AbstractWater security is a global concern sharpened by the biggest humanity challenge of climatic crisis. With the end of designing and implementing efficient and sustainable water management strategies, it is necessary to recognize the interdependence and coevolution between natural and social systems and understand how the double way relationships between these systems shape sustainability. The socio‐ecological systems (SES) sustainability approach is an alternative to this end. Conceptual challenges have been identified in the analysis of the sustainability of SES.

Abstract

Successfully analyzing and managing trade-offs between community welfare and wildlife conservation are complex tasks that require a multidisciplinary approach and consideration of various factors. Bioeconomic modeling provides a structured quantitative framework for understanding and evaluating the complex interactions between biological systems and economic activities, aiding in the crafting of more effective and sustainable conservation and rural development strategies.

AbstractNigeria is facing the problem of soil degradation as a result of continuous deposition of spent oil in the soil. The physiochemical properties, including heavy metals concentrations, of spent oil contaminated soils and adjacent control soils were investigated at 0–15 and 15–30 cm depths at Ladipo and Berger auto-mobile Markets in Lagos, southwest Nigeria. The soils were collected in triplicate and analyzed in a 2 (location) * 2 (study site) * 2 (soil depth) factorial experiment.

Abstract

This paper presents a global synthesis of economic values for ecosystem services provided by 15 terrestrial and marine biomes. Information from over 1,300 studies, yielding over 9,400 value estimates in monetary units, has been collected and organised in the Ecosystem Services Valuation Database (ESVD). This is a substantial expansion of data since the de Groot et al. (2012) description of the ESVD and provides an important juncture to explore developments in the use of valuation methods and the contexts in which valuations are conducted.

In this study, we estimate the marginal effects of increasing forest cover on dengue prevalence in Costa Rica using econometric models to relate hospital admission records to forest cover maps from 2001 and 2011. We find that increasing the percentage of forest cover significantly decreases both the number of hospital admissions for dengue and the probability of an outbreak.
