Natural capital investments in China undermined by reclamation for cropland

Nature Ecology & Evolution, Journal Year: 2023, Volume and Issue: 7(11), P. 1771 - 1777

Published: Sept. 25, 2023

Abstract Globally, rising food demand has caused widespread biodiversity and ecosystem services loss, prompting growing efforts in ecological protection restoration. However, these have been significantly undercut by further reclamation for cropland. Focusing on China, the world’s largest grain producer, we found that at national level from 2000 to 2015, cropland undermined gains wildlife habitat of water retention, sandstorm prevention, carbon sequestration soil retention 113.8%, 63.4%, 52.5%, 29.0% 10.2%, respectively. To achieve global sustainability goals, conflicts between inefficient natural capital investment need be alleviated.

The input reduction principle of agroecology is wrong when it comes to mineral fertilizer use in sub-Saharan Africa

Outlook on Agriculture, Journal Year: 2023, Volume and Issue: 52(3), P. 311 - 326

Published: Sept. 1, 2023

Can farmers in sub-Saharan Africa (SSA) boost crop yields and improve food availability without using more mineral fertilizer? This question has been at the center of lively debates among civil society, policy-makers, academic editorials. Proponents “yes” answer have put forward “input reduction” principle agroecology, i.e. by relying on agrobiodiversity, recycling better efficiency, agroecological practices such as use legumes manure can increase productivity need for fertilizer. We reviewed decades scientific literature nutrient balances SSA, biological nitrogen fixation tropical legumes, production smallholder farming systems, environmental impact Our analyses show that fertilizer is needed SSA five reasons: (i) starting point agricultural “agroecological” default, is, very low use, widespread mixed crop-livestock systems large diversity including but leading to poor soil fertility a result mining, (ii) needs crops cannot be adequately met solely through animal manure, (iii) other nutrients like phosphorus potassium replaced continuously, (iv) fertilizers, if used appropriately, cause little harm environment, (v) reducing fertilizers would hamper gains contribute indirectly expansion deforestation. Yet, principles directly related fertility—recycling, diversity—remain key improving health nutrient-use are critical sustaining long run. argue nuanced position acknowledges combination with adequate policy support.

Global spatiotemporal optimization of photovoltaic and wind power to achieve the Paris Agreement targets

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: March 3, 2025

Limiting global warming below 1.5 or 2 °C calls for achieving energy systems with net-zero carbon dioxide (CO2) emissions likely by 2040 2070, but the pledged actions under current policies cannot meet these targets. Few studies have optimized deployment of photovoltaic and wind power. Here we present a strategy involving construction 22,821 photovoltaic, onshore-wind, offshore-wind plants in 192 countries worldwide to minimize levelized cost electricity. We identify large potential reduction combining coordination storage power transmission, dynamics learning, trade minerals, development supply chains. Our optimization increases capacity power, accompanied average abatement from US Dollars ($) 140 (baseline) $33 per tonne CO2. study provides roadmap CO2 emissions, emphasizing physical, financial, socioeconomic challenges forward.

Climate and land-use change homogenise terrestrial biodiversity, with consequences for ecosystem functioning and human well-being

Emerging Topics in Life Sciences, Journal Year: 2019, Volume and Issue: 3(2), P. 207 - 219

Published: April 24, 2019

Abstract Biodiversity continues to decline under the effect of multiple human pressures. We give a brief overview main pressures on biodiversity, before focusing two that have predominant effect: land-use and climate change. discuss how interactions between change in terrestrial systems are likely greater impacts than expected when only considering these isolation. Understanding biodiversity changes is complicated by fact such be uneven among different geographic regions species. review evidence for variation changes, relating differences species key ecological characteristics, explaining disproportionate certain leading spatial homogenisation communities. Finally, we explain overall losses larger upon types species, lead strong negative consequences functioning ecosystems, consequently well-being.
