FAO sought out additional partners, including: - ISRIC-World Soil Information, together with FAO, were responsible for the development of regional soil and terrain databases and the WISE soil profile database; - the European Soil Bureau Network, which had recently completed a major update of soil information for Europe and northern Eurasia, and - the Institute of Soil Science, Chinese Academy of Sciences, which provided the recent 1:1,000,000 scale Soil Map of China. Vast volumes of recently collected regional and national updates of soil information collected by the partners were assimilated and harmonized by IIASA, where the HWSD raster, database, and viewer software were designed, implemented, and packaged for CD and web distribution into this state-of-the-art database. Version 1.0 was released in 2008. Since then, it has been updated with new information several times, has been used extensively around the world, and has recently been adopted by the Global Soil Partnership (GSP) as the definitive soil database at present, with plans for further updates made as part of the GSP process. The HWSD is of immediate use in the context of the Climate Change Convention and the Kyoto Protocol for soil carbon measurements and for the FAO/IIASA Global Agro-ecological Assessment studies (GAEZ 2012), for which HWSD was developed in the first place. The HWSD contributes sound scientific knowledge for planning sustainable expansion of agricultural production to achieve food security and provides information for national and international policymakers in addressing emerging problems of land competition for food production, bio-energy demand and threats to biodiversity. The HWSD is a 30 arc-second raster database with over 16000 different soil mapping units that combines existing regional and national updates of soil information worldwide (SOTER, ESD, Soil Map of China, WISE) with the information contained within the 1:5 000 000 scale FAO-UNESCO Soil Map of the World (FAO, 19711981). The resulting raster database consists of 21600 rows and 43200 columns, which are linked to harmonized soil property data. The use of a standardized structure allows for the linkage of the attribute data with the raster map to display or query the composition in terms of soil units and the characterization of selected soil parameters (organic Carbon, pH, water storage capacity, soil depth, cation exchange capacity of the soil and the clay fraction, total exchangeable nutrients, lime and gypsum contents, sodium exchange percentage, salinity, textural class and granulometry). Reliability of the information contained in the database is variable: the parts of the database that still make use of the Soil Map of the World such as North America, Australia, West Africa and South Asia are considered less reliable, while most of the areas covered by SOTER databases are considered to have the highest reliability (Central and Southern Africa, Latin America and the Caribbean, Central and Eastern Europe)

When enough should be enough: Improving the use of current agricultural lands could meet production demands and spare natural habitats in Brazil

Providing food and other products to a growing human population while safeguarding natural ecosystems and the provision of their services is a significant scientific, social and political challenge. With food demand likely to double over the next four decades, anthropization is already driving climate change and is the principal force behind species extinction, among other environmental impacts. The sustainable intensification of production on current agricultural lands has been suggested as a key solution to the competition for land between agriculture and natural ecosystems. However, few investigations have shown the extent to which these lands can meet projected demands while considering biophysical constraints. Here we investigate the improved use of existing agricultural lands and present insights into avoiding future competition for land. We focus on Brazil, a country projected to experience the largest increase in agricultural production over the next four decades and the richest nation in terrestrial carbon and biodiversity. Using various models and climatic datasets, we produced the first estimate of the carrying capacity of Brazil's 115 million hectares of cultivated pasturelands. We then investigated if the improved use of cultivated pasturelands would free enough land for the expansion of meat, crops, wood and biofuel, respecting biophysical constraints (i.e., terrain, climate) and including climate change impacts. We found that the current productivity of Brazilian cultivated pasturelands is 32–34% of its potential and that increasing productivity to 49–52% of the potential would suffice to meet demands for meat, crops, wood products and biofuels until at least 2040, without further conversion of natural ecosystems. As a result up to 14.3 Gt CO2 Eq could be mitigated. The fact that the country poised to undergo the largest expansion of agricultural production over the coming decades can do so without further conversion of natural habitats provokes the question whether the same can be true in other regional contexts and, ultimately, at the global scale

New generation of hydraulic pedotransfer functions for Europe

A range of continental-scale soil datasets exists in Europe with different spatial representation and based on different principles. We developed comprehensive pedotransfer functions (PTFs) for applications principally on spatial datasets with continental coverage. The PTF development included the prediction of soil water retention at various matric potentials and prediction of parameters to characterize soil moisture retention and the hydraulic conductivity curve (MRC and HCC) of European soils. We developed PTFs with a hierarchical approach, determined by the input requirements. The PTFs were derived by using three statistical methods: (i) linear regression where there were quantitative input variables, (ii) a regression tree for qualitative, quantitative and mixed types of information and (iii) mean statistics of developer-defined soil groups (class PTF) when only qualitative input parameters were available. Data of the recently established European Hydropedological Data Inventory (EU-HYDI), which holds the most comprehensive geographical and thematic coverage of hydro-pedological data in Europe, were used to train and test the PTFs. The applied modelling techniques and the EU-HYDI allowed the development of hydraulic PTFs that are more reliable and applicable for a greater variety of input parameters than those previously available for Europe. Therefore the new set of PTFs offers tailored advanced tools for a wide range of applications in the continent

Potential impacts on ecosystem services of land use transitions to second-generation bioenergy crops in GB

We present the first assessment of the impact of land use change (LUC) to second-generation (2G) bioenergy crops on ecosystem services (ES) resolved spatially for Great Britain (GB). A systematic approach was used to assess available evidence on the impacts of LUC from arable, semi-improved grassland or woodland/forest, to 2G bioenergy crops, for which a quantitative ‘threat matrix’ was developed. The threat matrix was used to estimate potential impacts of transitions to either Miscanthus, short-rotation coppice (SRC, willow and poplar) or short-rotation forestry (SRF). The ES effects were found to be largely dependent on previous land uses rather than the choice of 2G crop when assessing the technical potential of available biomass with a transition from arable crops resulting in the most positive effect on ES. Combining these data with constraint masks and available land for SRC and Miscanthus (SRF omitted from this stage due to lack of data), south-west and north-west England were identified as areas where Miscanthus and SRC could be grown, respectively, with favourable combinations of economic viability, carbon sequestration, high yield and positive ES benefits. This study also suggests that not all prospective planting of Miscanthus and SRC can be allocated to agricultural land class (ALC) ALC 3 and ALC 4 and suitable areas of ALC 5 are only minimally available. Beneficial impacts were found on 146 583 and 71 890 ha when planting Miscanthus or SRC, respectively, under baseline planting conditions rising to 293 247 and 91 318 ha, respectively, under 2020 planting scenarios. The results provide an insight into the interplay between land availability, original land uses, bioenergy crop type and yield in determining overall positive or negative impacts of bioenergy cropping on ecosystems services and go some way towards developing a framework for quantifying wider ES impacts of this important LUC
