Sustainable Development

15.1K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Microorganisms in Agriculture and Food industry

Microorganisms play a crucial role in agriculture and the food industry, contributing to soil fertility, crop protection, and food production. Their functions range from nitrogen fixation and biopesticide production to fermentation and food preservation, making them indispensable to sustainable farming and food safety.Role in AgricultureNitrogen-fixing bacteria, such as Rhizobium (symbiotic) and Azotobacter (free-living), convert atmospheric nitrogen into ammonia through biological nitrogen...

Velocity of an Object01:18

Velocity of an Object

199
Understanding how an object moves along a path requires distinguishing between motion over a time span and motion at a precise moment. A useful example is a vehicle traveling along a straight and level path, where its position at any given time is known. The initial step in analyzing this motion is to measure how far the vehicle travels over a fixed time period. This measurement, called average velocity, is computed by dividing the total change in position by the duration over which the change...

Position-effect Variegation

In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.

Potential Due to a Polarized Object

770
A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the external electric force pulls the electrons and nucleus apart, opposite to the intrinsic attraction between the nucleus and the electrons. The opposing forces balance each other with a slight shift between the center of masses of the nucleus and the electron cloud, resulting in a polarized atom. On the other hand, a few molecules, like water,...

Potential Due to a Magnetized Object

793
Magnetic dipoles in magnetic materials are aligned when placed under an external magnetic field. For paramagnets and ferromagnets, dipole alignment occurs in the direction of the magnetic field. However, the dipoles align opposite to the field in the case of diamagnets. This state of magnetic polarization due to the external field is called magnetization. Magnetization is defined as the dipole moment per unit volume. It plays a similar role to polarization in electrostatics.
The vector...

Area of Science:

  • Agricultural Development
  • Rural Livelihoods
  • Sustainable Farming Systems

Background:

  • Agricultural development requires balancing food security, income, and environmental sustainability.
  • Household heterogeneity necessitates tailored strategies, yet existing diversity may offer solutions.
  • Trade-offs between development objectives pose challenges for selecting effective practices.

Purpose of the Study:

  • To introduce and test an adapted Positive Deviance approach for identifying multi-objective agricultural development practices.
  • To uncover locally viable livelihood strategies from high-performing rural households.
  • To inform targeted recommendations for diverse farming households in comparable resource contexts.

Main Methods:

  • Quantitative survey of over 500 rural households in South-Eastern Tanzania.
  • Identification of 54 'positive deviant' households excelling across food security, income, nutrition, environmental sustainability, and social equity.
  • Qualitative interviews with a sub-sample to identify specific 'deviant' practices contributing to superior outcomes.

Main Results:

  • Positive deviant households demonstrated superior food security and slightly better social equity compared to similar households.
  • Fourteen uncommon, locally viable practices were identified as plausibly contributing to outstanding household performance.
  • The Positive Deviance approach successfully identified practices linked to multi-dimensional household success.

Conclusions:

  • The adapted Positive Deviance approach is effective for identifying context-specific agricultural practices that enhance multiple development objectives.
  • Empirical observation of high-performing households can guide the development of sustainable and equitable agricultural solutions.
  • This method provides a framework for leveraging local knowledge and diversity in agricultural development planning.
