The global energy challenge: second-generation feedstocks on marginal lands for a sustainable biofuel production

Chemical and Biological Technologies in Agriculture, Journal Year: 2025, Volume and Issue: 12(1)

Published: Jan. 17, 2025

As the global population continues to grow, so does demand for energy resources. a consequence, using renewable sources as an alternative fossil fuels has become mandatory reduce environmental footprint of sector. Biofuels represent source energy, but their production raised concerns regarding possible impacts on food security. Indeed, current biofuel primarily relies crops and arable lands. That is in conflict with need produce more increasing world population. To overcome this incongruence, it proposed cultivate second-generation marginal lands, since option could bring benefits terms security sustainability. Based scientific literature, we addressed following critical points: (i) whether land worldwide can be considered reasonable lands production; (ii) evaluate sustainability respect unintended negative consequences crop cultivation such indirect use change, social insecurity loss biodiversity. It was concluded that amount growing plants possibly sustain both if are included. In context, becomes priority select high productivity pronounced resilience adaptability traits. Underutilized Carthamus tinctorius, Ricinus communis, Brassica carinata, Camelina sativa etc. may fit purpose valuable first-generation feedstock because they require minimal agronomical input. Using underutilized also provide important ecological services, including improving soil fertility water regulation, biodiversity reducing erosion. fully exploit option, will calibrate plant growth models estimate potential from create tools rational management land.

Sustainability Potential of Marginal Areas for Food, Feed, and Non-Food Production in the Puglia Region, Southern Italy: Part II: A Review

Agronomy, Journal Year: 2024, Volume and Issue: 14(3), P. 472 - 472

Published: Feb. 27, 2024

There is considerable unused and unproductive land in rural areas of the Puglia region, Southern Italy. These their local cultivators/growers have always been overlooked by academic, policy, investment circles despite potential to improve food security livelihood communities. Therefore, it crucial evaluate sustainability these produce food, feed, non-food products. This evaluation will play a vital role sustainable development regions such as region. In this review, we highlighted important aspects regarding management expected contribution that various types marginal (MAs) could add regional economy Puglia. The authors focused on extent which Puglia’s lands can realistically be utilized meet Italy’s production targets, considering economic, social, environmental different area within territories. writing inspired lack sufficient information necessary carry out plan for revitalization MAs areas. Although Italian scholars not extensively researched MAs, available data suggest they significantly contribute security, complexity low-input nature. scientific evidence suggests main challenge associated with using and/or balancing biodiversity conservation residents’ social economic development. Presently, some small-scale or family farms are already operating MAs. However, still minimally overall agricultural even though an numerous communities Furthermore, indicate over 40% existing farmers require greater support sustain activities. Such should tailored context, built and, where appropriate, improved upon practices, while addressing threats regard, policies shape MAs’ landscapes through initiatives aimed at recovery traditional activities, use varieties, protection environment, biodiversity. believe review provides policymakers recommendations consider when supporting source people living

Accurate acquisition of spatial and temporal distribution information for cropping systems is important agricultural production food security. The challenges extracting about in regions with smallholder farms are considerable, given the varied crops, complex patterns, fragmentation cropland frequent reclamation abandonment. This study presents a specialized workflow to solve this problem farms, which utilizes field samples Sentinel-2 data extract system over multiple years. involves four steps: 1) processing simulate crop growth curves Savitzky‒Golay filter computing feature variables classification, including phenology indices, spectral bands, time series vegetation indices; 2) mapping annual croplands one-class support vector machine; 3) various single cropping, intercropping, double harvest, fallow by decision tree K-means clustering; 4) crops random forest where Jeffries-Matusita distance was used select appropriate indices. applied Hetao irrigation district Inner Mongolia Autonomous Region, China from 2018 2021. overall accuracies were 0.98, 0.96, 0.97 cropland, type mapping, respectively. results indicated that area has low continuity dominated patterns. Furthermore, wheat cultivation decreased, vegetable expanded. Overall, proposed facilitated accurate demonstrated effectiveness available imagery classifying on Google Earth Engine.

Shaping the European Alps: Trends in landscape patterns, biodiversity and ecosystem services

CATENA, Journal Year: 2023, Volume and Issue: 235, P. 107607 - 107607

Published: Nov. 4, 2023

Landscape appearance is controlled by a range of different environmental and human-induced factors, although there still lack knowledge about the significance individual factors. Our goal was to identify factors that were significant for landscape change in European Alps rank them according their importance. Therefore, we mapped with standardized survey methodology six typical socio-ecological regions strongly differing socio-economic natural conditions. The results clearly showed has taken place all over last 150–200 years, affecting biodiversity ecosystem services (ES). In general, areas used agriculture have decreased regions, particularly traditionally forms (−72.7 % −6.9 %). greatest decrease took high elevation, agriculturally unfavourable (-72.6 −41.6 %) weak economic conditions (−62.9 −20.9 forest spread on large scale abandoned land economically strong but also settlements monotone intensively cultures. As consequence changes, plant species diversity declined, favourable good site (−62.7 −7.2 %), while it far less (−20.1 −0.7 Regulation & maintenance cultural ESs decreased, whereas provisioning ES generally increased. regional framework play much more important role development than national frameworks. Higher "green subsidies" reduced intensification trend agriculture, led increased abandonment. addition, remained diverse, declined many This demonstrates interpreting historical dynamics analysing impacts can be valuable guide sustainable decision-making processes.
