Knowledge of how many sampling points are needed to estimate the mean content of soil nutrients in agricultural fields, given a precision requirement on the estimated mean, is limited. This paper describes a versatile geostatistical simulation approach for predicting the variance of the mean nitrate-N (NO3-N) content within an agricultural field es...

Animal manure used to be the major source of additional nutrients and crucial for maintaining soil fertility and crop yield in traditional farming systems. However, it is increasingly not recycled, wasting vital resources and damaging the environment. By using long-term (1986–2017) data from a rural household survey (>20,000 households) across Chin...

The effectiveness of green mussel (Perna viridis) cultivation was compared between longline culture and the traditional bamboo stake method using different mussel densities in a rural area on the north coast of Java, Indonesia. The study took place in a rural area about 2 km north-east from the city of Semarang where unsustainable shrimp and fish p...

Rapidly changing hydrological conditions under climate change, upstream developments, and local water infrastructures require transformative changes in water management strategies for the agriculture sector in the Vietnamese Mekong Delta (VMD). For more than three decades, the agricultural policies in Vietnam have emphasized the intensification of ...

The sustainability transitions research field continues to broaden rapidly, engaging scholars from a wide variety of disciplinary backgrounds. As highlighted in the STRN research agenda, transitions research relies on a broad range of methodological approaches; yet the methodological diversity of transitions studies has remained somewhat limited. I...

Poly(ethylene 2,5-furandicarboxylate) (2,5-PEF) is one of the most credible biobased alternative to poly (ethylene terephthalate) (PET). The Henkel disproportionation reaction that leads to furandicarboxylic acid (FDCA) provides three position isomers: 2,5-FDCA (obtained with the highest yield), 2,4-FDCA (so far considered as a by-product), and 3,4...

Improvements in ex situ storage of genetic and reproductive materials offer an alternative for endangered livestock breed conservation, but collections should be optimized cost-effectively to avoid duplication, and with reference to the sustainability of in situ breeds. We developed a multi-period chance-constrained optimization model to rationaliz...

LED lighting is appointed as the successor of HPS lighting in greenhouses since it can lead to a more sustainable cultivation, i.e. it converts electrical energy into photosynthetically active radiation more efficiently. To quantify the effect of this more efficient conversion within the operation of the greenhouse system, an optimal controller is ...
