You could order a lecture in the following topics:

The Judean Desert and Dead Sea- the uniqueness of the area, ongoing processes and predictions to the future
In this lecture we will discuss the reason for the formation of the Judean Desert- the smallest desert in the world, and the Dead Sea- the lowest place on earth. We will discuss the geomorphologic characteristics that turn this small area into such a complex and interesting place. We will also learn about the role this desert played in the history of the land, and the three major monotheistic religions. The last part of the lecture will be dedicated to learning about the processes happening today in the Dead Sea, and predictions to the future.
Desertification in Israel- an irreversible phenomenon or a controllable phenomenon?
In this lecture, based on my final work in my M.A. studies in environmental studies in the Tel Aviv University, we will understand the difference between desert and desertification. We will analyze what are the causes for desertification in the area of Israel, and what can be done to fight this phenomenon. We will learn about the pioneering history of Israel, what happened to the forests that were here in biblical times, and what actions were undertaken as part of the Zionist vision of making Israel green again. We will learn about the chances and risks that lye in the future of the desertification field, which stands at the front of the science worldwide today.
Reintroduction of extinct species to Israel:
In this lecture we will focus on efforts that were done in the past and are still done today to retrieve four kinds of large mammal herbivores- the Persian Fallow Deer, the Arabian Oryx, the Roe Deer and the Asiatic Wild Ass to the wild. We will learn about the processes that led to extinctions in the past, the fragility of the biological diversity in Israel, the vision of two people who decided to act way before there was sufficient scientific knowledge, and about covered operations and the last flight from Iran to Israel that included very important passengers. We will also learn about modern field management and successes and failures over the years and about predictions to the future.
The Nabateans and Nabatean incense routes and cities in the Negev Desert:
In this lecture we will learn about a mysterious nation, a nation that had an important role in shaping the culture of the old world, around the Mediterranean Sea for centuries, and eventually disappeared without leaving a trace. Who were the mysterious Nabateans, who knew how to find water where other people couldn't survive, who started out as people that would not plant trees or build houses, but thrived on trade in priceless incense and eventually built cities that were declared world heritage sites?
What was the secret of their success and what eventually led to their disappearance from the historical map?
What can we see today, and what trips can we do in the footsteps of this mysterious nation?
Opening the way to Jerusalem in the war of independence:
In this lecture we will learn about fighting in shortage conditions, against a stronger foe, for keeping the tradition of a nation free in its own country, who's capital is Jerusalem, that started three thousand years ago. We will tell the story of the Palmah Har'el Brigade, the only brigade in the Israeli Defense Force that "won" the honor of having its very own graveyard, and of the 7'nth Brigade, the first armored brigade of the Israeli Defense Force. We will tell about the stories of the valley's gate, about capturing the Latrun military posts by the Jordanian Legion, and the frantic efforts to take them back, and to find a way around them, while the battles are still going on, to open the way to the besieged Jerusalem. We will discuss the importance of the effort done back then, in a very small sector of the front, and the implications these battles have on our lives until today.
