Ten facts about land systems for sustainability

Proceedings of the National Academy of Sciences, Journal Year: 2022, Volume and Issue: 119(7)

Published: Feb. 7, 2022

Land use is central to addressing sustainability issues, including biodiversity conservation, climate change, food security, poverty alleviation, and sustainable energy. In this paper, we synthesize knowledge accumulated in land system science, the integrated study of terrestrial social-ecological systems, into 10 hard truths that have strong, general, empirical support. These facts help explain challenges achieving thus also point toward solutions. The are as follows: 1) Meanings values socially constructed contested; 2) systems exhibit complex behaviors with abrupt, hard-to-predict changes; 3) irreversible changes path dependence common features systems; 4) some uses a small footprint but very large impacts; 5) drivers impacts land-use change globally interconnected spill over distant locations; 6) humanity lives on used planet where all provides benefits societies; 7) usually entails trade-offs between different benefits—"win–wins" rare; 8) tenure claims often unclear, overlapping, 9) burdens from unequally distributed; 10) users multiple, sometimes conflicting, ideas what social environmental justice entails. implications for governance, do not provide fixed answers. Instead they constitute set core principles which can guide scientists, policy makers, practitioners meeting use.

Landscapes—a lens for assessing sustainability

Landscape Ecology, Journal Year: 2025, Volume and Issue: 40(2)

There are urgent calls to transition society more sustainable trajectories, at scales ranging from local global. Landscape sustainability (LS), or the capacity for landscapes provide equitable access ecosystem services essential human wellbeing both current and future generations, provides an operational approach monitor these transitions. However, complexity of complicates how what consider when assessing LS. To identify important features that remain challenging in LS assessments guidance strengthen assessments. We conducted two workshops complex under-considered assessments, developed guidelines on better incorporate features. open connected boundaries diversity values as landscape must be considered risk exacerbating offstage burdens power inequalities. avoid pitfalls which emphasize service interactions across interconnected incorporating actors' diverse values. Our a stepping stone researchers practitioners complexities into inform landscape-level decisions actions.

Impacts and economic costs of climate change on Mexican agriculture

Regional Environmental Change, Journal Year: 2022, Volume and Issue: 22(4)

Abstract This study quantifies the impacts of climate change on yields and corresponding economic losses in six relevant crops that account for 65% harvested area Mexico are highly terms consumption value. The results show crop could decrease considerably during this century, especially rainfed management system. Under a high-emission scenario, large reductions expected by end century both irrigated systems maize (42%, 31.4%), rice (51.4%, 41.3%), sorghum (41.1%, 36.6%), soybean (59.1%, 44.9%), wheat (23.3%, 20.0%), sugarcane (11.7%). At national level, present value selected amounts to $37,934 million dollars, which represents about twice current total agricultural production Mexico. Rainfed agriculture 69% these almost 70% losses. States such as Veracruz, Sinaloa, Tamaulipas, Jalisco represent half However, 16% aggregated occur states with high levels poverty subsistence farming like Chiapas, Oaxaca, Guerrero. Climate will significantly increase risks already vulnerable farmers’ face present. Although ambitious mitigation efforts can reduce estimated most crops, residual damages considerable, prompt implementation adaptation strategies is required.

Estimating Fragmentation and Connectivity Patterns of the Temperate Forest in an Avocado-Dominated Landscape to Propose Conservation Strategies

The rapid expansion of avocado cultivation in Michoacán, Mexico, is one the drivers deforestation. We assessed degree fragmentation and functional connectivity remaining temperate forest within Avocado Belt prioritized patches that contribute most to using a network-based approach modelling different seed pollen dispersal scenarios, including two types patch attributes (size conservation). As landscape transformation region ongoing, we updated land-use land-cover maps through supervised classification Sentinel-2 imagery, improving reliability our analyses. Temperate highly fragmented region: are small (<30 ha), have reduced core-area (28%), irregular shapes. very low (0.06), dropping 0.019 when conservation was considered. top 100 ranked support seeds characteristics (i.e., size topology) may be considered for implementing management strategies. Seed seems more threatened by than dispersal, important maintaining embedded denser zone orchards.

The socio-environmental impacts of tropical crop expansion on a global scale: A case study in cashew

Biological Conservation, Journal Year: 2023, Volume and Issue: 280, P. 109961 - 109961

Published: Feb. 20, 2023

Tropical crops like cashew (Anacardium occidentale) receive limited socio-ecological research attention despite expansion in regions of high biodiversity. We investigated how plantations affected biodiversity and livelihoods globally by conducting a systematic literature review modelling the potential overlaps between land suitability threatened vertebrates. Nine studies on effects from India, Guinea- Bissau Nigeria showed four to 84 % species richness reductions for fungi, plants, butterflies, birds, terrestrial mammals across 'reference habitats' such as forests, woodlands, coffee sand dunes. Three reported that harboured subset generalist butterfly bird when compared coffee, forests with no evidence forest-dependent cashew.

Irrigation Alternatives for Avocado (Persea americana Mill.) in the Mediterranean Subtropical Region in the Context of Climate Change: A Review

Agriculture, Journal Year: 2023, Volume and Issue: 13(5), P. 1049 - 1049

Published: May 12, 2023

Due to congenital features, avocado (Persea americana Mill.) trees are substantial water users relative other fruit trees. The current growing deficiency of resources, especially in arid and semi-arid avocado-producing areas, has led the demand for more sustainable water-saving measures. objective this review was analyze role deficit irrigation as a strategy face climate change scarcity through achieving efficiency, saving water, maximizing benefits that could be achieved at level irrigated agricultural system. Particular attention is devoted studies performed subtropical Mediterranean climate, which orchards common. These analyzed demand, irrigation, determination status physiological parameters, leading possible programs context shortage scenarios. Through these insights, we conclude under climatic circumstances with respect available farming requires resilience strategies reduce consumption without affecting yield quality fruits. Water stress inevitably affects processes determine yield. Therefore, an admissible loss required smaller fruits savings made strategies. In addition, modern consumers tend prefer foods based on sustainability, i.e., there high socially responsible environmentally friendly products.
