PROFILE : My journey to Professional Registration - Innocent Gininda

Innocent Gininda shares his journey to becoming a registered Professional Engineer (PrEng), emphasizing the importance of mentorship, early preparation, and understanding ECSA requirements. He offers advice to aspiring PrEngs, highlighting the value of diverse feedback and a positive mindset. My journey to becoming a registered Professional Engineer (PrEng) culminated successfully in November 2024. I was fortunate to begin my career at a company with a Commitment and Undertaking (C&U) Agreement with ECSA and a robust mentorship program. This commitment to training engineers to the standard required for Professional Registration provided me with essential resources and a structured path to track my experience against ECSA requirements. Early exposure to these expectations instilled a positive outlook on registration and solidified my desire to achieve this milestone. My views on Professional Registration have remained consistently positive throughout this journey. Working alongside ...

REVIEW : The surge in hydroelectric dams is driving massive biodiversity loss

Globally,natural rivers with unimpeded flow are becoming increasingly fragmented due to the construction of dams, weirs, and other barriers. This is one of the most significant, yet often overlooked, drivers of biodiversity loss worldwide.


A recent report by the Living Planet Index indicates that river fragmentation is a significant factor in the 81% decline in migratory fish populations since 1970, which is six times higher than the rate of loss for land and sea animals.

Migratory fish, such as salmon and eels, need to move between different parts of rivers, estuaries, and oceans at various life stages. Salmon, for example, migrate from the sea to rivers or lakes for reproduction, while eels do the reverse. Therefore, it is essential to preserve free-flowing rivers to allow species and nutrients to pass from upstream headwaters to downstream floodplains, deltas, and estuaries.

Remediating the catastrophic impact of river fragmentation on migratory fish species is possible, but it requires significant and urgent engineering interventions that effectively balance the need for water storage in reservoirs with the preservation of freshwater biodiversity.
