aboveground biomass mapping - airborne lidar - carbon - forest degradation - Indonesia - Kalimantan - peat swamp forests

The forests of Kalimantan are under severe pressure from extensive land use activities dominated by logging, palm oil plantations, and peatland fires. To implement the forest moratorium for mitigating greenhouse gas emissions, Indonesia's government requires information on the carbon stored in forests, including intact, degraded, secondary, and peat swamp forests. We developed a hybrid approach of producing a wall-to-wall map of the aboveground biomass (AGB) of intact and degraded forests of Kalimantan at 1 ha grid cells by combining field inventory plots, airborne lidar samples, and satellite radar and optical imagery. More than 110 000 ha of lidar data were acquired to systematically capture variations of forest structure and more than 104 field plots to develop lidar-biomass models. The lidar measurements were converted into biomass using models developed for 66 439 ha of drylands and 44 250 ha of wetland forests. By combining the AGB map with the national land cover map, we found that 22.3 Mha (106 ha) of forest remain on drylands ranging in biomass from 357.2 ±12.3 Mgha-1 in relatively intact forests to 134.2 ±6.1 Mgha-1 in severely degraded forests. The remaining peat swamp forests are heterogeneous in coverage and degradation level, extending over 3.62 Mha and having an average AGB of 211.8 ±12.7 Mgha-1. Emission factors calculated from aboveground biomass only suggest that the carbon storage potential of more than 15 Mha of degraded and secondary dryland forests will be about 1.1 PgC.

Hijacking CRISPR-Cas for high-throughput bacterial metabolic engineering : advances and prospects
Mougiakos, Ioannis ; Bosma, Elleke F. ; Ganguly, Joyshree ; Oost, John van der; Kranenburg, Richard van - \ 2018

High engineering efficiencies are required for industrial strain development. Due to its user-friendliness and its stringency, CRISPR-Cas-based technologies have strongly increased genome engineering efficiencies in bacteria. This has enabled more rapid metabolic engineering of both the model host Escherichia coli and non-model organisms like Clostridia, Bacilli, Streptomycetes and cyanobacteria, opening new possibilities to use these organisms as improved cell factories. The discovery of novel Cas9-like systems from diverse microbial environments will extend the repertoire of applications and broaden the range of organisms in which it can be used to create novel production hosts. This review analyses the current status of prokaryotic metabolic engineering towards the production of biotechnologically relevant products, based on the exploitation of different CRISPR-related DNA/RNA endonuclease variants.

Indian agriculture : unfolding structural changes and their relevance to the EU

India has emerged from the global financial crisis registering an estimated GDP growth of 8.6 per cent in 2010–11. Following a severe drought in 2009 agricultural growth bounced back to 5.4 per cent in 2010–11. Inter-state variations in agricultural performance – Gujarat is a front runner – can be explained by differences in investments in infrastructure, irrigation, R&D etc. There is potential to improve performance sustainably, keeping in view increasing stress on water resources and other environmental issues. More than 52 per cent of the workforce depends on agriculture, which accounts for 17 per cent of GDP. Per capita food expenditure averages more than 50 per cent of total expenditure. Overall income growth is triggering a shift in consumption from cereals to high-value commodities. To meet demand shifts, India can either increase domestic production and/or participate more in world markets. The Indian agri-food system is being transformed: farming is becoming integrated with input supplies, warehouse/logistics, processing and retailing, and the entire value chain is being streamlined. This is stimulating increased trade and investment opportunities in India. EU Member States may find opportunities in niche markets e.g. cheese, wine, olive oil, which are still in their infancy, or to invest in food technology, irrigation, farm management practices (especially dairy) or the development of sustainable value chains
