Crop Agnostic Monitoring Driven by Deep Learning

Farmers require diverse and complex information to make agronomical decisions about crop management including intervention tasks. Generally, this information is gathered by farmers traversing their fields or glasshouses which is often a time consuming and potentially expensive process. In recent years, robotic platforms have gained significant traction due to advances in artificial intelligence. However, these platforms are usually tied to one setting (such as arable farmland), or algorithms are designed for a single platform. This creates a significant gap between available technology and farmer requirements. We propose a novel field agnostic monitoring technique that is able to operate on two different robots, in arable farmland or a glasshouse (horticultural setting). Instance segmentation forms the backbone of this approach from which object location and class, object area, and yield information can be obtained. In arable farmland, our segmentation network is able to estimate crop and weed at a species level and in a glasshouse we are able to estimate the sweet pepper and their ripeness. For yield information, we introduce a novel matching criterion that removes the pixel-wise constraints of previous versions. This approach is able to accurately estimate the number of fruit (sweet pepper) in a glasshouse with a normalized absolute error of 4.7% and an R2 of 0.901 with the visual ground truth. When applied to cluttered arable farmland scenes it improves on the prior approach by 50%. Finally, a qualitative analysis shows the validity of this agnostic monitoring algorithm by supplying decision enabling information to the farmer such as the impact of a low level weeding intervention scheme.

Production-Integrated Compensation in Environmental Offsets—A Review of a German Offset Practice

Environmental offset schemes designed to compensate for adverse development impacts are found in countries worldwide, pursuing no-net-loss policy. In Germany, a practice combining environmental improvements with farming evolved in the early 2000s, known as production-integrated compensation (PIC) (Produktionsintegrierte Kompensation). This paper provides a review of PIC, presenting origins, legal and cost aspects, as well as examples of PIC practice. PIC key challenges are the complexity of environmental improvements of agrarian habitats and the high efforts for communication among diverse actors and for designing and monitoring PIC. Benefits for nature conservation lie in the protection of strongly endangered species and an increase of acceptance of compensation measures. Positive effects for farmers are the sustaining of arable farmland and involvement in setting up land management terms. Investors profit from the increased availability of sites. However, a specific legal framework for PIC is still developing and representation of PIC in offset registries in the German States is only very small. In conclusion, targeted design, continuous monitoring, and long-term financing provided, PIC may (a) increase offset efficiency by focusing on implementation while avoiding land purchase and physical investments and (b) increase offset effectiveness by high conservation benefits and a collaborative approach towards farmers.

Rapid rise in toxic load for bees revealed by analysis of pesticide use in Great Britain

A strong argument can be made that the European Union has the most rigorous regulatory system for pesticides in the world, and that modern pesticide use poses fewer environmental threats than older regimes. Nevertheless, the impacts of pesticides on bees and other non-target organisms are much debated in Europe as elsewhere. Here we document changing patterns of pesticide use in arable and horticultural crops in Great Britain from 1990 to 2015. The weight of pesticides used has approximately halved over this period, but in contrast the number of applications per field nearly doubled. The total potential kill of honeybees (the total number of LD50 doses applied to the 4.6 million hectares of arable farmland in Great Britain each year) increased six-fold to approximately 3 × 1016 bees, the result of the increasing use of neonicotinoids from 1994 onwards which more than offset the effect of declining organophosphate use. It is important to stress that this does not mean that this number of bees will be killed, and also to acknowledge that our simple analysis does not take into account many factors such as differences in persistence, and timing and mode of application of pesticides, which will affect actual exposure of non-target organisms. Nonetheless, all else being equal, these data suggest that the risk posed by pesticides to non-target insects such as bees, other pollinators and natural enemies of pests, has increased considerably in the last 26 years.

Multi-criteria Decision Analysis Approach to Mine Closure Planning - A Case Study

As mining and environmental regulations continue to get tighter on mine closure and reclamation, the choice of an optimal post mining land use becomes critical if mining companies are to continue enjoying the peaceful co-existence they have with their local communities. In this study, possible mine closure alternatives have been identified as suitable for the Salman south pit of Adamus Resources Limited in the Western Region of Ghana. These alternatives are: arable farm land; timber production; shrubs and native forestation; aquaculture; water reservoir; land fill; and recreational site (park). Effective consideration has been given to the identified technical, environmental, economic, and social criteria to assist in the determination of the optimal choice among the identified suitable closure alternatives. Using the Preference Ranking Organisation Method for Enrichment Evaluation (PROMETHEE) technique of multi-criteria decision analysis, it was observed from the results that arable farmland was the most preferred choice followed very closely by timber production. Others like aquaculture, recreational site (park), shrubs and native forestation, water reservoir, and landfill followed in a decreasing order. In order to satisfy all the various stakeholders in the mine closure process, it is therefore recommended that arable farmland and/or timber production be adopted as the optimal post mining land use for the study area.
